What is written is more especially for the large number of people who, though interested in plants and flowers, have little or no knowledge of botany, and neither time nor inclination to acquire it. It is not intended by this statement, however, to give support to a somewhat common opinion that the lessons of botany are useless or uninviting, for few studies can be, to a genuine lover of nature, more attractive or even fascinating. In nearly all cases the popular names of plants are given in connection with those by which they are scientifically known throughout the civilized world. Botanical terms and phrases are employed in description only when it is believed they will interest and assist the ordinary reader, rather than tend to his embarrassment. It is certainly worth something to those who admire trees, shrubs, and flowers to know their scientific as well as their common names, and, to some extent, their origin and history. It is as a help to such knowledge, the want of which is sorely felt by many, that these pages have been written and are now given to the public. Much that is contained herein is gathered from the writings of those who have iii iv Preface. gone before, including recognized authorities whose works are valuable chiefly to those who, like their authors, are learned in botanical studies. But dependence has not been made on these alone. The volume has been pre- pared in Newport, R. I., America’s great summer resort, which in its magnificent villa and cottage grounds is almost literally a city of gardens and flowers. Here per- haps more than anywhere else in America are to be found in practical use the combined horticultural treasures of the world. These famous gardens derive their chief beauty and glory from what are known as hardy plants. In almost every instance the chief reliance for both flowers and foliage is upon shrubs and herbaceous perennials. The author has improved the opportunity of studying the pro- cesses of growth and cultivation on most of these estates from their inception to their present proportions, and is thus able to write largely from personal observation and study of the living specimens in all stages of their growth. Here are to be found the newer as well as the older hardy exotics from all parts of the world, where such have been grown alongside our native plants and their relative merits fully determined. All those which have withstood the tests of experience are here brought under review, and their especial characteristics noted so far as practicable in the space allotted; it being the purpose to cover the whole field especially of the hardy shrubs, old or new, adapted to useful and ornamental planting. It is well understood that botany deals chiefly with fixed forms, as represented by orders, genera, and species, Preface. Vv and that it takes little or no note of such varieties as are constantly making their appearance throughout the world. For this there is good reason from a scientific standpoint, but when it comes to the practical use of plants in general cultivation it is found that many of the species thus treated have given forth varieties, through processes well understood, that are far more valuable for the work in hand than the originals, and such as are com- ing, in a large measure, to displace them. A very large proportion of the plants in the best gardens of Europe and America belong to the latter class, many of which are not even named by the scientists—much less described. To these especial attention is given, as for horticultural purposes they are of great value. It is true that much has been written in a fragmentary way concerning these varietal forms, but this is believed to be the first attempt to gather and publish in a single volume an account of the wonderful evolutions in connection with the several types so far as they are of practical use in our gardens and parks. There are also many excellent books in the hands of the people, or at their command, treating of the plants of certain sections of the world, each complete in itself, but regardless of their value in horticulture or of the uses to which they may be put. All this is in the direct line of scientific inquiry, and such books are of the highest possible value, but fail to meet the call for information which comes from the man with grounds to plant, and who is neither a botanist nor versed in horticulture. Though the attempt is here made to describe in brief the desirable forms indigenous to other countries as well vi Preface. as our own, so far as they are in use among us and appli- cable to the wants of American horticulture, there will still be left large possibilities for the future. New varie- ties are springing up and new forms appearing every year, both by natural processes and through the skilful work of the hybridizers and gardeners, who are ever on the look- out for new things in this line. These processes will go on in the future as they have in the past, and it may well be believed that the possibilities are limitless in this direction. Acknowledgments are due to Messrs.

HE kalmias, or laurels, are among the most beauti- ful plants in cultivation. ‘They constitute a small genus of the order Z7zcacee, which was named by Linnzus in honor of Peter Kalm, who was at one time his favorite pupil, and, later, a traveller and distinguished botanist. They are all of American origin, and may be found over a large extent of territory ranging from Canada to Florida. But five or six species are known, and not many established varieties, though there are some forms so near the border between the two as to make it difficult to draw the line with certainty. K. latifolia—Calico Bush.—This is the well-known mountain laurel, which is indigenous to New England and even much farther north, and may therefore be put down as perfectly hardy and easily grown throughout the north and northwestern States and Territories. It is found high up among the New Hampshire mountains and often in most inhospitable situations, as well as upon the Alle- ghany ranges and Georgia hillsides. In protected situa- tions, it sometimes grows to a height of fifteen to twenty I 2 Ornamental Shrubs. feet, but as usually seen, its proportions are very much less. It has a slender stem, with branches in twos or threes in imperfect whorls. The leaves are scattered, though often in tufts, from two to four inches long, rather narrow, acute at each extremity, glossy green, coriaceous, and continuing during the winter even in the coldest cli- mates. Few or no plants produce more lovely blossoms, which appear in June and July, and in thus follow- ing the rhododendrons and most of the azaleas, are of the most effective service in keeping up a succession. , They are in terminal heads on flower stalks an inch or more long, Whey colonmen the corolla varies from a pure white to a rich rose, with numerous shadings be- BROAD-LEAVED LAUREL.

The wonder is that a shrub of so great hardiness and such charming flower is not planted much more largely than it is. It is more easily grown than the rhododendron and is in no- wise less desirable. It is suggested that the difficulty ex- perienced in removing plants from the woods to private grounds, and the many failures in that direction, have created the impression that it is unusually fickle and cannot be depended upon. But, asa matter of fact, it is no more so - Kalmia—Mountain Laurel. 3 than numerous others of the best and most common plants in our gardens. If one will go to the nurseryman instead of the woods, he will find very little difficulty in this direc- tion. Kalmias properly grown and trained yield as kindly to removal as do most other plants, and can be handled as safely. Nicholson pronounces this ‘‘one of the most useful, elegant, and attractive of dwarf flowering shrubs.” XK. angustifolia, or narrow-leaved laurel, is a low ever- green plant, usually from one to three feet high, and is often found growing in bunches or paths in moist or low grounds, where it is deemed especially undesirable by the farmer or herdsman who considers it poisonous to calves or lambs. So common is this impression that in many sections it is known as the lamb-kill or sheep-kill plant. It is claimed by some good authorities that the foliage is not poisonous at all, and that the ill effects ascribed to it come from the fact that the foliage is quite indigestible, and thus fatal at times to young and tender animals. This is all the more probable from the fact that we seldom or never hear complaints of fatalities in the case of cattle or sheep of mature years, which, it is to be presumed, feed on the leaves as freely as do their young. In this little shrub the flowers are in lateral corymbs, and in from three to twelve whorls to each spike. They are purple and crimson, and appear in early summer. The London Garden says that K. angustifolia should always be planted in rhododendron beds so as to keep up a suc- cession of flowers, and mentions three sorts which may well be used for sucha purpose. There are several pretty varieties, one of which, the zavza, makes an excellent pot 4. Ornamental Shrubs. plant. It grows but six to eight inches high. A. glauca is another dwarf of from one to two feet, having lilac-pur- ple flowers, and leaves with revolute edges, long and narrow, green on the upper side and glaucous white be- neath. It is a handsome little shrub, and can be used to advantage in many situations. A. /zrsufa is an extreme southern species, ranging from South Virginia to Florida, and is said to be found also on the island of Cuba. The flowers are rose-colored, and appear later than the others. It is not of much worth, however, for garden purposes. DEUMIAVA: HE deutzias constitute a genus of the order Saxz- frageg@, and are mostly natives of Japan and the Himalaya Mountains, though it is believed that they are also indigenous to northern China and perhaps other portions of Asia. None of the species is found in Europe or America as native of the soil. They received their name in honor of Johann Deutz, a Dutch naturalist, whose memory as a botanist is thereby carried to succeed- ing generations. Nearly all are hardy shrubs, with rough bark, axillary flowers, and leaves mostly ovate, acuminate, serrate, and more or less scabrous. Though hardy, some of the smaller members of the group are suited to forcing under glass, by which process they are made to produce beautiful flowers at any season of the year desired, and in great abundance. When introduced to Europe they were received with much favor and were soon widely dis- tributed, as was also the case in our own country, where they still occupy an important place in garden and park Deutzia. 5 planting. The genus is not large, but the number of varieties is constantly increasing, some of which are in marked distinction from the type. D. crenata is now described as the type from which several others, heretofore classed as distinct species, are recognized simply as varieties. It is a fine shrub six to eight feet high, and often throwing up several stems from the same root, the whole forming a well-proportioned head quite as broad as its height. The leaves are ovate-lanceolate, serrulate, somewhat rigid or stiff, and Tough to the touch. The flowers are white, in racemes or panicles, and very pretty.
