Hardy Perennials and Old Fashioned Flowers Part 47

(One-tenth natural size.)]

Autumn is the heyday of Composite flowers. The one now under notice has the merit of being of an unusual and beautiful colour, viz., purplish crimson. It is, in fact, a new plant in English gardens, and has been justly described as one of the finest imports of recent years; it has only to be seen in order to commend itself to all lovers of hardy flowers (see Fig. 96). It is a robust grower, ranking with the more n.o.ble subjects suitable for the borders. Its hardiness is doubted by many, and a few have suspected its perennial quality; but notwithstanding the warm climate of South America (whence it hails), it has proved both hardy and perennial in this country. Excessive moisture is its greatest enemy.

Its bright purplish-crimson flowers are daisy-shaped and large, the centre being a fine golden yellow--on strong young plants the flowers will be 3in. across. Moreover, they are numerously produced on stems 3ft. high, in branching cymes, and last a long time in perfection; with favourable weather an individual bloom will stand above a week, and the plant provides itself with abundance of buds for succession. I never yet saw a specimen that developed half its buds, but this brings me to notice one of its faults (for it has more than one), viz., it is too late in blooming; at any rate, in Yorks.h.i.+re we rarely get more than three weeks' enjoyment of its flowers, when, but for severe frosts, it appears capable of blooming for two months. To some extent this may be remedied, as will be shown when I refer to its culture. The radical leaves are over a foot long, stem leaves much smaller, very dark holly green of leather-like substance, the edges very unevenly shaped, the general form of the leaf being something like the cos lettuce.

The cut blooms are indeed fine and cannot well be inappropriately used.

This brings me to fault No. 2. The flower stems are very hollow and dry, nearly as much so as the hemlock or kex, and I have found that when flowers have been cut, either from the moisture collecting in the stem, or some such cause, rot sets in lower down, and soon the branches of bloom head over. I tried cutting to a joint where the cavity was stopped, but the pith when so exposed soon gave way, so that latterly I have ceased to cut the flowers, unless the occasion was worth the risk.

A specimen not cut from did not suffer from stem rot. I, therefore, blamed the cutting. There may, however, be other causes; at any rate, there is the fact of fine flowers in their prime falling over, and it is worth one's while to try to find out from what cause it happens, and if my theory is not the true one, it may prove useful as a hint.

It likes a deep and rich soil, and well deserves to have it; if left out all the winter, a piece of gla.s.s should be put over the crown, because it has the fault (No. 3) of rotting in the centre, as I believe from water being conducted down its spout-like stems; but even under the most neglected conditions it stands our winters, and the rootlets send up a number of small growths in spring. These may make plants, but will not be reliable for bloom the following autumn; the damage should be prevented if possible. Another plan, by which two points are gained, is to grow young plants in good-sized pots and winter them, plunged in cold frames, not failing to give plenty of air. In April these, if compared with others in the open garden, will be found to be much more forward, and the first gain will be that, if planted out then, they will flower much more vigorously, and, secondly, they will start earlier by two weeks at least. To propagate this fine border plant, the very long and fleshy roots may be cut into pieces 6in. long and dibbled into fine soil; they are somewhat slow, but pretty sure to "go"; they should be protected from slugs, which are very fond of the young leaves. On young stuff, grown apart from the flower beds and borders, quicklime may be used, which would otherwise be unsightly.

Flowering period, August to October.

Sisyrinchium Grandiflorum.

SATIN-FLOWER, _or_ RUSH LILY; _Nat. Ord._ IRIDACEae.

[Ill.u.s.tration: FIG. 97. SISYRINCHIUM GRANDIFLORUM.

(One-third natural size.)]

The generic name of this flower is in reference to the grubbing of swine for its roots, and means "pig-snout." The common names may be seen, by a glance at the cut (Fig. 97), to be most appropriate; that of Satin-flower is of American origin the plant being a native of Oregon, and is in reference to its rich satiny blossom; that of Rush-lily, which is, perhaps, an even more suitable name, has been recently applied to it, I believe, in this country. It is applicable alike to the rush-like form and habit of foliage, and the lily-like purity and style of flowers. It was sent to this country in 1826, and yet it is rarely met with in English gardens. Some think it scarcely hardy in our climate in certain soils. I happen to have grown it for six years, which period includes the recent severe winters, and it has not only survived but increased in a moderate degree. This took place on rockwork facing south; in the autumn of 1881 I divided the specimen, and planted a part of it in the coldest part of my garden, which is not without clay, though far from all clay; that division is now a strong plant, and has made an extra crown; it forms the subject of the present ill.u.s.tration.

Let me state, in pa.s.sing, that it is naturally a slow grower. The very severe weather of the week previous to my writing this note, in March, 1883, when 23deg. of frost was registered, which cut down the bloom stems of h.e.l.lebores and many other well-known hardy things, did not hurt this subject very much; I am, therefore, confident of its hardiness from six years of such experience.

The flowers are 1in. to 1in. long, and about as much across when open, of a fine purple colour, with a s.h.i.+ning satiny appearance; the six transparent petal-like divisions are of uneven form, having short bluntish points; from the openness of the corolla the stamens and style are well exposed, and they are very beautiful. The flowers are produced when the plant is about 6in. or 9in. high, the buds being developed on a rush-like stem, and enfolded in an almost invisible sheath 2in. or 3in.

from the apex. Gradually the sheath, from becoming swollen, attracts notice, and during suns.h.i.+ne it will suddenly burst and let fall its precious contents--a pair of beautiful flowers--which dangle on slender arching pedicels, springing from the sheath-socket. They seem to enjoy their new-born freedom, and flutter in the March wind like tethered b.u.t.terflies. Their happy day, however, is soon over; their fugacious petals shrivel in three or four days. The leaves are rush-like, ribbed, and sheathed.

I have found it to thrive in loam, both light and moderately stiff, also in vegetable soil and sand; it likes moisture, but not of a stagnant character; between large stones, at the base of rockwork, suits it in every way; it may also be grown by the side of the larger kinds of snowdrops for contrast and effect. Impatient of being disturbed, it is not wisdom to lift it for any purpose, provided it is making progress, or until it has formed strong tufts; when, if it is desirable to increase it, and during early autumn, the long roots should be got well under, and taken out of the ground as entire as possible; from their wiry nature they are then both easily cleared of earth and divided into single crowns; these should be replanted in positions deeply dug, and where they are intended to remain, being carefully arranged without any doubling up. After such pains have been taken with so well-deserving a plant, there will be little to fear for its future, no matter how severe the winter may prove.

_S. g. alb.u.m_ is a white-flowered variety, of which, however, I have had no experience. Since these lines appeared in serial form, a lady, cultivating a good collection of choice hardy flowers, has informed me that this variety is very fine, and in every way commendable.

Flowering period, March to May, according to positions or climatic conditions.

Soldanellas.

_Nat. Ord._ PRIMULACEae.

Diminutive herbaceous alpine perennials. This genus is small in number of known species as in size of specimens. They are found in very high alt.i.tudes in the Tyrol, Switzerland, and Germany; but they are easily managed even in our foggy climate, as is shown by the fact of the various species being grown in all collections of alpines; and, indeed, no collection can be said to be complete without such gems--they are great favourites, as they well deserve to be. They flower in early spring, some with one, and others more than one flower on a stem.

The flowers are very small, broadly bell-shaped, and of a feathery appearance, from the fact of their petals being finely divided. The foliage is also small, nearly round, of good substance, and in all the following species very bright green; the leaf stalks are long and wiry, and form neat and handsome little tufts, independent of the flowers, which, I may add, do not last more than five or six days.

_S. alpina_, smaller in all its parts, but otherwise much resembling _S.

montana_--has leaves the size of a s.h.i.+lling piece, flowers bright blue, mostly two on a stem.

_S. Clusii_, from Germany, is smaller than _S. alpina_; in other respects similar, with the exception of flowers, which are purple.

_S. minima_ (smallest). Very tiny in all its parts, many of its little thick leaves being only in. across; flowers purple, single on the stem, which is only in. to 1in. long.

_S. montana_ (Fig. 98) is the largest species of all--leaves the size of a half-crown piece, flowers bright blue, four or five on a stem, 5in.

high. It has other distinctions, of a minute character, from the smaller species, but by difference of size alone it may be readily identified.

All the Soldanellas love a vegetable soil, as peat or leaf mould, to which, when under cultivation, a liberal quant.i.ty of sand should be added. If grown in pots, they make lovely specimens, and should be plunged in sand and kept moist; but I find my specimens to grow much more vigorously when planted out, as they are at the base of a small rockery, rather below the level of the neighbouring walk, which forms a miniature watershed for the supply of moisture. I also fancy the liverwort, which surrounds them, rather helps them than otherwise.

Certain I am, however, that moisture is the great desideratum in the culture of this genus. My difficulty with the planted-out specimens is to keep them from being grazed off by the slugs; a dash of silver sand every day or two has sometimes proved of use. When the Soldanellas once get into proper quarters they make rapid growth; I have divided them most successfully in April and May.

Flowering period, March to May.

Spiraea Palmata.

PALM-LIKE SPIRaeA; _Nat. Ord._ ROSACEae.

[Ill.u.s.tration: FIG. 99. SPIRaeA PALMATA.

(One-eighth natural size.)]

A bold and handsome species from China, imported about sixty years ago.

It is perfectly hardy, though, generally grown in pots and under gla.s.s.

It belongs to the herbaceous section, and I may as well state at once that the Spiraeas--more especially the herbaceous kinds--are only decorative when in flower, by which I wish to convey the idea that after they have done flowering, from their abundant foliage, which then begins to turn sere and ragged, they become unsightly if planted in conspicuous parts. Still, their flowers and general habit are both rich and handsome when in their prime, and they are certainly worth growing, especially by those who have large gardens, where they can be planted in large patches in some of the less frequented parts.

_S. palmata_ (Fig. 99) has remarkably bright rosy-crimson flowers; they are of indistinct form unless closely examined. It is, however, a well-known form of flower, or arrangement of flowers, and need not be further described, beyond saying they are in panicles and have a feathery appearance. The leaves, which are 6in. or more across, have long smooth stems, are mostly seven-lobed, the lobes being long, pointed, and unevenly serrated. The size of foliage and height of plants vary very much; if grown in a bog or by the side of a stream, it attains the height of 3ft. to 4ft.; in drier situations I have seen it flower when only 10in. high. The specimen ill.u.s.trated is about 15in. high.

A light spongy vegetable soil, with plenty of moisture, is the main requirement of most of the Spiraeas, and to grow them to perfection little less will do; but a creditable display of bloom may be enjoyed from plants grown in ordinary garden loam, provided the situation is moist. By way of experiment, I planted a dozen roots of this species in an exposed border, drained, and in all respects the same as for the ordinary run of border flowers. They none of them flowered, and scarcely grew; at no time would they be higher than 6in. I wish to make it clear that the Spiraeas, and especially _S. palmata_, cannot be grown and bloomed well without an abundance of moisture at the roots, as I am aware that many have tried and failed with this desirable kind. It should be treated as a bog plant, then it can scarcely fail to do well.

In sunk parts of rockwork, by the walk gutters, by the side of a pond or stream, or (if there is one) in the hedge d.y.k.e, are all suitable places for this bright flower, and if only for the fine spikes which it produces for cutting purposes, it should be grown largely; and as most of the positions indicated are somewhat out of the way, they may perhaps be the more readily thus appropriated. Propagated by division of strong roots during autumn.

Flowering period, July and August.

Spiraea Ulmaria Variegata.

_Syn._ S. ODORATA FOL. VAR.; _Nat. Ord._ ROSACEae.
