*ARALIAS.
This genus embraces many plants of very diverse aspects, and few that are fitted for the open air in our climate; but in the case of A. canescens, and its relative (A. spinosa), the Angelica-tree of North America, we have subjects which thrive perfectly well in our gardens, and which in the size and beauty of their leaves are far before many “foliage-plants” carefully cultivated in hothouses at a perpetual expense.
*Aralia canescens.—The specimen of this species figured was one of a batch of young plants growing in a London nursery, and sketched in the summer of 1868. The engraving falls far short of rendering the beauty of the plant. It is easy to imagine what a graceful effect may be realised by such an object, either isolated on the turf near the edge of a shrubbery, or grouped with subjects of similar character. Success with these plants may be secured by first selecting a sheltered and warm position, so that their noble leaves may be well developed and not lacerated by storms when they are fully grown; secondly, by giving them a deep, free, and thoroughly-drained soil; and thirdly, by confining them as a rule to a simple and rather dwarf stem, so that the vigour of the individual may not be wasted in several branches. The effect of a plant kept to a single stem, as shown in the plate, is always much superior to that of a branched one. Young plants present this aspect naturally; but old ones may be cut down,
when they will shoot vigorously. If the effect of a full-grown specimen be desired, the shrubbery is the place for it. = A. japonica (Hort.).
*Aralia edulis.—This is a vigorous herbaceous perennial, well suited for those positions in which we desire a luxuriant type of vegetation. It is perfectly hardy, is of a fresh and vigorous habit, and grows 6, 7, and even 8 ft. high in good soil, even so early as the end of June. The leaves attain a length of nearly a yard when the plant is strong, while the shoots droop a little with their weight, and thus it acquires a slightly weeping character. It is rare in this country now, but, being easily propagated, may, it is to be hoped, not long prove so. As it dies down rather early in autumn, it must not be put in important groups, but rather in a position where its disappearance may not be noticed. An isolated position, or one near the margin of an irregular shrubbery, fernery, or rough rockwork by the side of a wood walk, will best suit it. Japan. Division.
*Aralia japonica.—A valuable species, quite distinct from any of the others, with undivided, fleshy, dark-green leaves. It is usually treated as a green-house plant, but is hardy and makes a very ornamental and distinct-looking shrub on soils with a dry porous bottom. It grows remarkably well in the dwelling-house; in fact it is one of the very few plants of like character that will develop their leaves therein in winter. Not difficult to obtain, it may be used with advantage in the flower-garden or pleasure-ground among medium-sized plants—say those not more than a yard high. It would form striking isolated specimens on the turf, and is also very suitable for grouping. A native of Japan. = A. Sieboldi.
*Aralia nudicaulis.—A very vigorous perennial, with a smooth stem scarcely rising out of the ground, bearing large leaves with long-stalked, oval-oblong, pointed, toothed leaflets, and a shorter naked flower-stem, with from two to seven umbels of blossoms. Roots several feet long and highly aromatic. Similar uses to those directed for A. edulis. North America.
Aralia papyrifera (Chinese Rice-paper Plant).—This, though a native of the hot island of Formosa, flourishes vigorously with us in the summer months, and is one of the most valuable plants in its way, being useful for the greenhouse in winter and the flower-garden in summer. It is handsome in leaf and free in growth, though to do well it must, like all the large-leaved things,
be protected from cutting breezes. If this Aralia be planted in a dwarf and young state, it is likely to give more satisfaction than if planted out when old and tall. The leaves spread widely out near the ground, and then it is very ornamental through the summer. Prefer therefore dwarf stocky plants when planting it in early summer. It should have rich, deep soil and plenty of water during the hot summer months. For the public gardens of Paris it is kept underground in caves during the winter; but in private gardens it will doubtless be thought worthy of a place in the greenhouse throughout that season. In Battersea Park a bed of A. papyrifera, 13 ft in diameter, attained a height of 5 ft, from cuttings struck in the spring of 1868. The plants were left out all the next winter, and, although killed to the ground, the thick fleshy roots next season produced numerous strong shoots or suckers. These were produced irregularly, and so numerously that they had to be thinned out in many places; a few spaces only requiring to be filled up. It is easily increased by cuttings of the root, and is usually planted in masses, edged with a dwarfer plant; but as a small group in the centre of a bed of flowers, or even as an isolated specimen in a like position, it is most excellent.
*Aralia racemosa (American Spikenard).—An herbaceous species, with smooth, widely-branching, diverging stems, about 4 ft. in height, and pinnate, slightly downy leaves with ovate heart-shaped leaflets. Flowers numerous, white, in racemose umbels. Thrives best in good soil in shady or half-shady positions. Similar positions, etc., to those for A. nudicaulis and edulis. N. America.
*Aralia spinosa (Angelica tree of North America) is highly useful, in consequence of its beauty of foliage, among subtropical plants. Like many of the hardy things, it should not be placed in positions where it would be necessary to remove it, nor closely associated with tender plants requiring frequent disturbance of the soil Flowers in autumn, small, white, in numerous umbels arranged on a much-branched panicle beset with velvety stellate down. The leaves are twice and thrice pinnate, with ovate, deeply serrated, smooth leaflets. In most cases it grows with a single erect stem—the very type we require—and it should not be allowed to depart from this habit. The stem is fiercely arrayed with spines. On account of its umbrella-like head this fine thing has often been planted in exposed open spaces, where it would produce a distinct feature, but it is better planted where the great leaves will not be lacerated. It generally grows not more than 10 ft. high; and in every size from that down to a plant with a stem not more than 18 ins. high, it may be effectively used in the ornamental garden. It is propagated by cuttings of the roots. N. America.
Aralia macrophylla is a fine large digitate-leaved species which stands summer exposure pretty well, but does not make any growth in the open air; hence it can be but of comparatively slight importance for this purpose. Norfolk Island.
Areca sapida.—A New Zealand palm from 6½ ft. to nearly 10 ft. high, with a beautiful crown of bright-green pinnate leaves, which when young are tinged with a bronze colour: leaflets from 16 ins. to 2 ft. in length, lance-shaped. The young leafstalks are of a greyish red hue. A fine palm for placing in the open air in summer, and equally so for the conservatory in winter and spring. It is of very easy culture, if supplied with plenty of water.
Aristolochia Sipho.—This well-known huge-leaved plant is capable of being used with excellent effect where large and distinct foliage is desired. Generally it is used as a wall plant; but it is far finer when used to cover bowers or any like structure. I have seen a most effective object formed by making the framework of a tent loosely with rough boughs, and then planting the Aristolochia around it. It formed a dense green and singular-looking wigwam. A. tomentosa is smaller, but distinct in tone of green, well worthy of a place, and to be employed in like manner. N. America.
*Artemisia anethifolia.—A hardy perennial species about 4 ft. high, with a simple round stem, woody at the base, and branching vertically above, clothed from about a foot above the ground with much-divided leaves, the segments of which are almost thread-like. Flowers very numerous, small, in a dense, large, terminal panicle, with erect branches. Useful in groups, or as isolated specimens in beds or borders. Division.
*Artemisia annua (Annual Wormwood).—An exceedingly graceful kind of wormwood, with tall stems reaching to a height of 5 ft. or 6 ft. in a season; the foliage is small and fine, and the flowers inconspicuous but arranged in not inelegant panicles. The hue of the plant is a peculiarly fresh and pleasing green, and it forms an elegant object in the centre of a flower-bed or group with plants of like character. Raised from seed as easily as any half-hardy annual.
*Artemisia gracilis.—An exceedingly graceful plant, 3 or 4 ft. high, with leaves cut into very fine hair-like segments, having some resemblance to fennel or other umbelliferous plants with minutely-cut leaves, and of a deep grass-green, except in the hearts of the shoots, where the young leaves are unfolding, where there is a slight hoary pubescence. The flowers are in compound panicles, quite obscure, of a pale green, not at all ornamental in the common sense, but forming a not ungraceful inflorescence. However, the plant is only likely to be grown for its graceful foliage and habit, and the flowers, which only appear in autumn, may be pinched off if not admired. Similar positions to those recommended for the preceding species. Seed.
*Arum crinitum.—The appearance of this plant when in flower is very grotesque from the singular shape of its broad, speckled, contorted spathe. The leaves are divided into five or seven deep segments, the central division being much broader than the others, and the leaf-stalks, overlapping each other, form a sort of spurious stem a foot or 14 ins. high, marbled and spotted with purplish-black. The treatment for this plant is similar to that given for A. Dracunculus; but as it is rather more tender, it will require more care and shelter in winter. Warm borders, fringes of shrubberies, or beds of the smaller subtropical plants, will suit it best. The appearance of the flower is almost too repulsive for the nerves of some persons. Division. S. of Europe.
*Arum Dracunculus.—A strange-looking but handsome plant, with a white stem curiously marbled with black, about 3 ft. high, and very deeply cut palm-like leaves, broadly veined and spotted with white. The spathe is of a pale green colour on the outside and of a deep purple-violet within, and, as well as the flowers, exhales a powerful carrion odour. Requires a light, deep, and dry soil, and does best in half-shady positions. Easily multiplied by division in spring or autumn. It is best fitted for the fringes of shrubberies, etc., or among the vegetation that sometimes starts from the bottoms of warm walls. S. of Europe.
*Arum italicum.—This plant, which is a native of the Isle of Wight and the Channel Islands, resembles the common A. maculatum in habit and in the shape of its leaves, which are, however, of a dark bluish-green colour, handsomely spotted with white, and marked with yellow veinings. Although it is a very hardy plant, and will thrive almost anywhere in moist soil and a shady position, it will be better to place it in sheltered positions along the sunny fronts of shrubberies, amidst low-spreading evergreens, and in cosy spots about the flanks of rock work and ferneries, to prevent its handsome foliage from being disfigured by cold wintry winds. One great merit of this is that it may be used to ornament positions in which few other plants will thrive,—as, for instance, under trees, groups of shrubs, etc. Easily multiplied by division in the end of summer and in autumn. S. of Europe.
*Arundo conspicua.—A companion for the Pampas grass, though by no means equal to it, as has been stated by some writers. In some very fine deep and free sandy loams it attains a height of nearly 12 ft., but this is rare. As a conservatory subject it is fine in flower, and it will be often seen in large conservatories after a few years. A large pot or tub will be necessary if it is grown indoors. The drooping foliage will always prove graceful, and it sends up long silvery plumes, drooping also, and strikingly beautiful. Judging by its different appearance when freely grown in a tub indoors, and when planted out even in favourable spots, my impression is that it by no means takes so kindly to our northern climate as the Pampas grass. However, it is well worth growing, even in districts where it does not attain a great development. It comes into flower before the Pampas grass, and may be considered as a sort of forerunner of that magnificent herb. New Zealand.
*Arundo Donax.—This great reed of the south of Europe is a very noble plant on good soils. In the south of England it forms canes 10 ft. high, and has a very distinct and striking aspect. It will grow higher than that if put in a rich deep soil in a favoured locality; and those who so plant clumps of it on the turf in their pleasure-grounds will not be disappointed at the result. Nothing can be finer than the aspect of this plant when allowed to spread out into a mass on the turf of the flower-garden or pleasure-ground. It seems much to prefer deep sandy soils to heavy ones; indeed, I have known it refuse to grow on heavy clay soil, and flourish most luxuriantly on a deep sandy loam in the same district. Like all large-leaved plants, it loves shelter. No garden or pleasure-ground in the southern parts of England and Ireland should be without a tuft of it in a sheltered spot. But, fine as it is for effect and distinctness, its variegated variety is of more value for the flower-garden proper.
*Arundo Donax versicolor.—We have already noticed several fine things for grouping together, or for standing alone on the turf and near the margin of a shrubbery-border, and this is as well suited for close association with the choicest bedding-flowers as an Adiantum frond is with a bouquet. It will be found hardy in the southern counties, and, considerably north of London, may be saved by a little mound of cocoa-fibre, sifted coal-ashes, or any like material that may be at hand. In consequence of its effective variegation, it never assumes a large development, like the green or normal form of the species, but keeps dwarf, and yet thoroughly graceful. It is of course best suited for warm, free, and good soils, and abhors clay, though it is quite possible to grow it even on that with a little attention to the preparation of the ground. But it is in all cases better to avoid things that will not grow freely and gracefully on whatever soil we may have to deal with: and it is to those having gardens on good sandy soils, and in the warmer parts of England, that I would specially recommend this grand variegated subject. For a centre to a circular bed nothing can surpass it in the summer and autumn flower-garden, while numerous other charming uses may be made of it. Not the least happy of these would be to plant a tuft of it on the green turf, in a warm spot, near a group of choice shrubs, to help, with many other things named, to fill up the gap that is now nearly everywhere observed between ordinary fleeting flowers and the taller tree and shrub vegetation. It is better to leave the plant in the ground, in a permanent position, than to take it up annually. Protect the roots in the winter, whether it be planted in the middle of a flower-bed or by itself in a little circle on the grass. Increased by placing a shoot or stem in a tank of water, when little plants with roots will soon start from every joint; they should be cut off, potted, and placed in frames, where they will soon become strong enough for planting out.
*Arundo Phragmites (Common Reed).—A native marsh-or water-plant, 5 ft. or 6 ft. high, bearing when in flower a large, handsome, spreading, purplish panicle. The stems are smooth, simple, very erect, and grow closely together. The plant is only attractive when in flower, as its flat, ribbon-like leaves do not of themselves present any very striking appearance. Useful for the margins of artificial waters, etc., to which it may be brought from its wild haunts. It should, however, if possible, be kept in one spot and not allowed to spread too much.
*Asclepias Cornuti.—A handsome hardy perennial from N. America, sending up from its running, underground rootstock a number of erect, unbranched stems, from 4 ft. to 6½ ft. high, thickly covered with large opposite oval leaves. The flowers are of a light rose-colour, and agreeably fragrant, and are borne in large umbels at the tops of the stems. The plant does well in almost any kind of soil or position, and is well adapted for planting in places which do not require much attention. As it spreads very rapidly at the root, it is better to exclude it from small beds or gardens, which would soon be overrun by it. Several other species are in cultivation, the best of which are A. speciosa (Douglasii), A. incarnata, and A. tuberosa.
*Asparagus Broussoneti (Giant Asparagus).—A vigorous, climbing asparagus, with a tapering, shrubby stem, 10 or 12 ft. high. The flowers are small and inconspicuous, and are followed by numerous small red berries. An excellent subject for tall trellises, rustic bowers, stumps of trees, tall poles, etc. Canary Islands.
Asplenium Nidus-avis.—This is a remarkable fern, which has been placed out of doors in the garden in summer, from early in June to October; but it is not vigorous or hardy enough to be generally recommended for this purpose. However, as it may have been noticed in abundance at Battersea Park, I allude to it here. The leaves are rather broad, pointed, and undulating, nearly 3 ft. long, and form roundish, spreading, nest-like tufts. It is a favourite subject in places where large collections of tropical ferns are grown, and in such places a plant may be tried in the open air in a very warm, shady, and perfectly sheltered position. E. Indies.
*Astilbe rivularis.—A large-leaved and striking plant from Nepaul, with the habit and general appearance of a Spiræa, growing to a height of more than 3 ft., and of a free and graceful habit, which makes it useful for association with the finer-foliaged herbaceous plants, and for dotting here and there in the wild or picturesque garden. It keeps its foliage well through the season, unlike some herbaceous plants, and is therefore all the more valuable. Flowers late in summer, small, yellowish-white, in large panicled spikes. The radical leaves are broad, twice ternate with toothed divisions, and the base of the leaf-stalk is covered with numerous rough tawny hairs. Being pretty hardy, the Astilbe usually succeeds well in any cool rich soil, and best in half-shaded positions. Easily multiplied by division. It is suited for isolation, borders, fringes of shrubberies, or for groups of hardy plants.
*Astilbe rubra.—A very pretty and hardy plant, also resembling a. Spiræa in habit and appearance, and growing from 4 ft. to 6 ft. high. The leaves are twice ternate, with oblique, heart-shaped leaflets, 1 in. to 2 ins. long, and with lengthened serrated points. The flowers are numerous, in dense panicles, and of a rose-colour, appearing late in summer and in autumn. The same positions, etc., as those for the preceding kind. North America, Japan, and mountains of Northern India.
*Bambusa.—I wish to call the attention of all horticulturists who live in the southern and more favoured parts of these islands to the fact that there are several bamboos and bamboo-like plants from rather cool countries that are well worth planting. Nothing can exceed the grace of a bamboo of any kind if freely grown; but if starved in a crowded house, or grown in a cold dry place, where the graceful shoots cannot arch forth in all their native beauty, nothing can be more miserable in aspect. In cold bad soils and exposed dry places in the British Isles these bamboos have little chance; but, on the other hand, they will be found to make most graceful objects in many a sheltered nook in the south and southwestern parts of England and Ireland. We have some knowledge of the capabilities of one kind in this country. In a well-sheltered moist spot at Bicton I have seen Bambusa falcata send up young shoots, long and graceful, like the slenderest of fishing-rods, while the older ones were branched into a beautiful mass of light foliage of a distinct type. The same plant grows in the county of Cork to a height of nearly 20 ft. This is the best known kind we have. At Paris I was fortunate enough to observe various other kinds doing very well indeed, although the climate is not so suitable as that of Cork or Devon. These were Bambusa edulis, aurea, nigra, Simonii, mitis, Metake, and viridi-glaucescens, the first and last of this group being very free and good. All the others will prove hardy in the south of England and Ireland, though, as some of them have not yet been tried there, it requires the test of actual experiment. Those who wish to begin cautiously had better take B. Simonii, viridi-glaucescens, and edulis to commence with, as they are the most certainly hardy, so far as I have observed. The best way to treat any of these plants, obtained in summer or autumn, would be to grow them in a cool frame or pit till the end of April, then harden them off for a fortnight or so, and plant out in a nice warm spot, sheltered also, with good free soil—taking care that the roots are carefully spread out, and giving a good free watering to settle the soil. There are no plants more worthy of attention than these where the climate is at all favourable, and there are numerous moist nooks near the sea-side where they will be found to grow most satisfactorily, as well as in the south.
*Bambusa aurea.—A very hardy and graceful Chinese species, differing but slightly from B. viridi-glaucescens in size and habit, and forming elegant tufts with its slender much-branched stems, which attain a height of from 6½ ft. to 10 ft., and are of a light-green colour when
young, changing into a yellowish hue, and finally becoming of a straw-yellow when fully grown. The leaves are lance-shaped acute, light green, and are distinguished from those of B. viridi-glaucescens by having their under surface less glaucescent, and the sheath always devoid of the long silky hairs. The preliminary remarks on culture, etc., will apply to all the species here described.
*Bambusa edulis.—A hardy and vigorous kind, with very elegant light-green shoots and olive-green stems, attaining a height of 10 ft. in the neighbourhood of Paris. The leaves are small, and the plant is not nearly so branching as in some other kinds.
*Bambusa falcata (Arundinaria falcata).—A very ornamental species from Nepaul and the Himalayas, and at present the only kind of bamboo much planted with us. It grows from 7 ft. to 20 ft. high, and has woody, twisted, smooth stems of a yellowish-green or straw-colour, knotty, bearing on one side of each of the knots a bundle of small branches equally knotty and twisted. The whole plant has a pale yellowish hue, except in the young spikelets and sheaths, which are occasionally purplish. The leaves are of a fine delicate green, from 4 ins. to 6 ins. long, ribbon-like, linear-acute, sickle-shaped, in two rows, short-stalked, and sheathing. It is hardy over the greater part of England and Ireland, but only attains full development in the south and west. I have seen it attain great luxuriance in Devon, and nearly 20 ft. high near Cork, though in many districts it is stunted. It loves a deep, sandy, and rich soil, and plenty of moisture when growing fast.
*Bambusa Fortunei.—A pretty dwarf variegated species from Japan, of which I have not seen the green form in cultivation, with very dwarf, slender, branching, hollow, half-shrubby stems, seldom growing more than 18 ins. high, and with very short internodes. The leaves are 3½ ins. to 8 ins. long, linear-lance-shaped, abruptly pointed, somewhat rounded at the base, serrated and often fringed with long hairs on the margin, downy on both sides; they are distinctly variegated, the transverse veins being often of a bottle-green colour; stalks very short and hairy. This kind has proved hardy in our gardens, but it has not the charm of grace possessed by the other kinds, and is chiefly desirable in collections of variegated and edging plants.
*Bambusa japonica (B. Metake).—A large-leaved and rather dwarf species from Japan, growing from 4 ft. to 7 ft. high, with erect thickly-tufted stems, which are entirely covered by the sheaths of the leaves; the branches are also erect. The leaves are lance-shaped, with a very sharp point, dark green, persistent, narrowed into a short leaf-stalk, and nearly a foot long. This species sometimes flowers with extraordinary profusion at the expense of a portion of the foliage, which withers away and leaves the naked stems exposed. This may, however, be prevented to some extent, by placing the plants on mounds somewhat above the level of the surrounding soil. I have seen it thrive very freely in the late Mr. Borrer’s garden in Sussex, and in one or two other places. It loves a peat soil, or a very free moist and deep loam, and runs a good deal at the root.
Bambusa mitis.—A fine and vigorous kind from Cochin China, somewhat tenderer than most of the other
kinds enumerated, though no doubt it will be found to thrive in the milder southern districts; or it may be found useful if grown in the conservatory in winter and placed out in the open air in summer, as is sometimes done with B. arundinacea, which otherwise could not possibly be seen out of doors in our climate. Panicle simple, erect, close; spikes long, imbricated. Leaves rather large, lance-shaped, striated, clasping the stem, which is woody and tapering; nodes rather distant, and not very prominent.
*Bambusa nigra.—A rather compact-growing Chinese kind, with nearly solid stems, and thinner leaves than those of any other species. The stems are smooth and bushy, about 7 ft. high, of a light green, dotted and striped with purple when young, changing to a glistening black when fully grown; they branch very much at the top, and sometimes from the base up. The leaves are oval-oblong, acute, shortly-stalked, with a hard, dry, persistent sheath; their tender green colour contrasting finely with the blackish hue of the stems. It is best planted as isolated specimens near the margins of shrubberies, or on slopes in the pleasure-ground in warm, sunny, and sheltered positions, in deep, sandy, and well-drained soil.
*Bambusa Quilioi.—A Japanese species of vigorous growth, with robust green stems and bright-green leaves, polished above and slightly mealy beneath, the ligule bearing a little bundle of brownish-grey hairs at the top. This kind I first saw in the gardens of the Acclimatisation Society at Paris, where it was thriving vigorously, and I have little doubt of its proving valuable in Britain.
*Bambusa Simonii.—A handsome, distinct, and vigorous species, which has grown very freely for some years past in the neighbourhood of Paris. The stems are numerous and grow as much as 10 ft. high in a season. They are mealy-glaucous at the joints, and the branchlets are numerous and rather closely crowded. The leaves are narrow, sometimes nearly a foot long, and are occasionally striped with white. This species, which was obtained from China some years since, has thriven very well in the gardens at Paris, where M. Carrière first drew my attention to it. From what I have seen it do there I have no doubt it will prove of great value in the milder southern parts of England and Ireland.
*Bambusa violascens.—A hardy and vigorous kind, intermediate between B. nigra and B. viridi-glaucescens, most resembling the last-mentioned however. It has blackish-violet much-branched stems, which assume a yellow tinge with age. The leaves are green above, bluish-grey beneath, with an elongated ligule surrounded by a bundle of black hairs. Native of China.
*Bambusa viridi-glaucescens.—A species from Northern China, which has been proved very hardy and free in the Paris gardens, and will, probably, in warm parts of our islands, make a more vigorous growth and prove a more beautiful object than any other kind. The stems, of a light-yellowish-green, grow from 7 ft. to 12 ft. high, branching from the base, each branch again branching very much. The leaves are very numerous, especially at the ends of the branches, of a pale-green, bluish underneath, sheathing the stem for a considerable length. It forms a fine object when planted as isolated specimens in sheltered warm glades in the pleasure-ground, or in snug open spots near wood-walks, in very deep, rich, light, and well-drained soil.
*Bambusa viridis striata.—Described as a vigorous-growing, hardy kind, with numerous branches, having its long leaves green on both sides, and marked with bands, some of a yellowish and others of a deeper green. It is a native of Japan, and was recommended by MM. Thibaut and Ketteleer of Paris, but I have had no experience of its growth.
*Baptisia australis.—A handsome hardy perennial from N. America, forming strong bushy tufts from 3 ft. to 5 ft. high, and from 3 ft. to 6 ft. across, with sea-green trifoliate leaves which reflect a metallic lustre. The flowers are of a delicate blue, with wings of a greenish-white colour, and are borne in long erect spikes. Grows well in ordinary, deep, well-drained soil, preferring a sandy loam. B. exaltata and B. alba are closely allied to the preceding species, and form equally handsome bushes. The foliage of these is of a character to permit of their being grouped along with some of the finer perennial foliage-plants with good effect. Division.
*Berberis Aquifolium.—A well-known shrub from N. America, with simple stems from 3¼ ft. to 6½ ft. high, and very glistening, bright green leaves, each consisting of 7 or 9 sessile, oval, spiny leaflets. Where the plant is fully exposed to the sun, the foliage frequently acquires an agreeable reddish tinge. There are numerous varieties, of which B. floribunda may be mentioned as very handsome in habit and profuse in flower, and B. nitens, remarkable for the extremely glossy appearance of the old leaves, which when young are of a rich bronze changing to a dark green. This variety is of a dwarf and compact habit. It requires a shady situation and a compost of peat, loam, and sand. Though so very common, it will be found worth planting in some places among groups of hardy things, and also for isolation on the turf, its leaves being very ornamental.
*Berberis Bealii.—This is perhaps the finest of all the hardy species, whether as regards foliage or flower, while the fruit, in colour and size, surpasses that of any other kind. The leaflets vary to a very great degree on the same plant, both in form and size, some being 5 ins. long and 3½ ins. broad, the average size being 3 ins. long by 2 ins. broad: some again are nearly square, while others are long and narrow, with a very stiff triangular point. Shade, shelter from gusts of wind, and rich, well-manured soil are absolutely necessary to do full justice to the merits of this species. By pruning it to a single stem, it may be made to assume a very effective palm-like character. It is easily propagated from seed; a single berry frequently producing three plants. Being a noble subject for quiet half-shady wood-walks in peat or moist sandy loam, it should be much planted in the southern and milder districts. Where it thrives freely, it would prove a fine object on the margins of shrubberies grouped with the hardy “subtropical” plants, or indeed in any position.
*Berberis japonica.—A very handsome species, 5 ft. or 6 ft. high, with very leathery, pinnate, spiny leaves, from 1 ft. to 18 ins. long, slightly tinged with pink when first opened, then becoming pale green, and finally changing to dark green blotched with yellow. Flowers yellow, in large racemes, succeeded by large handsome
clusters of purple berries. This is also a fine kind for half-shady walks, and for similar positions and soil to those recommended for B. Bealii. Japan.
*Berberis nepalensis.—The noble habit of this plant makes it peculiarly valuable, possessing, as it does, the grace of a luxuriant fern with the rigidity of texture and port of a Cycas. The leaves are occasionally 2 ft. in length and of a pale green colour, sometimes with eight pairs of leaflets and an odd one: some of the leaflets 6 ins. long and nearly 2 ins. broad, with coarse spiny teeth on the margin. The inflorescence is very striking and beautiful. The Nepaul Barberry is one of those subjects that are too hardy to perish in our climate, yet which do not usually attain perfect development in it. It exists about London in the open air, and flowers in early spring; but the leaves seldom attain one-fourth of their full development, and the plant scarcely ever displays its vigorous grace. In mild parts, principally in the south and south-west, it grows more freely, and when judiciously placed in sheltered positions, in deep and rather sandy soil, it becomes a beautiful object. Where it thrives in the open air, it may be most tastefully used in the more open spots near the hardy fernery, here and there among “American plants,” or other choice shrubs with simple leaves, and also isolated in the grass a little way from the margin of the shrubbery in sheltered spots in the pleasure-ground. It should also, in places favourable to its growth in the open air, prove very useful as a hardy “subtropical” plant. Where it does not thrive well in the open air, it should not be planted. Nepaul.
*Beta cicla variegata (Chilian Beet).—Under this name a very showy plant has recently come into cultivation. When well grown the leaves are often more than a yard long, and present a vivid and most striking coloration. Their midribs are 4 ins. or more across, and vary from a dark deep waxy orange to vivid polished crimson. The splendid hue of the lower part of the leaf-stalk flows on towards the point, and spreads in smaller streams through the main veins and ramifications of the great soft blade of the leaf, which is often 1 ft. and even 15 ins. in diameter, if the plant be in rich ground. The under sides of the leaves are most richly coloured, and the habit such that these sides are well seen. It requires the treatment of an annual—to be raised in a gently heated frame, and afterwards planted out in very rich ground, though it may also be kept over the winter in pots. It varies a good deal from seed, and the most striking individuals should be selected before the plants are put out. Used sparingly, its effect would perhaps be more telling than if in quantity, and it is well suited for isolation. Chili.
*Bocconia cordata.—This is a fine plant in free soil, but comparatively poor in that which is bad or very stiff. It forms handsome erect tufts from 5 ft. to over 8 ft. high, and is admirably suited for embellishing the irregular or sloping parts of pleasure-grounds. The stems grow rather closely together, and are thickly set with large, reflexed, deeply-veined, oval-cordate leaves, the margins of which are somewhat lobed or sinuated. The flowers, which are rosy-white and very numerous, are borne in very large terminal panicles. The flowers are not in themselves pretty, but the inflorescence, when the plant is well grown,
has a distinct and pleasing appearance. The plant is seen to best effect when isolated, and does well in ordinary garden-soil or free sandy loam. It attains its greatest size when placed in the angle of two walls which shelter it from the north and east, which seems to indicate that it does not like sudden changes of temperature and light. It should not be stirred too often, nor divided for several years. It will prove a good thing for associating with other fine hardy plants in bold groups. Seed or cuttings. China.
Bocconia frutescens.—A vigorous-growing Mexican shrub, 3½ ft. to nearly 6 ft. high, with few and very brittle branches, large, sea-green, handsome leaves, and greenish flowers. Very effective when placed on grass-plats, either in groups, or as isolated specimens. It requires a somewhat warmer climate than ours to thrive well, though it is sometimes seen in fair condition in the London parks. A mixture of free sandy loam and peat, well-drained ground, and an airy position are necessary. Multiplied by sowing in a hotbed in spring, and may be placed out from June to the end of September. It is difficult to propagate it by cuttings.
*Brassica oleracea crispa.—A handsome kind of cabbage nearly 4 ft. high, with elegantly-cut arching leaves, the divisions of which are finely curled or frizzled. In autumn and winter it may be advantageously employed in the embellishment of winter-gardens, the leaves being at their best during that part of the year.
A still more striking subject is B. o. palmifolia, which attains a height of 6½ ft., and bears its leaves near the summit of the stem, having quite a palm-like appearance in the end of the summer and in autumn. This kind might be used with good effect in various positions, as its “cabbage” character is not so evident. The fact of their being cabbages prevents many people from using these really ornamental plants.
The variegated Kales have been much employed and with a very good result in the winter-garden at Wardie Lodge in Scotland and in other places: they lose their beauty early in spring. “To keep them dwarf and compact, and to bring out their fine colours,” say Messrs. Stuart and Mein, “we sow at the beginning of March thinly. After the plants are a moderate size, we transplant them into a poorish soil, in an open space of ground, but not too closely together. They remain there until they are wanted for use, when they are removed at any time to the winter-garden. We plant out into our beds in November, and keep the heads with their foliage close to the ground. We cut off all the lower rough leaves, leaving the rich-coloured head or centre, which in all weathers will be found to stand up neat and trim, even in bright frosty weather. As the plants are thus much reduced in size, they can be planted much closer in the beds. We may add that, as in other hybrids, worthless plants will occasionally make their appearance: these we discard. No plants should be selected for the beds except those showing pleasing shades of colour.”
Brexia madagascariensis.—A handsome shrub with a slender erect stem (which sometimes attains a height of 25 ft. or 30 ft. in its native country, but with us is seldom seen more than a fourth of that), clothed with alternate, leathery, long, rather narrow, light-green leaves, nearly or quite smooth at the margin. It is one of the tropical stove-plants that have stood well in the open air from June to early in October, but very few places can spare it for this purpose. It requires ordinary stove culture during winter and spring, and should only be placed out after having made a strong growth, and having that growth hardened off. Madagascar.
*Buphthalmum speciosum.—A hardy, distinct, and vigorous herbaceous plant, the stems of which are stout, very slightly branching, and about 4 ft. high, with broad, oval-acute leaves mostly clustered around the base of the plant, the lower ones falling gracefully towards the earth. The flowers, which have a red or purple disk and yellow rays, are more than 2 ins. across, and are terminal, solitary, long-stalked, borne in the axils of the upper leaves, and appear in June, July, or August, according to the season. The plant seldom flowers well before the third year. It is of easy culture in any soil, is increased by division in autumn, winter, or spring, and is best fitted for association with the more vigorous herbaceous plants in rough places. S. of Europe.
Caladium esculentum.—This species has, for outdoor work, proved the best of a large genus with very fine foliage. It is only in the midland and southern counties of Great Britain that it can be advantageously grown, so far as I have observed; but its grand outlines and aspect when well developed make it worthy of all attention, and of a prominent position wherever the climate is warm enough for its growth. It may be used with great effect in association with many fine foliage-plants; but Ferdinanda, Ricinus, and Wigandia usually grow too strong for it, and, if planted too close, injure it. This may have been noticed particularly in cases where it was used as a bordering to masses of the strong-growing kinds above named. For all kinds of stonework, vases, etc., it is peculiarly effective and beautiful. This plant, requires, above all others, a thoroughly-drained, light, rich, warm soil. In times of great heat, it should be plentifully watered, and occasionally with liquid manure. The month of May is the best time for planting it out; and if groups are formed, the plants should have an interval of 2 ft. or 2½ ft. between them. The foliage generally arrives at its full beauty and development in August and September. At the approach of cold frosty weather, all the leaves, or all but the central one, should be cut down to within an inch or two from the crown, and a few days afterwards the tubers should be taken up and left on the ground for a few hours to dry:
they should then be stored on the shelves of a greenhouse, or in a cellar or other place where they will be sheltered from frost and moisture. By placing the tubers in a hotbed in March, plants may be obtained with well-grown leaves for planting out in the open air about the end of May or the beginning of June. New Zealand.
Caladium odorum (Colocasia odora).—A very striking plant, with stout stems usually from 3 ft. to 8 ft. in height, but growing much taller in a warm stove. The leaves are erect, very broad, and heart-shaped, marked with strong veinings, and frequently measure more than 3¼ ft. in length. The flowers are exceedingly fragrant. It is a fine subject for isolation on grass-plats, its tall arborescent habit distinguishing it from all the other species; but it is unfortunately too tender to thrive in our climate except in sunny sheltered dells in the southern parts, and should not be planted out until June. E. Indies.
*Calla æthiopica (Lily of the Nile).—This well-known plant may be grown either as an aquatic in pieces of ornamental water, fountain-basins, etc., or in the open ground in cool, moist soil, and equally well in positions exposed to the full sun and in those which are shaded. Being so very distinct in leaf and beautiful in bloom, this old favourite will be seen to as much advantage grouped with the smaller fine-leaved plants in beds as ever it has been in our stoves or windows. S. Africa.
