The American Flower Garden Directory

Some, very injudiciously, in extreme frosts put into the room, where there is no chimney, amongst the plants, a furnace of charcoal, in order to heat the room. The effect is, that the foliage becomes dark brown, and hardened like, and many of the plants die, the rest not recovering until summer.

Watering may be attended to according to the directions of January, only observing that those that begin to grow will absorb a little more than those that are dormant.

Roses, especially the Daily, if kept in the house, will begin to show flower buds. Use means to kill the Green-fly that may attack them.

Hyacinths and other bulbs must have regular attendance in tying up, &c. Take care not to tie them too tight, leaving sufficiency of space for the stem to expand. Give those in the glasses their necessary supplies, and keep them all near the light. Never keep bulbous roots while growing under the shade of any other plant.

Camellias, with all their varied beauties, will, in this month, make a splendid show. Adhere to the directions given in the previous month, and so that new varieties may be obtained, (see Green-house, February, under the head of Camellia,) which directions are equally applicable here. When the flowers are full blown, and kept in a temperature between 34° and 44°, they will be perfect for the space of four, five, and frequently six weeks, and a good selection of healthy plants will continue to flower from December to April.

Be sure that there is air admitted at all favourable opportunities. Give a little every day that there is sunshine, if it is only for a few minutes.

Hot-House

MARCH

If 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 destructive character are preying upon them. Too much water at the root frequently causes the foliage to become yellow. It will add greatly to their general improvement, to syringe the whole twice or three times a week, observing to do it in the morning about sunrise; 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. These will have made fresh shoots, and 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 SHIFTING PLANTS

Those Alstrœmèrias that are growing freely, and in small pots, should be put into pots of a larger size. This genus of plants will not flower except they are encouraged with frequent shifting: they are all beautiful.

Green-House

MARCH

The plants in this compartment will begin to assume a different aspect, and air must be admitted every day if practicable, giving large portions in sunshine by the sashes regularly over all the house, opening those of the front a little, and likewise the doors in fine mild days. To perform this judiciously, give a little about eight or nine o'clock, more at ten, and the whole from eleven till twelve o'clock, shutting again by degrees.

Fire heat will now be dispensed with, but in frosty nights have the shutters on about sundown. The sun is now powerful, and the house can be early shut up in the afternoon, and will gain as much natural heat as will keep up the required temperature, viz. 36° to 40°. Perhaps there may be uncommonly cold weather; at such times be attentive to ward off danger by applying artificial heat.

OF WATERING

Look over the pots and tubs at least every alternate day, to see where water is wanted. In watering, too much caution cannot be used, especially during winter and the commencement of spring. It was observed last month what would be the effect of too much water. It may be remarked, that if the exterior of the pot is very damp, the soil inside is too wet, and in that state is uncongenial to vegetation, which now begins to start, and ought by all possible means to be encouraged. People may be frequently observed watering all plants indiscriminately, not taking the trouble to look into or feel the state of the soil in the pots or tubs, and by going over them three or four times in this manner will be sufficient to put the plants in such a state, that they will not be recruited for some months. Hence the reason of so many sickly plants.

Caméllias, where there are collections, will continue to flower. Treat them according to the directions given last month.

OF ORANGES, LEMONS, &c

Be sure they are not too wet, as too much humidity as well as aridity causes their foliage to have a yellow appearance, with this difference, that in the former case the foliage is the same to the touch as when green; but in the latter, it is soft and dry. We have observed trees in tubs and half barrels, with holes all round their sides. This is a ludicrous idea, having the appearance of keeping the water from reaching the bottom of the tub or barrel. For the best kind of tub for large trees, see August under this head. If any of the trees have stunted, straggling, or irregular heads, about the end of this month, or beginning of next, head or cut them down to the shape desired. The old wood will push fresh shoots. You may cut close, or shorten less or more, according as you desire young shoots to arise; at the same time observe that you do not cut below the graft or inoculation. Trees thus headed down should be kept until May, and then planted in the garden, (see May,) or if that cannot be done, turn it out, and reduce the ball of earth by probing with a pointed stick all round the sides and bottom of the ball, cutting off any very matted roots. If any of the roots are decayed, cut them into the sound wood. By being thus reduced, it will go into the same pot or tub if not a less one. Having a good supply of fresh earth ready, put a few inches in the bottom of the pot or tub, place the tree therein, and fill all round, at the same time pressing it down with the hand or a stick. Give very little water until there are signs of vegetation.

MYRTLES, OLEANDERS, &c

These, with similar exotics, may be treated as above. If any of them have been infected with the scaly insect, after heading down, &c. scrub the remaining stems with a strong decoction of tobacco, heated to about 100°. Afterwards clean with soap and water.

GERANIUMS

These will be growing freely. Keep them in airy situations, so that they may not grow too weak, and flower imperfect. To flower these plants strong, and of good colour, they must not be too crowded together, neither far from the light, and have plenty of air admitted to them, when the weather is favourable. Keep them free from the Green-fly by fumigating frequently.

HERBACEOUS PLANTS

Plants of this character will, by the first of the month, begin to grow. The best time to divide and fresh pot them is when the young shoots are about one inch above ground. See under the head Shifting in this month.

OF CAPE BULBS, &c

Cape Bulbs, such as Lachenàlias, Oxalis, Ixias, Gladìolus, Watsònias, Babiànas, &c. will in many of the species be showing flower. Keep all of them near the glass, to prevent them from being weak and unsightly.

Hyacinths, Tulips, Narcissus, &c. Those that have been kept in the Green-house during winter will be in great perfection. Have all the flower stems tied up neatly to small stakes, (which, if painted green, will look much better,) and keep them from the direct rays of the sun. In the front of the house perhaps will be the best situation. They must be freely watered while in flower. Where there is convenience, it will be essential to keep the pots in saucers containing water; it will strengthen both stems and flowers, and likewise preserve them longer in perfection. Those that are blooming should be put aside, and watered sparingly, until the foliage begins to decay, when the pots may be laid on their side to ripen the bulbs.

REPOTTING

If you have any of the following plants that you are desirous of encouraging, they should be repotted this or next month at the latest. Large plants will not require it, if they were done in August. Pots one size larger than those that they are in, are sufficient. Acacias and Mimòsas being now united into one genus, there are above two hundred species. About one hundred and thirty belong to the Green-house. Amongst such a beautiful family, both for elegance of flower and beauty of foliage, it will be difficult to specify the most handsome and desirable for this department. A. móllis, A. glaucéscens, A. verticilàta, A. florabúnda, A. diffùsa, A. armàta, A. verniciflùa, A. decúrrens, A. armàta– weeping variety, A. púbescens, A. leucolòbia, A. decípiens, A. fragràns, A. pulchélla, A. lophántha, A. myrtifòlia, &c. These will afford a great variety of foliage, and are very desirable, flowering principally in winter, or early in spring. The flowers of those belonging to the Green-house are of a yellow or straw colour; the most of those that are red or purple, with the celebrated medicinal species, belong to the Hot-house, for which see May. There are some of the species very subject to the white scaly insect, which must be attended to, that they may not get to any extent.

Agapánthus, three species. They are all blue flowers. A. umbellàtus is very celebrated, and well known in the collections of the country. There is a variegated variety of it highly desirable, the foliage being white striped, and frequently the flower stem and the flower are as good as the species. They have very strong roots, and require plenty of freedom. Plants are always large before they flower, and when the pots, by frequent shifting, become inconvenient, the plant should be divested of all the earth, and, if too large, divide it, cutting off the strongest of the fibres; then they will admit of being put into smaller pots. If the above operation is performed in August or September, it will not retard their flowering, which, when well grown, is very handsome, the flower stem arising about three feet, and crowned with twenty or thirty brilliant blue blossoms, continuing to bloom successively.

Alonsòas, five species, all soft wooded, small, shrubby plants, with scarlet flowers. A. incisifòlia is known amongst us under the name of Hemímeris urticifólia, and A. lineàris as H. lineàris. If well treated, they form very handsome plants, and flower freely. They will not bear strong fumigation; and, when the house is under that operation, they must be put on the floor of the Green-house, where they will not be so much affected. They flower from May to August.

Aùcuba japónica is the only species. The flowers are small and almost insignificant, colour purple; but the foliage is a desirable object, being yellow spotted, or blotched. It is tolerably hardy, and withstands our winters. It prefers shade, and, if the situation was such when planted out, it would grow more freely. The hot rays of the sun are very prejudicial to its growth. It is an evergreen shrub, and very desirable.

Anagyris, three species, evergreen, pea flowered shrubs, flowers yellow, nothing very attractive in either of the species. A. fœtida is found in many collections, and we have no doubt but it may prove, in this country, a hardy shrub.

Azàleas, seven of the China species, which are those we shall enumerate here. The one that has been longest known in the collections of this country is A. índica, a most splendid shrub, with scarlet cup flowers and dark spots. A. índica àlba, flowers of the purest white, and rather larger than the former. A. índica purpùrea pleno, double purple. This variety is not so fine as any of the others. Properly it is not purple, or, if it may be termed so, the colour is very light; the flower irregular. A. índica phœnícea is magnificent. The colour is darker, and the flower larger than A. índica, and a free grower. A. sinénse, flowers large, yellow. The wood is much stronger than any of those previously mentioned. It bears a very high character in Europe. It has not yet flowered in our collection, but appears as if it would in the ensuing season (1832). All the above ought to have a situation in every Green-house. They flower from March until May. There are two other varieties which have not come under our observation. Do not shift or repot them, if they are in flower, until the flowering is over. The pots must be well drained; and the plants require a shaded situation. If they are properly treated, they will be completely covered with their showy flowers every year.

Aòtus, two species, both fine leguminose plants. A. villòsa, is a native of Van Dieman's Land; and A. virgàta, is from New Holland. The former is preferable. Both have yellow flowers, and are small evergreen shrubs.

Andersónia sprengelioídes, is the only species, and closely allied to Epácris, flowers small, and of a pale yellow colour. Drain the pots well; flowers from March to August.

Arbutus, eight exotic species, and six varieties. They are generally hardy in England; but we question if they stand out in the middle states. A. unìdo rùbra has the finest crimson flowers; A. serratifólia, the largest panicles; and A. Andráchne, the finest foliage. They flower in nodding panicles; the flowers are principally white, tinged with green, and wax-like. They bear a pretty fruit similar to a strawberry; hence it is called strawberry tree, and the fruit will remain on the bush a long time. They are very fine evergreens, and if any of them become acclimated, they will be a great acquisition to our gardens.

Bánksias. There are about thirty-two species, all curious in flower, and handsome and various in foliage; flowers in large heads and cone-shaped anthers, mostly green, and continue a considerable time in flower; produces a cone in shape of a pine, but not imbricate. The substance is as hard as bone, and contains many seeds. A cone of B. grándis in our possession weighs one pound twelve ounces, and contains about 107 seeds. Those most admired for the foliage are B. dentata, B. æmula, B. serràta, B. latifòlia, B. grándis, which is the largest. B. speciòsa has the longest foliage. B. Cunninghámii, B. spinulòsa, B. palludòsa, and B. rèpens, these will afford a good variety. B. verticillàta is entirely different in appearance from the others.

They should be well drained, and placed in an airy part of the Green-house. Great care should be taken that they do not get too dry, for they seldom recover if allowed to flag for want of water. This genus is named in honour of Sir Joseph Banks, a distinguished promoter of the study of natural history.

Bignònias. Those of this genus belonging to the Green-house have been divided to Tecòma, and there are only three for this department. T. austràlis known as B. Pandòræ; T. grandiflòra, known as B. grandiflòra, and has large and magnificent clusters of orange-coloured flowers, flowering from May to October.

Tecòma capénsis is a very pretty climbing shrub, a free grower, and flowers abundantly; flowers in dense panicles, colour orange and red, continues for several weeks in succession from April to August, greatly esteemed in Europe where it is known; being now in a few of our collections, will soon be generally admired.

Blètia hyacinthìna is the only species belonging to the Green-house, once known as Cymbídium hyacinthìnum. It is herbaceous, and when it begins to grow divide the root, putting the best into five inch pots. The spike of flowers are hyacinth-like, and of a beautiful purple, flowering from April to July.

Borònia is a beautiful genus of New Holland plants, contains about nine species; most of them have been universally admired; the flowers are star-like, and rose-coloured, and some of them sweet-scented. B. pinnàta grows and flowers freely. B. serrulàta, foliage serrated and very crowded, bearing the flowers on the extremity of the shoot. B. alàta has a fine appearance, and grows handsomely. The foliage is winged and pinnate, of a hardy nature, and easy culture, flowers freely. They are in flower about April and May, and continue a considerable time; are subject to mildew if not frequently syringed; drain the pots well.

Bouvárdias, two species. B. triphylla is well known amongst us, has brilliant scarlet flowers, and when well grown, will flower beautifully from May till September. To keep the plants, they should be frequently renewed; otherwise they are liable to grow straggling, and become subject to the small white scaly insect. B. Jacquìnæ we suspect has got confounded with the former, being very little different, except the foliage, which is more pointed. They flower from the young wood, and often throw their foliage in winter.

Brachysèmas, two species, both evergreen climbers. B. latifòlium has the best foliage, and large purple leguminose flowers. B. undulàtum, flowers yellow, and more plentiful than the former, continuing in long successions. The pots require to be well drained; very few plants of either in the country.

Burchéllias, two species. B. capénsis is a beautiful dwarf evergreen shrub, with tubular scarlet flowers in large terminate clusters; when well treated, grows and flowers freely, and highly deserving of attention. B. parviflòra differs from the above in the flowers being smaller and paler, and the foliage more pointed.

Beaufórtias, only two species. B. decussàta is splendid; the flowers come out of the wood with stamens in fine parcels, colour bright scarlet, foliage decussate, oval, and many-nerved, bloom persistent, and much esteemed. B. spársa, in flower similar to the other, colour light pink, foliage scattered, both easy of culture, and flower abundantly.

Brùnias, about ten species, have heath-like foliage, very fine, generally, on close observation, found to be three cornered. The flowers are white and globular, the plants when young are very handsome; the finest are B. nodiflòra, B. lanuginósa, B. comòsa, B. abrotanoídes, and B. formòsa. They require an airy situation, and in summer to be protected from the powerful rays of the sun. Drain the pots well.

Bósea yervamóra, Golden rod tree, leaves large, alternate, ovate, acute, with purple veins and nerves, flowers brown, in axillary dense panicles, grows strong and freely.

Bæckias, above twelve species, of heath-like appearance, and except for variety, are not otherwise desirable. B. camphoràta is camphor-scented; B. pulchélla is very neat; and B. virgàta flowers freely. Pots should be well drained. The flowers of all the genus are white.

Billardiéras, about five species, are desirable as climbers, being of rapid growth, and abundant in flower. B. longiflòra, fruits freely, and has fine blue berries which look handsome. B. mutábilis is changeable from purple to scarlet. The fruit of B. scàndens is covered with down, flowers straw coloured. B. fusifórmis differs in colour from the others, the flowers being blue. They require to be well drained.

Calceolàrias, about fourteen species, besides many hybrid varieties. C. angustifòlia, and C. integrifòlia are the best of the shrubby species. C. plantagínea, C. corymbósa, C. purpùrea, and C. hopiána, and of the hybrid varieties, C. micàns and C. hybrìda are very fine; but we understand they are numerous, and some of them very splendid.

To grow any of these properly, they should be divided a few weeks after they begin to grow; put them in small pots at first, and enlarge them gradually. Where there is a hot-house, after dividing them, it will greatly promote their growth to keep them in it a few weeks near the glass, until the weather gets mild, when they may be removed to the Green-house. The flowers are principally yellow. C. Fothergíllii, purpùrea, and archnoidea are purple; the hybrids are spotted with red and brown, and some of them streaked many colours. They continue a long time in flower.

Calothámnus, four species. This genus is named in allusion to the splendid appearance of the branches, covered with scarlet flowers of curious construction, which come out of the old wood. All the species are of easy culture, and very like dwarf pines. C. quadríffida has the largest flowers; C. claváta the most abundant. They are all evergreens, and flower from April to November.

Caméllias. There are about nine species, celebrated over the known world as furnishing the domestic drug called tea, in universal use, besides many flowering trees and shrubs as universally admired. Oil may be expressed from the seeds of all the species, and used as that of hemp and poppy in cookery. C. víridis and C. bohèa are said to be the species which supply the tea. Some have asserted that there is only one shrub used, but by examination it may be easily perceived that there are leaves of various shape and texture, some of them similar to C. sasanqua. Dr. Abel gives an explicit detail of the growing and manufacturing 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 succeed best on the sides of mountains. The soils from which I collected the best specimens consisted chiefly of sand-stone, 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 further trouble, and require little culture, except that of removing 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 full grown; and at the third the coarsest. The first forms what is called in Europe 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 so. Formerly it was thought that green tea was gathered exclusively from C. víridis; but that is now 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 (C. víridis) is preferred for making the green tea.
