WE are again called upon to present to the public the 6th edition of this popular work on the Culture of Flowers—a taste that :s now widely disseminating itself; in fact, a know- ledge of which is requisite before a refined education is com- pleted. We boldly and fearlessly say that no country has made such rapid advancement in the art and science of Horti- eulture in so short a period as the United States. Wherever the taste prevails, it diffuses a peace and harmony among its participants without either symbol’ or mystery. In this edition, a feast of new materials has been served up; entire lists have been cancelled and replaced with those of newer and finer forms and habits; extraneous matter and plants of indifferent character are dropped. The great and successful adaptation of Hot water to Horticultural purposes is explicitly described, and to those who wish to examine the results, we say “Come and see.” . ° e Myrtles and oleanders, : : . . .

UN LAYING OUT A FLOWER-GARDEN. ‘frm Klower-Garden is chiefly devoted to the cultivation of enowy towering plants, shrubs, and trees, either natives of nis country or those of a foreign clime ; it is a refined ap- pendage to a country seat, “suburban” villa, or city resi- dence ; every age has had its principles of taste, and every country its svstem of gardening. Our limits do not permit us to enter nunutely into the details of any of these sys- tems ; but a few mts may not be out of place to those whose design is the laying out or improvement of the garden. The Italian style 1s characterized by broad terraces and pa- ralled walks, having the delightful shade and agreeable fra- grance of the orange aud the myrtle. Terraces may be a/- vantageously adopted to surmount steep declivities ; and, if judiciously laid out, would convert a sterile bank into a beautiful promenade, or choice flower-garden. The French partially adopt the above system, interspers- ing it with parterres and figures of statuary work of every character and description. When such is well designed and neatly executed, it has a lively and interesting effect; but now the refined taste says these vagaries are too fantastic, and entirely out of place. A late writer says of Dutch gar- dening, that it “is rectangular formality :’ they take great pride in trimming their trees of yew, holly, and ae ever * (17 is ON LAYING OUT A FLOWER-GALDEN. greens, into every variety of form, such as mops, moons, hal berds, chairs, &e. In such a system it is indispensable ta order that the compartments correspond in formality, nothing being more offensive to the eye than incongruous mixtures of character. The beauty of English gardening consists in an artful imitation of nature, and is consequently much dependent on aspect and locality. It is a desideratum, where wood and water can be combined with the flower-garden, and the prac- tical eye can dispose of an object to advantage by interspers- ing shrubbery and walks, that the combined cbjects form au agreeable whole. They are not to be disposed with a view to their appearance in a picture, but to the use and enjoy: ment of them in real life. We will now endeavour to give an explicit exposition of a system adapted to our variable climate of extreme heat and excessive cold. Where choice of aspects can be obtained, preference should be given to a south-east or east; but if not, south or south-west, and, if possible, sheltered by ris- ing ground or full-grown woods from the north-west and north. But to lay down directions for a flower-garden is not a little difficult, seeing that there cannot be any given area or any description of local cireumstances applicable to all situations. A good soil is the sure foundation on which to rear the grand floral superstructure, and the most genial is a sandy loam: I mean by sandy loam a soil which contains from one-sixth to one-tenth of sand; and if ona gravelly or sandy bottom, so much the better. Where the general sur- face is gently undulating, it will greatly add to the beauty of arrangement ; if access to a spring can be obtained, it will prove a desideratum in completing the whole: it can pe available for a fish-pond or an aquarium, or can be convert- ed into a swamp for the cultivation of many of our most beautiful and interesting native plants, such as Habanaria, Lilium, Sarracenia, Dionea, &c., and on the margin of which (Gf partially shaded) can be planted the beautiful varieties of Azaleas, and the splendid flowering Rhododendron, which by the by, are almost entirely neglected in all our floral deco rations. With many, the arrangement of a flower-garder is rather a matter for the exercise of fancy, than one calling for the application of refined taste: true, it may be saiu there is no mathematical law to guide the designer, so tt a ON LAYING OUT A FLOWER-GARDEN. 19 if he avoid incongruity of arrangement the end is accom. plished. But, in commencing these operations, a design should be kept in view that will tend to expand, improve, and beautify the situation ; not, as we too frequently sce it, the parterre and borders with narrow walks up to the very household entrance: such is decidedly bad taste, unless com- pelled for want of room. For perspicuity, admit that the area to be enclosed should be from one to three acres, a cir- cumambient walk should be traced at some distance within the fence, by which the whole is enclosed ; the inferior walks should partly circumscribe and intersect the general surface in.an easy, serpentine, and sweeping manner, and at such distances as would allow an agreeable view of the flowers when walking for exercise. Walks may be in breadth from three to twenty feet, although from four to ten feet is gene- rally adopted; and, to have these dry and permanent, those that are to be much used should have six to eight inches of the bottom soil dug out in a concave manner, and in the centre of the concave dig out a trench of about nine inches square, to form a drain, which may be made with brick or filled with rough stone, and the concave may be filled with refuse of buildings or broken stone within three inches of the desired height, which should be covered with gravel, and then firmly rolled with a heavy roller. Where the gravel cannot be obtained, sand may be used, mixed with a few small stones to bind it, but such needs very repeated rolling. Walks, such as described, when completely finished, will last for ages; but many will not be disposed to go to such ex- pense ; to those we say use tanner’s bark, which is very cheap, and accessible to all. The outer margin of the gar- den should be planted with the largest trees and shrubs; the interior arrangement may be in detached groups of shrub- bery and parterres. In order that the whole should not partake of a uniform and graduated character, it should be broken and diversified by single trees planted in the turf, or arising in scattered groups from a base of shrubs. In some secluded spot, rock-work or a fountain, or both, may be erected ; the foundation of the former should consist of mounds of earth, which will answer the purpose of more solid erections, and will make the stones go farther: rocks of the same kind and colour should be placed together, and the greatest possible variety of character, size, and form 29 ON LAYING OUT A FLOWER-GARDEN should be studied, the whole showing an evident and well defined connexion. ‘These erections generally are stiff, arti- ficial, disjointed masses, and often decorated with plants having no affinity to their arid location. The undertaking, when well completed, will present a field of varied and iw- teresting study, and more than compensate for the labour and expense bestowed upon it. If it is desired that the flower- garden should be a botanical study, there should be some botanical arrangement adopted. The Linnean system is the most easily acquired. A small compartment, laid out in beds, might contain plants of ari the twenty-four classes, and a few of all the hardy orders, which do not exceed one hundred. Or, to have their natu- rai characters more assimilated, the Juss/ewean system could pe carried into effect by laying down a grass-plat to any extent above one quarter of an acre, and cut therein small ugures to contain the natural families, which, of hardy plants, we do not suppose would exceed one hundred and fifty. The difficulties of this arrangement are, that many of the cha- racters are imperfectly known, even to the most. scientific. (Sce Professor Lindley’s Introduction to Botany.) All the large divisions should be intersected by small alleys, or paths, about one and a half or two feet wide. When there is not’ a green-house attached to the flower-garden, there should be, at least, a few sashes of framing, or a forcing pit, to bring forward early annuals, &c., for early blooming. These should be situate in some spot detached from the garden by a fence of Roses, trained to trellises. Chinese Arbor vite, Privet, or even Maclura, make excellent fences, and, when properly trimmed, are very ornamental: they require to be neatly and carefully clipped with shears every September. In the Southern States, Noisette, Bourbon, and China Roses, with a profusion of Sweetbriar, would make the most beauti- ful of all fences, and could be very easily obtained : a fence three hundred feet long would only cost abot one hundred and twenty dollars. Frames for forcing should be made of plank two inches thick, and well put together; the sash should be from five to seven feet long, and from three to four feet wide, and filled with six by eight glass. In the framing- ground should be kept the various soils required for plants, and also variou. characters of manure at all times ready far use, the whole in regular heaps, and kept free from t Jan. | OF FRAMING, ETC. 2 weeds.-—Haviuy given these brief outlines of a flower-garden, we now proceed to give monthly directions for planting ant. keeping the same in order. JANUARY. Ir the covering of the beds of choice bulbs, herbaceous plants, or tender shrubs, has been neglected last month, let it be done forthwith. The season is now precarious, and delays are dangerous. For particular directions, see Decem- ber. Any bulbous roots that have been kept out of the ground, should be planted immediately, according to direc- tions in October. Some writers have recommended keeping some of the bulbs until this month, in order to have a con- tinued succession. Experience will prove the inefficiency of the plan, and will satisfactorily show that the difference is almost imperceptible, while the flowers are very inferior, and much degenerated ; and, in place of having “a long-con- tinued succession of bloom,” there appear, along with your finest specimens, very imperfect flowers, caleulated to discou- rage the admirers of these “ gaudy” decoratives of our flower- gardens. Whereas, every art employed should be to the advancement and perfection of nature. OF FRAMING, ETC. The plants and roots that are in frames should be protect ed with straw, mats, and boards, and the frame surroundec with litter, or leaves, or, what is more advisable, banked with turf—the former being a harbour for mice and other vermin. For full directions, see December. Under this head, the plants, such as Auriculas, Polyanthus, Daisies, Carnations, Pinks, Pentstemons, Campanula pyramidalis, Double rocket, Double stock, or Stockgillys, Double Wall- flower, Anemone, Ranunculus, &e., as previously enumerated as frame plants, will require very little water, and be sura to give none while they are in a frozen state. If snow 9% 22 OF PRUNING. [Jan should cover them, the plants will keep in a fine state under it; so never remove snow from covering cold frames, even suppose it should lie for weeks—nature will operate here herself. But when framing cannot be obtained, they will, in this latitude, keep tolerably, if gently covered with leaves or litter, using means to secure them from being blown over the garden. OF PRUNING. It is not advisable to carry on a general system of pruning mm this month, in whatever state the weather may be. The severest frosts, generally, are yet to come, and too frequently what is done now in this operation has to be repeated in the spring, causing, at that time, work to a disadvantage ; because, if pruning, when done just now, is accomplished judiciously, whatever more is requisite to be done in the spring on the same bush will be injudicious. Hence, it is far preferable to delay it till the frost is nearly over, when all can be done to advantage. There are, undoubtedly, hardy trees and some shrubs, that may be pruned and thinned out at any time from the first of November to the first of March: such as Crataegus, Sorbus, Spirea, and even Althea, in the Middle States; (the Double white Althea is very tender, and requires to be covered.) The tying together the loose branches of Juniper, Cedar, and Arbor vite should be particularly attended to, as heavy snow frequently destroys the shape of those handsome shrubs by breaking down the branches, &c.—When the snow is heavy, the precaution of shaking it off should be resorted to. In many seasons, the beginning of this month is open, and admits of the operation of digging in open quarters, which if not done, as advised last month, ought not to be delayed. The fruits of it will appear in the mellowed state of your soil in spring. If there is any spare time, tallies, straight sticks, or stakes, may be prepared for summer use. Tie them up in neat bundles, which will be of great service during the hurried period of the year. An opportunity of this kind should always be laid hold of ; the beneficial results will, in season, be displayed. Feb } OF PRONING, EY. 23 FEBRUARY. WHEN the borders and various compartments were dug in the autumn, and compost, or a thin coating of well-decom posed manure given, the advantage will now, in part, be ex perienced. If the weather is open about the end of the month, the pruning should be done with the utmost des. patch, that all may be prepared for a general dressing next month, and let nothing be delayed which can now properly be accomplished, under the idea that there is time enough. OF PRUNING, ETC. Generally, about the end of the month, the very severe frosts are over, and when none need be apprehended that would materially injure hardy shrubs, they may be freely pruned, and the points cut of such shoots as may have been damaged by the winter. Most of shrubs require nothing more than to be thinned of straggling, irregular, and injured branches, or of suckers, that rise round the root, observing that they do not intermingle with each other. Never trim them up in a formal manner; regular shearing of shrubs, and topiary work, have been expelled as unworthy a taste the least improved by reflections on beauty, simplicity, and grandeur of nature. In fact, the pruning of deciduous, hardy shrubs should be done in such a manner as not to be observable when the plants are covered with verdure. It may frequently be ob- served in flower-gardens, that roses and shrubs of every de- scription are indiscriminately cut with the shears, the Amdr- phas, Viburnums, and Althéas sharing the same fate. Robinias, Coliteas, Cytisus, Rhis, Gentstas, with several of the Viburnums, and many others, bear their flowers on the wood of last year, and, when thus sheared, afford no gratification in flowering. And those shrubs that thus flower on the shoots of last year are perhaps worse to keep in regu- lar order than those to which the knife can be freely applied ; but good management, while young, will insure handsome, free, flowering plauts. 24 OF PRUNING, ETC. [ feb Climbing shrubs, and others that are trained against out- buildings, walls, or such as are sheltered thereby, and not now in danger of suffering by frost, may be pruned and dressed. These should be neatly trimmed, and the branches moderately thinned out, tying in all the shoots straight and regular. Avoid, at all times, the crossing of any shoots. There is not a shrub in the garden that agrees so well with close-cutting as the A/théa, and all its varieties. These can be made either bushes or trees, and kept at any desired height. Where the wood of last year is cut to about two or three inches from the wood of the former year, the young shoots of the coming season will produce the largest and fincst flowers, and likewise more profusely. When they have attained the desired height, let them be kept in the most natural and handsome shape that the taste of the operator can suggest. ‘I'hey will bear cutting to any degree. Honeysuckles, of every description, may, with all free- dom, be trimmed, providing the frost is not very severe. These are very frequently allowed to become too crowded with wood, and then superficially sheared or cut. The flowers would be much finer, and the bush handsomer, if they were regularly thinned out, divesting them of all naked and superfluous shoots. Of those that remain, shorten the shoots of last year. Where any of the honeysuckle kind has be- come naked at the bottom, and flowering only at the top of the trellis, or extremities of the shoots, one-half of the bush should be cut to within four inches of the ground. It will throw out plenty of fine, young wood, which give room for, and train them straight, and to the full extent, during sum mer. These shoots will flower protusely the following sea son, and in like manner, when thought proper, the other half can be cut. Roses of the hardy kinds (termed garden roses) that were not attended to in November, should, if the weather permit, be dressed and pruned forthwith. In small gardens, where these are generally attached to the walls and fences, neatness should be a very particular object. If any of such bushes have got strong and irregular, the most proper method to bring them to order will be to cut down each alternate shoot of the bush to within a few inches of the surface, thereby renovating it, and, in part, preserving the flowers. Those that are cut down will put out several luxuriant shoots Feb. | OF PLANTING SHRUBS, ETC. 25 which must be regularly tacked in, spreading them in a fan shape. These, in another year, will flower well, when the others may go through the same operation. Thus, in two or three years, the bushes will have resumed a different and more agreeable aspect. By the above treatment, these oraa- ments of the garden will always have a neat and healthful appearance, and the roses will be much finer. Where they are intended for the borders, they should never be allowed to get too high. In a border from four to six feet, they ought never to exceed four feet at the back of the border, and in front one foot, after being pruned; they can be kept down by the above method. It is not advisable to cut down rose bushes all at once, unless no regard is paid to flowering. The roses that are in grass-plats, and interspersed through the garden, would have a superior appearance in every respect, if they were kept and trimmed like small trees. They may be of different sizes and heights, according to the distance they are from the walk. A single stem may arise from six inches to six feet, with a head in proportion to the height of the stem. Where it is necessary to have them above two feet, and likewise to carry a good head, inoculation must be resorted to, which, in the months of July and August, will be fully treated of. All under two feet (except the weak growing kinds) will do on their own stems, taking care not to allow shoots to arise from the bottom during the summer. For directions for pruning climbing roses, see March and April. OF PLANTING SHRUBS, Efe. As soon as the frost is out of the ground, these should be planted, if the soil is not too wet. Where soil is binding, upon no consideratic » plant it while wet ; rather defer it until the end of March. Trees and shrubs, if they are well arranged, are the chief ornaments, give the most pleavare, and afford the greatest delight that we enjoy in uur gardens. Although they give no sort of nourishment, nor produce any edible fruits, yet they are particularly grateful, and conducive to our enjoy- ments. Our walks in summer would be oppressive, but for their agreeable shade; in the fall and winter, we would be o .9) 7 26 OF PLANTING SHRUBS, ETC. [Feb left exposed to the chilling winds, but for the shelter they afford. Likewise, they produce a great variety of flowers, a varied foliage, and are standing ornaments that give no great trouble. In the character of sereens, they are particularly useful, whether to hide disagreeable objects, or as a guard against the weather; or, if they are planted in masses at a distance, they soon become agreeable objects, frequently very much improve the scenery of the place, become objects of utility as well as ornament, and, in such case, afford the highest satis- faction. When formed so as to exclude offices from the view of the house, or for sheltering the latter, or for eonnecting the house with the garden, orchard, or any similar purpose, shrubs are both useful and interesting. Where many shrubs are to be planted, the disposing of them properly is a matter of considerable importance to the future welfare of the whole; and, whether deciduous or ever- greens be mixed or grouped, that-is, indiscriminately planted together, or the evergreens planted by themselves, as is fre- quently done, a regular and natural arrangement is indis- pensable for establishing ornament. Arranging, no doubt, depends very much on faney; still, there ought always to be plenty of evergreens planted, that the whole may be more cheerful in winter. If shrubberies were made to a great extent, the scenery would be much more varied and characteristic by grouping judiciously than by indiscriminately planting. However, in small flower-gardens and shrubberies, the latter has to be adopted. In such places, tall-growing kinds should never be introduced, unless merely as a sereen from some disagreeable object, for they crowd and confuse the whole. ‘The dwarf and more bushy sorts should be placed nearest to the eye, in order that they may conceal the naked stems of the others. Generally, when shrubs are planted, they are small; therefore, to have a good effect from the be ginning, they should be planted eloser than they are intended to stand. When they have grown a few years, and interfere with each other, they can be lifted, and such as haye died, or become sickly, replaced, and the remainder can be planted im some other direction. Keep them always distinct, one from another, in order that they may be the better shown eff. But, if it is not desired that they should be more Feb.] OF PLANTING SHRUBS, ETO. 27 thickly planted than it is intended to let them remain, the smail-growing kinds may be six or eight feet apart; the larger, or taller sorts, ten to twenty feet, according to the condition of the soil. Thick masses of shrubbery, called thickets, are sometimes wanted. In these there should be plenty of evergreens. A mass of deciduous shrubs has no imposing effect during winter; and, as this is not the proper season for planting evergreens (April, and the end of September, or first of October being best), small stakes can be placed in the des- tined spot. Planting in rows, or in any plan of a formal character, should, at all times, be avoided. In planting at this season, observe that the roots are not much exposed to the air, especially if the wind be high and sharp; but it is always better, if possible, to defer the busi- ness until good, mild weather. According to directions in November, the ground will be well prepared, and only re- quires a hole dug for the reception of the roots, which must be considerably larger, that the roots may not be in the least confined. Break the earth well at bottom, put in as much as will receive the plant from one to two inches (according to its size) lower than it has previously been in the Nursery. If any of the roots are bruised or broken, cut them off; then place the plant in the centre of the hole, breaking fine all the soil that is put in, at the same time shaking the stem a little, that the earth may mix with the roots; when full up, press all the soil down with the foot, that it may, in some degree, consolidate about the roots, and support the plant. Tall plants should have a good stake for support, and place a small bandage between the stake and stem of the shrub or tree, where the tie is made, to prevent the bark from suffer- ing by friction. Observe, always, before planting, if the soil is not suitable, to supply that which is congenial to the nature of the intended plant. When shrubs or trees are to be carried to any distance, the roots should be carefully kept from air, by tying damp moss, straw, or mats about them, as circumstances will admit: .the success, in part, depends on due attention being paid to prevent the roots drying before planting. Although we have given the above directions for planting in this month, it will frequently oceur that they can only be put into practice during the next, as this month is often the severest of the season 28 OF HYACINTH AND OTHER BULBS. [ March. OF HYACINTH AND OTHER BULBS. Towards the end of the month, if the weather proves favourable, the covering should be partly taken off from the Hyacinths, Tulips, and other bulbous roots. It sometimes occurs that, by careless planting in the autumn, they are thrown above ground by the frost, especially if the ground is inclined to moisture, and they not being deep enough planted ; if such is the case, cover them with decayed leaves, old tan, or soil, whichever is most convenient; if not done, the sun and air will overpower the bulbs, and although the fibres have hold of the ground, the flowers will be miserably weak. MARCH. As soon as the frost is entirely gone, uncover all plants or shrubs that have been protected, preserving carefully such of the materials as will answer the same purpose next sea- son. Cut off all decayed shoots, or such as have been hurt by the frost. The Lagerstreemias will flower in greater per- fection, if they are pruned closely; that is, cut the shoots of last year to within two or three eyes of the wood of the previous year, at the same time having regard to the regular and natural shape of the bush. Cut off the injured foliage of any of the evergreens that have suffered by the severity vf the winter, but leave every green part which is essential to the support of this kind of plants. It is expected that all pruning of the shrubbery 1s finished; if not, get all ex- peditiously done according to directions given in the preced- ing months. All work that gan be done in this month should not be delayed, such as hoeing, digging, raking, and clearing away all leaves and litter of every description that have peen brought or blown into the garden during autumn or winter. March. | OF FRAMING 29 OF FRAMING. Where it is desired to have the more showy aunuals early in bloom, it is necessary to prepare a hot-bed frame, for the purpose of bringing them forward. It is time, about the first of the month, to collect and prepare manure for the de sired hot-bed; and, as that operation, in many instances, is very imperfectly performed, a few observations on the subject may be useful. Take three parts of fresh hot stable manure, with one part of fresh oak leaves. Have a sufficient quantity to make the intended bed, or beds, from three to four feet high. Shake and mix up both together in a compact, conical heap, in order to encourage fermentation. If the weather is cold and windy, cover it with straw or leaves and boards, which is necessary to produce the desired effect. If fermentation soon takes place, it will need to be thoroughly turned over in eight or ten days. If any of it has become dry and musty from excessive heat, as you proceed, water the affected parts, pile all up neatly, and leave it protected in part as before. In five or six days more, it will have to be turned again, re- peating it until the first extreme heat has been over. In neglect of this, the heat, after making up the bed, will be vehement for a week or two, frequently destroying the vege- tative purity of the soil, and proving destructive to the seeds. Allowing the manure to come to a lively heat, having no unpleasant, rancid smell, proceed to mark off your intended bed, running it east and west, as nearly as possible, measure your frame, and allow the site of the bed eight inches, each way, larger than the frame: at the corners, place a stick or rod perpendicularly. The ground ought to be higher than that around it, to prevent water from getting into the bed, which, if low, must be filled up; or, if supposed that water may lodge there, a little brushwood might be put under the manure, which would keep it from being inundated. The manure must be built up square and level, shaking, mixing and beating it regularly with the back of the fork. When ycu haye it to the desired height (from two to three feet will be sufficient for annuals), leave the centre of the ped a little higher than the sides, thus allowing it more to subside. When finished, put on the frame and sash, or sashes, keep 3% 50) LIST OF CHOICE ANNUALS, ETC. [ March. them close until the heat arises, covering them at night with mats or shutters. As soon as you feel the heat increased, give air by tilting the sashes a few inches, to let off the steam and stagnated air, observing to close in the afternoon, and cover at night. If the heat is violent, about half an inch of air might be left during the night. In about three days, if all has been properly attended to, the bed will be what is termed sweet. Then put in about six inches of fine garden soil; if heavy, mix a little sand with it. Spread it level, and, when the soil is heated through, sow in small drills, from one-eighth to an inch deep, according to the size of the seeds; cover with very fine sifted soil. Some very small kinds do best when sown upon the surface. When sown, give gentie sprinklings of water until they come up, when it will be necessary to give air freely during the day, to prevent them from being weak, or damping off, which many of them will do if they have not air regularly admitted.

Though the above will bloom much earlier by being sown on a hot-bed, yet where that convenience cannot be obtained, they will all succeed treated as hardy annuals. After sowing, if the weather be clear, the sun acting on the glass will produce a too rapid evaporation of the mois- ture of the soil, and may otherwise affect seeds but thinly covered, which must be guarded against by shading with mats for a few hours during bright sunshine. In giving water, it ought always to be about milk-warm, and passed through a fine rose, to prevent the stems being broken or bruised. Weeds must be drawn out as soon as they ap pear March. | NARDY ANNUALS. 53 HARDY ANNUALS. Many annual plants, though of short duration, are pos sessed of much beauty of hue and elegance of form: they are farther valuable from their adaptation in filling up va- cant spots through the flower-garden or parterre. hey are, besides, of easy culture, many requiring nothing more than to have the seeds sown in the spot where they are to grow. The first sowing may take place about the end of the month, when the ground is prepared and the weather fine; but avoid it at all times when the ground will not pulverize properly. The neatest and most expeditious method is to take a rod about one foot long and one inch in diameter, rounding at the end, with which draw a circle from four to nine inches in diameter, and from one-eighth of an inch to an inch deep, according to the size of the seeds. Many very small seeds will grow best, if sown on the surface of fine mould. When sown, cover with fine mould, placing a small twig or tally, with the name, in the centre of the circle, to prevent mistakes either in sowing, planting, or hoeing. When they have grown from one to two inches, the first moist day should be taken to remove such as are too crowded, which can be gene- rally transplanted to some other situation; taking care to shade them a few days with flower-pots, or some other substitute. A few kinds do best with removing, such as Balsams, China Asters, Marigold, ten week stocks, Hibis- cus, Zinnias, and several others of a free-growing and strong-wooded nature. Annuals are such plants as grow from seed, flower and perfect their productions, and then die within one year. The following sorts are well deserving of culture :— Adonis miniata, Flos Adonis or Pheasant’s eye, red. Amaranthus caudatus, Love lies Bleeding, red and yellow variety. hypochondriacus, Prince’s Feather, red. Amaranthus tricolor; three-coloured Amaranthus should be sown on rather poor soil—on rich soil it has little eauty. ne uty — —_ B4 HARDY ANNUALS. [ Marck. Brachycome ibcridifolia, fine dark blue.

Viscaria oculata, violet viscaria. Viola tricolor, Pansy or Heart’s-ease, require very rich soil, and should be shaded from hot sun; if sown early in the season, they will flower profusely in the autumn. For other varieties of Annuals, see list adapted for hot-bed sowing. We have omitted many not agreeing with our cli- mate, or those very common; for such, we refer our readers to the lists published annually by respectable seedsmen. BOX EDGINGS May be planted any time this month, or beginning of next, which in most seasons will be preferable. We wili give a few simple directions how to accomplish the work. In the first place, dig over the ground deeply where the 86 GRASS AND OTHER EDGINGS. [March edging is intended to be planted, breaking the soil fine, anu keeping it to a proper height, namely, about one inch higher than the side of the walk; but the taste of the operator will best decide, according to the situation. Rake the surface even, and tread it down with the feet, or beat it with the spade. Where it gives most, continue to add, keeping the surface at the desired height. If the edging is to be in a direct line, either on a level or inclined plane, you may be correctly and simply regulated by making the desired level at each end of the line. ‘Take three rods, about four feet rong each, having a piece of one foot to cross at one end, two of these pieces painted black, the other white. Have a black one at each end of the line on the level; take the white one for the centre, going along the line, and, about every twenty feet, level a spot to the exact height, which will be seen by look- ing over the top of the rods from one end. Having found the level, drive in a peg to it, so that no mistake may occur ; beat and level between them, leaving a smooth surface. This being done, strain the line, and with the spade proceed to cut out the trench perpendicularly on the side next the walk, six, eight, ten, or twelve inches deep, according to the length of the plants. Afterwards take the plants, and cut the tops even, with the knife or shears, at the same time shortening the roots. Then with the left hand next the line, plant forward, keeping the tops of the plants level, and from one to two inches above ground, keeping the plants close, according to the required thickness. Put in the earth as you proceed, and tread it firm, then rake the surface even, and with the spade beat it smooth. If the weather sets in very dry, the box will be the better of a few waterings. Some- times boxwood is planted without roots, but it seldom gives satisfaction, not growing equally. GRASS AND OTHER EDGINGS. Grass verges for walks and borders, although frequently used, are by no means desirable, except where variety is re- quired; they are the most laborious to keep in order, and at best are inelegant, and the only object in their favour is their being everywhere accessible. Iris humilis, Viola tri- color, thyme, Sea Pink (Stattice Armeria), Mignonette, March. | HARDY BIENNIALS. 37 Phlox subulata, and Plox procumbens, all make tolerable edgings. In the Southern States, Huonymus Japonica, kept closely sheared, will make a very handsome green edging. HARDY BIENNIALS. Biennial plants are such as are of two years’ duration Being sown this year, they flower, seed, or fruit next year, and soon after decay: the seeds should be sown about the end of this month or beginning of next, either in the spot where they are to remain or a compartment by themselves, regularly marked, and to be transplanted in May or Septem- ber. When they appear above ground, thin them out dis- tinctly, that, when they are to be removed, a little earth may adhere to them: and if sown where they are to stand, leave only three or four plants in each patch. The following list are a few of the free-blooming and more elegant sorts :— Agrostemma coronaria, Rose Campion, blooms all summer. Althea rosea, Hollyhock, and all its varieties, very showy in July and August. When any very desirable variety is procured, it can be multiplied by dividing the root. Antirrhinum majus, Snap-dragon, and its varieties, require to be protected during winter with a few leaves or litter. Cantua coronopifolia, flowers in August and September, beautiful scarlet, delights in dry gravelly soil Ipomopsis elegans. QMampanula media, dark blue Canterbury bell Campanula media, semi-pleno, half double | Bloom in June Canterbury bell, and July. Campanula media, alba, white Canterbury bell, Campanula thyrsoides.

Papaver nudicaule, naked-stemmed yellow Poppy. Scabiosa atropurpurea, musk-scented Scabious. Silene multiflora, many-flowered Catch-fly. There might be many other beautiful biennial plants enu- merated, which are justly considered worthy of attention ; but most of them do not withstand the severity of our win- ters, although very much prized in England. PERENNIALS. In evary flower-garden, there ought to be a good selection of these plants. ‘They are lasting ornaments; and, when judiciously selected, will give yearly gratification. In mak- ing a choice, a view should be to have those that flower abundantly, are of free growth, beauty, and continuation of bloom. It would go beyond our limits to give an extensive description of any, but a few remarks on some of the finest, with their names, are indispensable. Adonis verndlis is a fine border-flower, and will grow in any common soil; flowers large, yellow-rayed, having in the rays about twelve petals; leaves much divided; blooms in April and May. Anemdne, Wind-flower. Several fine species, with flowers from one to three inches in diameter, very celebrated in Hu- rope, though succeeding poorly with us except in cool lati- tudes. A. alpina, large white. A. japonica, rosy purple. 4. palmata flore-pléno yellow; A. stellata versicolor, various March. | PERENNIALS 39 coloured; A. pavonina flore-pléno, scarlet; A. narcissi-flora white. Any of these are very desirable, Antirrhinums, Snap-dragon. All the varieties of A. madjus are esteemed in the flower-borders; the pure white, bright red, rich crimson, and variegated, are very showy. A few of the species, A. mdlle and A. stculwm, where there is variety required, deserve a situation. The flowers are all large, and similar to the snout of an animal. Anthéricum lilidstrum, St. Burnos Lily, is an excellent liliaceous plant, with orange-yellow flowers, blooming in June, July, and August and will grow in any common garden soil, Asclépias. The finest of this genus are native plants, and are highly esteemed in Europe, but frequently rejected with us, because “they are wild plants.” A. tuberdsa has beautiful orange flowers, and delights in dry situations. A. rubra, A. nevia, A. purpurdscens, and A. incarndta are the finest of the family. It is best to plant A. tuberdsa in October. Aconitums, Wolfsbane, one hundred and twenty-eight distinct species, with several varieties. Many of them are of consequence and beauty; the flower-stems rise from one and a half to six feet upright, and strong, furnished with many palmate and digitate leaves, terminated by spikes of blue, yellow, or white flowers, similar to a hood; hence the name of Monk’s hood is often applied to them. They are scarce in collections; but, in a few years, we have no doubt but many of them will be plentiful. The finest species are A. specidsum, A. sieboldii, large dark blue, A. pyrenaiacum, branching blue, A. napéllus, A. ventstum, A. pyramidale, A. lycétonum, A. versicolor, or variegatum, and A. grandi- florum. They flower from May to September, and will grow in any common garden soil. The roots of A. napéllus are like small turnips, and are poisonous. ‘They like a little shade and rich soil. Réllis perénnis horténsis, Daisy. We might almost say _ with another, “‘ Every one knows the Daisy.” It is named from being pretty, and is perfectly hardy, though generally kept under cover. They delight to have a shaded situation during summer, to protect them from the sun, which, as it were, scorches the roots. There are many double varieties in the gardens, which flower early. The one called Crown ar 40 PERENNIALS. [ March Carnation Daisy is twice the size of the common varieties, and has white and red petals alternately and very double. The Belgian varieties are very numerous, but few of them are equal to our old sorts. Loamy soil, inclined to moisture, is best adapted to their growth. Campdnula. This genus affords very many ornamental plants for the Flower-garden and Shrubbery, and they flower superbly during the summer, agreeing better with our climate than with that of EKurope. Many have two successions of flowers, C. persicifolia alba pléna; C. persicifolia carilea pléno; C. urticifolia, white. Of this last there is also a double variety. C. nobilis, large pale lilac, spotted with erim- son; CO. nobilis alba, white, spotted with crimson; C. grandis, fine bright blue. C. speciosa; C. glomerata; C. versicolor, with several others, are worthy of a situation in every garden. Their roots are strong, fleshy, and fibrous. They are easy of culture, and will retain their situation in the severest of our winters. C. grandiflora is now Wahlinbérgia grandiflora. It has superb large blue flowers, stems are slender, and require support. Cheirdnthus Chéiri vulgaris is the ccmmon garden Wall- flower. There are about ten varieties of it, all admired for their various colours and agreeable odour. The common variety survives the mildest of our winters. The most esteemed variety is hamdnthus, Double bloody. They should all be protected by a frame. C. mutdbilis is a beautiful species; it has many shades of colour, from lilac to dark purple. The flowers are on extending racemose spikes, blooming from April to June; it requires a light rich soil; is a half-shrubby ever- green plant. Chélone. This genus belongs entirely to this continent, and possesses many fine species. It is a matter of astonish- ment that they are not more cultivated and sought for in our collections. C. glabra; C. obliqua; C. barbdata; C. atro- purpurea; C. pulchélla; and C. specidsa; are all handsome, and flower from May to September; corolla large, ringent, ventricose; flowers in spikes or panicles. Chrysénthemums. 'The Chinese Chrysanthemum was first introduced to the garden of the King of France about sixty years ago, and shortly after about ten varieties were sent from Canton to England, a gardener having been sent out expressly for them, so much were they admired by Sir Abraham Hume. Murch.) PERENNIALS. At There are now over two hundred varieties, far excelling the old sorts, and even surpassing the critical anticipations of the most ardent connoisseurs. A few years ago we would have been satisfied with a good dozen, but now four times that number will not embrace all their beauties which have origi- nated in France, England, and the United States. The fo:low- ing list we can admit as now unrivalled : Large Flowered. Annie Salter, fine yellow. Baron de Solomon, rosy crimson. Defiance, lemon yellow. Julia Langdale, rosy purple. Liencour, lilac and orange. Magnificent, blush. Mrs. Cope, dark crimson purple. President de Abbeville, crimson. Queen, early blush. Racine, straw tipped with bronze. Sphinx, bright claret. William Penn, creamy white. White Perfection, pure white. Pompone or Lilliputian Flowered. Cybelle, amber and gold. Uarriet Lebois, rosy carmine. Hendersonii, fine early yellow. Henriette Chauviere, blush. La Fiance, white. La Gitana, blush pink. Larty, rosy crimson. Mignonette, rose. Paquerette, white shaded crimson. Sacramento, dark yellow red centre. Triomph de Bordeux, shaded blush. Vartigene, crimson. To grow these in perfection, they require rich light soil, and about the end of this month the roots should be lift- ed, divided, and planted into fresh soil, either by giving * 42 PERENNIALS. [ March. them a new situation, or changing the earth they were in Two or three stems together are quite sufficient. The flowers, by the above treatment, will be much larger, more double, and finer in colour; where they are wanted to grow low and bushy, top them in June, but not later than the first of July Where the soil is rich, and the plant having only one stem, by topping it, makes a beautiful bush. They are in flower from the first of October until severe frost ; thus beautifying our gardens at a season when they would be destitute of one single attraction. If the season be dry, to water them with liquid manure will add to their vigour. They are all natives of China, and greatly esteemed by the Chinese, who only allow a few blooms to come out on the top of each stem, thereby having the flowers much finer. Clématis, Virgin’s-bower. A few species are good herba- ceous plants, of upright growth and blue flowers, C. integri- folia; C. angustifolia ; and C. erécta; they grow best in light soil. Coréopsis, chiefly native plants, and free-flowering ; colour principally yellow; flowers rayed. OC. tenuifolia, C. verti- cilldéta, C. discolor, and C. tripteris, are the finest of the genus, and will grow in any common garden soil. Delphiniums. There are some showy border flowers of these, of strong growth. The leaves are much divided; the flowers in terminal spikes; colour blue, purple, pink, white and yellow, with various shades. D. grandiflorum, and its varieties, are the best of the genus. D. intermedium, and its varieties, D. eldtum, Bee Larkspur, from the ringent part of the flower being very like a bee, D. Chinense, dark blue, D. Barlowii, large bright blue, and D. montdnum, are good varieties, and easily cultivated. When the plants become large, they ought to be divided, and planted in fresh soil. They are in bloom from May to September. Didnthus. Some of the species of this genus are the most prominent of the flower-garden, not only for their beauty, but also their fragrance, which is peculiarly grateful, especially in the well-known and celebrated Pink and Carnation, with the Sweet William, which was esteemed in the days of old “for its beauty to deck up the bosoms of the beautiful, and garlands and crowns for pleasure.” The finest species are D. barbatus and D. barbatus pléno, Sweet William; D. discolor; D. chinénsis; D. alpinus; D. supérbus; D, March. | PERENNIALS. 43 caryophyllus, from which have originated the Picotee and the Carnation; D. plumdrius, from which originated the Double Pink. Several of these, although they will stand the severest cold, have to be protected in frames during winter, to have them in the perfection of beauty. For the character of a Pink and Carnation, see May. Dictémnus. 'Two species of this genus, D. fraxinélia and D. dibus, have been cultivated and esteemed upwards of two hundred and forty years. A plant of the first of these spe- cies, when gently rubbed, emits an odour like that of lemon- peel; and when bruised emits a balsamic scent, which is strongest in the pedicles of the flowers. They have glands of a rusty colour, that exude a viscid juice, or resin, which exhales in vapour, and in a dark place may be seen to take fire. Its flowers are red, those of the other white, in loose terminal spikes; the flower has five petals, clawed and unequal, with glandular dots; in bloom from May to July ; delights in sandy loam. Dodecdtheon. This is a native genus, and commonly called American cowslip. The generic term, a name of the Romans, signifying twelve gods or divinities, is applied with great absurdity to a plant, a native of a world the Romans never saw nor had any idea of; neither resembling in any par- ticular the poetical fancy of their writers. The most admired species is D. média; the flowers are in umbels, on a pedicle, from six to twelve inches high ; the corolla is rotata reflexa ; colour light purple, bottom of petals lake and yellow; bloom- ing in May. The white variety is very much esteemed, and surpasses the preceding. The ground is pure white, the bottom of the petals the same as the other. There is also a spotted variety found on the banks of the Missouri. They delight in brown loam, a half shady situation, inclining to moisture. The foliage soon decays after flowering. Dracocéphalum, Dragon’s Head, about twenty species, mostly ornamental. D. virgintcum is a profuse blooming plant, with bluish-pink flowers, and grows about four feet high. D. argunénse is a superb dwarf, with large dark blue flowers. Dielytra spectabilis, a new and very splendid Fumwort of dwarf habit, with a profusion of large delicately shaded pink towers during June and July. Ewpatériums. These generally are native plants, not 44 PERENNIALS. [ March. worthy of notice here, except for two species. LH. calestt- num has syngenesious flowers in flattened panicles, colour fine light blue, blooming from September to November; de- sirable for its beauty at that season. #. aromdticum may be cultivated for its spicy odour ; flowers white, in loose terminal panicles ; blooming from August to October. Hither of them will grow in common soil. Funkia, Japan Day Lily, three species, all beautiful. F ceriléa, with blue flowers. . japdnica, pure white, and F. variegata, with striped leaves and flowers. F. laurifolia, early blue. This genus has been separated from Hemerocdilis. Gentidnas, a genus of very showy plants, and flower in great abundance. The flowers are tubular and inflated; colour generally blue. A few species are yellow, and some white; flowers in whorls, terminal or solitary. They grow best in a light rich soil. G. hitea, G. purpiirea, G. septém- fida. G. acailis is a pretty dwarf-growing species, the flower dark and light blue; interior of the corolla spotted ; has a succession of flowers from April to June. These are fine exotics, but may give place to our native species, such as G. Catesbet; G. ochroletca; G. incarndta; with several others, and @. crindta, which is a biennial, and finely fringed ; colour light blue. Géum. There are only four species that are worth culti- vation, namely, G'‘. guéllyon, once G. coccineum; G. splen- dens, G. Wicea, and Gt. hybridum. G. urbdnum is some- times cultivated for its roots, which, when chewed, sweeten the breath. They are all of easy culture. G. quéllyon and splendens flower from May to October, and are very desirable plants for the borders, and much esteemed in Europe. Hemerocdllis, Day Lily; three species, H. filva, H. gra- minea, and H. Sieboldii, fiower well, and are remarkable among the border flowers for their large yellow or copper- coloured corollas, some of them about six inches in diameter ; bloom from May to July, and will grow in almost any soil There is a plant known in our gardens as Hf. cwrilea, which is Fuinkia cerilea, and has a campanulate corolla, with a cylindrical tube ; flowers in spikes ; leaves ovate, acuminate.

The flowers are about six inches in diameter, flowering up the stem, either solitary or m small bunches. H. specidsus is the most splendid, and deserves a situation in every garden. The roots in winter ought to be covered with litter, tan, or sawdust; but a better method is to lift them, and put them in the cellar, covered with dry earth, and kept from the frost. All the above-mentioned species are improved by being protected during winter. Iris, Flower-de-lis, has many fine species of various shades and colours, J. subiflora, I. nepalénsis, I. Pallasii, I. pallida, I. cristata, I. arendria, I. furedta, I. germdncia, I. floren- tina, I. vérna, and Z. susid@na. The last is the finest of the herbaceous species; the flowers are very large and curiously spotted with brown; it stands the severest of our winters unprotected. The root of L. florentina is the orris root of the druggists. They are all of easy culture in any loamy soil inclining to moisture. The bulbous species will be treated of in September or October. Corolla six-petalled, three erect and three reclined alternately ; proceeding from. spathes or sheaths with flowers in succession. Liatris is a genus of native plants, containing several fine species, J. sguarrosa, large purple heads of beautiful flowers ; LL. élegans; L. paniculata. L. macréstachya, now L. spicata, is a fine large-growing species. They have syngenesious pur- ple flowers in long close spikes, differing from other spiked- flowering genera by blooming first at the extremity. They grow best in strong heavy soil. Lychnis. Three species are very desirable in the flower borders. JL. chalceddnica has bright searlet-crowned flowers ; the double scarlet variety is splendid; there is also a double white variety; L. falgens and L. fldsjovis. They ought te be frequently lifted and planted afresh; or they will dwindle to nothing. The best time is when they begin to grow. There is a plant known in our collections as Lychnis flds- cuctli, ragged Robin or French Pink, which is now Agros- témma fids-cuctli ; it is a fine and showy border plant, with double red flowers; a double white variety of it has been recently introduced, of the same character, with the additional quality of blooming the whole season.

We are rather in- clined to think that those who have them do not give them the treatment they require yearly to perfect their bloom They should now have the surface earth taken off about half an inch down, and fresh soil added, which will cause them to put on fresh fibres about the upper part of the roots, and greatly increase their growth. The frame in which they are placed should now face the east, as the sun will be too strong for them; and about the end of the month turn it to the north. The glass of the frame may be white-washed, which will partially shade them from the sun, that being their de- light. Give them water sparingly until they begin to grow, and never water them over the foliage previous to flowering, as water injures that fine meaty-like substance found on many of the sorts, and which so greatly improves their beauty. Defend them, therefore, from rain and high winds. ‘To have them flower strongly, only one flower-stem should be allowed to grow. ‘The first one that shows is generally the best. At all events, leave the strongest, and cut off all the others, or only nip off the flower pips, which answers the same end. Never keep the sash off during the night, in case it rain before morning. RANUNCULUS AND ANEMONE. The frames of Ranunculus and Anemone must have plenty of air, and give frequent sprinklings of water. The sashes er shutters should be taken entirely off every mild day, and 5* 54 ROSES. [ March. in fine nights leave them exposed to the dew.

This is the most favourable month for planting all kinds of garden roses, which must be done as soon as the weather opens, and the ground is in a proper state. The earlier they are planted the more perfect they will flower. Never delay planting when there is an opportunity; for, if delayed until the leaves are expanded, the bloom will be much weakened, and the probability is there will be no flowers, and the plants meet with a premature death. It has been said, ‘There is a particular advantage in planting some every ten days, even to the middle of May; for the flowering of them may be re- tarded in this way, and the bloom of these delightful shrubs continve for a much longer period.”” One moment’s reflec- tion will convince us that nature, while in her own element, will not be retarded, suppose there was no danger of instan- taneous death to the plants. he artificial means that might be judiciously adopted, with which we are acquainted, to keep back the blooming of hardy plants, is to lift them as soon in spring as is practicable, put them in boxes of earth, and then place them in the driest part of an ice-house, until the desired time of planting, which may be delayed as long as the required time of flowering. ‘This will be found a true method of retarding the flowering of roses especially, and not going counter to the rules and principles of nature. There are many beautiful varieties of the garden rose in cultivation, the names of the finest of which we will give in the following catalogue :-— ; African black, very dark crimson, compact and very double.

It is also called Hogg’s Yellow Rose. 7 It has long been questioned whether the Moss Rose was a dis- tinct species, or merely a seminal variety of the Provins Rose. I perfectly agree with the latter opinion—for in June, 1836, I saw in my nursery a plant of the Moss Rose with a large shoot that had sported back to the Provins Rose, and entirely destitute of moss on either shoots or buds, We have no faith in black and yellow Mosg Noses; al] we have seen for such have proved false to their character 56 ROSES.

Yellow Persian, the finest yellow rose grown. We mention these as fine; but, among several thousand cultivated varieties of the garden rose, there must be many of equal, if not surpassing beauty; of /tosa spinosissima, there are about five hundred varieties; Rosa gallica, two hundred ; /?. centifolia, one hundred and fifty; R. damascéne, above one hundred; /. alba, fifty; R. rubiginosa, thirty ; and of various sorts above eleven hundred. In several indi- vidual collections of Europe, there are cultivated above fifteen hundred species, sub-species, and varieties. When planted, they are too frequently crowded indiscri- minately among other shrubs, which prevents them having the effect they would have if planted singly or grouped. They vary in size, in different sorts, from one to ten feet. When planted in the latter method, they should be assimi- lated in size of leaves and manner of growth, with the great- est variation of flower; or, if planted in small patehes, each distinct in colour, will have a very picturesque effect. Another desirable and fanciful method is to plant them in figures, with edgings of wire, willow, or any other substitute, in imitation of basket-work, which is called ‘“ baskets of roses ;” the ground enclosed in the basket margin to be made convex, which will present a greater surface to the eye; the strong March. | ROSES. oT thoots to be layered, or kept down by pegs m tne gro md, having the points of the shoots only to appear above the aoil, which should be covered with moss. With this treatment, in a few years the whole surface of the basket will be covered with rose-buds and leaves, of one or various sorts. If two or three of the larger growing sorts are taken, such as Moss or Provins, they may be trained so as to cover a surface of several square yards. A modern invention in the cultivation of the rose is to grow them in shape of trees, by budding on strong-grow- ing kinds at different heights from the ground, according to taste, and the purposes intended. If budded on Rosa céd- nina, or Dog Rose, they are much more valuable: it is a last- ing and strong-growing stock; and the worst of all stocks is the Boursalt rose, and it is too frequently resorted to, being easy of propagation. They will form in a few years hand- some round heads, which will flower more freely than by layers, or trained on their own stalk. They are particularly desirable among low shrubs. When planted, they should be well supported by strong rods, to prevent the wind from de- stroying them. If any of the roots have been bruised in lifting, cut off the bruised part with the knife, and likewise shorten the young shoots; breaking the earth well about their roots when planting. The rose has been an esteemed shrub among all civilized nations. The flowers are double, semi-double, and single; the colours are pink, red, purple, white, yellow, and striped, with almost every shade and mix- ture; the odour universally grateful. This plant is sultivat- ed in every garden, from the humblest cottager to the loftiest prince, and by commercial gardeners in Hurope extensively, for distilling rose-water, and making the essential oil of roses. They delight in a rich loamy soil, and require plenty of moisture while in a growing state. Those sorts which throw up numerous suckers should be lifted every three or four years, reduced, and then transplanted. When thus removing unem, avoid, as much as possible, exposing their roots; and when newly planted, mulching is of considerable advantage ; that is, putting half-rotten stable-manure on the surface of the ground round their roots, which prevents evaporation, and keeps up a constant moisture. If this were done in general to our roses in dry seasons, it would greatly improve their flowering. For Chinese and other roses, see next month. 58 ORNAMENTAL FLOWERING SHRUBS. [ March. CLIMBING ROSES. This is the best time to prune ever-blooming climbing roses, such as Champney, Noisette, &e. Many of these, when allowed to grow year after year without pruning, be- come unsightly; they never bear flowers on the old wood, that is, wood of three or four years. Having a tendency to throw out young shoots from the bottom of the stem, the old wood should be cut out, thus encouraging the young wood, which the second year bears the most and finest flowers In severe winters, the extremities of the shoots are frequent- ly killed, and we have often seen all the wood black or brown, and apparently dead. When that is the case, it is best to leave it until they begin to grow, which will show what is dead or alive, when they can be pruned to better advantage. DECIDUOUS ORNAMENTAL FLOWERING SHRUBS. The earlier the planting of these shrubs 1s attended to in this month, the more will their growth and flowering be pro- moted, having all finished before the buds begin to expand. (Hor kinds recommended, see list, end of the volume.) They should never be planted too thick; but leave space for them to grow as they respectively require, and according as they are designed for open or close shrubberies, clumps, or thick- ets. Have all in readiness, that it may be done with as much expedition as possible, to prevent their roots from being dried by the sun and wind in time of planting. Make the holes intended for their reception round, capacious, and deep enough to hold their roots, without confining them in the least, and loosen well the bottom, putting new and fresh soil under their roots, breaking and puiverizing it dur- ing the operation, and frequently shaking the plant as you progress in filling up. When done, make all firm with the foot, leaving a circular cavity to hold the water they will require during dry weather. Give rods, and tie with bands all that need that support, before they are left, lest they shoull be neglected. Cut off any of the bruised roots or irregular growths of the branches. hiarch.] GRASS-PLATS AND WALKS. of GRASS-PLATS AND WALKS. A most wonderful renovator of grass-plats may be found in Guano. Take at the rate of one pound to twelve square yards, mix it with double the quantity of sand, and before rain in April or May, sow the mixture over the grass; ina few days its effects will be seen. Where grass lawns are poor, and of a pale yellow colour, about four hundred weight to the acre, mixed with sand, plaster, or dry earth, will effec tually restore them to a luxuriant verdure. Rake and sweep off from these all litter, and worm-cast earth, and give an occasional rolling to settle the ground, and render the surface smooth where the scythe is to be used. The grass will likewise grow better by rolling it where the frost has partially thrown it out, and add greatly to its beau- ty. Cut the edgings with an edging-iron or spade, so that the whole will have a finished appearance. If any new turf is required to be laid down, this is a very good time to do it, before vegetation is strong; as the turf that is now laid will have taken root before the dry season commences. Where a great extent is to be done, sowing might be adopted; but it will not have the effect of turf under three years, and dur- ing that time must be carefully cut, after the first season- every three weeks, while growing; nor must it be too fre quently walked upon. White clover and true perennial rye- grass are the seeds most proper for sowing. The ground must, in the first place, be all equally made up, and levelled with the spade and rake; not “cart-loads of soil laid down and levelled,’ which would finally become very uneven, ana wouida need to be lifted and relaid next year. The best turf is that of s close-growing pasture or common, free from all kinds of «.seds or strong roots, and the grass short. To cut it expeditiously, be provided with a turfing-iron; but if that cannot be convenicntly had, a spade may do very well. Strain a line tight, cutting the turf lengthwise, at equal distances, from twelve to eighteen inches. Next draw the line across, cutting from one and a half to two feet; then cut them up with the spade, about one and a half inch thick. In laying, jom them close and alternately; when done, beat them firm with a level woolen beater, and roll with a heavy roller. Grass-walks, in the last century, were very popular; but 60 GRAVEL WALKS. [March time having put them to the test, they are found unfit for walking among or using in any manner, almost for one-half of the year; therefore, not answering the purposes intended. They require great attention to keep them in order; and if not always neat and clean, they are a disagreeable object in a garden; but, when they are well dressed, their effect is very enlivening. Where they are desired, prepare the ground ag above directed; making the walk a little higher than the adjoining borders, to prevent the earth from being washed on it by the rain. Allowing the walks to be six feet wide, make the centre five inches higher than the sides, or about seven- eighths of an inch to the foot, whatever the breadth may be, which will form a gentle declivity to throw off the rain. When laid, beat and roll it well; cutting the edge neat and even. Water frequently, if the weather sets in dry. To keep grass-walks or plats in order, they should be mown once every three or four weeks, from May to September, and the grass each time swept clean off. When the grass is allowed to get long before being cut, the roots become tender, and die when exposed to the sun; at last the grass is all in spots, and in another year requires to be relaid. GRAVEL WALKS. A practice once existed of turning these into heaps, ot ridges, during winter, to destroy weeds, &c. But this has almost been given up as unnecessary, unsightly, inconvenient, and not doing any material service. Where the surface of these has become foul, irregular, or mossy, they had better be turned over four or five inches deep, where the gravel will admit of it; but if not, hoe and rake them perfectly clean, give a new coat of gravel, and pick up any stones that you think too large; then give them a good rolling, applying it frequently after showers of rain. When they are well attended to just now, they will look well all the season; but if neglected, they take more labour, and are never in such good condition. Fancy-edgings of Thyme, Thrift, Lavender, and Violets— (Daisies may be used if the situation is shaded). The whole of these may be planted by the line with the dibber except Thyme, which lay as directed for Box. See this month, March. | OF GRAFTING. 61 under that head. Any time in this or beginning of next menth will answer to make edgings of these; and if dry weather occurs before they begin to grow after planting, they must have frequent waterings until they have taken fresh root. Thyme requires to be dressed twice during the season, to keep it in order. OF GRAFTING. There are four methods of grafting. It can be applied to all kinds of shrubbery, choosing a common species from the same genus that the sort belongs to, which is intended to be multiplied. The one we will describe is whip or tongue grafting, which is the preferable and most expeditious plan with all deciduous shrubs or trees. The stock upon which it is performed must be slender, from two-thirds of an inch te any diameter suitable to the thickness of the graft. Having headed the stock at a clear, smooth part, slope it on one side with a sharp knife at a very acute angle, make a slit on the lower side of the slope about an inch downward to receive the tongue or wedge of the graft or scion. Secondly, having the prepared scions cut into lengths of three, four or five eyes, take one which matches the stock in size, and slope the bottom of it so as to fit the stock, that the rinds of both may correspond exactly, especially on one side and at bottom ; make also a slit upward in the graft, like that in the slope of the stock, so that the one may be inserted in the other as evenly and completely as possible. Let the graft be carefully held in its due position, while a bandage is applied. Take strands of Russian mat, and bind them in a neat manner several times round the stock and graft. Lastly, cover the joint with well-worked clay; ccat from half an inch below the bottom of the graft to an inch above the top of the stock, and to the thickness of half an inch all round; finish it in an oblong globular form, taking care to work it close, that no air may penetrate. If the clay is covered with moss, it will partially prevent it from cracking. The grafts will have taken when they begin to grow freely : then the clay may be broken off, and the bandage loosened, and put on again, but not so tight as formerly; give the grafts a stake for support, tying then thereto to prevent 6 62 ANNUALS. [April accidents from the wind. Allow no shoots to arise from the stock. APRIL. THE ambition of every amateur and gardener, during this month, is to be at the head of every department, and over every spot. The operator’s activity, in this month, almost regulates the whole season. Hvery weed ought to be cut down as soon as it appears, and the proverbial saying will be realized, “A garden that is well kept is easily kept ;” one hour of laborious industry now will save two in the heat of summer. A wet day need cause no loss of time: prepare rods, bands, and tallies, to be in readiness when required Many, in the height of bustle, never finish properly as they proceed, which is the worst of practices. Every operation ougkt to be completely and properly finished before another is taken in hand, which wil! ultimately prove the quickest and best method to work upon. Let digging, hoeing, and raking be done as expeditiously as strength will allow, that the time may be devoted, for a few wecks, to the beautifying of the garden and parterre, bv sowing and planting. ANNUALS. Those that are tender and were sown last month, according to directions, will be ready to prick out into another glass frame. Keep them a few inches apart, to let the air circu- late. Give them frequent sprinklings with water, and shade them with a mat for a few days, until they have taken fresh root ; then give them plenty of air, and by the first of next month, expose them, night and day, to harden the plants for the open ground. of its history will assist in giving a key to its cul ture. The plant was first discovered by Humboldt, in Mex- ico, growing in sandy plains three thousand feet above the level of the sea. The date is not precisely known, but supposed to be about 1785-6. Indisputable authority, how- ever, speaks of its being introduced into England in 1789 ; but was lost and again introduced in 1803, from Madrid, by Lady Holland; from which period till 1830 it had but little notice in cultivation. Indeed, it seems to have been reserved for the intelligent growers of the last few years to bring it into general notice; and if we take a retrospective view of the rapid progress of Dahlia culture within these last five years, we will be led to exclaim, ‘ Where will ali this termi- nate?’ But time alone can solve the question ; at present it is impossible to come to any satisfactory conclusions. Only a few years ago, and who would have conceived the idea of having tipped, striped, and spotted Dahlias of almost every hue and colour; and although historical writers on the genus alluded to the improbability of a blue flower ever being pro- duced, yet it is not unreasonable to imagine that ere long we will have flowers beautifully and distinctly striped with black and white, and even combining the gaudy colours of the tulip, or the choicest hues of the carnation; perhaps the criteria of character may change to those of huge globular forms or balls—nay, even the odour of the Rose or the Jasmine may be imparted, and what then? Only let amateurs and culti- vators persevere with the spirit they have done during the last few years, and we think all we have advanced will be realized. Propagation.—-This operation may be performed in various ways, either by division of the root, by cutting off the young shoots, or by grafting. For general planting division of the g* 102 PROPAGATION BY CUTTINGS. [May root will be sufficient; about the first of the month the old root, entire, should be planted in some warm and sheltered spot of the garden, covering it with sand, vegetable mould, or any light soil; in about two weeks the eyes or young shoots will have sprouted: then it will be properly seen how they ean be most carefully divided; the root should be carefully cut into as many pieces as there are eyes or sprouts, leaving only one tuber to each, when they can be planted into the situation appropriated for their blooming. Propagation by Cuitings.—Prepare a hot-bed in March, as therein described, and place a frame and lights of the required size upon it; scatter over the surface of the bed four or five inches of sand, old bark, or any light soil; after four or five days, the fresh steam will have subsided, when the roots may be laid thereon, covering them (but not over the crowns) with light sandy soil; but where large pots can be oStained, I prefer planting them in the pots; by this means tke plants are kept distinct, and can be taken out at any time and examined. They should be frequently sprinkled with water that is partially warm; and if, after they are thus placed in the bed, a rank and dense steam should arise, the lights should be slightly raised both night and day, till it subsides; and if the nights are cold, cover the lights with wats or shutters. This gentle bottom-heat will speedily in- duce the eyes to grow, and when the shoots have attained the height of three or four inches, they should be cut off close to the base, which makes the best plant. After the cuttings are taken off, pot them singly into very small pots filled with light sandy loam, containing a good portion of black earth from the woods, and placed in another moderate hot-bed, and give a gentle supply of water. Particular care must be paid to shading them from the violent rays of the sun, for if they are once exposed, they seldom recover: in this state they should continue till they have formed their roots, which, in a temperature of from sixty to seventy degrees, will be in from two to three weeks. Where a great stock of any par- ticular sort is wanted, the cuttings should be taken off just below a joint, leaving two or three eyes at the base of the shoot, which will again speedily produce new shoots, that can be again removed in a similar manner. When the plants are rooted, they may then be considered established, and all that is necessary is, to shift them inte May_| SOIL—ARRANGEMENT. 102 larger pots as they require; and gradually inure them to a lower temperature, till they can endure the open air, which will not be before the middle of May. Propagation by Grafting.—Where only a few plants are wanted, this is a very successful method, as an operation can be conducted in the office or parlour window. The cutting intended for the graft should have about three joints; when obtained, select a good tuber without eyes from any common sort, and with a sharp knife cut a slice from the upper part of the root downward about two inches in length, and about half an inch in depth, and then cut it off horizontally, leav- ing a ledge whereon to rest the graft; next cut the graft sloping to fit, and cut it so that an eye or joint may be at the bottom of it to rest on the aforesaid ledge. After the graft has been firmly tied, a piece of clay should be put round it; pot the root in fine soil, in a pot that will bury the graft half way in the mould, and cover it with a glass (a large tumbler will do), and in two weeks it will have taken root; the glass may then be removed, and the plant gradually inured to the open air. Soil.—As far as my observations enable me to judge, the soil best adapted for the Dahlia is a sandy loam, not reten- tive of moisture, and not too rich, as they will grow to leaves and branches, producing few flowers, and even then imper- fect: not too poor, as in such they will be very indifferent, meagre in size and general appearance. Where soils are rich and heavy, a portion of sand or gravel should be mixed in the soil where they are planted: but if poor, incorporate with the sand well-decomposed manure ; and when the plants are planted, a stick in proportion to the plant should be put with it, and at least eighteen inches in the ground, and not less than two inches in diameter, to which they must be care- fully tied as they grow, never allowing more than one stem tc each plant; and the side branches should be cut off from one to three feet from the ground, according to the height of the plant. Lmperor de Maroc, the most favourite crimson Dahlia, tipped with white, comes invariably true to its cha- racter in sandy soil, whereas, in rich, heavy soil, it is fre- quently only crimson The worst of all soils for the Dahlia is a rich loam, retentive of moisture; in such they grow to wood and foliage, producing few and very imperfect flowers. The best disposition or arrangement in planting the 104 ARRANGEMENT. "May Dahlia, I think, is in groups; each group should be com- posed of a different section of colour: this affords a close comparison, and gives greater diversity of landscape than combining the colours; the tallest-growing sorts should be carefully planted in the centre or at the back of each group. The roots should be planted from three to four feet from each other every way. But where they are planted in rows along walks or avenues, two or three feet will be a sufficient distance from plant to plant. Individual plants look ex- tremely well if they are of a dwarf habit. To have a con- tinued succession of bloom, there should be two plantings ; the first about the fifteenth of the month, and the latest about the end of June; it is the June planting that gene- rally produces the finest flowers; this fact (though lately discovered) is now well understood by some cultivators, and is easily accounted for. When plants are forced and planted early, they are in a flowering state much earlier, to be sure, but they are overtaken with, perhaps, a hot dry summer, which “blights” the buds, and are more subject to the dis- ease called ‘‘curl;” the young leaves, as they expand, are per- forated with numerous holes ; the margins become brownish, as if burnt; they then become curled, placid, and the whole plant unhealthy and dwarfish. The principal stem ceases to grow, and numerous suckers and stems arise from below, forming a dense bush. The flowers of such plant, as might be expected, are small and irregular ; and however excellent the variety may be, they yield nothing but disappointment to the anxiously expectant cultivator. This disease is causcu by an insect, Cymix Chloroterus, or green bug. It inhabits the extremities of the Dahlia, and grows and feeds on the under surface of the young leaves, and in its destruction is aided by our frequently hot and arid months of July and August. Hence, the reason that the late planting gives most satisfaction, they are in these months in a rapid grow- ing state, and if attacked outgrow the effects, and push at once into bloom in the more moist and cooling month of September. The only remedy that is known for the above evil is, to look over the plants cautiously in the morning, when the first attacks are perceptible, and pick off the in- sects; it has to be approached with caution, as it instinctively throws itself down among the leaves if disturbed; and if it escapes it again climbs up, and commences its depredations May.] ARRANGEMENT. 105 It is admitted that there are exceeding one thousaud distinct named varieties now in cultivation, and it may be desirable to some that a select list of the choicest named sorts now in cultivation should be given: but such is the almost endless multiplicity of kinds, and such the numerous additions every year made, that in a few years those I may mention now as being fine will then most probably be considered wholly useless.

The above are the choicest in cultivation at the present time, and for farther description in regard to colour, height, and price, we beg to refer our readers to the periodical cata- logues of our respectable nurserymen that are issued every spring, and contain many other sorts of eminence; and not a few equally desirable with the above, though the descrip- tions of some that are annually received from England are more tempting than the article. Whether there are some sorts that do produce more perfect and beautiful flowers in their humid climate than they do wien transferred to ours, we cannot practically decide, but presume that it is the fact, for we are confident, and every season does more fully con- firm it, that the seedlings grown in this country from seed . sowed here do grow better, and flower finer, than the gene- rality of those imported ; and, to prevent us adopting inferior sorts, and giving them dashing names, we subjoin the follow- ing rules for judging :— CHARACTER OF A FINE DAHLIA. “The best judges distinguish Dahlias by the three criteria of form, colour, and size. “1. Form.—The front view of the blossom should be perfectly circular, without notches or inequalities, caus.d by the petals being pointed, and not, as they should be, rounded ; smooth at the ¢lges, and slightly concave, but not so much 108 ANNUALS, HARDY AND TENDER [ May. us to show any of the back. One of the most perfect flowers, in this respect, is the Springfield Rival. When the petals are pointed, notched, fringed, piped, quilled, concave, convex, or flat, the perfectness of the circle is broken, and one indispensable beauty in the eye of the florist is deficient. “When the eye or disk is shown in the full-blown flower, it is also a striking defect. “The side view of a first-rate flower should be that of a perfect hemisphere. ‘“‘ There is, perhaps, no example of this perfection of form witheut some slight deficiency. The Countess of Liverpool is one of the nearest to a perfect flower in this respect. “2. Colour.—-This is looked upon by florists as an inferior consideration to form, though it is usually the first to attract the notice of common observers. “Tn flowers of one colour, or selfs, the colour ought to be bright and distinct, without any breaking or blotching. When there are stripes, mottlings, shadings, or edgings, these should be clear and uniformly marked, the colours dis- tinct without clouding or running. “3. Size—Although large flowers with superior form and clear distinct colours are esteemed superior to small flowers with the same properties, yet size alone is looked upon by florists as nothing when form and colour are defec- tive.” Particular care should be taken with seeds, especially such as are saved from fine sorts. If they are sown, about the first of April, on a gentle hot-bed, or in a green-house in plots, filled with light rich earth, cover the seeds about three-cighths of an inch, and when they have made leaves, pot them off singly into small pots, till time for planting out, or where a quantity is grown, three plants may be put into one pot, and thus planted, and when they bloom the bad can be pulled up, leaving those of good character to stand for farther trial; none should be kept but such as come up to the above rules; and if they do not do so the first year, there is little hope of their being more perfect the second. ANNUALS, HARDY AND TENDER. By the first of the month, finish sowing all hardy Annuals and Biennials ; aud about the middle of the month all those May. | ANEMONES AND RANUNCULUS. 1u9 that are tropical. The weather being now warm, they will vegetate in a few days or weeks. Attend to thinning of those that are too thick, giving gentle watering to such as are weak in dry weather. Those that have been protected in frames should be fully exposed therein night and day; take the first opportunity of damp cloudy days to have them trans- planted into the borders or beds, lifting them out of the frame with as much earth as will adhere to their roots. CARE OF HYACINTHS, TULIPS, ETC. For the treatment of these, while in bloom, see last month. The best time to take them out of the ground is about five weeks after they are done flowering, or when the stem ap- pears what may be termed half-decayed. The best method to dry them is to place the roots in rows, with bulb to bulb, the stems lying north and south, or east and west. Give the bulbs a very thin covering of earth, merely to exclude the sun, so that they may not dry too rapidly, being thereby liable to become soft. When they have thoroughly dried in this situation, which will be in eight or ten days in dry weather (and if it rains, cover them with boards), take them to an airy dry loft or shade, clearing off the fibres or stems, and in a few weeks put them in close drawers, or cover them with sand perfectly dry, until the time of planting, for whicn see October. It is not advisable to allow any of the bulbs of either Hyacinths or Tulips to seed, as it retards their ripening and weakens the roots, except where there are a few desired for new varicties. The small off-sets must be carefully kept in dry sand, or immediately planted. ANEMONES AND RANUNCULUS. These, while in bloom, should be carefully shaded from the sun by hoops and thin canvass, or an erect temporary awning; and as soon as they are done flowering, “hey must be fully expences ans the waterings given up. 110 DOUBLE WALL-FLOWERS. [ May TUBEROSES AND AMARYLLIS, That are not planted, should now be done. For full di- rections, see last month. In many seasons, any time be- fore the twelfth is quite soon enough; but nothing ought to be delayed when the season will permit it to be done. It is necessary to have them properly labelled. AURICULAS, POLYANTHUS, AND PRIMROSES Will now be done flowering, but still must be carefully kept in a cool, shady situation, and all decayed leaves cut off as soon as they appear. Examine them carefully and frequently, in case slugs of any description be preying upon them. A dusting of hot lime will kill them, or they may be otherwise destroyed. Some have recommended to repot and slip those plants when done flowering, “ or they will contract a destructive disease ;”’ which disease is a loss of verdure, ana is induced by too much heat and drought, and a few other causes from inattention; but if attended to as above, until September, when they should be fresh potted, they will have time to be sufficiently established before winter, which is the most judicious time to take off slips, for two reasons, namely, they do not want so much nursing through the most preca- rious season of the year (summer) for these plants, and they begin to grow, and will root afresh sooner. DOUBLE WALL-FLOWERS. As these are very seldom grown from seed, and are semi- biennials, art has to be used to preserve or renew them. About the end of this month, take shoots of this year about three inches long, cutting them carefully off, and smoothing the cut end with a sharp knife: from this, cut the lower leaves off about one inch and a half, and then put it in the ground; choose a very shady spot, mixing the soil with a little sand and earth, or decayed leaves. Sprinkle them three times a day until they have taken root, which will be in a few weeks. Keep the cuttings about four inches apart. June, July.] AUTUMN FLOWERING BULBS. Ie GENERAL OBSERVATIONS. We do not consider that it is essential every month to re- peat the necessity of tying uy plants, cutting down weeds, raking, &c., with many other similar observations. We have already been full on these su jects, and expect these to be remembered through the seasen. Particular care, however, is required to carnations, pinks, or any plants that have heavy heads and slender stems. If carnations are desired to flower strongly, cut off all the buds except three, leaving the upper- most and any other two of the largest. All climbing plants should have timely support, and tied securely every week while they are growing. JUNE AND JULY. HOLLAND BULBS. THE lifting of these will be general in June. For direc- tions, see May. It is not advisable to take up Jonquils, Fritillaria, Crocus, and Iris. oftener than every alternate year. Jonquils may stand three years. Anemones and Ranunculus should be carefully lifted after their leaves begin to fade. Do not expose them to the sun, but cover slightly with earth or sand until thev are perfectly dry, when they may be sifted out of the earth, and put into drawers carefully labelled. Some recommend to soak these roots in soap-suds, to destroy a worm with which they are frequently attacked. We know not how far this may be carried, nor the good or bad effects, never having practised it. AUTUMN FLOWERING BULBS. These are Amaryllis litea, now called Sternbérgia litea ; A, Belladénna, now Belladénna purpurascens; Crocus satt- vur, C. Pallasii C. serotinus, and C. nudiflorus and all the 112 CARNATIONS AND PINKS. [June, July. species of Célchicum, with species of several other genera not introduced into the country. They should all be lifted as soon as the foliage is decayed, and kept only a few weeks out of the ground, and then again replanted in fresh soil. The economy of the genus Cdlchicum in regard to its bulbs, flowers, and seeds, is altogether singular, and may be termed an anomaly of nature. In producing the new bulbs or off- sets, In a very curious manner the old one perishes. The flowers, which arise with long slender tubes from the root, die off in October, without leaving any external appearance of seeds. These lie buried all the winter within the bulb; in spring they throw up a fruit-stalk, and are ripe about the first of June. How beautiful and admirable is this provision! The plant blooming so late in the year would not have time to mature its seeds before winter; and is, therefore, so con- trived that it may be performed out of the reach of the usual effects of frost, and they are brought above the surface when perfected, and at a proper season for sowing. CARNATIONS ANT PUNKS. In order to make the former flower well, if the weather 1s dry, give them frequent waterings at the root, and tie them up neatly to their rods. The criterion of a fine Carnation is—The stem strong and straight, from thirty to forty inches high; the corolla three inches in diameter, consisting of large, round, well-formed petals, but not so many as to crowd it, nor so few as to make it appear thin or empty; the out- side petals should rise above the calyx about half an inch, and then turn off in a horizontal direction, to support the interior petals, they forming nearly a hemispherical corolla. The interior petals should decrease in size toward the centre, all regularly disposed on every side ; they should have a small degree of concavity at the lamina or broad end, the edges perfectly entire. The calyx above one inch in length, with strong broad points in a close and circular body. The colours must be perfectly distinct, disposed in regular long stripes, broadest at the edge of the lamina, and gradually becoming narrower as they approach the unguis or base of the petal, there terminating in a fine point. Those that contain two colours upon a white ground are esteemed the finest. June, July.] LAYING CARNATIONS AND PINKS. 11s The criterion of a double pink.—The stem about twelve inches, the calyx smaller, but similar to a carnaticn; the flower two inches and a half in diameter; petals rose edges; colour white and pure purple, or rich crimson; the nearer it approaches to black the more is it esteemed; proportions equal as in carnation. Those that are very tasteful with these flowers are attentive to the manner of their opening. Where the calyx is deficient in regular expansion, to display the petals; that is, where there is a tendency to burst open on one side more than on the other, the opposite side in two or three different indentations should be slit a little, at several times, witk the point of a small sharp knife, taking care not to cut the petals, and about the centre of the calyx tie a thread three or four times round to prevent any further irregularity. Some florists and connoisseurs place cards on them. This is done when the calyx is small. Take a piece of thin pasteboard, about the size of a dollar, cut a small aperture in its centre to admit the bud to pass through. When on, tie it tight to the rod, to prevent the wind from blowing it about; and when the flower is expanded, draw up the card to about the middle of the calyx, and spread the petals one over the other regularly upon it. When these plants are in flower, their beauty may be prolonged by giving them a little shade from the mid-day sun by an awning of any simple description. Where they are in pots, they can be removed to a cool shady situation (but not directly under trees). OF LAYING CARNATIONS AND PINKS. This is a necessary and yearly operation to keep a supply of plants, and likewise to have them always in perfection. As the process of laying, though simple, may not be known to all who are desirous of cultivating these plants, we will give an outline of the mode of operation. Provide first a quantity of small hooked twigs (pieces of Asparagus stems are very suitable), about three inches long, for pegging the layers down in the earth. Select the outward, strongest and lowest shoots that are round the plant; trim off a few of the under leaves, and shorten the top ones even with the knife, and then applying it at a joint about the middle of the under 10* 114 OF BUDDING, ETC. [June, July. side of the shoot, cut about half through in a slanting diree- tion, making an upward slit toward the next joint, near an inch in extent; and loosening the earth, make a small oblong cavity one or two inches deep, putting a little fresh light earth therein. Lay the stem pirt where the slit is made into the earth, keeping the cut part open, and the head of the layer upright one or two inches out of the earth; and in that position peg down the layer with one of the hooked twigs, and cover the inserted part to the depth of one inch with some of the fresh earth, pressing it gently down. In this manner proceed to lay all the proper shoots of each plant. Keep the earth a little full around the plant, to retain longer the water that may be applied. Give imme- diately a moderate watering, with a rose watering-pot, and in dry weather give light waterings every evening. Choose a cloudy day for the above operation. In about two months they will be well rooted. OF BUDDING OR INOCULATION OF ROSES. According to what we have previously hinted in regard to having roses as standards, where such are desired, the month of July or August is a proper time for the operation of budding. The kinds to be taken for stocks should be of a strong, free growth; such as Manitta, Maiden’s blush, R. canina, and frequently the French Eglantine are taken. Be provided with a proper budding-knife, which has a sharp, thin blade, adapted to prepare the bud, with a tapering ivory haft, made thin at the end, for raising the bark of the stock. Yor tyings, use bass strings from Russian mats, which should be soaked in water to make them more pliable. The height of the stock or stem at which the bud is to be inserted, is to be determined by the intended destination of the tree (as it may be properly called). Choose a smooth part of the stem, from one to three years old. Having marked the place, prune away all the lateral shoots about and underneath it. With the knife directed horizontally, make an incision about half ar inch long in the bark of the stock, cutting to the wood, but not deeper; then applying the point of the knife to the middle of this line, make a perpendicular incision under the first, extending from it between one and two inches. June, July. | OF BUDDING, ETC. 115 Having a healthy shoot of the growth of this year provided of the kind that is desired, begin at the lower end of this shoot, cut away all the leaves, leaving the footstalk of each. Being fixed on a promising bud, insert the knife about half an inch above the eye, slanting it downward, and about half through the shoot. Draw it out about an inch below the eye, so as to bring away the bud unimpaired with the bark, and part of the wood adhering to it; the wood now must be carefully detached from the bark. To do this, insert the point of the knife between the bark and wood at one end, and, holding the bark tenderly, strip off the woody part, which will readily part from the bark, if the shoot from which the piece is taken has been properly imbued with sap.* Look at the inner rind of the separated bark, to see if that be entire; if there be a hole in it the eye of the bud has been pulled away with the wood, rendering the bud use- less, which throw away; if there be no hole, return to the stock, and with the haft of the knife gently raise the bark on each side of the perpendicular incision, opening the lips wide enough to admit the prepared slip with the eye. If the slip is longer than the upright incision in the stock, reduce the largest end. Stock and bud being ready, keep the latter in its natural position; introduce it between the bark and wood of the stock, pushing it gently downward until it reaches the bottom of the perpendicular incision. Let the eye of the bud project through the centre of the lips; lay the slip with the bud as smooth as possible, and press down the raised bark of the stock. ‘he bud being deposited, bind that part of the stock moderately tight with bass, beginning a little below the incision, proceeding upward so as to keep the eye uncovered, finishing above the incision. In a month after the operation, examine whether the bud has unitea with the stock. If it has succeeded, the bud will be full and fresh; if not, it will be brown and contracted. When it has taken, untie the bandage, that the bud may swell, and in a few days afterwards cut the head of the stock off about * We once budded three eyes of the white moss rose, after they had, by mistake, been carried in the pocket of a coat three days. "he shoot was soaked six hours in water, and two of the buds grew. From this we infer that shoots, if properly wrapped up, may be carried very great distances, and grow successfully. 116 EVERGREEN HEDGES. [August six inches above the inoculation, and prevent all shoots from growing by pinching them off. This will forward the bua, which will push and ripen wood this season; but it must be carefully tied, as it grows, to the remaining head of the stoci.. Some do not head down the stock until the following spring, thereby not encouraging the bud to grow, which, if winter sets in early, is the safest method. OF WATERING. If the season be dry, look over the lately planted shrubs. and give them frequent copious waterings; and a few of the finest annuals that are wanted to flower perfectly should be attended to. We do confess that we used to be advocates for giving plenty of water to the Dahlia, but the severe drought of 1838 put our science to the test, and the result was, that of about one hundred plants of our most choico kinds, which we regularly watered three times a week, for nine weeks, during which period we had not a drop of rain the plants grew luxuriantly, but many of them never pro- duced a perfect bloom; and those that had no attention whatever paid to them, except a little manure or litter Jaic on the surface over the roots, flowered almost as well as in our more moist seasons. Hence we infer that an occasional water- ing may be of service, but continued and repeated artificias waterings are injurious. AUGUST. EVERGREEN HEDGES. THESE always make two growths in the season, and ths: best time to perform the operation of clipping or dressing them is before the plants begin their second growth. Choose. if possible, dull and cloudy days, as in such weather they will not be so liable to get brown or bruised by shearing The general practice in forming these is to have the sides August. | BULBOUS ROOTS. 117 even and the top level, forming a right angle on each side. However neat in appearance this may be considered, it certainly is stiff and formal. We never approve of clipping where it can be avoided, and, when adopted, nature ought to be imitated. Therefore, have all hedges and edgings tapering toward the top. CARNATIONS AND PINKS, If laid about the end of June, and have been properly attended, will, by the end of this month, be well rotted and fit for transplanting. Clear away the earth lightly, and cut them clean off from the parent plant, nearer the stool than the original slit. Raise them neatly out of the earth, with as many of the root-fibres as possible; cut off the naked part of the stem close to the fibrous coots, and trim away the straggling leaves. Plant the finest sorts in four-inch pots, and those more common, three plants in five-inch pots, in the form of a triangle, which can be separated in spring to plant in the garden. Any of the principal stools should be (if in the ground) lifted and put into seven-inch pots to be preserved : the others may be allowed to stand through the winter, cover- ing them with a few dry leaves. Keep them in the shade a few weeks, when they may be fully exposed. Give gentle and frequent sprinklings of water until they have taken fresh root ; or, if in want of pots, mark out a bed that can be covered with a frame, preparing the soil therein properly. Plant them from four to six inches apart. Shade them from the sun until they begin to grow, giving sprinklings of water over the foliage every evening. BULBOUS ROOTS. Look over the bulbs that are out of the ground, and exa- mine those that require planting. Of Fritillaria there are about twenty species, but few of them generally cultivated, except F’. imperialis, Crown Imperial, and F. pérsica. Of the former there are many very splendid varieties, such as Crown upon crown, Lutea Maxima, Striped leaved, Double flowered, &c. These will require planting, and ought not to 118 DAHLIAS. ; September be lifted oftener than every third year. They require a deep, rich, loamy soil, and, if in beds, plant them from five to seven inches deep, and ose foot apart. They will grow under the shade of trees, or in any situation where the soil is adapted for them. No imbricated or scaly bulb ought to be retained long out of the ground. When any of these are lifted, and the young bulbs taken off, they should be planted at once. See particularly, on bulbous roots in general, next month. SOWING SEEDS )F BULBOUS ROOTS. Where any seeds of these are saved, with the intention of sowing, let it be done this month. Procure boxes about seven inches deep, and, in size, proportioned to the quantity to be sown. Put five inches of light, sandy soil in the box, level it smoothly, and sow the seeds separately and thickly ; cover with half an inch of light sandy loam, with a portion of earth from the woods. Keep the box or boxes im a shel- tered situation, giving frequent sprinklings of water, to keep the earth damp, which must be protected with a frame, or covered with leaves during winter. The plants will appear in the spring, and must be watered and kept in the shade. When the leaves decay in June, put one inch more soil upon them, and the second year they can be planted with the small off-sets in the garden, and treated as other bulbs. They must be carefully marked every year. Tulips require several years of trial before their qualities are known ; and a poor soil is best suited to produce their characters after the first bloom.

Strictly observe their respective heights and colours, that they may be duly disposed and interspersed next year, if not done so this, Attend particularly to the merits of those grown from seed. GENERAL CARE OF PLANTS IN POTS. All the flowers that are in pots, and intended to be kept in frames during winter, should have a top-dressing and a gene- ral preparation for their winter quarters, by tying up, Kc. The carnation and pink layers that were lifted and potted last month must be brought from the shade as soon as they begin to grow; and those that are not lifted, have them done forthwith, that they may be rooted afresh before the frost sets in. All Wall-flowers and Stocks should be lifted about the end of this month, and planted in five to seven-inch pots, and treated as directed for carnation layers last month until they begin to grow, when they must be fully exposed. PREPARING BEDS AND BORDERS FOR BULBOUS ROOTS. Bulbous roots of every character delight in deep free soil ; consequently, wherever they are desired to be planted, duu attention must be paid to put the soil in proper order, to have them in perfection. Where there is a quantity in- tended to be planted, to have them in beds is the genera: and preferable method. These ought to be dug from eight- een inches to two feet deep, at the bottom of which place three or four inches of decayed manure. Where the soil is poor, it should be enriched with well-decomposed manure and earth from the woods, incorporating both well with the soil, breaking it all fine. This being done, allow it to stand until the middle of next month, which see for farther directions. GENERAL OBSERVATIONS. Lie up carefully all the Chrysdnthemums, Tuberoses, &e.

SOWING AND SAVING SEEDS. . About the end of this month or beginning of next is an advisable period to sow seed of Delphiniwm Ajdcis flore pléno, or Double Rocket Larkspur. This plant does not flower in perfection unless sown in autumn, and grown a little above ground before winter ; when a few leaves can be lightly thrown among them, but not to cover them entirely, or a few branches thickly laid on will answer as well. There are several other annuals that bloom more early and much finer by being sown about this period; such as Lrysimum, Gilia, Coredpsis, Centauréa, Clarkia, Collinsia, &e. Be attentive in collecting and saving all kinds of seeds, and have them correctly named, with the year in which they were rown. The finer kinds of Pansy seeds that may have been collect- ed during the season, should now be sown in a rich, free, loamy soil, and in a situation where they can be covered dur- ing winter with a temporary frame of boards; although they are perfectly hardy, yet they will bloom earlier and more euperb in the spring by having a slight protection OCTOBER. OF PLANTING VARIOUS BULBOUS AND TUBEROUS ROOTS. From the first of October to the middle of November is she best period for a general planting of bulbs, corms, and ubers, which, if the ground has been prepared, as formerly directed, will now be in readiness. We will give the names and descriptions of a few of the leading sorts. Anemone horténsis.—The cultivation of this tuber has been attended with less satisfaction than any other floral plant that has been introduced into this country. The gene- October. | CROCUS—HYACINTHS. 121 ral failure may, in part, be attributed to the very inferior roots annually sent from Holland, which rarely arrive in good order; and those that do grow are very discouraging, never making a tuber sufficient for another year’s planting. Several hundred varieties are cultivated in England with great care and complete success. ‘They are planted in a deep rich soil, using a considerable portion of cow manure and decom- posed leaves, covering the crowns of the roots about two inches. The tubes are flat, but the eye from whence the flower-stem arises is apparent on one of the sides, which must be laid uppermost. During the severity of winter they should be protected by a frame, and have a sprinkling of very dry leaves strewn among them. Crocus.—There are upwards cf one hundred varieties of this vernal flower in cultivation, attended with universal suc- cess. They delight in rich soils, and may either be planted in beds or rows, at least two inches deep, and six inches from row to row—they seldom require removal; every three or four years will be sufficient. They can be purchased at from seventy-five cents to two dollars per hundred, according to quality. When they are done blooming, the foliage should not be removed till perfectly decayed. ; Fritilldria, or Crown Imperial. See last month. Hyacinths.—The ground that was prepared for these last month should all be divided into beds four feet wide, leaving between each alleys of twenty inches. Skim off four or five inches of the surface of the former into the latter, level the bed smoothly with the rake, and mark it off in rows eight inches apart. Plant the roots in the row eight inches asunder. Thus they will be in squares, and by planting the different colours, alternately, the bed will be beautifully diversified. Cover each bulb with sand, when it can be procured. Put about four inches of earth over the crowns, which will make the beds from two to three inches higher than the alleys. The beds before and after planting should be gently rounded from the middle to each side, to let the rain pass off. Finish all by raking evenly, straighten the edgings with the line, and clear out the alleys or pathways. We have grown Hyacinths in great perfection, when, in addition to the above, we covered them with two to three inches of cow manure. The Dutch florists name nearly two thousand varieties of this flower, and have large fields de- voted to their culture When the double varieties were first 1] 122 PONIAS. [ Octob.2 brought into notice, they sold at from one to two thousand guilders a root (about from four to eight hundred dollars). The finer kinds ean be purchased at from two to four dollars per dozen. Iris, or Fleur de luce-—The English and Parisian Irises are coming into repute as showy garden-flowers. They will grow in any well-prepared soil, and require to be planted in the same manner as the tulip. Jonguils.—Double and single. Plant these in the same soil as 7'ulips, six inches apart, and cover three inches deep. They do not flower so well the first year as in the second and third, therefore should only be lifted every third year. \— Lilium.—tThe family of Lilies are all splendid, very inte- resting, and easy of culture, requiring merely a good deep loamy soil—nowise inclined to moisture. They are all hardy, except L. japonicum and L. longiflorum, which we lift in November, and again plant them about the first of March, keeping them through the winter in dry sand, in a cellar free from frost. The hardy kinds, deserving most attention, are L. Candidwm (the double variety of it is not worth growing), L. Chalceddénicum and its varieties, L. Ti- grinum, L. Céncolor, and L. Martagon ; these, with the species indigenous to this country, are all very beautiful. They should be planted from three to five inches deep, accord- ing to the size of the bulb, and need not be taken up oftener than once in every three or four years. None of the species ean be transplanted after they have grown, without injuring their flowering. Narcissus require treatment similar to the Lily, except the soil, which must be richer, and even then they do not bloom so finely in a few years as they do when first imported ; but they are cheap, and can annually be procured. Peonias are all magnificent in flower, and, for display, are not surpassed by any spring-blooming plant ; and we do cheer- fully urge our readers to cultivate the choiee sorts, which can scarcely be said to have a rival. Such are— P. Moutén Bénksii, common double blush tree Paonia. P. Moutén papaveracea, single white tree Pzeonia, with pur: ple centre. P. Moutdén rosea, large rose, semi-double tree Paonia LT’. Moutdén odordta, sweet-scented, rose-coloured tree Feeonia. P. Moutdéa albida pleno, double white tree Paonia.

There are also a few very choice single kinds that are desira- ble for growing to raise new sorts from; for it is from the single species that the Chinese have been so successful in procuring the magnificent double varieties, which are so anx- iously and perseveringly sought for. The seeds mature well in this country, and should be sown as soon as ripe; they will vegetate the following spring, and in three years may be expected to bloom. The Peony will grow in any rich, loamy soil, which should be at least fifteen inches deep. An eastern situation or aspect is best adapted for them in this ,atitude ; but in the more Southern States, they will display their flowers better on a northern aspect, or where they will be shaded from the sun, but not under the dripping of trees. The most suitable time for planting them is in September, ctober, or November. Spring-planted roots never succeed well the first year. Pzeony moutan and its varieties are all of a shrubby nature, and will grow into large bushes, pro- ducing from fifty to one hundred blooms of not less than fifteen inches in circumference ; they can be propagated by division of the root, or by layers. Lulips.—As this flower will soon be a decided favourite over this mighty country, we will give a minute description of the soil most genial to it, at the same time remarking that it will grow in almost any soil or situation, though less per- fect. Many of the kinds are of the most splendid colours and {24 ™ELEPS. { October strong in growth, frequent'y growing over three feet in height, with cups sutiicientiv large to satisfy the greatest Bacchus. All writers agree that Tulip beds should be ‘“‘four feet wide ;” though I think three and a half will be found more convenient, and, in length, according to the number of roots to be planted. The soil should consist of good fresh loam, mixed with a small portion of well-rotted stable-manure, at least two years old. The whole should be incorporated together four months previous to using. The common soil should be taken owt sixteen inches deep, and filled with the above compost. Raise the beds not less than three inches above the paths at the outside, and about six or eight inches in the middle: this convexity will assist in throwing off the water in times of heavy and continued rains. The bed thus formed, plant the bulbs in rows, lengthwise on the bed, about six inches from bulb to bulb, and seven inches from row to row. The beau may be marked out by straining a line very tight, lengthwise on the bed, and beating it with the back of the spade, leaving a lined groove along the ground. Then, with a lath four feet long, let the bed be marked across at six inches distance, so as to leave distinct impressions at each crossing of the ground-1ines; for these will form tue spots where the bulbs are to ve planted, by means of a dibber, made larger than the largest bulb, and flattened at the end. The holes are to be made tour inckes deep, and about half an inch of sharp sand ought to pe dropped in each. The centre line ought to be planted witn the tallest kinds, and the out- side of the bed with the lowest. In severe frosts they should be protected by boards or branches. Tulips have ever been held in the highest estimation. As early as 1637 history records one hundred and twenty Tulips being sold at public auction for no less a sum than nine thousand guilders, equal to thirty-six hundred dollars; and in England, at the present day, a good collection is valued at five thousand dollars. Florists generally divide them into tnree classes, viz., first, Bybloemens, such as have a white ground, variegated with purple, as Bienfait, or Washington, &c.; secondly, Bizarres, having a yellow ground variegated with scarlet, purple, rose, or velvet, as Trafalgar, Duc de Savoie, &e.; and, thirdly, Roses with white ground, variegated with rose, scarlet, or erimson, as La Tendresse, Rose mignonne, &e a October. | GRASS AND GRAVEL-WALKS. 125 The superb kinds are often very expensive; even fifty pounds sterling is frequently given for a single bulb; and we doubt much if these high-priced kinds are finer than Washing. ton, Milo, or Trafalgar, which, with many others, can be pro- eured for less than one dollar each. PLANTING AND TRANSPLANTING. This is a very proper period to plant the beautiful and early flowering Pyrus japénica, now called Cydonia japo- nica. The blossoms are of a rich searlet colour. It is the earliest fowering shrub of the garden, and deciduous, though said by some to be “an evergreen.’ The plant is bushy, and well adapted for single plants in grass-plats, or forming low ornamental hedges. ‘There is likewise CO. 7. dlba, a fine blush variety of the same habit, and both are of the hardiest nature. Double Primroses, Polyanthus, Daisies, &.—Any of these that were planted in shaded situations in spring, and have been preserved through the summer, should have for their farther protection a bed well sheltered from the north-west, in which they should be planted four inches apart. Give them a few sprinklings of water in the morning, and have a tempo- rary frame of rough boards put together to place over them during the severity of winter. The frame may be covered with the same in place of glass, which must be kept over them while they are in a frozen state. Any other plants that are in the ground, which are intended to be protected with frames through the winter, ought to be immediately lifted and potted, and treated as directed for all new-potted plants. GRASS AND GRAVEL-WALKS. The former should be trimly cut and well rolled this month, that they may appear neat all winter.. Never allow decayed leaves to lie any time upon them, as they are apt to rot out the grass. The latter should be divested of every weed, and receive a firm rolling. Olear them at all times of leaves and other litter.. These, if on a declivity, and have 1 Be 126 DAHLIAS.

If it is not thus irrit it adheres so closely to the foliage that it will keep you at de- fiance. The under or dark side of the leaves is its residence ; and we have observed a plant in a house where there was only light on one side, with the dark side literally covered, while the light side was elean. So much for having houses with plenty of light. The effects of this insect are of a corroding nature, extracting all the juice from the leaf; and where they have got to the extremity, the foliage is completely yellow. and of a decayed appearance. Cocus , or turtle insect. We have never ob. served this insect arrive to any extent. It is the largest of any known among us, and very like a turtle in miniature. On lifting it from the wood, to which it generally adheres, there appear to be hundreds of eggs under it, but fumigating completely destroys the larvae. In our opinion, this turtle in- sect is no other than the old female of the brown scaly insect, which swells to a large size before depositing its eggs. We have frequently observed the insect dead in this enlarged state, and question if this be not the last stage of its transmi- gration. The male insect is winged, and very active in its movements. Where bulbous roots, such as Hyacinths, Jonquils, vias, Lachenallas, &c., are required to be early in flower, they may, during this month, be put in the front of the hot-house and watered freely till they bloom, when they may be taken to the green-house or parlour. Azaleas, Rhododendron Roses, and some other plants, do admirably to force; and where there is a large stock, a few should be h sught into early bloom with the heat of this de partment. OF CLEANSING PLANTS, HOUSE, ETC. This subject ought to be kept constantly in view. How- ever correctly everything else may be executed, without that adorning beauty, cleanliness, all will appear only half done. Therefore let all the dead leaves be picked off every day, the dust and other litter swept out of the house, and, when necessary, the house washed, which will be at leas! 144 HOT-HOUSE. [ February. once a week. ‘That the foliage of the plants may always appear fresh, syringe them every morning, when there is the appearance of sun. At present, this will in a great measure keep down the insects, and will prove a bane to the red spider. Tie up neatly with stakes and threads of Russia mat all the straggling growing plants; let the stakes be proportion- ate to the plants, and never longer, except they are climbing sorts. Do not tie the branches in bundles, but singly and neatly, imitating nature as much as possible. If any of the plants are affected with the Cocus insect, let them be cleansed according to the plan already mentioned, taking particular care also in washing the stakes to which they had been pre- viously tied, and burning all the old tyings, which contain the larvee of the insect in many instances, especially of Cocus hesperidus. It is premised, when any of these things are done, that they will be well done, and not half doing, and always doing. Cleanliness, in every respect, promotes a pure air, which is congenial to vegetation, and will, with other attentions, always assume a healthful and vigorous appearance in the house. FERRUARY In the early part of this month, the weather generally is very cold and changeable in the Middle States, and strict attention, with the greatest caution, will require to be paid to the management of the hot-house. Most of the tropical plants commence an active state of vegetation; and, if checked by temperature or otherwise, they will not recover until midsummer. The thermometer may be kept two or three degrees higher with fire heat than last month: the sun will be more powerful, and this will, in a great degree, in- crease the vigour of the plants. Air may be admitted when the thermometer rises to 75° or 80°, not allowing it to rise higher than the latter. In giving air, let it be done by the top sashes. It is improper to give it in any way to cause a vurrent, for the external air is yet very cold, although the february.] | HOT-HOUSE—OF INSECTS, ETC. 145 sun is more powerful. An inch or two on a tew of the sashes, as has been previously observed, will be effectual in keeping the temperature low enough. With regard to firing, what was said last month may suffice for this. Always recollect that it is more preferable to keep out the cold than to put it out. It will frequently happen in the time of intense frost that the weather is dull. In such cases, fire in a small degree is requisite ali day. Heavy snows ought never to be allowed to remain on the shutters while they are on the house. If the snow lies on the sashes one day, the internal heat will dissolve some of it; night coming on, will freeze it to the wood-work, when it will become a solid mass, and frequently cannot be separated with- out much damage. If allowed to remain on for two days, the plants are very much weakened and the foliage discoloured. Therefore, let the snow be cleared off instantly, that no incon- venience may take place. It will be observed that plants absorb more water this month than last. The quantity given will require to be increased, according to the increase of vegetation and the advancement of the season; but never give it until the soil begins to dry, and then in such proportion as will reach the bottom of the pot. The best time to water is after the sun has got on the house in the morning, observing all the directions given in January. - OF INSEOTS, ETC. Perhaps sufficient observations were given under this head last month; but the importance of keeping the disagreeable visiters out of the house constrains us to make a few more . remarks. Man cannot be too frequently guarded against his foes, more especially when they are summoning all their forces, and no profession has more than that of the Horticulturist. Let a strict examination be made about the end of the month for the red spider ; they will be in operation some wecks before their depredations are observed on the foliage. The under side of the leaf is their resort in the first instance, and on such lants as have been already mentioned. Observe daily the young shoots, in case the green fly be- 13 146 HOT-HOUSE—OF REPOTTING PLANTS. [[eorwiry. comes numerous. They give the foliage a very disagreeable appearance, and it is too often intolerable, before their career is arrested. It also takes a stronger fumigation, which has fre- quently to be repeated the following day to the same degree much to the injury of many of the plants, and adding to the disagreeableness of the continued vapour in the house. OF REPOTTING PLANTS. About the end of the month, some of the plants of Cur- cima Amémum Kempféria, Alpina, Phrynium, Canna, Zingiber, Hedychium, and others that are on the dry shelf, will be offering to grow. Let them be taken out of their pots, some of their weakest shoots or tubers taken off, and the strong ones repotted: give gentle waterings until they grow freely, then give in abundance. (Soil No. 17.) Dionea muscipula, or Venus’s fly-trap, grows best in the hot-house, and will, about the end of the month, stand in need of being repotted. This plant is very seldom grown in any degree of perfection, having been always considered a delicate plant in collections. Take it out of the pot just be- fore beginning to grow afresh, and divested of all the soil, leaving only a few of the young roots (it is a bulb, and wil) receive no injury by so doing), put it in new soil; wher potted, place the pot ina saucer with one inch of water in it, giving a fresh supply every other day; this being repeated every year, it will grow, flower, and seed in perfection. (Soil No. 5.) Gesnérias, if in small pots, give larger as they advance in growth. This genus requires to have plenty of pot-room to make them flower well. G. oblongata, G. Zebrina, and G. Sellowii ought to have a situation in every hot-house. They are remarkable for their many brilliant crimson flowers, and continne in flower for a length of time. When the bulbs .egin to push, shake them out of the earth, and repot them nto smaller pots; and, as soon as the roots reach the side of the earth, which will be in about one month, put them in iarger pots, and continue to do so until flowering, which will be about the first of June, observing always to keep the ball of earth entire. G. tubiflora, G. magnifica, G. lutea, and some others, are all well worth attention. (Soil No. 11.) ee February. | HOT-HOUSE—OF CLEANSING, ETC. 147 Gloridsas must be repotted in the beginning of this month; G. supérba is the most beautiful and curious. The crown of the roots ought to be planted one and a half inch deep, taking care not to break them. Do not water much until they begin to grow. The earth must not have much water. As the plants grow, they will require a more liberal supply ; yet it is necessary, at all times, to be moderate in giving it. If well treated, the superb flowers will appear in June or July. (Soil No. 12.) Gloxinias are beautiful herbaceous plants, with large showy flowers, requiring soil and treatment similar to (Gesneria). G. specidsa, dark blue, G. specidsa-pdllida, pale lilac; G. candida, pure white, G. grandifidra, very large light blue, rubra, red; Cerina, pink and white; maxima, lilac and white, Lennigii, rose and white; Maria Van Houttii, white, scarlet throat; Victoria regina, pale blue, white throat; and Teuclerii, rose, white and violet, are the finest, although seve- ral of the other species are very interesting. OF CLEANSING PLANTS, HOUSE, ETC. With regard to cleaning the plants, sprinkling or syring- ing is at all times, to a greater or less degree, necessary. The plants will, in this compartment, be in their first stage of growth, and, if dust or fouiness be permitted to lodge on their foliage, the pores will be obstructed, the plants will be- come unhealthy, and the growth of insects increased. Let all moss, litter, decayed leaves or weeds, be cleared out of the house, the earth in the pots stirred up with a round pointed stick, and fresh earth given where required, that the air may operate therein freely. The house ought always to be sprinkled before being swept, to prevent the dust rising. Attend to the bulbous rocts as directed last month, such as Hyacinths, Narcissus, &c. 148 HOT-HOUSE—OF REPOTTING, ©£TC. [ March MARCH. Ir this department has been regularly attended to, the plants will be in a fresh healthy state. Where there is any sickly appearance, heat has been deficient, or insects of a de- structive character are preying upon the plants. Too much water at the root frequently causes the foliage to become yellow. Regular syringing must be continued in the morn- ing, and it is highly necessary that the water that is used should be of the same temperature as the house; and at all times, whatever water is given to the roots, the same must be observed. For airing, see last month, observing, as the season advances, to increase the quantity. Continue to fumigate when any of the Green-fly appears (see January for directions), and where there are any of the plants infected with the white scaly insect, clean them as there directed. If overlooked for a few months, they will be increased tenfold. Very frequently, where there are only a few, they are neglected until the plant is overrun with them, and then it may be said it is impossible to dislodge them entirely. Clear off all decayed leaves from the plants which will have made fresh shoots, for the decayed leaves very much disfigure the whole collection. We would not have repeated this observation if it was not an essential point, and one which is so frequently neglected. OF REPOTTING PLANTS. Many of the young plants that are growing freely, and where they may be desired to grow to a large size, should be frequently repotted to encourage their growth. Gcsnéria, Gloxinia, and others previously mentioned, must have larger pots, as they require it. Flowering bulbs of Amaryllis may be brought into the heat to make them bloom early ; before they begin to grow, divest them of the old soil, and put them into fresh : this is particularly necessary, when the bulbs are already in large pots. By thus renewing the soil, the pots can be used much smaller: they require plenty of drainage in the pot, and agree best with soil No. 12. April.] HOT-HOUSE—REPOTTING. 149 Where plants of the dwarf Musas are intended to be grown for fruiting, they must have particular attention in repotting as they grow ; about the first of the month will be a proper time to begin : copious waterings are daily required when they are in a growing state. Their soil is No. 12, with one portion more manure. For farther detail, see May. APRIL. WuHeEreE the hot-house has been properly conducted, the plants generally will have a vigorous and healthful aspect. An error frequently arises in the conducting of these depart- ments, by inexperienced operators, being ambitious of out- stripping their competitors. They keep the house in a very high temperature, and admit little or no air. Where such a mode has «been pursued, the plants will have got over their first growth, and the foliage looks yellow and decaying; thus throwing the plants into a state of inactivity, when nature herself commences her most active movements. The tempera- ture should not be under 55° in the night, nor much above 75° during the day, without admitting a little air by the top- lights. It will not do yet to give air by the front sashes, the wind being cool, and a current in the house would be hurtful. The sun is not so powerful, but the heat can be kept down by the air given from above. Hot-house or tropical plants will not materially suffer with 100° of sun heat, provided they are not very near the glass; but such an extreme would be injurious to practise. REPOTTING. Where there is a general assortment of the Cactz tribe, and kept in this department, now is the proper period to give them a general repotting. Of all the tropical floral produc- tions, there is not a family more curious, grotesque, interest~ ing, and beautiful than this; and, what still more enhances their real value, they are in this country of the easiest cul- Te* 150 HOT-HOUSE—OF REPOTTING, ETC. [ May. ture; it is with pleasure that we recommend a few of the grand and the novel, which are faithfully deseribed in the general list given next month. The bottom of every pot must be covered with an inch of pot-shreds, or rough gravel for drainage. MAY. Very few directions for this department remain to be given ; except for shifting plants, aud a few observations on those that are most desirable for the hot-house ; which we will do in this month, considering May and June the best months of the year for that operation. : The days and nights will be very mild by this time, and mie sashes in every favourable day should be opened, both in front and top, so that the plants may be inured to the open air, which they will be exposed to by the end of the month. Leave in the beginning of the month the top sashes a little open every mild night, and gradually, as the heat increases, leave the front sashes and doors open. Continue to syringe them at least every alternate night, and, if possible, every night; and give them all, according to their respective wants, liberal supplies of water every day. Absorption among hot- house plants is as great during this month as in any period of the year. OF REPOTTING PLANTS, ETC. It is our candid opinion that this and next month are the best periods for shifting or repotting all or most of hot-house plants; the end of August being the time always adopted around Philadelphia for that operation (and then they are done indiscriminately). We will assign a few reasons for our practice. First, that it is not congenial to the nature of these plants to have their roots surrounded with fresh soil when they are becoming inactive ; secondly, that there is not a sufficiency May.) HOT-HOUSE—OF REPOTTING, ETC. lol of heat naturally to quicken them to an active state when they are encouraged; and, thirdly, being thus in new soil while dormant, they have a yellow and sickly aspect until they begin to grow; and the foliage, thus deprived of its natural vigour, will not appear so healthful again: whereas, if they are shifted or repotted in this or next month, at which season they are between two stages of growth, they immediately, on receiving fresh assistance, and by the increas- ing heat of the summer, make new growths, are perfectly ripened before the approach of winter, and never lose that vernal appearance they have attained. These are our reasons, acquired from a close practice and observation, and are not influenced by the doings of others which are so much aside. No practical operator especially, nor, in fact, any individual, ought to be governed by custom in regard to the treatment of plants, without having any idea as to why and wherefore, founded on the principles of nature, and governed by her un- erring results. As many are desirous of having a knowledge of plants before they order them, and likewise which are the finest flowerers and their general character, especially those who are at a great distance, and seldom have the privilege of seeing what iv most desirable, our descriptions will be limit- ed, but stil! ill convey some accurate idea of the article described. Acacias --Several of these are desirable in the hot-house for the grandeur of their foliage, beauty of flower, and a few of them as specimens of valuable medicinal plants. A. Housténi, now Annesléia Housténi, is one of the most magnificent of the Mimosa tribe, blooming from August to November in large terminal spikes of a crimson colour, stamens very long and beautiful, leaves bipinnated in pairs. A. grandifiéra, likewise given to Annesléia, and similar to the former in colour, has very large compound bipinnate leaves, with from twenty to forty pairs. A. Catéchu, flowers yellow, wood spiny, leaves bipinnated, about ten pairs. The inner wood of this tree is of a brown colour, from which the Oatéchu used in medicine is prepared. It is disputed whether A. véra or A. ardbica produces the gum Arabic. We are inclined to think it is the latter, which grows prin- cipally on the Atlas mountains. The gum exudes spon- taneously from the bavk of the tree in a soft half fluid state. 152 HOT-HOUSE—OF REPOTTING, ETC. [ May. There are many others of this genus belonging to the hot- house, but being shy in flowering, are not generally esteemed. Most of the flowers have the appearance of yellow balls of down, and are hermaphrodite. The pots should all be well drained. (Soil No. 1.)* Aischynanthus, about tour species, among which &. grandi- florus, 44. Boschianus, dark velyet purple and bright scarlet, and 4. parasiticus are very deserving of culture; they have thick fleshy foliage, are of slender growth, producing orange- coloured tubular. flowers in clusters, and require treatment similar to the wax-plant. (Soil No. 2.) Ardisias, about eighteen species. Plants highly esteemed for the beauty of their foliage, flowers, and berries. The most popular in our collections is A. crenuldta. It has rose- coloured star-like flowers, in terminal panicles, and produces beautiful small red berries, which continue until other ber- ries are produced the following year; and frequently there may be seen on one plant the berries of three successive years, thus being a very ornamental plant and very desira- ble. It is vulgarly called the dwarf ever-bearing cherry. It will keep in a good green-house, but not grow freely. A. so- landcea has large oblong leaves, narrowed at each end, and bears purple berries; A. élegans has entire, oblong, shining leaves; A. umbellata, once A. littordlis, is also a fine plant for an abundance of flower and beauty of foliage. The flowers are pink, in large decompound panicles. Allamanda, a family of half climbing plants, with large chrome-yellow blossoms, requiring plenty of pot-room and good culture to flower well. A. cathdrtica, A. neriifotia, and A. schottii, we consider the finest. (Use soil No. 13.) Aphalandra cristata, a new plant with a brilliant spike of flowers about six inches long crowning the plant. (Use soil No. 9.) Aréca, Cabbage-tree, ten species. They are a kind of palms, with large pinnated leaves, or properly fronds. In their indigenous state they are from six to forty feet high, but in the hot-house they seldom exceed twenty feet. A. cdtechu is used in medicine. A. olerdcea is cultivated exten- pively in the West Indies, and the tender part of the top * These numbers refer to the table of soils at the end of tha work. May. | HOT-HOUSE—OF REPOTTING, ETC. 153 is eaten by the natives. A. montand is most frequent in collections There is no particular beauty in the flowers. They are all easily grown, if plenty of heat be given. (Soil No. 12.) Aristoléchias, Birth-wort. There are several of these be- longing to the hot-house, but none of them deserving par- ticular observation, except A. labidsa, A. gigas, and A. bra- siliénsis. The leaves are reniform, roundish, cordate, and amplexicaule ; the flower or corolla is of a curious construc- tion, being incurved, and at the base swelled or saccate, with a large lip, and all beautifully spotted ; colour greenish brown. They are climbing plants, and require a strong heat. (Soil No. 9.) Astrapeas, three species. A. Wallichii is a celebrated plant in Europe, and is frequently met with in our collec: tions. It has a profusion of scarlet umbellated flowers, with an involucre; has twenty-five stamens united into a tube, bearing the corolla with five petals; leaves roundish, cordate, acuminate, very large, with persistent, ovate wavy stipules. The plant is of easy culture, and grows freely, wood very strong. (Soil No. 12.) Bambisas, Bamboo-cane, two species. Plants of very strong growth, and are used in the East Indies, where they are indigenous, for every purpose in the construction of huts, for furniture both domestic and rural, for fences, boats, boxes, paper, &c. It is frequently used as pipes to convey water. The species thus useful is B. arwndindcea, which grows to a great height. We do not mention it as interesting in beauty, but as a valuable plant for the many useful purposes to which it is applied. It requires to be kept wet. (Soil No. 15.) Banistérias, a genus of about fourteen climbing evergreen plants. Three of them are esteemed, B. fulgens, yellow flowers in racemose spikes, leaves subovate and downy be- neath. B. chrisophylla has beautiful foliage, as if covered with a shining gold-coloured dust ; leaves large, oblong, acute. B. spléndens, flowers in spikes of a yellow colour; foliage large and silvery-like ; the pots should be well drained. (Soil No. 9.) Beauméntias are strong-growing, climling plants, with large foliage. B. grandiflora is said to have beautiful large white flowers approaching the Oleander. (Soil No. 12 ) lot HOT-HOUSE—OF REPOTTING, ETC. — [May, Bletias, a genus of about eight species, all beautiful flow- ering plants. B. Tankervillie is most superb, a small plant, now (Jan). in bloom, has upward of fifty full-blown flowers, besides many buds—they are brown, white, and purple, and about two inches in diameter. When out of flower, and the roots become dormant, place the pots in a shady situation ; allow the soil to become dry, until the roots begin to grow : as soon as this is observed, repot the plants and expose them fully to the sun, giving plenty of water while growing. B. Shépherdii is a fine pink, and requires similar treatment. (Soil No. 13.) Bignonia, a very beautiful family of climbing plants, some of them gorgeously covered with bloom half of the year. B. venustd has large clusters of bright orange-coloured flowers in great profusion from December to May. JB. picta, violet and hilac-coloured striped flowers. B. chamberlyana, yellow flowers with rich foliage. They should be planted into large pots or tubs, or if prac- ticable, into the ground, in the interior of the house, giving them plenty of space to climb, using soil No. 9. Brunfélsias, very fine, free-flowering plants, with white, yellowish, or purple flowers. B. grandiflora blooms freely, and is finely scented—a plant before me now (28th of Jan). only one foot high, has six full expanded flowers upon it, each fully two inches in diameter. (Soil No. 9.) Buonapdrtea jiuncea, a very curious low-growing plant, with long narrow, recurved, round leaves; with spikes of small green flowers. There does appear to be three distinct pho in cultivation, but are rarely attainable. (Soil No. 12. Biddlea madagascartensis blooms profusely during winter in spikes of orange-coloured flowers, of a kind of honey fra- rance—the plant is strong-growing, and of the easiest culture. (Soil No. 11.) _Calathéa zebrina, frequently known as mardnta zebrina ; it is a plant unique in appearance, having large elongated ovate leaves, beautifully striped with green and dark pur- ple, and called the Zebra plant. It has light blue flowers in ovate spikes, about the size of large pine cones. It is an herbaceous plant; but in the warmest part of the hot- house retains its splendid foliage; requires a very liberal May.] HOT-HOUSE—OF REPOTTING, ETC. 155 supply of water, and ought to be in every collection. (Soil No. 11.) Cannas, about thirty species, several of them deserving cultivation both for flower and foliage; they are principally aatives of the West Indies. The finest are C. gigantea, has farge leaves and orange flowers; ©. limbadta, flowers scarlet and yellow; C. discolor, has large cordate, acuminate leaves of a erimson colour, C. iridiflora, has large crimson flowers. They all, while in a growing state, require a liberal supply of water, and being herbaceous plants, watering ought to be given up about the first of November, and renewed in Febru- ary, thus giving them a cessation which they require to flower freely ; but when water is constantly given, which is the gene- ral plan in our collections, they continue to push weak shoots and few flowers. They also do very well by planting them as ornamental plants in the garden during summer, where they bloom profusely, and their large roots can be placed in the cel- lar all winter, where they will be free from frost. (Soil No. 12.) Cactus.—This extensive genus is interesting, and varied in character and habit; it is now divided into seven distinct genera, according to their natural appearance and disposition. We will describe a few of each genus, none of which going under the name of Cactus, we will give them the six follow- ing, premising that the time is not far distant when this family will be successfully cultivated in every parlour-window, and the whole tribe will be sought for with more avidity than any other class of plants that have ever been brought to notice, not even excepting the Jose. They require a dry heat, and wit grow either in town or country, and are com- pletely adapted ror the denizen amateur, and will afford more beauty and interesving display than can be imagined until witnessed. Mamillarias, about seventy species, and are those which are covered with roundish pearded tubercles, and with small red and white flowers. M. cocctnea, M. simplex, M. pusilla, VM. cénica, M. stellata, and M. acanthiphlegma, are good species, and will do well with water once a week during sum- mer. (Soil No. 15.) m Melocdctus, seven species, and are those that are roundish with deep and many angles, with spines in clusters on the top of the angle. M. commimis is the Turk’s cap, named 156 HOT-HOUSE—OF REPCLTING, ETC. [May from having an ovate conate crown upon the top, from which proceed the small red flowers. MM macrdnthus has large spines; JL pyramiddlis is a conical growing species. These require the same treatment as the fast. (Soil No. 15.) Echinocdctus, a great number of species; are those that have many deep angles, and have a remarkable swelling with each parcel of spines; H. gibbdésus, E. crispatus, LH. rectirvus, E.. rodanthia, and E. scopa, are curious in appearance, with small white and purple flowers. These three genera in most collections are not well known specifically, but it is easy to discriminate with which genus they are connected. (Soil No. 15.) Céreus.—This is the most magnificent genus with regard to the magnitude and beauty of the flowers, but not so closely allied in character. It takes in all those of a trail- ing or erect growing habit, having spines in clusters, solitary, or spineless. O. senilis is the celebrated monkey cactus. C. peruvidnus and C. heptagonus grow very erect, and to the height of thirty or forty feet in Peru and Mexico, where » they plant them close together as fences, and they are in a few years impenetrable. C. flagelliformis is a well-known creeping flowering species, has ten angles; will keep in a good green-house, and produce in May and June a great number of blooms. ‘The petals are of a fine pink and red colour; the tube of the flower is long, and will stand a few days in per- fection, when others come out successively for the space of ‘two months, and during their continuance make a brilliant appearance. ©. grandiflorus is the celebrated ‘ Night- blooming Cereus.” The flowers are very large, beautiful and sweet-scented. They begin to open about sundow., and are fully expanded about eleven o'clock. The corolla, or rather calyx, is from seven to ten inches in diameter, the outside of which is a brown, and the inside a fine straw yel- low colour; the petals are of the purest white, with the stameus surrounding the stile in the centre of the flower, which add to its lustre, and make it appear like a bright star. Its scent is agreeable, and perfumes the air to a considerable distance ; but these beauties are of momentary duration. By sunrise they fade, and hang down quite decayed, and never open again.* One of these ought to be in every collection, and, * They may be preserved if cut off when in perfection, and put in May.)

Scottii are nearly alike, and have beautiful scarlet flowers: it has been gratuitously (to say the least of it) called “The Scarlet Night: blooming Cereus.’ C. speciosissimus has most beautiful large flowers, about six inches in diameter; the outside petals are a bright scarlet, those of the inside a fine light purple. One flower lasts a few days, and a large plant will produce every year from ten to fifty flowers, and blooming from May to August. ( Maynardii has very large orange-scarlet flowers, about nine inches in diameter, blooming during the day. C. Fielderii is of a brilliant bluish violet colour, even more of the peculiarly blue tints so greatly admired in spe- ciosissimus. C. trianguldris has the largest flower of the Cactew family ; the bloom is of a cream colour, and about one foot in diameter. In its indigenous state it produces a fine fruit called ‘Strawberry Pear,” and is much esteemed in the West Indies as being slightly acid, and, at the same time, sweet, pleasant, and cooling. Epiphyllums are those species of the Cacteze family which have flat shoots, or leaves without spines; from the edges of those leaves the flowers are produced. They are exten- sively cultivated for their profusion of bloom, and are fre- quentlv grafted on Cereus trianguldris and Peréskia, which greatly promotes their growth, and prevents them from so easily damping off by over-watering. The original species are LH. speciosum, pink; EL. phylanthoides or Hoékerii, white ; E. aldtum, white; FE. truncdtum, scarlet; flowers tubular, from two to three inches in diameter: The plant is of a very dwarf growth, and much branched; when in bloom, it is quite a picture, and rendered more beautiful when grafted. There are three varieties of truncdtum, differing from it in colour, or rather shades of colour: Altenstéinii, rosy red; violacea, very beautiful violet and white; rubens, bright red. E. Ackermania has a magnificent large crimson flower. Be- sides these, there are many superb hybrid varieties, vying with any of the originals. Among them are the following: E. crinitum, pale yellow crimson quite new, of fine habit; spirits of wine, in a glass vase, made air tight. A plant flowered in our collection in May, 1830, at 12 o’clock at noon—the only instance of the kind we ever heard of. 14 158 HOT-HOUSE—OF REPOTTING, ETC.

All the Epiphyllum tribe require a very rich open soil, not of too sandy a nature, as they thereby grow to wood, and bloom but sparingly—give plenty of drainage. (Soil No. 18.) Opuntias, upwards of fifty species, and are those whose branches are in thick joints, flat, oblong, or ovate; spines solitary or in clusters. Some of the plants are very desirable for their singular appearance, and some of them, particularly O. cochinillifera, are valuable for feeding the Cochineal insect. O. microddsys, O. ferdx, O. lacte-spina, O. sericed, and some others, are beautiful plants, and will grow in any kind of soil, but No. 2 will suit them best. Peréskias.—About four species, and those that are of a shrubby nature, producing leaves: P. aculedta bears a fruit called, ‘‘ Barbadoes gooseberry.” The flowers are very small and simple, spines about half an inch long, leaves fleshy and elliptical. (Soil No. 2.) The whole of the plants in the family of Cactew require very little water in winter, and delight in a dry, warm situa- tion. They do not agree with very frequent repotting ; once a year to young plants, and in two or three to those that are established, with the exception of the large, free-flowering species, which should be repotted once in two years, and never be allowed to shrink for want of moisture. The operation of grafting is very simple, merely requir- ing an incision to be made, and fitting in it a fresh cutting of another kind, holding the cutting stationary in the inci- sion half a minute, till the juices of the two adhere together, when it may be said the union is effected, and, in a few weeks, the new branches will grow freely. We have seen the Mammillaria tribe growing neatly upon the triangularis, and other species of the cereus.

Céryphas (Large fan Palm), five species of the most noble and magnificent of palms. C. ambraculifera, the fronds or leaves are palmate. In Ceylon, where the tree is indigenous, they are frequently found fifteen feet wide and twenty feet long.

(Soil No. 12.) Crinums, about one hundred species, chiefly stove bulbs, many of them beautiful. Those that are of great celebrity are C. erubéscens, pink; C. scdbrum, crimson and white; C. amabile, purple and white; the neck of the bulb of the latter is long, is easily distinguished by its purplish colour, and is unquestionably the finest of the genus. Several specimens of it are in our collections. Their flowers are in umbels, on a statk about threé feet high; corolla funnel- shaped; petals recurved; nearly fifty flowers on each stem. and a good plant will produce three stems im one year. They require large pots to make them flower well, and, when growing, should be liberally supplied with water. (Soil No. 12.)

We have seen a beautiful specimen of it which is kept every winter in the cellar; but those that are kept so cool in winter only grow every alternate year, while those that are kept in the hot-house grow every year, which shows that heat is their element. C. circindlis is a large-growing species; the fronds are much longer, but not so close and thick. C. glauca is a fine species: the foliage is slightly glaucous. They require plenty of pot-room, are much it- fested with the small white scaly insect, and ought to be fre quently examined and carefully washed as prescribed in January. (Soil No. 12.)

Plenty of heat is indispensable to make it flower in perfection; therefore it should have the warmest part of the house, and it will produce flowers of a fine blue colour from December to April. The flowers of the latter are white and dark purple, with a few brown spots in the white: blooms from April to August. Drain the pots well, and give the plants little sun during summer. (Soil No. 11.) Eugénias, about thirty species, esteemed for their hand- some evergreen foliage. This genus once contained a few celebrated species, which have been divided. (See Jam- bosa.) The Allspice tree, known as Myrtus Piménta, is now H. Pimenta; the leaves are ovate, lanceolate, and, when broken, have an agreeable scent. There are several varie- ties, all of the same spicy fragrance. The plant is in very few of our collections. . fragrans is sweet-scented; the flowers are on axillary peduncles; leaves ovate, obtuse. (Soil No. 11.) Euphérbia (spurge), a genus of plants disseminated over every quarter of the globe; a few are beautiful, many gro- tesque, and several of the most worthless weeds on the earth. There are about two hundred species, and from all of them, when probed, a thick milky fluid exudes. Those of the tropics are the most curious, and very similar in appearance to Cdctus, but easily detected by the above perforation There is a magnificent species In our collections, which was lately introduced from Mexico—(see Poinsettia). E. splén- dens flowers freely from December to May, and is of easy culture. H. fiilgens, same as jaquiniiflora, is a plant of a slender willow-looking habit, but produces a profusion of flowers from the axil of each leaf, which renders it very showy. The flowers of the whole genus are apetalous, and the beauty of those described is in a brilliant scarlet bractea, which is very persistent. They must have plenty of pot- room. (Soil No. 9.) Erythrinas (Coral tree), a genus containing about thirty species of leguminose, scarlet-flowering plants. Several species are greatly esteemed for their beauty and profusior of flowers, which, in well-established plants, are produced in long spikes. 2. corallodéndrum blooms magnificently ir the West Indies, but in our collections has never flowered.

LZ. specidsa is a splen- did flower, leaves large, ternated, and prickly beneath; stem prickly. £. pubéscens is valued for its large, peculiar brown pubescent leaves. . princéps is quite a new species, and is represented as being the finest of all the Hrythrinas, and exhibits its rich crimson flowers in great profusion; to make them grow well and bloom freely, they require plenty of pot- room; indeed, while in a growing state, they should be re- potted every month. In regard to EZ. herbacea, which is a native of the Carolinas, and frequently trea'ed as a hot-house plant, it is our opinion that it would be moe perfectly grown if planted about the first of the month in the garden; and, when growing, if well supplied with water, it would flower from July to September. About the first of November lift the roots and preserve them in half dry earth. Z. laurifolia and &. cristagdlli are likewise often treated as hot-house plants, and in such situations they cast prematurely their first flowers by the confined state of the air. They will keep in perfect preservation during winter ina dry cellar, half covered with earth, or entirely covered with half dry earth; conse- quently, the best and easiest method of treatment is to plant them in the garden about the first of May, and, when grow- ing, if the ground beeomes dry, give them frequent waterings. They will flower profusely three or four times in the course of the summer. We freely recommend the last species to all our patrons, confident that it will give ample satisfaction, both in profusion of flower and beauty of colour. The soil they are to be planted into should be rich and well pulverized ; or, if they ure kept in pots, they must be enlarged three or four times, when they are in a growing state, to make them flower per- fectly; otherwise they will be diminutive. (Soil No 13.) Ficus, Fig-tree, a genus containing about fifty hot-house species, besides several that belong to the green-house : greatly admired for the beauty of their foliage. A few of them are deciduous, and all of the easiest culture. We have seen plants of F. eldstica hung in the back of the hot-house, without the smallest particle of earth, their only support being sprinklings of water every day.

(Soil oN; ) Gardénias, a genus containing about seventeen species, several of them very popular in our collections, going under the name of Cape Jasmine, which do well in the green-house (see May). The species requiring this department, and de- serving attention, are G. Sherbournii, with large spotted flowers; G. Stanleyana, flowers of a greenish white colour, nine inches long, spotted with brown, splendid; they require to have the pots well drained. (Soil No. 13.) Geissoméria longiflora. This is a new genus, and closely allied to /?uéllia. The species alluded to is a free flower, blooming from January to May, in close spikes of a scarlet colour, leaves opposite, ovate, elongate and shining; the plants must be well drained, and in summer kept from the direct influence of the sun. (Soil No. 2.) Helicénia braziliensis. This very splendid plant is nearly related to Strelitzia, and in splendour surpasses it. The brilliant scarlet sheath that envelops the flowers contrasts most admirably with its rich green leaves. Give plenty of drainage to the pots, and, when the plants are growing, give a liberal supply of water. (Soil No. 17.) Heliotripiums, about twelve species, of little merit, except H. peruvianum, H. intermedia, H. valitariana, pale bluish white; H. fleur de Liege, represented as yellow, but is only a very dull white, with a faint yellow eye; these are all very agreeably scented, especially the two former, which are uni- versal favourites.

The plants grow freely, and produce their flowers three or four inches in diameter, from the young wood; the leaves are ovate, acuminate, smooth, entire at the base, and coarsely teethed at the end. All the varieties are of the same character, and highly deserving of a situation in every collection. There is said to be a double white variety, which we doubt. A mutabilis fldre pléno is a splendid plant, of strong growth, and will, when well established, flower abundantly, if the wood of last year is cut to within a few eyes of the wood of the previous year; the flowers are produced on the young wood, and come out a pale colour, and change to bright red, and about the size of a garden Provins rose; leaves downy, cordate, angular, five-lobed, acuminate, and slightly in- dented. HH. lillii-florus is a new highly esteemed species ; the flowers are various in colour, being pink, blush, red, and purple. The leaves vary in character, but are generally cordate, crenate, acuminate; the petioles are brown, and the whole slightly hirsute; is deciduous, and requires to be kept in the warmest part of the house.

H. carnosa is a fine flowering species, and known in our collec- tions as the wax-plant; the leaves are green and fleshy ; the flowers are mellifluous, five-parted, and in pendulous bunches, slightly bearded, and have every appearance of a composition of the finest wax; of a blush colour. H. cras- sifolia, H. grandiflora, brown flowered, H. bella, variegated, H. Cunninghamii and H. imperialis are all well worthy of cultivation. (Soil No. 2.)

The fruit is about an inch in diameter, eatable, and smelling like a rose, hence called ‘‘ Rose Apple.”’ The petals of all the species are simple, and may rather be considered the calyx; the beauty of the flowers is in the many erect spreading stamens, either straw, white, rose, or green colour. J. malaccénsis, Malay Apple, is greatly esteemed for the de- lightful fragrance of its fruit. We frequently see J. purpu- rascens, which is a native of the West Indies, going under J. m., which is an Asiatic species, with white flowers and entire oblong leaves; whereas, the leaves of J. p. are small, ovate, acuminate ; the young shoots and leaves are purple. J. ma crophylla, white, and J. amplexicadlis, green, have very long oblong, lanceolate leaves, and are of a strong, woody habit. They are all easy of culture. (Soil No. 11.)

Jatropha, Physic-nut, is a genus of six strong-growing shrubs, natives of the West Indies. J. multifida and J. pandurefolia have the handsomest foliage, and both have scarlet flowers; the appearance of the foliage of this genus is the only object: the flowers are small, in coarse disfigured panicles, and several of the species have not been known to flower in artificial cultivation. The seeds of J. ctircas are vften received from the West Indies; the leaves are cordate, angular and smooth. J. manthot, now Manihot cannabina, is the Cassada root, the juice of which, when expressed, is a strong poison. They are all easy of culture; want of strong heat in winter will make them cast their leaves, but does them no other injury. (Soil No. 17.) Justicia.

Mexicana, very rich orange, one of the finest. These are very handsome growing plants, and will even keep in a good green-house; but in such case will only bloom in summer. They will not bear a strong fumigation ; therefore, when the hot-house is under that operation, they must be set down in the pathway, or other jow part in the house. (Soil No. 9.) Lasiandra, a genus related to melastoma, of which there are several very handsome species. L. splendens, with hirsute rich crimson foliage and brilliant purple flowers, blooming from January to May. JL. Benthamiana, with very elegant foliage and rich bluish purple flowers, grows freely in Soil No. 1. Latanias. This genus contains three species of handsome palms. JL. barbonica is one of the finest of the Palme, not growing to great magnitude; the leaves or fronds are plaited flabelliform, leaflets smooth at the edge, footstalk spiny, and the plant spreading. JL. ribra, fronds same as the former, but leaflets more divided and surrulate; footstalk unarmed : foliage reddish. JL. glaucophylla same as L. ribra, only the foliage glaucous.

C. vérum is the true Cinnamon of com merce. The part taken is the inside of the bark when the tree is from five to eighteen years old. The leaves are three- nerved, ovate, oblong; nerves vanishing towards the point, bright green above, pale beneath, with whitish veins. This plant ought to be kept in the warmest part of the hot-house. C. cassia is frequently given under the former name, but when compared, may be easily detected by the leaves being more lanceolate and a little pubescent. They both make handsome plants, but require great heat. Drain the pots well of the delicate sorts. (Soil No. 13.)

M. fn- dica is in our collections, and bears a fruit which is so highly esteemed in the East Indies as to be considered preferable to any other, except very fine pine-apples. The leaves are lanceolate, and from six to eight inches long, and two or more broad. The flowers are produced in loose bunches at the end of the branches, but of no beauty, and have to be artificially impregnated, or it will scarcely produce fruit. The shell is kidney-shaped, and of a leathery crustaceous sub- stance. They contain one seed, and in their indigenous state are more juicy than an apple. Drain the pots well, as the roots are apt to get sodden from moisture. The other species goes under the name of oppusitifolia, but we question if it is not only a variety, for it has every character of the one just described. (Soil No. 11.) Merica, a genus of hot-house plants, closely allied to Jris, between which there is no distinction in the leaves.

There are about thirteen species remaining in the genus. They now display great unity of character, and many of them may be considered very ornamental. The finest are MM. heteromalla, bluish purple, and an abundant bloomer; MM. malabbathrica, rose-coloured; MM. sanguinea, lilac; Jf. splendens, large violet; and AM. aspera, rose. There is a plant in several of our collections known as J. purptrea and M. tetragona, which is Osscea purpurascens ; leaves ovate, lanceolate, acuminate, five-nerved, pilose; the footstalk and nerves underside of the leaf covered with brown hairs; stem four-sided; flowers purple. All the species are easy of culture. J. nepalénsis is a green-house plant. (Soil No. 1.) Mandevilla Suavedlens, or Chili Jasmine: this beautiful climber is a native of South America; the flowers are in clusters and nearly bell-shaped, white, and of exquisite fra- grance; the bloom is produced on the extremity of the shoots. After the flowering season, the plants should be pruned back to within a few eyes of the preceding year’s wood. (Soil No. 13. Medinilla, 1 new family of tropical plants, magnificent for the grandeur of their foliage and the profusion of pink flowers, which they produce at nearly all seasons of the year. M. erythrophylla, M. radicaus, M. Speciosa and M. Stebol- diana, are all easily cultivated. (Soil No. 12.) Musa (Plantain tree), contains eight species, and is greatly esteemed in the East and West Indies for the luscious sweet flavour of its fruit, which can be converted into every delicacy in the domestic cookery of the country. M. paradistaca is the true plantain tree, has a soft herbaceous stalk, fifteen or twenty feet high, with leaves from five to seven feet long, and about two feet wide. MM. sapiéntum is the true banana tree ; habit and character same as the former, except it has a spotted stem, and the male flowers are deciduous. The pulp of the fruit is softer, and the taste more luscious. M. rosdcea, M May.] HOT-HOUSE—9OF REPOTTING, =:TC. 171 roccinea, and M. chinénsis, are more esteemed in artificial cul- tivation for their flowers, and for being smaller in growth M. Cavendishit produces immense clusters of ripe and well- flavoured fruit, plants only four feet and a half high ; will yearly produce about eighty pounds. M. décca is another dwarf species, and in 1838 ripened a cluster of fruit in the Royal Botanic Gardens of Edinburgh which weighed fifty pounds. These dwarf bananas are now being cultivated in Kurope expressly for their fruit, which is very delicious when perfectly ripened. They are Chinese plants, and will soon be introduced into the West India Islands, where they will entirely supplant the large varieties. Myrtus Piménta, or, more properly, Piménta Vulydris, is the Jamaica pepper or allspice; there is no beauty in the flowers—the leaves are highly aromatic, and it is a handsome evergreen. (Soil No. 9.) Nepénthes (Pitcher-plant). There are two species of this plant. N. distillatoria is an esteemed and valuable plant in Huropean collections, and we are not aware of there being any in this country, except in Philadelphia. The leaves are lanceolate and sessile; from their extremity there is a spiral, attached to which are long inflated appendages that are generally half full of water, which appears to be confined within them by a lid with which the appendages are surmounted; hence the name of pitcher plant. We have never observed the lids close again when once open. Writers have called it an herbaceous plant, but it is properly aclimbing shrub. The pot in which it grows should be covered with moss, and the roots liberally supplied with water every day. It delights to be in a moist state. The flowers are small, and in long spikes. The plant is of easy culture, and even rapid in growth: a plant with us only nineteen months old is now five feet high. (Soil No. 5.) Pancratium is a genus of hot-house bulbs, and now only contains five species. They are all free-flowering. Several of them are handsome and fragrant. P. maritimum and P. verecindum are the finest; the flowers are white, in large umbels; petals long, recurved, and undulate. P. Littoralis, P. speciosum, and P. caribeum, are now given to the genus Hymenocdllis, and are fine flowering species. Care must be taken not to give them water while dormant.

There are about twenty species in this genus, several of them very interesting, but none se greatly admired as P. odoratissimus. The leaves in estab- lished plants are from four to six fcet long, on the back and edges spiny; are spreading, imbricated, and embracing the stem, and placed in three spiral rows upon it. The top soon becomes heavy, when the plant throws out prongs one, two, or three feet up the stem in an oblique descending direction, which take root in the ground, and thus become perfectly supported. It is cultivated in Japan for its de- lightful fragrance, and it is said, “‘of all the perfumes, it is by far the richest and most powerful.” P. dtilis, red- spined. We question this species, and are inclined to believe that it is the former, only when the plants are newly raised from seed the spines and leaves are red, changing to green as they become advanced in age. The plants are easy of culture, and will grow almost in any soil. (Soil No. 123) Passifléra, “ Passion-flower, so named on account of its being supposed to represent in the appendages of its flower the Passion of Jesus Christ.’ There are about fifty species, all climbing plants, that belong to the hot-house. Many are of no ordinary beauty; a few species are odoriferous ; others bear edible fruits, though not rich in flavour. P. aldta is in our collections, and greatly admired; the flowers are red, blue, and white, beautifully contrasted, and flower profusely in pots. P. racemésa, red flower. P. cerileo-racemésa, purple. P. quadrangularis has beautiful red and white flowers. The plant is iv. several collections, but has seldom flowered; it requires to be planted in the ground to make it flower freely, and it will also produce fruit. P. picturdta is a scarce and beautiful ;arious-coloured species. P. kerme- sina, bright rosy erimson, and, beyond all question, the most profuse flowering apecies now in cultivation, and will do well in a good green-house. LP. Loudénii, bright crimson. P. edulis is cultivated for its fruit. There are many other fine species, but these are the most esteemed sorts; and, when well established, will flower profusely from May to August They are desirable in every collection, and will take only a May.] HOT-HOUSE—OF REPOTTING, ETC. 175 small space to hold them, by training the vines up the rafters of the hot-house. (Soil No. 13.) Phenix, Date-palm, about eight species, principally Asi- atic plants. The foliage is not so attractive as many others of the palm family, but it is rendered interesting by producing. a well-known fruit called Date. P. dactylifera will do very well in a common green-house. In Arabia, Upper Egypt, and Barbary, it is much used in domestic economy. P. palu- désa has the most beautiful foliage, and the best habit. The flowers are diccious. (Soil No. 12.) Plumbdgo résea is a pretty free-blooming plant, with con- tinued profusion of red flowers ; it requires plenty of heat ana a good drainage. (Soil No. 11.) Plumérias, above twenty species. Plants of a slow growth, robust nature, and are deciduous. ‘The foliage is greatly ad- mired. The plants are shy to flower, but are brilliant in colour. P. acumindta has lanceolate, acute leaves, flowers corymbose and terminal. P. tricolor has oblong, acute, veiny leaves; corolla red, yellow, and white. This and P. rubra are the finest of the genus. They ought not to get any water while not in a growing state. (Soil No. 11.) Poinséttia* pulcherrvma. When well cultivated, this i truly the most magnificent of all the tropical plants we have ever seen; from December to April, it is crowned with flowers, surrounding which are bright scarlet whorls of brac- tex, frequently measuring twenty-two inches in diameter. To grow it to such perfection, we treat it as follows: in April we cut the young wood down to within two inches of the wood of the preceding year, and reduce the ball of earth, put- ting it into a smaller pot. About the end of May we plant it in the open ground, in light rich soil, giving it one or two waterings after planting. During summer it will grow three or four feet ; about the end of September, it is carefully lifted and potted into a large-sized pot, and put into the hot-house, sarefully shading it for a few days—when it requires no more attention except a regular supply of water, and to be kept in a temperature of from 55° to 75°. There is also a pale yel- * Named by Professor Graham, of Edinburgh, in compliment to the Hon. J. R.

Rondelétia speciésa is a new and rare plant, in every re- spect equal, if not superior, to Jxdra céccinea; its large corymbs of orange-red flowers have a very striking appear- ance, and it is easily cultivated in soil No. 1. It should have frequent repottings when growing. Ruéllia. There are a few species, very pretty flowering plants, of easy culture. 2. formosa, flowers long, of a fine scarlet colour; plant half shrubby. FR. fulgtda has bright searlet flowers on axillary long-stalked fascicles. A. persi- cifolia, with unequal leaves and light blue flowers, is now called R. anisophylla. (Soil No. 10.) Russélia juncea, a slender plant of an upright habit, pro- ducing, when well grown, a profusion of scarlet tubular flowers, about one inch long each: it is of the easiest culture in soil No. 19. Sdgus, Sago palm. We are of opinion that the true palm from which the sago of the shops is produced has not been introduced into our collections. It is very rare in the most extensive collections of Europe, but it is not so fine a plant as the one we have under the Sago, which is placed in the natural order of Cycadeer; and Sagus is in that of Palme. The finest of this genus is S. vintfera and S. Riuimphii. They grow to a great height; even in artificial cultivation they may be seen from ten to twenty-five feet. We have not ‘ntroduced them here for their beauty, but to prevent error. (Soil No. 12.) Soldndra, a genus of four species, remarkable for the ex- traordinary size of their flowers, and are considered beautiful. S. grandiflora and S. viridiflora are the best two. The plants will bloom well if they are restricted in pot-room, and are only introduced as being worthy of cultivation. If they are repotted once in two or three years, it is sufficient, except where the plants are small and want encouragement. (Soil No. 13.) - flay. HOT-IL0USE—OF REPOTTING, ETC. 175 7 Strelitzia, a splendid genus of noble-looking plants, all of which do perfectly well in the green-house, except S. augiista, the flowers of which are pure white ; the leaves are very large, being nearly six feet long and eighteen inches wide, and assume the appearance of the Banana tree: it requires great space for its roots.

Swieténia (Mahogany tree), the wood of which is celepra- ted in cabinet work. S§. mahégoni, common. This tree varies much in general appearance, according to soil and situation. The leaves are pinnated in four pairs; leaflets ovate, lanceolate ; flowers small, white, in axillary panicles S. fubrifiga, leaves pinnated, in four pairs; leaflets ellipti- cal; flowers white, in terminal panicles. The wood of the last is the most durable of any in the East Indies. They are fine plants, and require heat and pot-room to produce flowers. (Soil No. 15.) Taberneemontana, a genus of little beauty, except for one or two species. A plant known in some collections as Nérium corondrium, is now, and properly, 7’. corondria. The variety flore pléno is the one most deserving of culture, and will flower profusely from May to August; the flowers are double, white, fragrant, and divaricating. The plant will lose its foliage if not kept in a strong heat; therefore place it in the warmest part of the hot-house. 7’. densiflora is a fine specics, but very rare. Drain all the plants well, and keep them in the shade during summer. Tecoma, a genus of plants closely allied to Bignénia, and are free-flowering ; several of them much esteemed. 7’. mdllis, T. digitdta, and T. spléndida, are the most beautiful of those that belong to the hot-house. They have large orange-coloured, tubular, inflated, ringent flowers, in loose panicles. There is a plant known in our collections as Bigndnta stdns, which is now 7’. stins; has pinnated leaves, with oblong, lanceolate, #6 HOT-HOUSE—OF REPOTTING, ETC.

T. coccinea, red; T. grandiflora, blue; T. fragrans, white sweet-scented; 7’. aldta has pretty buff and purple flowers, which are in great profusion. If sown in May, they will bloom from July until killed by frost. 7. chrysops, beauti- ful blue, with a dark brown eye, a plant of dwarf habit re- quiring partial shade. This makes a very pretty annual in the flower-garden, with its beautiful white variety, forming an elegant contrast. (Soil No. 13.) Torénia Asidtica, an exquisite tropical, soft-wooded plant, producing a profusion of waxy, porcelain blue flowers, tipped with rich violet purple, in constant succession, requiring par- tial shade and frequent sprinklings of water over the foliage. It also succeeds admirably out of doors in the summer sea- son, where the situation is moist and half-shady. (Soil No. 13.) Tradescdntia discolor. Purple-leaved spider wort. This 1s an herbaceous plant, and is only cultivated for its beauti- ful purple foliage. It has curious small white flowers. (Soil No. 10.) Urdnia speciésa, a gigantic-looking plant closely connected to Musa, from which it differs in habit by the large leaves being more erect: to grow it luxuriantly, give it plenty of heat, water, and pot-room.

HOT-HOUSE—OF BRINGING OUT, ETC. li7 J ) cca, Z. ténuis, Z. integra ifolia, are the most showy that belong to the hot-house. The whole genus is frequently kept in this department. They are all plants of a slow growth, and the beauty is entirely in the pinnated fronds, with from ten to forty pairs of leaflets. The pots must be well drained (Soil No. 11.) Those genera of plants which we have enumerated under the head of repotting in this or next month, are composed of the finest hot-house plants that have come under our observa- tion. There are perhaps a few of ‘hem that are not to be found in the United States, or even on our continent; but the great object in a choice collection of plants, is to have the finest from all parts of the known world. There are many plants whose nature does not require much support from soil, which is frequently observed in those that are mentioned. And there are many hundreds of plants desirable for beauty, ornament, and curiosity, which would take volumes to specify and describe. In fact, every year brings many new things, and frequently both new and splendid, either in flower, fruit, or foliage. We have previously observed, that plants ought not to be flooded with water when newly potted, as it saturates the soil before the roots have taken hold of it; and that the best draining for pots is small gravel or pot-shreds broken fine. We wish it to be understood that, when plants are repotted, any irregular branch or shoot should be lopped off that can- not be tied to advantage. And repotting may take place either before or after the plants are exposed to the open air, according to convenience. OF BRINGING OUT THE HOT-HOUSE PLANTS. When the hot-house is very crowded with plants, the best method to have them exposed without danger is to take out those of the hardiest nature first, that have no tender shoots upon them, thereby thinning the house gradually. This may be done from the sixteenth to the twenticth of the month, which will admit of a free circulation of air among those that remain. All may be exposed from the twenty-fourth to the twenty-eighth of the month. This is a general rule, though in some seasons there may be exceptions. Having previously 178 HOT-HOUSE—OF BRINGING OUT, ETC. [ May. given all the air possible to the house, that no sudden transi- tion take place, which would make the foliage brown and otherwise materially injure the plants, choose calm days for the removing of them. There are few plants while in pots that agree with the full sun upon them; or, if the plants receive the sun, the pots and roots ought not. The best situation for them ‘ig on the north side of a fence, wall, house, or other building, where they are excluded from the mid-day sun, and they should stand on boards or gravel, with the tallest at the back, firmly tied to a rail, or some other security, to prevent them from being overturned by high winds. Make a fanciful bed, and cover it with sand or coal ashes, for the reception of the smaller plants, and setting them thinly and regularly thereon is preferable to crowding them with the taller sorts. And it may be desired to have some of the plants plunged in the garden through the flower borders. Of these that are so treated, the pots must be plunged to the brim, and regularly turned round every two weeks, to prevent the roots from running into the earth. If the roots were allowed to do so, it might for the present strengthen the plant, but ultimately would prove injurious. Where a sufficiency of shade cannot be obtained, it would be advisable to go to the expense of a very thin awning, that would not exclude the light, but merely the powerful rays of the sun, attending to roll it up every evening. Plants will keep in beautiful order by the above method, which amply repays for the trouble or expense. Avoid putting plants under trees; comparatively few thrive in such situa- tions. When they are thus exposed to the open air, it will be very little trouble to give them a gentle syringing every evening when there is no rain, and continue your usual examinations for insects; when they appear, resort to the prescribed reme- dies. Green-fly will not affect them, but the thrips may. (ive regular supplies of water every evening, and again in the morning to all that require it, carefully examining those that are in small pots. June, July.) HOT-HOUSE—OF REPOTTING, ETC. 179 SUCCULENTS, OR THE CACTZA TRIBE, The Céreus Mammillaria, and Opintia. Divisions of tnis family are, in their indigenous state, exposed on rocks, hilly lands, and arid situations, being at all times fully exposed to the sun: still, with us, we find that they thrive best with a partial shade, though we have frequently seen them doing well when fully exposed to the influence of the sun; but where they are tc be kept out of doors all the season, be careful in choosing for them an airy situation, and never allow the pots to become saturated with moisture. The habits of the Epiphyllum tribe are entirely different ; they are generally parasites, growing on the branches and about the roots of decayed trees ; consequently, they are often much shaded, and they evidently show it, for they still de- light to be shaded from the direct rays of a noonday sun. If they are kept in the house through the summer months, take some whiting, and make a thin white-wash, and put it on the inside of the glass, which will be found an agreeable and effectual shade ; but where time and means are at hand, a thin awning, of gauze or muslin, is preferable, provided it is regularly rolled up when the sun is not powerful. JUNE AND JULY. As the plants of the hot-house are all exposed to the open air, the directions will include both months. If the repot- ting is over, as recommended last month, all the attention they will require until the end of August is, the administer- ing of water at the roots, and by the syringe overhead. It will be impossible to say how great are their wants, these de- pending entirely upon the nature of the plant, the situation, and the season; but never neglect to look over them every evening, and after dry nights they will need a fresh supply in the morning, observing to give to none except they are be- eoming a little dry. Make weekly examinations for insects 180 HOT-HOUSE—OF PAINTING, ETC. [August. of any description, and when they appear, have them instantly destroyed. Always after heavy rains look over the pots, in case wate1 should be standing in them, which would injure the roots. Where any is found, turn the pot on its side, and, in a few hours, examine the draining which is defective ; small pots in continued rains should be turned likewise. Tie up all plants and shoots to prevent them from being destroyed by the wind, and be attentive to pick all weeds from the pots. Turn round all the plants occasionally, to prevent them from being drawn to one side by the sun or light. AUGUST. THE plants of the hot-house that were repotted in May and June, according to the directions therein given, will, at pre- sent, be in an excellent state of health, provided they have got at all times the requisite supplies of watering. And as we already have been very explicit on that subject, more re- marks now would be merely repetition. REPOTTING. If any of the repottings were neglected during May or June, let it be done about the first of this month. Let young plants that are growing freely, where the roots have filled the pots, and the plants required to grow, have pots one size larger. In turning out the ball of earth, keep it entire, not disturbing any of the roots. OF PAINTING, REPAIRING, AND CLEANSING THE HOUSE The necessary repairs of the hot-house are too often put off to the last day or week; and then with hurry are superfi- elally attended to Previous to the first of September, have September.] HOT-HOUSE—OF TAKING IN LfHE PLANTS. 181 all the wood-work painted (which ought to have one coat every two years), and the glass all neatly repaired. Have the flues and furnace examined ; plaster over all rents, and make good every deficiency. Give the flue a thick coat of lime white- wash. Have the walls, shelves, and staging properly painted. If there is a tan-bed, have that renewed; take out what is most decayed, using two-thirds new tan, which must be dried at least three days in the sun before it is housed, and carefully protect it from rains. SEPTEMBER. DRESSING THE PLANTS. Havina last month put the house in complete ordex all that remains necessary to be attended to is the state of che plants and pots, which should be regularly examined; «nd of those where the roots fill the soil, a little may be taken off the top, supplying its place with fresh earth, thereby giving what is called a top-dressing. Give each that requires 1t a sufficient rod, tying the plant neatly thereto; minutely scruti- uize each for insects, and where they are detected, have them eradicated. Finally, wash all contracted foulness from off the pots, at the same time pick off any decayed leaves ; thus all will be in perfect order to take into the house. If any plants have been kept in the hot-house during summer, they must likewise go through the same operation. OF TAKING IN THE PLANTS. From the 16th to the 24th, according to the season, is the proper time to take in the hot-house plants.

Europea latifolia is chiefly cultivated in Spain. The fruit is larger than that of Italy, but the oil is not so pleasant, which is obtained by crushing the fruit to a paste, and pressing it through a woollen bag, adding hot water as long as any oil is yielded. The oil is then skimmed off the water, and put into barrels, bottles, &e., for use. The tree seldom exceeds thirty feet, and is a branchy, glaucous evergreen, and is said to be of great longevity.

Leaves are elliptic, lanceolate, and a little serrated; flowers white in lateral bunches. It is subject to the small white scaly insect, and ought to be care- fully kept from them by washing. O. résea has pink flowers. O. paniculata is also a fine species. They are all very easily cultivated. (Soil No. 11.)

Several of them are both beautiful and profuse in bloom, especially P. Kermdsine, P. princéps, P. hybrida, P. fragrans, P. Newmannia, P. Lemo- chentziana, and are a very distinct species; the former is of a beautiful rosy crimson colour. (Soil No. 15.) Pelargoniums, Stork’s Bill. This genus, so universally known among us as Gerdnium, from which it was separated many years ago, is a family of. great extent and variety, for which we are principally indebted to the Cape of Good Hope. There are many hundred species, with upwards of twelve hundred beautiful and well-marked varieties, which have been obtained from seed. They are of every character, colour, and shade, of the most vivid description. The easy cultivation of the Pelargonium tribe, or Gerdniums, as they are commonly called, has rendered them very popular ; also the agreeableness of scent and fragrance, of which many of them are possessed, makes them favourites. Their flowering season is also of considerable duration, espe- cially the bright scarlet and crimson varieties, which bloom from March till August, rendering them quite indispensable in collections. Some growers complain of their straggling habits; but it is only those that do not know how to prune them: even some of the choice kinds of the present day could not be made to grow irregu.asly—such as Ajax, Forget-me-not, Ps March.] GREEN-HOUSE—REPOTTING. 247 Orion, Virgin Queen, and others; indeed, within these few years, the habits and beauties of the plant are improved a hundred fold, and those who are only acquainted with the old sorts would be transported with a view of the dazzling and beauteous colony of the new kinds that have been procured by hybridizing those of good habit and character. The best method to adopt in impregnating these is to choose the female, one that has large flowers, of easy cultivation, and as nearly allied in character and other habits as possible. When a flower of the intended female is newly expanded, take a pair of very fine-pointed scissors, and cut off the anthers before the pollen expands; then, as soon as the summit of the style divides, apply the pollen taken from the anthers of the intended male plant on a very fine camel hair- pencil, or cut out the stigma entirely, and place the anther on the summit of the style, which, if correctly done, will have the desired effect. As soon as the seed is ripe sow it in light sandy soil; and when it has come up, take care not to over- water the soil, which would cause them to damp off. When they are about one inch high, put them into small pots, and treat as the other varieties. Have them all distinctly marked until they flower, which will be in the second year from the time of sowing. The tuberous and fleshy stemmed species are very interest- ing to the discriminating inquirer. Their habit and constitu- tion are so peculiar that we have frequently wondered that they have not been separated into distinct genera. The cul- tivation of them is more difficult, water being very prejudi- cial to them when they are inactive. If they are well managed, they flower beautifully, and the colours are very superior and peculiar, having frequently bright green and purple in the same flower.

Ivy leaved, white, Apple scented, Lemon scented, Bicolor, Nutmeg scented, Blanfordianum, Rose scented, &e. Comptonianum, There are several others very recently introduced, which have not bloomed so as to allow us to judge of their merits; but their foreign characters are highly flattering. The re- potting of the geranium tribe should be done as early in the month as possible, or even about the end of last month would be advisable in some seasons. (Soil No. 12, with a little more manure. ) Phérmium ténax, New Zealand flax lily, the only species ; foliage resembling an Jris, and very thready. In New Zea- land and Norfolk Island the natives manufacture from this plant a kind of stuff like coarse linen, cordage, &c.; the plant is very hardy, and we would be nowise surprised to see it stand the severity of our winters. It bears exposure to the open air in Kurope in the fifty-sixth degree of north latitude. The flowers are said to be yellow and lily-like; of the easiest cul- ture. (Soil No. 7.) Phylicas, above twenty-five species. Several of them are very pretty-growing evergreen shrubs, and of easy culture, P. horizontdlis, P. squarrésa, P. imbricata, P. myrtifolia, P. callosa, P. bicolor, and P. ericotdes, are all neat-growing ; flowers small white, in heads: drain the pots well, and keep them in an airy situation. The foliage of several of the species is downy. (Soil No. 6.) Phasedlus caracdlla, or snail flower, is a very curious _ blooming plant, with flowers of a greenish yellow, all spirally twisted, in great profusion when the plant is well grown. (Soil No. 12.) Phenix dactylifera, common date palm; a plant that attains a large size and of rather a rugged appearance; its fruit is the common well-known date. (Soil No. 12.) Pimileas, about fourteen species. Most of them are highly esteemed, and are not often seen in our collections. P. decussdta is the finest of the genus, both in foliage and flowers, which are red, and in large terminal clusters. P. his- pida, P. rosea, P. “inifolia, P. spicata, and P. spectabilis, are 250 GREEN-HOUSE—REPOTTING. [ March. all fine species. The latter has very beautiful lanceolate foliage and of an elegant habit. They should be well drained. They are very small evergreen shrubs, with white, red, or pink flowers. (Soil No. 6.) Pistacias, seven species of trees, principally of the south of Kurope. There is nothing particular in their appearance, except their productions in their native country. P. terebin- thus is deciduous, and produces the Cyprus turpentine. P. lentiscus is the true mastich tree, which is obtained by cutting transverse incisions in the bark. /P. vera, P. reticuldta are good species; leaves pinnated; leaflets ovate, lanceolate ; easily cultivated. (Soil No. 2.) Pitidsporums, about nine species, sail handsome foliage, and small white flowers in clusters, which are fragrant. P. tobira is a native of China, and nearly hardy; leaves lucid, obovate, obtuse, and smooth; there is a beautiful variegated variety of it. P. unduldtum, P. coridceum, P. revolitum, P. filvum, and P. ferrugineum are very ornamental ever- greens, and will grow with the most simple treatment. (Soil No. 13.) Platylobiums, Flat Pea, four species of fine free-flowering plants, flowers leguminose; colour yellow. P. formodsum, P. ovdtum and P. trianguldre are the best; the foliage of the former two is cordate ovate; the latter hastate, with spiny angles. (Soil No. 6.) Plumbagos, Lead-wort. The two most beautiful species for green-house culture are P. capensis, of a beautiful light blue, flowering in spikes from June to December ; foliage pale green, oblong, entire, and glaucous—P. Larpanta, Lady Larpant’s Leadwort, is of a very dwarf habit, small dark greenish-brown foliage, crowned with flowers of the finest azure blue, and is tolerably hardy in the open ground; in fact, they are both perfectly hardy in the Southern States. (Soil No. 1.) Podalyrias, about fourteen species of pretty Cape sbrubs; foliage oblong, obovate, and silky-like; the flowers legumi- nose; colour blue or pink. VP. sericea, P. styracifolia, P. coriscans, P. argentea, P. lipariotdes, and P. subiflora, are the finest and most distinct species, and flower abundantly. (Soil No. 6.) Proieas, about forty-four species. The foliage of this genus is very diversified: flowers very large, terminal ; stamens Con, me RP March. GREEN-HOUSE—-REPOTTING. 251 protected by an involucrum, many-leaved and imbricated ; which is very persistent. P. cynarotdes has the largest flower, which is purple, green, and red. P. speciosa, P. wm- ponalis, once P. longifolia, P. melaleuca, P. grandiflora, P. cocctneu, P. cenocdrpa, P. pallens, P. formosa, P. magnifica, P. speciosa rubra, and P. mellifera, will afford a very good variety. It is almost impossible to describe their true colour, it being so various; red, white, straw, brown, green, and pur- ple, are most predominant, and frequently to be seen in the same flower. The plants must be well drained; and during warm weather be careful that they are not neglected in water, for if they are suffered to droop, they seldom recover. For this reason the pots ought not to stand in the strong sun; the plants can bear it, but to the roots it is injurious. (Soil No. 9.) Pultneas, about forty species, pretty little dwarf-growing shrubs of New South Wales; flowers, small, leguminose, all yellow with a little red outside of the petals. P. subumbel- lata, P. villosa, P. obcordata, P. argéntea, P. plumosa, P flexilis, shining-leaved, fragrant; P. candida, and P. stricta, are all fine species, and esteemed in collections. The leaves are all small; they require an airy exposure, and the pots drained. (Soil No. 6.) Rhodochiton volubile, or Lophorspérmum rhodochiton : this is a very fine climbing plant, with large tubular dark brown flowers, blooming from July to October ; it is of rapid growth, and is an excellent plant for the flower-garden. The plant must have frequent repotting to make it grow rapidly, for the finer it grows the more profusely it flowers. (Soil No. 12.) Rhododéndrons (Rose tree), a magnificent genus, and con- tains some of the most superb and gigantic plants that adorn the green-house. At present the most admired is R. arboreum, with its varieties. It has deep crimson flowers, with dark spots and flakes campanulated, and in large clusters; leaves lanceolate, acute, rough and silvery beneath. FR. arboreum album is very rare. Lt. arboreum superbum, flowers same shape as arborewm, colour bright rosy scarlet; foliage one- third larger, but not silvery beneath; grows freely, and gene- rally thought the finest variety. 2. arborea alta- Clarence is also very superb, LR. arborea, Russelidnum, pictum, venistum, guttdtum, tigrinum, noblednum, grandiflorum, spectabile, are all very distinct; but there are so many other varieties from eS 252 GREEN-ILOUSE—REPOTTING [March seed that they will soon be so much amalgamated that the named sorts will not be distinguished. A green-house with- out some of the choice varieties of this plant is deficient of a flower whose beauty and grandeur are beyond the highest imagination. It is a native of Nepaul, in India, and when found by Dr. Wallach, awakened the ambition of every culti- vator and connoisseur in Europe.* There are several other species lately brought from that country, which are highly valued: the species are R. campanulatum, R. anthopogon, and R. cinnamomum. They are rarely seen in our collections. There is also another new addition to this already majestic family, discovered by Doctor Hooker, in the Himalaya Moun- tains, which for gorgeous splendour is supposed will surpass all their predecessors; the foliage of many of them are cer- tainly distinct and unique in all its parts. We have also a brilliant yellow species, KR. javanicum, from Japan; it is novel and beautiful, blooming when the plants are only about a foot high—an indispensable sort. The pots should be well drained, and if they are large, put several pieces of sandy stone or potshreds around the side, for the fine fibres delight to twine about such, being mountainous plants. When grow- ing, give copious waterings at the root. For young plants, soil No. 6. And for blooming plants use one portion of leaf mould. Roéllas, pretty leafy shrubs, with blue terminal funnel- shaped flowers, lip-spreading; &. cilidta, R. spicata, and R. pedunculdta are the finest of the genus. The pots must be well drained, and care taken that they are not over-watered. (Soil No. 6.) Sdlvia (Sage) is an extensive genus of soft-wooded, shrub by, or herbaceous plants; very few of them do well in the green-house, and many of them are very trifling, having no other attraction than the flower; and those of the tender species, when compared with S. fdélgens, crimson, S. splén- dens, scarlet, S. angust/félia, pale blue, S. pdtens, dark blue, S. involucrata, pink (which in artificial climates constitute the standard of the genus), are not worth cultivation. The best method to adopt with the summer flowering kinds is to plant them in the garden in May: they will grow strong and * Mr. Hogg, the eminent horticulturist of New York, raised the first plant of arboreum from seed in England.

They neither grow nor flower so well as when planted out, and even a slip planted in the ground in moist weather will root in a few days, grow, and flower in a few weeks. WS. spléndens is the best to select for the purpose. All will grow easily with encouragement. (Soil No. 12.) Scottias, three species of valuable plants; S. dentdta, with rosy leguminose blossoms; leaves opposite, ovate, acuminate, serrate; S. angustifolia, has brown flowers; S. trapezifor- mus, leaves ovate, acute, serrulate. We do not know the colour of its flowers ; the pots must be well drained, and the plants kept in the warmest part of the green-house, and near the light. (Soil No. 6.) Seneécios. Some species of this genus are pestiferous weeds all over th: world. They are even found near the limits of perpetual snow, where neither tree nor shrub is able to rear its head, and yet there are a few species that are neat little plants, and are worthy of a situation, namely, S. grand/flo- rus, S. venistus, and WS. cinerdscens, with the double white, purple, and red variety of S. élegans. The last three varie- ties are free flowering, but if allowed to grow several years, they become unsightly. Being very easily propagated, a few cuttings of them should be put in in September, and in two weeks they will strike root, when they may be put in pots to keep through the winter, and then planted in the garden, con- tinuing to renew them. ‘The other mentioned species should be frequently done the same way. Do not keep them damp during winter, or they will rot off. Give them an airy expo- sure. (Soil No. 12.) Sollya heterophylla: a good climbing plant, with bright blue clusters of drooping flowers; it is a native of New Hol- land, and will prove a hardy plant south of latitude 36° (Soil No. 4.) Sparrmdnnias are strong-growing green-house shrubs. _S. Africdna is a plant very common in our -collections, with large three-lobed cordate leaves, hairs on both sides; flowers from March to July. S. rugésa. The leaves are rugged; flowers of both are white, in a kind of corymb, supported by a long footstalk; buds drooping, flowers erect. ‘There is a plant known in our collections as the free flowering Sparr- mdnnia (which is Hntélia arboréscens), and is easily distin- 22 254 GREEN-HOUSE—REPOTTING.

(Soil No. 12.) Spherolobiums, only two species of leafless plants, with yellow and red leguminose flowers, which proceed from the young shoots. S. vimineum and S. medium. They flower freely, and are easily cultivated. The old wood should be frequently cut out where it is practicable. Drain the pots. (Soil No. 6.) Sprengélia incarnata, the only species, a very pretty plant, allied to Epdcris; foliage acuminate, embracing the stem ; flowers small, pink, bearded, and in close spikes; grows freely. The pots must be well drained, and the plants, when dormant, watered sparingly; for if they get sodden about the roots, they very seldom recover. (Soil No. 6.) Strelitzia, or queen plant: a genus of fine plants belonging to the natural order of Musacea. WS. regina, S. ovdta, and S. humilis are the most free and beautiful flowering species, and are very similar, except in habit. The flower-stalk is from one to two feet long, producing about five flowers of a bright yellow, having a large blue stigma, which forms a dis- tinct contrast. WS. jéncea and SN. parviflora are also desirable species, but are more rare than the former, which ought to be in every green-house. (Soil No. 19.) Streptocarpus rhéxit, a free-blooming dwarf plant, of easy culture in soil No. 4. Styphélias, seven species of very showy flowers, with mu- cronate leaves; corolla in long tubular form, having several bundles of hairs in it; segments reflex and bearded. S. tubiflora, crimson ; S. triflora, crimson and green; S. adscén- dens, and WS. longifléra, are beautiful species. They grow freely, and should be well drained, as too much water is very hurtful to them. In summer, they ought not to be much ex- posed to the hot sun, or the foliage will become brown. (Soil No. 6.) Sutherlandia frutéscens, very similar to Swainsdnia ; flowers fine scarlet. (Soil No. 2.) Swainsonias, four species of free-flowering, soft-wooded shrubs, natives of New South Wales. SS. galegifolia, S. coronillefolia, aud S. astragalifolia, are red, purple, and March.] GREEN-HOusSE—REPOTTING. 255 white; leguminose flowers in spikes from the axils, are of easy culture and deserving of a situation; the foliage is pin- nate; leaves ovate, acute. (Soil No. 2.) Tecoma is a genus of beautiful flowering plants, separated from Bignénia. They are of easy culture and desirable in all collections. 7. capénsis has bright orange flowers in large clusters, and very profuse on large plants. TZ. australis, known as Bignonia pandora, has white and pink flowers in great profusion. 7’. jasmindidvs is quite a new plant, produc- ing very large clusters of white flowers, with a bright pink centre; it is a charming plant for climbing, and the foliage is of a very agreeable shining green. The plants require en- couragement. (Soil No. 10.) Testudindria, Elephant’s foot, or Hottentot’s bread, two species remarkable for their appearance. The root or bulb, if it may be so called, is of a conical shape, and divided into transverse sections. Those of one foot diameter are computed to be one hundred and fifty years of age. It is a climbing herbaceous plant, with entire reniform leaves of no beauty ; flowers small; colour green. The pots must be well drained, for when the plant is inactive, it is in danger of suffering from moisture, and ought not to get any water. 7. elephdn- tipes and T. montana are the species, natives of the Cape of Good Hope, and require the warmest part of the house. (Soil No. 10.) Thea : a genus celebrated over the known world as furnish- ing the domestic drug called Teu. T. viridis, and 7. bohéa are said to be the species which supply the tea. Some have asserted that there is only one shrub used, but by examina- tion it may be easily perceived that there are leaves of various shape and texture, some of them similar to Camellia sesanqua. Dr. Abel gives an explicit detail of the growing and manu- facturing process of tea, from which, in compliment to our fair patrons, we give a few extracts: “The tea districts of China extend from the twenty-seventh to the thirty-first degree of north latitude. It seems to sue- ceed best on the sides of mountains. ‘The soil from which I collected the best specimens consisted chiefly of sandstone schistus, or granite. ‘The plants are raised from seeds sown where they are to remain. Three or more are dropped into a hole four or five inches deep; these come up without farther trouble, and require !i*‘'e culture, except that of removing 256 GREEN-HOUSE—REDPOTIING. [ March. weeds, till the plants are three years old. The more careful stir the soil, and some manure it, but the latter practice is seldom adopted. The third year the leaves are gathered, at three successive gatherings, in February, April, and June, and so on until the bushes become stunted or slow in their growth, which generally happens in from six to ten years. They are then cut in to encourage the production of fresh roots. “The gathering of the leaves is performed with care and selection. The leaves are plucked off one by one; at the first gathering only the unexpanded and tender are taken; at the second those that are of full growth; and at the third the coarsest. The first forms, what is called in Hurope, imperial tea; but, as to the other names by which tea is known, the Chinese know nothing; and the compounds and names are supposed to be made and given by the merchants at Canton, who, from the great number of varieties brought to them, have an ample opportunity of doing su. Formerly it was thought that green tea was gathered exclusively from 7. viridis ; but that now is doubtful, though it is certain that there is what is called the green tea district and black tea district ; and the varieties grown in the one district differ from those of the other. I was told by competent persons that either of the two plants will afford the black or green tea of the shops, but that the broad thin-leaved plant (7. viridis) is preferred for making the green tea. “The tea leaves being gathered, are cured in houses which contain from five to twenty small furnaces, about three feet high each, having at top a large flat iron pan. There is also a long low table covered with mats, on which the leaves are laid, and rolled by workmen, who sit around it: the iron pan being heated to a certain degree, by a little fire made in the furnace underneath, a few pounds of the fresh-gathered leaves are put upon the pan; the fresh and juicy leaves crack when they touch the pan, and it is the business of the operator to shift them as quickly as possible, with his bare hands, tilt they cannot be easily endured. At this instant he takes off the leaves with a kind of shovel resembling a fan, and pours them on the mats before the rollers, who, taking small quan- tities at a time, roll them in the palms of their hands in one direction, while others are fanning them, that they may coo! the more speedily, and retain their curl the longer. This pro: March. | GREEN-HOUSE—REPOTTING. 257 cvss is repeated two or three times, or oftener, before the tea is put into the stores, in order that all the moisture of the leaves may be thoroughly dissipated, and their curl more com- pletely preserved. On every repetition the pan is less heated, and the operation performed more closely and cautiously The tea is then separated into the different kinds, and depo- sited in the store for domestic use or exportation. “The different sorts of black and green arise not merely from soil, situation, or the age of the leaf; but after winnow- ing the tea, the leaves are taken up in succession as they fall ; those nearest the machine, being the heaviest, are the gun- powder tea; the light dust the worst, being chiefly used by the lower classes. That which is brought down to Canton then undergoes a second roasting, winnowing, packing, &c., and many hundred women are employed for these purposes.” Kzempfer asserts that a species of Caméllia as well as Olea Fragrans is used to give it a high flavour. Tacsonia, a genus of plants much resembling Passifloras, both in flower and habits. 7. pinnatistipulata and 7. mollis, when planted into the ground and trained up the rafters of the green-house, make a pretty appearance with their profu- sion of rosy blush-coloured flowers. (Soil No. 13.) Tropedlum, a genus of generally delicate-growing plants, principally from South America. They require nicety of treatment to bloom them well, unless a large bulb can be procured, when it may be planted’ in a seven-inch pot, and will then flower without farther care by training their delicate shoots on a wire trellis, or small twigs of branches stuck in the pots. 7. tricolorim, T. tricolorum supérbum, and T. pentaphyllum have beautiful scarlet flowers marked with yel- low and biack, and are superb and lovely when in bloom. 7 brachyseras has yellow flowers. (Soil No. 10.) Verbéna. The beauty of the green-house in spring and the flower-garden in summer is greatly augmented by the late introduction of this lovely family of perpetual flowering plants. There are among them every shade of colour, from the richest scarlet to the purest white, and in addition to the beauty and profusion of their flowers, several of them are ex: quisitely scented. V. chamedryfolia, or melindres, was the frst scarlet species introduced, and it is yet pretty. NO* 258 GREEN -HOUSE—REPOTTING. [ March. WHITES. RED. Americana, St. Marguirette, White F erfection.

In England, they bear the titled names of Ladies, Marquesses and Queens, commanding a very high price ; but with all their titles, none of them excel a few of those named above. They require very little water during winter, and should be kept on a dry airy shelf till February, when the pots may be enlarged, except those intended for the garden, which can be planted out about the middle of April.

The whole family should be industriously collected and cultivated; for truly we are not acquainted with a tribe of plants that will give as much satisfaction with as little cost and trouble: they naturally grow on hills and elevated plains,so that they must not be kept wet. (Soil No. 9.) Verdnica, an extensive genus of plants that are cultivated largely as ornaments for the flower-garden. Within these few years some very beautiful species have been discovered in New Zealand. Among them is V. specidsa, a picture of a plant with foliage equal to a Camellia, producing spikes about three inches long, of bright purple flowers, fading to a pale blush. V. Lindleyana, with ovate lanceolate leaves, and spikes of delicate blush flowers; blooming in winter. V Andersonii, spikes of flowers opening blue, and changing to white, in flower from August to Christmas. They are of the simplest culture—growing freely and symmetrically in soil Now: Vimindria denudata, the only species. This plant is re- markable for its twiggy appearance, but it has no foliage, ex- cept when growing from seed. It has at the extremity of the twigs or shoots an ovate, lanceolate leaf, disappearing when the plant grows old; the flowers are small, yellow, coming out of the young shoots, to the astonishment of the beholder. It grows freely. (Soil No. 6.) Vibirnums. A few of these are very ornamental evergreen shrubs, and almost hardy. V. ¢inus is the well-known Lau- restine (or what is commonly called Laurestinus), is of the easiest culture; flowers small, white, and in large flattened panicles; blooming from February to May, and universally esteemed. It will stand the winter by a little protection, but the flower-buds being formed in the fall, the intense frost destroys them; consequently, it will not flower finely, except it be protected from severe frost. V. dicidum is a good species, and superior in flower and foliage to the former, but does not flower so freely when the plants are small. When they grow large, they flower profusely. There is a desirable variegated variety. V. odoratissimum has smooth, evergreen, oblong elliptic, distinctly toothed leaves, and frequently a stripe in them, is sweet-scented, but not a free-flowerer. V. hirstitum has flowers similar to the above; foliage ovate, with rougk brown hairs on both sides, and “ery characteristic. V. série 260 GREEN-HOUSE—REPOTTING.

W. longifolia is similar; both have small silvery-white flowers, and are easily cultivated. (Soil No. 2.) Witsénias, four species. W. corymbosa is a plant that has stood in high estimation ever since it was known, but, unfor- tunately, there is a very inferior plant. Aristéa cyanea got into our collections under that name. ‘The panicles of W. corymbosa are quite smooth; those of Ar/stéa are hairy, which is itself sufficient to detect them; but otherwise the appear- ance of W. corymbdsa is much stronger and more erect grow- ing, not inclining to push at the rootsso much as Aristéa. The foliage is lanceolate and amplexicaule, the leaves having much the nature and appearance of Jris. The plant is of easy culture, and blooms from July to November ; colour fine blue. W. ramosa is a very fine species, similar to the above; flowers yellow and blue; plant branching. (Soil No. 8.) Yiicca aloefolia, and its beautiful variety variegata, are de- sirable plants. They do not bloom till they have grown to considerable size; but still they make a decided contrast among other plants; the flowers are white and produced ou terminal spikes. (Soil No. 11.) Zamias, about twenty species, eight of which belong to this compartment. The foliage is greatly admired, and is in large fronds, with oblique, lanceolate leaflets. Several of them glauceous. They bear heads of flowers of a brown colour in the centre of the plants, very like large pine cones. Z. hor. rida, the finest; Z. pingens, Z. sptralis, and Z. latifolia, are the most conspicuous. They must be kept in the warmest part of the green-house; and give them large well-drained pots, watering sparingly during winter. They are imported trom the Cape of Good Hope. (Soil No. 11.) All the plants herein named requiring to be drained, in pre- paring the pots, place first a piece of broken pot, oyster: shell, or any similar substitute, with the convex side on the hole of the pot, and then put in a few, or a handful (accord- ing to the size of the pot) of shivers of broken pots, or round grayel about the size of garden beans.

The roots must not be disturbed, but the ball turned out entire; and put as much earth as will raise the ball within about half an inch of the rim of the pot. Press the earth down around it with a thin narrow piece of wood, called a potting stick, frequently shaking it that no vacancy may be left. If the roots are rotten, or otherwise injured, take all such off. If this be the case, the plant wili be sickly. Give it a new pot of a smaller size, administering water moderately until there are visible signs of fresh growth. The plants must not be disturbed while flowering; let the re- potting be done afterward. Plants are, at certain stages, if in good health, in a state that no one can err in shifting them when desirous to hasten their growth. Those plants that make two or more growths during the summer may be repotted in the interim of any of these growths, and all others just be- fore they begin to push in the spring; that is, when the wood buds are perceptibly swelled. Never saturate with water fresh-potted plants. There are many kinds that, without in- jury, can be repotted when growing. When done potting, tie all up neatly with stakes rather higher than the plant, that the new shoots may be tied thereto during the summer, to prevent them from being destroyed by the wind. There may be many that do not require repotting, but would be benefited by a top-dressing. ‘This should be done by probing off all the sur- face earth down to the roots, replacing it with fresh compost, suitable to the nature of the plant. When the above is done, arrange all the plants in proper order, and syringe them clean; but if there are any of the green-fly, they must be fumigated previous to syringing. The pavement of the house should be cleanly and neatly swept every day, and washed at least once a week. Thus, every part of the house will be in order before the hurry of the garder commences. 262 GREEN-HOUSE—OF ENARCHING, ETc. [Murch OF ENARCHING OR GRAFTING BY APPROACH. In this method of grafting, the scion is not separated from the parent plant until it is firmly united with the stock; con- sequently, they must stand contiguously. We intend the following method to apply directly to Caméllias, as they are the principal plants in the green-house that are thus worked. The criterion for the operation is about the first of March or June. Place the stock contiguous to the plant where the graft or enarch is to be taken from. If the branches, where the intended union is to take place, do not grow at equal heights, a slight stage may be erected to elevate the lower pot. ‘Take the branch that is to be enarched (the wood of last year is the most proper), and bring it in contact with the stock; mark the parts where they are to unite, so as to form a pointed arch. In that part of the branch which is to rest against the stock, pare off the bark and part of the wood to about two or three inches in length, and in the side of the stock which is to receive the graft do the same, that the in- side rind of each may be exactly opposite, which is the first part where a union will take place. Bind them firndy and neatly together with strands of Russia matting, and protect the joint from the air by a coat of close composition ; clay of the consistency of thick paint, turpentine, or wax, will equally answer. Finish by fastening the grafted braach to the head of the stock or a rod. Many practitioneis make a slit or tongue into the enarch and stock, but we find it unnecersary, more tedious, and likewise more danger ia breaking. Camél- lias are also grafted and budded, buc these two operations re- quire great experience and continued attention, and seldom prove so successful as enarching. ‘When they have perfectly taken, which will be in from chree to four months, begin to separate them by cutting the scion a littie at three different periods, about a week apart, separating i¢ at the third time. If the head is intended to be vaken off the stock, do it in like raanner. By the above method, many kinds cau be grown on the same stock. The san. pian applies to alt evergreens. fy (op) G2 Aprii.} GREEN-HOUSE—WATERING. APRIL. ReGarpineG the shifting or repotting of plants, the direc. tions given last month may be followed. If the plants that require it are not shifted, get them done as soon as possible. Those that were repotted last month will have taken fresh root in the new soil, and the advantage will soon be per- ceptible. In order to strengthen the plants, and keep them from becoming drawn and spindly, admit large portions of air every mild day. Indeed, there will be very few days in this month that a little air may not be given, always observing to divide the quantity regularly over the house, in cool nights closing in time. About the end of the month an abundance of air is indispensable, leaving the sashes and doors open every mild night, that the plants may be inured to the open exposure they will have in a few weeks. WATERING. As the season advances and vegetation increases, the waterings will require to be more copious and more frequent. Look over all plants minutely every day, and with judicious care supply their wants. Those that are of a soft shrubby nature, and in a free-growing state, will require a larger portion at one time than those of a hard texture, which may only want it every two or three days. The weather and situation, in some instances, may require a modification of these diree- tions. Plants in general will not suffer soon from being a little dry as from being over-watered. The health and beauty of the foliage of the plants may be much improved by syring- ing them freely three evenings in the week, except in moist weather, when it ought not to be done. ‘The ravages of many insects also will be retarded, especially mildew and red spider, which will be entirely destroyed. If the red spider is on any of the plants particularly, take them aside evening and morn- ing, and give them a good dashing with water through the syringe. Where there is mildew, after syringing the plant, dust it on the affected parts with flower of sulphur, and set them for a few days where they will be sheltered from the 264 GREEN-HOUSE—ORANGES, ETC. [April wind, after which wash off the sulphur. If the cure is not complete renew the dose. Always sweep out and dry up the water in the house when any is spilt. The succulent plants will be in want of a little water about once a week, but do not over-water them, as there is not heat enough tc absorb much moisture. If the soil is damp, it is quite suff cient. ORANGES, LEMONS, ETC., Will, in many instances, about the end of this month, be showing flowers or flower-buds. They must, under these circumstances, have plenty of air to prevent them from fall- ing off when entirely exposed. The reason that we see so much fine blossom falling to the ground where the trees are brought out of the house in May, is from the confinement they have had. Where there isa convenience of giving air from the back of the green-house, it should always be given in mild days, especially in those houses that have a recess back from the top of the sashes, for even if the sashes are let down every day, still the house will not be properly ventilated. Any plants that are sickly and intended to be planted in the garden next month to renovate their growth, may be cut back Gf not already done) as far as is required to give the tree a handsome form, taking care not to cut below the graft of inoculation. Let the operation be done with a fine saw and sharp knife, smoothing the amputations that are made by the saw; and if they are large, put a little well-made clay over the wound, to prevent the air from injuring it. Beeswax and turpentine are preferable to clay, not being subject to crack or fall off by the weather. If there are any Lagerstreemias, Pomegranate, or LHy- drangeas in the cellar, they should be brought out about the first of the month, and planted in their respective situations. Give the Hydrangea a very shady spot. It does not require much sun, provided it has plenty of air, and do not plant it into soil that has been lately manured. A large plant must have great supplies of water in dry weather. If the plant is very thick, the oldest branches may be thinned out, but do not evt out any of the young shoots, as they contain the embrya of the flower. Lagerstramias will flower abundantly without April. | GREEN-HOUSE—GERANIUMS. 265 pruning, but, to have-fine large spikes of flowers, cut in the wood of last year to about three eyes from the wood of the preceding year; by this they will be much finer. Pome- granates will only require a little of the superfluous wood cut out. Perhaps some of them may be desired to flower in pot or tabs during summer ; the balls will admit of being much reduced, and by this a pot or tub very little larger will do for them. Do not give much water until they begin to grow MYRTLES AND OLEANDERS. If any of these have grown irregularly, and are not headed down or otherwise pruned, as directed last month, it should now be done. Oleanders are very subject to the white scaly insect, and, before the heat of summer begins, they should be completely cleansed. This insect is likewise found on Myriles, which are worse to clean, and ought to be minutely examined twice every year. We have observed the red spider on these shrubs, which makes the foliage brown and unsightly. If it is detected in time, syringing is an effectual remedy. GERANIUMS. These will now begin to flower, arid the sun will greatly deteriorate their rich colours where they are near the glass with a southern aspect. The glass should be whitewashed or covered with thin muslin, which will cast a light shade over them, and prolong the duratioa of the bloom; but if they are above five feet from the glass, shading is not re- quisite. The strong kinds will be growing very luxuriantly, and require liberal supplies of water. When syringing, do not sprinkle the flowers, as it would make the colours inter- mingle with each other, and cause them to decay prema- turely, If they have been properly attended to in that respect, it may be dispensed with after they have come in flower. Cape Bulbs. Those that flowered late in autumn, as soon as the foliage begins to decay, may be set aside, and the water withheld by degrees. When the foliage is en- tirely gone, and the roots dry, clear them from the earth, 9 “ 266 GREEN-HOUSE—INSKCTS. [Apru and after lying exposed in the shade for a few days to dry, pack them up in dry moss, with their respective names attached, until August, when they may be again potted. Treat those that are in flower the same as directed in last month. Dutch Roots. All the species and varieties of these that have been kept in the green-house during the winter will now be done flowering; the water should be withdrawn gradually from them; and then the pots turned on their sides to ripen the bulbs. Or, a superior method is, where there is the con- venience of a garden, to select a bed not much exposed. Turn the balls out of the pots and plant them; the roots will ripen better this way than any other. Have them correctly marked, that no error may take place. They can be lifted with the other garden bulbs. e FLOWERING PLANTS The best situation for most plants, while in flower, is where they are shaded from the sun, and fully exposed to the air. Primroses, both Huropean and Chinese, flower best, and the colours are finest, where the plants are in the front of the house and entirely shaded. The Chinese Azaleas and Rhododéndrons require, while in flower, a similar situa- tion. Have all the shoots tied naturally to neat rods, and keep them clear from others by elevating them on empty pots, or any other substitute. See that there are no insects upon them; for they make a miserable contrast with flowers. The Calla Avthiopica should stand in water when in bloom, and even before flowering they will be much strengthened by it. INSECTS. Insects will, on some plants, be very perplexing The weather may admit of those that are infected to be taken out of doors, and put into a frame in any way that is most convenient. Iumigating them about fifteen minutes, if the day is calm, will be sufficient; but if ‘windy, they will take half an hour. When done, syringe them well, and put them in their respective situations. By the above method Apriv.] GREEN-HOUSE—FI WERING STOCKS. 267 the hous will not be made disagreeable with the fumes of tobacco. Tie up neatly all the climbing plants. Keep those that are running up the rafters of the house close to the longi- tudinal wires. As previously observed, running plants should not be taken across the house, except in some instances where it can be done over the pathway, otherwise it shades the house too much. Clear off all decayed leaves and all contracted foulness, that the house and plants may in this month have an enlivening aspect, as it is undoubtedly one of the most in- teresting seasons of the year in the green-house. FLOWERING STOCKS. Those that have been kept in the green-house, or in frames, should be jp aah into beds or the borders, where they will seed better than if kept in the pots. The method generally adopted is, to select the plants that are intended for seed; plant the different kinds distinctly and separately ; then take a few double-flowering plants of each kind, which plant round their respective single varieties that are to be kept for seed. Whenever any of the colours sport, that-is, become spotted or striped with other colours, plant such by themselves, tor they will soon degenerate the whole, and ought never to be seen in collections that have any pretensions to purity. Many have been the plans recommended as the best for saving and grow- ing from seed the double varieties of German stock. In every method we have tried we have been successful and unsuccess- ful; although we generally practise planting the double kinds beside the single, where they are intended for seed. We have no scientific reason for it; not seeing what influence these monsters of flowers can have over a flower where the male and female organs are perfect; which in these are wanting. Some say that the semi-double sorts are best; we have like- wise found them both abortive and fruitful in the desired results. 268 GREEN-HOUSE—WATERING, ETC. [ May. MAY. Axcut the first of the month all the small half-hardy plants may be taken out of the green-house, and those that are left will be more benefited by a freer circulation of air, which will inure them to exposure. The Geraniums ought to stand per- fectly clear of other plants, while in flower and growing, or they will be much drawn and spindly. WATERING. We have advanced so much on this subject, another obser- vation is not necessary, except as to succulents, which are frequently over-watered about this period. Before they begin to grow, once a week is sufficient. OF BRINGING OUT THE GREEN-HOUSE PLANTS. Those trees or plants of Orange, Lemon, Myrtle, Nerium, &c., that were headed down with the intention of planting them into the garden, to renovate their growth, should be brought out and planted in the situations intended for them. A good light rich soil well do for either, and the balls of earth might bea little reduced, that when they are lifted, they might go into the same pot or tub, or perhaps a less one. This being done, the plants, generally in a calm day from the 12th to the 18th of the month, should be taken out, carrying them directly to a situation partially shaded from the sun, and protected from the wind. In regard to a situation best adapted for them during summer, see fot-house this month, which will equally apply to green-house plants. All Primroses and Polyanthus delight in shade. The reason of so many plants of the D. oddra* dying, is from the effects of the sun and water. We keep them always in the green-hgyse. * On examining these plants, when the first appearance of decay affected them, the decayed part was without exception at the surface of the soil, which was completely mortified, while the top and roots were apparently fresh. This led us to conclude that the cause was the effect of sun and water on the stem. We have since kept the REPOTTING PLANTS. 265 May. GREEN-HOUSE y The large trees may be fancifully set either in a spot for the purpose, or through the garden. Put bricks or pieces 9f wood under the tubs to prevent them from rotting, and strow: a little litter of any description over the surface of the soil to prevent evaporation, or about one inch of well-decayed ma- nure, which will, from the waterings, help to enrich the soil. A liberal supply of water two or three times a week is suffi- cient.
