CLUTTON-BROCK WITH PREFACE AND NOTES BY MRS. FRANCIS KING AUTHOR OF “THE WELL-CONSIDERED GARDEN” NEW YORK CHARLES SCRIBNER’S SONS 1916 Coprricut, 1916, BY CHARLES SCRIBNER’S SONS Published November, 1916 (22193 ¢% Publication in the United States authorized by the London Times PREFACE Tue title of this book does not belie its contents. Within these covers lies matter for the consideration of those who think about gardening as well as for those who see and practice it. Unlike other gardening books in its light-hearted choice of topics it is also unlike them in its high charm of manner, in a certain urbanity to which we confess ourselves unaccustomed. Never was a lighter pen than this, never such a pen so well-di- rected. For gardening, and more especially the appre- ciation of the art of garden design, are matters upon which much light needs to be thrown for the amateur in this country. Certain chapters of “Studies in Garden- ing” should be read before every progressive garden club in America; the two on “The Theory of Garden Design,” “Common Sense in Gardening,” “The Right Use of Annuals,” “The Problem of the Herbaceous Border,” “The House and the Garden,” and that portion of the Introduction entitled “The Planning of the Garden.” And what delectable learning is stored in these pages! The tribute of tributes is most surely paid to a book one has been asked to annotate when the would- be critical reader becomes so absorbed in its pages as to forget the critical attitude. So entirely is “Studies in Gardening” what a book on gardening should be, Vv vi PREFACE so entirely is it what no other has yet been, that to keep from overpraise is difficult. There may be, there will be those to whom a few matters of individual taste in these pages may not commend themselves. This would be always so, whoever wrote, whoever read. The point to be noticed is this: the taste of the author of “Studies in Gardening” is with rare exceptions based on principles and, therefore, cannot but be sound. When one reflects upon the lack of knowledge of the principles of gardening among our own amateurs one feels more keenly the need of such a leaven as this book affords. General enlightenment on the great subject is our instant want; more study of the broader aspects of the gardening art, enlivening this of course by constant excursions into the lovely realm of flower, shrub, and tree, matters of garden enclosure and gar- den decoration. It will be noticed that among the plant subjects considered in the present volume there are some not to be recommended for our Northern States for reasons of soil and climate. It has seemed wise to leave these names unchanged, adding on occasion an explanatory note. Many of these plants flourish in our Northern Pacific States as in England, and of certain parts of the South and Southwest the same may be said. The difference in climate with regard to time of bloom of plants dealt with here makes the suggestion fitting that the reader allow a date one month later for the latitude of Boston. This opinion is based upon care- PREFACE vii ful notes, kept for many years and constantly com- pared with like notes in English journals. I wish we might impress upon the American gardener (and by gardener I mean of course the amateur) the fact that the good English book carries as much value for him as for the Englishman. It is easy to learn the distinctions between English climate, English soils and the soils and climate of this country; and while good sense compels us to believe in the use of those subjects known to be suited to our country, our own estates or bits of ground, we must still look across seas for most of our finer garden books, and in so looking, we invariably find fresh and excellent ma- terial for our beds and borders. Many unfamiliar names occur in the course of the book. It chances that nineteen varieties of Dianthus are brought into the dissertation on Pinks. I ven- ture to think most of these unknown to the average gardener, but why should he not add them to his present knowledge of the genus? Bailey lists twenty- six! Nurserymen will respond to calls for these things. Here is a little foot-hill of horticulture which any one may climb if he will. Let us not level it by means of notes, but rather urge the ambitious gar- dener to ascend the slope and there achieve a view so fair, so satisfying, that he will wonder that he thought the climb a heavy or laborious thing. And how accustomed are we in America, those of us who garden, to being written down to! How sel- dom in our young literature of gardening may we vili PREFACE gather the grateful inference of a little practical knowl- edge on our part and a bit of taste to boot! We need books to lift us, not to continually presuppose our ignorance. We need books to stimulate our search for garden learning, to send us hunting meanings of names new to us. America is passing from her gar- dening infancy to her gardening youth. This youth, filled with the romance and beauty of the newly dis- covered art, is ready for the best in garden writing. Wherefore a book like this is thrice welcome. Its writer has that wide outlook upon the subject denied to all but few. The book has a virility seldom en- countered in writings of this character. It shows a large practical and personal acquaintance with plants, and an equally wide knowledge of the principles of fine gardening. Joined to these qualities a love of beauty shines through every page, a charming humour will out upon occasion, and an entirely delightful English style enwraps the whole. American gar- dening cannot but be richer, finer, for every reader of this book. “It is” exclaims a correspondent lately, “the Englishman at his highest and best. Hear these words: ‘But a single flowering shrub rightly placed in front of a dark barrier of greenery has your eye to itself and satisfies it, like an altar piece in a quiet church.’ Can we forget a sentence like that? I have seldom read a book with an intenser pleasure.” The chapters of this book appeared in the form of letters to the Times (London). The subjects seem to have been taken at random, for in three instances PREFACE ix only are the articles explicitly related to each other. It has seemed well therefore to allow the order of chapters to stand as in the English edition. Grateful acknowledgment is here made for val- uable help given by Mr. Hubert M. Canning and Mr. Wilbur F. Dubois; also by Dr. Alfred Rehder of the Arnold Arboretum to whom I owe the note on Cytisus. Louisa Yeomans Kine.

There is no need to speak of the practical articles in this introduction; but it may be as well to say something about the general principles upon which the theoretical articles are based. ‘Those principles are concerned mainly with the planning of gardens and with the character of the flowers that should be planted in them. The writer is in favour of the formal planning of gardens, and in this introduction he proposes to give some general reasons for his preference. But he cannot deny himself the pleasure of a rock garden, although he knows that a rock garden cannot well be worked into any formal design. In this matter he sins with many excellent gardeners, who are not likely to give up their rock gardens from any artistic scruple. Rock gardens exist, and more of them are made every year. In some respects they have had a good effect upon other kinds of gardening. We must therefore make the best of them. This introduction, then, will deal with rock gardens, and will attempt to show, first, what is the secret of their delight, and, secondly, how they can best be placed and planned so as to spoil the design of a formal garden as little as possible. xiv INTRODUCTION The third matter to be dealt with is the character of garden flowers; and this is more controversial even than the first two. The writer’s remarks on this sub- ject have already provoked some controversy and met with more agreement. He repeats them here because they are based upon the general principles which he has tried to express in all his theoretical articles, and because they still seem to him as true as when he first wrote them. But we will begin first with the most important matter, and that is — Tut PLANNING OF GARDENS Nothing in gardening is so difficult as the planning of a garden; and it ispeculiarly difficult now, because we are still in the‘midst of a revolution, a return to nature, which has upset all the old ideas and conven- tions of garden design both good and bad. This re- turn to nature has done much good in destroying some of the worst fashions of fifty years ago. It has taught us to love plants for their natural beauty and to grow them so that their natural beauty may be shown to the best advantage. It has, indeed, revived the whole art of horticulture, which in the gardens of the rich had shrunk, a generation or two ago, into the cultivation of a few dull bedding plants under the most unnatural conditions. But it has not taught us, nor can it teach us, the art of garden design. For a garden is, and always must be, something quite dif- ferent from a wild paradise of flowers, and no art can turn it into one. Flower borders are artificial things, INTRODUCTION XV and so are lawns and gravel paths. If we are to follow nature in the design of our gardens we must do with- out these, and even the wildest of wild gardeners will scarcely go so far as that. We should remember that the discredited landscape gardening of the last cen- tury, with its “specimen” conifers, its irrelevant shrubberies, and its aimlessly circuitous paths, was itself an attempt to imitate nature. We are sick of it now, not, as many suppose, because it was un- natural, but because it was ugly; and it is an interest- ing fact that William Morris, writing so far back as the end of the seventies, attacked landscape garden- ing, not for its artificiality, but for its lack of order and design. He, with all his love of wild beauty, of woods and meadows, said that a garden should “by no means imitate either the wilfulness or the wildness of nature, but should look like a thing never to be seen except near a house.” He knew that no work of art should put on the airs of nature; that, as houses ought not to be built to look like caves, so gardens ought not to be designed to look like flowery meadows or stretches of woodland. The beauty of nature is one thing; the beauty of art another. Each has its own romance, its own peculiar appeal to our memories and affections; and these different appeals cannot be combined in one. The love of gardens has always been so deep in Englishmen that it survived even when their love of all other beautiful things seemed for a while to be dead; and, when they built the ugliest houses, they xvi INTRODUCTION wished to forget the ugliness of them in their gardens. Thus it was that landscape gardening came into fash- ion. It was an attempt to ignore the existence of the house. Shrubberies were grown to hide it as best they could, and paths twisted about in a vain reluctance to approach it. But when men built beautiful houses they had no desire for landscape or for any kind of wild gardening. They were proud of their handiwork, and did not look to nature or any pretence of nature to conceal it from them. .The garden was as much a part of their conquest of nature as the house itself; and, like the house, they designed it to be expressive of the will and the purposes of man. So the house and the garden were all part of one design, of which the house was the centre, giving a purpose and mean- ing to the whole; and this idea that the house shall dominate and explain the garden is the principle upon which all formal gardening is based, whereas all wild gardening is based upon a despair of the house and a desire to ignore it. Now that we are beginning to build beautiful houses again, we are beginning also to design formal gardens to suit them; but even those of us who must needs live in ugly houses will do well to make the best of them, as Morris advised. For, after all, even the ugliest house cannot be ignored by those who live in it; and no skill can really make a garden look like a flowery Alpine meadow or a stretch of woodland. In- deed, the uglier the house the more incongruous must be the most plausible imitation of nature, whereas a INTRODUCTION xvii garden of ordered beauty will do much to mitigate the ugliness of any house. But, if we make up our minds for a formal garden, we must understand clearly what are the proper limits of its formality; and, in the first place, we must know that a formal garden does not mean formal flowers. The landscape gardeners tried to imitate nature in their design, and to depart from nature as far as they could in their horticulture. The good formal gar- dener will forget nature altogether when he plans, but when he comes to choose his flowers he will re- member that nature is a better designer of plants than any gardener, though gardeners may sometimes improve upon nature’s designs in detail, and to suit their own purposes. The English idea of a pleasure garden has always been a garden of flowers. We love flowers by instinct, and the return to nature in gar- dening got all its force, not from our desire for a new kind of design, but from our desire to see once more a natural abundance and variety of flowers in our gardens. It is therefore the task of the designer to provide this abundance and variety within the limits of his design. In this respect he will try to outdo nature rather than to ignore her, and he will be eager to learn any lessons that she can teach him. He will place his beds and borders according to a pattern in his own mind, about which nature can teach him little or nothing; but, when he comes to plant them, he will know that nature can teach him a great deal; for wild flowers, in the course of the struggle for life, xvill INTRODUCTION have acquired a natural fitness of combination and arrangement, which art may improve with its greater variety of material, but should not ignore. It used to be the delight of gardeners to ignore this natural fitness. As Ruskin remarked, they would tear house- leeks from their roofs and plant them round their beds. It was their practice to seize on the abnormal- ities of nature and make them the rule in the garden, although such abnormalities are usually the result of adaptation to peculiar conditions and look utterly out of place except in those conditions. Most Cacti, for instance, are desert plants, and may have a beauty of their own when they grow among rocks and sand. They have none at all in a flower-bed. The return to nature has taught us to see the absurdity of carpet bedding and all such misuses of natural materials. It has quickened our sense of the fitness of things, so that the best gardeners now delight in growing plants in conditions that will show off their beauty to the best advantage. It is the business of formal gar- dening, as of every other art, to do this; to make its own design, and at the same time to obey the laws of its material — that is to say, to use its material so that its characteristic beauty may be displayed to the best advantage. To combine these two things, formal beauty of de- sign and a right use of material, is the main difficulty of every art, and it is peculiarly difficult in gardening. There is always a strong naturalistic tendency in the gardener who loves his plants, as in the landscape INTRODUCTION xix painter who loves the country, or the dramatist who loves men and women. The mention of this nat- uralistic tendency makes one think at once of Tue Rock GARDEN, which is the most signal instance of it in modern gar- dening. It must be confessed at once that rock gar- dening, as we all practise it, is inconsistent with all the ideas that have produced formal gardening, and aims at a different kind of pleasure from that which the formal garden gives. A formal garden is a place to live in, whenever our climate allows; but no one would think of living in a rock garden. There are no flat spaces of lawn in it or shady retreats. It is all up and down, and, except for a few narrow and wind- ing paths, all made up of rocks and flowers and shrubs. No one except the rock gardener himself ever stays in it for long. For others it is a sight to be seen, per- haps with interest, perhaps with a polite show of in- terest. If it is very large, very boldly built, and very skilfully cultivated it may possibly have some slight resemblance to an Alpine hollow or slope; but usually it has none at all, and betrays itself at once as a con- trivance for the cultivation of certain plants that will not thrive or will not display their full beauty except in certain special conditions. It is, in fact, a place made for the sake of the plants which are grown in it, whereas the plants in a formal garden are but orna- ments to the general design of the garden. So, if you are a formal gardener on principle, you XX INTRODUCTION cannot defend the rock garden on the same principle; and we may say at once that, if it were possible to have only one kind of garden, the formal garden would be the kind to choose. But luckily that is not so; many different kinds of gardening are possible, and many different kinds of pleasure are to be got from them. The pleasure of the formal garden is the most uni- versal, the most sure, and the most lasting. Any one who knows nothing at all of plants or horticulture can enjoy a formal garden; and if it changes hands its beauty can be easily maintained, since there is a routine of formal gardening which most professional gardeners understand. On the other hand, you must have a peculiar interest and delight in plants for their own sake if you are to take a real pleasure in a rock garden; while the knowledge necessary for the proper cultivation of a rock garden is not usually possessed by professional gardeners, so that when a rock garden changes hands and loses the care and skill of its orig- inal possessor it is apt to run wild and become a mere confusion of coarse-growing plants. But these objec- tions to the rock garden are the very reasons why the true rock gardener takes a peculiar delight in it; and it is a curious fact that every gardener with a real love of his art tends sooner or later to become a rock gardener and to take a greater pleasure in his rock plants than in any others. This may seem both wrong and incomprehensible to those who are not gardeners; but they must remember that the gardener not only takes a pleasure in his flowers when they are grown, INTRODUCTION Xxl he also takes a pleasure in growing them; and there is more pleasure to be got from growing Alpine plants than any others. This is not merely because they are difficult, although in every kind of art and craft there is always a pleasure in overcoming difficulties; it is also because Alpine plants have a peculiar kind of beauty which appeals to the lover of flowers more than the beauty of any other kind of plants. Alpine plants, as every one knows, have adapted ‘themselves to certain abnormal circumstances. They grow in high wind-swept places, often in deep fissures of rock with but little soil, where they enjoy but a short spring and summer, and where they endure for a great part of the year the most extreme cold. In one way they are the hardiest of all plants; but in another they are the most delicate. For in adapting themselves to their life among the snows they have lost much of the power which other plants possess of adaptation to other conditions. And this applies not only to their health, but also to their beauty. If it were possible to grow the higher and more difficult Alpine plants in an ordinary border, they would look quite insignificant among the coarser plants of the lowlands. Even those easier rock plants which will grow readily enough in the border lose a great part of their beauty there, for their home is the rocks, and they seem to have been designed by nature as orna- ments for the rocks alone. Still, we are used to seeing many of them in the border and find them beautiful enough there. No one, however, could think of the XXxil INTRODUCTION higher Alpines, the Androsaces, the smaller Pinks and Primulas, the little encrusted Saxifrages, or the most delicate Campanulas as anything except mountain plants; so much do they seem made for their moun- tain home that one could almost believe they would bring a vision of it to any one who knew them only in captivity; and yet a great part of their beauty comes from the contrast between its delicacy “so still and faint and fearing to be looked upon” and the wild, fierce places in which they grow by nature. But that delicacy is very far from the hectic delicacy of tropical flowers. The higher Alpine plants grow and flower for but a short time of the year, but in that time their life is eager and quick in proportion to its shortness. When the warm spring wind blows and the snows melt they turn from brown to green in a week. Their buds swell so that you can almost see them swelling; and their flowers have a peculiar brightness that seems to tell of the abundance of life packed into so small a compass and enjoyed for so short a season. There is nothing in nature so full of wonder and delight as an Alpine spring. It is the very symbol of all sudden happy changes, the chief theme of mountain folk- song and mountain music; and it is not strange that, as we go to hear the songs of Grieg in a London con- cert-room, so we should wish to see some of the magic of that spring in our lowland gardens. Therefore the rock gardener contrives his little makebelieve. He cannot hope that his small rocks and slopes and val- leys will in themselves have any look of the Alps; but INTRODUCTION XXill they will at any rate serve as a frame not incongruous to the beauty of his Alpine flowers. And his pleasure in rock gardening is enhanced by the fact that the nearer he gets to a natural arrangement of his rocks the more likely are his plants to thrive among them. This kind of natural arrangement is not easy to contrive, and will never come by chance. When peo- ple first began to make rockeries they seem to have had some dim idea of imitating chaos. They bought loads of clinkers, certainly the most chaotic objects ever produced either by nature or art, and they shot them down in confused heaps in parts of the garden most unfavourable to plant life. Among these heaps they planted Ferns and Stonecrops and London pride. Some of these perhaps contrived to live, and did in time conceal some of the desolation of the clinkers; but their survival was a credit to them- selves rather than to those who put them there. When, however, rockeries: first began to be thought of as places for the cultivation of rock plants, there was a violent reaction from this imitation of chaos. Every plant was provided with a square enclosure of stones and a large zinc label, so that even if the plant died, which it often did, it might not lack a monument. This was formal gardening reduced to an absurdity; and those who really loved the beauty of Alpine plants and were eager to grow them soon began to see that the mere proximity of a rock would not cure an Al- pine plant of its home sickness. They set to work to discover what benefit the plant got from its native XXIV INTRODUCTION rocks, and they saw that it was protected by those rocks from extremes both of heat and cold, of drought and moisture. They saw, too, that it could get that protection only from rocks arranged in certain natural ways; and therefore they set to work to imitate such arrangements in their own rock gardens. So the building of rocks became an art and also one of the chief pleasures of rock gardening. It is difficult to convey to any one who has never tried it how great that pleasure can be, and how it increases with experi- ence. There is no one fixed principle of rock build- ing, since natural arrangements of rocks are infinitely diverse, and different plants have adapted them- selves to their diversities. But this fact is what makes the pleasure of the game. The beginner, if he is wise, will build upon a fixed principle. He will arrange most of his rocks so that they run into the ground at an angle of about 45 deg. with the earth’s surface, and so protect the roots of the plants below them from both heat and cold. But as his knowledge increases he will get more of the variety of nature into his build- ing, and put his rocks together so that they provide homes exactly suitable for the more difficult plants which he wishes to grow. He will come to look upon his rockwork as a kind of puzzle to be fitted together so that every interstice will have some peculiar charm for some particular plant; and it will be his delight to find a plant perfectly suited to each interstice. Needless to say, this is not a game that can be played in the ordinary flower border, where there is not much INTRODUCTION XXV variety of condition and where the plants are all con- tented, in reason, with what they get. Those who are quite ignorant of gardening may think a fine flower border more beautiful than any rockwork, and may wonder why any one should be at so much pains to produce an inferior kind of beauty. In answer to them it must be confessed that rock gardening is a kind of game which makes its own difficulties and gets its own pleasures out of them; yet the rock gar- dener will not admit that it produces an inferior kind of beauty, but rather a beauty more subtle and to be appreciated only by those who love plants and study their ways of growth. Plants, he will say, like all other kinds of life, get a great part of their beauty from their adaption to their surroundings, and the more exactly and narrowly they are adapted to their surroundings the greater that beauty will be; while plants that thrive anywhere can have but little of that kind of beauty. Their good nature makes them lose character. They are like men with whom you can do what you choose — useful but uninteresting. Of all plants the higher Alpines are most narrowly adapted to their surroundings; and of all plants they have the most character. Nature seems to have designed them more exactly than other flowers with a more unrelenting pressure of circumstances, so that they have a beauty of proportion not often found in the lowland plants that will adapt their growth to con- ditions so various. There is, we may suppose, an ideal proportion for every plant in all its parts. This XXVi INTRODUCTION ideal proportion is continually forced upon the higher Alpines by the severities of nature, but not upon plants that have a wider range and an easier life. But the peculiar beauty of Alpine plants must explain itself, if it is to be appreciated. You must be able to see from its surroundings how it has come to be what it is; and the rock gardener’s art or game is to contrive those surroundings so that they shall tell their own story. He cannot do this so far as the elements are concerned. He cannot provide winds or snows, but he can provide rocks naturally disposed; and he must do all he can to provide sunshine and fresh air. It is all a game, perhaps; but it is one of the pleasantest and most innocent in the world; and since it is a game played with living things and against the caprices of the weather, there is no end to it, nor is there ever likely to be one. Some plants are easily enough grown to-day that were thought almost impossible twenty years ago; but still there are many, not only from the Alps, but from the Himalayas, the Pyrenees, and the Caucasus, that have not yet been tamed by any skill. Some of these may in time yield up their secret or grow content with our climate. Perhaps some day the blue glory of the Fairy Forget-me-not! will come down from its mountain heights to shine on suburban rockeries. But that will not be in our time. For many years to come lonely triumphs will be possible to every rock gardener; and, indeed, one often sees some difficult plant better grown on a small rockery 1 Myosotis palustris. L. Y. K. INTRODUCTION XXVil than in the most sumptuous rock gardens. Rock gar- dens are to be found everywhere now. They are a part of the return to nature in gardening, and, like other things in that movement, they are sometimes carried to absurd lengths. But, in spite of this, with their ceaseless experiments and with the new sense they bring of the characteristic beauty of plants, they have done much good, not only to the craft of horti- culture, but, in an indirect way, to the art of flower arrangement. They are teaching gardeners not to play tricks with their plants, not to use them like chips in a mosaic. They have, at any rate, put an end to car- pet bedding except in certain public gardens where it is practised as an interesting survival. In the rock garden nature itself forces upon the gardener some con- gruity of arrangement. You cannot mix Hollyhocks with Androsaces; at least, if you do the Androsaces are pretty sure to die. And the gardener who gets a sense of congruity from his rockwork will carry it into other parts of his garden. It is not in the least inconsistent with formal design. Indeed, formal de- sign is quickly spoilt by any incongruity in the ar- rangement of plants; and the best formal borders have a natural look, with all their regularity. Still, with all that can be said for it, rock garden- ing remains a game for the true gardener, and no one should have a rock garden who does not intend to spend time and labour upon it himself. Professional gardeners are an excellent race of men; but most of them are made gardeners, not born, and rock gardens XXViil INTRODUCTION are usually incomprehensible whims to them. They can take a pride in a regiment of calceolarias, but not in a plant that dies if you pull it up by mistake for a weed and makes no show even when it thrives. There is some danger that rock gardens will become fashion- able; and already you will sometimes find strange ac- cumulations of stone in pretentious gardens which are, no doubt, meant to be rock gardens. Indeed, there is a story of a millionaire who built a rock gar- den all of concrete blocks so well fixed together that there was no room at all for plants to grow between them. But, if rock gardening does become fashion- able, it is not likely to remain so for long. A rock garden cannot be bought outright, like a diamond necklace, and kept without further trouble. It is nothing unless its owner loves it and understands it; but, if he does, then he can get as much pleasure out of it as out of any amusement provided by the bounty of nature and the ingenuity of man. This difficulty of the rock garden is only an extreme instance of the difficulties that must be always crop- ping up for every gardener who loves his plants and seeks to provide them with natural conditions, and who also aims at a formal beauty of design. At every point he will have to make some kind of sacrifice or compromise. But that is no reason why he should forgo formal beauty altogether. It is rather a reason why he should try to understand its principles clearly, so that he may know what is the best sacrifice or com- promise to make in each particular case. Unless he INTRODUCTION xxix accepts and understands the principles of formal beauty, he will have no principles to go on except principles of horticulture, which, however excellent they may be, will not help him to solve many of his most difficult problems, will not, for instance, tell him when to leave nature alone and when to subdue it to his own purposes. It is a main principle of formal gardening that a gardener may do anything he chooses with his materials to increase their use or beauty, but that he must not play tricks upon them merely to show how far he can pervert them from the course of nature. Thus, where a tree or shrub is grown for its own sake, to clip it is to spoil its natural beauty for no reason. But, when trees or shrubs are used to make a hedge, clipping increases their beauty as it increases their use. A hedge, properly used, is only a kind of living wall, and you can see at a glance that it is grown not for its own sake, but to serve as a wall. So, whatever treatment makes a better wall of it is justified; and the formal gardener will not try to con- ceal his living walls, but will make them play a part in the beauty of his design. He will see that they are of the finest materials—of yew, or box, or holly, not of privet or laurel; and he will clip them care- fully, so that they grow solid and even. Hedges of this kind, well grown and well placed, will serve as divisions of different parts of the garden, as shelters for the flowers, and also as frames to set off their beauty. Every one must feel the charm of well-kept yew hedges in an old garden, and the secret of that RAY INTRODUCTION charm is that in them nature is subdued to the happy purposes of man. She is always quiet within their en- closure, as the sea is quiet in a harbour; and they are a sign, wherever they are to be found, that order and peace and a delight in beautiful things have been long established there. This is the secret of the charm of formal gardens, and it is a charm that we cannot find in any flowery wilderness, still less in the most cunning imitation of one. So much for the planning of gardens. There re- mains to be considered. THe CHARACTER OF GARDEN FLOWERS, and in particular the principles upon which one should aim at their improvement. The art of improving or changing garden flowers is probably as old as the art of gardening itself. So soon as plants are cultivated many of them become liable to changes and developments of a kind which they seldom experience in a state of nature, because such changes and developments are of little or no use to them in the struggle for life. The gardener’s pur- poses, however, are apt to be different from those of nature, and he makes a different use of that tendency to variation which exists in all plants. Wild plants in favourable conditions, for instance, often show a tendency to double their flowers; but that tendency seldom goes very far, since doubling is rather a hin- drance than a help to plants in the propagation of their species. It is a kind of excess that comes with INTRODUCTION XXxi prosperity, and is apt to be soon checked by the severe laws of life. To the gardener, however, it often seems an excess to be encouraged, and he encourages it by selection on a different principle from that of nature. He may also encourage an increase in the size of the flowers and a greater brightness or variety in their colour by the same means. Such changes or improve- ments have been practised from time immemorial, particularly in the East, so that the origin of some garden flowers, as, for instance, of several kinds of roses, is unknown to us. In the seventeenth century there was a great variety of florists’ flowers, and partic- ularly of carnations, as we can tell from the illustra- tions to Parkinson’s Paradisus. The Dutchmen had then developed Tulips and Hyacinths and Crocuses pretty much as we have them now; and most of them were far removed from the original natural species. But all these developments were produced by simple selection and cultivation. The principles of hybridization were not understood, and the process therefore could not be practised artificially. Now that these principles are understood and can be prac- tised, however empirically and imperfectly, our florists have an enormous advantage over their forefathers; and as their knowledge increases of the conditions most favourable to hybridization, that advantage will grow still greater. Already changes are being worked upon certain plants with wonderful speed. The Pansy, as we have it now, has been developed out of the little wild Pansy (Viola tricolor). The process began about XXXii INTRODUCTION 1813, and by 1830 many varieties approaching the modern Pansy in size and colour and shade were al- ready in existence. But the Viola of gardens, or tufted Pansy, is a creation almost of our own time and a hybrid between the Pansy proper and the Al- pine Viola cornuta. Not much more than a genera- tion ago the Begonia was a plant with insignificant flowers and grown chiefly for its leaves. Now we have Begonias with flowers almost as large as Roses in a great variety of colours. Dahlias have changed the character of their flowers under our eyes. Won- derful things have been done, and are being done, with Larkspurs and Phloxes. There are innumerable new Daffodils, and they increase about every year in size and in brightness and diversity of colour; while there seems to be a promise of new races of Roses utterly surpassing any that we have now both in beauty and in vigour of habit.1 But this new power will be attended with new dangers if it is not exercised with discretion; and already we can see what these dangers are. It is a delightful game to make new flowers, but it is not one that should be played wantonly or blindly. It is unfortunate that hybridization should be first prac- tised systematically in an age of very uncertain taste; for there is a danger lest irreparable harm may be done 1 Certain species of roses recently discovered in China by E. H. Wilson have never been hybridized. When one considers that all the roses we now have are descended from four or five species it is not easy even to imagine the number we may have after bringing in fifteen or twenty new species, crossing those with each other and with those we already know. L. Y. K. INTRODUCTION XXXIil to some of our finest flowers while every one is exult- ing over the improvement worked upon them. At present the florists seem to be working upon no sys- tem, because there is no general standard of taste to impose a system upon them. They believe that every increase in the size of a flower, every change in its colour, is an improvement; and they are often con- firmed in this belief by the awards of flower shows, which, in the provinces at least, are still inclined to favour flowers as little like nature as they can be. Flower shows, indeed, have not had a good effect upon the development of plants, however much they may have improved their culture, since their tendency has been to encourage gardeners to grow plants for their flowers alone. Now a plant intended to be an ornament to a garden ought to be considered as a whole. Its flowers are only a part of its beauty, and it should also have a beauty of leafage, of habit, and of proportion. The flowers of wild plants are often too small, at least to the gardener’s taste, in propor- tion to their leafage and stature; but the flowers of garden plants may easily be too large; and in some cases the florists have already made them so. The modern Begonia, particularly the double Begonia, is an instance in point. The flowers are so enormous that all proportion is lost between them and the plant itself. It seems to be overburdened with them like a woman laden with heavy jewelry. There are other plants of a habit less prostrate by nature which bear the weight of huge flowers still more awkwardly. XXXIV INTRODUCTION There are Carnations and Dahlias and Roses that look like weary Titans unless every flower head is supported with sticks. This defect is not seen in separate blossoms exhibited at a flower show; but it is glaring in a garden, and ought to banish them from all gardens. It is important that we should cultivate in ourselves and in our florists a nice sense of propor- tion in all the parts of a plant. No one can say ex- actly what is the limit of size beyond which the flowers of a particular plant ought not to be developed; but it is easy to see that every plant ought to carry its flowers with ease; and, besides this, the size of the plant itself, the nature of its habit, and the character of its leafage should be considered. A small creeping plant may usually have larger flowers than an erect plant of the same size, because it can carry them more easily; and indeed among mountain plants there are many with flowers very large for their size. Also, a plant with large leaves can endure larger flowers than a plant with small ones; and obviously a large plant can endure larger flowers than a small one. Yet this plain fact is often ignored by florists, who will dwarf a plant without decreasing the size of its flowers and so destroy the greater part of its beauty. The dwarf Snapdragon is a case in point, which looks as much a deformity as a human dwarf; and the dwarf Sweet-pea is not much better. The doubling of flowers is a part of the same ten- dency to grow plants for their flowers alone, which is often carried to excess. Most flowers are more INTRODUCTION XXXV beautiful single than double. But there are excep- tions; and a good many double flowers are, at any rate, more durable and stronger in colour than single ones of the same kind. It would be absurd to object to all double flowers on principle, as, for instance, to double Pinks or Roses or Dahlias; but even these may be easily made too double, so that they look stiff or puddingy; while there are other flowers of great natural beauty of form which are entirely spoilt by being doubled. Among these are nearly all bell- shaped flowers. Yet the florists are always producing double varieties of the beautiful Campanula persici- folia, in which all its grace of form is destroyed with- out any improvement in force of colour. To take other instances, the double Begonia looks as if it had been made by some one who had never seen a real flower. The extra petals of the double Day and Tiger Lilies look like mere growths of disease, and even the double China Asters are usually inferior in beauty to the single flowers of the old Aster sinensis, which has only lately come into our gardens again. It is almost safe to say that we have enough double flowers already, and it is quite certain that florists could do much more useful work in other ways than in doubling any more of them. The colour of flowers is more a matter of individual taste than their proportion or form; but even with regard to colour one cannot doubt that the florists sometimes make mistakes. There is the case of the perennial Larkspur, for instance. The glory of the XXXVI INTRODUCTION Larkspur is its blue colour. In no other genus of easily-grown garden plants is there such a range of blues combined with such purity; and the hybridists have already shown us what a race of Larkspurs might be produced if only they would give all their efforts to combining purity of colour with beauty of form. Unfortunately, it is very easy to obtain double Lark- spurs in which the form of the flowers is spoilt; and also to obtain Larkspurs tinged or freaked with mauve or plum colour. Now mauve is a good enough colour in its way; but we have plenty of mauve flowers. Also the combination of mauve with blue may have a sort of curious discordant beauty; but it is a beauty that one soon tires of; whereas pure blue, deep or pale, is a rare colour in our gardens and one that could never weary any one. No garden flower in existence is more beautiful than the Belladonna Lark- spur with its flowers of a silvery pale blue and no less perfect in form than in colour. But the Bella- donna is smaller and more weakly in constitution than the great hybrid Larkspurs. Already some of these almost rival it in colour, and they might in time surpass it. Already, too, there are some hybrids of a deeper blue almost as fierce as the colour of the Gentians, and these might be common soon, if the florists would set to work to produce only pure blue Larkspurs. But they have now produced so many with mixed colours that it becomes more difficult every year to raise pure blue Larkspurs from seed. The taint of mauve is deep in their blood, and it would INTRODUCTION XXXVil take some time to get rid of it even if every one tried. The Larkspur is a plant of so stately a habit that it would not be easy to make its flowers too large so long as they keep their purity of form. They have already been greatly enlarged, but the largest are often half double and parti-coloured, so that their size is only a thing to wonder at, not to admire. The Larkspur is the worst case that could be found of colour perversion in plants. Most other cases are more disputable. But many people who love strong wholesome colours cannot but think that our Roses are suffering in their colour from the popularity of Tea Roses and hybrid Teas. The colours of most Tea Roses are rather faint and exotic. Their delicacy is pleasing to a timid eye, and there is so much bad colour in our art now that most people’s eyes have grown timid. But there is no need to have a timid eye for flowers. They are not dyed with cheap dyes, or woven of dull shoddy stuff. The brighter they are the better, particularly when they have the texture of Roses. We need more pure pink and deep crimson in our Roses, and not those pinks washed with yellow or those yellows dulled with brown that are so com- mon among the Teas. Roses are not plants of which the ordinary amateur can usually raise new varieties for himself. But there are some plants easily raised from seed and very va- riable, such as Larkspurs and Columbines and Ori- ental Poppies, upon which any amateur with room enough in his garden might try his hand. He can XXXVIil INTRODUCTION hybridize for himself if he will take the trouble, and with the plants just mentioned it is quite easy to do; but in many cases nature will hybridize only too readily for him, so that he has but to save the seed of any variety that pleases him and to go on raising seedlings and pulling up all inferior ones until he gets plants that seem to approach his standard of perfec- tion. If this were done intelligently and systemat- ically by amateurs all over the country, there would soon be a vast improvement in our garden flowers; and no doubt the vagaries of the florists would be checked. They provide novelties because novelties are popular; and they work more or less at random because there is no certain taste to direct them. The remedy is in the hands of amateurs who in some cases can show what they want by producing it for them- selves, and in other cases can enforce a right standard by buying only plants which conform to that stand- ard. We are all too ready to think that every flower must be beautiful, whether produced by nature or by the florist; and we are ready to think that every kind of garden must be beautiful, if only it contains an abundance of flowers. The gardener should grow his flowers well — that goes without saying. But he should choose them upon clear and rational principles of taste, and he should plan the garden, of which they are to be the ornaments, upon the same prin- ciples. STUDIES IN GARDENING BANKS AND SLOPES IN GARDENS EW people who have banks or steep slopes in their gardens know what to do with them. They cannot be turned into ordinary flower beds or borders, because with their sharp drainage they do not afford enough moisture to most plants in the summer; and, if they are covered with grass, the grass is difficult to mow. The usual plan is to plant them anyhow, with shrubs such as laurels, snowberry, or Berberis aquifolia, with a carpeting of ivy or the Rose of Sharon, and having planted them thus to leave them alone. Now, whatever may be said in favour of wild gar- dening in places where the garden can hardly be dis- tinguished from surrounding woodland or meadow, there is nothing to be said for it where it is merely the result of ignorance or indifference. Neglected banks of this kind are constantly to be found in hill- side gardens right in front of the house; and they have scarcely more wild beauty than a disorderly rubbish heap. In such places neglect and untidiness are as discomforting as about the house itself. Yet one often sees a house, neat and trim enough, with all its neatness and trimness spoilt by one of these unkempt wildernesses in front of it. Sometimes there will be an ailing pine or fir tree here and there on the bank, underneath which not even ivy will grow, and 3 4 STUDIES IN GARDENING beyond the shadow of these desolate conifers a stunted thicket of snowberry suckers and sometimes a straggling bush of gorse! or laurustinus; while the ground, if not entirely covered with ivy or Rose of Sharon, will be ornamented here and there with sickly clumps of heather or stray seedlings of the coarsest plants from other parts of the garden. A spectacle of this kind is so common, that, like the ugliness of most houses, it only fills us with a vague kind of discomfort. We, no more than the owners of the neglected bank, attempt to analyse what is wrong. We only feel that we should not like to live in a house with that kind of ugliness about it. Now it is unjust to condemn any system of gar- dening wholesale because of its worst examples; but it is fair to point out that banks treated in this way are the result of the misapplication of the principles of landscape gardening to small gardens. For it is such landscape gardening that has made people in- different to trimness and neatness, or rather has given them an excuse for evading the trouble which is necessary to keep a garden neat and trim. The owners of such banks can always console themselves with the thought that there is no formality about them. But in most cases, no doubt, they make no conscious excuse for their neglect. Bad landscape gardening, the kind of gardening practised by the 1 For Gorse the American gardener may read Forsythia or Spiraea: the Laurustinus is not hardy in the United States except on the Pacific Coast. L. Y. K. BANKS AND SLOPES IN GARDENS 5 speculative builder, which naturally always follows the line of least resistance, is so universal in most suburbs, and even in many country places, that peo- ple take it as a matter of course, and never even ask themselves how their gardens could be bettered. Their eyes have been spoilt, as the eye is spoilt by machine-made ornament; and, even if they always feel a slight melancholy whenever they come in at the garden gate, they do not ask themselves the reason of it. If not actually contented, they are resigned to things as they are, just as they are resigned to the stamped iron ornaments on their fireplaces or the gouty legs of their billiard tables. And, yet, it is worth some trouble and thought to make a garden wear a smiling face, so that it will give pleasure, not only to its owner, but to every passer-by who gets a glimpse of it from the road; and we are all inclined to think well of the owner of a garden which does this, and to thank him for that pleasure. Nor are much trouble and thought, in most cases, necessary. It is very easy to make a steep bank beautiful with flowers and suitable shrubs, espe- cially if it slopes towards the south; and, being so easy, it is strange how seldom it is done, even by people who are ready to spend much labour and money upon other parts of their gardens. Indeed, one often sees the worst examples of neglected banks in gardens with large greenhouses and with gaudy displays of spring and summer bedding. But these are a matter of routine and custom. A steep bank is 6 STUDIES IN GARDENING not supposed to be looked at, however conspicuous it may be. It is regarded as a mere nuisance in the garden; and, consequently, a nuisance and an eye- sore it remains. There are, of course, many people who will not have untidiness of any kind in their gardens, and whose banks are at least tidy. But they usually take a great deal of unnecessary trouble in keeping them so. Either they cover them with grass, or else they hide them with shrubs, probably laurels, which are carefully clipped quite level. Now, this is just as troublesome as grass, and much more irrational. There is no purpose or meaning whatever in a clipped shrubbery, particularly on a steep bank. It does not explain itself, like a hedge; and its only effect is to make the bank look a few feet higher. Laurels suffer more than most shrubs from being clipped, since their leaves are too large to make a close even texture like that of a clipped yew, and they are beautiful only when allowed to blossom and grow tall. There- fore, a clipped bank of laurel is an example of the worst kind of formal gardening, of formality in the treatment of plants, and not in design. There is no such formality in the proper treatment of a steep bank, and much less labour is required for it. No doubt the common neglect or misuse of steep banks and slopes has been caused by the belief that no plants of any value will grow upon them; and this belief arose at a time when our gardens were filled only with bedding plants, few of which, it must BANKS AND SLOPES IN GARDENS 7 be admitted, will flourish upon a steep bank. But we are no longer dependent on bedding plants; and, as a matter of fact, there are many plants of extreme beauty, both in flower and in growth, which ask for nothing better than a steep bank, even with the lightest and sandiest soil, to grow upon. There are so many, indeed, that the gardener can exercise some choice among them; and he will be wise to cover his bank for the most part with plants or shrubs that are evergreen and of a creeping or lowly habit. A bank clothed thus will be interesting, and even beautiful, in the depth of winter, far more so than any border, and it will be full of blossom both in the spring and for a great part of the summer. The plants should be low growing, because steep banks are naturally suited to low-growing plants. Tall shrubs or plants look awkward and out of scale upon them, and find it difficult to get enough root hold to keep them firm against the wind or the wash of the rain. A bank that is to be planted should always be well dug, so that the roots of the plants may be able to strike deep with as little resistance as possible; and, if small rocks can be embedded here and there, they will be of great service to the plants in protecting them from drought, and also to the bank itself, in preventing the soil from washing away from it. If rocks are used, they should be driven downwards into the bank, as in ordinary rockwork, and a plant should be placed just below every rock, so that its roots may have the shelter of the rock. Of course the more rocks 8 STUDIES IN GARDENING that are used on a bank, and the larger, the better. But elaborate rockwork means trouble and expense, and we are proposing to make a bank beautiful with- out much of either. Luckily there are many plants that will flourish upon a bank without any protection of rockwork, provided they do not suffer from drought when first planted. Planting, therefore, should be done in wet weather in early autumn, especially if the soil is very light. It should not be done, in any case, later than October, as many of the most suitable plants are apt to rot off in the winter if disturbed too late. There are no plants which thrive or look better on a bank than the stronger species of wild Pinks. They are evergreen and of a creeping habit. They will endure any amount of drought when once deeply rooted, and, though their flowering period is not very long, their leaves are beautiful at all seasons. The strongest of all is the common Dianthus plumarius, a species of which there are an infinite number of varieties, and which has produced many hybrids with other pinks, particularly with the Cheddar pink (Dianthus caesius). This is much smaller and slower in its growth and rather more delicate in constitution, but it will usually grow on a steep slope looking to the south without much trouble. Other very easily grown pinks in the driest places are D. arenarius and D. petraeus, the English D. deltoides (the maiden pink), D. fragrans (or the plant which usually goes by that name in gardens), and D. monspessulanus. BANKS AND SLOPES IN GARDENS _ 9 All of these may be easily raised from seed, and that is far the best way of getting a large stock. Almost as valuable as the pinks is Aubrietia, of which there are many varieties, and which can be just as easily raised from seed. Aubrietia should always be planted or divided in early autumn, about the beginning of October, as, although one of the easiest of plants, it is apt to resent disturbance at other times. It is scarcely necessary to mention Arabis except to say that the double form lasts much longer than the single in flower and is even more vigorous. A taller growing plant, which combines beautifully with the purple of Aubrietia and the white of Arabis, is the yellow Alyssum saxatile. There is a dwarf form of this, very useful on banks, and also a dwarf variety with pale yellow flowers called A. saxatile citrinum. All of these can be raised from seed, and usually come true. Arenaria montana is a beautiful plant of the pink tribe which flowers soon after Aubrietia. It has white flowers, rather like those of the larger stitch- wort, and the same creeping habit. Of the same family, and a little later in flower, is Gypsophila repens, with its larger variety G. repens monstrosum; plants which will endure any amount of drought. The species is easily raised from seed, but the variety must be propagated by cuttings. Also of the pink family are Saponaria ocymoides and Silene maritima flore pleno; the Saponaria smothered in May with small pink flowers, and for many months afterwards; the Silene flowering rather later with large white blossoms that 10 STUDIES IN GARDENING remind one of those of the pink, Mrs. Sinkins. The Saponaria can be raised from seed. The Silene, being double, cannot, but must be increased by division in early autumn or by cuttings. There are two kinds of thyme that are invaluable for the driest, steepest places — namely, the white and woolly varieties of the wild thyme (Thymus serpyllum albus and T. lanuginosus). A little native plant as low in its growth is Astragalus hypoglottis, with its more beautiful white variety. This is the smallest of all the vetches. It is unfortunately not evergreen, like the Gypsophilas and Silene maritima, but otherwise is admirably suited for steep banks. A plant with beautiful silvery leaves and delicate white flowers which will endure any amount of drought is Tanacetum argenteum (formerly called Achillea), and this looks very well mixed with clumps of thrift, Ar- meria maritima, and especially with the richer coloured thrift known as A. laucheana. Both of these grow about 8 in. high and will afford a little variety to the perfectly prostrate plants. The Helianthemums (sun roses) are little low-growing bushes covered with white, pink, yellow, or red flowers. A variety with golden yellow flowers and glaucous leaves, some- times called H. croceum, makes a beautiful mixture with the common blue flowered Veronica teucrium; and this may also be mixed with the fine yellow vetch (Coronilla cappadocica), which should be carefully planted and not disturbed. Another Veronica less brilliant, but more delicate in its beauty, is V. pec- tinata, with both blue and pink flowers and downy BANKS AND SLOPES IN GARDENS 11 leaves. The creeping Phloxes are not so patient of drought as the other plants here mentioned, but they will grow well on a bank if the soil is fairly rich, or if they are protected by a rock above them; ‘and they are among the most brilliant and beautiful of our spring flowers. Nothing, in fact, can exceed the beauty of large tufts of Phlox Vivid and Phlox Nel- soni, with their mossy habit of growth and their sheets of pink and white flowers. There are some southern plants that do not thrive in the ordinary border, but flourish amazingly on very hot sandy banks looking full south. Among these are Calandrinia umbellata, a little plant of the purslane tribe, with flowers of the most brilliant crim- son magenta colour. This should be raised from seed, and it will usually seed itself freely every year. Cal- lirhoe involucrata is another plant of the same habits; it can be raised from seed to flower the same year, and is of rapid growth, spreading over a great space of ground. It flowers for a long time, and often dies after flowering; but this matters little, as it can be so easily reproduced. Several of the Aethionemas also will grow well on dry sunny banks, particularly A. grandiflorum, A. pulchellum, and A. coridifolium. These are true rock plants, near to candytuft, but with glaucous leaves and delicate pink flowers, and they are the better for a few small rocks about them. They should be planted in spring, or, if raised from spring-sown seed, as soon in the summer as they are fit to move. Many bulbs will thrive on a steep dry slope, partic- 12 STUDIES IN GARDENING ularly the Squills and Chionodoxas, if planted deep, and there is no reason why there should not also be Crocuses, and even the dwarfer Tulips. Bulbs when they die down leave a bare space for most of the summer, and therefore it is well to carpet them with creeping plants that will not interfere with their growth. Nothing is so suitable for the purpose as several species of Stonecrop, in particular Sedum album, which will grow anywhere, and is beautiful in and out of flower. The surface of the bank may also be varied here and there with low-growing shrubs, and these are much better for the purpose than tall plants, as they do not look out of scale with the creeping plants about them. But the shrubs should be chosen with some care, and none of them should be of a straggling habit of growth, or of a kind likely to suffer from drought; for nothing is uglier in any part of the gar- den than a sickly shrub. Luckily there are a good many shrubs suitable for the purpose. The lowest growing of all are some of the prostrate Artemisias and brooms. Of the Artemisias, A. sericea is the best, covering the ground with a carpet of beautiful sil- very leaves and growing at a great pace. It is far more robust than most of the other creeping species. Among the brooms are Cytisus Ardoini, a very dwarf plant with yellow flowers, C. Kewensis, a hybrid also prostrate with paler flowers and rather larger in all its parts, C. Schipkaensis, a small and beautiful white flowered broom, the double form of the native Genista BANKS AND SLOPES IN GARDENS | 13 tinctoria, and also the native Genista pilosa. These are all very small shrubs growing naturally in the driest places. Most of the Cistuses are rather large for planting on banks; but Cistus florentinus, C. lusitanicus, and C. formosus are small enough and may be kept compact by cutting back. Olearia stel- lata (Eurybria gunniana) is the smallest of the Olearias and also may be cut back after flowering with ad- vantage. This and the Cistuses are flowering shrubs of the greatest beauty. There is also a dwarf form of Lavender very suitable for banks, and a prostrate form of the common Rosemary, a most beautiful and valuable shrub. Santolina incana and its smaller variety, incana nana, look their best on banks of the poorest soil, and should be cut down every two years or so in spring.’ All the plants and shrubs which we have mentioned will endure any amount of drought when established, 10f the several species of Cytisus mentioned here C. Schipkaensis may be found in Bailey’s new Cyclopedia under Cytisus No. 2, C. leucanthus Schipkaensis. Cytisus florentinus is possibly a mistake for Genista florida, see under Genista No. 12; there is no Cytisus florentinus known in botan- ical literature. C. lusitanicus is apparently Genista lusitanica, see Genista, suppl. list. C. formosus is possibly Genista formosa which is Cytisus racemosus, see No. 16. C. pilosa is Genista pilosa, see No. 15. Only one of these species is offered in American trade catalogues, C. Schipkaensis. This and Genista pilosa are hardy in the latitude of Boston. The others could probably be grown only in California and the South. The same is true of Olearia stellata which is apparently not sold in the United States. The following may be suggested as American substitutes for the shrubs mentioned above: Cotoneasters in their evergreen dwarf forms, Berberis aquifolia, Ceanothus, Daphne, Evonymus radicans, especially var. vegeta, Rhododendron Wilsonianum punctatum, Andromeda, Leucothoe, Hyperi- cum calycimum, Kalmia angustifolia, Lonicera halliana, Rosa wichuriana, and Xanthoriza. L. Y. K. 14 STUDIES IN GARDENING and they all establish themselves very quickly. Many others might be named that are only a little more impatient of drought, and will grow well enough on a bank of good soil. But we have given enough to show that any bank may be made beautiful, however unpromising it may look, if once it is cleared of rub- bish. It is useless, however, to attempt to grow any- thing on a bank shaded with pine-trees or filled with straggling hungry shrubs. All these must be cleared away before anything can be done with it; and, when it is ready to be planted, the planting should be done with some taste and judgment, the plants being arranged in drifts or masses, each drift at its extremities being interwoven with a drift of another species. The shrubs also should be massed here and there in places where they will seem to grow most naturally, and not aimlessly dotted about. By these means many a bank which is now a mere eyesore might be made the most interesting and beautiful part of the garden, with very little trouble or ex- pense. THE NAMES OF FLOWERS EOPLE who are not gardeners often complain that the names of unfamiliar flowers are apt to be ugly, inappropriate, and difficult to remember. A beautiful pink trumpet-shaped blossom catches their eye and they ask you the name of it. When you tell them Incarvillea Delavayi, they are not satisfied.1. They demand an English name, a name appropriate to its beauties, and one that will call them to mind by its mere look and sound; a name, in fact, like daffodil or honeysuckle. They forget, or they do not know, that all flowers, even those which have the prettiest fancy names, have also business names for purposes of identification, which are often no prettier and no more significant than Incarvillea Delavayi itself. Honeysuckle, for in- stance, when botanists talk about it, becomes Loni- cera. The buttercup is Ranunculus acris and the daisy Bellis perennis. Now honeysuckle was prob- ably called honeysuckle in England long before it got the name of Lonicera; but newly discovered plants do not carry pretty names on collars round their necks. Names have to be invented for them for purposes of identification; names, too, that will serve 1 A new fern at the Holland House Show (London), July, 1916, is thus chris- tened: Polystichum angulare divisilobum plumosum Perry’s No.1. L. Y.K. 15 16 STUDIES IN GARDENING for every language; and so the person who christens a new plant, whether the discoverer or another, does not usually tax his fancy much in doing so. Some- - times he does supply it with a compound descriptive word from the Greek, as in the case of the Chionodoxa, which may, perhaps, in time come to be known as Glory of the Snow or Snow-glory. But he is apt in naming it to pay a compliment to some botanical friend or to commemorate his own achievement; and thus we get names like Brugmansia and Bou- gainvillea, and Tschichatchewia, names which seem to hang like millstones round the necks of their un- fortunate owners. But even these seem worse than they are to our insular prejudice. No doubt Tschi- chatchewia sounds quite simple and pretty to a Pole; and we cannot expect all new plants to bear English- sounding names, unless Englishmen discover them all. Besides, the remedy is in our own hands. Our fathers invented English names for the flowers they knew, and we must do the same for the flowers that were unknown to them, if we dislike the names the botan- ists give them. Until we have done that, we must be content to call a Brugmansia a Brugmansia (or rather a Datura, for that is its present title), however difficult we find it to “tongue” the word. In fact it would be well, perhaps, if all new flowers were named after Poles, so that the difficulty of remembering, spelling, and pronouncing them might act as a spur to the vernacular invention. But, unfortunately, the vernacular invention seems nowadays to be so slug- THE NAMES OF FLOWERS 17 gish that nothing will stimulate it. Eschscholtzia is a word that no one surely would use if he could help it; and yet Eschscholtzias have been known so long that they seem quite old-fashioned flowers; and no one, so far as we know, has even attempted to find a name for them with less than six consonants in a row. The Fuchsia, the Dahlia, and the Wistaria are even more familiar, but they remain still com- memorative of Messrs. Fuchs, Dahl, and Wistar; and the nearest we have got towards Anglicizing them is to mispronounce them. No doubt the chief reason why we do not find Eng- lish names for our new flowers is that we are under no absolute compulsion to do so. They have their botanical names when we first know them, and so we put up with them as a stopgap. Then by use and wont we come to forget that they are stopgaps; and in time Dahlia seems just as fit and proper a name for one plant as Daffodil for another. But, even if English names are invented for new plants, the com- petition of the botanical name makes it difficult for them to get currency. For it must be remembered that the botanical name is universal, and in most cases puts the identity of a plant beyond all doubt, whereas some even of our oldest popular names, such as Gillyflower, Fair Maids of France, and Bachelor’s Buttons, are applied to two or more quite different plants. Also the botanical name identifies the species, which the popular name often fails to do. Thus, if you order a certain plant from a nurseryman, and in 18 STUDIES IN GARDENING doing so call it Zauschneria Californica, the nursery- man will know at once what you mean; whereas, if you call it California Fuchsia, or humming-bird flower, two praiseworthy attempts at an English name, he is pretty sure not to take your meaning. The object of botanical names is scientific precision, which they certainly provide; and so where scientific precision is needed they are usually indispensable. But, for all that, the want of beautiful English names to many beautiful flowers seems a reproach to their beauty, and to stamp them as aliens and not true citizens of our gardens. And the question is, How are we to find beautiful English names for them? The multitude of modern discoveries would make it difficult to keep pace with them, even if we tried; and we certainly do not try very hard. But it must be remembered that the beautiful old names probably took hundreds of years to grow, like other words. They were some- times corruptions of French and Latin names, the corruption no doubt maintaining itself because of some appropriate beauty in its sound or some sug- gestion of a new meaning. Gillyflower, for instance, is said to have been derived from Caryophyllus, Dianthus caryophyllus being the specific name of the carnation, or rather of the pink, from which the carnation has been developed. Gillyflower is a pretty- sounding word, but it has no particular meaning. In the seventeenth century, however, an attempt was made to corrupt the name further into July- flower because the carnation flowers in July. But THE NAMES OF FLOWERS 19 this corruption, for some reason or other, did not stick. The modern name carnation is said to have been originally only an adjective applied to certain Gillyflowers, although Parkinson uses it as an alter- native to Gillyflowers, or, as he calls them, gillo- flowers. No doubt it has ousted Gillyflower because that name was applied to other plants, as, for instance, Wallflowers (which still keep it), Stocks, Rockets, and African Marigolds. The most beautiful names of flowers have grown like folk-songs or ballad poetry; and there is a kind of natural and unconscious poetry in them full of the delight which generations of men have taken in the flowers themselves. But sometimes the same flower will have two different names, one poetic and one expressing the Anglo-Saxon liking for nicknames. Thus Love in a Mist has also the name of Devil in a Bush, and Bleeding Heart (Dicentra) ‘is, or used to be, called Dutchman’s Breeches. We cannot expect to make beautiful names for new flowers off-hand; in such matters the invention of individuals will never equal the invention of genera- tions, nor can it hope to get an immediate currency, especially with the competition of botanical names. Still, it is desirable that some effort_should be made to find English names for our newer flowers, and to use them when found; for there is a danger that we shall grow too content with the botanical names, and apply them even to flowers which have beautiful and well-established English names of their own. Already many good old names have fallen out of use 20 STUDIES IN GARDENING and others seem to be going. There is, for instance, a growing tendency to call perennial Larkspurs Delphi- niums; and the name Columbine, beautiful alike in sound and sense, and one that can be used without any fear of ambiguity, is giving way to Aquilegia. Most people now say Sedum instead of Stonecrop, even in the case of the species to which the English name can be given with perfect propriety, and many call Snapdragons Antirrhinums. Often, of course, a particular species can be indicated only by the bo- tanical name; but that is no reason for using the botanical name where the English name can be used without fear of error. If one wished, for instance, to speak of Antirrhinum asarina, one would have to call it by that name; but Snapdragon will serve for Antirrhinum majus, indeed, it is a more exact term than the generic name of Antirrhinum. The rage for Latin names has gone so far that you will now sometimes see Lilies called Liliums by people who write about them in the gardening papers. Their defence, no doubt, would be that some plants which do not belong to the lily genus are also called lilies; but since we have Primrose and the Rose of Sharon, this would be a reason for calling Roses Rosas; and it is to be hoped that we shall never come to that. But, since there is such a strong tendency towards the unnecessary use of botanical terms, it can be checked only by a conscious effort, and that effort ought to be made. A great deal could be done by writers both of gardening books and in the garden- THE NAMES OF FLOWERS 21 ing papers if they would use English names as much as possible, giving the botanical name where there is any fear of ambiguity, and, even when the bo- tanical name is the one in general use, adding the English name, if one exists. By this means English names in common use might be maintained, some that have fallen out of use might be revived, and some newly invented for new flowers might gain currency. The nurserymen also might help, by always adding English names, where they exist, to the botanical names in their catalogues. Some of them already do this, and in some gardening books a praiseworthy effort is made to keep up the old English names, and even to introduce new ones. Mr. Robinson, for in- stance, in his “English Flower Garden,” always gives an English name when he can, even to newly introduced plants and to different species; sometimes by the mere process of translation, which is often the only one possible. For instance, he calls Sempervivum arenarium the Sand Houseleek; and there is no reason whatever why it should not be generally known by that name, or why Arenaria montana should not be called Mountain Sandwort, or Tigridia the Tiger Flower. When entirely new names have to be in- vented, it is a more difficult matter. People are apt to be shy of using sentimental names, however pretty, unless they are quite familiar, like Forget-me-not; and it is difficult to find a descriptive name for a pretty flower without making it a little sentimental. Noth- ing could be prettier than the name “ Angels’ tears” a2 STUDIES IN GARDENING for Narcissus triandrus albus, but it has not come into general use, although some writers have per- severed with it. No doubt it is too sentimental. Then there is Foam Flower for Tiarella cordifolia, an- other pretty name and quite appropriate, but again, perhaps, rather too sentimental. At any rate, it has not taken root. On the other hand, Rockspray for Cotoneaster is a name so descriptive and so well sound- ing that every one ought to use it; yet it is not used. Other descriptive or half-descriptive names fail from being too cumbrous. Thus we cannot expect that the name “twin-leaved lily of the valley” will stick to Maianthemum bifolium, even though the alternative is no less cumbrous. But it is no use being discouraged by the failure either of good names or of names less good. Only persistency in the use of them will give them a chance, and only by such persistency can it be proved whether or not they deserve to survive. Even a name too sentimental is better than a mere botan- ical term; and, if there is a general tendency to use English names, invention may be quickened, and in some cases alternative names may have to struggle for the mastery. In such a case we should have some approach to natural selection, the best possible means of obtaining good names. In many cases, however, what is required is not invention, but merely revival, and this ought to be far easier; for there are many old names now fallen out of use that ought to take the fancy of any one who hears them, as, for instance, Virgin’s Bower and THE NAMES OF FLOWERS 23 Lady’s Bower for Clematis flammula and C. montana, Cardinal’s Flower for Lobelia cardinalis, Goldilocks for Helichrysum, Lady’s Laces for variegated grass, Pearls of Spain for the white Grape Hyacinth, and Rosaruby for the red Adonis. Many of these names should serve as models for new inventions, partic- ularly in the richness and appropriateness of their sound; for it is sound probably that keeps a name in common speech more than any other quality; and it is only through too much reading that people grow indifferent to the sound of words. Goldilocks and Rosaruby are a delight to the ear. They can only have fallen out of use because they belonged to flowers not much grown nowadays. As for Pearls of Spain, it is a delight both to the ear and to the mind, and worthy of one of the most exquisite of all spring flowers. Even in the naming of florists’ varieties some fancy used to be exercised in the seventeenth century, particularly in the case of carnations. There were red Hulos, and Chrystallines, and Striped Savages, and Cambersines, and Lusty Gallants, and Pale Pageants, and Infantas, and Feathered Tawnies. And there is no reason why florists now should not show a little more spirit and invention in giving names to their novelties. Florists’ varieties do not have botanical names; therefore, the florist has a free choice, and no excuse if his names are meaningless or ugly. Yet they are usually both. What is to be said for the name Blairii 2, given to an excellent old rose, 24 STUDIES IN GARDENING or Gruss an Teplitz, given to an excellent new one? The habit of calling flowers after people is a very dull one and ought to be discouraged. All that can be said for it is that the names of people do not need to be translated. But this would apply also to classical names, which are far less used than they might be. Indeed, they are used scarcely at all. But, even if a pretty florists’ name had to be translated it would not matter much, provided it was short and descrip- tive. Daffodils in this respect are better treated than roses; for instance, Lucifer is a good name for the glowing flower to which it is given; and Sunset is another. But there are some pretty names even among roses, as, for instance, Irish Glory and Irish Modesty for the beautiful Single Teas which have lately come from Ireland. Even humorous names are better than dull ones, and the gardener is to be commended who christened a new cucumber “Ten- der and True,” when he might have called it Lord Kitchener or Sir Henry Campbell-Bannerman. GARDENING IN HEAVY SOILS HE problems of gardening in heavy soils are naturally quite different from those of gar- dening in light soils; for whereas the chief enemy of plants in light soils is drought and heat in summer, their chief enemy in heavy soils is damp and cold in winter. Climate is not the only condition which af- fects the hardiness of plants; soil has also to be con- sidered; and many plants that are hardy on a light sandy soil are not hardy on a stiff clay, although the climate may be no colder. The chief reason of this is that moisture on a stiff clay does not drain away quickly, but remains about the roots and even about the crowns of plants, so that the ground is very cold when it is frozen and, even when it is not frozen, is all through the winter so charged with damp that many plants are liable to rot off in it. It follows from this that drainage is the chief essential to success in a stiff soil; and it is necessary not merely to protect the plants from damp and cold, but also to make the ground fertile, for if the upper layer of the soil is charged with water, air cannot get into it, and with- out air those processes of decomposition which make soil fertile are impossible. No one, therefore, whose garden consists of stiff clay can hope to grow any but the coarsest and strong- 25 26 STUDIES IN GARDENING est plants in it without good drainage. And drainage is not a matter merely of carrying the water away, as it is carried away from the roof of a house; but rather of carrying it down far enough below the plants to prevent their suffering from it in cold and wet winters; for there may come a time, in hot and dry summers, when even in a stiff clay the plants will need all the moisture they can get. Indeed, plants suffer from a prolonged drought in a stiff clay as much as in light sandy soil, or even more, for the clay, if it is in a crude natural state, bakes and cracks, in some places pressing tightly round the roots of the plants, in others exposing them to the full heat of the sun. It follows, therefore, that it is not enough to drain the moisture away from the soil by means of pipes, even if that could be done in a soil which can be deprived of moisture only by the heat of the sun. What is needed is to change the nature of the soil it- self, so that moisture will have a free passage through it. Without such a change, even the use of drainage in the shape of broken bricks, rubble, &c., some feet below the surface is not a complete remedy, for the soil above will still hold a great deal of moisture if its consistency is not altered. The first step towards doing this is to break it up thoroughly by means of deep digging. Deep digging is necessary on a light soil, but it is even more necessary on a heavy one, for it is one of the chief means of introducing air into the ground and thus of making it fertile, and also of enabling the water to find a free passage through it. GARDENING IN HEAVY SOILS 27 But the effects of deep digging upon a stiff clay are only transient, unless the clay is mixed with other matter which will prevent it from clogging with the damp and caking with the heat. It must be made porous by the addition of other more porous sub- stances which will both relieve it of moisture and add to its fertility. Of these the most valuable are tubble and humus — that is to say, soil consisting of decayed vegetable matter and, in particular, leaf mould. There are, of course, many kinds of rubble, but the best of all is mortar rubble, for not only is it very gritty, but it is also full of lime, which in itself is a most valuable form of plant food. Many people use cinders, and these certainly increase the porosity of the soil, but unfortunately they also impoverish it, as they contain no kind of nourishment whatever. Mortar rubble, therefore, should be used, if possible; and it may be very plentifully mixed with a stiff clay soil with the best results for all except the few plants, such as Rhododendrons and Azaleas, and Kalmias, to which lime is poison. Humus does not, of course, increase the porosity of the soil so much as rubble, but it does make it more porous and also warmer, and it is a most valuable and in a stiff clay an almost essential plant food. The rubble and the humus should be mixed together and dug well into the clay, so that the soil for 2 ft. at least is permeated with them. If further drainage is necessary it should con- sist of a foot or so of broken bricks, &c., the larger the better, about 214 ft. below the surface of the 28 STUDIES IN GARDENING soil. To prepare a border in this way entails a good deal of trouble and some expense, but when once it is done the border will need but little attention for some years and the plants will not need to be renewed constantly. It is only in a border so prepared that a great num- ber of plants can be satisfactorily grown on a stiff clay soil, and, further, it is only in such a border that farmyard manure can be employed so as to give the best results. Manure, of course, adds to the fertility of a heavy soil and also, to some extent, increases its porosity; but it is also apt to rot the roots of plants that come in contact with it in cold, wet weather, and to turn sour and breed noxious gases, while its juices can only be thoroughly distributed through clay when it is made porous. Of course, many people will not be at the trouble of preparing a border thus; but even so they may protect their plants from some of the dangers of damp and cold by thorough deep digging, and also by plac- ing some drainage below the roots of particular plants and surrounding these roots with humus and rubble. Thus they will be protected during the winter from the immediate contact of the clay. Many plants will thrive on a stiff clay, which would otherwise damp off in the winter, if they are planted in a border raised half a foot or a foot above the general level of the soil. Such a border is particularly useful for the culture of bulbs, such as Tulips and Daffodils, and of those low-growing plants which thrive by nature GARDENING IN HEAVY SOILS 29 among rocks, such as Aubretia, the creeping Phloxes, and many kinds of Pinks, including Carnations. Such a border is not difficult to make, especially if it is enclosed by fairly large rocks shaped like tiles and driven firmly into the ground; and it is one of the easiest means of providing drainage, especially for shallow-rooting plants. In a light soil it is well to plant, if possible, in the autumn, so that the plants may be thoroughly established before the summer droughts; but in a stiff clay many plants should be planted in the spring, since winter damp is a greater danger to them than summer drought. This applies, perhaps, even to Roses, unless the soil can be thor- oughly prepared for them beforehand, and to all ex- cept the hardiest shrubs. It is true, of course, that with a favourable winter Roses will survive even in the stiffest clay, and that in such a case they will do much better their first summer than if they are planted in the spring; but if the winter is very severe they are likely to go off wholesale. If the gardener likes to take that risk, he can plant in the autumn, but not later than the beginning of November; if he prefers safety, he will plant in early spring, as soon as all danger of severe frosts seems to be over. Most her- baceous plants can be safely planted in the spring, and some, in a stiff clay, can only then be safely planted. Larkspurs and phloxes, for instance, are very apt to go off if planted in autumn.' Even plants 1 Exception must be taken to the application of this statement to American gardens; Phloxes do well in the United States when autumn-planted, Larkspurs also when on well-drained soil. L. Y. K. 30 STUDIES IN GARDENING like Paonies and German Irises, which usually will not flower well the same year if planted in spring, are best so planted in a very stiff clay. As in the case of Roses, they may do nothing the first year, but they are well established before the winter comes. In any case, if autumn planting is done at all with herbaceous plants, it should be done as early as pos- sible, and it can be done earlier in heavy than in light soils, because there is less danger of drought. Speak- ing generally, deep-rooting plants are better moved in autumn and shallow-rooting in spring, as the shal- low-rooters recover most quickly from disturbance. But in a light soil many shallow-rooting plants are best moved in the autumn, as there is no fear of their perishing from winter cold and damp, whereas if moved in spring they may not recover before a long drought begins. Such plants can usually be moved in spring with perfect safety in a stiff soil; whereas a good many deep-rooting plants in such a soil will succumb to winter cold and damp if moved in au- tumn. Speaking generally, again, deep-rooting plants are most suitable to light soils, in which their roots protect them from drought, while shallow-rooting plants do best in heavy soils, where there is usually enough moisture on the surface even in summer to keep their roots cool. But this is only a general rule. Some deep- rooting plants, such as Peeonies, are never so fine as in a stiff soil, and many shallow-rooting plants will not endure the cold and damp of a stiff clay. GARDENING IN HEAVY SOILS 31 Most bulbs, of course, must be planted in the au- tumn even in the stiffest soils, and they should be planted as early as possible, so that they may be able to start into growth before the winter cold begins. This applies particularly to Daffodils, all kinds of Squills, Chionodoxas, Snowdrops, all Lilies that are planted in autumn, and even to Crocuses. It is less important in the case of Tulips, as most of these start into growth later. It is, as a rule, more difficult to grow bulbs well in a heavy than in a light soil, as they are particularly apt to rot off from damp. It is well, therefore, to put some drainage under them, and to surround them with leaf-mould and grit. Particular care should be taken that the soil is pressed close round them, as, if it is not, water will get into the empty spaces and rot them in the winter. This is more difficult to ensure in stiff clay than in a light soil, as the clay after being dug remains in lumps, whereas the light soil crumbles away. Bulbs in a stiff soil should not be planted so deep as in a light one. As bulbs differ very much as to the depth at which they like to be planted, it is impossible to give general rules in this matter; but four inches is quite deep enough for the base of Tulip, Daffodil, or Snowdrop bulbs, while Crocuses can be placed not more than an inch below the surface. There are many plants which thrive in half-shade with a north aspect on light soils but which prefer full sun and a southern aspect on heavy ones. This applies to Ponies, Pansies of all kinds, Phloxes, 32 STUDIES IN GARDENING Michaelmas Daisies, Madonna Lilies, and, indeed, all the Lilies which will do well in stiff soils — Day Lilies (Hemerocallis), Columbines, many species of Campanula, Lilies of the Valley, Violets, Coreopsis, the hardy Cyclamen, Larkspurs, Foxgloves, Doroni- cum, Alstrcemeria, Funkia, Cranesbills, Christmas roses, Rose of Sharon, all the German Irises (though these, indeed, prefer full sun with any soil), Lupins, Mimulus, Bergamot, Forget-me-nots, Anemone japon- ica, Solomon’s seal, Dicentra spectabilis, Polyanthuses, and even Primroses, Spirzeas of all kinds, Meadow Rue, Spiderwort, and Trollius. All these plants will do well in a stiff soil, provided they get plenty of sun and do not suffer too much from stagnant moisture. «In very hot places Anemone coronaria will do better than in light soils, and even Anemone fulgens will thrive if some leaf-mould and lime are mixed with the clay. Hollyhocks also must have a warm place on a stiff soil, and should always be planted in spring. Lark- spurs and Phloxes are never so magnificent as in a stiff soil properly prepared. Pansies, Polyanthuses, Trollius, Day Lilies, and Lilies of the Valley all grow well in a stiff soil if it is also fertile. The Madonna Lily is often at its best in clay if it is protected from stagnant moisture and in the fullest sun. It also likes lime mixed with soil. Of other Lilies, the Tiger Lily, the Orange Lily, Lilium umbellatum, L. elegans, L. Martagon, and L. Pyrenaicum will all grow well in clay; while L. Chalcedonicum, though a capricious plant, is sometimes seen at its best in clay in a hot GARDENING IN HEAVY SOILS 33 place where the soil is impregnated with lime. The magnificent Lilium Szovitzianum is also said to grow well in clay, but it, like L. Chalcedonicum, needs to be thoroughly protected from stagnant moisture.! Among the Narcissi some do much better in clay than others. Speaking generally, the pheasant-eye Nar- cissus (H. poeticus) and those hybrids which are nearest to it do better in a stiff soil than the Trumpet Daffodils. For these latter the soil should be pre- pared with grit and humus. The double form of Narcissus poeticus thrives better in a clay soil than in any other. It is commonly supposed that all roses do best in a clay soil, but this is not the case. Nothing suits most roses so well as a rich loam; and many of the more delicate teas and Chinas are apt to die off in a stiff clay unless it is very carefully prepared. Of all roses hybrid perpetuals do best in a clay soil, and of these the hardier and more vigorous should be chosen. It is certainly true, however, that clay is better suited to roses than to most plants; but the common idea that any rose will thrive in a clay soil, if planted anyhow, often leads to disappointment. The more rich and porous the soil is made the better, and this applies, not only to roses, but to all kinds cf shrubs. Indeed, it is useless to attempt to grow any except the most robust and long-suffering shrubs in 1Some gardeners recommend planting Lilies on the sides instead of up- right, in order to drain the water from their crowns. This is a practical method but in any case the lily should be set on a bed of silver sand for drainage. L. Y. K. 34 STUDIES IN GARDENING a stiff clay without a thorough and deep preparation of the soil. The soil also should be carefully prepared where any annuals are to be sown, for a stiff clay is by nature too hard and rough and uneven, even when thoroughly broken up, for seeds to germinate well in it. Indeed, on clay one seldom sees those self-sown seedlings which are so common in a sandy soil; and even trees repro- duce themselves from seed much more rarely, which is, no doubt, the reason why light soils are apt to be more wooded than heavy ones. Therefore, when seeds are sown out of doors on clay the surface of the soil should not only be very thoroughly broken up, but should be enriched and softened with leaf-mould and grit. It is seldom much use to sow annuals in autumn on clay, though it is the best way of growing many kinds on a light soil. Indeed, all annuals should be sown, even in the spring, some weeks later on clay than on sand. In the case of biennials and perennials many kinds which can be sown in the open ground when it is sandy should be sown in boxes of prepared soil where the natural soil is clay, since not only are they apt to fail to germinate, but they are also liable to be eaten off by slugs while still in a young and tender state. Slugs and snails are perhaps the worst pests of a heavy soil, and there is no means of extir- pating them. They can only be dealt with in detail by killing all that are encountered and by surround- ing the plants for which they have a particular fancy ‘with soot or ashes. Not only is the voracity of slugs, GARDENING IN HEAVY SOILS 35 though vegetarian, comparable with that of sharks and crocodiles when the difference of size is considered, but they have also a horrible epicurism of taste which will not be satisfied by an innocent meal off the leaves of vigorous and full-grown plants. They make for whatever is young and tender, and are happy only when they can kill where they dine. Where they abound, therefore, seedlings should not be exposed to them until they have outgrown their first delicacy.! All these matters make gardening on clay a difficult and troublesome business; and the stiffer the clay the stiffer is the gardener’s task. But we cannot all live on a rich loam of the right consistency. We must take gardening as a game, with different rules in dif- ferent places. Sometimes the rules are easy and sometimes difficult. On a stiff clay they are certainly very difficult. But some people find the most difficult games the most interesting, and the born gardener reveals his genius most when he has to deal with stiff clay or pure sand. 1In the United States snails and slugs are not common. Their counter- part may be said to be the cutworm, whose ravages many American gar- deners know too well. L. Y. K. CAMPANULAS HERE are some flowers which in the most formal garden never lose their wildness or that air of romance which most wild flowers possess. Every Daffodil looks like a meadow flower, and all cam- panulas seem to belong to the mountain-side or the woodland. There is a mysterious charm about all bell-shaped flowers, as if they really had some secret musical purpose; and there seems to be a further mystery in the dim-blue colour of campanula bells. The wild beauty of these plants has been but little touched or altered by the florists, and the reason, no doubt, is that Nature herself has already done nearly all that can be done with them. There are some plants, such as Pansies or Begonias, in which she seems to produce merely possibilities for the gardener to realize. There are others which she herself perfects for the garden, enlarging their flowers until they can scarcely be further enlarged without loss of symmetry, and developing innumerable species infinitely varied in habit and form. This is the case with campanulas. There are some that grow as tall as a man, and some that grow scarcely higher than moss. The flowers of some are bell-shaped, others starry, and others al- most flat like plates. Only in colour do they vary little, being nearly all of a soft-grey blue or purple, 36 CAMPANULAS 37 although there are soft-pink Canterbury-bells and white varieties, either natural or garden, of many species. In some cases the florists have enlarged their flowers, in one or two they have doubled them; they have also produced a certain number of hybrids, but even among the hybrids as many have come by ac- cident as by design. But alJ these are only exceptions; most campanulas are as Nature has made them; and she has produced few flowers with more character and beauty. For garden purposes it is convenient to divide campanulas into classes, the tall kinds of the lowland and the low-growing mountain species, while there are a certain number of intermediate kinds, such as our own English harebells and Campanula car- patica. The taller kinds, naturally, are best suited for the border, and the mountain species for the rock- garden; although several of the latter are so easily grown that they make excellent plants for the front of the border. Most of the border campanulas are woodland or half woodland plants, and, therefore, they like a cool or a shady place, except in a very stiff soil. They are nearly all easily grown, but they pre- fer a rich soil, and many of them will not reveal their full beauty without it. The best known of all cam- panulas is the Canterbury-bell (C. medium), of which it is scarcely necessary to speak except to say that the double and cup and saucer varieties are not nearly so beautiful as those with flowers of a natural and simple form. ‘Two other species are almost as com- mon and, being perennials, are even more useful than 38 STUDIES IN GARDENING the Canterbury-bell — namely, C. latiloba (or grandis) and C. persicifolia. C. latiloba is the easiest grown of the campanulas, thriving in poor soil, provided it is not too hot, and increasing like a weed. It has soft-blue flowers shaped like a plate or a shallow saucer, and there is a white variety which grows stronger than the type. C. persicifolia is, perhaps, the most beautiful of all border campanulas, and one of the few that have been improved by the florists. The type is naturalized in some parts of England, and has bell-shaped flowers of the ordinary cam- panula blue. There is a natural white variety of it, also naturalized. C. p. grandiflora is a variety with much larger flowers and a most beautiful and vigorous plant. It can be obtained with dark-blue, pale-blue, and white flowers. C. persicifolia, like most cam- panulas, can be raised very easily from seed, and the best way to obtain fine forms is to raise a number of seedlings from a good strain of the grandiflora variety and to keep only the finest of these, raising seedlings from them again in due course. C. persicifolia is not a very long-lived plant, and is apt to dwindle and deteriorate after two years or so, so that the stock should be constantly renewed. Several double varie- ties have lately been produced, but in all of them a great part of the peculiar grace of the flower is lost, and there seems to be no reason whatever for their existence. C. latifolia is a fine British species with pale-blue flowers. In rich soil and a cool situation it will grow 5 ft. or more high and seeds itself freely. CAMPANULAS 39 There is a beautiful white variety and a variety called macrantha, a fine plant, but not so stately in habit as the type. C. van Houttei and C. Burghalti are probably hybrids between C. latifolia and some other parent unknown. They are both very beautiful, having large bells much paler in the latter than in the former. They grow only about 2 ft. high. C. lactiflora is another stately bell-flower, growing often 6 ft. in height. Its flowers are small, but very numerous, and of a very pale-blue colour. There is a variety with deeper blue flowers. C. celtidifolia ap- pears to be only a rather inferior variety of the same species. C. lactiflora seeds itself freely, and should be left in the same place for years, as it shows its full beauty only when undisturbed. Campanula pyramidalis is a well-known plant, often grown in pots in greenhouses. It is, however, .. perfectly hardy, though it is apt to deteriorate quickly after the first year’s flowering. It also often grows 6 ft. high and remains in flower for a long time. Al- though such a tall plant, chance seedlings of it will thrive in the fissures of walls, and in such places it often seeds itself profusely. It is best renewed from seed about every two years, and, if the seed is sown early in spring and the plants are well treated, they will flower the next year. There is also a fine white variety and a shorter variety called compacta. C. pyramidalis likes more sun than most of the taller campanulas. Campanula alliariefolia is a handsome plant grow- 40 STUDIES IN GARDENING ing less than 2 ft. high. It has large drooping white bells, and can be easily raised from seed. Campanula urticifolia is usually seen in the white double-flowered variety. This is one of the few cases in which doub- ling improves a campanula, and it is a very pretty plant. C. glomerata is a British species and very easily grown. It is only about a foot high, and the flowers, of a rich violet colour, are crowded together at the top of the stalk. The white variety is very beautiful, but not so vigorous as the type. There is also a new very dwarf form called acaulis, a good plant for the rock garden. C. punctata is another low-growing border plant, with white spotted flowers. It often takes a year or two to establish itself, and then is apt to become a weed. Besides these are two fine hybrids, C. Hendersonii and C. Fergussonii, both of them, perhaps, being crosses between C. carpatica and C. pyramidalis. They are both valuable and distinct border plants growing about 18 in. high. We will pass now to the campanulas of inter- mediate growth, most of them inhabitants of hill countries or Alpine pastures, but most of them also easily grown in the border. The English Harebell, C. rotundifolia, is, of course, both a lowland and a highland plant; and only its commonness prevents it from being a favourite flower in our gardens. The white form is rather rare, though often seen in Derby- shire. It is less vigorous than the type, and often dies if divided. C. Hostii is a variety of C. rotundifolia, and scarcely to be distinguished from it except by CAMPANULAS 41 the eye of the botanist. It is chiefly valuable for its white form, which is much more vigorous than the white harebell proper, and can be divided without fear. There is also a curious and beautiful double variety of C. rotundifolia called C. soldanelloides. This should be grown in some cool part of the rock garden, as it is far less vigorous than C. rotundifolia. Campanula carpatica is a well-known and beautiful plant with large, open, bell-shaped flowers, growing about 9 in. high. There is a white variety, and several other varieties, of which pelviformis is partic- ularly beautiful. C. carpatica is best raised from seed, and the seedlings are apt to vary a good deal in the size of their flowers and also in the depth of their colour. Campanula turbinata is a dwarf variety with flowers very large in proportion to its size, and one of the finest of campanulas for the rock garden. It will not often come true from seed, and therefore should be increased by division in early spring. Campanula mirabilis is a plant from the Caucasus, of which a great deal was made when it first appeared some ten years ago. It is certainly beautiful, being like a very delicate Canterbury- bell, but, as it often takes years before it flowers and appears always to die after flowering, it is not a very valuable garden plant. It can be easily raised from seed, and should be grown in rather poor, stony soil, on the lower slopes of the rock garden. Campanula rhomboidalis is a pretty harebell growing about a foot high and thriving in any border of ordinary soil. 42 STUDIES IN GARDENING It can be easily raised from seed. C. barbata is no doubt the most beautiful of all these intermediate campanulas, perhaps, the most beautiful of all cam- panulas. Unfortunately, it is rather capricious, grow- ing freely and increasing by self-sown seedlings in some places and dwindling away without flowering in others. In Switzerland it is a plant of the Alpine pastures, and more often than not a biennial. It seems to do best in light, rich soil, in a fairly sunny, well-drained place, where the ground is carpeted with other low-growing plants. It can be easily raised from seed, and its beauty is such that no pains should be spared to make it thrive. There are a great many mountain campanulas, some very easy to grow and some difficult, but nearly all both interesting and beautiful plants for the rock garden. The best known of these are C. caespitosa and C. pusilla (or pumila) which may for garden purposes be regarded as the same plant. C. caespitosa is a little harebell only a few inches high, which will grow in a border in light, rich, well-drained soil, but which looks its best and lives longest in long, deep, and narrow pockets in the rock garden. In such places it will thrive in full sun and poor soil, throw- ing out runners wherever it can find space and grow- ing into a plant a foot or more long. The blue flowers vary a good deal in the depth of their colour, and there is a white variety. C. caespitosa can, like all or nearly all the rock campanulas, be increased by cuttings taken when they are just starting into growth CAMPANULAS 43 in the spring. These cuttings will make good flowering plants the same year, if they are stuck in cold frames. But the simpler plan is to raise seedlings, and these, if seed is sown in March or April in a cold frame, will also flower the same year. Hundreds of plants can be quickly raised in this way at the cost of a few pence, and plants raised from seed are the most vigorous. The white variety often comes true from seed. C. caespitosa makes a particularly beautiful contrast with Sedum album, which flowers at the same time. Scarcely less well known, and quite as beautiful, is Campanula muralis (also called Portenschlagiana). This plant, although it will grow in the smallest fis- sures of rock in the hottest sun, will also thrive in rich soil in cool and half shady places. There are two varieties and their naming is rather uncertain. The type appears to be the smaller plant with pale blue flowers, while the variety Bayarica is larger and has deeper and more purple flowers. Both are most valuable plants for the rock garden, particularly for the north side, where they may be mixed with Silene alpestris with beautiful effect. They are very deep- rooting plants and should be left undisturbed as long as possible. They can be increased either by division or by cuttings treated like the cuttings of C. caespitosa. Seed is not very common, and there is, unfortunately, no white variety known. Campanula pulla is a plant with much the same habit of growth as C. caespitosa, but even smaller, and with deeper blue, or rather purple, flowers. It is 44 STUDIES IN GARDENING also rather more delicate, though easily grown in long, narrow pockets of the rock garden and in light rubbly soil where its runners have room to increase. It will thrive either on the north or south side, but should always have a cool root run. It is best moved and divided every two or three years. It can be increased by seed, though this is rather uncertain in germina- tion unless sown as soon as ripe; by cuttings, as in the case of C. caespitosa; or by division. C. Wilsoni is a pretty hybrid between C. pulla and C. carpatica and more vigorous than C. pulla, though of the same habit of growth. There appears also to be one or two other hybrids of C. pulla, such as C. haylodgensis, though these are of uncertain parentage. C. Tommasiniana is another small Bluebell, with long and very narrow pale blue flowers. It has a very delicate beauty, but is quite easy to grow in chinks of the rocks, thriving best in full sun. It must be increased by division or cuttings. Campanula garganica is a small campanula with leaves very like those of C. muralis, but with star- shaped flowers. There appears to be some doubt as to which of two varieties is the type. One of these is more tufted than the other, has shiny green leaves, and blue flowers. The other has leaves more bronze or brown in colour, a more spreading habit of growth, and flowers nearer to purple in their hue. Of this form, which is perhaps the type, there is also a white or almost white variety. Both are very beautiful, and easily grown in narrow chinks of rock or even CAMPANULAS 45 fissures of the wall in full sun. They can be easily raised from seed or cuttings, and should be left un- disturbed when once planted, as they root very deeply. The variety called hirsuta, with downy leaves, is a larger and more vigorous plant altogether, and will thrive on the north or south side of the rock garden. It should be increased by cuttings or division. All the forms of C. garganica are very beautiful, and pecu- liarly well-fitted to the rock garden. C. Waldsteiniana is a very small campanula rather like C. garganica in its flowers, though more upright in growth. It is rather rare, but quite easy to grow in sunny chinks between the rocks. It must be in- creased by cuttings or very careful division. Campanula abietina is a beautiful plant quite easy to grow, but rather a shy bloomer. It is best grown in rather poor light soil and in full sun among the rocks, and should have a top dressing of leaf-mould every spring. It can be readily increased by division, and, indeed, thrives best if divided and given fresh soil every two years or so. Otherwise it is apt to die out. C. abietina is rather taller than most of the rock campanulas, throwing up stalks about 8 in. in height. ; Campanula isophylla and C. fragilis are two beau- tiful prostrate campanulas usually grown in pots; and, indeed, they are too tender to thrive out of doors except in warm places. It is worth while, however, to try them in the warmest part of the rock garden closely packed among the rocks. C. isophylla likes 46 STUDIES IN GARDENING fairly rich soil consisting chiefly of mortar rubble and humus, and it must be watered in hot dry weather. C. fragilis will do best in the narrowest chinks between the rocks in a soil mainly made up of rubble. It can be raised very easily from seed. C. isophylla is best increased by cuttings taken in spring. Both should be protected in winter if they are left out of doors. There are a few campanulas from the high Alps which are difficult to grow. Among them C. Allioni, C. cenisia, C. excisa, C. Elatines, C. lanata, and C. Zoyzii. They are all purely rock plants and should be grown in very narrow chinks of the rocks, in a soil consisting mainly of sand and rubble, with a very little leaf-mould. They are best grown from seed when it can be obtained. C. Allioni spreads by means of runners throwing up little tufts, and should be given some space to increase in. C. cenisia and C. Zoyzii are tiny tufted plants. C. cenisia grows in its native home in masses of broken shale. C. Zoyzii likes a narrow fissure and does well in some gardens. C. excisa is worth attempting, since it has a flower both curious and beautiful and can be readily raised from seed. C. lanata has a yellow flower, and very little appears to be known about its culture in Eng- land. It comes from the Balkans. All the rock campanulas are best disturbed or divided in spring, as some even of the most vigorous of them are apt to die in the winter if they are dis- turbed in autumn. Although most of them like a good deal of sun, they also like a cool place for their CAMPANULAS 47 roots, and, therefore, should be placed so that their roots can run under rocks. The kinds, such as caespi- tosa, pulla, and Allioni, which run under the soil, should be given plenty of room for increase, as other- wise they quickly deteriorate. The more difficult species all like a south-west aspect, but many of the more vigorous kinds, such as caespitosa, garganica hirsuta, turbinata, Wilsonii, and pulla do well on the north side if unshaded, and are most useful plants for this purpose. Muralis, as we have said, will thrive also in half shade. With the Pinks and Saxifrages, Campanulas are the most valuable of all families of plants for the rock garden. THE CULTIVATION OF ALPINE PLANTS HERE is some vagueness in the use of the term Alpine as applied to plants. It never means merely the plants of the Alps. Indeed, the epithet Alpinus is applied botanically to mountain plants from other continents besides Europe. But besides this geographical looseness there is also some uncer- tainty about the character which is implied by the word Alpine. Some people apply it generally to all plants which grow on mountains, however readily they may adapt themselves to the lowlands. Others confine it to those high mountain plants which can only be grown in our gardens in special conditions and with some care and skill. This seems the best use of the word for any one who considers Alpine plants from the point of view of their cultivation, since it is only the more difficult among them that need to be cultivated in a peculiar way. But, even if one confines the term to mountain plants that need special conditions, there still remains the difficulty that such plants vary a good deal in the conditions which they require; and ignorance of this fact causes many failures. Not only do Alpine plants come from many different climates, but even the same range of mountains will usually afford a great diversity of conditions, resulting in an equal diversity in the character and requirements of the plants which 48 CULTIVATION OF ALPINE PLANTS 49 grow upon it. Thus, even in the Swiss Alps, there are some plants that are purely saxatile growing in very narrow and deep fissures or chinks between the rocks, needing hardly any soil for their nourishment and getting all the food and protection they require from the rocks which surround their roots. Plants of this kind are apt to be very deep-rooting, and, when once they have thrust their roots down among the rocks deeply embedded in the soil, they are usually safe against any amount of drought and heat in the summer or moisture and cold in the winter. The more difficult among them need scarcely any soil at all, merely a little grit and rubble to fill up the spaces between the rocks. They will usually thrive on a steep, sloping bank; and there is no need to ar- range the rocks where they grow so as to catch and hold the water on the surface of the soil, as they get all the moisture they need from the rocks about their deeper roots. Most of them like all the sun they can get, and should, therefore, be grown on rock-work facing to the south. Many plants of this kind which can be successfully grown in English rock gardens come from mountains in Asia Minor and other hot countries, so that they sometimes suffer from very sharp frosts, especially if accompanied by cutting winds. They should therefore be grown in sheltered places, and in very hard winters should be protected with a mat or cut heather. Among plants of this deep-rooting purely saxatile character may be men- 1For “cut heather” Americans may read “pine boughs.” L. Y. K. 50 STUDIES IN GARDENING tioned the Aethionemas, some of the more difficult Campanulas, the Acantholimons, the Wahlenbergias (also called Edraianthus), Armeria caespitosa, some of the smaller and more delicate Pinks such as Dian- thus neglectus and D. freynii, Geranium argenteum and G. cinereum, Hypericum repens, H. reptans, and H. coris, Iberis saxatilis, Lychnis lagascae, Phyteuma comosum, Potentilla nitida, Saxifraga longifolia, 5. pyramidalis, and many other saxifrages of the same class, Silene Elizabethae, Antirrhinum asarina, Ero- dium guttatum, and E. chrysanthum. These plants are not all difficult to grow; a good many of them, in- deed, are quite easy; but they all do best, and are safest against the caprices of our climate, when grown in deep and narrow chinks between rocks; and they will all thrive with very little soil. The problem of the cultivation of plants of this kind is, therefore, fairly simple. The main thing is to induce them to root deeply. Until they have done that, they must be protected from drought as a rule; but, when they have done it, they will protect themselves. Most of them will thrust their roots several feet down. The rocks about them, therefore, should be equally deeply embedded in the ground, and the soil should be thor- oughly well drained as far as their roots are likely to descend. It is no use to attempt to grow such plants upon a heavy or damp subsoil with a foot or so of rocks and grit above it. They will thrive until they reach the subsoil, and then their roots will rot away the first winter after they have reached it. CULTIVATION OF ALPINE PLANTS 51 But there are other high mountain plants — and these are often the most difficult to grow — which are not content merely with deep and narrow chinks between the rocks. They are plants which, in their native homes, obtain a continual supply of moisture from the melting snows during their growing and flowering season; and they need, therefore, a supply of moisture, when they are grown in a rock garden, in all hot and dry weather. They also usually need as much sun as they can get; and, since in their native mountains they are at rest and frozen hard for many months of the year, they are apt to suffer very much from the damp of an English (or American) winter, and often require as sharp a drainage as the purely saxatile plants. Plants of this kind often root deeply, but they often also increase by means of runners which travel below the surface of the soil and throw up tufts in all directions. In this case they cannot be grown in very narrow chinks, like the purely saxatile plants, but must be given room enough for increase; and this also makes it difficult to protect them from drought. Gentiana verna is a plant of this kind; and it has got the reputation of being difficult to grow, because many people have treated it as if it were a purely saxatile plant, stuffing it into some narrow chink between the rocks in a place where no moisture will stay on the surface. Gentiana verna is really rather a plant of the Alpine pastures than of the rocks; and it is usually seen on grassy slopes which are watered by the melting snows during its flowering 52 STUDIES IN GARDENING period, and where it can throw out its tufts in all direc- tions. If it is grown on a slope in England (or Amer- ica), however, it is difficult to protect from drought, especially as it needs all the sun it can get. It is best grown, therefore, in a little hollow of the rock garden, which will catch all the rain that falls into it, and where the plant will have plenty of room for increase. Gentiana verna is not difficult to grow when once its needs are understood, because it is not very impatient of moisture in the winter. There must be good drain- age below it; but, if such drainage exists, it can and should be grown in rich soil—a mixture of turfy loam and leaf-mould, for instance, suits it well. But there are other plants which need as much moisture in the summer, but which are so impatient of damp in the winter that they must be provided with a much lighter and poorer soil. It is plants such as these that are particularly difficult to grow; and yet a good many of them can be grown successfully if only the rocks are arranged so as to protect them both from drought in the summer and from damp in the winter. Like Gentiana verna, they must be grown in little hollows among the rocks, but in hollows where the drainage is very sharp. The pockets in which they are planted should not themselves be sloping, but slightly depressed in the middle like a saucer, so as to catch the rain. They should be planted close to a rock arranged so that their roots can run under it and be kept cool by it, but the other rocks should come closer together downwards like the sides of a CULTIVATION OF ALPINE PLANTS 53 pot, so that the earth enclosed by them may remain firm, and so that all rain may run down by the roots of the plant. Alpine plants which increase by underground run- ners, and which are liable to suffer from drought, are much benefited by a top-dressing of silver-sand and leaf-mould when they are just starting into growth in the spring. This top-dressing is peculiarly val- uable — and indeed essential —to all delicate sur- face-rooting plants, as it protects them from drought and gives them just the nourishment they require. It should be applied very carefully and worked in among the growths with the fingers, and may be re- peated later on in the summer if the earlier dressing has washed away. A top-dressing of this kind is a natural remedy, since Alpine plants in their native homes are often subject during all the warm part of the year to a perpetual wash of sand and grit and vegetable matter; and some of them, such as the smaller primulas, have a habit of growing out of the ground, which is no doubt a natural device to protect them from being smothered by the wash of earth. Such plants will soon die if they are not top-dressed. Al- pine plants with very woolly leaves are also the better for a top-dressing of pure grit in the autumn as this absorbs the moisture and prevents their suffering from it. The Fairy Forget-me-not (Eritrichium nanum) is an extreme instance of the plants which need the kind of culture described above. It and a few other plants of the high Alps have never yet, we believe, 54 STUDIES IN GARDENING been successfully cultivated for any length of time in England, and are never likely to be until some new secrets of acclimatization are discovered. But there are other plants with the same kind of requirements, but less exacting, which often fail in English gardens because they are usually treated like the purely saxatile plants and so are apt to suffer from drought in the summer. Among such plants, some of which can be grown easily enough in the manner we have described, are Androsace carmea, A. ciliata, A. villosa, and A. vitaliana (also called Douglasia), Dianthus alpinus, and D. callizonus, Draba Mawii, and D. pyrenaica (also called Petrocallis), Globularia nana, Myosotis rupicola (this plant will thrive in a narrow chink, but needs protection from drought), Polemonium confertum, Omphalodes luciliae (a very capricious plant, which will often thrive on a north slope), Rhododendron chamaecistus (which likes some shade), Saxifraga burseriana, S. apiculata, 8. Gries- bachi, S$. Boydii, 8. squarrosa and S. caesia, and Silene acaulis. Some of these plants are quite easy to grow, as, for instance, Androsace carnea and A. villosa, Polemonium confertum, and the white form P. c. mellitum, Saxifraga apiculata and S. caesia and Silene acaulis. But they are all the better for surface mois- ture, and are apt to perish from drought if grown as purely saxatile plants. There are also many plants which come between the two classes. Many of the Alpine primulas, for instance, are purely saxatile plants in their native mountains, yet are apt to suffer CULTIVATION OF ALPINE PLANTS 55 from drought in England if grown on the south side of the rockery, and tightly packed among the rocks; while, if they are placed on the north side, they often refuse to flower. The best plan with them is to grow them in little hollows on the south side where the rain will not all run away off the surface, and where they can be watered with some effect and get a little shade from the rocks about them. This applies also to Morisia hypogaea, a pretty little tufted cruciferous plant, with yellow flowers that often appear at the end of February and continue for months; also in a less degree to Erodium Reichardii (or Chamaedrioides), a very minute prostrate plant with delicate white flowers, which sometimes suffers from drought if placed on a dry slope; also to Aquilegia pyrenaica, the smallest of the Columbines, and a plant which often suffers from drought in English rock gardens. There are also some larger'plants which need the same kind of treatment such as Daphne Blagayana and Atragene (clematis) alpina. These also like a good deal of sun, and yet will not often endure the dryness of steep slopes in the rock garden. It is easy in most rock gardens that are properly planned and constructed to protect plants from ex- cessive moisture. The real difficulty usually is to protect them from drought and to know how much drought they will endure. On this point only experi- ence can bring certain knowledge; but the gardener can often guess a good deal from the nature of their roots and of their growth. Shallow-rooting plants, 56 STUDIES IN GARDENING for instance, are always likely to suffer from drought, and also plants whose roots are very fine and delicate. The roots of some of the more delicate Alpines are like silk, whereas the roots of plants like the Aethione- mas, which will endure any amount of drought, are thick and strong. Further, it is easy to see that a plant which grows like a tree from a single trunk or crown will need a much smaller surface of soil in which to grow to its full size than a plant which spreads in a mossy tuft or by means of runners under the soil. Some of the plants which increase by means of runners need only a very narrow crevice or pocket between the rocks in which to spread, but it must be long as well as narrow. Such a plant, for instance, as Cam- panula pulla will thrive in a long slit full of leaf-mould and rubble, but if confined by rocks on all sides it will soon die out. All Alpine plants must be kept quite free from drip, and, therefore, no rocks must overhang them. The plants of the higher Swiss Alps usually prefer a south-west or a south-east aspect, those which suffer from drought or which flower very early doing best when they look towards the south- west. The Alpines from hot climates, such as the Aethionemas, the Wahlenbergias (except W. hedera- cea, which needs moisture and half shade), and the Onosmas should be placed on a slope looking full south. All Alpines when planted should be pressed very tightly into the ground. There is no detail in their culture more important than this; and after a sharp frost they should be examined to see whether CULTIVATION OF ALPINE PLANTS 57 the frost has lifted them at all out of the ground. If it has, they should be pressed back into their places. The best time of planting for most of the more dif- ficult Alpines is the early spring, or, if they are raised from seed, as soon in the summer as they are large enough to plant out. It is risky, of course, to plant out small seedlings in May or June; but, if they can be protected from drought, they will be strong plants by the autumn; and, though a few may succumb to the winter, the survivors will be much more healthy than if they had been enervated by the protection of a cold frame. For the higher Alpines all naturally like as much fresh air as they can get, and a winter in a cold frame will often undermine their constitu- tions. Whenever it can be done, the best as well as the cheapest way of obtaining Alpine plants is to raise them from seed. Most of them come readily from seed if it is sown as soon as ripe, and this should al- ways be done, if possible. When the seed cannot be obtained as soon as it is ripe, it should be sown about the end of March. The seed of the rarer and more delicate plants is best sown in shallow earthenware pans with, of course, a hole for drainage at the bot- tom. The soil should consist of a mixture of sand or grit and fine vegetable soil. The pans should be very sharply drained with a mixture of crocks or rubble filling about half the pan. The most impor- tant point in the raising of seedlings is to keep the soil always fairly moist; and it is a great help towards 58 STUDIES IN GARDENING this to cover the pan with a sheet of glass to prevent evaporation. This sheet must be removed as soon as there is any danger of its drawing the seedlings. Watering must always be done with a very fine rose, and care must be taken not to wash the seed all to the edges of the pan. To avoid this, and to keep the pans in an even state of moisture, some gardeners place them in troughs or basins with about two inches of water in them. Then the water gets into the pans through the hole at the bottom and keeps the soil always fairly moist. Where seed is sown of very rare or delicate plants, it is well to follow this plan. The seed of some Alpines, as, for instance, of the Saxifrages and some Campanulas, is almost as fine as dust. When such very small seed is sown it should be mixed with silver sand so that it may not be sown too thick, and should be covered only with the slight- est possible layer of the same silver sand. When the seedlings are up they must be protected from the hot sun, but must have plenty of light and air. It is impossible to give precise general directions as to the best soil for Alpines, as they vary a good deal in their requirements. Some, for instance, need lime, and to some it is poison. It is much to be de- sired that some one should make a trustworthy test of the lime haters and lime lovers, based upon ob- servation and experiment in an English garden. The lists which have hitherto been made are usually im- perfect and often erroneous. Most Alpine plants, however, do not dislike lime, and a great many are CULTIVATION OF ALPINE PLANTS 59 the better for it. The best form in which it can be given to them by those whose rockwork does not consist of limestone is mortar rubble; and a mixture of one part mortar rubble, both grit and lumps, with one part leaf mould or other thoroughly decayed vegetable matter, and one part fibrous loam will suit the great majority of Alpine plants thoroughly. In the case of those which dislike lime, lumps and grit of sandstone should be substituted for the mortar tubble. Speaking generally, one may say that the more difficult an Alpine plant is to grow the poorer should be the soil in which it is planted. But such plants, if planted in fine sand, would suffer much from drought. They need a soil consisting more than half of small lumps of rubble or rock, the rest being mainly grit, with a very little leaf mould. The spe- cially prepared soil should not be less than a foot, or, in the case of deep-rooting plants, two feet deep, and little pieces of rock or rubble should be placed here and there on the surface. All these precautions sound very elaborate and troublesome; but the gar- dener who has learned to take a delight in Alpine plants delights also in taking pains with them. Al- pine gardening is a game, and all good games are difficult to excel in. COLUMBINES HE Columbine is a very old English flower; indeed, Aquilegia vulgaris, the common colum- bine, with short-spurred flowers of a dull blue or pur- ple colour, grows wild in parts of England, and may be indigenous. This common columbine has always been a favourite with painters, because of its beauty of form. There are columbines in Titian’s ‘‘Bacchus and Ariadne,” and Diirer drew them with obvious delight. They are a favourite flower in Italian em- broideries; and Parkinson, in the seventeenth cen- tury says that there are many sorts, “‘as well differing in form as colour of the flowers, and of them both single and double carefully noursed up in our gardens for the delight both of their forme and colours.” Some, he says, “are wholly white, some of a blue or violet colour, others of a blush or flesh colour, or deep or pale red, or of a dead purple, or dead murrey colour, as nature listeth to shew itself.” Among the double columbines, some he says, are “party-coloured blue and white and spotted very variably.” He enumerates five varieties, one being the common single columbine and the others merely double forms of it. One of them, which he calls the rose or star columbine, and which has no spurs at all, but all its petals arranged “like unto a small thick double rose laid open or a 60 COLUMBINES 61 spread marigold,” has been lately revived as a novelty, and is certainly both a curious and a pretty flower. But the columbine in its finer forms is a modern plant, and one which may still be much improved. The beautiful long-spurred species from North Amer- ica and Siberia were unknown to Parkinson, and most of them were introduced into our gardens in the nineteenth century. They excel the common colum- bine both in beauty of form and in variety and purity of colour. They are inferior to it only in vigour; and, luckily, this defect has been lessened and may in time be entirely removed by hybridization; for there is no plant which hybridizes more readily than the columbine. Indeed, it hybridizes too readily, so that, unless a particular species is kept far apart from others, there is no telling what its offspring will be like. But this is a fault on the right side; for, although one may be disappointed with many seed~- ling columbines. grossly inferior to a beautiful parent, yet there is always a good chance that some will be superior; and the ordinary amateur, by merely saving seed from the best varieties and without any skill in hybridization, may in a few years obtain a splendid strain of columbines. Indeed, he may, if he cares to give up a good-sized plot of ground to their culture and if he selects his seed judiciously, obtain a race of plants surpassing most of those sold by the florists. For the beautiful long-spurred hybrids now on the market are too apt to have the rather delicate con- stitution of Aquilegia coerulea, and others of their 62 STUDIES IN GARDENING North American parents. The amateur should aim at obtaining plants with the vigour of growth of Aquilegia vulgaris and the beauty of flower of the long-spurred species. The best way of doing this is to plant some of the better forms of Aquilegia vul- garis among the long-spurred species. The result will be, no doubt, that many inferior seedlings will be obtained, which should be destroyed as soon as they betray their inferiority; but there will also probably be some splendid plants with the virtues both of Aquilegia vulgaris and of the long-spurred species, plants growing 3 ft. or more high and with multitudes of large blossoms, blue and white, pink and white, pink and cream, purple and white, purple and cream, and red and yellow. From these alone should seed be saved, and they should, if possible, be isolated from inferior varieties. This kind of selection may be carried on indefinitely, and, if so carried on, ought to produce results beyond any yet obtained. There are now a good many species of columbine which can be cultivated in our gardens, and an infinite number of varieties of these species and of hybrids. The varieties, for instance, of Aquilegia vulgaris are quite numerous. There is a fine white variety with larger flowers than the type, which is, perhaps, the most vigorous and easily grown of all columbines. It is, however, a dangerous plant for those who wish to obtain a fine strain of long-spurred hybrids, since it intermarries profusely with all columbines grown anywhere near it, and the offspring are apt to be an COLUMBINES 63 exact likeness of the white parent, no matter what the form or the colours of the other parent may have been. There is also a very pretty marbled blue and white variety of Aquilegia vulgaris, no doubt that which Parkinson speaks of as party-coloured blue and white and spotted very variably. There is a dwarf form with dark blue double flowers, a variety with leaves mottled with yellow, and one called Witt- manniana with purple and white flowers. The double varieties are sometimes neat and curious, but not so beautiful in form as the single. The species which has been most valuable in hybrid- izing is Aquilegia caerulea, a most beautiful plant from the Rocky Mountains, with large blue and white flowers and very long spurs. It only grows about a foot high, and is more delicate both in appearance and in constitution than most columbines. It does not usually flourish for very long in our gardens, and often begins to dwindle away after flowering well for two years. Luckily, it can be raised very easily from seed, although it is sometimes rather difficult to obtain a strain of seed that comes true. It is said, indeed, that seed always should come from its native home, and some seedsmen sell seed directly imported. The seed should be sown in spring, so that the plants may be strong enough to plant out in their permanent homes in early autumn. If they are planted out late, they often succumb to our winters. Where the soil is heavy and cold, they should be planted out in spring. Aquilegia caerulea likes a light, rich soil with 64 STUDIES IN GARDENING plenty of vegetable matter in it, and a fairly cool place. It is an excellent plant for the north side of a large rock garden. There is a rare white form, and also a yellow one which often appears in a batch of seedlings, but is inferior to the type. Aquilegia canadensis has light scarlet and yellow flowers, long-spurred, but smaller than those of A. caerulea. It has also a stronger constitution, and will flower well in our gardens for some years. Aqui- legia chrysantha is another long-spurred species from North America, with soft yellow flowers. It is a very vigorous species, almost as vigorous as A. vulgaris; and there are several varieties of it, including a double one. It deserves a place in every garden. Aquilegia californica is yellow and orange, and also a vigorous tall-growing plant. It has produced several hybrids, some superior to both species. Aquilegia Skinneri, a species from Central America, is also red and yellow, and a very bright-coloured flower. It has been used a good deal in hybridization; the hybrids with A. vulgaris are more vigorous than the species, and very various in colour and form. A. Skinneri itself, coming from a hot climate, is not very vigorous in our gar- dens, particularly in a heavy or cold soil. Aquilegia Jaeschkanii is a hybrid, also with yellow and red flowers. There are several species of columbines from Si- beria; but the only one well known is Aquilegia glan- dulosa. This resembles Aquilegia caerulea in colour and in the delicacy of its beauty; but it is more com- COLUMBINES 65 pact and upright in growth, its spurs are rather shorter and its flowers not so widely opened. Its leaves are even more delicately cut, and it flowers some weeks earlier. Besides being one of the most beautiful of all columbines, it is unfortunately one of the few that are difficult to grow, often dying out quickly in Eng- lish! gardens, and sometimes refusing to flower at all. It must never be disturbed while at rest, but should be moved, if at all, after it has flowered. It is best grown from seed sown as soon as ripe or in spring; and the seedlings should be placed in their permanent homes as soon as they are large enough to be moved; or, if they are not large enough till late in the year, they should be left till the spring, and wintered in a cold frame. There is still a good deal of uncertainty about the conditions which suit Aquilegia glandulosa best, as it is a most capricious plant. But it seems to prefer a light soil enriched with humus and a rather cool situation. Drought will often kill it off quickly. It should have a westerly or north- westerly aspect, as the flower-buds form very early and are apt to be withered up by the morning sun, when it follows a sharp frost. It is a plant well worth trying on sheltered north-westerly slopes of the rock garden; and it may be that a dash of lime in the soil will assist its growth. Some people say that it likes a heavily manured soil; but manure is probably more 1May and June in the United States. A. glandulosa, according to Bailey, is likely to flower only two or three years, and should be treated asan annual. L. Y. K. 66 STUDIES IN GARDENING useful to it as a protection against drought than a nourishment, and should be placed well below the roots, or used as a top-dressing in hot weather, if ap- plied at all. At any rate, a plant so beautiful is worth some trouble. Aquilegia Stuartii is a hybrid between A. glandulosa and A. vulgaris Wittmanniana. It is, perhaps, the most beautiful of all columbines, being in appearance simply a finer variety of A. glandulosa. It is also capricious. It appears to do better in Scot- land than in England; and the late Dr. Stuart, who raised it, seems to have had little difficulty with it. It should be cultivated in the same way as A. glan- dulosa, but should be increased by division, as seed- lings seldom come true; and division should be done very carefully with a sharp knife after the plants have flowered. A. Stuartii is a plant which appeared to be almost extinct a few years ago; but in the last year or so some very fine forms of it have been raised, forms surpassing in beauty any other columbines; and it would be well if further experiments were made in hybridizing A. glandulosa with other varieties of A. vulgaris. In the case of A. Stuartii, we believe, the pollen of A. glandulosa was used. There seems to be no reason why plants should not in time be pro- duced with the delicate beauty of A. glandulosa and the vigour of A. vulgaris, and also with some variety of colour. Aquilegia alpina is a plant which is very seldom seen true in English gardens, and which ap- pears to lose a great deal of its beauty in captivity. The true species has large blue flowers and grows less COLUMBINES 67 than a foot high, and there is a variety with white and blue flowers more beautiful even than this type. Aquilegia pyrenaica is the smallest of all columbines and a beautiful plant for the rock garden. It grows about half a foot high, and has soft blue flowers with bright golden anthers. The foliage is almost as delicate as that of a maidenhair fern. This, again, is a plant which is seldom seen true in English gardens. Most nurserymen sell for it a fine dwarf variety of A. vulgaris flowering very early, whereas A. pyrenaica is a per- fectly distinct plant and the latest flowering of all columbines. It seems to be difficult to raise from seed, unless the seed is sown when just ripe; but it is not difficult to grow in a cool part of the rock gar- den in light soil with a good deal of leaf-mould. It does not always ripen seed in England. There are a good many other species of columbines; but we have mentioned most of those which are most distinct and beautiful. Columbines, but for a few exceptions, are easily grown in most English gardens; and the North American species, which do not last many years, are probably not true perennials in their own country. Indeed, all columbines are usually at their best in the first or second year of flowering, and should be frequently renewed from seed. Luckily they are among the easiest of plants to raise from seed, and many kinds will reproduce themselves freely, especially in light soil. The seed may be sown as soon as ripe, in which case many of the seedlings will flower the next year; or else in May, when if well treated 68 STUDIES IN GARDENING the seedlings are sure to flower the next year. The safest plan is to sow the seed in boxes in a soil made light and rich with leaf-mould. The seed usually takes some weeks to germinate; and the seedlings should be kept moist and lightly shaded, and planted out as soon as they are large enough. If plants are bought, they can be planted in early autumn or in spring. In a light soil they are best planted in autumn. Columbines can also be increased by division, but this must be carefully done with a sharp knife; and divided plants are seldom so vigorous as seedlings. The short-lived North American species, such as Aquilegia caerulea, are not worth dividing and should always be raised from seed. Columbines like a cool place, particularly in a light soil, and many of the more vigorous kinds grow well under the shade of trees. They are seen at their best, however, in a cool half-shaded border well enriched with manure and humus. In such conditions some of the most vigorous hybrids will grow to a great size and bear hundreds of blossoms for several years. These hybrids, though they may not have all the delicate beauty of Aquilegia glandulosa or Stuartii or caerulea, are better worth growing for the ordinary gardener, as there is no difficulty in their culture, and they are infinitely varied in the colour and form of their flowers and in their foliage. They are, indeed, among the most beautiful of all garden plants; and, as we have said, there seems to be no reason why they should not be made still more beautiful. Nor is there any reason COLUMBINES 69 to fear lest their flowers should be made too large; for the best hybrids have a growth and leafage vigorous in proportion to the size of their flowers, and double columbines, luckily, are quite out of fashion, being found usually only among the varieties of Aquilegia vulgaris. In fact the columbine is a flower of the future even more than of the present. APRIL NOTES IN THE GARDEN? HIS year we have had some of the wild capri- cious glories of a mountain spring; no weeks of dull east wind to keep the colour out of the sky and the early flowers; but first of all continuous sun- shine all day with hoar frosts at night, and then tor- rents of rain, and one night a fierce snowstorm fol- lowed by a day of showers and warm sunlight. That was a day, indeed, that reminded one of a Swiss April, and one almost expected to see the gentians shining blue through the melting snow on the hillsides. Snow showers of this kind do little harm if unaccompanied by frost, and if no spell of east wind follows them. More harm was done by the earlier alternations of bright sunlight and frost; but even these came too early to be really disastrous. They caused the blue flowers of spring, the Chionodoxas and the first Squills, to fade quickly, and they injured the flowers of the early Daffodils and Irises. They also stunted the stalks 1 The reader should remember that for gardens in the latitude of Boston, at least one month’s difference must be allowed for blooming-period of most of the subjects named in this chapter. Tulip Kaufmanniana for in- stance, in the more northern parts of the United States seldom appears before early April; and the “early April tulips” (presumably the single and double florists’ varieties) need not be looked for here until late April or early May. ‘This chapter therefore is somewhat inapplicable to the Amer- ican climate. For its general interest and beauty it could not, however, be left out. L. Y. K. 70 APRIL NOTES IN THE GARDEN 71 of the April Tulips; but these are now lengthening rapidly with the rain, and everything promises well, if only we can now have some sunshine to warm the sodden ground. The winter was unusually trying for delicate plants, since the warmth of the earlier months forced them into growth, and then, when they had forgotten that there was such a thing as winter, there came a bitter spell in February, with not only frost, but cutting north-east winds. These do more harm than the frosts themselves, particularly to shrubs that are not quite hardy, and even to shrubs that will endure any amount of frost at the roots. Of twelve plants of Lithospermum prostratum, planted on the north-western slope of a rock garden, seven that were sheltered by rocks from the north-east wind are scath- less; the other five, unsheltered, had nearly all their branches killed and are now only just beginning to sprout from the stock. The shelter was only slight, a rock rising a few inches above the soil, on the north- east side of the plants, but it was sufficient to protect them, and they will be covered with blossom in a few weeks, while the others will take months to recover. Thus it is that the gardener learns hard lessons from adversity. Lithospermum prostratum is often said to be a capricious plant. What it needs is protection from north-east winds, rocks to keep its roots cool if it is in a hot soil or situation, and a light rich soil quite free from lime. Then it will flourish and prove itself to be the finest of all rock plants. The rock garden is already full of things to see. 72 STUDIES IN GARDENING The first irises are over; but Iris orchioides is out, rather late perhaps, since it was planted only last year; and so is its cousin, Iris sindjarensis, and the yet more beautiful Iris Willmottiana. Narcissus nanus is in full blossom on a northern slope, making a vivid contrast with the blue Scilla sibirica. This is the most useful of all, perhaps, of the small rock narcissi. It is larger than Narcissus minimus and flowers later, but it has a more graceful habit of growth, and it is not too large for the smallest rockery. It has not the delicate beauty of Narcissus triandus albus, but it is far easier to grow; and in a light sandy soil on a north- ern slope it increases in numbers and in beauty from year to year. Unfortunately it is rather scarce, and many nurserymen sell N. lobularis under its name. N. lobularis is a pretty daffodil, but much larger, almost as large, indeed, as the English wild daffodil, and it is better suited to the grass than to a small rock garden. Narcissus cyclamineus, another rock daffodil of great beauty, is going over. It likes more shade than N. nanus, and, provided it is in shade, will thrive even on a dry rooty bank. It does not die out, like some small daffodils, but endures as well as N. nanus. N. minor is said to be superior to N. nanus, but there is not much difference between them, and N. minor is more expensive. This spring of Alpine weather has favoured the rapid growth of Alpine plants, which is often checked and stunted by our March and April east winds. No amount of experience can abate one’s wonder at APRIL NOTES IN THE GARDEN 73 the swiftness with which plants that seem to be dead one week are in full leaf and even in bud a fortnight later. The Aethionemas, for instance, were all cut back by the bitter wind of February, after keeping their leaves fresh and green until then. Their branches seemed to be quite dead, and one could not but fear lest their roots were dead too. But then, one day, all those withered branches were covered with little green tufts, and a few days later with little green leaves, and then, as the tufts opened, there were pink buds in the heart of them; and now, if we have warm weather and sunshine, Aethionema coridifolium and A. pulchellum will begin to flower in a few weeks. No plant is more rapid in throwing up its flowering stalks than the little biennial Androsace coronopifolia. It is best to sow this plant where it is to flower; and even then it often seems to pine through our winters. But with the first warm weather slender stalks rise from the tufts as they change from bronze to green, and now these stalks have a starry crown of white flowers that will continue for several months. An- drosace lactea is a perennial with much the same habit of growth and with flowers of even more delicate beauty, which is now in full bud after seeming to resent the freaks of an English winter as much as A. coronopifolia. Androsace carnea is in flower with blossoms of delicate pink, and is sending out green shoots in all directions among the leaf-mould with which it has been dressed. Nearly all delicate Alpines need to be dressed with leaf-mould when they start 74 STUDIES IN GARDENING into growth in the spring, and many will shrivel up and die when the east winds blow for want of it. Gen- tiana verna and Dianthus alpinus are now throwing out little shoots, just like Androsace verna, and but for the leaf-mould they would probably have made no growth at all. Primula nivalis is in full bloom, and is certainly the best of the Alpine primulas, flowering more freely than any others, and surpassing them all in the beauty of its milk white blossoms. Though it looks to be the most Alpine of flowers, it is really a garden plant, being, we believe, a white form of Primula pubescens. It likes a westerly or north-westerly aspect, and is quite easy to grow even on level ground in light rich soil, but it shows its true beauty only among the rocks. It does not seem to suffer at all from our win- ters, and may be safely planted in early autumn. The mountain Tulips are, some of them, in flower, some in full bud, and some already over. Tulipa Kaufmanniana is really large enough for a border plant; but most people grow it on the rockery because it probably needs sharp drainage. It was introduced only a few years ago, and is almost the earliest to flower and the most beautiful of all Tulips. It is now over, but in the middle of March its blossoms began to open, at first creamy white and then flushed with pink on the outside, while the inside has a golden centre like that of a water-lily. It suffers little from any caprices of the weather, and its great blossoms, in their last glory, looked strange as they opened above APRIL NOTES IN THE GARDEN 75 the snow-covered ground last Sunday morning. Tulipa biflora, a beautiful little species, with several white blossoms on a stalk, is also in flower now. There ap- pears to be a dwarfer variety of this, called Afghanica, which is an excellent plant for the rock garden and very easy to grow, increasing in ordinary well-drained soil. Tulipa lownei, a dwarf Tulip with delicate pink blossoms, is passing over, and so is T. pulchella, a pretty red Tulip marked inside like a Calochortus. These are apt to suffer and even to die under severe frosts in March, unless grown in a warm protected situation. Tulipa Batalinii and T. linifolia come late enough to be safe usually from such dangers — they will not flower for some weeks yet — and they are the most beautiful, perhaps, of all the small mountain Tulips, the first having creamy yellow flowers edged with a thread of crimson, the second being all of a scarlet that seems to glow with its own fire. Both have leaves that spread out prostrate on the ground, and are curiously crinkled. T. linifolia is supposed to be capricious; but it is fairly sure to succeed on a southern bank in arubbly soil. T. batalinii is as easily grown as most Tulips. They both look their best rising through a carpet of some close-growing stone- crop such as Sedum glaucum, whose roots are too shallow to interfere with the bulbs, and whose leaves are not thick enough to prevent them from ripening well in the summer. The Aubrietias are fast coming into full flower. Such excellent strains of seed are now sold that it is 76 STUDIES IN GARDENING scarcely worth while to buy the named varieties, many of which differ but little from each other. A packet of seed selected from the newer sorts will usually pro- duce plants of all sorts of colours, from deep purple through pale purple to pink and almost deep crim- son. The plants vary in quality of course from seed, some having small and washy-coloured flowers; but these can be dug up if the seedlings are planted fairly close the first year, and the better plants will soon cover the blank spaces. No plant is more easily raised from seed than Aubrietia. If it is sown in boxes in April, hundreds of good-sized plants will be ready to plant out in the autumn. When the plants grow straggly they should be cut back, and they will spring up with renewed vigour. The spring Phloxes are just coming into bloom. These beautiful plants are still much less grown than they should be, although they are most of them very easy to manage. Of Phlox subulata there are now many varieties, some with long trailing branches, some closely tufted. These latter are apt to be a little more difficult than the former. Phlox Nelsoni, for instance, should be dis- turbed as little as possible, and grows best on a flat piece of ground in full sun. Its white flowers make a beautiful contrast with the bright pink ones of Phlox Vivid. The Trailing Phloxes, of which Phlox G. F. Wilson with very pale lavender flowers is one of the best, are very easy to propagate, as long-rooted trailers can be detached in the autumn and all quickly grow into strong plants. The tufted kinds are a little more APRIL NOTES IN THE GARDEN 77 difficult. Cuttings often fail to strike, and the best plan is to put some leaf-mould round the plants in spring. The shoots will root in this, and they can be detached in early autumn, and, if protected from drought when planted, will stand the winter in the open ground. Phlox amoena is not so pretty in growth as the different varieties of Phlox subulata; but it flowers very early, and its pink blossoms are beautiful. It grows at a great pace, and can be propagated by simply breaking off pieces close to the ground and planting them in the open in early autumn. Phlox divaricata and P. ovata are fine species which flower later. The rock garden at this time of year is more in- teresting than the border, since Alpine plants are more rapid in their spring growth than the plants of the lowlands that have a longer season of activity; but borders are, or ought to be, rapidly putting on their beauty. Pansies and Forget-me-nots are com- ing out—the early Myosotis dissitiflora is in full bloom — the April Tulips are beginning to flower, and the Wallflowers are in bud. Wallflowers this year are poorer than usual, since many gardeners were unable to shift their seedlings in the drought of last summer. This shifting of seedlings as soon as they are about three inches high is one of the most important details in the culture of Wallflowers, and the neglect of it is the chief reason why they are often poorly grown even in pretentious gardens. Indeed, there are some gardeners who can grow Orchids better 78 STUDIES IN GARDENING than Wallflowers, for the Wallflower, though a hum- ble plant, requires a certain treatment a little out of the ordinary routine. The seed should be sown very thinly in the open border and in poor soil, about the beginning of May. The seedlings should never be allowed to get crowded. When they are about three inches high they should be shifted, so that they may not make long tap roots and be difficult to move later on. They should have their crowns pinched out a little later, so that they may break into compact bushy plants, and in early October they should be moved into their quarters for the next spring, and planted very firmly in the ground. If by this time they have made long tap roots and grown leggy and straggling, they will resent moving, and very likely die off in the winter. Daffodils in the grass are now within a few weeks of their prime. Some of the earlier kinds, such as the Tenby daffodil and pallidus praecox are going over; and Princeps is now in full bloom. Pallidus praecox, the most beautiful of the earlier kinds, is rather capri- cious. It usually dies out soon in a border, but will often last for years in the grass on a northerly half- shaded slope. Even the Tenby Daffodil thrives better in the grass, though it is supposed to be a vigorous variety anywhere. Princeps is one of the easiest of Daffodils. Its flowers look rather commonplace when picked or in the border, but they have a peculiar beauty in the grass. There is no Daffodil, however, to equal the Queen of Spain as a grass flower. Bulbs APRIL NOTES IN THE GARDEN 79 planted last autumn are now in full blossom. Since they are all imported from Portugal, they flower some weeks earlier than bulbs that have been some years in English ground. The Queen of Spain often dies out quickly in a border, particularly if the soil is rich. In the grass, in a northerly half-shaded slope full of the roots of trees, it flourishes as well as in its native home, and it surpasses nearly all the most costly new varieties in beauty. There is still a good deal of uncertainty about the question what bulbs will thrive in the grass and what will not. Tulipa silvestris, for instance, is supposed to be an excellent grass plant; but the present writer finds that it ceases to flower and dwindles away in the grass after a year or two. Tulips in this respect are peculiarly uncertain. It is probable that those which require great summer heat to ripen them off are kept too cool by a covering of grass; but this scarcely applies to T. silvestris, which is a native species. It is to be desired that some one should make large experiments with Tulips in the grass and should publish the results; but few gardeners would care to sacrifice a great number of bulbs for the public good. Grape Hyacinths of all kinds seem to thrive even in coarse grass, so do Ornithogalum umbellatum, O. nutans, and O. pyramidale. Scilla sibirica is apt to dwindle in coarse grass, and so are the Chionodoxas and Pushkinia libanotica. The more vigorous Alliums will thrive in grass not too coarse and in full sun. A. neapolitanum will soon be in flower. Fritillaria Meleagris, of course, is at home 80 STUDIES IN GARDENING in the grass. There appears to be a common idea that it will grow only in the Thames valley and other particular localities; but it is quite an easy plant in most places, where the soil is not too hot and poor. The Crown Imperial (F. imperialis) will grow in the grass only where the soil is rich and rather heavy. It dwindles after a year or two in a light soil and re- fuses to flower. It would be an interesting experi- ment to sow a patch of ground with some short moun- tain grass and plant several tufts of Gentiana acaulis in it. They might thrive; and then, again, they might not. This plant is one of the most capricious in exis- tence. Last year it flowered profusely even in poor soils. This year it is more flowerless than usual. It will prosper like a weed in some places, and in others, with apparently the same conditions, it will do nothing. The old idea was that it ought to be left alone; but this treatment is of no avail where the crowns grow smaller and smaller. The best plan in such a case is to dig it up in wet weather, in spring, and to plant each separate crown with plenty of space to itself. It ought to be coming into flower now, and with some lucky gardeners perhaps it is. With the present writer it is not. PINKS INKS are common enough in our gardens, yet they are not grown so much or so well as they might be, and the florists are so taken up with carna- tions that they have rather neglected the possibilities of the pink. No doubt carnations are worthy of all the pains that have been spent upon them; no pinks can compare with them in variety of colour, and few in duration of flowering period. But carnations ex- act much care and skill if they are to be grown really well, and need to be constantly renewed; whereas many pinks ask for nothing but a sunny place and a well-drained soil to thrive for years without attention. Carnations, too, often need to be carefully staked; and this is a grave defect in a plant of so low a stature, and one from which most pinks, especially the natural species, are entirely free. The chief beauty of the best pinks is their habit of growth. They are beauti- ful in winter as well as in summer, and they bear their flowers as if they were a joy and not a burden to them. Most of them will endure any amount of drought and can be propagated most easily by seed, cuttings, or division. All that they need to make them perfect garden plants is a longer flowering period, a greater va- riety of colour, and in some cases rather larger flowers. Now, different species or varieties have all these vir- 81 82 STUDIES IN GARDENING tues. What is needed is to combine them all in one plant; and, since most species hybridize very readily, there seems to be no reason why this should not be done. Already there are some new pinks appearing with large, single, and bright-coloured flowers; and there are others with double flowers that blossom al- most as long as carnations. What we want is a new race of single flowering pinks, of compact habit, vigorous constitution, large brilliant flowers, and a long period of bloom. Vigour of constitution is a most important point, and one too often overlooked in the development of the carnation. Unfortunately, the pink which flowers longest and has the largest and most brilliant flowers, Dianthus sinensis, and its fine variety, D. Heddewigii, is not a true perennial; and varieties which have a strain of its blood in them are apt to be delicate. It has been conjectured that there is a strain of D. sinensis in the carnation, which may be the reason for its comparative delicacy, and also in some of the mule pinks, which are beautiful plants but need to be constantly renewed by cuttings. In time, however, the better qualities of D. Heddewigii might be combined with the virtues of the most vigor- ous natural species. There are already, of course, many beautiful garden pinks; but most of them have double flowers and bloom for only a short season. The florists of the past took great pains to produce pinks very precisely laced or edged. They were dominated by the rules and standards of flower-shows; but, now that the PINKS 83 pink has ceased to be a fashionable show flower, there is some chance of its more rational development. The material out of which it can be developed is very varied. There is a great number of wild species of pinks, many of them most valuable garden plants, and most of them quite easy to grow. It is of these that we propose to speak in some detail, since they are less known to the ordinary gardener than they ought to be, and since the florist makes less use of them than he should. Unfortunately there is a great deal of confusion about their names, due, no doubt, to the extreme readiness with which they hybridize. It is difficult to distinguish species from varieties, and the same pink has often different names in different nurserymen’s catalogues. Dianthus plumarius is the best known of all the natural species and the parent of most garden pinks. It is very variable and hybridizes readily with other species. If a number of plants are raised from seed, very probably not two will be exactly alike in their flowers or in their habit. The type has fringed flowers of a pink colour slightly tinged with mauve. The best plan is to raise it from seed and to keep only the best plants. Seedlings are sometimes neat and com- pact in growth, sometimes straggling. Their flowers vary in size, colour, and shape. The amateur who will persevere in raising seed year after year from his best specimens may in time come to have some very fine plants. D. plumarius will thrive anywhere in full sun and well-drained soil, and is particularly use- 84 STUDIES IN GARDENING ful for covering dry, sunny banks. It can be raised from seed, sown either when ripe or in spring, with the greatest ease, and will usually seed itself pro- fusely. For this reason, and because of its rapid growth, it is not a plant for the small rockery, but it can be grown just as easily in the border as the ordi- nary garden pinks. Dianthus cesius (the Cheddar pink) is also variable and hybridizes very readily with D. plumarius and other pinks. The type is very tufted and low grow- ing. The leaves are glaucous green, the flowers of a bright pink, and irregularly indented. It is a lime- stone plant and thrives best among rocks in a rubbly soil or in a wall. It is apt to die in the winter on the level, but lives long and often grows to a considerable size in chinks of a rough stone wall. It is an excellent rock garden plant, as it does not spread too quickly. All it needs is a high and dry place in full sun. It can be raised very easily from seed; but seedlings usually vary a good deal, and, if the seed is bought, they often bear little resemblance to the type. In- deed, the species hybridizes so readily that it is not likely to come true from seed unless the seed is saved from plants isolated from other pinks. Some of the hybrids, however, are very beautiful, having the close tufted habit of the species and larger and even brighter flowers. With this plant, too, it should be easy to get some fine varieties by saving seed year after year from the best specimens. Dianthus deltoides, the Maiden Pink, is a pretty PINKS 85 plant and a native of England. It has leaves that are not glaucous like those of most pinks, but bright green, and pink flowers with darker spots. There is a very pretty white variety, one with brighter flowers, and one with glaucous leaves. D. deltoides is very easily grown in any light soil, and seeds itself pro- fusely. The white variety comes fairly true from seed. It should be grown in great masses in a large space to itself, where it can seed freely. In a small rock garden the seedlings encroach too much. The plant commonly called Dianthus fragrans is really a variety of D. plumarius with white, very sweet- scented, flowers. The double variety has a scent of overpowering sweetness, and is a very beautiful plant. The true D. fragrans is very rare. Dianthus mons- pessulanus is a closely tufted pink with dark glaucous foliage. It has large fringed pink flowers, very fragrant. It is easily grown among rocks in light soil with some leaf mould in it, and prefers limestone. Dianthus arenarius and D. petraeus are plants about the names of which there seems to be some uncertainty, at least among nurserymen. The plants usually sold under these names have very narrow grassy leaves, a very tufted habit, and white fringed flowers. According to M. Correvon the species both have pink flowers, but the plants usually sold may be merely white varieties. In any case they are charm- ing, and will grow in the driest and hottest places. In fact, they are suitable for the very top of the rockery, where they will spread into carpets as thick and even 86 STUDIES IN GARDENING as turf. The poorer the soil the better they flower. In a rich soil they are apt to run all to leaf and to damp off in the winter. D. noeanus is a new and very pretty plant, growing in close tufts which do not spread to any great size. It has elaborately fringed white flowers, and is, per- haps, the only pink with a disagreeable scent. It should be raised from seed and grown among rocks in poor soil. Dianthus alpestris is a pretty little pink, easily grown among rocks, with bright pink fringed flow- ers, not more than 6 in. high. The true Dianthus suavis appears to be a variety of D. plumarius, but a beautiful pink with very delicate white flowers is sometimes sold under this name, and also under the name of D. gallicus. The writer does not know its true name, but it appears to be a species, as both in growth and in flower it is very distinct from all other pinks. The true Dianthus gallicus has pink spotted flowers, and is usually not perennial in our climate. Dianthus sylvestris is a fine pink, which, in spite of its name, likes full sun. It does not spread much like other pinks, but grows in a single close tuft of thin dark green leaves. The flowers are bright pink, and the stems are rather weak and apt to lie about on the ground. This is the only defect of the plant, which is easily grown in dry, hot gardens. Dianthus superbus has flowers unlike those of any other pink. They are pale flesh colour, with greenish-yellow spots, and most elaborately fringed and curled. The leaves PINKS 87 are rather broader than those of most pinks. D. superbus is not a true perennial, but is worth grow- ing, as it can be raised very easily from seed, and will thrive on the north side of a rockery in a dry place. Unlike most pinks, it seems to like a certain amount of shade and grows in woody places in its native land. There are several pinks with their flowers in clusters like those of the Sweet William, and some of them are well worth growing. Dianthus atrorubens and D. cruentus, both with small flowers of a very deep crimson, are among the best. They will thrive in any sunny place, and are rather border than rock garden plants. D. carthusianorum has paler flowers, and is not so pretty, though pretty enough. D. giganteus, the tallest of pinks, will grow more than a yard high, but the flowers are small in proportion to the height. It is scarcely worth growing except as a curiosity. D. Knappii is a pretty clustered pink with pale yellow flowers. It should be grown on the rockery, where its culture is easy. All of these are easily raised from seed, which can be obtained without difficulty. D. cinnabarinus, however, which has clustered flowers of a curious cinnabar red colour, is one of the rarest of all pinks, and at times goes out of cultivation al- together. It comes from Greece and is not very perennial in England. This fact, since it often fails to ripen seed, accounts partly for its rarity. Other- wise it is easily grown, and worth growing for its curious beauty. 88 STUDIES IN GARDENING None of the pinks which we have mentioned are at all difficult to grow. There are, however, one or two high Alpine species which require some care, and one, D. glacialis, which is so difficult as to be scarcely worth attempting in England. The most beautiful of the higher Alpine species is, perhaps, D. neglectus. It can be distinguished from all other pinks by the pale yellow colour of the under- side of its petals, which are otherwise of an extraor- dinarily brilliant pink. The leaves are grassy and short and grow in close tufts; they also are not quite evergreen, like those of most pinks, but almost wither up in the winter. D. neglectus is not really difficult to grow. It should be planted tight in chinks between the rocks, in a soil consisting mainly of mortar rubble, with a little leaf-mould and sandy loam. It roots deeply, and when established does not suffer from drought, if rocks are all round the roots. It can be easily raised from seed, and this is the best way to grow it, as the plants become enervated if they are kept too long in frames. The seed should be sown when ripe or in spring in pans of light, gritty soil, and the seedlings planted out into their permanent homes as soon as possible. D. neglectus likes the fullest sun, and is the most brilliant coloured of all wild pinks, and one of the most brilliant coloured of all Alpines. It appears to hybridize pretty readily, and one sometimes sees seedling forms with all the beauty of the type, but more vigorous and larger in all respects. There seems to be no reason why a very PINKS 89 brilliant race of pinks should not be obtained by crossing it with other and stronger species. Dianthus alpinus is a very distinct pink, perfectly prostrate, with green leaves rather broad for their size and more like those of D. deltoides than of any other pink. The flowers, which rise only about 2 in. above the ground, are bright pink, spotted in the centre, and very large for the plant. D. alpinus is more difficult to grow than D. neglectus, as it is impatient of drought in summer and also of damp in winter. It cannot be grown in a very narrow chink of the rocks, as it throws out runners and requires room to increase in. This makes it the more difficult to protect from drought. It should be planted on flat pockets rather low down in the rockery, with a south- west or south-east aspect and surrounded with small rocks half sunk in the soil, with a larger rock on the north side of it for its roots to run under. The smaller rocks around it will give it a certain amount of shade. The soil should be deep and should consist of one- third mortar rubble, one-third leaf mould, and one- third fibrous loam, all well mixed up together. It must be watered in hot weather, and top-dressed with leaf mould when first starting into growth in the spring. With these conditions it is not difficult to grow, though it is not a very long-lived plant. It can, however, be very easily raised from seed, which usually ripens in England, and should be sown as soon as ripe or in early spring. It can also be increased by cuttings. When plants appear to be failing they 90 STUDIES IN GARDENING will often recover if moved; and this should be done in spring. There is a pretty white variety, and the type appears to hybridize readily, but no valuable hybrids have been obtained yet. Dianthus callizonus is, perhaps, only a local variety of D. alpinus, but it is a distinct and even more beau- tiful plant, with glaucous leaves and brilliant pink speckled flowers. It should be treated like D. alpinus and does not seem to be any more difficult. It is still very rare. Dianthus glacialis is too difficult, perhaps, to be worth growing in England. At any rate, it is scarcely ever seen in English gardens. It needs the same culture as D. alpinus, except that it will not endure lime, and must be even more carefully pro- tected from drought in the summer. The true plant is seldom to be obtained in England; and hybrids or other species are usually sold for it. D. Freynii is the smallest of all pinks, with little pink flowers. It should be grown like D. neglectus, and is not more difficult. There is a very beautiful minute mountain pink with large white fringed flowers, which is sometimes sold as D. squarrosus. The true D. squarrosus, however, is a much larger plant, of no particular beauty or interest. The present writer is ignorant of the true name of the white pink in ques- tion, and it is seldom seen in English gardens. It has very minute grassy leaves, and the flowers are borne about 24 in. abeve them. It requires the same cul- ture as D. neglectus, but is easier to grow. There are many more species of pinks, but many of them are PINKS ot much alike and probably only varieties. The whole genus requires to be thoroughly overhauled by a com- petent authority. THE IMPROVEMENT OF GARDEN FLOWERS HE first article upon this subject provoked some controversy, but it also elicited more ex- pressions of agreement than the writer had expected. It seems to be clear that the taste in flowers is chang- ing; that a great many gardeners are no longer con- tented merely with large blossoms; that we are learning to look at a plant as a whole, and not to think of it only as a flower-producing machine. A writer in one paper, disagreeing violently with the article in question, said that it was worse than use- less to set up principles of taste, since they were sure to be wrong or else to be misapplied. It did not ap- parently occur to him that all selection or improve- ment of flowers must be based upon some principle of taste or other. Otherwise it would be quite random and objectless. The issue is not between principles of taste and no principles, but between one principle and another. Now, the development of a great many garden flowers has been controlled by the principle that a plant is a flower-producing machine and that every part of it except the flower is mere surplusage. The ideal of this development would be reached in a plant that came up like a mushroom, leafless, and 92 IMPROVEMENT OF GARDEN FLOWERS 93 with a little stalk, and a huge flower at the top of it, and which continued to do this through all the flower- ing months of the year. This ideal has almost been reached in some double Begonias and in the dwarfest Snapdragons, and if you wish to have your garden all flowers these are the kinds of plants you should grow. Now, there certainly are a good many people who wish to have their gardens all flowers; and the idea that a garden plant should be grown only for its flowers is very deep-rooted. The present writer has heard of a rich man whose orders to his gardener were that his beds and borders should never contain any plants not in flower. A vast army of plants in pots was kept in the background, and these were bedded out just as they were coming into blossom and re- moved as soon as their blossom was over. Now, it is obvious that this kind of gardening is very expensive, and, further, that it prevents the growing of many beautiful plants which cannot be treated in this way, or which, if treated in this way, never show their true beauty. But that is not the point which we wish to make for the moment. Very expensive gardening may be beautiful, and there are plenty of fine plants which can be turned out of pots when about to bloom without spoiling their beauty. Our point is that a garden all flowers is not so beautiful as one in which there is plenty of greenery to contrast with the flowers. Most people agree with this up to a point, but they do not carry the principle far enough. Even the gardener who likes his beds to be all flowers 94 STUDIES IN GARDENING likes them to blaze against a foil of green turf. But he does not understand that the contrast of greenery is most beautiful when it is most closely interwoven with the flowers themselves, both by means of the intermixture of flowering plants with plants out of flower, and also by means of the leafage of a plant that is in flower. For it is only such a closely inter- woven contrast that displays the full beauty of in- dividual flowers and also of individual plants. In a bed of Geraniums or Begonias, grown for their blaze of colour, it is the colour alone that we see and think of. The individual plants, the individual flowers, are nothing. The beauty of the arrangement may be considerable — it is absurd to pretend that all bed- ding out is ugly — but it is a beauty only of masses of strong colour, without form and, above all, without character. Now no beauty interests us for long un- less it has character. We cannot in pictures produce a beauty that satisfies by means of mere abstractions. The purely decorative picture, the picture that con- sists merely of an arrangement of forms and colours, as nearly abstract as the painter can make them and put together to make an agreeable pattern — a pic- ture of this kind pleases at the first glance very likely; but our interest in it is quickly exhausted, because there is no character in its component parts. So there is no character in the individual plants of a flower-bed that is intended merely to produce a blaze of colour; and in the same way our interest in such a bed is exhausted after the first glance. A great IMPROVEMENT OF GARDEN FLOWERS 95 picture is full of splendid harmonies and contrasts; but the objects harmonized and contrasted are not mere abstractions. They are people and things which the painter has seen, and they are woven together into a pattern, without losing their own individuality, by the controlling emotion of the artist who uses them, not merely as pieces in a decorative game, but as a means of expressing that emotion. Now, gardening is, no doubt, a trivial art compared with painting, but still it is an art, or may be made one; and the same principles apply to it. The true art of gardening is based upon a profound interest and de- light in plants, just as the art of the great painter is based upon a profound interest and delight in the things which he represents. The true gardener is concerned with the character of his plants as the great painter is concerned with the character of what he paints; and it is by growing his plants so that they display their character as freely and completely as possible that the gardener makes the most beau- tiful and interesting kind of garden. Now it is obvious that this cannot be done by a gardener who regards a plant as a mere flower-pro- ducing machine; for the flowers are only part of the character of a plant, and they may be so developed as to obscure the plant’s natural character altogether. Flowers may be, and in most gardens plants are, the most important element of beauty; but their beauty is not independent of the plant, and cannot be con- sidered apart from it until they are picked. The gar- 96 STUDIES IN GARDENING dener who grows his plants only for their flowers thinks always of the flowers as if they were picked, and of his beds and borders as huge nosegays; and the kind of gardening which removes a plant as soon as it goes out of bloom is more like the arranging of flowers for the dinner table than like true gardening. It is a purely decorative art without the deep and satisfying beauty of character. This kind of beauty is what delights us so much in nature and what often seems to be utterly beyond the gardener’s attainment. Wild plants, we should remember, do not grow for their flowers alone. They have to fight for their lives, and every part of the plant bears a part in the struggle. We are not suggesting that plants in a garden ought to fight for their lives. It is the gardener’s first duty to eliminate the struggle for existence; but he must never forget that the character of plants has been produced by that struggle, and that their beauty is always dependent upon their character. He can often improve upon that beauty, because he has eliminated the struggle for existence. He can often, to begin with, grow his plants much better than nature grows them. He can in many cases enlarge their flowers with ad- vantage, and brighten their colour. But while he does this he should always think of every plant as a whole, of its natural character, and of the right pro- portion between its leaves and its flowers. At once, of course, there arises the question how are we to decide upon the right proportion between leaves and flowers; and here comes in the question IMPROVEMENT OF GARDEN FLOWERS 97 of principles of taste. If we are to grow plants for their flowers alone, the flowers should be as large as we can make them and the leaves as small. If the leaves are not to be seen for the flowers so much the better. But if we are to consider the natural char- acter of each individual plant, then we should take care that the flowers are not so large as to obscure that nat- ural character, and in particular to interfere with the plant’s natural habit of growth. I a wild plant bears its flowers on strong upright stalks, we should not make these flowers so heavy that the stalks cannot support them without being staked. If a wild plant bears large flowers and has a compact habit of growth, we should not dwarf it till it looks like a hunchback. If the flowers naturally have great beauty of form, we should not double them so as to destroy that beauty on the chance of obtaining another beauty of colour. To object to all double flowers would be pedantic. There are many plants that depend for their flowering beauty upon a mass of blossom, and it may often be increased and prolonged by doubling as in the case of the double Arabis, the double Genista tinctoria, and the double Silene maritima. In other cases the beauty of the flower is in colour rather than in form; and the colour may often be intensified by doubling as with the Dahlia, the Carnation, many Roses, and most Chrysanthemums. There are certain forms of flowers that are obviously unsuited to doubling; others that can often be improved by it. Thus bell-shaped flowers, such as those of most Campanulas, or trumpet- 98 STUDIES IN GARDENING shaped flowers, such as those of most Lilies, are pretty sure to be spoilt by doubling — and, indeed, doubling, in the case of these, seems to be against nature. There is no reason in the nature of things why the bell of Campanula persicifolia should be stuffed up with inner layers of petals. On the other hand, the outer ring of florets of most composite flowers is often in- creased when they grow wild in favourable conditions, and such an increase does no violence to the whole structure of the plant. So a good many composite flowers have been doubled without spoiling their beauty. But, even in the case of composite flowers, the doubling has been carried too far. Thus double Daisies have a pleasant, precise, old-fashioned kind of beauty; we have all loved them in our childhood and, therefore, we continue to love them still. But in a batch of seedling Daisies, all intended to be double, there will often occur single forms more beautiful than any double ones. These are usually plucked up and thrown away, since the gardener regards the single Daisy as a weed and the double alone as a garden flower. But there is no reason whatever why the single Daisy should not be developed into one of the most beautiful of all spring flowers, with large white or pink or crimson florets and with a shining golden centre. Even then it would not probably be more beautiful than the wild Daisy, but it would be more conspicuous. Thus in the case of doubling there are principles that could be applied pretty easily in most cases. IMPROVEMENT OF GARDEN FLOWERS 99 In some, of course, it would be difficult to say whether a plant would be the better or the worse for being doubled. Wherever there is a doubt it would be wise not to double it. There are so many other ways in which plants can be developed with a certainty of improvement. They can usually be made more vigor- ous; their colour can often be made brighter and purer. In some cases their habit is the better for being more compact. Thus some of the hybrid Larkspurs are finer plants in all respects than any of the species. The new garden varieties of Phlox decussata are in- finitely superior in colour to any of the older ones; some of the hybrid Pentstemons have a beauty and variety of colour and a vigour of growth far beyond any to be found in the species from which they have been produced; and the Tufted Pansies or Violas as they are commonly called, have both combined and improved out of all knowledge all the good qualities of Viola tricolor and Viola cornuta, which were their far distant wild ancestors. But in all these cases there has been no attempt to pervert or to conceal the natural character of the plants. The flowers may have been enlarged, but not so that their stalks cannot support them. The habit may have been made more compact, but it has not, except, perhaps, in a few Phloxes, been dwarfed into deformity. The eye may be trained in its appreciation of flowers, as of most other beautiful things; but it must be trained on a principle; and the only sure principle is that every plant be always considered as a whole, and 100 STUDIES IN GARDENING that its natural character be always borne in mind. It is a significant fact that the monstrous flowers have usually been produced in those plants which are treated in gardens in the least natural way — that is to say, in bedding plants, especially Begonias. On the other hand, in the case of plants which are usually grown naturally development has in most cases meant improvement. The florists have produced more new varieties of the Daffodil of late years than of any other flower. But their changes have been nearly all im- provements, and the Daffodil is a plant that nearly every one grows in a natural way, except when it is forced or in the case of very expensive new varieties. Thus the improvers of Daffodils usually have the whole plant in their minds, whereas the improvers of Begonias think only of their flowers. There can be no doubt that the practice of rock gardening has im- proved the general taste in flowers, for tricks cannot be played upon Alpine plants; they have to be grown as far as possible in their natural conditions, and their beauty is peculiarly the beauty of character, a beauty produced by the strange conditions in which they maintain their struggle for life. The gardener who once learns to love this beauty gets a keener apprecia- tion of the character of all other plants. He likes to see them growing as if they were self-sown seedlings, and he is impatient of any florist’s development or of any system of culture which deprives them of char- acter. Character, in plants as in men, is produced by struggle and by adaptation. In the garden both IMPROVEMENT OF GARDEN FLOWERS 101 the struggle and the need for adaptation are much lessened, the result of which is that astonishing changes can be worked upon many plants since they are re- lieved from the continuous even pressure of necessity. But if these plants are transformed so that they lose the character stamped upon them by their adaptation to natural circumstances, then they lose also the most significant part of their beauty, and look like manu- factured rather than living things. There are some people, of course, who like a flower to look manufac- tured, and in its artificiality see a proof of their own power over nature. This desire to make a thing look different from what it is, just for the sake of showing the maker’s skill, is the cause of much bad art of all kinds. It is the cause of nearly all bad art in the garden. CHEAP GARDENING HEAPNESS is a relative term in everything, and particularly in gardening, since a Daffodil bulb may cost anything from a farthing to fifty guineas. There is no doubt that gardening can be a very ex- pensive amusement, now that it has become fashion- able and millionaires have their rock gardens as well as their motor-cars. Luckily, however, the expensive gardens are not always the best. Indeed, very often they are the worst. In gardening it is not the plant that counts so much as the gardener; and very often the plant that costs a guinea is no more beautiful than the plant that costs nothing. Gardening may be cheaper as well as more expensive than it has ever been, provided the gardener is ready to take a little trouble and to exercise a little self-denial. Mr. W. P. Wright has lately published a book (“Beautiful Gardens”) in which he makes it his ob- ject to show how a beautiful garden may be cheaply made and maintained, and in his preface he deplores the expensiveness of modern gardening. But, after all, it does not matter very much to the true gardener. He can console himself with the thought that all the costly novelties, if they are good for anything, will probably be cheap some day; and if it were not that there are people ready to give large sums for them, 102 CHEAP GARDENING 103 these novelties would never, perhaps, be produced. Mr. Wright complains, too, that the writers of most gardening books assume the costliness of gardening. He will not assume it; and yet he mentions a good many costly plants in his book, or at least plants that will seem costly to the man who really wishes to garden cheaply on a fairly large scale. Mr. Wright may urge that he only mentions such plants in case his readers may wish for a few luxuries. But the gardener who wants an abundance of flowers, and wants them cheap, will not be able to afford even a few luxuries. Those who have only a slip of garden with one small border and one bit of rockwork on it may afford, now and again, to pay half-a-crown for a Lily or Daffodil bulb. But those who have two or three acres of garden and wish to make them all flowery at a small cost cannot do this even once in a way. Their first problem will be to get cheap plants. Their next to economize in labour and manure. There are plants which need a great deal of manure in most soils, and others which need careful watering in hot weather, even though they may in some cases be cheap to buy. There are bulbs which need to be lifted and dried off, and others which, however well treated, soon die out in most. English gardens. There are shrubs, too, which must be protected in hard winters. There are carnations that must be constantly renewed by means of layers. There are bedding plants that need a greenhouse in the winter, and exact all the labour of shifting them into the greenhouse and out of it again. All of these 104 STUDIES IN GARDENING will have to be avoided, or very sparingly used, by the man who wishes to garden cheaply and who is not prepared to spend a great deal of his own time upon his garden. For him the labour problem will be more difficult, perhaps, than even the problem of stocking his garden; and yet both may be solved by means of a little knowledge and discretion. In the first place, the man who wishes to have a cheap garden must take the line of least resistance. He must find out what plants grow well in his garden naturally; and he must confine himself mainly to these. If he lives on a light, sandy soil, he must not grow plants that need much moisture and nourish- ment, for it will cost him money to supply them. If he lives on a stiff clay, he must avoid plants that will only flourish in clay if it is lightened and made porous with grit and leaf-mould. Directly he tries to fight with nature he will find that his bill for labour and for manure goes up. He must make it his object to humour nature; and, if he is a true gardener, he will find a peculiar pleasure and interest in doing that. The rich man or the man who has plenty of leisure may delight in overcoming nature; yet just as much skill may be exercised by the gardener who is busy and not rich in obeying her. But he must exer- cise some self-denial; and in particular he must cure himself of that itch for novelties which attacks all keen gardeners at some time in their career, and from which many never recover. Mr. Wright is inclined to think that the love of novelties is a vulgar passion; CHEAP GARDENING 105 that the rich man buys a costly new plant only to show that he can afford it. But good gardeners are not apt to be vulgarians, and nearly all of them love novelties and, if they can, pursue them in spite of a hundred disappointments. And yet this passion can be tamed by philosophy, as the present writer has discovered; and other and, perhaps, manlier passions can be nourished to take its place. Philosophy, based upon experience, admonishes the gardener that some novelties are not novelties at all and that others have nothing but their newness and costliness to recommend them. It also comforts him with the thought that, as we have said, most novelties, if they are worth having, will soon grow cheap. There are, it is true, some bulbs which have to be collected in their native homes every year, and which, being rare even then, never become very cheap. But there is always a chance that some year the collector will find a multitude of them, and that they will suddenly drop in price. Very likely they will soon rise again; but it is chances of this kind that make catalogues more exciting to read than any novel, and catalogues cost nothing. Anyhow the pursuit of novelties is sure to cause as much disappointment as delight; for the writers of catalogues have sanguine imagina- tions that take fire at a hint. They are ready to be- lieve all that the collectors tell them; and they do not spoil a tale in repeating it. Thus many novelties that flower so amazingly in the catalogues make but a poor show in the garden, and after one year’s trial 106 STUDIES IN GARDENING are described as “‘suitable only for botanical collec- tions’; which means that the ordinary gardener throws them on the rubbish heap if he cannot give them away to a friend. It is by considerations of this kind that the hunger for novelties may be tamed. But even the poor gar- dener is not cut off from them altogether, for he can often buy their seeds cheaply enough; and then, if they turn out to be rubbish, he can throw them away with the consolation that he has spent little upon them except the labour of raising them. Seeds, in- deed, are the mainstay of the poor gardener. If he will only raise his plants from seed, he can soon stock a large garden with beautiful flowers at the cost of a few shillings; and if he has a piece of spare ground which he can use for the trial of seedlings, in a few years by judicious selection he will be able to raise for himself specimens of many plants as fine as the finest florists’ varieties, and even finer, for he will be able to consult his own taste in the development of them. It is strange, indeed, how few people raise perennial plants from seed; and the only explanation can be that it never occurs to them to do so. They are ready to spend time and trouble in raising annuals and biennials, because it is the custom; but they are in the habit of buying perennial plants, and they con- tinue to do so, although many of them can be raised from seed just as easily as any biennial, and will flower just as soon after the seeds are sown. One could make a long list of perennial plants that every one ought CHEAP GARDENING 107 to grow from seed. But a few of them will suffice for examples. Larkspurs, Columbines, Hollyhocks, Pan- sies, Campanula persicifolia, C. carpatica, C. lacti- flora, nearly all the perennial Flaxes, Catananche, Lychnis Haageana, Oenothera macrocarpa, Anchusa italica, Coreopsis lanceolata, Geranium grandiflorum and other Cranesbills, Gypsophila paniculata, Pent- stemons and Scabiosa Caucasica. Many of these, if sown as soon as the seed is ripe, will flower the next year like biennials. All or nearly all will flower the next year, if sown in spring; and all can be raised from seed without any difficulty. But even those gardeners who do raise perennials from seed often take more trouble than they need, and with worse results than a simpler method would produce. It is common, for instance, for Hollyhocks to be raised from seed in frames and to be moved at least twice before they find their permanent quarters. The finest plants of Hollyhocks are those which have never been dis- turbed since the seed was sown in the ground. The best and easiest way of growing them, therefore, is to sow two or three seeds where the plant is wanted to grow, and when they are well up to pull up all but one of them. It is not easy to treat Snapdragons thus, because their seed is much smaller than that of Holly- hocks. But there is no need to raise them in boxes or frames. The best plan is to sow them out of doors towards the end of April. They will come up in hun- dreds, and can be shifted to their permanent quarters any time after a good downpour of rain. Pentstemons, 108 STUDIES IN GARDENING again, may be sown in boxes out of doors in May. They can be pricked out as soon as they are large enough into a reserve bed, and planted into their permanent quarters the next spring. Young plants that have not flowered will not usually suffer even from hard winters in fairly light soils, and, in any case, it is not difficult to give them a little protection. Of course, it takes more time to raise plants in this way than to start them in heat in early spring. Pent- stemons, for instance, will flower the same year if raised in heat, and so will Hollyhocks and Snapdragons. But the open-air method produces healthier plants, and costs nothing except the price of the seeds. All the perennials mentioned above can be raised from seed sown in the open border; but the safest plan with most of them, especially where the soil is heavy, is to sow the seed in boxes and to place the boxes in a cold frame until the seedlings are strong enough to resist all caprices of the weather. If this is done it is best to sow the seed in April, so that the plants may be a good size before the hot weather comes. They should be moved into the open air, however, as soon as possible, and then put into their permanent quar- ters in the autumn, where they will flower the next year. When one considers that a single plant of Oenothera macrocarpa costs sixpence, whereas fifty plants may be raised from a penny packet of seed so as to flower the year after sowing, the advantages of raising plants from seed are obvious. There are some plants, of course, that do not come CHEAP GARDENING 109 true from seed, so that if the gardener wants a par- ticular variety he must buy a plant and propagate from it by other means to increase his stock. But this is usually the case only with plants that have been developed by the florists, such as Larkspurs, Carnations, and garden Pinks, and Violas or Tufted Pansies; and this variableness adds a new interest to the raising of plants from seed, if the gardener has some spare ground which he can use for trial beds for his seedlings. If he does this and selects his seed judiciously year by year, he will probably obtain some very fine varieties of any plants to which he may give particular attention. The trouble of an annual sowing of Larkspurs or Columbines or Violas will be very small, especially if the seed is sown in the open ground when ripe, and the expense will be nil. The gardener who saves his own seed will probably have so much of it that he will be able to afford the risk of a sowing in the open border if his soil is not too heavy; and if he sows there, he will be able to leave the plants alone until they flower. There are some plants that can be so easily in- creased by other means that it is scarcely worth while to sow seed of them when once a few have been ob- tained; and there are also plants, as, for instance, most bulbs, which, if raised from seed, take years before they flower. But all means of propagation, even in the case of plants most easily increased, are strangely neglected by many gardeners. Nothing is easier, for instance, than to get a large stock from a 110 STUDIES IN GARDENING few plants of Tufted Pansies by simply taking off little rooted pieces and planting them in a cool place in light soil, keeping them well watered until they are established. If this is done as early as possible, and when the ground is thoroughly wet with rain, the offsets will soon make good roots and be strong plants ready to plant out in the autumn. This method may be employed with most plants that increase by means of rooted tufts or offsets, and it is often better than division, since it leaves the parent plant undisturbed. The main point for a gardener who cannot give much time to watering is to choose his opportunity when the ground is thoroughly soaked, and to plant his offsets where they are not liable to be shrivelled up by too hot a sun. The time for taking such offsets must vary, of course, with the habit of growth and the flowering season of different plants. Thus, if Tufted Pansies are cut back after their first flush of bloom they will throw up a number of fresh shoots which can be readily detached. Michaelmas Daisies, on the other hand, since they flower in autumn, and since most of them throw out rooted tufts of the greatest vigour in all directions, can be simply pulled to pieces and re- planted in spring. If this is done every tuft will be a strong flowering plant by the autumn. In every case the gardener should observe the habits of the plant he wishes to increase, and should treat it ac- cording to these habits. Bulbs, as we have said, usually take a long time to flower from seed, often about six years, but many CHEAP GARDENING 111 of them increase rapidly by means of offsets; and this means of increase also is often neglected, so that the bulbs become crowded and deteriorate. Bulbs that are to be increased in this way should be dug up when they die down, and the offsets separated from them. The main bulbs and the offsets may then be either dried off until the autumn or replanted at once. Some bulbs — as, for instance, many kinds of Tulips — are the better for being dried off every year; others, such as English and Spanish Irises and many Nar- cissi, like to be dried off occasionally. English gar- deners, even those who do not care to spend much on their gardens, are apt to be very wasteful with bulbs, especially with Tulips used for spring bedding. There is a common idea that they will not last in Eng- lish gardens. But if they are lifted when they die down and then dried off, they will not only last well, especially in light soils, but will often increase rapidly. The gardener who does not wish to spend much money on his bulbs can yet have a fine show of them, at least if his soil is fairly light, provided he is prepared to take a little care of them and to buy very cheap kinds; and luckily there is an abundance of cheap bulbs often as beautiful as the dearest. You can give ten shillings for a single Tulip bulb, but no Tulips are more beau- tiful than Picotee, which costs six shillings a hundred, or than Cottage Maid, which costs about four. You can give fifty guineas sometimes for a single Daffodil bulb; but Barri conspicuus, or Princeps, or John Bain, or the Tenby Daffodil cost about five shillings 112 STUDIES IN GARDENING a hundred, and they ought to be good enough for most people; while you can get a thousand of the old Pheas- ant-eye for fifteen shillings. You can get a thousand Spanish Irises or Crocuses for even less, and Squills of many kinds, Chionodoxas, Fritillaries, Allium, Dogtooth Violets, Galtonia, many kinds of Gladioli, Snowflakes, and of course Snowdrops, Muscari, and many less-known bulbs can be bought very cheap. There remain Lilies, and most of them are not cheap or easy to grow. The poor gardener must do without many kinds of Lilies; but he can grow the Madonna Lily, the Orange Lily (L. croceum), L. Pyrenaicum, yellow and red, L. Davuricum, L. elegans, the Marta- gon, the Tiger Lily, and, if he has a moist place in his garden, L. pardalinum, L. superbum, and L. Canadense. He can also get L. auratum, L. speciosum, and L. longiflorum quite cheap at sales; but he will probably have to renew them often, and this means labour as well as money. We have said nothing about Roses or shrubs in general. Many can be bought very cheap; but if they are to prosper, the ground must be deeply dug and manured beforehand. This costs money, of course; but a little preliminary outlay in deep digging and manuring, though many people are apt to grudge it, will always save money in the end. Have your bor- ders thoroughly well prepared before you put a plant in them, and you will have to spend less afterwards on plants and on labour. COMMON SENSE IN GARDENING ARDENING to the beginner seems to be all an arbitrary mystery. Some plants want this, he is told, and some that; and he can see no more reason for the diversity of their wants than for the diversity of their colours. He regards the expert gardener as a kind of magician, as one who can make all plants thrive by the very way in which he handles them, and who knows by instinct what they want. Now, it is quite true that the best gardeners do seem to have a way of their own with plants, and that they will often succeed with a plant they know nothing about where an inferior gardener, less ignorant, would fail. But they are not born with this gift. They are only born with the qualities and interests that en- able them to acquire it. The best gardeners are those who love plants and who, therefore, are for ever look- ing at them; who never pass a cottage garden with- out peering into it, who are always learning some- thing without effort or design in woods and meadows, on moors and mountain sides. In this they are like the born painter or like the poet in “How it Strikes a Contemporary,” who watched men for the love of watching them. Without this kind of love there can be no profound knowledge of anything. Taking notes with an object is a useful practice, but it is not the 113 114 STUDIES IN GARDENING best kind of observation, any more than cramming for an examination is the best kind of learning. One forgets the notes as soon as one has used them; but the knowledge got by loving observation stays in the mind and makes pictures there. It is because chil- dren observe disinterestedly that they have such long memories; and so disinterested observation is the secret of the gardener’s, no less than of the poet’s or painter’s, magic. But there is reason and method in the magic of all arts; and the great gardener’s love of plants only makes him a great gardener because he turns it into science. The passion of observation is what con- nects all excellent works of science and art. It makes the great artist something of a man of science, and the great man of science something of an artist; and gardening, in its humble way, is both an art and a science, and can only be practised well by the man who will learn it as an art and a science. He must not only be always observing, but also always experi- menting; and it is experiment alone that can make his observation profitable just as it is only observation that can teach him how to experiment. And the more he does of both the more he will be able to use his common sense in gardening and to see the reason and the system of things. The great defect of most professional gardeners is that, however well they have been taught a right routine, they do not know the reason of it, and therefore cannot apply it to things outside their experience. They have learnt COMMON SENSE IN GARDENING 115 what they know as arbitrary and isolated facts, just as children learn a number of dates from bad teachers of history; and these facts do not help them to learn anything new. The best gardeners are those who cannot endure that any fact they learn should re- main arbitrary and isolated. Every plant is to them a living and a reasonable being, and they wish to understand it as the poet wishes to understand men. They like to know the conditions of its native home and to see how those conditions have made its char- acter. They like to see how far it is adaptable to the ordinary routine of the English garden, and whether cultivation will improve it or injure it. Now, plants seem to differ in their adaptability in the most arbitrary way. Speaking generally, one may say that plants which have adapted themselves to very abnormal conditions have usually exhausted most of their power of adaptation in the process. Plants which have learnt to grow among snow and ice cannot endure the prosperity of a rich border. What is meat to a Rose or a Peony is poison to them. But this is not always so. Some plants that have learnt to thrive in adversity will also thrive in a pros- perity not too gross; and in the same way there are plants which, preferring prosperity, will also put up with a good deal of adversity, while there are others that will not endure adversity at all. The reasons for these differences in adaptability are usually unknown. One can only lay down a general rule, that the more normal the natural conditions of a plant the greater 116 STUDIES IN GARDENING is its adaptability; and this is a rule of much value in practice, although it is broken by many exceptions that can be learnt only by experience. Every good gardener likes to know the natural conditions in which all his plants grow. But he learns from experience that he will not always succeed by imitating those natural conditions as closely as pos- sible, for very often he will not be able to imitate the most essential of all, and for lack of that, it may be that all his other imitations will be merely mischie- vous. There is, for instance, a little creeping plant called Nierembergia rivularis, whose native home is in marshy places in South America. Most books on gardening, therefore, say that it should be treated as a bog plant; some that it should be planted in shady places. Now it is a plant that comes from a much hotter climate than ours, where, no doubt, it likes all the moisture it can get. But in England it likes all the sun it can get, and has not the same need of moisture. In England, according to the present writer’s experience, it will thrive in fairly rich soil, in a dry level place, provided it is watered in the hottest weather; but will not endure the cold of a damp place in winter. This is an instance of a plant with a considerable power of adaptation, which, since we cannot give it all its native conditions, would rather have none of them complete, but prefers that an average should be struck among them; and there are many plants like it. We have always to remember that gardening is COMMON SENSE IN GARDENING 117 not a natural process. There are very few plants that in most gardens can be supplied with exactly the conditions of their natural homes; and the aim of horticulture is to compensate for the lack of these conditions by artificial means. The skilful gardener, when he has observed the natural conditions of a plant, will always translate them, so to speak, into garden terms, when he proceeds to make use of his observations. He knows that most plants, fortunately, have a considerable power of adaptation to artificial conditions; but he knows, also, what are usually the limits of that power, and what artificial conditions are necessary to compensate for the lack of natural ones. Take, for instance, the case of manure, which is mainly an artificial aid to the growth of plants, and which, therefore, is used as a substitute for natural con- ditions and often as an improvement on them. Farm- yard or stable manure has more than one use. It is both a plant-food and a means of protection against drought. Now, there are many plants that like man- ure as a food; but there are also many, particularly among bulbs, that do not need it as a food but like it as a protection against drought. For such plants manure will be unnecessary where they are in no danger of suffering from drought. In a garden that lies low or has a heavy soil few bulbs need manure; in a gar- den that is high and dry many are the better for it. But manure, where it is used only as a protection against drought, must be applied much more cau- tiously than where it is used as a plant food, partic- 118 STUDIES IN GARDENING ularly in the case of bulbs. Most bulbous plants are apt to rot if manure touches the bulb itself, and to many of them manure is poisonous as a food. It should not, therefore, be mixed with the soil about the bulb, as it may be mixed with the soil abbut the roots of many gross feeding plants, such as Pansies or Ponies, but should be placed well below the bulb, so that the roots will either never reach it or will only reach it when they have grown strong and when the manure has lost its rankness. There are many plants, usually supposed to dislike manure, which are the better for it applied thus in light, hot soils. It is a common belief, for instance, that all Lilies dislike manure, and so the most of them do anywhere near the bulb. But in light soils the Madonna Lily, Lilium testaceum, L. Chalcedonicum, L. Szovitzianum, L. auratum, L. speciosum, L. pardalinum, and L. super- bum are all the better for a good layer of well-rotted manure placed well below their bulbs, to say nothing of easy Lilies like L. tigrinum and L. croceum. The manure benefits them not so much as a plant food, though some of them are even the better for this. nourishment in moderation, but as an artificial pro- tection against drought, since it holds moisture, which is drawn upwards towards their roots and bulbs by the heat of the sun just when they need it most. Ma- nure can be used in this way as a protection against drought for many surface-rooting plants which may not need it as a food. But the gardener, if he does not know for certain whether or not it may be poison- COMMON SENSE IN GARDENING | 119 ous to a plant, should be very cautious in his use of it. It is quite likely that many Alpine plants would be the better for a dose of manure underneath them as a protection against drought, if any one could be sure that their roots would not reach it. But un- fortunately they are apt to root very deeply, partic- ularly in search of moisture, and some of them, if their roots got down to a layer of manure, would quickly die of indigestion; for in their native homes they get very little nourishment, and so have come to need very little. There are many surface-rooting plants, however, that like manure both as a food and as a protection from drought, and they can be fed with it from above as well as from below. Mulching is particularly good for surface-rooting plants, since the juices of the manure quickly reach their roots and since the manure itself on the surface protects them from drought. Most surface-rooting plants are the better for some kind of nourishment applied from above, especially if they are plants that resent being moved into fresh soil. Thus Eremuri, which throw out thick roots in all directions just under the surface of the soil, will often thrive wonderfully where they would otherwise seldom flower if they are top-dressed in autumn or early spring with rich loam or leaf-mould, or with old manure off a hot bed. And in the same way the hardy Cypripediums, particularly C. spectabile, the roots of which run like a network of whipcord over the surface of the soil, should be dressed with rich 120 STUDIES IN GARDENING loam and leaf-mould once a year. With them this is a natural treatment, for in their native homes they get a covering of fallen leaves every autumn, which no doubt, is the reason why their roots come above ground. Gardeners are too apt to think that plants which do not like manure do not need to be fed in any way; and shrubs like Rhododendrons and Aza- leas often fail to do well in gardens because their soil is never enriched. In their native homes they too get an autumn mulch of fallen leaves, and they should have it in captivity. A good dressing of leaf-mould once a year will feed them and protect them from drought. Gardeners, for the sake of neatness, will often sweep all shrubberies clear of leaves and never remember that they are thereby robbing them of their natural nourishment. If the fallen leaves are removed they should always be replaced in the form of leaf-mould later on. This is but common sense in gardening; and the whole business of feeding plants should be governed by common sense, that is to say, by an understanding of every plant’s requirements. One of the first things that a good gardener seeks to know about a new plant is the nature of its roots, and when he knows this he can at least conjecture something about its treat- ment. He knows, for instance, that a surface-root- ing plant is more likely to suffer from drought than one that roots deeply. He knows that a plant with a single crown and a thick fleshy root is more difficult to divide than one with a number of crowns and a COMMON SENSE IN GARDENING § 121 network of small fibrous roots. The character of a plant’s roots will also tell him something about when it should be planted, a matter in which many gar- deners are curiously unintelligent. As a general rule, deep-rooting plants are best moved or divided in the autumn, because then their roots have time to re- cover and strike down as soon as growth begins in the spring. Such plants cannot usually be moved without much damage to their roots, and before their roots have recovered they are apt to suffer much from drought. If they are moved in the spring and if a drought follows upon their moving, they will not re- cover before the summer heats, and then they will live but a miserable life until the next year. Yet one finds that many gardeners are just as ready to move Oriental Poppies in April as Pansies; and if the Pop- pies remain miserable, stunted, and half withered tufts all the summer, the gardener regards it as an “act of God,” not as the result of his own stupidity. Of course, if a deep-rooting plant is not very hardy it should be planted in the spring, and if it is but a a small plant that can be moved with little or no in- jury to its roots spring planting will not check its growth. On the other hand, surface-rooting plants can usually be moved in spring without checking their growth at all, and in heavy soils the spring is often the best time for planting them, so that they may be strong and well-established before they have to endure a winter. There are no arbitrary rules about the time for planting or dividing. Most plants can be 122 STUDIES IN GARDENING moved at any time of year if only they can be pro- tected against drought or cold until they have estab- lished themselves. But since it is difficult to do this in summer and in winter, the spring and autumn are the favourite seasons for planting and division. There is a common idea that plants cannot be moved when in flower; but this is not always so. It is far better to move Gentiana verna or even G. acaulis in full flower than in late autumn, because they flower in spring, when they can be fairly easily protected from drought, and if they are well watered during the summer they will be well established before the winter comes again. But summer flowering plants suffer much if subjected to the double strain of flowering and moving in hot weather, especially if they have long roots. There are some plants that are best moved as soon as possible after they have flowered, so that they make good growth before the next year’s flower- ing. This is the case with German and other Irises of the same class, which will usually flower well the year after moving if they are moved about a month after they have flowered and are well protected from drought until they have recovered. The reason of this is that they begin to make their growth for next year soon after they have flowered, and that this growth is interrupted by a move in autumn. Bulbs, of course, should be moved when they are at rest; but some of them are only at rest for a very short time. The Madonna Lily, for instance, begins to make new growth in a few weeks after it has died down. COMMON SENSE IN GARDENING 123 Therefore, if it is to be moved at all, it should be moved as soon as it has died down; otherwise it will receive a check from which it may never recover. There are some plants which need to be moved pretty often if they are not to deteriorate, and the reason for this can generally be found in their habit of growth and rooting. Plants which have deep roots can often be left for years undisturbed, and often suffer for a time even from the most careful shifting. On the other hand, plants will increase rapidly with a network of surface-rooting runners or suckers, such as Sidalcea or most Michaelmas Daisies, are apt to exhaust the soil in which they grow, and often need to be moved every two years at least. Again, plants such as Primroses and Polyanthuses, and many other Primulas, which start with a single crown and in a year or two break up into several crowns, are usually the better for frequent division, as the different crowns are really different plants, and crowd each other. A plant like Primula denticulata needs to be divided every year when it grows strongly, otherwise it will soon produce only poor flowers; and this division should be done as soon as possible when it has more than one crown, so that the plant may recover in time to form its flowers for the next year. We have chosen, almost at haphazard, a few instances of the applica- tion of common sense in gardening, with the object of showing that there are obvious reasons for all the diversities of treatment which seem so arbitrary to the beginner. If he tries to understand the reason of 124 STUDIES IN GARDENING everything that he does, and if he also has a natural love of plants, he will in time acquire that habit of treating plants rightly which is called the gardener’s instinct. LILIES ILIES are perhaps the most capricious of all garden plants. Some are familiar to our gardens and easy enough to grow; but even the most familiar of all, the Madonna Lily, fails unaccountably some- times. Others will thrive in one place, but not in another quite near it which seems to offer exactly the same conditions. Others, again, will do well enough for a year or two, but then are pretty sure to dwindle away or die off suddenly; while a few have hitherto baffled all the skill of experts. Writers upon lilies are apt to make them out to be less difficult than they are, and to suggest that we have a more certain knowledge of their requirements than we really have. The consequence is that enthusiasts are often tempted into experiments that can only end in disappointment. The object of this article is to state what lilies can be grown in certain conditions with a fair certainty of permanent success, what lilies will do well for a year or two in English gardens, and what lilies still baffle all efforts to establish them. It is not possible, in the present state of our knowledge, to write with any certainty about the cultivation of the more difficult lilies, and, therefore, we shall not pretend to any cer- tainty about them. There are some difficult plants that are difficult for obvious reasons. There are Irises 125 126 STUDIES IN GARDENING that need more sun than our summers usually provide. There are high mountain plants that suffer from our wet winters. We know what these want, even if we cannot supply it. But we do not know with any precision what it is that a good many lilies want, or what kills them off so quickly in our climate. Many experiments have been made with lilies, such as Lilium Krameri, L. Washingtonianum, and L. Philadelphicum, and these experiments, whether failures or successes, have not led to any certainty. It is likely that most of the hardy lilies which annually fail in our gardens are very impatient of disturbance and never recover from it when they are imported to England from dis- tant countries. We have heard it said that some of the North American lilies, like some of the hardy Cypripediums, never flourish in captivity even in gardens close to their native homes. They are not likely, therefore, to recover from the shock of dis- turbance when they have made a voyage across the Atlantic. Sometimes, very likely, these lilies are moved more carefully and at more favourable seasons than at others, and this would account for occasional successes. But the ordinary gardener cannot count upon such precautions. He must take what bulbs he can get of the rarer kinds of lilies, and he must ex- pect to fail with them. The only chance of success with lilies that are very impatient of removal would seem to be to grow them from seed in England; and this has been done in some cases with excellent re- sults, though not yet, perhaps, with any of the most LILIES 127 difficult lilies. Some of the finest plants of Lilium Szovitzianum at the Royal Horticultural Gardens at Wisley were raised from seed by the late Mr. G. F. Wilson, and were either not moved at all from the seed-bed or were moved with practically no distur- bance. Lilium Szovitzianum is not a difficult lily, as lilies go; but there are very few probably in Eng- land to equal those at Wisley. This experiment of raising lilies from seed would be too slow, and per- haps too difficult a business for most amateurs, but it might be tried on a large scale by lily specialists and might result in the acclimatization of some of the most difficult lilies. Unfortunately, many of the most difficult lilies are abundant in their native homes, and so are imported in large numbers and sold fairly cheap in England, with the probability, and in some cases almost the certainty, that they will disappoint those who buy them. Before we proceed to speak of particular lilies, it will be well to say something about the culture of lilies in general. It has been said that no two kinds of lilies should be grown exactly alike, and certainly lilies vary more than most genera of plants in their wants. But one or two general rules may be safely laid down about them, and the first of these is that they all like a soil full of the roots of trees or shrubs. The reason of this is not quite clear. It cannot be merely that they like sharp drainage, since drainage supplied by other means will not make up for the want of a rooty soil. Some lilies will do well enough without 128 STUDIES IN GARDENING a rooty soil; but those who fail with any particular kind should try it in a rooty place, and they will often meet with immediate and inexplicable success. Lilies also all like good drainage, even if they need plenty of moisture. Their bulbs, with their loose scales, are more apt to rot in stagnant moisture than bulbs which are better protected, and it is well, in the case of bulbs, such as those of L. Leichtlini or L. Krameri, which are very sensitive to damp, to plant them sideways, so that the wet will not settle into their crowns and the interstices between their scales. Lilies vary as to the depth at which they should be planted, because some of them throw out roots from the stalk, and, therefore, must be planted deep enough for these roots to form, whereas others throw out roots only from the base of the bulb. L. candidum, L. testaceum, L. giganteum, and most of the Martagon division of lilies, except L. Hansoni and L. Leichtlini, root only from the base of the bulb. L. auratum, L. speciosum, L. Browni, L. longiflorum, L. croceum, L. elegans, L. Henryi, L. Krameri, L. tigrmum, L. Hansoni, and L. Leichtlini all root from the stalk. The beginner should ascertain in each particular case whether the lilies he wishes to plant are stalk or only bulb rooting. There are no lilies that like a very hot place, although some, such as L. Chalcedonicum and L. pomponium, need a good deal of sun; nor yet will any flourish in very heavy shade. The greater number do well among low-growing shrubs which will protect them from late frosts and also from the extreme heat of the sum- LILIES 129 mer sun. A great many lilies suffer very much from late frosts, and lilies such as L. auratum, L. specio- sum, L. Leichtlini, L. giganteum, and in particular the early L. Hansoni, should be protected from them with heather or other branches placed lightly about their young shoots. Lilies differ so much in the soil they require that no general rules can be laid down on this point. None, however, like a very stiff clay un- less it is well drained and lightened with grit and leaf-mould. They differ also as to the time at which they should be planted; some are best planted in early spring, others in early autumn or late summer. The lilies that will usually do well in the ordinary herbaceous border and are of such easy culture that even the beginner may attempt them with confidence are the following: — L. candidum, the Madonna Lily. The chief enemy of this is the notorious lily disease, and it can be best prevented by a right system of culture. In heavy soils the Madonna Lily should be planted in a sunny, sheitered place; and the soil should be lightened with mortar-rubble. It has been said that this lily objects to chalk, but we have seen it growing magnif- icently in a very chalky soil, and in our experience it likes lime in all forms. It also likes a very rooty soil; and in light soils it may be planted in a north border sheltered by shrubs, but not shaded by them. In light soils also it likes a good layer of well rotted cow manure well under the bulbs. In all cases the top of the bulb should be only an inch or two under the 130 STUDIES IN GARDENING surface of the soil. The Madonna Lily starts into growth again a few weeks after it has died down, and it is always injured by disturbance when in growth. It should, therefore, be planted as early in autumn or late summer as possible, and should only be dis- turbed, if at all, as soon as it has died down. When it is doing well, it should be left alone; and gardeners should not be allowed to disturb the soil anywhere near it. The forking and hoeing of gardeners is a frequent cause of failure with all lilies. When the Madonna Lily suffers badly from the disease the safest plan is to dig all the bulbs up at once and burn them, taking care not to plant new bulbs in the same place. They sometimes recover if they are dug up as soon as they have died down, and if the bulbs are well dusted with sulphur and placed in full sun on a shelf in the greenhouse to bake for some weeks. It is well always to dust the bulbs in sulphur when they are planted. When the disease first appears, it may some- times be cured if the leaves of the plant are sprayed with Bordeaux mixture. This should be done at intervals of a week or so, several times. Lilium tes- taceum is said to be a natural hybrid between the Madonna Lily and L. Chalcedonicum. It is, after the Madonna Lily, perhaps the finest of all garden lilies, and it is easier to grow, although it also suffers some- times from the lily disease. It grows very tall and has beautiful flowers of an apricot yellow with bright scarlet anthers. It should be treated like the Ma- donna Lily, but does not suffer so much from distur- LILIES 131 bance and remains dormant for a longer period. In- deed in most gardens it is best moved into fresh soil every three years or so. It should be planted in early autumn. In some soils it increases rapidly. L. croceum, L. Davuricum, and L. elegans are all good easy lilies and can be grown in the same way; L. elegans, a dwarf lily with many varieties, needing rather more sun, perhaps, than the others. They are all plants for the ordinary border, liking a good dose of manure well under the bulbs in light and poor soils, and some protection from surrounding plants in very hot places. They are best planted in the autumn and should all be at least half a foot deep, as they make stem roots. L. tigrinum, of which there are several good varie- ties, is equally easy and needs much the same culture. It sometimes suffers if too much crowded or over- shadowed by other plants, and also if it is grown in too exposed places, or where the summer sun strikes full upon it. Splendens is, perhaps, the best variety. L. Hansoni is a fine lily of the Martagon division with stout yellow spotted flowers. It will grow in any good border soil, but the flower buds are often killed by late frosts and should be protected from them. It does very well among low-growing shrubs, provided they do not overshadow it. L. Batemanniae is a beautiful lily sometimes classed as a variety of L. elegans. It flowers later, how- ever, than the other forms of L. elegans, and the flowers are of a glowing but soft orange scarlet colour. 132 STUDIES IN GARDENING It is a little more delicate than L. elegans, and likes a warm sheltered place and light rich soil. L. Pyrenai- cum, a yellow lily of the Martagon division, and its scarlet variety are both easy lilies that should be planted in the ordinary border in early autumn and then left alone. They like manure under the bulbs in a light or poor soil, and will do well both in sun and in half shade. L. Martagon is a little more capricious perhaps, and prefers half shade. It should not be disturbed when well established. The variety Dal- maticum is a much finer plant, and not more difficult to grow. The beautiful white variety is certainly more capricious. It likes a slight slope with a northerly aspect, and a rooty, stony soil. It must also be shel- tered both from strong winds and from the extreme heat of the sun. It is, unfortunately, rare and rather expensive, although an old plant. It sometimes thrives wonderfully in old cottage gardens without any atten- tion whatever, and fails when it is given every lux- ury. We have now to speak of lilies which need more care and more or less peculiar conditions, and of these we will deal first with those which can usually be permanently established in English gardens without much difficulty. Lilium Chalcedonicum is a fine lily with bright scarlet flowers and a near relation of the Martagon or Turk’s-cap lilies. It comes from the south of Europe and Asia Minor, and therefore re- quires a good deal of sun to ripen the bulbs. It should be grown in a warm place very well drained, and sel- LILIES 133 dom thrives without a strong dose of lime in the soil. In stiff soils this should be given in the form of mortar- rubble about the bulbs. It is supposed to be a capri- cious lily, and often suffers from disease; but this usually happens when it does not get enough sun or when it is injured by late frosts or stagnant moisture about the roots. It suffers less than most lilies from drought. It likes a rich soil, even a stiff loam if well drained and mixed with mortar-rubble, but it should be sheltered from cold winds. Such shelter may be given by Lavender or Rosemary bushes placed so that they will not overshadow it too much or screen it from the south. It looks its best growing among these southern shrubs, and it likes a soil filled with their roots. It should never be disturbed when thriv- ing, and is best planted in early autumn. It flowers towards the end of July. Lilium pomponium, a smaller lily, but very like it, should be treated in the same way, but is easier to grow and less subject to disease. It also likes mortar- rubble, especially in heavy soils, but lime is not es- sential to it. The red variety of L. Pyrenaicum is sometimes sold for it, but is an inferior plant. Neither L. pomponium nor L. Chalcedonicum should be planted deep, as they do not make any stem roots. The soil should be stamped hard about the bulbs, and should never be forked or disturbed when they are grow- ing. Lilium Szovitzianum is a splendid lily, tall and robust. The flowers are pale yellow with dark spots. 134 STUDIES IN GARDENING Well-grown plants are 4 or 5 ft. high and bear a dozen or more flowers. It likes a good loamy soil mixed with leaf-mould, but is said to thrive in stiff clay if well drained. It suffers from drought if ex- posed to the full heat of the sun, and should be grown among low shrubs or herbaceous plants. It will sel- dom thrive on a bare patch of ground. It is best planted in early autumn and takes some years to reach its full beauty; so it should not be disturbed when once well established. It grows very well in the grass in half shade at Wisley, and can be raised from seed, though this is a slow process. It is often called also L. monadelphum, but this is really a distinct species with flowers of a darker yellow. Three North American lilies —L. Canadense, L. pardalinum, and L. superbum — grow well and in- crease in a moist soil rich in humus, if they are protected both from cold winds and from the full heat of the sun. They like peat well enough, but prefer it enriched with loam and humus. L. par- dalinum and L. superbum will grow also in fairly dry shady places if they are well watered in dry weather. They do well among shrubs, such as azaleas, rhododen- drons, kalmias, &c., but they must not be smothered by them. When the soil is not naturally moist it is well to plant them in a slight hollow where the water will be collected and drain down to their roots. Their chief enemy is drought, and they will not usually thrive in the ordinary border. They should not be disturbed when established, and if grown in a suit- -LILIES 135 able place will increase in beauty and also in num- bers year after year. L. Canadense grows about three feet high, and has usually orange yellow flowers. L. pardalinum and L. superbum will grow 6 ft. high or more, and their flowers are bright orange scarlet. L. Grayi is a beautiful lily with crimson drooping flowers which is said to be a variety of L. Canadense and also to be not much more difficult to grow. Lilium giganteum, the tallest of lilies, grows over 10 ft. high. Its flowers are relatively small and not partic- ularly beautiful in themselves, though the whole effect of a plant in flower is very fine. It should be planted in April in a deep soil half loam and half humus, with the top of the bulb uncovered by soil, and it must be protected from late frosts and from drought. When this lily flowers the flowering bulb dies and throws offsets, which should be taken up and replanted sep- arately, and which will then flower in a year or two. It is best to start with small bulbs and not to expect flowers for a year or two. L. giganteum is a lily for woodland glades or the wild garden rather than for the herbaceous border. Lilium Henryi was only introduced a few years ago, and is a most valuable lily, perhaps no more difficult than L. tigrinum. In the shape of its flowers and in its growth it is like L. speciosum, but the flowers are deep orange yellow, and it grows to a great height. It is not particular about soil, but does best perhaps in deep loam and leaf-mould in a half-shaded place among low shrubs. It will stand sun, however, much 136 STUDIES IN GARDENING better than L. speciosum. The bulbs have a remark- able habit of travelling underground. Lilium Brownii is a magnificent lily, close to L. longiflorum, but with white flowers stained on the outside with brown. It is also much more lasting than L. longiflorum in our climate, and will often live for years in a soil of light sandy loam and leaf- mould and in a sheltered half-shaded place. It will not do well in cold soils or climates, and cannot endure stagnant moisture. It may be grown with care in the border, but is always a little capricious. There are several varieties of it. We will pass now to lilies that are usually short- lived in our climate, though some of them can be easily grown for a year or two. Of these L. speciosum is the easiest, and in some places will thrive for a good many years. It likes a deep soil of leaf-mould, peat, and loam, and a sheltered situation among low- growing shrubs. It should be protected from late frosts, from the extreme heat of the sun, and from drought. There are a good many varieties of L. specio- sum, of which Kraetzeri, with pure white flowers, is one of the best. L. speciosum flowers late in the year, and should be planted, if possible, with a southerly aspect, as otherwise the flowers may be spoilt by early autumn frosts. L. auratum requires the same culture, but is apt to die out sooner than L. speciosum. Its variety platyphyllum is more robust, and will sometimes last for years in English gardens. The chief reason why L. auratum and L. speciosum die out is probably LILIES 137 that our summers are not warm enough for them; and, since they cannot be exposed to the full heat of the sun, it is difficult to give them enough warmth. They do best in warm, sheltered half-shady places, and should never be planted with a north aspect, except in very warm parts of the country. They re- quire a good drainage, and in dry soils it is a good plan to sink drain-pipes vertically into the ground among the bulbs to such a depth that water poured down them will come immediately to the roots at the base of the bulbs. As they make large stem roots, they should be planted deep. Lilium longiflorum, of which there are several varieties, seldom does well for more than a year or so in the open. The flowers also suffer much from heavy rains. It should be treated like L. auratum, but endures sun better. The variety Takesima is perhaps the best for outdoor culture. Lilium Krameri is a magnificent lily with flowers like those of L. longi- florum, only pink. It is very delicate and should be grown in a warm, half-shaded place in a soil consist- ing mainly of rubble, sand, and leaf-mould. The drainage should be as sharp as possible, and it is well to surround the bulbs entirely with rubble and sand. It will sometimes endure for several years if very carefully grown. L. rubellum, a very small pink lily, requires the same kind of treatment, but is perhaps more robust. It does best on a dry, rooty bank, half- shaded. Lilium concolor and L. coridion are also small lilies that often die out in our gardens. They do best 138 STUDIES IN GARDENING in loam and peat or leaf-mould in a sheltered and half-shaded place. LL. Leichtlini is a pretty yellow- spotted lily that should be grown like L. speciosum, but is very impatient of stagnant moisture. L. tenui- folium is a most beautiful little lily with scarlet flowers somewhat like those of L. pomponium, but more delicate. It is easy enough to grow for one year in a well-drained, half-shaded place, and in a soil of loam and leaf-mould. Unfortunately it almost al- ways dies out after it has flowered once. It is prob- ably short-lived by nature, but it can be raised quicker than most lilies from seed; and, since it is one of the most beautiful of all, this is worth attempting. A good many North American lilies, though oc- casionally cultivated in English gardens, are either very capricious or apparently impossible to grow. Thus L. Humboldtii and L. Parryi occasionally do well for a time at least, but they are plants only for experts. L. Humboldtii appears to thrive in loam sometimes in the milder and damper parts of the country, L. Parryi seems to do best in a rather dry, half-shady place. Other North American lilies, such as L. Washingtonianum, L. Philadelphicum, and L. maritimum, have not yet, we believe, been grown with permanent success anywhere in England, even by Mr. Wilson at Wisley. It is well to surround the bulbs of all the more delicate lilies with silver sand and to place a lump of peat under them so as to en- courage root action. THE THEORY OF GARDEN DESIGN I HE fact that a third edition of Mr. T. H. Maw- son’s “Art and Craft of Garden Making” has lately appeared is a sign that the old naturalistic ideas of garden design are losing their hold upon the public; for Mr. Mawson, both in precept and ex- ample, is altogether against naturalism in gardening. This does not mean that he is altogether against nature. His advice, put shortly, is— Never imitate nature with intent to deceive; but, where there is natural beauty already in a garden, make use of it. It is mere pedantry, he says, to condemn all com- binations of nature and art. “Even in prosaic manu- factures many successes depend upon nature’s as- sistance and supplies wisely applied by man, notably in dyeing and fermentation and many others. An illustration of frequent occurrence is to be found in the combination of terrace walls built on the natural rock which crops out of the ground; a combination which is most effective when skilfully done. As- sisting or touching up nature is more a question of the spirit in which it is done, rather than the prin- ciple which calls forth criticism.’ This is not ‘very well expressed, but the meaning is clear and the il- 139 140 STUDIES IN GARDENING lustration apt. Both naturalists and formalists are apt to be pedantic in the application of their prin- ciples. The naturalist forgets that in ninety-nine gardens out of a hundred nature cannot be plausibly imitated, even if such imitation were the right aim of gardening. The formalist forgets that the material of a garden is for the most part living material and that there is no necessary incongruity between it and the living things of nature. A great part of the beauty of good formal gardening comes from the contrast between the limited and unchanging forms of things that are made by man and the variety and unceasing changes of plant life. The most familiar example of such a contrast is to be found in ivy or any other creeper growing up a house or a church or a bridge. But the beauty is lost or much diminished when the contrast disappears with any overgrowth of the plant. If a building is beautiful in itself, it should not be smothered in creepers; and, even if it is not beautiful, it has an air of desolation and neglect when so smoth- ered. There is, of course, a modern fancy for desola- tion and neglect, which is, no doubt, a reaction against extreme artificiality of life and the result of a disgust for the ugliness of most modern things made by man. It is, in fact, a kind of Byronism of taste; and, as Byronism was the result of unhealthy living, so this is the result of unhealthy art. In great ages of art men have never wished to make their gardens look like wildernesses or their houses like overgrown ruins. They have been pleased with their own handiwork, THE THEORY OF GARDEN DESIGN 141 and confident of their power to improve nature in subduing her to their own purposes. In a garden man subdues nature to his own pur- poses, and to pretend that he is not doing so is mere affectation. But, at the same time, there is no reason why he should make an arrogant display of his con- quest, why he should not use all beautiful accidents of nature that will not conflict with the aims of his art. There are some formal gardeners who want all their plants to look like architectural ornaments, mere vegetable repetitions of stonework conventions; and it is an unfortunate piece of luck for them that nature has produced some trees and plants that look as if man and not she had made them, and others that can be easily cut into any shape that takes the designer’s fancy. The use of these, or the misuse of them, deprives formal gardening of one of its chief beauties, that contrast between the forms of architec- ture and the forms of natural growth of which we have already spoken. It is just as absurd to attempt to make plants look like architectural ornaments as to attempt to make a garden look like a piece of wild nature, and in each case the absurdity comes from the same desire to make things seem what they are not, the desire that produces so many modern kinds of ugliness. A garden is not a piece of wild nature, and a plant is not an architectural ornament. All make-believes of this kind do violence to the essential character of the material which they use; and, whether they run into excess of naturalism or excess of formal- a 142 STUDIES IN GARDENING ism, they are wrong, because they are unnatural. But this is not to say that trees or shrubs should never be clipped. Their treatment must depend upon the uses to which they are put; and this is the funda- mental principle of all good garden design. If a plant is used as an ornament in the garden, then it should be allowed to grow to its fullest natural beauty. But, if it is grown for use, then it should be treated in any way that will make it more useful. Thus, if May- trees are grown for ornament, they should be allowed to grow freely, and not be clipped into any artificial shape, since no artificial shape can be so beautiful as the natural form of the tree. But, if they are used as a hedge, they should be clipped to make them serve their purpose. There is no make-believe in a hedge. It is, what it professes to be, a vegetable wall or en- closure, and there is no reason whatever why living vegetables should not be used for such a purpose as much as dead vegetables or as minerals. Also, there is no reason, of course, why trees of all kinds should not be cut back to enhance the beauty of their natural growth and blossom, or to prevent them from grow- ing where they are not wanted. The only rule about clipping trees or shrubs is that it should always be done not as unnatural ornament, but for some good practical reason, and when the reason is obvious the clipped tree very seldom looks ugly, and often has a peculiar charm of its own, because it gives evidence of human care and pains intelligently applied. Thus a clipped yew pleases us in a narrow cottage garden, THE THEORY OF GARDEN DESIGN 143 because it is clipped to give space, and even topiary work in such places is often pleasant enough, since the clipping is necessary, and the elaborate forms which it takes are merely expressions of the cottager’s fancy and of his delight in his work. But there is no such reason for clipping a yew on a wide expanse of lawn, and topiary work there is not an expression of the gardener’s delight in his work, but a mere task to which he is set by the whim of his employer. There- fore, we think only of the labour that has been wasted on it, and take no pleasure in it. The principles thus applied to the treatment of trees and shrubs should be applied to all matters of garden design. In laying out a garden we should consider not what are the rules of formalism or naturalism, but what is our object in making a garden and each particular part of it, and also whether our object is the best possible. The object of many modern gardeners is purely horti- cultural, and often it is not even to grow beautiful flowers, but merely curious or difficult ones. When that is so, the garden cannot be beautiful, for, if the gardener does not aim at beauty, he may be sure that he will not attain it. But, assuming that the gardener wishes to grow beautiful flowers, we may further assume, if he has any intelligence, that he wishes to display their beauty to the best advantage, and he cannot do this without some grasp of the prin- ciples of garden design. If he thinks that he has only to imitate nature, let him remember that nature pro- duces her own beauty in conditions quite different 144 STUDIES IN GARDENING from those of any garden. One condition which the garden eliminates is the struggle for life, with all its reckless profusion. The gardener is not content that a plant, when it has flowered and seeded, should take its chance of being smothered by other plants that flower later; and all that conflict and smothering, which delight him at their most beautiful moments in woodland and meadow as evidences of the prodigal- ity of nature, would vex him in a garden, as mere signs of idleness and neglect. Also, the plants in a garden are not, like wild plants, all natives of one country and harmonious either by association or by some natural law. They come from many different countries and natural conditions, and, unless arranged with care, often look incongruous together. There- fore, even if the gardener’s one desire is to grow beau- tiful plants and to display their beauty to the best advantage, he must, at any rate, design his arrange- ment of them on some principle both horticultural and esthetic, and he will often find it difficult to draw a sharp line between the horticultural and the esthetic problem. Both the health and the beauty of a plant are spoilt if it is smothered; and a plant which grows naturally in some peculiar conditions will often neither thrive nor look well in ordinary conditions and among plants that grow naturally in such conditions. Directly the gardener begins to consider not merely the beauty of the plant in itself, but the question of its environment as affecting that beauty, he is drawn into the whole question of garden design, at least in THE THEORY OF GARDEN DESIGN 145 so far as it concerns the arrangement of plants, and then at once he finds that the naturalistic theory fails him. He cannot imitate nature in the arrangement of plants that have their native homes in different continents and may never have made each other’s acquaintance until they meet in his garden, and, if he attempts no arrangement at all, he will find that he has produced a chaos far uglier than the worst failures of nature, which are often ugly enough — the kind of chaos which is found in the ordinary mixed shrubbery of a suburban garden. It is plain, there- fore, that even the gardener who cares for nothing but his flowers, and thinks of his garden only as a place to grow flowers in, must yet consider design, if he is to display them to the best advantage. The original and true meaning of design is merely pur- pose. The gardener who designs his garden has an zsthetic purpose, and therefore goes further than nature, which, in the arrangement of plants, so far as we can tell, has no esthetic purpose at all. But directly he begins to consider the design, even if he consider it only from the point of view of his flowers, he will find that he can have no design without some degree of formality. He wishes, for instance, for some contrast between two plants of very different char- acter, so that the beauty of both may be enhanced. That contrast will probably be insignificant in only one example. He must either, therefore, repeat it at intervals along a border, or else emphasize it by the use of a good many plants of the two contrasting 146 STUDIES IN GARDENING kinds, arranged together in one place. In either case there will be some formality in his arrangement. Some of the most eloquent advocates of natural gar- dening have devised the most elaborate and often excellent schemes for the planting of borders, and, the better their schemes are, the more formality there is in them. They protest against the word formality, because it makes them think of carpet bedding and ribbon borders; but these are only coarse and art- less examples of formality. A fine formal design does not catch the eye and drag it along a long line of dis- cordant colours. It has its splendours and its quiet places, its multitudinous and solitary beauties, its contrasts and its harmonies both of form and of colour, like a picture by Titian. It may not look formal, but, if it is both restful and exciting to the eye, rais- ing expectations only to gratify them, we may be sure, and we shall discover by a little analysis, that it has a formal basis, like a great piece of music that at a first hearing may seem to be a wilderness of beauti- ful sound. The present writer has always found that any arrangement of plants which has struck him by its beauty has been based upon the repetition of cer- tain dominant features, and such a basis is formal, although it is also found in the best effects of nature. Nature supplies motives for design as she supplics material, but because they are accidental in her we are not to suppose that they will come by accident in the garden. So far we have spoken only of design in the arrangement of flowers, on the assumption THE THEORY OF GARDEN DESIGN 147 that the garden is to be considered only as a place for plants. In another article we will speak of design on the assumption that the garden is also a place for human beings, an assumption which must, of course, have a considerable influence on the treatment of flowers in it. II It is only in modern times that the garden has come to be thought of as a home for flowers and not for human beings. Mr. Mawson in his “Art and Craft of Garden Making” says that the medieval and Renaissance gardeners regarded the garden as a “becoming setting to the mansion.” The landscape gardeners, beginning with Capability Brown, ignored the home altogether in their designs, and also its inhabitants. Civilized human beings were anachro- nisms in their gardens, though Adam and Eve, in fine summer weather, might have harmonized with them. They were realists, Mr. Mawson says, and the older designers were idealists. But in this case, as in many others, common sense was with the idealists, since their idealism was based upon plain facts. Gardens, they knew, were meant to be inhabited, so far as our climate would allow, by civilized human beings; and they tried to make them as convenient as possible for that purpose. The landscape gardeners, forget- ting this fact, made their gardens as unhomely as they could. They also had far less interest in horti- culture than the earlier designers. They were in- 148 STUDIES IN GARDENING clined to leave that, like everything else, to nature. But, in spite of them, the deep-rooted English delight in flowers persisted and increased all through the nineteenth century; and since it was no longer con- trolled by the old principles of garden design, the cultivation of flowers became the chief purpose of pleasure gardening, until at the present day most people would stare if it were suggested to them that pleasure gardening ought to have any other purpose. And yet it is plain enough that a pleasure garden is meant to give pleasure to human beings and should be designed with that object. Let it be as beautiful as it can be made, since beauty is one of the main elements of pleasure, but let its beauty, like that of a living room, be controlled by use. Have as many flowers as you like, but think of them, not as the reason for the garden’s existence, but as its ornaments, as you would think of the ornaments of a living room. A museum may be interesting, but it is not a place to live in; nor yet is a garden that is a mere museum of plants. If garden designers would forget the quarrel about formal and realistic gardens and design only for pleasure and comfort they would avoid many of the errors into which they commonly fall. If pleasure and comfort were their main objects they would al- ways make the best of existing conditions. They would not try to turn a suburban slip of ground into a wilderness or a wild hillside into a tea garden. Their problem would be simplified, because it would become concrete instead of abstract, just as the painter’s THE THEORY OF GARDEN DESIGN 149 problem is simplified when he has to decorate a given space instead of painting pictures at large. sthetic problems are always most successfully solved when they are not purely esthetic; and it is be- cause the problem of garden designs has become purely esthetic that it now seems so difficult. If the designer, instead of asking himself where he should place his herbaceous border and where his rock-garden or his rosary or his plantations of flowering shrubs, were to consider how best he could contrive places of coolness and shade for the summer and sheltered sunny walks for the winter, he would find that his ssthetic and horticultural problems were beginning to solve them- selves. Flowers he would use as decoration and, using them so, he would soon discover a principle for their arrangement. Trees and shrubs he would employ mainly for use, to give shelter and shade; and therefore he would avoid the random planting of them now so common. He would also avoid ex- cesses of formalism, since he would not clip those trees or shrubs that were planted for shade, but only those which needed clipping that they might grow close for shelter. He would be very sparing in his use of what are called ‘ornamental conifers,’ now so often misused by formalists and naturalists alike. He would not plant a row of Thujas in front of a yew hedge because he wished to advertise the fact that he was a formalist; nor would he dot them anyhow about a lawn for no reason whatever. Monkey Puzzles he would leave for gardens where there are monkeys to 150 STUDIES IN GARDENING puzzle. It is in the treatment of trees and shrubs that naturalistic gardening has failed most com- pletely, since it has forgotten their uses and treated them as mere instruments of illusion. As Mr. Maw- son says, they should be employed for use, and there should be no concealment of the fact that they are so employed. “The various flower gardens or tennis lawns . . would have their divisions, whether hedges or other arrangement, so treated as to express at once their use. To get shade, instead of creating it entirely by means of loose masses or clumps of trees, he (the designer) would obtain it by means of alleys, covered bowers, pergolas, or avenues, each of which would show at once the designer’s intention.” The ordinary mixed shrubbery certainly does not show at once the designer’s intention, since as a rule he has no in- tention whatever, except to find a place for shrubs; nor does it usually serve any useful purpose, since it provides neither shelter nor shade. Its purpose, in fact, is purely esthetic, and in ninety-nine cases out of a hundred it fails entirely in that purpose, as a mere hotch-potch of decorative objects must usually fail. Mr. Mawson insists that the main lines of a gar- den should usually be straight, or as straight as they can be made; and this is a safe rule to follow, pro- vided the designer does not make a fetish of it. They should be straight, not because we are growing tired of the fashion of curving lines, but so that they may express the designer’s purpose as simply and plainly as possible. A path, for instance, if it is a means of THE THEORY OF GARDEN DESIGN 151 providing a dry passage from one part of the garden to another, should be straight so that it may be short. But when a garden is designed to be a mere assemblage of decorative features, flower-beds and shrubberies and rosaries and rock gardens, then naturally the paths will wind about from one feature to another, expressing by their wanderings the designer’s lack of purpose. In the same way a hedge will be straight if it is meant to provide a sheltered, sunny aspect, and trees will be planted in an avenue or an alley if they are meant to provide shade. But if they have no such definite purpose they will be arranged ac- cording to the whim of the designer or the fashion. which happens to be in favour with him. Straight walks, straight hedges, and straight avenues may be ugly enough, and are always ugly when they are de- signed without any purpose or coherence; and it is certainly true that a want of purpose can be better concealed with curving lines, which is, perhaps, the true reason why they have become so popular. But the use of straight lines is a wholesome discipline to the designer, since, if he lacks purpose, they will never conceal the fact from him or from any one else, and his design will look silly, if it is silly; whereas, we are now all so used to naturalistic designs without use or purpose that we never even ask ourselves what their meaning may be. We are inured to misplaced shrub- beries, but we are not inured to misplaced hedges or avenues, and can still apply some principle of criti- cism to them. 152 STUDIES IN GARDENING To design with purpose, therefore, and to express your purpose clearly in your design, is in one way much more difficult than to make an arbitrary arrange- ment of flowers, grass, trees, and shrubs; but in an- other it is much easier. It is more difficult because the main lines of the design must be clearly thought out and fixed before a sod is turned, and because there must be a good reason for all of them. It is easier because, when once these main lines are determined, the details of decoration will be more or less clearly suggested by them, and so the problem of flower and shrub arrangement will be very much simplified. In a garden well planned for use and pleasure there will be room for flowers of all kinds arranged in many different ways. If, for instance, there is a nut walk for shade or any kind of alley made by deciduous trees, there may be Bluebells or Solomon’s Seal, or any other suitable flowers, planted naturally under the trees. There will be no incongruity in them merely because the trees are regularly arranged. When there is a straight path leading to a summer- house it will be natural to have a border on each side of it, since it is one of the pleasures of a garden to walk between flowers. According to the principles of naturalistic gardening, summer-houses were de- signed to be homes for earwigs rather than for human beings, and, considering their ugliness and incon- venience, it was only right that they should be hidden away, as they usually were, where no one could see them. But if a garden is to contain a summer-house THE THEORY OF GARDEN DESIGN 153 at all, that summer-house should surely be both use- ful and beautiful, and should be placed where its use and beauty will be greatest. There is something prosaic and superfluous about a summer-house close to a house. It should, if possible, be at the other end of the garden and where it will command a good view of the garden. Then the path connecting it with the house will be one of the main features of the design. Perhaps there may be a border on each side of this path for its whole distance, so that there shall be a vista of flowers all the way from the drawing-room window to the summer-house. The summer-house itself, also, should have its front, at least, thickset with flowers, just as there should be flowers close round the house. It is a common defect of purely horticultural and naturalistic gardens that flowers are seldom placed in them where they can be most easily enjoyed by the inhabitants of the house. Flowers should be concentrated, if possible, where they can be seen and smelt from the drawing-room windows, and in places arranged for the comfort of human beings. Sunk Dutch gardens are such places; and their formal- ity is the result, not of mere fashion, but of the desire to make a pleasant outdoor home both for flowers and for human beings who wish to enjoy them. Their clipped yew hedges give shelter to both, and the fact that they sink in regular stages ensures different con- ditions to suit different plants. It provides sharp drainage above and moisture below. In fact a sunk Dutch garden is only a kind of formalized sunk rockery; 154 STUDIES IN GARDENING and it is formalized because it considers human beings as well as plants. A great many rock plants may be grown in it so that their beauty will show to the great- est advantage. In fact, now that we have so many rock plants, unknown to our ancestors or neglected by them, Dutch gardens may be made more beau- tiful than ever before, with sheets of Lithospermum prostratum interspersed with Arenaria montana, with contrasts of Silene alpestris and Campanula muralis or of Veronica prostrata and the yellow Helianthemum. All these will harmonize with the blind bow-boy or the dancing fountain just as well as the customary duller plants; and their flowers will shine as much against smooth masonry as against rough-hewn rocks. A Dutch garden is intended for the display of flowers in detail, and no better place has ever been contrived for that purpose. There is one great advantage which the modern designer has over his predecessors, and that is in the use which he can make of steep banks and slopes. These, since they are obviously inconvenient resting- places for human beings, should be treated by the designer as spaces to be decorated. The older de- signers, apparently, despaired of decorating them with flowers, and therefore built them up, when they had the money, with walls —a very costly process. The naturalists usually covered them with turf or with the few varieties of shrubs, usually ugly and uninteresting, that would thrive on them. But now, luckily, we know of many beautiful flowers that will THE THEORY OF GARDEN DESIGN 155 thrive on them; and therefore it is only right and natural to cover them with such flowers, using rocks where they are needed, to protect the plants from drought and to prevent the soil from washing away. The rock garden is always a difficult problem in gar- den design, and many people who cannot do without the beauty of Alpine flowers make no attempt to solve it. They place their rock garden in any place horticulturally convenient without considering whether it has any congruity with the rest of their design. In some cases this cannot be helped. If your garden is all flat, and if you must have a rock garden, no art will make it agree with formal surroundings. But if there are any steep slopes in your garden, some wildness in the planting of them will appear natural even if everything else is formal; and, even if they seem suitable to the growth only of the easier rock plants, they can usually by a little contrivance be arranged so as to provide homes for the more delicate Alpines. Yet this obvious use of natural slopes is often neglected where there are rock gardens placed in the most unnatural and incongruous positions. Garden designers, in spite of the naturalistic move- ment, are still unwilling to take the line of least re- sistance, and would rather do violence to nature, even when professing to imitate her, than adapt her to their own purposes and coax her into the service of man. SOME DETAILS OF SUMMER GARDENING T the end of June the garden is in its prime, and the gardener is supposed to enjoy the fruit of his labours. Yet there is plenty for him to do if he cares to do it, and he can find for himself a hun- dred little tasks besides weeding and watering, the performance of which will make all the difference to the future beauty and even well-being of his plants. This is the time, for instance, for attending to spring flowers that have now gone out of bloom. The gar- dener should seize the opportunity of wet weather to di- vide all spring flowering plants which need dividing, for it is much better to do this now when the plants have the whole summer to recover in than in the autumn, when they have no time to make new growth. There are a great many Primulas, such as P. denticulata, P. rosea, P. Sikkimensis, P. Japonica, and even Prim- roses and Polyanthuses, which deteriorate quickly unless they are divided when their crowns begin to multiply; and it is only safe to divide the more deli- cate of these soon after they have flowered. Auric- ulas, too, and many kinds of Alpine Primulas are the better for occasional division and replanting, and this is the time to do it, provided they can be pro- tected from drought afterwards. This applies also to many spring-flowering plants which flower best 156 DETAILS OF SUMMER GARDENING 157 from a single crown, as, for instance, to the double Daisies, which need to be divided and replanted every year, especially in light soils, if they are not to de- teriorate quickly, and to the delicate little Morisia hypogzea, one of the best early-flowering plants for the rock garden, and one which many gardeners com- plain that they cannot keep long in health. The reason usually is that they are afraid to disturb it, since it is a deep-rooting plant. They therefore allow it to form a number of crowns, which it does very quickly, and which crowd each other in a narrow in- terstice between the rocks, with the result that it grows feebler every year. It should be taken up as soon as it has gone out of flower, and after all the crowns have been carefully divided they should be planted separately in cool places between the rocks and in fresh deep compost of loam and leaf mould. There are many spring flowering plants which need the same treatment especially in light or poor soil, and the gardener can usually discover which they are by observation. When he sees that a plant breaks up into a number of crowns after a year or two and begins to flower poorly, then he may be pretty sure that the only possible remedy for its deterioration is division. Division, of course, may kill the plant, but it is always worth trying when the only alter- native is deterioration. Aquilegia glandulosa and its beautiful hybrid A. Stuartii are plants which often die out or cease to flower after a year or two in the south of England, and the only remedy for this is 158 STUDIES IN GARDENING careful division as soon as they have gone out of flower. By this means they may often be perpetuated and a good stock of plants may be obtained; but division or any kind of disturbance in the autumn usually results in their death. It may seem strange that plants should need such artificial means to keep them in health in gardens, when they flourish in a state of nature without any help except from nature; but it must be remembered that they grow wild only in conditions naturally most favourable to them, and that many of them have very short lives and never reach that perfection which we demand of them in gardens. Nature’s chief object is that they should reproduce themselves, and, provided they do this, she is careless what becomes of them afterwards. But in the garden we do not always wish them to re- produce themselves. We may have enough of a par- ticular plant, or we may have a particular variety which will not come true from seed, and we may there- fore wish it to spend its energy in making new growth rather than in ripening seed. The ripening of seed is the most exhausting process that a plant undergoes, and there are many plants that kill or permanently weaken themselves by profuse seed-bearing. Such plants may often be saved from death by the removal of their flowers as soon as they wither; and even true perennials are often much benefited by such removal. There are a great many evergreen plants that soon grow straggling and unkempt if they are never cut back, and the time to cut them back is when they DETAILS OF SUMMER GARDENING 159 have just gone out of flower, so that they may be freed from the strain of seed-bearing. If this is done, they will usually soon make a vigorous new growth and look fresh and green again by early autumn; some of them, too, will flower a second time. Among such plants are Aubrietia, Saponaria ocymoides, Veronica prostrata, the Helianthemums, many kinds of pinks, the smaller Achilleas, Alyssum saxatile, the Cerastiums, the Creeping Phloxes, and Iberis sem- pervirens and its varieties. Cutting back is not neces- sary for any of these plants, as they are all fairly vigor- ous perennials; but they are greatly improved in vigour and appearance by it, and some of them, such as the Helianthemums, will live much longer for it. Pansies and Violas, too, are the better for cutting back as soon as they grow leggy. If they do not suffer from drought after the operation they will soon make vigorous new growth, which will prolong the life of the pansies; and, in the case of the Violas, will provide an abundance of cuttings. But there are no plants that benefit more by cut- ting back than profuse flowering shrubs, and many of them often suffer much in our gardens from the want of it. This is particularly the case with shrubs which are not very hardy, such as the Cistuses. These will often survive a hard winter if they are cut back as soon as they have flowered and never allowed to grow straggly. The cutting back not only saves them from the exhaustion of bearing seed, but also seems to con- centrate their vigour. There are many shrubs, too, 160 STUDIES IN GARDENING like most of the brooms, that are not very long-lived by nature, but live much longer if they are cut back after flowering. Cutting back is particularly useful in a poor soil, when shrubs are always apt to get straggly, especially if it is accompanied by a mulching of manure or leaf-mould to encourage new growth. When a shrub seems to be doing badly, it will often take a new turn if it is cut back and mulched in early summer, and this is particularly the case with Rhodo- dendrons and Azaleas. If they are cut back at all hard they will probably not flower the next year, but they may be transformed into sturdy compact plants, and one year’s blossom is a small price to pay for that. Roses, too, especially in a light soil, may often be much benefited if they are cut back after their first flush of bloom, but the gardener must not hack at his Roses, or, indeed, at any shrubs or plants, blindly. He must always be quite clear in his mind before he does anything as to the reason why he pro- poses to do it. His object in trimming a shrub may be merely to prevent it from seeding, in which case he will only cut away all the heads of the flowers. Or it may be also to promote a vigorous new growth by the removal of shoots which have done the duty for the year by bearing flowers, in which case he will cut away not only the flower heads, but also the shoots which bear them, so far as they seem to be exhausted by the process. Or he may wish to thin a shrub that is getting crowded by the removal of the older and weaker wood. The first of these operations may be DETAILS OF SUMMER GARDENING 161 performed on all roses after their early summer bloom; the second on roses, such as the dwarf polyanthus, which throw up shoots bearing crowded heads of bloom; the third on the many roses that flower only once in the summer. These roses should not be pruned at all except when they are first planted, or if they seem not to be thriving; but all roses that are not pruned at all, or are pruned but little, need to have their older wood cut away at intervals. Those who grow roses as flowering shrubs and not as mere flower- producing machines will naturally prune them as little as possible, since a rose that is cut hard back every spring will never have time to grow into a shapely plant, unless it is a very vigorous variety in a very rich soil. Luckily, most roses will flower well enough for garden purposes without very severe pruning. But when roses are little pruned there is the more need to trim and to thin them, and judicious trim- ming and thinning, done not only in the spring or au- tumn, but also after their first flush of bloom, is one of the chief secrets of success with them and with many other flowering shrubs. There is no routine about such trimming and thinning. In each case the gardener must exercise his common sense and be guided by observation and experiment. It is always safe to cut out old wood that seems to have lost its vitality, or even younger shoots that seem exhausted by an excess of blossom. But some roses throw up new growth much quicker than others; and some throw up shoots bearing only masses of bloom which, 162 STUDIES IN GARDENING as soon as the bloom is over, seem to have fulfilled their use. Such shoots may be treated like the flower- ing shoots of herbaceous plants and cut down as soon as their flowers are all withered, to encourage the pro- duction of new flowering shoots. Other roses make new wood more slowly and their wood is more en- during, bearing several crops of blossom in the same year, or year after year. But in nearly all roses the ~ wood deteriorates in time and should be cut away to encourage new growth; and this operation is best done after the blossom is over. There is some difference of opinion about the cut- ting back of herbaceous plants and the extent to which it should be carried. No one, of course, would cut a shrub back hard except in the early spring or late autumn, since the spring is the time at which it makes its new growth, and if it is cut back hard in the sum- mer it may make no new growth and suffer for want of leaves to absorb food from the air. Whatever cutting back is done in the summer must leave enough growth to perform this function. This precaution must also be taken to some extent with herbaceous plants. But most of them throw up new growth much more quickly than most shrubs; some, indeed, such as Oriental Poppies, throw it up so quickly that they suffer very little if they are cut back very hard after flowering. Others, however, are slower in growing afresh and are weakened if they are cut down to the ground, especially if all their growth has been thrown into flowering stems, so that few or no leaves remain DETAILS OF SUMMER GARDENING 163 when these are removed. Such plants as, for instance, Larkspurs should only be cut down to within about a foot of the ground, so as to leave them with some leafage to absorb food from the air, just as bulbous plants ought not to be cut down until the bulbs are matured for the next year. Many herbaceous plants, if they are thus carefully cut down, will throw up new shoots and flower again in the autumn, since the cutting down relieves them of the strain of seed bear- ing. But this second bloom puts a yet greater strain on them, and they must be well fed if they are not to suffer from it. It is, therefore, a good plan to give a mulch of some rich material, such as manure or vegetable matter, to all plants of which a second crop of bloom is expected after the first crop of bloom is over. Such a mulch will also protect them from drought through July and August. Mulches, espe- cially of manure, are often applied at the wrong time. Thus in a light soil all the nourishment of a mulch applied in autumn often drains away before it can benefit the plants; while a mulch of manure applied in early spring, especially on heavy soils, often does more harm than good if the weather is cold and damp, since it holds the moisture and cripples the young spring growth of the plants, and also harbours slugs and snails. The best time for a mulch, therefore, is when the plants most need immediate nourishment and protection from drought — that is to say, in the height of summer and during or just after their blooming time. Such a mulch, especially on light 164 STUDIES IN GARDENING soils, is better than liquid manure, since it gives pro- tection from drought as well as nourishment; and, if it consists of spent manure from a hotbed, it will not be disagreeable either to the nose or to the eyes. THE RIGHT USE OF ANNUALS NNUALS are always apt to be a difficulty in the garden, especially for those who attempt to solve the real problems of gardening. Many of them, such as Nemophila, Shirley Poppies, and Love- in-a-Mist, are so beautiful that one cannot do with- out them; yet they flower but a short time, occupy a good deal of space, and leave an unsightly blank when they cease to flower. They are not like some perennial plants, such as the Pinks, which are beau- tiful even after their short flowering season is over. They have their little period of beauty, and then they give themselves up to business, the business of seed- ing. They seem to know that their lives must be short, and, therefore, to be utterly taken up with the task of the moment. When the time comes for them to think of posterity, they think of nothing else. They are like poor young mothers who grow haggard quickly in the nursery; and in the garden one has no room for haggard things. One does not wish to be reminded of autumn and the shadow of death in full summer, and therefore one is inclined to clear annuals away as soon as they go out of flower. But if a great bed of Poppies is rooted up in August, what is to take their place? Blank spaces at that time of year are a reproach to the gardener, a proof that he 165 166 STUDIES IN GARDENING has failed in the chief problem of his craft. They do not matter so much in a very large garden, where you can have a series of displays for different seasons of the year; but in a small one, where they cannot be ignored, they matter a great deal. In a small garden the problem of annuals may well seem insoluble, and, indeed, it is insoluble if they are grown in the ordinary way. ‘The great mistake which most people make with annuals is that they treat them too seriously, as seriously as Roses or Carnations, or any of the main and permanent ornaments of a garden. There has lately appeared an excellent book upon the culture of annuals; indeed, one of the best gardening books of our time.! The author of it, Mr. C. M. A. Peake, has obviously a great knowledge of his subject, which he imparts very clearly and concisely. There is no fault whatever to be found with his book except that he takes annuals too seriously. True, in his preface he says that the main use of annuals, at least of hardy annuals, is to fill a garden quickly with bloom, where for some reason or other the gardener cannot wait for the slower glories of perennials; and in such a case, no doubt, it is right to take annuals very seriously. But there are some annuals that one cannot do without even in permanent gardens, and yet few can give them either the space or the labour which would be necessary on Mr. Peake’s system of cultivation. He advises that a bed be prepared by deep digging 1“A Concise Handbook of Garden Annual and Biennial Plants.” By C. M. A. Peake. THE RIGHT USE OF ANNUALS 167 and manuring in autumn, that if the soil is sour it be dug out to a depth of 3 ft., and that a 6 in. layer of stones be put in for drainage, with better soil to fill up, and so on. Now, all his advice is very good, and, if it is followed, the result, no doubt, will be very fine flowers. But there are few gardeners who will be ready to take all these pains over annuals. If they prepare a bed thus elaborately, they will look for some permanent reward for their preparations. And yet Mr. Peake is right when he says that an- nuals need kind treatment, and that without it many of them are not worth growing. The problem, there- fore, is to give them kind treatment and yet not to waste all that treatment upon a display of a few weeks in the summer; and this problem is not insoluble. To solve it we should observe the manner in which annuals grow naturally. Nature does not sow them in spring and in masses all by themselves. Their seed falls as soon as it is ripe, in summer or autumn, and it is scattered about among other and perennial plants. Now we must not attempt to imitate the recklessness and uncalculating profusion of nature in our garden- ing; we must not, like her, sow seed in stony places or where thorns will spring up and choke it; our an- nuals should be sown, as all our plants should be planted, in borders properly prepared, so that we may have as little waste and failure as possible. But the gardener’s business is to imitate the successes of nature as well as to avoid her failures. There is no reason whatever why, with a little calculation and 168 STUDIES IN GARDENING contrivance, we should not grow our annuals among other plants as nature grows them, why they should not fill up blank spaces just when they are needed, and why they should not be overgrown as soon as their flowering time is over. It is true that by grow- ing them on this plan we cannot have the great masses of one single kind of flower which the present taste approves. But the present taste is a little too timid about mixtures and contrasts of colour. Few of those who advise upon the colour arrangement of flowers seem to be aware that nearly all colours go well to- gether in a garden, if only they are thoroughly mixed up. It is the half-hearted contrasts, where only two or three colours are employed, and those the wrong ones, that are really ugly. The Orientals know more about colour than we do, and in their colouring they imitate the audacity and profusion of nature. It is true, also, that if we mix up annuals with other plants, some of the annuals will probably be smothered. But this cannot be helped. Annuals are cheap, and the gardeners who take them most seriously thin them out most relentlessly. If we can leave it to nature to do the thinning, so much the better. Now nature will do the thinning for us thoroughly’ enough, sometimes too thoroughly, if we sow our annuals as she does, in the late summer or autumn. There is always a risk in doing this — a risk so great as to be scarcely worth running on very heavy soils. But on fairly light ones it is worth taking, since an- nuals are cheap. Gardeners are curiously timorous THE RIGHT USE OF ANNUALS 169 about sowing in the autumn, and it is commonly sup- posed that only a few kinds will survive the winter if this is done. Yet the present writer has found that even Phacelia campanularia, commonly supposed to be a rather delicate annual, will often live through the winter, if it is sown early enough, on a fairly light soil and in a light place. Indeed, it will flourish in a garden year after year from self-sown seedlings; and so will Love-in-a-Mist and Collomia coccinea, an excellent and little known annual, and Linaria Maroccana, to say nothing of Nemophila and Bar- tonia aurea, and Eschscholtzia and Cornflowers, and other annuals which are often left to seed themselves in our gardens. It is always risky, however, to trust to self-sown seedlings. They may not come up when you want them, and you do not know where they are until they germinate. Yet many people who observe that self-sown seedlings always do better than seed which they have sown will not make the obvious deduction from that fact. They think that there is some mys- tery in the process of natural sowing; whereas the fact is merely that nature sows at the right season, and that her seedlings, thinned out by her winter severities, have time to grow strong and root deeply before the summer heats. It is worth while, therefore, to experiment largely with autumn or late summer sowing, especially on light soils, since the experiments will be cheap in any case, and failures can be easily remedied in the spring. 170 STUDIES IN GARDENING There are some annuals, such as Nemophila, which become spring flowers of the greatest value if they are sown in autumn.! There are others, such as Corn- flowers, Sweet Sultan, Eschscholtzia, Poppies, and the annual Saponarias and Silenes, which very sel- dom do so well from a spring as from an autumn sow- ing. But the sowing must not be too late. The plants must have time to get some strength before the winter comes, and, therefore, most of them should be sown in September as early as possible. It is, of course, but little use to sow them when the weather is hot and dry, unless they can be thoroughly and frequently watered. Therefore, when there is a September drought, it is best to wait until it breaks up. Then sow annuals, not in great masses where they will leave a blank space when they die, but in any vacant patch in the border, and particularly in places occupied by dormant bulbs, such as Tulips, Daffodils, Spanish and English Irises. The lower growing annuals will do no harm to these, and, if the bulbs in their spring growth overshadow them a little, it will not matter much. Then, again, those annuals which are best sown in spring, such as Nasturtiums, can also be sown among bulbs, and the bulbs will often give them pro- tection from late frosts, while afterwards their flowers 1 Autumn sowing of annuals is not generally to be advised in the United States. In an interesting experiment, however, near Chicago in the spring of 1916, seeds of the following autumn-planted annuals were highly suc- cessful; Delphinium, Hunnemannia fumariefolia, Calendula, Calliopsis Drummondi, Antirrhinum, Brachycome iberidifolia, Candytuft, Erysimum Perofskianum. L. Y. K. THE RIGHT USE OF ANNUALS 171 will take the place of those of the bulbs. Or these spring-sown annuals may be placed among autumn Crocuses if the Crocuses are not too thickly planted, and then their season will be over and they can be cleared away just when the Crocuses begin to throw up their bloom. When annuals, such as Nemophila, Silene, and Saponaria, are sown so as to flower in spring, their places can be taken in turn by the more delicate half-hardy annuals or bedding plants that are put out at the beginning of June. It seems to the present writer that these half-hardy things are often unjustly decried, because they are nearly always mis- used. The common practice is to plant them in masses, so that large spaces of the garden have to undergo vio- lent changes and the ugliness that must result from such changes, often when the garden ought to be in its prime. The real use of half-hardy things, whether perennials or annuals, is to fill up blank spaces in the border, caused by the dying down of spring bulbs or by any mischance. There is no reason whatever why you should always plant fifty Cannas, or ivy-leaved Gera- niums, or Tobacco plants, where you plant one, or why one part of the garden should be filled only with hardy and another with half-hardy plants. There is no neces- sary incongruity between plants that are hardy and plants that are tender. It is merely convention that keeps them apart, as we may see from the Dahlia and the Gladiolus, which are half-hardy plants usually treated in a rational way and placed among hardy plants in the border. If we treat other half-hardy 172 STUDIES IN GARDENING plants thus, especially the best half-hardy annuals, we shall find them most useful, and we shall avoid the awkward intervals of ugliness inevitable with the ordinary bedding system. There are gardeners who have a nervous fear of growing anything near their Roses, even if they do not grow Roses for show. There- fore, they keep the soil about their Roses bare, with the consequence that their Rose beds look ugly for most of the year. But Rose beds can be covered with low-growing plants without injury to the Roses, if the soil is well fed; and annuals, especially half-hardy annuals, are particularly suited to this purpose, because the soil can be thoroughly enriched before they are planted out and after they are removed, and also be- cause their roots usually have not time to grow deep and thick and to impoverish the ground seriously. Half-hardy annuals can be combined with spring bulbs, such as Tulips, and in such a case bedding, both spring and summer, has a very good reason for its ex- istence. But annuals bedded out in this way must not be too tall or strong-growing, lest they keep light and air from the Roses. Excellent ones for the purpose, both because they are low-growing and because their colours can usually be arranged to harmonize with those of the Roses, are Ageratum, Dianthus Heddewigii, Nemesia in pink and white shades, Phlox Drummondii, and Verbena. No doubt the gardener who shows his Roses is right to grow nothing else near them; he re- gards the Rose, not as a beautiful flowering shrub, but as a flower producing machine. Those for whom the THE RIGHT USE OF ANNUALS 173 Rose is the chief of our flowering shrubs should grow it in beautiful surroundings, and they can do this only if they cover the ground about it with other beautiful plants. We have given a few suggestions for the use and treatment of annuals, and they are all based upon the idea that the annual should be employed as a stop- gap, not as a main feature of the garden. Since it is a transitory thing, it should not be treated as if it were permanent. It has its peculiar advantages, and it should be employed so as to make the most of these, and also so as to make the least of its peculiar disad- vantages. It is quick to come and also. quick to go. Therefore, use it for emergencies. It takes some skill and experience to do this cleverly, but the gardener who can learn how to do it will add a new pleasure to gardening and a new beauty to his garden. LATE SUMMER AND AUTUMN IN THE ROCK GARDEN OST mountain plants flower in spring and early summer. In the higher altitudes, of course, they begin late, as “the spring comes slowly up that way,” and last well into August. But our rock gar- dens are not in the higher altitudes, and Alpine plants in them usually flower earlier than in their native homes. A rock garden may have many flowers in March, and its greatest profusion of bloom will prob- ably come about the middle of June with the flower- ing of the Pinks. Then a decline will set in, gradual at first, but rapid in July; and in August many rock gardens contain but few flowers except the last of the Campanulas, especially if the summer is hot and dry. This is certainly a defect; and it is one which cannot be altogether overcome, though it may be lessened with a little contrivance. It is in the later months of the summer that one begins to appreciate the value of those plants and shrubs which do not lose their fresh colour and compact habit after flowering. There are many rock plants which spend all their energy and beauty for the year in blooming, and when their bloom is over look weedy and dishevelled. A rock garden filled with these is a dull sight by August, however splendid it may be in June. Such plants 174 THE ROCK GARDEN 175 are often the better both in health and in appear- ance for being cut back; but even then they have an ugly cropped look for some time; and one wants a rock garden to look always both neat and natural. There are luckily a good many plants, often not very conspicuous in their flowers, and some of them apt not to flower at all, which look both neat and fresh all the year round. One may, perhaps, grudge them the space which they occupy in the prime of the year and when all the plants are at their best; but afterwards they more than pay for their places. Every large rock garden should contain a good many of such plants, and particularly of the smaller and more prostrate shrubs, such as the prostrate Juniper, the Prostrate Rosemary, Cotoneaster congesta and Coto- neaster thymifolia, Santolina incana, and its dwarfer variety, Berberis dulcis nana, the dwarf Lavender, and the creeping Artemisias, especially A. sericea, which is the most vigorous and easily grown, and the more upright Artemisia argentea. There are also shrubs which have brilliant flowers in their season and yet never lose their beauty of foliage and habit, such as the Alpine rhododendrons, Helianthemum formosum (usually called Cistus); the varieties of the perennial Candytuft (Iberis sempervirens), espe- cially “Little Gem,” and the large flowered Iberis correefolia; and several species of broom such as the prostrate Genista pilosa, the double variety of Genista tinctoria, and the beautiful Cytisus purpureus.! Some 1 Not hardy in northeastern United States. L. Y. K. 176 STUDIES IN GARDENING of these are too large for a small rock garden, but others are not out of scale even in the smallest; and besides these shrubs there are many little plants that never deteriorate after flowering. Among these there is no need to do more than mention the Mossy Saxi- frages, the different varieties of Thymus serpyllum, especially albus and lanuginosus, the dwarf Alyssum saxatile, Lithospermum prostratum, which often flowers intermittently in the late summer and autumn, Veron- ica repens, Veronica pectinata, Arenaria tetraquetra, several species of Draba, Achillea rupestris and A. huteri, Tanacetum argenteum, and Saxifraga apiculata. All of these are beautiful in their habit of growth for long after they have ceased to flower, and most of them remain beautiful all through the winter, keep- ing the rock garden fresh and green when borders are all desolate. But still there remains the problem of flowers; for greenery is well enough, but we want something be- sides greenery in August and September, and in many rock gardens we do not get it. Yet there are a good many rock plants that bloom well up into the autumn, and a few which, if not rock plants, are yet well suited by their habit to grow among them and which are autumn blooming by nature. Most of the Pinks flower in June, though some of them continue to throw up blossoms intermittently until the frosts; but Dianthus noeanus, a little-known species from Asia Minor, flowers in August. It has a very neat tufted habit, and pretty white and curiously fringed THE ROCK GARDEN 177 flowers, and may be easily raised from seed and grown in any dry sunny place among rocks. Another late flowering plant of the pink tribe is Silene schafta, which also blossoms in August and September. It is not one of the most beautiful of the silenes, but easy to raise from seed and to grow; and its pink flowers are very useful, if a little dull in colour. Sedum Ewersii and §S. Sieboldii are both late flowering plants with pink flowers and neat grey leaves. They thrive in any dry place, but sometimes suffer from severe frosts. Their foliage dies down in the winter. Polygonum vaccinifolium is a most valuable late-flowering plant for the rock garden. It has a creeping habit and soon covers a good deal of space. It is deciduous, and its leaves appear rather late; but they remain fresh and bright until the autumn, and it bears its delicate pink flowers up to the frosts. It does well on the north side of the rock garden in rather poor soil if it gets plenty of light and air. In rich soil and shady places it often refuses to bloom. The beautiful Polemonium confertum mellitum flowers both in spring and in au- tumn; in fact, it is apt to flower itself to death. But it is easily raised from seed, and does well with a north- west or west aspect in sandy loam and leaf mould. Erodium reichardi, the smallest of the Erodiums, flowers into late summer, and so does Erodium ma- cradenium. In a large rock garden Nierembergia rivularis is a most valuable plant for the later months. It makes a bright-green carpet, which keeps its fresh- ness well up to the frosts, and continues to throw up 178 STUDIES IN GARDENING its large white flowers to the end of September, if it is grown on the flat in full sun, and top-dressed with leaf mould in the spring. It spreads so fast where it prospers that it is a dangerous plant for small rockeries. (Enothera marginata and O. taraxacifolia again are only plants for large rock gardens. O. marginata continues in bloom till September, and, where it thrives, increases at a great rate by underground suckers. It is easy enough to grow in full sun and light soil. O. taraxacifolia, which often dies in the winter but can be easily raised from seed to flower the same year, blossoms up to the frosts. Both of these plants are prostrate in habit, and have large and beautiful white flowers. Zauschneria Californica is an autumn flowering plant with brilliant scarlet blossoms. It also increases rapidly and needs plenty of room. It thrives and flowers best in a hot, dry place. Plumbago Larpentz, also an autumn flowering plant, with fine cobalt blue blossoms, may be grown with it. Aplopappus Brandegei is a little known but valuable composite from America. It is like a minute sunflower, but low and bushy in growth. It flowers from the beginning of July to the autumn, and thrives in any sunny dry place. Most of the Androsaces are spring flowering, but Androsace lanuginosa is at its best in August, and often continues to bloom until the frost. It is also one of the easiest to grow, as well as one of the most beautiful. It likes a deep soil, 2 ft. at least of fibrous loam, leaf-mould and mortar rubble and a fairly cool situation, where its roots can run THE ROCK GARDEN 179 under one rock and its stems trail over another. When the stems get long they should be pegged down just under the surface of the soil, and they will soon root and grow into a large patch. Geranium subcaulescens, a fine mountain species from Greece, a little larger and more vigorous than G. argenteum, also remains long in bloom, so does Lychnis lagascae when the plants are young, and so does Bellis caerulescens, a pretty little daisy from North Africa which requires a warm place. But the best way to ensure flowers in the rock gar- den in the late summer and autumn is to retard the blossoming season of certain plants by treating them as annuals, This is really nothing else but bedding out, and pedants who object to bedding out anywhere will probably consider it impiety in the rock garden. But bedding out is wrong only when it is contrived so as to make plants look ugly; and there is no reason why they should look ugly when bedded out in the rock garden any more than in the border. There are certain beautiful rock plants which will flower the same year from seed, but later than if the seed is sown the year before. Among these are Papaver al- pinus, Linaria alpina, Calandrinia umbellata, Cam- panula caespitosa and C. pumila (the same plant for garden purposes), and Antirrhinum asarina. Papaver alpinus and Linaria alpina will usually flower the same year if treated as hardy annuals; but their flowering may be ensured if they are sown in boxes in a cold frame about the end of March and planted 180 STUDIES IN GARDENING out as soon as possible. This applies also to the other plants mentioned above. They are all very easily raised from seed, and if treated as annuals will come into flower in July and often blossom up to the frosts. Papaver alpinus is a plant so beautiful that it has moved M. Correvon to write a very pretty poem about it. It is like a small and more delicate Iceland poppy. The flowers are white, pink, orange, or yellow, and often delicately fringed. It must be protected from drought and often flowers itself to death, but repro- duces itself freely by self-sown seedlings. Linaria alpina is almost more beautiful. The type has bril- liant purple and orange flowers. There is a variety all purple and one pink and orange. It does well in most situations when it has plenty of light and air. It also often flowers itself to death, but seeds itself almost too profusely. Both of these plants should be transplanted with care and when they are very small. This also applies to Calandrinia umbellata, which likes the hottest, driest places and has flowers of a very brilliant crimson magenta colour, which might be ugly but for their shining silky texture. It should be treated as an annual, as it is apt to die in our win- ters. It does best in very hot, dry summers. An- tirrhinum asarina is a prostrate Snapdragon from Spain with pale yellow flowers. It also likes a very hot place, and will usually survive the winter if planted in a crevice between the rocks and in a soil mainly consisting of rubble. It is a curious and beautiful plant, but not suited for a wet or cold climate. Cam- THE ROCK GARDEN 181 panula caespitosa, the most familiar of Alpine Hare- bells, will thrive almost anywhere, especially if its roots and long suckers can run under a rock. It should not be placed near any delicate Alpines, as it is very encroaching. There are white and pale blue varieties. It is, of course, a true perennial; but seedlings flower later than old plants, and remain in blossom until the frosts. Therefore it is particularly useful when treated as an annual. Campanula carpatica will also flower the same year from seed; but it is rather a large plant for a small rockery. Of all these plants that can be grown as annuals Linaria alpina is the most useful, since it will scarcely smother the most minute Alpines when growing in the poor soil which most small Alpines like, while in better soil and on the north side of the rock garden it grows much stronger and will give the right amount of shade to plants such as the Alpine primulas, Saxi- fraga apiculata, and Morisia hypogaea. It multiplies so quickly by means of self-sown seedlings that it be- comes almost a weed, but its growth is so slight and delicate that scarcely any plant can be harmed by it. There are also some true annuals that can be used to brighten the rock garden in autumn, such as the dwarfest form of Alyssum maritimum and the delicate little Ionopsidium acaule, which, if sown early in the spring, will seed and flower again from self-sown seed- lings in the autumn. Nor is there any reason in the nature of things why Lobelia, a beautiful plant made unpopular by misuse, should not be employed in this 182 STUDIES IN GARDENING way. ‘These annuals and others as small in their growth should be sown or planted in the bare places left by early flowering bulbs, such as Chionodoxas and the spring and winter Irises and the dwarf Daf- fodils. But there are also bulbs well fitted for the rock garden which will flower in the late summer and autumn. One of the best of these is Anomatheca cruenta, a plant like a miniature gladiolus with bright crimson-scarlet flowers, which grows about half a foot high, and which should be planted in spring and lifted for the winter. There are also the autumn flowering Crocuses, such as Crocus speciosus, C. zonatus, and C. pulchellus, all with delicate lilac- coloured flowers, the autumn flowering Cyclamens, and the beautiful autumn Snowflake, Acis autum- nalis, which likes a cool place and very sandy soil. The Colchicums are not so suitable for the rock gar- den, as they throw up very large leaves in the spring; but Sternbergia lutea is a fine plant for large rock gar- dens, and will flower from the end of September al- most up to Christmas. It is sometimes rather a shy bloomer, but seems to do best in warm sheltered places and light soil with a good dose of manure well below the bulbs. It also likes lime. All of these bulbs, ex- cept perhaps Acis autumnalis, are the better for a covering of one of the smaller Stonecrops, so that the ground they occupy need never be bare. THE PROBLEM OF THE HERBACEOUS BORDER ARDENERS often write and talk as if it were quite easy to keep a herbaceous border full of flowers for six or seven months of the year. Now if it were easy, the bedding-out system, with its obvious disadvantages, would surely never have come into vogue; and as a matter of fact it is not easy; indeed, it is probably impossible; and gardeners of the greatest skill and taste do not attempt it. The real problem of the herbaceous border is not to keep it in full flower from April to October, but to prevent it from looking like a spent firework after the first flush of summer bloom is over. Some of the noblest herbaceous plants, such as Larkspurs and Oriental Poppies, have this grave defect, that they become ugly and ragged as soon as they go out of flower, and even with the best cultivation remain ugly and ragged for some time. During this period, since the better grown they are the more space they occupy, they are an ugly blot upon the border, and a border that is filled with plants of this kind may be very splendid for a while, but when half the summer is over it will begin to look autumnal. It is easy enough to have some flowers in blossom in the border so long as there is sun and warmth enough to bring flowers out at all; but a 183 184 STUDIES IN GARDENING border will not look beautiful unless it has that air of prosperity which is attained without difficulty in June, but not in August. Now many borders lose this air of prosperity too early, just because their owners are too eager for a profusion of bloom at the time when flowers are most plentiful. They fill the border with the flowers they like best, Larkspurs, Irises, Madonna Lilies, Poppies, Pansies, Columbines, and so on, and do not consider what is to happen when these are spent. Even if they vary these with later-blooming plants, such as Phloxes and Michaelmas Daisies, they forget the gaps that will remain when their favourites go out of flower. There is a fashion just now for the herbaceous bor- der; but that fashion will not last unless gardeners arrive at a clear understanding of what can be done with the herbaceous border and what cannot, and unless they evolve sound principles for its treatment. Otherwise, sooner or later there will be a reaction in favour of bedding-out, with its long succession of bloom and its persistent neatness and air of prosperity. We are apt at present to think that there is no need for a border to look neat; in fact, that the desire for neatness is a proof of perverted taste. But that de- sire is a natural one, and has always existed. It is quite a modern idea that gardens should emulate the wildness of nature, and one that could only arise among a people to whom the wildness of nature is becoming an unwonted luxury. It is, in fact, the most artificial form of a nature worship that is itself ‘ THE HERBACEOUS BORDER 185 a reaction against excessive artifice; and, like all artificial things, we may be sure it will not last. The desire for neatness will revive again; indeed, it has never died in those who care for the art as well as the craft of gardening; and they should make it their business to solve the problem of the herbaceous bor- der, to combine its variety and profusion with neat- ness and order. Only if they do this will they secure it against a reaction which will lead to the old excesses, to the foolish neatness of carpet bedding, the dull monotony of ribbon borders. There are some gardeners with large gardens who keep different borders for different times of year; and this is an excellent plan if the garden is large enough to make it possible. Indeed, it is the only method that will bring the full glory of every season into the garden. But it is not a method for every one; and most people, even if their gardens are large, have borders near the house which they wish to be beauti- ful during all the months in which the garden can be enjoyed at all. Such borders should be planned sys- tematically and with foresight, and, above all, with a clear understanding that they cannot be all full of flowers from April to October. It is the desire for too many flowers that has produced the worst abuses of bedding out; and only those who have rid them- selves of this desire can solve the problem of the her- baceous border. They must also rid themselves of pedantic prejudices against all plants that are not hardy perennials. No doubt the herbaceous border, 186 STUDIES IN GARDENING if we are to make a fetish of it, should be filled only with herbaceous plants — that is to say, with hardy plants that die down in the winter. But this would mean the exclusion of German Irises, Yuccas, all shrubs, Pinks, and, indeed, all plants that give the garden beauty and interest in the winter; and no one would carry fanaticism so far as that. We will as- sume, then, that our herbaceous border is not to be all herbaceous; indeed, that it is to contain any plants that we can grow and that will contribute to its beauty. The essence of the herbaceous border, for those who are not the slaves of a name, consists in its variety, continuity, and permanence. The best herbaceous borders are full of contrasts both of colour and form; their beauty persists from spring to autumn, and some of it remains even in the winter; while they look as if they had been long established and long cared for. This air of permanence is not easy to impart to a border; indeed, it cannot be imparted by means of herbaceous plants alone or without orderly and syste- matic arrangement. It can only be attained by the use of shrubs and other plants which keep their beauty, or some part of it, throughout the year, or at least through the spring, summer, and autumn. These shrubs and plants should be regarded as the per- manent part of the border design, as the framework to be planned and determined first, after which the more ephemeral details can be filled in. But if shrubs are planted in a border they must be in character with THE HERBACEOUS BORDER 187 the idea of a border, and they must not interfere with the health of the other plants in it; for, after all, a border is not a shrubbery. There are luckily a good number of shrubs, compact in their growth as well as beautiful, not too wide rooting, and so long associated with herbaceous plants that they will not look incon- gruous in a herbaceous border. The best of these are the most familiar, such as Rosemary, Lavender, Lavender Cotton (Santolina), some of the Cistuses, some of the Shrubby Veronicas, and Southernwood, which, however, has this disadvantage, that it does not keep its beauty through the winter. All of these shrubs not only have a quiet beauty of their own, but also serve as excellent foils to more brilliant plants; while some of them, of course, are worth growing for their flowers alone. They should, as we have said, be arranged systematically and so as to make the framework of the border’s design. If they are dotted about at random, a great part of their effect is lost. But while he is planting them the gardener must consider how he can best combine them with the more ephemeral plants, and he must not arrange them so regularly as to suggest hedges. Their chief purpose is to “pull the border together,” to make a kind of permanent pattern that is distributed all over it. This pattern, therefore, must be contrived so that no part of it will be obscured at any time by tall-growing herbaceous plants. There is no use in a well-rounded clump of Lavender if a great Larkspur grows up in front of it. Rather the Larkspur should 188 STUDIES IN GARDENING be masked by the Lavender, so that it is only seen rising behind it in its prime. Those shrubs will make the best pattern and the best contrast with herbaceous plants which are conspicuous for their glaucous leaves; and these should not be used in too great variety. Three different kinds of shrubs, such as Lavender,! Rosemary, and the tall Cistus cyprius behind, are quite enough for any border, even the largest. In- deed, if the tall and dwarf Lavender are used in com- bination, they, with the Cistus, will make an ex- cellent framework for any border. They should be planted regularly, the dwarf Lavender in the fore- ground directly in front of the Cistus in the back- ground, and the taller Lavender half-way back in the intervals. Shrubs so used should never be allowed to grow straggly, but should be kept symmetrical and compact by clipping. If the reader fears that such a regular arrangement of only two or three kinds of shrubs would look monotonous, he should remember that it can be combined, not only with an infinite variety of herbaceous plants, but also with plants of lasting beauty, such as Pinks, Yuccas, some of the Sea Hollies, and the German Irises, which will help to diversify the permanent design. When a border is planned and planted in this manner, the gardener should not be in too great a hurry for an abundance of flowers. His first object should be to get the plants forming his permanent design well 1 Lavender in the United States needs protection, and C. cyprius is not hardy in the Northern States. L. Y. K. THE HERBACEOUS BORDER 189 established and well grown. He should not, there- fore, crowd and smother them while still small with quick-growing herbaceous plants. If he has patience enough, he will do well to give his shrubs two years start of the larger herbaceous plants, for the shrubs will be worse than useless in the border unless they are thoroughly shapely and well grown; and it is very easy to spoil a young plant of Lavender amid the rank summer growth of a rich border. There is, of course, less need to mask the later flowering herbaceous plants with permanent shrubs than the earlier. Indeed, plants like Dahlias, Michael- mas Daisies, and Chrysanthemums may be employed to hide the Larkspurs and Poppies when they have ceased to be beautiful; and the gardener in planning his border should place his tall early-flowering plants behind his tall late-flowering plants, not, of course, in monotonous rows but in a broken though regular order. An ordered diversity is the secret of com- position in a border as in most other things. The eye should not be drawn from end to end by straight lines of the same plants all flowering together, nor should it be bewildered by a mere confusion. It should be conscious of a framework in the design provided by the repetition of certain prominent plants and relieved by diversity of detail. Parts of this framework must, as we have said, be permanent. Other parts may de- pend upon the flowering season of different conspicuous plants, such as Larkspurs, Peeonies, Phloxes, and Dablias, placed at regular intervals. But the design 190 STUDIES IN GARDENING must always be made up of plants conspicuous in some way or another, either in their foliage or in their habit of growth, and the less conspicuous plants should be used only for diversity and contrast. The front of the border, since all of it is always visible, is more difficult to plan than the back, and has an even greater need of permanent features. Many gardeners overlook this fact. They aim at a continuous blaze of flowers in the front of their borders, even when they are content with alternations of flower and leaf- age behind; and the result often is untidiness just where the border ought to be most tidy. It is also a mistake in design to have an unbroken line of bright colour in front of a more varied background, as the eye is then absorbed by the foreground, and can only get away from it by an effort. There is, therefore, an even stronger reason for alternations of flower and leafage in the front of a border than behind, and these alternations should be carefully planned. No plants are more useful as permanent features in the front of the border than the Garden Pinks; and these should not be planted in monotonous rows, but at regular intervals and alternating with other plants such as Pansies, which will remain longer in bloom and will contrast with them both in flower and in leafage. If the ordinary Pansies are used they may be removed after their first flush of bloom and replaced by bedding plants such as Verbenas or Ivy-leafed Geraniums, or any beautiful and low-growing half- hardy annuals. But if the gardener wishes to avoid THE HERBACEOUS BORDER 191 the trouble and expense of bedding out he can alternate his Pinks with Violas or Tufted Pansies, which will, if well treated, blossom for most of the summer and can be cut back when they are spent and straggly. Behind these low-growing plants he can arrange an- other alternation of more or less permanent plants, such as the dwarf Lavender, Santolina, the dwarf Alyssum, Campanula carpatica, Pentstemons, Aquilegia caerulea, and many others. Here, too, he may replace spring with summer flowering plants; and here will be the place for many bulbs, such as the dwarfer early flowering Gladioli, the varieties of Lilium elegans, the May Tulips, Camassia esculenta, English and Spanish Irises, and Montbretias, which should be planted near the more permanent shrubby plants and will be an admirable contrast to them both in growth and flower. Indeed, the secret of the right use of bulbs in a border is to contrast them with plants of a different and more permanent growth. They should never be relied on for the main effect, as they are usually insignificant when out of flower and do not flower very long. So they should be planted in clumps and not in lines, and their position should be determined by that of the plants with which they are intended to contrast. These are only notes upon a large and difficult subject, but it is hoped that they may illustrate some of the principles of border design. THE TREATMENT OF BULBS RITING lately upon the use of bulbs in the border we said that the secret of that use was to contrast them with plants of a different growth. This is also true, we think, of their use in every part of the garden. The beauty of monocotyledonous plants is usually altogether different in character from the beauty of dicotyledonous plants; more simple, fugitive, and strange. Now the term bulb is a vague one, especially as it is used in nurserymen’s catalogues, where it is often applied to any kind of tuberous or fleshy root, whether of a monocotyledonous or a dicotyledonous plant. But in this article we shall use it, not in the narrowest possible sense, but only of monocotyledonous plants with bulbous roots which are dormant for a certain period of the year; and we shall use it thus, not for any scientific reason, but because we wish to suggest certain principles for the treatment of such plants in the garden, based both upon the character of their beauty and upon the habit of remaining dormant for a certain period of the year. The purpose of the old-fashioned treatment of the best known bulbous plants, such as Tulips, Hyacinths, and Narcissi, was to produce a great blaze of blossom for a short time. They were planted by themselves 192 THE TREATMENT OF BULBS 193 in regiments; and when they were out of flower they were taken up to make room for other plants. This treatment took no heed of their individual beauty of form. Each plant was considered only as contribut- ing to a great mass of colour, and certainly these masses of colour were very splendid. But a great part of the beauty of a Tulip consists in its form, in the shape of its flower, the manner in which it carries its flower, and the contrast between the shape and carriage of the flower and the shape and carriage of the leaves. All this beauty was lost when Tulips were arranged in regiments. But, on the other hand, it must be admitted that a single Tulip is too small and too simple in its form to produce much effect in any arrangement of flowers; and this is true also of most bulbous plants; besides this, their flowering period is usually short. Therefore, if we are to make the best possible use of their beauty, we must arrange them so that a great part of that beauty may not be lost in a blaze of colour, but also so that it may not be frittered away by too scattered planting. The best way to do this is to combine them with plants of a very different habit of growth and character of flowers; and of such combinations there is an infinite variety. We have spoken of the difference in the beauty of monocotyledonous and dicotyledonous plants. That difference is a fortunate fact in Nature, by means of which she produces some of her most ex- quisite contrasts; and it is the gardener’s business to observe such contrasts and to base his own ar- 194 STUDIES IN GARDENING rangements upon them. We have said that mono- cotyledonous plants are apt to be more simple, fugi- tive, and strange in their beauty than dicotyledonous plants; and the gardener should attempt to contrast simplicity with complexity, fugitiveness with per- manence, and strangeness with familiarity. This he may do in many different ways. He may, to take one of the most obvious, plant his Tulips among Pansies or Forget-me-nots, so that they will rise through the contrasting carpet of less simple leaved flowers, as Daffodils rise through the grass. A hun- dred Tulips all of the same kind so planted will not lose any of their beauty of form, since it will be em- phasized by the contrasting beauty of the carpeting plants; and it is only by means of an arrangement of this kind that the true beauty of Hyacinths can be seen. Many people condemn them as stiff; and, indeed, when they are planted out in rows by them- selves they are as stiff as a row of Lombardy Poplars. But as the beauty of the Lombardy Poplar only shows itself in contrast with trees of a more spreading growth, so the beauty of the Hyacinth only shows itself in the same kind of contrast. No one would think of growing Bluebells in regiments, because we are all familiar with the manner in which Nature grows them. But the regimental system is even more fatal to the beauty of the garden Hyacinth. This plan of carpeting bulbs with other plants of a very different habit is now very general, but not so universal as it should be. Many people who are de- THE TREATMENT OF BULBS 195 lighted with the beauty of bulbs in the grass will yet grow the same bulbs in beds or borders on the old regimental system, and they do this, probably, be- cause they think it saves trouble to the gardener. It is so easy to fill a bed with Tulips in the autumn and then to lift them when they have gone out of flower to make room for summer bedding. But it is just as easy to combine them with plants such as Pansies, Forget-me-nots, the double Arabis, and many early flowering annuals, which may be removed at the same time to make room for the summer bed- ding. In the herbaceous border, however, the prob- lem of the right use of bulbs is less easy; and yet it is not very difficult. True, there are many bulbs which are best lifted as soon as they die down, and there are others which resent disturbance at the very time when the border may need to be dug over. But both these difficulties may be overcome with a little contrivance and foresight. Take, for instance, the case of bulbs such as Tulips and Hyacinths, which usually should be lifted at least every other year. These may be planted in considerable masses among carpeting plants or in clumps of eight or ten sur- rounded with plants that will contrast with them; and they may be taken up without difficulty when they have died down, and without injuring the plants about them. The arrangement in clumps is best suited to the taller May flowering Tulips and to other tall bulbs such as the Camassias, Gladioli, English and Spanish Irises, Crown Imperial Lilies, most of 196 STUDIES IN GARDENING the true Lilies, and Galtonias. Some of these, espe- cially Madonna Lilies, resent disturbance, and it is the bulbs which resent disturbance that we have learnt to grow in the most beautiful and rational way. No doubt, if Madonna Lilies could be treated like Tulips, they would often be bedded out like Tulips, and all their beauty would be spoilt. As it is, we grow them in the border and treat them like herbaceous plants, with excellent results. We should extend the same treatment to other bulbous plants, so far as their needs will allow. Thus, the May flowering Tulips should be planted in clumps of eight or ten at regular intervals along a border, and if a hundred or more of the same kind—say, of Gesneriana or Picotee —are then planted in the same border, they will pro- duce a brilliant effect of colour just when it is most needed, whether in contrast with flowering plants about them such as Wallflower or Forget-me-not, or with shrubs not yet in flower, such as Lavender or Santolina. And, if necessary, they may be lifted when they die down, just as Wallflowers and Forget- me-not are taken up when they go out of flower, and other plants or bulbs may be put in their place. The contrast between the grey foliage of shrubs, such as Lavender or Santolina or Southernwood, and the brilliant flowers of bulbs, such as Gladioli, Eng- lish and Spanish Irises, and some of the smaller Lilies, is always most effective; and the beauty of the con- trast depends as much upon the difference of char- acter in the plants as upon difference of colour. The THE TREATMENT OF BULBS 197 bulbs, with their fugitive brilliance, seem to have sought the protection of the more enduring shrubs. And this is not altogether fancy in some cases; for Lilies never thrive so well as when they are close to shrubs, not only because the shrubs protect them from frost when their growth is young and tender, but because they like a very rooty soil. Thus, both for horticultural and esthetic reasons, it is well to grow Lilies such as L. Chalcedonicum and L. pom- ponium close to shrubs such as Lavender or Santolina or Rosemary; and both the beauty and the health of the Lilies will be improved by the association. Among such shrubs also may be grown the different kinds of Gladioli, particularly the early flowering ones, which should be planted in the autumn and which will get valuable protection from the shrubs when their growth first appears in the winter. The later Gladioli, if so treated, may take the place of Tulips when they are lifted, and shrubs will be much less dangerous neighbours to them than herbaceous plants which, especially in wet summers, often grow with incalculable rapidity. If bulbs are associated with herbaceous plants the best effect will be obtained where there is the greatest contrast of growth. Thus bulbs which throw up tall straight spikes of bloom should not be planted among herbaceous plants which flower in the same way, but rather among plants of an altogether different habit—for instance, Gladioli among Gypsophilas; Madonna Lilies among the lilac flowered Goat’s Rue (Galega); Orange Lilies (L. 198 STUDIES IN GARDENING croceum) with Erigeron speciosus; Lilium elegans with Linum perenne or Nepeta mussini (Catmint); Tiger Lilies with Eryngiums; Galtonias with the pink Lavatera trimestris, and so on. But in all such com- bination care must be taken not to place bulbs too close to some herbaceous plant that will make a strong growth before they do, and so smother them before they have a chance of asserting themselves. The later and larger growing bulbs are much easier to deal with in the border than the many little bulbs that flower early in the spring and then die down and remain dormant until autumn. It is possible, of course, to lift bulbs like Crocuses, Scilla sibirica, Scilla bifolia, the Chionodoxas, the Puschkinias, and the Muscaris as soon as they are dormant, and to plant them again in the autumn. But it is a trouble- some business; and many of them do better if left undisturbed. Yet, though they make the border beautiful in early spring, they leave blank spaces just when it is expected to be fullest. If they are to be grown in the border they can be covered with Sedum album, which will not interfere with their growth, and which is green all the winter and very pretty when in flower. In this case they must be planted well in the front of the border as the Sedum, if it is to do well and flower, must not be overshadowed by other plants. But, indeed, these smaller bulbs always do best in the front of the border, as they are apt to be forgotten and dug up if they are among large herbaceous plants, and also they do not get the summer sun which most of them need to ripen THE TREATMENT OF BULBS 199 them. It is also possible, of course, to sow some low growing hardy annual over them, especially over the Scillas and Chionodoxas, which like to be planted deep in a light soil. But this is not so easy to manage with Crocuses, which like to be planted just under the sur- face. The best plan of all, perhaps, with these little bulbs is to plant the Crocuses and Muscaris in the grass, where they will thrive, and the Scillas and Chionodoxas and Puschkinias on some sunny bank which they can have to themselves. Such a bank may be carpeted with Sedum with excellent effects. Scilla sibirica may also be grown in the grass, where it is not too thick and coarse; but it usually thrives better under a Sedum. There are the same difficulties to be dealt with in the case of the smaller autumn flowering bulbs, such as Crocus speciosus, Crocus zonatus, and Crocus pulchellus, Sternbergia lutea, and the Colchicums. The last of these will usually do well in the grass where the soil is good and not too dry. The others are best grown like the Chionodoxas in places which they can have to themselves. The autumn Crocuses can be mixed with Scillas and Chionodoxas, so that there may be flowers in the same spot both in spring and autumn. They are of the easiest culture. Stern- bergias are not so easy, and in some places they re- fuse to flower. They seem to require a light soil and a warm sheltered place, and they are the better for lime in the soil. A carpeting of Sedum will protect them in the winter. In most gardens there are odd places too dry or 200 STUDIES IN GARDENING poor for ordinary herbaceous plants in which most of these smaller bulbs will thrive, and where they should be planted in large numbers. Even if such spots are flowerless in summer, it is a great pleasure to have them covered with flowers in spring or au- tumn, and one which is very easily obtained. ENGLISH IDEALS OF GARDENING ARDENING in England, like music in Ger- many, is a national and popular art; and just as music in Germany is based upon folk song, so gar- dening in England is based upon the cottage garden. German music, when it has tended to become arti- ficial or exotic, has been simplified and quickened by a return to folk song, the lasting affection for which has protected the German taste in music from those perversities to which it is subject in other arts. It has provided a standard of simplicity and sincerity by which even the most elaborate compositions are judged, just the kind of standard which Tolstoy has tried to set up in his “What is Art?” And the Eng- lish cottage garden has provided the same kind of standard for the art of gardening, and in the same way has redeemed that art from exotic perversities. When the bedding-out mania was at its height, it was the spectacle of cottage gardens, with their beauty that seemed as natural to the English countryside as the very meadows and hedgerows, which gave people a disgust for their rows of Calceolarias and Geraniums and Lobelias. But for the cottage gar- dens they would never have been even aware of the existence of all the beautiful old plants which had been banished so long from the gardens of the rich; 20) 202 STUDIES IN GARDENING still less would they have been aware of the right manner of growing them. It was because gardening was a national art practised by the poor for love, and not as a fashionable amusement, that it recovered so suddenly from those perversities of taste which infected nearly all arts in the nineteenth century. But it would not have so recovered unless the tastes of rich and poor had been really alike, unless the rich had found in the gardens of the poor what they desired in their own gardens. This is the great dif- ference between gardening in England and in other countries, that in England the cottage garden sets the standard, whereas in other countries the standard is set by the garden of the palace or the villa. And the reason for this is that, though circumstances have made us herd together in towns, we remain at heart a country people, unlike the French or the Italians, and more even than the Germans. This may be clearly seen in our architecture, with which, of course, our gardening, so long as it remains an art, is closely connected. Even in the Middle Ages the great French Cathedrals were designed as town buildings, and made to tower above the houses close about them. But the more lowly English Cathedrals were intended to be seen in broad closes, and half of their beauty is lost without a close, just as half the beauty of a French Cathedral is lost when it is isolated. But the peculiar genius of the English builders has been shown more in village churches and tithe barns and country houses even than in Cathedrals; whereas the peculiar genius ENGLISH IDEALS OF GARDENING 203 of the French has been shown in Cathedral and cha- teaux, and of the Italians in palaces. These inveterate country tastes of ours are, no doubt, the chief reason why our towns are so incoherent and ugly. Our hearts are never in the town, even when we are forced to live in it, and our idea of improving it is to make it as much like the country as we can. Thus our town architecture is always apt to be freakish and incon- gruous, putting on airs of rustic simplicity or medieval romance, trying to make us believe that we are any- where rather than in a modern city; and thus the gardens of our squares are desolate parodies of wood- land and meadow. The foreigner, who has heard of the English passion for gardening, must suppose that passion to be extinct when he looks through the rail- ings of a London square at the thickets of privet and the grass worn bare with the drip from grimy and dis- consolate trees. He cannot know that in these dread- ful places the Englishman has attempted an impos- sible task and given it up in despair; that having an open space in the heart of a town he has tried to per- suade himself that it is a still surviving piece of the country which he loves. A Frenchman would treat such a space as an annexe to the houses around it, as a kind of outdoor parlour common to the inhabi- tants of all those houses, and he would decorate it like a parlour with ornaments, which, whether they were shrubs or statuary or flowers, he would keep in their proper place. Perfectly content with town life, he would have no wish to make believe that he was 204 STUDIES IN GARDENING in the country. Indeed, he would be more inclined when in the country to make believe that he was in the town. Thus his gardening, and also the Italian gardening, is seen at its best in the town and at its worst in the country, unlike ours which is country gardening and will not acclimatize itself to the town. It is true, of course, that the gardening of our parks is excellent, better indeed than any in Paris; but that is just because those parks are large enough to admit of country gardening, because flowers can be well grown, and trees and large shrubs are not mere nuisances in them. The gardeners of our parks have managed with admirable art to make their flowers seem at home where they are planted, an art which the Paris gardeners, skilful as they are, have not ac- quired. Even in towns we are supreme in the manage- ment of flowers, wherever flowers can be well grown; and the reason is that we think of a garden as a place for flowers, whereas for the Frenchman or the Italian it is an outdoor parlour which may be ornamented with flowers or with other things according to the taste of its owner. This love of flowers is part of our love for the coun- try, and consequently it is a love of flowers growing rather than picked. We may compare it with the Italian love of painting, not merely in the form of pictures, but as a decoration to walls, which still per- sist although the great masters of fresco have long passed away and although it is often put to absurd uses. Those who have only seen Italian pictures in ENGLISH IDEALS OF GARDENING 205 galleries can never understand the purpose and full beauty of Italian painting; they can never know what a natural growth it was, until they see the frescoes and altar-pieces where they were meant to be. Such works in galleries are like picked flowers, still beauti- ful indeed, but robbed of half their original beauty because they have been severed from their native soil; and just as an Italian of the fifteenth century would feel if he saw the altar-piece of his native Cathedral in the National Gallery, so we feel when we see the flowers of our gardens picked and arranged in bouquets in shop windows. Foreigners do not usually seem to have this delight in the beauty of growing flowers. They like them just as well picked as growing. Indeed they are apt to grow them so artificially that they have no more beauty when grow- ing than when picked. For them flowers are always mere ornaments, whether of the house or of the gar- den. But for us they are living things with a beauty dependent upon the whole of their life. This love of flowers as living things, and therefore not only of flowers but of plants, is the basis of English garden- ing, the cause both of its virtues and of its faults. It was overcome for a while in the last century and in the ‘gardens of the rich; but it persisted all the while among cottagers; and it is from cottagers that the rich regained it. There are beautiful cottage gardens everywhere in England, because the English- man loves growing flowers for their own sake, as the German loves music; and it is this love of growing 206 STUDIES IN GARDENING flowers which has made gardening a popular art in England. In other countries, where there is not the same love of growing flowers, the palace and not the cot- tage garden sets the standard, and therefore gar- dening is not a popular art; for the poor man cannot hope to compete with the rich in the way of palatial gardens, any more than in the way of palatial archi- tecture. But he can compete with the rich in the growing of plants since he can grow his plants for himself, whereas the rich man must hire a gardener to do it for him. Thus in England many a rich man has envied the beauty of a cottage garden, and tried to imitate it in his own; but abroad little gardens, when there are any, are apt to be imitations of the gardens of the rich; and in Italy or France it is the sumptuous gardens that delight us with their terraces and avenues and cascades, whereas in England we get most pleasure from the little flowery patches and clipped yew hedges and arches by the roadside. For- eigners sometimes wonder how it is that, with all our great poets, our common life seems to be so prosaic. The poetry of the English nature expresses itself in gardens as the poetry of the German nature in folk- song; and by means of gardens it is intimately con- nected with our common life. Once it expressed it- self also in building, and more directly and clearly in the homelier kinds of building than in great cathe- drals or palaces. Once we had a true folk-art in our cottages and farmhouses as well as in our gardens. ENGLISH IDEALS OF GARDENING 207 That is almost lost, although there are now some signs of its revival; but it still persists in our gar- dens and through them it may some day return into our architecture; for the persistence of the cottage garden proves that the spirit which produced the beautiful cottage of the past is still alive, even though the cottage garden may grow up about a white-brick and blue-slated villa. The love of growing plants is the cause both of the virtues and the faults of English gardening. One instance of the faults may be noticed in the desolate gardens of our London squares. These must be fail- ures, as they are attempts to do what is impossible. But in our larger country gardens are often to be found errors of the same kind, though not so fatal. The rich man, who admires a cottage garden and who tries to imitate its beauty in his own grounds, is apt to forget that a great part of that beauty depends upon the fact that the cottage garden is planned to suit its own small scale, that the art of cottage gar- dening has grown up through centuries and has adapted itself perfectly to its own conditions. The conditions of the large garden are different and require a different and more difficult kind of design; while its traditions have been broken by several violent changes of taste, such as the landscape mania of the eighteenth century and the bedding-out mania of the nineteenth. It is certainly possible for our larger gardens to have some of the beauty of the cottage garden; but they must attain to that beauty in their own way, and, in aiming at 208 STUDIES IN GARDENING it, they must not lose sight of the different kinds of beauty that is proper to large spaces. It has often been remarked that, in certain details, such as their porches and west fronts, our cathedrals were designed as if they were little churches; and, in the same way and for the same reasons, our modern large gardens are often designed on a small scale suggested by the cottage garden. The borders are not long enough, the lawns not large enough, the paths too often broken and curved, the shrubs dotted about without any system or purpose. There are other reasons for these defects besides the cottage garden ideal. One is the landscape fashion which has not yet passed away; another is the new fashion for having different kinds of gardens, rock and water and rose, or gardens for different seasons of the year; and another, closely connected with the last, is the growing interest in the more difficult kinds of horticulture, in the culture of plants that require special conditions. The am- bitious gardener nowadays is apt to lose sight of de- sign altogether in his attempts to solve different horticultural problems; and he is the more ready to lose sight of design because he does not understand that a large garden will not look as well as a cottage garden, unless its design, like that of the cottage garden, is adapted to its scale. A large garden can no more imitate a cottage garden than a large house can imitate a cottage. Just as the irregularity which is pleasing and full of character in a cottage becomes incoherent and absurd in a large house, so the ir- ENGLISH IDEALS OF GARDENING 209 regular planting and planning of a cottage garden, which are pleasing when they are made necessary by its smallness, become merely chaotic when they oc- cur in a large space where there is no need for them. Our older garden designers of the fifteenth and six- teenth centuries knew this thoroughly. At their best they could design gardens that were both stately and simple, perfectly suited to the noble houses which they surrounded, and with no pretence to be either wild or palatial. Then, as there were houses fitted for every station of life, so there were gardens fitted for every kind of house. The first invasion of this happy state of things was made by the Dutch fash- ion of over-elaboration and formality against which Marvell protested in some beautiful verses. Then came the French and Italian palatial ideals, which, however, never got much hold in this country; and then the violent reaction of landscape gardening, which ended in a chaos, from which we have not yet emerged. The cottage garden has delivered us from the minor, but most disastrous, fashion of bedding out. It has given us back some of our old delight in gardens, but it cannot by itself give us back the true principles of design. These, probably, can only be recovered with the true principles of architecture. It is certain that garden design deteriorated and fell into chaos just as architecture deteriorated and fell into chaos, also that the present improvement in domestic country architecture has been accompanied by an improvement in garden design. The English 210 STUDIES IN GARDENING love of the country has already delivered us from the worst errors of gardening. It may once again give us beautiful houses, and perfect gardens to suit them. THE NORTH SIDE OF THE ROCK GARDEN T is one of the advantages of a well-planned rock garden that it provides a great variety of con- ditions in a small space. But it requires some knowl- edge of the habits of rock plants to profit by this variety. Most rock plants, and particularly those which grow high up in mountains, are not so adapt- able as the plants of the lowlands. Their power of adaptation seems to have exhausted itself in suiting them to the peculiar conditions of their native homes; and, the more peculiar these conditions are, the less power they usually have of adapting themselves to others. In this they are very like human beings; like the Eskimo who pines away from his native ice and snow, and the mountaineer who is homesick in the plains. Thus, when a rock garden is well placed, planned, and built, there yet remains the further problem of finding exactly the right positions for the plants that are to be grown in it; and the success of a rock garden will depend upon the nicety with which this is done. It is true that there are many rock plants which will thrive fairly well in any open position; but even these will usually do better in one place than in another; and the gardener’s aim should be to have all his plants doing their best. Now, of all differences of conditions which affect 211 212 STUDIES IN GARDENING the well-being of rock and mountain plants, the most important are those of aspect. Of the more difficult Alpine plants, many will thrive on one side of a stone and not on the other, because of the difference of aspect; and even to rock plants which are not difficult aspect usually makes a great difference. It is, un- fortunately, impossible to lay down hard and fast rules about the aspects most suitable to particular plants, because the general conditions of rock gardens vary so much. Some are in warmer parts of the coun- try than others. Some are fully exposed to the sun, others shaded from it to some extent by the lie of the ground or by trees or shrubs. Some are in gardens with a north aspect, others in gardens with a south. Thus a plant that would prefer a full south aspect on a rock garden in a cold climate, might do best with a south-west, or even north-west, aspect when the rock garden was very hot and sunny. There is much that the gardener can learn about his own rock garden only by experience and observation; and whatever general directions are given should be taken as referring only to average conditions, and should be modified where the conditions are not average. But, if a rock garden is well placed and planned and built, not too dry and not too damp, and in particular not overshadowed by trees, there are certain direc- tions about aspect that may be followed without much fear. Thus a south-west or south-east aspect is usually the best for the more delicate plants of the higher Alps, and a full south aspect for those which NORTH SIDE OF THE ROCK GARDEN 213 come from Asia Minor and other hot countries. But, as mountains have their northern slopes as well as their southern, there are many mountain plants that will thrive better on the north side of the rock garden than on the south; and, since many gardeners seem to have some difficulty with the northern slopes of their rock gardens, we propose to give a list of these north-loving plants. First we will speak of those which, although they thrive on a northerly slope, yet require an open situa- tion free from any kind of shade or drip. Some of them also, although they like a northern aspect be- cause it is turned away from the full power of the sun, do not like our north and north-easterly winds par- ticularly in early spring, when they are just starting into growth. There is a great difference between a north aspect that is sheltered by a bank to the north of it, and one that is quite unsheltered. We shall therefore first mention the plants which require shelter, or, at any rate, a north-easterly aspect rather than one facing north-east or full north; for there are many plants that will endure an unsheltered north-westerly aspect but require shelter if they are facing full north or north-east. Of these, one of the most valuable is Lithospermum prostratum, perhaps the most valuable of all rock plants. It will do well on the south side, but even better on the north when it is sheltered from the wind; but it must have light, rich, and deep soil free from lime, and should be placed so that its roots can run under a large stone. It must also have very 214 STUDIES IN GARDENING good drainage, and not be overshadowed by any other plant. It may be interspersed with Arenaria montana which thrives in the same position, or with Saxifraga pyramidalis, which, unlike most of the rosette Saxi- frages, prefers a soil free from lime. Most of these rosette Saxifrages will do well on the north side, espe- cially the great Saxifraga longifolia and the little S. valdensis, both of which dislike a very hot place; but for both of these north-west is better than north- east. Many also of the smaller Campanulas like a north aspect. Indeed, C. pulla always does best on the north side, especially if it is split up and replanted in fresh soil every two years or so in the spring. C. muralis with its larger variety is an excellent plant for a north aspect, and it may be mixed with the beautiful Silene alpestris with the best effect. Other Campanulas that do well on northern slopes are C. turbinata, the dwarf form of C. carpatica, C. Tom- masiniana, a most delicate little Harebell, so small that it must not be put near any large plant, C. Scheu- zeri, C. pumila or caespitosa, and C. garganica with its varieties. This likes a north-west aspect and a very open situation; and it may be mixed with the little Silene acaulis, a native of the Welsh mountains, which is apt to burn up in a very hot sun. Another delicate little plant that will do well with a north-west aspect is Asperula hirta, a Woodruff with pale pink flowers, which roots deeply and spreads fairly rapidly in a well-drained place among the rocks. This also may be mixed with Campanula garganica, or with NORTH SIDE OF THE ROCK GARDEN 215 its more vigorous variety hirsuta, with excellent ef- fect. One of the most valuable plants for covering a large space on a northern slope is Polygonum vac- cinifolium. It is quite prostrate and flowers in late summer and autumn. It grows very quickly, the stems rooting in the ground, and no small plants should be put near it. It flowers best in a rather poor soil and open situation. It should be planted in spring and not disturbed afterwards. Space also is needed for Dryas octopetala, a lime-loving plant, which grows into a large prostrate mass, bearing white blossoms rather like those of a strawberry throughout the summer. Many of the smaller Drabas do well on the north side, especially D. Aizoon, D. aizoides, and D. bruniefolia. Of these D. Aizoon, a native plant and easily raised from seed, is the best. It grows in little rosettes with a head of yellow flowers rising from the centre of them. It is quite easy, but does not like a hot sun. The other two are more mossy in growth and cover a larger space. Another little crucifer with yellow flowers that thrives on the north side is Morisia hypogea. It blossoms very early in the spring and should be planted in a deep crevice, between rocks. When it has formed several crowns it should be divided, and replanted in fresh soil just after flowering. It is a plant to associate with the smaller Alpine Primulas, most of which like a north-west aspect and the same deep crevices. The best of all these, perhaps, is Primula pubescens alba (or nivalis), a small but vigorous plant with pure 216 STUDIES IN GARDENING white flowers in very early spring. Others well worth growing are P. viscosa, P. auricula with its varieties, P. auricula marginata and P. marginata, both of which like lime; P. calycina, also a lime-lover, P. glutinosa, and P. minima. They all like to be closely surrounded with rocks, and the soil should be deep, light, and fairly rich. Atragene alpina, the Alpine Clematis, will do well in a sheltered place on the north side, but it must have a good space to grow in. It likes a fairly rich soil mixed with humus and lime. Near it may be placed Polemonium confertum mel- litum, which has sweet-scented white flowers and grows about 9 in. high. This plant often dies out after a year or two, but it is easily raised from seed and is one of the most beautiful flowers of the Rocky Mountains. Aquilegia pyrenaica, the smallest of the Columbines, also does well on the north side. It is a rare plant, growing only a few inches high, and a form of A. vulgaris is often sold for it. The true plant is well worth growing. Where there is an excavated rock garden many beautiful plants may be grown upon its lower northern slopes. It is in such a position that Ramondia pyre- naica does best, placed between rocks so that its roots run almost horizontally backwards, and so that the sun never strikes upon its leaves. It likes a fibrous soil of loam, peat, and leaf-mould, with a good dose of lime. It is always finest near to water, but will do well without it, provided it gets no sun. Its true beauty is only shown when it is flourishing. Plants NORTH SIDE OF THE ROCK GARDEN 217 that may be grown near it are Anemone alpina, a lime-loving plant, and its variety sulphurea, which dislikes lime, Anemone verna, several Himalayan Primulas, such as P. rosea, P. involucrata, and P. Sikkimensis, Chamaelirion carolinianum, the smaller Dodecatheons, and the Soldanellas.
