Hypericum Calycinum
Large-calyxed St. John's Wort, or Rose of Sharon; Nat. Ord. Hypericaceæ
A very ornamental deciduous shrub, but often green throughout the winter. This I claim the privilege of introducing amongst herbaceous perennials; it is a well-known and favourite "old-fashioned" flower, in fact, a native of Ireland. The old name for it was "Cup St. John's Wort." In July it is in splendid form, and, familiar as we are with it, it never fails to win admiration. How charming are its large, shining, golden blossoms, nestling amongst the bright but glaucous foliage! the bundled tassels composed of numerous filamentary stamens glistening like threads of gold; and though often seen one can never tire of it. As a flower, it is distinct in form, showy, and richly effective.
It grows to the height of 1ft. or 18in.; the flowers are 4in. across, of a rich golden-yellow colour, and produced singly on the very leafy stems which, at the base or at their more woody parts, are square, the upper parts being nearly round. Short flower-stalks issue from the side and near the top, a small new growth being produced in juxtaposition with the blossom, the said growth being composed of half-a-dozen or so smaller-sized leaves of a pale apple-green, charmingly suffused with a glaucous hue. The calyx of five sepals is very large, whence the specific name, and each sepal is nearly round and cupped, whence the old common name, "Cup St. John's Wort"; the five petals are 2in. long and widely apart; stamens very numerous, long, thready, and arranged in tufts. These are very beautiful, and form the most conspicuous part of the flower; like the other seed organs, and also the petals, they are of a rich, glistening, yellow colour. The leaves are closely arranged in pairs, opposite, and nearly sessile; they are 2in. to 3in. long, and about 1in. broad, oval-oblong, blunt, smooth, and leathery. When young, they are as above described, but when older, they are of a dark, shining green colour, and somewhat reflexed. The under sides are finely reticulated or veined, and sometimes the foliage is spotted with brown. The habit of the shrub is neat, the short stems being numerous and semi-prostrate, forming dense, even masses of verdant foliage.
Such a subject as this cannot be too highly esteemed on the score of the merits already set forth; but there are other good qualities which I will briefly refer to presently. There can be little doubt that the fine parts and many uses, decorative and otherwise, of most of the "old-fashioned" flowers have much to do with the high and continued esteem in which they are held. Not one of the least recommendations of this St. John's Wort is that it can be grown with great success under the shade of trees. It is one of the very few subjects that will bloom freely in such situations. It is, therefore, very valuable; besides, as regards its period of flowering, it comes in nicely after the vincas are over. These two genera are, perhaps, the best hardy flowering shrubs we possess for planting in the shade of trees. I scarcely need add that for more open situations, as rockwork and borders, it is in every way suitable.
To the lover of cut flowers this must prove one of the most satisfactory, not only because of its beauty, but also because they are produced for fully three months—into September—and they are sweetly scented, like wallflowers. A flower-topped stem forms a perfect and unique decoration for a lady's hair; sprays in small vases are exquisite, whilst a bowlful for the table (without any other flower) is very fine indeed—let the reader try these simple styles of decoration. Also, mixed with other flowers, it is one of the most telling; none of the yellow exotics can excel it. It is now before me, with a few sprays of the pink sweet pea and a bold spike of the white variety of goat's-rue; the blend is both delicate and effective. As a cut flower it can hardly be misused, provided it is not crowded.
Its culture is simple. Any sort of garden soil suits it, but it prefers a sandy loam. A winter top dressing of stable litter will help to produce greater luxuriance and a longer succession of flowers. It quickly and broadly propagates itself by means of its creeping roots; these may be at any time chopped off, with a sharp spade, in strong pieces, which, if planted in deeply-dug loam, will make blooming specimens for the following season.
Flowering period, July to September.
Iberis Correæfolia
Nat. Ord. Cruciferæ
This is a hybrid and much improved variety of the well-known evergreen and shrubby Candytuft, often called "Everlasting Candytuft." A more pronounced remove from its parents could hardly be found in any plant or shrub than is this. There are evident improvements in colour, size, and habit, both in foliage and flowers. It is also a robust grower and perfectly hardy, in these respects being very different from I. Gibraltarica. None of the shrubby Candytufts can compare with this for usefulness and beauty; it comes into flower in May, and is in its greatest beauty in early June. It remains in fine form for fully four weeks. At first the flowers seem small, but later they form broad masses of dazzling whiteness, the corymbs being the size of a crown piece. Not only is this wholly distinct from its relatives, but it is one of the most useful flowers and evergreen shrubs which can be introduced to a garden. It cannot be planted wrong as regards either soil or situation. It forms a rich surfacing subject, all the year round, to other tall plants, as lilies, &c. It looks well as a front specimen in the shrubbery, makes an effective and neat appearance at the angles of walks, or as an edging it may be cut and trimmed as a substitute for a grass verge; it thrives on sunny or almost sunless outhouse tops, and on rockwork it is superb; moreover, it grows fairly well in reeky towns, and though its white flowers may be soiled the day they open, its bright green leaves and dense habit render it a pleasing object.
The flowers are arranged in flat heads at first, but as the stems become elongated and the succession of buds open, a long round cluster is formed by the old flowers remaining (as they do for weeks), such heads or spikes sometimes being 3in. long. There is much substance in the petals, which causes them to glisten in strong light; the flower stems are produced 5in. or 6in. above the foliage, their total height rarely exceeding a foot. The leaves are numerous, of a dark shining green colour; in length 1½in., and over ¼in. broad near the ends; their shape is spathulate, obtuse, entire, and smooth; the new set of foliage contrasts pleasingly with the old, and its growth is completed during the flowering period; the woody and slender branches are numerous and procumbent.
Besides the positions already mentioned, in which this shrub may usefully be planted, there is none more so, perhaps, than that of rough or unsightly corners, where, if it is provided with a little loam, it will soon adapt its form to the surroundings. The flowers in a cut state are not only sweet-smelling, but very useful where white bloom is needed in quantity, as for church decorations. I. correæfolia can scarcely be said to need cultural treatment, but it is useful to bear in mind that it may be much more finely bloomed if generously treated, which simply consists in nothing more than giving it a sunny place and sandy loam, well enriched with old manure. Specimens so treated, which were cuttings only two years ago, are now 2ft. in diameter, and covered densely with large flowers; and how lovely some of the pretty weeds which have sprung up amongst the bushes, and mingle their flowers among the masses of white, appear—such as Spring Beauty (Claytonia), pink flowers; the Maiden Pink (Dianthus deltoides), rose; Self-heal (Prunella pyrenaica), purple; and the forget-me-nots! This comparatively new Candytuft is as easily increased as grown, by either layers or cuttings; the latter may be put in almost any time, early spring being the best; if put in in June, no better quarters can be given than under the shade of shrubs, where the soil is sandy loam.
Flowering period, middle of May to middle of June.
Iris Fœtidissima
Gladdon, Gladwin, or Spurge-wort; Nat. Ord. Iridaceæ
A British species, occurring largely in some parts, in shady woods and swampy places near the sea. It is evergreen and of a pleasing form throughout the year. Its flowers are of a dull colour, and not likely to be much esteemed, more especially when in midsummer there are so many beautiful kinds around; still, it merits a place in our gardens. Its handsome berry-like seeds, which are so attractively conspicuous in December, are much more desirable than its flowers, ready as they are for our use at Christmas time.
It grows 2 ft. high, and is a water-loving plant, but may be easily grown in the more moist parts of the garden. The large pod is three-cornered; the husks having turned brown, become divided, and expose to view the large, orange-coloured seeds, which, later, turn to a reddish-brown. They are held in the husks for many weeks and strong winds do not displace them; they are very effective amongst the dark green foliage, and may be cut if desired, as they often are, for indoor decoration. They may be used in a hundred different ways, but never do they show to more advantage than when cut with long stems and placed in a vase with some of their own dark green sword-shaped leaves; these last-named, by the way, may be appropriated throughout the winter as a dressing for other flowers. There need be no difficulty in growing this species, for if the soil is not naturally moist in summer, a thick dressing of rotten stable manure will meet the case. As a matter of fact, my specimen is grown in a bed fully exposed to the sun; the soil is well drained, and stone-crops are grown in the next bed to it; no water is ever given to established plants, and still the Gladwin is well fruited; the soil is deeply tilled, and there is a thick covering of manure. It is easily propagated by division of the roots in autumn or early spring.
Flowering period, June to August.
Isopyrum Gracilis
Slender Isopyrum; Nat. Ord. Ranunculaceæ
This is a hardy herbaceous plant, of great beauty. The flowers are not showy, but their great numbers and arrangement render them of importance in what may be termed a fine-foliaged subject. The Isopyrums are very nearly related to the thalictrums or rues, and this one greatly resembles the maidenhair-like section, one of which it is often taken for. There is, however, an important botanical difference between the two genera: the thalictrums have no calyx, and the Isopyrums have. Still, as the flowers of both are very small, that feature is not very observable. As a decorative plant it may be classed with the maidenhair-like rues, and the illustration may be said to give a fair idea of three or four species.
Fig. 54. Isopyrum Gracilis.
(One-eighth natural size; 1, leaflet, full size.)
The Isopyrum under notice grows 12in. or 15in. high, and produces its dark brown flowers on slender, well-branched stems, forming feathery panicles, which have a graceful appearance. The flowers are very small, and composed of a five-cleft calyx, five equal petals, and numerous long, pendent seed-organs; the stems are elegantly furnished with the fine-cut foliage. The leaves are large, but the leaflets small, as may be seen by the one given, full size, in the drawing (Fig. 54), being somewhat cordate, lobed, and dentate; they have hair-like stalks, which add to their elegance of arrangement, and their glaucous colour further enhances their effectiveness.
This light and diffuse subject may be usefully planted to relieve other kinds; in beds or lines it looks well, having a lace-like effect; as a cut flower or spray it nearly equals maidenhair, and for mixing with large flowers, it perhaps excels. Either cut or in the growing state it is very durable. It may be grown in average garden soil, but to have it fine, it should be given vegetable soil and a moist situation, not shaded. It is propagated by seeds or division of the roots in autumn.
Flowering period, July and August.
Jasminum Nudiflorum
Nude-flowered Jasmine; Nat. Ord. Jasminaceæ
Fig. 55, Jasminum Nudiflorum.
(One-third natural size.)
This was brought to this country from China a little less than forty years ago, and, as proof of its sterling worth, it is already in extensive use. The whole genus is a favourite one; but there is a special and most attractive feature about this species that is sure to render it desirable to all—it flowers freely in midwinter, and it does so in the open garden. Like many of the genus, this species comes from a very warm climate, and for a time it was grown in glasshouses as a tender shrub, where it flowered during the winter months. It is now found to be a perfectly hardy subject, not only withstanding our most trying seasons without the least injury, but also proving true to the month of December as the period when it begins to produce its numerous golden flowers. It is a climbing deciduous shrub, though it has neither the habit of clinging nor twining.
The shrub produces bloom when only 18in. high, but it often grows to as many feet, and even taller. The flowers are borne singly at the joints from which the leaves have fallen, and as the latter were opposite, the blossom appears in pairs on the new twigs. In the bud state they are drooping, and are marked with a bright chestnut tint on the sunny side. The calyx is ample, almost leafy, but these parts are hidden when the flower opens and becomes erect. The form of the Jasmine blossom is well known; in size this one is rather larger than a full-blown violet, and quite as sweetly scented, which is saying very much, but the colour is yellow; the petals are of good substance and shining; the flowers last a long time, even during the roughest weather, they open most during sunshine, but do not wait for it, and they remain open until they fade. The leaves, which are produced in early spring, are very small and ternate; leaflets of unequal size, ovate, downy, and of dark green colour. The wood is very pithy, square, with sharp corners, and having the appearance almost as if winged; the younger branchlets are dark bronze green. The habit of the shrub is rampant, climbing, much branched, and very floriferous. The green leafless sprigs of bloom are very serviceable in a cut state for vase decoration, especially if mixed with dry grasses or well-foliaged flowers; the sweet odour, too, reminds one of spring time. Specimens growing against the house or other walls, either nailed or in a trellis, have a happy effect in winter, from the slender whip-like growths hanging down and being well bloomed. From the dark green colour and great number of branchlets, although leafless, a well-grown example has quite the effect of an evergreen.
It enjoys a sunny position, but I have it doing well in a northwest aspect; it may be used in bush form in almost any situation. Neither is it particular as to soil, but I should not think of planting a winter-blooming subject in stiff or retentive loam—that of a sandy nature is more likely to be productive of flowers. It is easily propagated from cuttings of the young wood; if they are taken in late summer, when the leaves are falling, they will root quickly. Before the strong west winds of autumn occur, it should be pruned, in order to prevent its being torn from the wall; if the prunings are laid in sandy loam, between shrubs, they will be sufficiently rooted for planting out by the following spring.
Flowering period, December to April.
Kalmia Latifolia
Broad-leaved Kalmia; Nat. Ord. Ericaceæ
Fig. 56. Kalmia Latifolia.
(One-third natural size.)
An evergreen shrub, very hardy in our climate. It comes from North America, and from its dwarf character and free-blooming habit, it is not only one of the most useful shrubs, but may be freely planted in connection with herbaceous subjects, where it will help to redeem the deadness of beds and borders during winter (see Fig. 56). Like the rhododendron, it grows to various heights, according to the soil or situation in which it may be planted, but 18in. to 2ft. is the size at which it may often—perhaps most often—be seen producing its wealth of flowers. There are many fine flowering shrubs, but they do not gain the esteem in which this is held. Its large clusters of delicate flowers, surmounting dark shining foliage, and which seem almost too pure and beautiful to withstand the vicissitudes of the open garden, are its winning points; moreover, the flowers last several weeks in perfection. The flowers are arranged in broad panicles; the pedicels and five-cleft calyx are a bright brown colour, and furnished with short stiff hairs. The salver-shaped corolla, which is white, pleasingly tinted with red, has a short tube and five divisions, curiously cornered; the flower is fully ¾in. across, and in its unopened state is hardly less pretty than when blown. The leaves are borne on stout woody branches, have short stalks, and a bent or contorted habit; they are thick, leathery, shining, smooth, and of a dark green colour on the upper side; underneath they are a yellowish-green. In form they are elliptical and entire, being 3in. to 4in. long. Healthy specimens are well furnished with foliage; otherwise it is spare, and when that is the case the flowering is rarely satisfactory.
As this subject requires to be grown in moist vegetable soil, such as leaf mould or peat, it is useless to plant it where these conditions do not exist; moreover, the rule with species of the order Ericaceæ is to require a pure, or approximately pure, atmosphere. Doubtless these conditions will debar many from growing this shrub successfully; but I may add, where its requirements can be afforded, not only should it be freely planted, but it will probably thrive without any further care.
As a cut flower it is exquisite, if taken with a good stem and a few leaves; to many it may appear odd when I say it is too good to cut, but there are others who will comprehend me. The flowers can nowhere show to more advantage than on the bush, and it seems a pity to take its strongest branches for the sake of transferring the blossom.
It is a slow-growing subject, but easily propagated by layering the lower branches; no matter how old or hard the wood has grown, if pegged well down they will soon become rooted.
Flowering period, June to August.
Lactuca Sonchifolia
Sow Thistle-leafed Lettuce; Nat. Ord. Compositæ
This is one of the few ornamental species of a somewhat numerous genus; it is, moreover, perennial and hardy in this climate—characteristics not common to the family. It came from Candia, in 1822, since which time it has been grown in English gardens, more or less, as a decorative plant; it is of unusual form, especially in the foliage. I think it would scarcely be called handsome; but the flowers, which are a fine pale blue, and of the form usual to the order, are too good to be overlooked, and their value is enhanced by the fact of their being produced so late in the year.
In speaking of the flower as a subject of the pleasure garden, it is unnecessary to describe it beyond saying that it is of a rich but pale blue colour, and over 1in. across, produced on stalks nearly 2ft. high, in lax panicles. The leaves are large—about 1ft. long and 9in. wide—have a stout midrib, are pinnate, and most curiously lobed. The leaflets, moreover, are fantastically shaped, being again lobed, also toothed and bent in various ways. The teeth have spine-like points, and the only uniform trait about their form seems to be that the edges are turned backwards. The upper surface is a pale green colour, the under side grey, almost white. It is of rather neat habit, and though I have not grown it in lines, it is only needful to see one good specimen in order to be certain of its effectiveness when so planted; it would be singularly distinct.
It enjoys sunny quarters and deep but light or sandy loam. With me it does well on a raised bed of light earth; its long tap roots will save it from drought during the driest summer, when its fleshy and fast-growing foliage would lead one to think that it could not endure a dry time. It is readily increased by division of the roots or seed.
Flowering period, September to strong frosts.
