Hardy Perennials and Old Fashioned Flowers Part 27

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-fas.h.i.+oned" 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 Correaefolia.

_Nat. Ord._ CRUCIFERae.

This is a hybrid and much improved variety of the well-known evergreen and shrubby Candytuft, often called "Everlasting Candytuft." A more p.r.o.nounced 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 ma.s.ses 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 subst.i.tute for a gra.s.s 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 cl.u.s.ter 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 s.h.i.+ning green colour; in length 1in., and over in. 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 proc.u.mbent.

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 quant.i.ty, as for church decorations. _I. correaefolia_ 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 ma.s.ses 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 Foetidissima.

GLADDON, GLADWIN, _or_ SPURGE-WORT; _Nat. Ord._ IRIDACEae.

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._ RANUNCULACEae.

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 cla.s.sed with the maidenhair-like rues, and the ill.u.s.tration may be said to give a fair idea of three or four species.

[Ill.u.s.tration: 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._ JASMINACEae.

[Ill.u.s.tration: 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 mid-winter, 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 gla.s.shouses 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 s.h.i.+ning; the flowers last a long time, even during the roughest weather, they open most during suns.h.i.+ne, 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 gra.s.ses 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._ ERICACEae.

[Ill.u.s.tration: 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 cl.u.s.ters of delicate flowers, surmounting dark s.h.i.+ning 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 in. 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, s.h.i.+ning, 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.
