Ir is well known to all concerned with horticultural exhibi- tions that a much felt want has long existed of some definite and systematic standard by which the merits of exhibits might be measured with a fair amount of accuracy. In this treatise I have endeavoured to meet this want by giving the details of a simple and efficient system, which can be applied on all occasions, and varied in detail to suit the wants of every case. A Handbook of concixe hints and cultural notes on the rearing and preparation of specimens for exhibition is also a desideratum among horticulturists, especially amateurs and those of limited experience. The cultural remarks in this work will therefore, I hope, be of some practical service to such aspirants to sticcess, and enable them to attain their object with less trouble and more certainty. In the Plant and Cut Flower Divisions of the work I have received valu- able assistance from several eminent growers, for which I beg to express my warmest thanks. Further, I am very specially indebted to Mr. Duyy, Dalkeith Gardens, for his kind assistance in revising the volume; but for all matters of opinion referred to in it, the Author is alone responsible. vill PREFACE. In referring to the various genera and species of plants, the names by which they are commonly known in horticulture are generally employed, and no attempt has been made to follow any system of botanical nomenclature. I trust the work may fulfil the objects aimed at, and form a standard for estimating the merits of exhibits with some degree of precision and regularity, and thus lead to an all-round advance in Horticulture generally. Ww. W. March 1892. INTRODUCTION. Ix introducing the reader to the contents of this Handbook, we consider it necessary to give a few general remarks on exhibitions ; to point out some of the benefits they confer on those who participate in them, and show the effect their agency has on increasing the value of produce. Exhibitions, whether of Science, Art, or Industry, are usually inaugurated with the view of promoting one or more of such desirable objects as the education of the public mind, the gratification of the senses, or the encouragement of Science, Art, or Commerce. That the desired results have been attained in a marked degree in Horticulture is clearly apparent to all observers. When we notice the large and increasing number of shows held throughout the country, nearly every parish and village participating in the annual display of garden pro- duce, and see the interest taken in their success by all classes of the people, we are led to conclude that flower-shows must be doing a vast amount of good, directly and indirectly, in this country. Whatever tends to increase the productiveness of the soil—whether it be the proper application of labour, or the acquirement of a sound knowledge of the wants of plants, and the best modes of applying the elements provided by Nature and Science, to meet the varying demands of plant life—is assisting in a material degree to furnish the means which so largely contribute to the comfort and happiness of the people. There can be no doubt whatever that exhibitions tend in this direction, The inducements offered through their agency have a stimulating effect on the mental and physical energies of all who participate in competitions, which are in themselves x INTRODUCTION. laudable and interesting, when conducted in the right spirit, and with due regard to the rules and regulations imposed by all well-ordered societies. Sometimes these laws are set aside by individuals, who do not hesitate to acquire by illegitimate means any article of which they may be in want; but there can be no veal satisfaction to the mind of any one gaining a prize with what is not his own bond jirle production, and the spirit which prompts this dishonourable practice should be combated by all competitors. It is to be regretted that so few professional gardeners avail themselves of the opportunities for distinction in the art of Horticulture provided for them by the numerous and influential societies throughout the country. Many reasons may be given for this lack of zeal and interest in such competitions. The proprietor may not approve of exhibiting, und in that case the gardener has no choice in the matter. But in a large number of non-competing gardens things might be different if it were generally known how beneficial a reasonable amount of successful competition is to all concerned, especially in the now numerous class of gardens where the surplus produce has to be disposed of in the market. Apart, altogether, from the general effects of the extra attention, application of skill, and the unsparing energy in manual labour, at all hours, which successful competition entails, there is a decided increase in the value of the produce, which is well illustrated by the fol- lowing incident of actual experience. A few years ago two places were sending equally good grapes to the same fruit merchant, but the money returned to the one was about double that given to the other. .An explanation was demanded, and, while admitting that the grapes were equally good, the dealer said the grapes from the one place had got a name in the town, and brought a high price, which was explained by suc- cessful competition in the one case and non-com petition in the other. A common objection raised to growing fruit for com- petition is that the plants are under-cropped. This may occur through ignorance or inexperience in reducing the crop to less than what the plant is well able to mature. It should be clearly understood, however, that there is no loss in growing INTRODUCTION. xi fruit to what may be termed the exhibition standard, that is, the highest state of perfection to which it can be brought. This can only be done by inoderate cropping, or just what the plant with good management is able to sustain and perfect. When more than this is attempted, then waste begins, first in inferior produce, and ultimately in the premature sterility and decay of the plant. Another prolific source of non-competition is the belief of many that their place is not adapted for the growth of exhibition specimens; but it should be borne in mind that numerous difficulties have to be surmounted in all cases where growing for competition is carried on, and that if soil and situation be unsuitable for one class of plants, they may be well adapted for the cultivation of others, which may be profitably and successfully grown. Thanks are due to thoxe who come forward with high-class exhibits, and thus keep up the standard of perfection in all divisions of horticultural produce. Within recent years great excelleucy has been attained in fruit and vegetable culture. That this has not been altogether the result of improved varieties needs little demonstration. It will as readily be admitted that it is mostly the outcome of an increased knowledge of the best methods of culture, and a better acquaintance with the science which unfolds to us the hidden treasures of Nature. It is matter for regret that so little has been done till quite recently to promote the study of Science as applied to Horticul- ture; and while we hear much about the establishment of schools for educating and training youths in the science and art of other branches of rural industry, such as Agriculture and Forestry, very little has been said in reference to the equally strong claims of Horticulture. When the arrangements are being carried out, it is to be hoped that hint Heslignal science will not be over- looked, as it is quite as important a factor in the prosperity of the country and the welfare of the people as any other branch of rural economy. The need for a.test-examination in Science and Art is fully as great amongst gardeners as it is ng the members of any other branch of the industrial pro- Those who passed successfully would be the better amo fessions. Xil INTRODUCTION. equipped to reap the reward of their industry and natural ability, while others who failed would be relegated to their proper sphere in the horticultural profession. Various associations are doing their best in several parts of the country to make up, in some degree, for this crying want, by offering inducements to young gardeners and others to compose essays on horticultural subjects, for which they are awarded prizes and certificates. These, however, are a very indifferent substitute for a properly equipped curriculum, which would enable them to obtain a thorough knowledge of the theory and practice of horticulture, and thus be the better able to understand and _ successfully overcome the many difficulties which beset the young and inexperienced. Horticultural exhibitions are valuable object-lessons to the aspiring but uninitiated tyro, and form an excellent medium for learning what can be attained towards perfection in Horti- culture by a diligent application of skill and industry. So far as the circumstances and his knowledge will allow, they furnish to the intelligent student a good criterion of the various points of merit in the different classes of exhibits. This phase of the subject is, however, capable of much improvement. The re- mark is often heard at flower-shows, “‘ Why has the prize been wwarded to this in preference to that?” and such questions may, as a rule, be but the outcome of ignorance on the part of the general public ; but the fact must be remembered that the exhibitors are often as ignorant as the others of the relative value of the points upon which the awards have been decided, as no data of any value exist for their enlightenment. One of the chief objects of an exhibition is the all-round improve- ment of the articles exhibited, which we may safely say has been always kept in view and fairiy well accomplished by hor- ticulturists. Most intelligent people do not now visit flower-shows for the sole purpose of merely admiring gigantic and beautiful specimens, similar in most respects to those they have so often seen on the same occasions in every part of the country, but to scrutinise and note the various points of merit which one exhi- bit displays over another, and for the possession of which it has INTRODUCTION. xiii been awarded the premier place. In this, however, they as a rule can only find partial enlightenment, as the judges make the awards from certain features in the exhibits which are, we are willing to believe, perfectly clear and intelligible to them, but of which people in general have only the faintest idea, and no means have existed hitherto by which they could be guided in their search for information on the subject. A simple and efticient method of estimating the value of the merits of all classes of horticultural products met with in competitions, has long been a desideratum to all who are interested in the success of flower-shows, by which an equit- able value could be put upon the skill, and taste, displayed in the culture of every exhibit, and the awards made in accordance therewith, on lines clearly defined and intelligible to all who choose to learn. In estimating the value of Cultural Merit, which is the principal factor in determining awards to horticultural products, it is really an impossibility to frame a code of laws, or lay down rules which could be followed with success in every case, because no two specimens or samples are found to be exactly alike in every detail. Still by means of the decimal system—a simple method, eminently well adapted for the purpose—a close approach can be made to absolute accuracy in valuing the merits of exhibits, and to practical uniformity in adjudicating thereon. After summing up the value of the cultural merits dis- played by the articles in competition—the result of the thought, skill, and taste of the cultivator—it is not advisable, and is seldom needful, to go farther to find data for determining an award ; but in the event of a tie occurring in the cultural value, resource must then be had to the Natural Merits or intrinsic value of the exhibits to determine the award. It is practically impossible to define the relative value under all circumstances of natural merits, because they vary with the tastes and customs of every country and parts of a country, so that what may be highly prized in one place and period may be counted of little use or value at another. Instead, therefore, of attempting to lay down any fixed rules, which in the nature of things could not be of general application, some XIV INTRODUCTION. illustrations are given below of the order of precedence in which the different kinds of exhibits are generally accepted, and which can be easily rearranged to suit the varying taste and cireumstances on all occasions. With these desiderata provided, there is still plenty of scope for the exercise of knowledge, acumen, and sound judgment in making a correct adjudication. It is chiefly in the plant and fruit divisions, where, in mixed collections, the greatest difference in natural merit prevails. The intrinsic, or commercial worth of an article, should not alone determine its relative value in competition, but the greatest weight ought to be attached to the careful persever- ance, skill, and taste required to produce a perfect exhibition specimen. For example, the Croton and Palm, which require several years of careful culture to form specimens, should be allowed more competitive value than a Caladium or Coleus ; and among flowering plants, the Erica and Ixora should have more weight than a Cineraria or Begonia. A greater dif- ference, however, is generally found in relative value among the fruit in a large collection. The Pine-Apple is usually assigned the first position, closely followed by the Grape, with the Melon, Peach, Nectarine, Fig, Apricot, Pear, Plum, Cherry, Apple, Strawberry, Gooseberry, Raspberry, and Currant in the order in which they are here given. Other less common fruits may intervene, but the order of precedence can always be settled on the spot by competent judges, when they have the exhibits before them. In all cases, excellence for dessert or culinary purposes should carry more weight than mere appear- ance or rarity. Rich flavour, high quality, and pleasing appearance, should prevail in dessert fruit; in culinary fruits, large size, even outline, fine flavour, and usefulness, are the chief points. ELECTING JUDGES. THE greatest care and discrimination should be exercised in selecting the judges for horticultural exhibitions by those whose duty it is to appoint them, because the success of an exhibi- tion depends greatly on the confidence with which the awards are received. A common practice is for a committee, or the managers of a flower-show, to appoint the judges from among their horticultural neighbours, without much consideration as to their qualifications for performing the important duties intrusted to them, in a just and equitable manner. Exhibitors quickly find out any defect in the knowledge, fairness, or want of impartiality in the judges, and promptly resent it, thus lead- - ing to much discontent and angry feeling, where nothing of the kind should ever be heard of, if due precautions are taken. Where the selection of the judges is left to the secretary alone, as it sometimes is, the duty may be faultlessly performed by an able and clear-headed man, but, as a rule, this is not a satisfac- tory method of selecting them. We believe that the greatest confidence would be secured if the judges were nominated by a much wider constituency than is the custom at the present time. It is already the practice at some agricultural and other exhibitions to employ judges who have been nominated for the office by the exhibitors, and this method is generally found to give satisfaction. A similar method could easily be adopted in connection with flower-shows. When the prize schedule is issued to the members, a form should be sent out with it, and all competitors requested to fill in the names of competent judges of the classes in which they intend to com- pete, and in due course return the form so filled to the secre- tary of the society. The committee would then only have to find out those who had received the most votes, and elect them xv b xvi ELECTING JUDGES. to the office. Of course, difficulties may crop up in carrying out this method; but where it has been tried, it has generally resulted in the appointment of judges satisfactory to the main body of competitors. The best-qualified judges of the merits of any particular class of exhibits are, as a rule, to be found among those who have devoted themselves to the study aud cultivation of that class, and have been successful in bringing it to the highest state of perfection. It is scarcely possible for any individual in an ordinary lifetime to acquire a thorough knowledge of all the merits, peculiarities, and details of every subject brought under review in horticultural exhibitions ; therefore, in judging the various classes at a flower-show, a division of labour is absolutely necessary. Some men devote themselves mainly to florists’ flowers, sparing neither time nor means to secure varieties with the finest form, colour, and substance, and to cultivate them to the highest possible state of perfection. To this class of horticulturists, therefore, we naturally look for the best judges of the merits of the florists’ flowers. Other men are specialists in the cultivation of certain classes of plants, having by a long course of experience and the exer- cise of trained skill acquired a thorough knowledge of the varied wants and peculiarities of the subjects under their charge, which is needful to ensure success in their treatment, and the production of perfect specimens at the proper time. It is obvious that men so trained should be the best qualified for adjudicating on the various classes of plants. Then, again, other men find themselves perfectly at home among fruits and vegetables ; and from long and careful prac- tice in their successful culture and close study of their various wants, they are thoroughly acquainted with every merit and peculiarity that fruits or vegetables possess. They have thus come to be recognised authorities in these branches of horti- culture, and should be the best qualified to adjudicate on their merits. From the great difficulties in the way of most men acquiring a perfect knowledge of every department of horticulture, so as to enable them to adjudicate with confidence and to the general ELECTING JUDGES. XVili satisfaction in all, it would probably be more satisfactory for societies to appoint one man as the sole judge in the section to which it is well known he has given special attention, and to strictly confine his duties to that section. One thoroughly qualified man would do the work quite as well, probably better, and more expeditiously than the usual triumvirate now in vogue, and the great responsibility incurred would add to the weight of his decisions. The very cream of qualified men may be employed to judge, and their awards may be made with the utmost fairness and impartiality, but still their decisions may appear in the eyes of the uninitiated to vary so widely, as to render them a source of much dispute and dissatisfaction. This arises mainly from the absence of any code or recognised system of judging horticul- tural exhibits. Under the usual arrangements practised by societies at the present day, each arbiter is a law unto himself, and the methods of estimating the merits and demerits of exhibits are as numerous as the judges ! In adjudicating upon the merits of a collection of fruit, for instance, it is a common practice for the judges to begin by allowing three, or it may be four points as the standard of value of the Lest dish in the collection, no matter how nume- rous and varied the dishes may be. The highest number of points, say four, is given to a first-rate Pine-Apple, three to a dish of first-class Grapes, two to a fine Melon, and one to an excellent dish of Peaches, when the scale is exhausted, and nothing left wherewith to gauge the merits of the other kinds of fruit in the collection. Another common practice is to allow a uniform value to all kinds of fruit, Gooseberries and Grapes being placed on the same level. A much more unsatis- factory method is followed at times, when the judges compare the dishes of the same kind of fruit, and thereby determine the awards by the greatest number of “ best” dishes, but taking no account of the aggregate merits of all the dishes in each collection. Worst of all, some judges, after a cursory survey, “slump the lot” in making their awards; and to save their life, they could not give a detailed and satisfactory explanation of the conclusions they have arrived at. xviil ELECTING JUDGES. From these familiar illustrations of the crude methods and unsystematic manner in which judging is practised, especially at provincial shows, the need for reform will be at once ad- mitted, not only in the modus operandi, but more particularly in the general adoption of a simple and easily applied formula, by which a fairly accurate and uniform estimate can be made of the various merits of all classes of horticultural exhibits. It is in the interest of every Horticultural Society to secure the services of thoroughly experienced judges. With local societies this is often a matter of difficulty, and their best efforts may fail to command able and experienced men; but with a clear and simple method of procedure as a guide, the merest tyro at adjudicating may, with the exercise of ordinary intelligence, soon succeed in doing justice to the merits of the exhibits placed before him for his verdict. JUDGING. It should be the aim and desire of all exhibitors to set up their specimens in the most perfect condition attainable, and with all the tasteful effect which their skill and experience can devise, so as to have the best possible chance of winning the highest awards in competition. The merits of every specimen should be brought out ta the highest perfection by the skill and taste of the cultivator, and exhibited when they are in their most perfect form. Without going into elaborate details on the specific merits of every class of horticultural exhibits, with all their varied characteristics among plants, flowers, fruits, and vegetables, with which all properly qualified judges should be perfectly familiar, the chief points of merit in each class will be pointed out in its place in this work, when the subject is dealt with. In ordinary practice, competent judges have seldom any diffi- culty in arriving at a fair and just conclusion as to the respec- tive merits of the exhibits, after a close examination of the specimens. Where, however, they may differ in opinion, or where the competition is keen and close, the following simple and easy method may be adopted in estimating the merits of the individual specimens, and thereby settling the order of the awards to the satisfaction of all reasonable persons. For example, say nine exhibitors are competing in a class of Twelve “distinct” Stove and Greenhouse Plants, or the same number Rose-Blooms, Dishes of Fruit, or of Vegetables, for which three prizes are offered. On careful examination, it is found that four of the collections are clearly out of the running, and may be passed without further comment. The merits of the other five collections are so nearly equal that it is resolved to esti- mate the value of the individual specimens to decide the order iN xx JUDGING. in which the prizes are to be awarded. Taking them as they come, the collections are marked A., B., C., D., and E., and, taken in the same manner, the specimens in each are numbered 1 to 12; and the value of each article estimated and recorded separately, as shown in the following table. The decimal system is employed as the simplest and best for the purpose, and the values are estimated in tenths and hundredths, the standard being the unit, denoting a perfect specimen. | Speci \ | B € D.

Each specimen is minutely examined, and the value of its merits agreed upon, and then noted opposite its number in A. column, and so on until the merits of the twelve specimens have been carefully estimated and recorded. The B. collection is treated in exactly the same manner, and the C., D., and E. collections follow in their order. At the conclusion the results are summed up, and show at a glance that C. collection is first, E. collection second, and B. collection third, with the other two clearly in the rear but not far behind, proving that the competition was close, and showing the necessity for minutely estimating the JUDGING, xxi value of every detail. In the rare event of a tie between two or more of the collections, a more minute examination of the specimens in them, and the extension of the decimal to three figures, will to a certainty decide the closest possible com petition. THE HORTICULTURAL EXHIBITORS’ HANDBOOK. ——— DIVISION L PLANTS. Puayts constitute the main feature in all horticultural exhi- bitions, occupying the greatest amount of space, and provid- ing an imposing and attractive display for the admiration of the public. In treating of the various classes of plants, we have taken them in sections with some natural affinities, and in much the same order as they usually appear in the schedules of flower-shows, as follows :— Section 1. Stove Flowering Plants, Stove Foliage Plants, . Greenhouse Flowering Plants. Greenhouse Foliage Plants. Orchids. Ferns. Palms. Table Plants. Miscellaneous Exhibition Plants. MIS OO o9 by = The genera in each section are taken in alphabetical order, for easy reference. Mention is made, when necessary, of a few of the best species and varieties for exhibition purposes. The cultural remarks are confined as much as possible to the special points requiring attention in growing specimens for exhibition. A to STOVE FLOWERING PLANTS. SECTION I. STOVE FLOWERING PLANTS, ACHIMENES, This is a beautiful genus of soft-wooded, tuberous-rooted stove plants, chiefly from the tropical parts of America, which, from their floriferous nature, make excellent specimens, under good treatment, for exhibition. Among the numerous varieties in cultivation, the following are vigorous and free-flowering, and may be chosen for exhibition :—Carminata splendens, Lon- gihtora alba, L. major, Rosea magnifica, Purpurea elegans, and Williams. The tubercles should be started in a strong heat in a light compost of fine leaf-mould and sand. When the shoots are about an inch long, the plants should be carefully transplanted into pans 12 inches in diameter, placing the plants 2 inches apart, in a mixture of fibry loam and peat, with a third of silver sand and well-dried and broken-down cow-manure, all thoroughly incorporated together. A moist and genial tem- perature encourages vigorous growth, and a judicious use of weak liquid manure, after the pan is full of roots, induces abundance of fine large flowers. As the shoots grow, they must be carefully staked and trained as near as possible in the shape of a half globe. When the flower-buds begin to appear, the plants should be removed to the warm end of a greenhouse, and be gradually exposed to air and light as they expand, In preparing them for exhibition, the horizontal side shoots may be untied and carefully drawn towards the centre, and wrapped in cotton-wool and tissue-paper to carry them safe to the show. They must be again neatly arranged and tied-out, taking care to have the plant well balanced, and every flower fully exposed ; all stakes and ties being well hidden by the foliage. STOVE FLOWERING PLANTS. 3 ALLAMANDA. All the species of this lovely genus of stove climbing plants are of easy culture and remarkably free flowering. They are natives of the tropical regions of South America, and luxu- riate in abundance of heat and moisture. Among the best for exhibition are A. grandiflora, A. nobilis, and A. Schottit. To grow them well for this purpose, the shoots should be run up as near the glass as possible till the flowers appear, when they should be brought down and carefully trained over a balloon or other trellis, securely fixed to the pot, taking care to leave sufficient room to allow the leaves and flowers to assume a natural position. The Allamanda grows well in a compost of equal parts of sound fibrous loam, leaf-mould, and sand, sprinkled with charcoal nodules and half-inch bones. When the specimens are fully formed, and occupy large pots or tubs, it is not necessary to re-pot them annually. With rich top-dressing and a due application of liquid manure, they may be kept in a thriving and floriferous condition for years, Before starting them in spring, the surface soil should be removed to a depth of three inches, and the space filled up with a rich mixture of turfy loam and dry, well-rotted manure, pressed firmly down. The plants require a good rest to ripen their growth, and should be kept comparatively dry through the winter. The shoots should be cut back to a few eyes before the plants are started in spring; and when they break, no more shoots should be allowed to grow than is actually required to furnish the specimen—a few strong and well-matured shoots giving much the finest crop of flowers. Allamandas are usually increased by cuttings which strike and grow easily; but A. grandiflora thrives best when grafted on a stronger growing species, such as A, Schottit. If the specimens have to travel a distance to the show, it is very advisable to gum the flowers, by dropping a little good liquid gum on to the base of the petals, which will prevent them being so easily shaken off in transit. Hach flower should also be carefully wrapped in tissue-paper and cotton-wool, to 4 STOVE FLOWERING PLANTS, save it from being rubbed and injured. When the plants have reached the exhibition, they must be carefully unpacked, and the shoots, leaves, and flowers all neatly arranged in as natural and effective a manner as possible, taking care to leave nothing untidy about them in the way of tying or packing material, and all stakes and ties used in training should be kept well out of view. These remarks as to “ packing ” and “ setting up” of exhibition plants apply to all sections. The finest of specimens are easily ruined by carelessness in packing or in transit to the exhibition ; and a prize is often lost by good specimens being set up in a careless, untidy, and tasteless fashion. AMARYLLIS, This is a beautiful genus of bulbous plants, the varieties of which have of late been greatly multiplied and improved. There is quite a host of fine varieties in the trade, from which the exhibitor can easily select the most suitable for his purpose. The practice of some growers is to turn the bulbs out of the pots after they are matured, and dry them off, while others allow them to remain, and start them without re-potting. As the strength of the future plant depends more upon the perfect maturation of the bulb than on the subsequent treat- ment, the result of the different methods may be imperceptible ; but we prefer to allow the bulbs to rest in the pots till the time for starting, when the old soil is shaken away, and three well-ripened bulbs are placed in a 10-inch pot, using a compost of rough fibrous loam, old hot-bed manure, and sand. They should be started in a temperature of 55°, or a little higher, according to the time they are wanted in flower.’ Little water should be given until growth is proceeding. When the flower- scapes appear, the plants should be taken to the greenhouse, placed near the glass, and watered with weak liquid manure to assist in the full development of the flowers. The flower- stems should be securely staked, the flowers enveloped in wadding, and the leaves carefully laid up against each other, when removing the plants to the exhibition. STOVE FLOWERING PLANTS. 5 ANTHURIUM, Perhaps A. Andreanum and the well-known species 4d. Scherzerianum are the two most popular of this genus with exhibitors, and have a bold and striking appearance in a group of flowering plants. They are of easy culture, and owing to the firm texture of the leaves and flowers make splendid exhi- bition plants. They luxuriate in a high temperature with plenty of moisture in the atmosphere. During active growth they must have copious supplies of water at the roots, while a little fish-manure dissolved in water and applied once a week during summer will be found a healthy stimulant. The proper time to re-pot them is early in spring, or when growth has commenced. The pots should be one-third full of crocks, and the compost used should consist of very fibry peat, charcoal, and spagnum ; keep the plants well above the rim of the pots to ensure perfect drainage and a free circulation of air about the roots. BOUGAINVILLEA. This is a beautiful genus of stove flowering plants of climb- ing habit, blooming in summer on the points of the current year’s growth. They must be trained near the glass, and have plenty of light to mature their growth. ‘When they show flower, they should be brought down to the trellis, and treated exactly the same as Allamandas. They require to be grown vigorously in summer, and after flowering they should be gradually ripened by being kept moderately dry at the roots, and rested during winter, or till they require to be started to bring them into flower. A little before starting, the shoots should be pruned back to within a few buds of the wood of the previous year. When they break into growth, the plants may be re-potted if necessary, using good turfy loam, leaf- mould, and sharp sand, with comparatively small pots, and potting them very firm. A short time after re-potting the soil should be thoroughly soaked with tepid water, and the plants syringed daily to encourage a vigorous growth. The best for exhibition is the free-flowering B. glabra, but B. speetosa is also worthy of a place in a collection. 6 STOVE FLOWERING PLANTS. CLERODENDRON. This genus of plants comprises two groups, the one being seandant in habit, the other shrubby. As C. Balfourit is the most suitable species for exhibition, for which it has few rivals, our remarks will chiefly apply to it. Its free-flowering nature, and the ease and certainty with which it can be brought into flower at a given time, makes it invaluable for exhibition purposes. From ten to twelve weeks, according to its season of rest, is the usual period between starting and blooming. The main point to be observed in its culture is to secure strong, well-ripened growth, and then give it a fair amount of rest before starting it again. Being of a climbing habit, the shoots must be regulated during the growing season, and trained up strings or wires close to the glass. When the growth is complete, the shoots should be brought down and neatly trained over a suitable trellis. The greater the num- ber of well-ripened shoots, the more abundant will be the beau- tiful panicles of bloom. It thrives well in equal parts of loam and peat, with a little old mushroom-bed manure and charcoal. If the loam is heavy, a sprinkling of coarse sand will be beneficial. While the plants are growing freely, weak liquid manure should be given once a week. This plant should not be too often disturbed at the roots, a rich top-dressing being more beneficial when it has attained specimen size. CRINUM. Of this handsome tribe of bulbous plants, a good specimen is occasionally seen at an exhibition, and when of a large size and in perfect condition, it is an exceedingly attractive object. Among the best for this purpose is C. amabile, C. Moorei, and C. purpurascens. They thrive best when grown in large pots or tubs, in a compost of fibry loam and peat, with a good sprinking of half-inch bones and charcoal nodules intermixed. The drainage must be perfect ; and when the plants are well established, they will not require a shift for several years. A rich top-dressing annually at the time they are started to grow, and a liberal application of clear liquid manure while STOVE FLOWERING PLANTS. 7 growth is proceeding and the roots are active, will secure fine heads of the largest-sized flowers. To save the heavy heads of flowers while being conveyed to the show, they must be securely staked, and each flower supported with wads of cotton-wool carefully wrapped with tissue-paper. The plants require to be set in the full sunlight after they have done flowering, and the water gradually withheld, to thoroughly mature the bulbs, as upon their ripeness much of the success in their cultivation depends. They are mostly evergreens, and should not be dried off, like deciduous bulbs, but kept slowly moving through the winter in a temperature of 45° to 50°, and put into stove heat about two months before the date of the show. DIPLADENTA. All this genus of lovely stove climbers make excellent sub- jects for exhibition, and should be grown wherever a suitable house can be devoted to them. They are somewhat difficult to manage, and hence their value as exhibition specimens is fully recognised by all good judges of plants. When their requirements are understood and duly provided for, they can be grown to great perfection. One important point in their culture is to keep them clean and not over-water them. Although they require a moist atmosphere and high temperature, they will not thrive with a superabundance of water at the roots. Like all other climb- ing plants for exhibition, they must be trained close to the glass, and should have a corner in the stove where shading can almost be dispensed with, so as to ripen the growth thoroughly. In order to prevent the shoots intertwining, they should be trained singly to strings until they show flower, when they should be brought down and placed over a balloon trellis, on which they should be exhibited. When they cease flowering for the season, water should be gradually withheld, and the plants rested during the winter months. At the same time over-dryness at the root must be guarded against. Three of the most distinct for exhibition are D. amabilis, D. boliviensis, and D. Brearleyana. The soil best 8 STOVE FLOWERING PLANTS. suited for them is a mixture of turfy loam, fibry peat, sharp sand, and charcoal. The pots should be well drained, and the soil pressed firm about the roots. EUCHARIS. The lovely and sweet-scented Kucharis amazunica is, when well flowered, an invaluable plant for exhibition, as well as of great service for decorative purposes. The genus is a small one, and none of the species are equal to Amazonica for exhibi- tion. They are natives of New Grenada, and require a moist stove temperature to bring them to perfection. To form large specimens for exhibition, select the finest bulbs, wash them clean to see that they are perfectly sound, sprinkle them with silver sand, then plant them rather deeply in pots of a suitable size, placing the bulbs about three inches apart, and using a compost of rich fibrous loam well sprinkled with bone-meal and small bits of charcoal. The pots must be well drained, as the plants require abundance of water at the roots and copious syringing daily to grow them well. The leaves, after potting, should be supported by a few neat stakes till the roots get hold of the soil and are able to support the foliage. A stock of good plants being secured, they can be brought into flower at almost any season by judicious management. To bring them into flower at a given time, they should be encouraged to make a vigorous growth pre- viously, which should be thoroughly matured by keeping them dry and comparatively cool and well aired for about six weeks. They should be taken back to the stove about seven weeks before the show, and treated in the ordinary manner, with plenty of moisture in the air. After the pots are full of roots, the application of clear liquid manure twice a week is very beneficial. Should the flowers come too early for the show, the plants can be removed just as the flowers begin to open to a cooler house, and kept shaded for a week or two till they are wanted. Lach flower stem must be securely staked, and the flowers carefully protected in the usual way, for safety in transit to the exhibition. STOVE FLOWERING PLANTS. 9 FRANCISCEA, This is a beautiful genus of dwarf shrubs from Brazil, which are not so often met with in collections as they should be. They produce an abundance of pretty sweet-scented flowers at different times during the season, and are grown to perfection in 2 moderate stove temperature, J. calycina major and FF. confertiflora ave the best for exhibition. The plants must be kept closely pinched when young, to form a proper foundation for exhibition specimens; afterwards they are easily kept in shape by an annual pruning at the time they have done flowering. They should be re-potted every year in equal parts of fibry peat and loam, with about one-fourth of silver sand, making the whole firm in the pot. GARDENIA. This useful genus of free-flowering plants combines the qualities of beauty, fragrance, and profusion of flowers which have made it a popular favourite. Among the best for exhibition are G. florida intermedia, G. f. Fortuneana, and G. radicans major. The short-jointed shoots and shrubby nature of the plant makes it easily grown into a fine compact specimen. It thrives best in a mixture of equal parts sandy loam and peat, with silver sand and leaf-soil; but well-rotted manure and bone-meal should be added to the soil when re- potting specimen plants. It requires a moist and high tem- perature to make its growth, which should be gradually toned down as the plants come into flower. The Gardenia is very subject to the attack of insects, and should be syringed with soap-water to which has been added a gill of paraffin to the gallon. An excellent preventative for red spiders is to place over the plunging material a layer of stable manure, which should be kept moist. As soon as the buds are set, weak liquid manure with some soot dissolved in it should be given once a week, to increase the size of the flowers, and give a dark, healthy gloss to the leaves. 10 STOVE FLOWERING PLANTS, IXORA. Although these are considered rather difficult subjects to cultivate, they stand in the front rank of flowering plants for exhibition, for which purpose most of the species and varieties are well suited, especially I. coccinea superba, I. Colei, I Dufit, and I. javanica florabunda. They luxuriate in a high tem- perature, strong bottom-heat, moist atmosphere, and all the light possible, merely shading them from the strong sun at mid-day. While growing, they should be carefully attended to with water at the roots. When done flowering, they should recelve any pruning they require, and be rested, in a com- paratively dry state, in an intermediate house. They succeed best in fibry peat, a little leaf-mould, and plenty of silver sand, all well mixed, and potted moderately firm. After they have reached specimen size, they will thrive well for years without re-potting ; but they should be carefully supplied with weak liquid manure during the season of active growth. JASMINUM. There are many species of this excellent genus of trailing sweet-scented plants. Of the stove kinds, J. gracillimum and J. Sambac jflove pleno ave the best. The former is a profuse bloomer, and the shoots being very flexible, it can be grown as a specimen in any form to suit the taste of the cultivator. The balloon or the pyramid shape is best adapted for an exhi- bition specimen. They thrive well in a mixture of sandy loam and peat, with the addition of some old rotted manure. When the plants attain a large size, their luxuriance is very much promoted by applications of weak liquid manure during the growing period. MEDINILLA. Among the finest and most handsome of all stove plants is a well-grown and profusely-flowered specimen of AL. magnifica, a native of the Philippine Islands. It delights to make its growth in a high temperature and a moist atmosphere, shaded STOVE FLOWERING PLANTS. 11 from strong sunshine. When the growth is fully developed the plant should be exposed to all the light possible, to thoroughly ripen the wood, and then rest it in an inter- mediate house. From eight to ten weeks before the plant is required for exhibition, place it again in the stove. An open compost of turfy loam and peat, with a sprinkling of nodules of charcoal and half-inch bones, and plenty of silver sand to keep all open, grows it well. When the roots have filled the pot, and especially when the flowers are developing, a weekly application of clear liquid manure has a very beneficial effect. Cuttings strike readily in pure sand, with a strong bottom- heat, and covered with a bell-glass, The large and beautiful rosy-pink panicles of flowers remain in perfection for a con- siderable time ; but, in removing the plant to the exhibition, each panicle must be carefully supported by stakes and cotton- wool, as their weight is apt to damage the flowers if they are allowed to sway about or rub against anything. PANCRATIUM. This is a genus of bulbous, sweet-scented, white-flowering plants of some merit for exhibition. P. fragrans is a free- flowering plant, with large umbels of flowers of perfect purity, and long narrow segments radiating from the centre, which gives it a chaste and graceful appearance. It should be potted in strong fibrous loam, sand, and well-rotted hot-bed manure. It is generally cultivated under the same conditions as the Eucharis with great success. The plants, if placed in an intermediate house previous to flowering, with plenty of light and air to mature the growth, will continue much longer in flower than when confined to the stove. A few doses of liquid manure after the flower-scapes appear are productive of good results, but they should be stopped when the first flowers begin to open. When removing the plants to the show, the greatest care is necessary to prevent injury to the flowers, which should be enclosed in wadding without pressing against it, and the whole plant enclosed in tissue-paper and covered with stout canvas. Le STOVE FLOWERING PLANTS. POINSETTIA. This is one of the most striking and attractive winter deco- rative plants we possess. The typical variety P. pulcherrima and the white variety P. pulcherrima alba are both very showy plants, but the former is the most suitable for exhibi- tion. A two-year-old plant, if the wood is well matured, makes a good foundation for an exhibition specimen. The plants should be pruned to within two eyes of the old wood, and although they grow fairly well in a cold frame during the summer months, they are all the better of a little artificial warmth, especially during the night. When the buds are started, the old soil should be shaken away from the roots, and the plants potted amongst sandy loam and _ leaf-soil. They should be syringed twice a day, and very little water given at the roots until growth has fairly commenced. They should be kept near the glass, and plenty of light and air given, for the formation of strong, firm, short-jointed wood. From ten to twelve strong shoots are sufficient to form a fine specimen. Flowering may be forwarded or re- tarded by the time the plants are introduced to stove heat, three to four weeks only being necessary for the full develop- ment of the bracts after the plants are full grown. RONDELETIA. The Rondeletias are hard-wooded evergreen shrubs from the West Indies, producing freely their bright little trusses of flowers Among the best are 2’. cordata and R. speciosa major. The roots are small and fibry, and are liable to be injured by injudicious watering; but when the plants are grown into well-flowered specimens, they are very effective at the autumn shows when stove flowering plants are searce. On account of their straggling habit they require to be neatly trained into shape for exhibition; and in whatever form they are trained, the shoots should be fully exposed during the growing season, that they may be short-jointed and well matured. After flowering, the shoots should be cut back to within three joints of the previous year’s growth. When they are starting to «row is the best time to re-pot, using a mixture of rough STOVE FLOWERING PLANTS. 13 fibrous peat, light loam, and sharp sand, with a few bits of charcoal. Firm potting and careful watering are two essential conditions to ensure success. STEPHANOTIS. The fine stove-climber S. floribunda is indispensable to the exhibitor. Its pure white waxy flowers and thick leathery leaves fit it admirably for withstanding the changes of tem- perature which plants in exhibitions are subjected to. Under good cultivation it is a rampant grower, and should be trained in the same manner as other climbers, by running up strings under the glass around which the shoots will twine. They can then be easily brought down to the trellis when they show flowers. Although a plant of rapid growth and a gross feeder, it flowers best when rather confined at the roots; therefore large plants can be grown in comparatively small pots, and they will flower more freely if judiciously treated with liquid manure. The best time to re-pot is when they are starting into growth in spring, using good fibrous loam, leaf-mould, sand, and a little bone-meal. Careful water- ing is very essential, especially during the winter months, when the plant is resting. During the period of active growth, an occasional application of weak liquid manure will greatly benefit established plants which are getting pot-bound. The balloon form is the best mode of training for the Stepha- notis, which should be done some time before the exhibition, so that the leaves and young shoots may have time to assume a natural position. TABERN.EMONTANA. This is another sweet-scented useful stove evergreen shrub, somewhat resembling the Gardenia. T. coronaria flore pleno and 7. grandiflora are among the best for exhibition, the flowers of the former being pure white, and the latter of a yellow colour. They form by careful pruning and pinching fine compact bushes, which, when well flowered, stand high among exhibition plants. They thrive well under the same conditions of culture as recommended for the Gardenia, 14 STOVE FLOWERING PLANTS. THUNBERGIA. This is a genus of stove and greenhouse climbers, some, of which only are worthy of cultivation as exhibition specimens, T. laurifolia is a large-flowered species of a blue colour, which, from the length of time it continues to bloom, entitles it to be classed amongst exhibition plants. It makes a fine- looking plant when it is trained on a globular trellis with all its panicles of flower turned outwards. It requires a compost of fibrous loam and peat in equal parts, with a little sand and well-decayed manure. TOXICOPHL.ZA, Among stove-flowering plants 7, spectabilzs occupies a useful position, its white scented flowers being produced with great freedom. It is of a rather straggling habit, but with good treatment and carefully pinching and regulating the growth, it can be made to form a fine specimen for exhibition. It grows well under ordinary stove treatment, and should not be over-potted. When the pot is full of roots, weak liquid manure should be applied once or twice a week in the growing and flowering period. VINCA, The stove species of this genus, V. rosea, and V. 7. alba are excellent free-flowering plants, which, when well grown and full of flowers, are very attractive specimens for exhibition. ‘The stems and branches being very flexible, they can be trained into any form. An intermediate temperature suits them best, and they should be potted in light sandy loam with a sixth of well-decayed manure. JUDGING. In judging stove flowering plants, the chief points of merit are: (1) Profusion, quality, and freshness of the flowers; (2) large size, brilliancy of colour, and sweet odour when pre- sent ; and (3) size, health, vigour, and cleanness of the plant. STOVE FOLIAGE PLANTS. 15 SECTION IT. STOVE FOLIAGE PLANTS, ACALYPHA. A beautiful and easily grown genus of foliage plants, which form fine specimens for exhibition when carefully pinched and regulated in their growth. Among the best for this purpose are A. macrophylla and A. musaica. A compost of peat and loam in equal parts and a small portion of silver sand grows them well. They thrive best in a moist stove, where they should be kept near the glass, to obtain plenty of light to fully bring out the beautiful colours and markings of the leaves, ALOCASIA. This is a highly attractive family of plants, with bold, mas- sive foliage, often curiously shaped, and beautifully marked and coloured. They make grand exhibition specimens when well grown, and are very effective plants in any collection. Some of the best are A. macrorhiza variegata, A. metallica, A, Thibautiana, and A, Veitehti. To grow them with the greatest success, they require a high temperature, moist atmosphere, and abundance of water at the root while grow- ing. The pots should be about half-filled with drainage, and the compost be of rich, light turfy loam, peat, and chopped sphagnum, freely sprinkled with nodules of charcoal and sand- stone. Clear liquid manure is very beneficial when the roots have fully occupied the soil. ANTHURIUM. The large, handsome, and distinctly marked leaves of some of the Anthuriums are very conspicuous and telling objects in a collection of foliage plants, especially when grown and exhi- bited without a blemish. A. magnificum, A. Vettchi’, and 16 STOVE FOLIAGE PLANTS. A. Warocqueanum ave among the best and most distinct for exhibition. ‘They require the same culture and treatment as the Alocasias; giving them liberal supplies of clear liquid manure when they are growing freely, and keeping the air thoroughly saturated with moisture, so as to induce develop- ment in the foliage to its fullest extent. ARALIA. The Aralias are a very distinct and ornamental class of foliage plants, and the finer forms, such as A. Chabrieri, A. elegantissima, A. Regine, A. Veitchii, and A. Veitehii gra- cillima are in. great favour with exhibitors of plants for table decoration. They should be grown in light loam and peat, adding a little leaf-mould and sand, according to the texture of theloam. Vigorous young plants produce the finest foliage, and a succession of these should be kept up by cuttings struck in the usual manner, or by grafting the weaker on to the stronger growing kinds. The scion must be neatly and securely fitted to the stock, and they should be kept in a close moist atmosphere until union is complete. Perhaps the best method of securing well-furnished small plants is to notch the stem of a leading shoot at the base of the healthy and perfect foliage, tying a handful of moss over the notch. Keep con- stantly moist, and roots will soon push out, and when the moss is full of them, take off the shoot with the moss and roots intact, and pot them in a light, sharp compost. Keep closely shaded till the roots are through the soil, and then gradually expose to light and air. By this method well-furnished specimens are quickly formed, with perfect foliage from the surface of the pots, CALADIUM. This is an easily grown and useful class of exhibition plants, the luxuriant growth of their brightly and diversely coloured foliage, forming an excellent contrast with the greenery of other subjects. It is easy to make a selection for exhibition from among the numerous fine varieties now in cultivation, STOVE FOLIAGE PLANTS. 17 some of the oldest and best known making grand specimens in a short time under generous treatment. They thrive best in rough fibry loam and peat and silver sand, sprinkled with nodules of charcoal and bone-meal. Abundance of water, moist air, and shading from bright sunshine assist in the produc- tion of the finest leaves ; and when the pots become full of roots, liquid manure should be freely applied. When the leaves attain their full size, a drier and more airy atmosphere deepens the colours and makes the plant more hardy for exhi- bition. After the leaves ripen and die off in the autumn, the pots should be laid on their sides in an intermediate tempera- ture ; and special care must be taken to keep them at rest without risk of becoming ‘dust dry,” as the roots are then very liable to become “‘ mealy ” and worthless. They are easily propagated by division of the roots, and specimens of any size are readily formed by placing a sufficient number of strong roots or tubers in a pot of the desired size. CARLUDOVICA. An elegant and useful genus of foliage plants, with a resem- blance to palms in their habits and appearance. C. elegans and C. palmata make the best specimens. They grow freely in a moist stove, in a mixture of two parts peat and one of loam, with a liberal sprinkling of silver sand. A copious supply of liquid manure, when the plants are growing freely, increases the size of the leaves and the elegance of the plant for exhibition. CISSUS. In @. discolor we have one of the most beautiful of all the variegated-leaved plants in cultivation. It is a free growing stove climber, and makes a grand specimen for exhi- bition when brought out in its best condition and neatly trained over a suitable trellis. It thrives well in a compost of rough turfy peat and loam, with a little old mushroom-bed manure and sand, all well incorporated. When the pot is filled with roots, an application once a week of clear liquid B 18 STOVE FOLIAGE PLANTS. manure improves the size and brightness of the colour of the foliage. Being a deciduous plant, it should be kept rather dry during the winter, receiving just sutlicient water to keep the wood from shrivelling. It should be pruned, re-potted, and started in a moist stove about three months previous to the show, so as to have the foliage fresh and perfect. Vigorous young specimens produce the finest leaves; and as the plant is readily increased by cuttings, a succession of plants is easily maintained. CROTON. Almost the whole of the numerous varieties of variegated- leaved Crotons make first-rate exhibition plants, and most of them can be grown into fine specimens in a comparatively short time. They take a high place among foliage plants, and when well grown and their rich colours brought out to perfec- tion, they are objects of great attraction. They grow luxuri- antly in a high temperature, with a close, moist atmosphere ; and to obtain that, the ventilators require to be kept rather close, admitting air by the side ones only, and shading the roof to prevent the sun scorching the plants. In such a tem- perature the plants make the largest leaves and freest growth. When the plants have made their growth, the shading should be gradually dispensed with, and all the light and air possible admitted, while keeping up the high temperature, to colour the foliage to perfection. The plants should be thoroughly drenched with the syringe in the afternoon in summer, and in the forenoon in winter. A good syringing with soap-suds— two ounces of soft soap dissolved in a gallon of water is sufii- ciently strong—once a week is beneficial to keep off insects, as well as to give the leaves a clean, healthy appearance. They succeed best in a turfy loam of a medium texture, with a little bone-meal, nodules of charcoal and sandstone added according as the nature of the loam requires them. The pots must be well drained, and the plants must never be allowed to get dry at the root, which immediately affects the foliage and spoils it. Large specimens growing in pots full of their roots may have an occasional supply of weak liquid manure, STOVE FOLIAGE PLANTS. 19 but care must be taken not to give it too often or too rich, lest the foliage begin to lose colour. Notching and mossing the stem, as described for Aralias, is the best method for obtain- ing well-furnished small plants. CYANOPHYLLUM. When grown to perfection, C. magnificwm forms one of the grandest specimens for exhibition among all foliage plants. It thrives best in a high moist temperature, in a compost of turfy loam and peat, freely sprinkled with nodules of charcoal, sandstone, and half-inch bones. It must have perfect drainage, as it delights in abundance of water while growing, but it must not be allowed to stagnate about the roots. When the plant is growing freely, and the pot is well filled with roots, copious supplies of clear liquid manure should be given twice a week, which will grow the leaves to their largest dimensions. On strong well-grown plants they should reach a length of about 4 feet, and 2 feet wide. Special attention must be paid to this, and all other large-leaved fine foliage plants, to see that insects do not effect a lodgment on the under side of the leaves, where they quickly multiply and do much harm. Frequent application of the syringe, and the careful use of weak soap- suds in syringing, help much to keep the foliage free from insects, clean, and healthy. The Cyanophyllum should always be grown to a single stem, as the large and finely-marked leaves are displayed with the best effect on such plants. It strikes freely from cuttings of side-shoots taken off with a heel, inserted in sandy peat, and placed in a strong bottom-heat under a bell-glass. Young plants, when well managed, produce the finest leaves, and in a season will make splendid specimens for exhibition. DICHORIZANDRA. A pretty genus of stove plants, the flowers of which are often as attractive as the handsome and beautifully marked foliage. Among the best for exhibition as foliage plants are D. metallica picta, D. mosaica, and D. vittata. They thrive 20 STOVE FOLIAGE PLANTS. best in well-drained pots, in a mixture of equal portions of fibry loam, peat, and leaf-mould, with a sprinkling of silver sand. A moist stove temperature and copious supplies of water at the root, with daily syringings and shade from bright sunshine, grows them well. After the pots are well filled with roots, clear liquid manure may be given once a week; but it must not be overdone, to cause rank growth and loss of colour in the foliage. They require to have a thorough rest during winter, but they must be kept in the stove and water with- held, as they do not bear cold with impunity. DIEFFENBACHIA. A free-growing and very effective genus of fine foliage plants, which, under liberal treatment, produce fine exhibition speci- mens in a comparatively short time. Some of the finest for this purpose are D. Baraquiniana, D. Bausei, D, Jenmanii, and D. Weirti superba. Being natives of the tropical parts of South America, they require a high temperature and abundance of moisture to grow them well. They delight in rich open compost, of turfy loam and peat, with leaf-mould and sand freely intermixed, and a little dry cow-dung rubbed down amongst it. After the roots have reached the side of the pots, they are much benefited by frequent doses of clear liquid manure. DRACAINA. Like the Croton, the Draczna is indispensable to the exhibi- tor of foliage plants. Numerous varieties, with richly coloured leaves and graceful habit, have appeared during recent years, among which it is easy to select good kinds for exhibition. They thrive well in rich fibry loam, with a little peat, sand, and nodules of charcoal, and should be grown in an atmos- phere saturated with moisture and shaded from bright sun, to fully develop the leaves. With abundance of moisture in the air, no syringing should be necessary, and as a rule they are finer without it. Dracenas are extremely easy to pro- pagate, as every inch of the stem will root and grow, inserted STOVE FOLIAGE PLANTS. ?1 in sand in a strong bottom-heat, Tall plants, with bare stems and good heads, should be notched and mossed immediately below the leaves ; and as soon as the moss is full of roots, take off the tops and pot them with the moss intact, shading them in a warm moist place till they are well established, and they will soon make nice useful plants. FICUS. This genus provides many useful plants which are more or less ornamental, the most noteworthy being F. Parecelli. As an exhibition plant it is one of the most striking and attrac- tive. It has also a good habit, and can with very little trouble be grown into a symmetrical specimen. It requires an open compost of loam and peat, and an abundance of water while growing. It should be syringed often to prevent the attacks of red spider, which is its worst enemy. It should be placed near the glass, so that the ivory-white blotches may be well brought out on the leaves. The strongest shoots must be pinched, and the others tied into position where necessary, to form a symmetrical well-furnished pyramid. As it approaches the resting period, water should be gradually withheld, and the plants placed in an intermediate temperature. HIBISCUS. The only one of this genus suitable for cultivation as a fine foliage plant for exhibition is H. Cooper’. It forms a fine specimen, and in variety of colour it equals, if it does not excel, any other foliage plant in cultivation. In its young state it should be potted amongst fibry loam, peat, sand, and leaf- mould, but when it has attained to a large size, soil of the poorest description should be used in potting—starving it, as it were, into colour. It requires a strong heat and a position close to the glass to bring out the various rich colours in their greatest perfection. MARANTA. A genus of useful and easily cultivated plants; but being natives of moist warm regions, they require careful handling 32 STOVE FOLIAGE PLANTS. to withstand the dry cool atmosphere of exhibition tents, Among the best kinds are M. Lindenti and M. Veitchti. To grow good specimens and bring out the full beauty of their leaves, a high temperature and moist atmosphere are abso- lutely necessary. They thrive well in a mixture of fibry peat and loam, with a small proportion of silver sand and a sprink- ling of bone-meal, and should receive copious supplies of water at the roots when growing. Keep them rather dry in the stove to rest them during winter. MUSA. A genus of large-leaved noble-looking plants, most of which grow far too tall for ordinary stoves; but Jf Cavendishii, AM. coceinea, and AL, zebrina are well adapted for culture as exhibition plants. Their cultivation is simple and easy if they are kept clean, and a proper degree of heat and moisture main- tained. Under such conditions they soon rush up into large specimens, their handsome leaves producing quite a tropical appearance wherever they are placed. They should be potted in rough rich loam and sand, and when pot-bound they should be heavily top-dressed with rich manure. PANDANTS. A handsome genus of very graceful foliage plants, with leaves mostly of a green colour; but 7. javanicus variegatus and P.Veitehii combine elegance with a fine light variegation, and may be considered the best for exhibition. Young shoots of the purest and slenderest character, springing from the base of the stem, should be taken off with a heel, potted in sandy soil, and plunged in a propagating-house, where they will soon take root. They should be shifted on as they require it, but using small pots in comparison to the size of the plants, When they have reached specimen size, they should be potted in coarse sandy loam, with plenty of pieces of sandstone and charcoal. They should get all the light possible without injury from bright sunshine, to produce perfect variegation. When removing the plants to the exhibition, the leaves should STOVE FOLIAGE PLANTS. 23 be tied up to the centre, and carefully wrapped round with cloth, to prevent their spines doing injury to other plants placed near them during transit. PAULLINIA. The best of this genus for exhibition is P. thalietrifulia, the habit of which is scandant, but by close pinching it can be made to assume the bush form, when it very much resembles a specimen of some of the exotic ferns. It forms the best exhibition specimen, however, when it is trained on a balloon or pyramidal trellis. It grows freely when potted in light loamy soil and leaf-mould, kept in a moist warm atmosphere, syringed daily while growing, and supplied with weak liquid manure when the pot is filled with roots. PAVETTA. There are few species of decorative foliage plants that equal P. horlonivs in attractiveness, when its beautifully marked leaves are exhibited in their best condition. It is closely allied to Ixora, and succeeds well under similar treatment. The soil best suited for its growth is fibry peat and loam, with a few half-inch bones, and about one-fourth of silver sand. The plant should be repeatedly pinched while young, to make it branch out into a bushy specimen, which it does slowly. After growth is complete, it should be well exposed to the sun, to bring out the beauty of the markings on its leaves. PHILODENDRON. A large genus of tropical plants, of easy cultivation, and among which are some noble-looking specimens for the pur- poses of the exhibitor. Few foliage plants can compare with P. Andreanum for stately effect, and P. Lindenii and several others are nearly as striking and effective. Natives of the warmer parts of America, they luxuriate in a high moist atmosphere, with a rich open soil to grow in, and copious sup- plies of water both at the roots and overhead. When the pots are full of roots, liquid manure may be freely given with the 24 STOVE FOLIAGE PLANTS. best effect. They are easily propagated by cuttings of the strong stems, which quickly root and form fine plants. RHOPALA. An elegant genus of fine foliage plants, some of which are very useful for decorative purposes, as well as furnishing beautiful specimen plants for the exhibitor. Among the finest are I. corcovadensis, R. elegantissima, and R. Verveeneana, which all grow best in a stove temperature, although they also thrive well in a warm greenhouse. A compost of fibry loam and peat, with charcoal nodules and sand, grows them well. They delight in moisture while making growth, but should be gra- dually exposed to air and light, and, placed in an intermediate temperature, they will retain their foliage in a perfect condi- tion through the whole year, and are thus nearly always avail- able. They strike freely from cuttings placed under a bell- glass in a strong bottom-heat, or the tops may be notched and mossed, when good-sized plants are secured at once. SANCHEZIA. The only species of this genus suitable for exhibition as a foliage plant is S. nolalis vartegata. This is a widely cultivated plant, which grows freely, and makes a handsome specimen when its leaves are fully developed and their variegation well brought out. It should be potted in equal parts of fibry loam and peat, with some small bits of charcoal and silver sand. It must be grown near the glass and shaded only to prevent scorching, and have the flowers nipped out as they appear. The leaves should be frequently sponged to keep them clear of aphides, which prove harmful to them when in a young state. SONERILA. This is a genus of beautiful dwarf-growing plants, as much admired for the beauty of their flowers as for their foliage. The best for their foliage are S. margaritacea Hendersonti, S. m. marmorata, and 8. m. superba, which all possess a branching, STOVE FOLIAGE PLANTS. 35 compact habit, and form very neat specimens. They bloom freely, and the flowers look well; but, like all plants when grown specially for their foliage, the flower-buds should be nipped out as they appear. A compost of two parts fibrous peat and one of chopped sphagnum, sand, and charcoal nodules grows them well, They should receive plenty of water and shade in summer, but be well exposed to the sun and kept slightly dry when resting. SPH-EROGYNE. The plants belonging to this genus are highly ornamental, and among the best for exhibition are 8. ¢mpertalix and S. lati- Jolia. Under proper treatment their leaves grow to a large size, and form noble-looking plants; but to secure perfect foliage the plants must be grown in a moist warm temperature and well shaded. They very much resemble the Cyanophyllum, and thrive well under the same treatment. TERMINALIA, The only species of this genus suitable as a foliage plant for exhibition is 7. elegans. Its persistent habit of growing with a single stem makes it rather difficult to work into a large specimen. It thrives well in a mixture of loam and peat with about a fourth of silver sand. To produce a large specimen, the plant should be cut down while young, and repeated if necessary to secure fowr shoots, which should be bent outwards and staked, to keep them clear of each other. A native of Madagascar, it luxuriates in a warm moist atmosphere, with plenty of water when growing, but should be kept moderately dry in winter. It is much benefited by a judicious application of liquid manure, like many other foliage plants; but care must be exercised in its use, as leaves with rich delicate colours are liable to be spoilt if the plants receive too much feeding. THEOPHRASTA, A genus of stately foliaged plants, with large coriaceous leaves of great substance and beauty. Of those in cultivation, 26 STOVE FOLIAGE PLANTS. T. imperialis and T. macrophylla form grand specimens for exhibition. Natives of Brazil, they luxuriate in a strong moist heat while making their growth, with a copious supply of water at the root and overhead. When growth is well ripened, they stand in an intermediate temperature a long time in fine condition. They thrive well in a mixture of fibry loam and peat, with a good sprinkling of half-inch bones and sand; and while the plant is growing and the roots active, frequent doses of clear liquid manure encourage the development of the largest-sized leaves. TILLANDSIA. An extensive genus of beautiful stove plants, most of which are epiphytal, although under proper treatment they thrive well in pots and baskets. Among those cultivated as foliage plants, most of which also produce lovely flowers, the best known are T. musaica, T. splendens, and T. zebrina. They are an easily grown class; but while they are making growth they thrive best in a high moist temperature, with a copious supply of water at the root and heavy syringing overhead daily. The compost they delight in is a fibry loam and peat, with a sprinkling of half-inch bones, and nodules of charcoal and sandstone, in well-drained pots. They should be kept rather dry while at rest during the dormant season. JUDGING. In this class above most others, large size is of small value, unless accompanied by all-round excellence. Under-sized foliage plants are also of little value, however well done they may be. A useful medium size, according to the nature of the plant, with every part fully developed, is always preferable. The properties of foliage plants are: (1.) Condition, habit, symmetry, and size of the specimen; (2.) the foliage healthy, clean, and perfect; and (3.) the colour and variegation of the leaves should be clear, vivid, and in good contrast. GREENHOUSE FLOWERING PLANTS. Io —~T SECTION III. GREENHOUSE FLOWERING PLANTS. ACACTA. A numerous genus of free-flowering and highly ornamental plants, chiefly natives of the temperate regions of Australia, and thriving well in a cool greenhouse. A. armata, A. Drum- mondi, and A, Riceana ave among the finest species for exhi- bition. They grow well in equal parts of light turfy loam and peat, with plenty of silver sand and a sprinkling of sandstone and charcoal nodules. The plants should be cut back after flowering, and with the aid of a few degrees more heat, and a thorough syringing overhead twice daily, they will soon break into growth, when they should be re-potted. Give as small shifts as possible, and make the soil quite firm in the pot, so as to induce sturdy and more floriferous growth. The drainage must be ample, so as to allow copious supplies of water to be given during growth, and when the roots have fully occupied the soil a few doses of liquid manure are very beneficial, They are apt to make rampant growth under liberal treatment, and the strongest shoots should be regularly pinched to form a good bushy specimen. Such straggling kinds as A. Riceana may have the shoots run up the roof of the greenhouse on strings till the flowers appear, when they can be neatly trained over a suitable trellis for exhibition. Acacias are very hardy greenhouse plants, and after they have made their growth and set their flower-buds, they may be placed out of doors, along with other greenhouse plants, to ripen their wood, and they will flower the better for it next season. They must be taken back to the greenhouse before any danger from frost arises. ACROPHYLLUM. A large specimen of 4. venoswm, when full of its beauti- ful flower-spikes, has a charming effect among other plants 3S GREENHOUSE FLOWERING PLANTS. in a collection. Its pinkish-white flowers are so very dis- tinct from all others that it is always a welcome subject at summer shows. It should be potted in the beginning of March amongst fibrous peat and about one-fourth of sharp sand, and kept in a cool airy place in the greenhouse. Being of a compact habit, it requires very little tying or trimming, but it must be kept clean by syringing daily during the summer. It should be well supplied with water at all times, and a little liquid manure, given two or three times before flowering, tends to develop the flower-spikes to their fullest extent and beauty. AGAPANTHUS. The blue African lily is a plant that suits itself to almost any treatment, and being of a hardy nature and tenacious of life, its culture is often neglected. It is not a first-class exhibition plant, but its graceful arching leaves, independent of its fine flowers, make it a good associate amongst stiffer- growing plants. Two of the best varieties are A. wmbellatus flore pleno and A. umbellatus maximus. They should be potted amongst rough loam, sand, and decomposed manure, and receive an abundance of both clear water and liquid manure in summer, but should be kept drier in the winter season, APILTELENIS. An old-fashioned genus of greenhouse plants,-of a rather straggling habit of growth, but which by skilful treatment make very beautiful and attractive exhibition specimens. Among the finest for that purpose are A. macrantha pur- purea, A. (Phaenocoma) prolifera Barnesi’, and A. purpurea grandiflora, Young plants require to be kept well pinched, to form a good foundation for a large well-furnished specimen. The plants grow well in good fibrous peat and silver sand, with plenty of nodules of charcoal and sandstone sprinkled through it; draining the pots thoroughly, and potting very firm, As the plants grow, the shoots should be neatly trained in the desired form, using as few stakes as possible, and neatly GREENHOUSE FLOWERING PLANTS, 29 “threading” the intermediate shoots to keep them into their position. The attractive silvery appearance of their stems and leaves, and the bright rosy-purple of their beautiful “everlasting” flowers, make the Aphelexis always very inte- resting objects. AZALEA. With the exception, perhaps, of the Erica, there is no tribe of greenhouse flowering plants so useful as the Azalea to the exhibitor. The numerous first-class varieties of A. indica which are now in cultivation give the exhibitor a wide choice in selecting the best for his purpose. In flower they make a brilliant and highly attractive display, and are a prominent feature of flower-shows in spring and early summer. A cool greenhouse is their best winter quarters ; and when they are wanted for early spring shows, they must be introduced to heat in due time to get them into flower. They bear mild forcing remarkably well, and from six to eight weeks, accord- ing to the variety, is generally sufficient to get them into full bloom. A temperature of 55° at night, rising 5° to 10° in the daytime, is better than harder forcing. Keep plenty of moisture in the atmosphere, and shade from bright sunshine. When the flowers begin to expand, reduce both heat and moisture, and gradually harden them off, so as to enable them to stand exposure at the exhibition. They should be re-potted when needful soon after flowering; using fibry peat, and a little turfy loam and leaf-mould, with a good sprinkling of silver sand and charcoal nodules. Place them in a moist atmosphere, with a heat of 60° to 65° at night, and shade from sunshine till they have made their growth and set their buds, when they should be gradually hardened off, and may be set out of doors in autumn to thoroughly ripen; moving them into winter quarters before there is any danger of frost. BORONIA. The Boronias are a useful and elegant genus of greenhouse plants, and form handsome specimens when properly treated. 30 GREENHOUSE FLOWERING PLANTS, Among the best for exhibition are B. Drummonddi, B. elatior, B. hetrophylla, and B. pinnata. They thrive best in fibry peat and loam, with a good sprinkling of sand, and small bits of sandstone and charcoal freely mixed. The pots should be well drained, and the soil made very firm. Young plants should be closely pinched, so as to form good bushy specimens, BOUVARDIA. There are many species aud varieties of these useful green- house plants in cultivation. Bouvardias are not often used as exhibition plants, but when they are well cultivated and trained, they make very handsome and attractive specimens. A few of the best varieties for this purpose are Alfred Neuner, Brilliant, Dazzler, Hogarth, President Garfield; and Vreelandi. They should be potted in a compost of two parts of sandy loam, one of peat, and one of sand and de- composed manure well dried and rubbed down. The best way to grow and train them into specimens is to pinch them well while the plants are young, and keep them near the glass to secure strong, sturdy growth. The shoots should be spread out like those of a trained Erica, and if the flower- trusses stand erect without stakes, so much the better. When the plants begin to flower, they are greatly benefited by liquid manure from sheep-droppings and soot. CAMELLIA. For many years the Camellia was the favourite winter and spring flower, and although it has had to give place to a cer- tain extent to the improved forms of the Chrysanthemum, still as a greenhouse flowering plant it has few rivals. The follow- ing are twelve of the best: Alba plena, Augustine superba, Bella portuensis, C. M. Hovey, Countess of Orkney, Fimbriata, Imbricata, Jubilee, Lavinia Maggi, Mathotiana, Targioni, and Valtevaredo. Their cultivation is similar to that of the Azalea, except that the major part of the compost should be turfy loam, with a little peat, rotted manure, and bone-meal added. The potting, when necessary, should be done after GREENHOUSE FLOWERING PLANTS. 31 flowering, and before much growth is made; but oftener a top-dressing of rich soil is all that is required, especially with large plants. A vinery, if not too much shaded, is an excellent house for them to grow in; but as soon as the growth is finished the plants should be hardened off, to prepare them for standing in a sheltered place outside. Success for the next year depends upon judicious watering and perfect ripen- ing of the wood during summer andautumn. The buds should be thinned to one or two on each shoot, and when they begin to swell, the plants should be watered with liquid manure until the flowers are fully expanded. CLIANTHUS. This is a genus of quick-growing plants, which, although scandant in habit, if well pinched and the shoots regulated, are capable of being grown into neat bushes suitable for exhibition. Two of the best species for the purpose are C Dampieri and C. puniceum magnificum. The soil best suited for their growth isa rich fibrous loam and peat in equal parts, with a little sand and leaf-mould added. When the flowers appear, a few doses of clear liquid manure greatly improves the quality of the blooms. CORREA. A genus of neat-growing, fine showy plants, of easy cul- ture. Two of the best for exhibition are C. cardinalis and C. magnifica, the former scarlet, and the latter of a white colour. The soil best suited for them is half light loam, the other half consisting of peat, leaf-mould, and sand. The plants should be slightly pruned after flowering, and as soon as they have started to grow, they should be potted, and after their growth is made, treated the same as Camellia. CRASSULA. This genus, known also as Kalosanthes, belongs to a succt- lent class of plants, with very pretty flowers, mostly of a scarlet colour, which, when freely produced, have a showy and 32 GREENHOUSE FLOWERING PLANTS. charming effect. C. coccinea and C. jasminea are very suitable subjects for exhibition, especially as amateurs’ plants. They should be potted amongst sandy loam in a lumpy state, with the addition of broken pots and bits of old mortar and chayr- coal. They do not require much water, especially in winter, but a little liquid manure when they are in full growth gives them a vigorous and healthy appearance, and much improves the flowers. They should be trained with the lower branches in a horizontal position, and the others staked thinly and equally over the whole of the half-globe shape. The pinching of the tops to form side-shoots should be all done at once, so that the heads of flowers which appear the following year may be all developed at the same time. CYTISUS. This is a rather extensive genus, the greenhouse species of which are mostly yellow-flowered compact-growing shrubs, and are very useful decorative plants. The following are among the best for exhibition specimens:—C. cancariensis, C. Everestianus, C. filipes, and C. racemosus. They all grow freely from cuttings and seeds, but C. filipes is shown to best advantage when grafted on a stronger-growing species, on a stem about three feet high, where, from its graceful drooping habit, it forms a very beautiful specimen. They grow freely in a compost of fibry loam and peat, with a free sprinkling of sand and charcoal. After they have flowered, they should be pruned into shape and repotted. When carefully handled, they form nice pyramidal specimens ; and when the roots fill the pots, they should be liberally supplied with water and occasional doses of liquid manure till growth is finished. They may then be set out of doors to ripen, and be wintered in a cool house, introducing them into a warmer house if necessary to get them into flower for the show, DAPHNE. This is a genus of evergreen shrubs, chiefly noted for the sweet perfume of their flowers, and being of a good habit, GREENHOUSE FLOWERING PLANTS. 33 make, when well grown, fine exhibition plants. Among the best greenhouse kinds are D. elegantissima and D. indica rubra. They grow freely in a compost of peat, leaf-mould, and sand, and require frequent pinching when young, to get them into a nice bushy form. Good drainage and an ample supply of water while growing are necessary. To secure a profusion of bloom, the main point to be observed is the thorough ripen- ing of the wood by full exposure to light and air, and keeping the plants rather dry. DRACOPHYLLUM. The most valuable species of this genus is D. gracile. It makes a fine specimen, either trained on a trellis or pinched and neatly staked out in bush form, and should be in every collection for exhibition. It grows best in rough fibrous peat and one-fifth of silver sand. If trained on a trellis, the flowering shoots should be carefully brought to the outside before the flowers begin to open. EPACRIS. This is an elegant genus of plants, which is generally associated with the Erica, and although natives of different countries, they thrive under almost the same conditions. A few excellent kinds for exhibition are Hyacinthiflora can- didissima, H. fulgens, Miniata splendens, Rubra superba, Sunset, and The Bride. The soil best suited for their cul- ture is rough fibrous peat with a liberal addition of silver sand, After the plants have flowered, the strong-growing kinds should be cut down to within two or three eyes of the old wood, the weaker ones being left a little longer. They should be shifted just after they have started to grow, making the soil very firm, and kept in a close frame till the roots are established in the new soil, after which more air should be given, and the sashes be ultimately removed altogether. It is of much importance in growing the Epacris and Erica that Vicissitudes of dryness and heat be guarded against, and there- fore they should never be set in an exposed position, where c 34 GREENHOUSE FLOWERING PLANTS. they might suffer from heat and drought. The best mode of training is that which exhibits the greatest quantity of flower with the least degree of stiffness or formality. The shoots should be arching gracefully to the outside, and kept in position by neat stakes and green-coloured threads, which should be removed, if possible, when the plants are exhibited. ERICA. As flowering specimens, the Ericas or Cape Heaths may he considered the standard greenhouse plants for exhibition, and when staged in first-class condition, are universally admired, and stand high in cultural merit. To manage them well, they require a house for themselves, or they may be associated with such hard-wooded greenhouse plants as thrive under somewhat similar conditions. They are a very durable race of plants, and by careful management and strict attention to their re- quirements they can be most successfully grown and exhibited for many years. There are many species and varieties of Erica suitable for exhibition, among which the following hold a prominent place:—£. Aitoniana Turnbullii, E. aristata wajor, E. Carendishii, E. elegans glauca, E. Marnochiana, E. Massonil, E. vetorta major, E. tricolor Wilsont, E. ventricosa, E. v. splendens, E, vestita, and E, VWietsarie. The soil they thrive in is good fibry brown peat, torn up into small frag- ments and the finer particles left out; to this should be added a liberal amount of silver sand, and nodules of charcoal and sandstone, varying the quantity according to the quality of the peat. Drain the pots carefully, and press the soil as firm as possible with the potting-stick, finishing off with a thin layer of fine soil. A judicious and liberal amount of water must be given at the roots at all times, but a more copious supply is necessary during the season of active growth. If the ball of soil once becomes dry, the small fibry rootlets will suffer to such an extent as to cripple the energies of the whole plant, and, if it does not die off in consequence, it will take years to recover itself. The best time to re-pot is when the plants are starting into growth. Large shifts must be GREENHOUSE FLOWERING PLANTS. 35 avoided ; from a six to an eight-inch pot being enough at one time, and possibly for two or three years, all depending upon the progress and health of the plants. Only enough artificial heat should be applied to the house during winter as will keep out frost and dispel damp; and when heat is employed for the latter purpose, it should be applied during the day and in fine weather, with a little air passing through the ventilators. Mildew is the great enemy of those plants, and when it appears, it must be immediately attended to.
