Hardy Perennials and Old Fashioned Flowers Part 49

Unless the subject now under consideration can have these conditions, it is useless to plant it--not that its hardiness is doubtful, but because its blooming period should be hastened. Its propagation may be by division of the roots after it has flowered, or in spring.

Flowering period, October to December.

Symphytum Caucasic.u.m.

CAUCASIAN COMFREY; _Nat. Ord._ BORAGINACEae.

A comparatively modern species in English gardens, belonging to a genus well represented by native species, from which this differs mainly in being less tall and hairy, and otherwise less coa.r.s.e. The erect habit, and abundant azure flowers produced in pendent form, which, moreover, last for several weeks, go to make this a capital border plant. If not an old species, from its resemblance to some which are so, it is rendered a suitable companion to "old-fas.h.i.+oned" subjects. The plant grows to a height of nearly 2ft., is of dark greyish-green colour, from being thickly covered with short, stiff hairs, on every part, including the calyx.

The flowers are more than in. long, produced in elongated cl.u.s.ters, opening three or four at a time, and just before expansion they are of a bright rose colour, but afterwards turn a fine blue; calyx five-parted, as also is the corolla, the segments being drawn in at the mouth. The entire flower is long and bell-shaped; the pendent cl.u.s.ters of bloom are well held out from the main stem by leafy branches, each being terminated by two racemes. The leaves of the root are large and stalked, oval, lance-shaped, and wrinkled; those of the stems are stalkless, and so attached as to give the stems a winged appearance near their junction.

The plant will thrive in any kind of soil, but it likes shade and moisture, and a specimen grown under such conditions will be found to be much superior in every way. A position under fruit trees suits it admirably, and for such thoughtful planting it will well repay the lover of flowers for vase decoration. It also makes a good subject for large or rough rockwork, on which, however, it should be sheltered from the mid-day sun. Its propagation may be carried out at any time by dividing the roots, but autumn is the preferable period.

Flowering period, April to June.

Tiarella Cordifolia.

_Nat. Ord._ SAXIFRAGACEae.

[Ill.u.s.tration: FIG. 102. TIARELLA CORDIFOLIA.

(One-fifth natural size; _a_, flower, natural size.)]

The ill.u.s.tration (Fig. 102), together with the order given to which it belongs, will convey a fair idea of the style and habit of the plant, but its exquisite flowers must be seen to be appreciated, and hardly could they appear to more advantage than in a growing state, the rich foliage forming their most natural and effective ground. This hardy herbaceous perennial has been known to English gardens for 150 years, and was introduced from North America, where it grows in glorious ma.s.ses, but common as it is in its native country, and long as it has been grown in this, I scarcely know a flower respecting which so many have been in error as regards the true species. I have had all sorts of things sent to me under the name, and, after all, it is easy to be wrong with it unless the amateur has either closely noted its distinctions or grown it for a year at least. Heucheras are similar in habit and shape of foliage, and are often confounded with it, though otherwise very distinct. _Tellima grandiflora_, when in its young state, is very like it, but the strong crowns should be noted--they are twice the strength of _T. cordifolia_, and develop foliage more than double its size, whilst the flowers are on stems 3ft. high, nearly green, and might easily be taken for seed pods.

The Mitellas, however, are much more puzzling, the distinctions being finer and mostly of a botanical character. Still, in May and June, when all are in flower, the identification of our subject is not difficult, more especially if the other species of the same order are near for comparison.

_T. cordifolia_ grows to the height of 9in. to 12in.; the flowers are composed of a calyx (five-parted) and five petals, which are entire, evenly set in the calyx. The ten stamens are prominent; each flower has a stout pedicel, which holds out the pretty white blossom in a nearly horizontal way. There is nothing of a bell-shape character about the flower, as in its nearest relative the Mitella. The flower stem is erect and round, being evenly furnished with flowers, for a length of 4in. to 6in.; the flowers are very lasting. The leaves are heart-shaped, acutely lobed, denticulate, slightly wrinkled, hairy on both sides, and more or less spotted or splashed with brown spots on the main ribs; the leaf stalks are long, and carry the foliage gracefully. The whole plant has a neat habit, and, when in vigorous health, sends out surface creepers.

It enjoys moist quarters and slight shade, though it is grown as seen in the drawing in an exposed part. The soil is good, but otherwise there is nothing special about its culture. If this little spring flower can be made more known, it will be sure to be more widely cultivated; for covering the bare parts of lawn shrubberies it would form a pleasing subject, and might be mixed with the scarlet ourisia and the finer sorts of myosotis; these would make an excellent blend, all flowering together, and lasting for a long time, besides being suitable otherwise for such shady positions. When increase is desired strong plants may be divided at any time, soon after flowering being the best; if the season be dry, the young stock should be shaded by a leafy branch and kept well watered.

Flowering period, May and June.

Trientalis Europaea.

EUROPEAN WINTERGREEN, or STAR-FLOWER; _Nat. Ord._ PRIMULACEae.

Some may say, "Why, this is a common British plant;" and so it is in some parts, but for all that there are many who have never seen it. In no way does the mention here of this lovely little flower need an apology: the best possible reasons for growing and recommending it are in the facts that it is very beautiful and greatly admired (see Fig.

103).

[Ill.u.s.tration: FIG. 103. TRIENTALIS EUROPaeA.

(Plant, one-third natural size; blossom, full size.)]

The flowers, which are in. across, are salver-shaped, pure white, excepting for a day or two when newly opened, then they are stained with a soft pink; the calyx has eight handsome light green, s.h.i.+ning, awl-shaped sepals; the corolla has five to nine petals, equal in size, flatly and evenly arranged, their pointed tips forming the star-like appearance from which the flower takes one of its common names; the flower stalks are exceedingly fine--thready--but firm, from 1in. to 3in.

long, and each carries but one flower; they issue from the axils of the leaves, which are arranged in whorls of five or seven, and nearly as many blossoms will be produced from the whorl, but seldom more than one, and hardly ever more than two, flowers will be open together, when they occupy the central position of the foliage, which gives the plant an elegant appearance. The leaves are of a pale green colour, sometimes a little bronzed at the tips, veined, entire, bald, lance-shaped, and, as before hinted, verticillate; they vary much in size, being from 1in. to 3in. long and in. to 1in. broad. The stems are round, reddish, slender, and naked, with the exception of two or three minute round leaves, borne distantly apart; the stems, too, like the leaves, vary in length; sometimes they grow 8in., while others equally floriferous are not above 3in. high; the root is creeping, and somewhat tuberous. A colony of this plant has the appearance of a miniature group of palms, bedecked with glistening stars at the flowering time, and it is one of the most durable flowers I know; so persistent, indeed, are they, that botanical descriptions make mention of it.

In a cut state they equal either violets or snowdrops, from the beautiful combination of flowers and foliage, and it is a pity that it is not grown in sufficient quant.i.ties for cutting purposes. Its culture is very easy, but to do it well it may be said to require special treatment; in its wild state it runs freely, and the specimens are not nearly so fine as they may be had under cultivation with proper treatment. It should have moist quarters, a little shade, light vegetable soil, and confinement at the roots. I ought, perhaps, to explain the last-mentioned condition. It would appear that if the quick-spreading roots are allowed to ramble, the top growths are not only straggling, but weak and unfruitful. To confine its roots, therefore, not only causes it to grow in compact groups, but in every way improves its appearance; it may be done by planting it in a large seed pan, 15in. across, and 4in. or 6in. deep. Let it be well drained; over the drainage place a layer of lumpy peat, on which arrange another of roots, and fill up with leaf soil and peat mixed with sand; this may be done any time from September to February; the pan may then be plunged in a suitable position, so as to just cover the rim from sight, and so do away with artificial appearances; but if it is sunk too deep, the roots will go over the rim and all the labour will be lost. So charming is this plant when so grown, that it is worth all the care. A well-known botanist saw such a pan last spring, and he could hardly believe it to be our native species. Pans at two years old are lovely ma.s.ses, and very suitable for taking as grown for table decoration. The outer sides of the pans should be banked down to the tray with damp moss, which could be p.r.i.c.ked in with any soft-coloured flowers, as dog roses, pinks or forget-me-nots.

I will only add that, unless the root confinement is effected either in the above or some other way, according to my experience, the plant will never present a creditable appearance as a cultivated specimen; at the same time, this somewhat troublesome mode of planting it is not in proportion to the pleasure it will afford and certainly ought not to prevent its introduction into every garden.

Flowering period, May and June.

Trillium Er.e.c.t.u.m.

ERECT WOOD-LILY; _Nat. Ord._ MELANTHACEae.

[Ill.u.s.tration: FIG. 104. TRILLIUM Er.e.c.t.u.m.

(One-half natural size.)]

A hardy, tuberous perennial, from North America, whence most, perhaps all, the species of this genus are imported. The peculiar form of the plants gives rise to the generic name. A flowering specimen has on one stem three leaves, three sepals, and three petals; the specific name is in reference to the more erect habit of this species compared with others. Of _T. er.e.c.t.u.m_ there are several varieties, having different-coloured flowers; the specimens from which the drawing (Fig.

104) was taken have rich brown or dark maroon flowers. Little groups have a rather quaint look, they being very formal, the flowers curiously placed, and of unusual colour. The flowers are fully 2in. across, or much more, if the petals did not reflex almost their whole length. The sepals of the calyx are exactly alternate with the petals, and remain erect, giving the flower a characteristic quality; and, let me add, they are far more pleasing to the eye than to the sense of smell. The leaves are arranged in threes on the main stem, and that number const.i.tutes the entire foliage of the plant; they are stalkless, oval, but pointed, entire, smooth, and of a s.h.i.+ning dark green colour. The specimens from which the ill.u.s.tration was made are 5in. to 6in. high, but their height differs very much with the positions in which they are grown, shade and moisture inducing taller growths. The roots, which are tuberous, are of unusual form--soft swollen root-stocks may be more descriptive of them. Trilliums are now in much favour, and their quiet beauty is likely to create a genuine love for them. Moreover, the different species are distinct, and if grown in cool, shady quarters, their flowers remain in good form and colour for a long time. They are seen to most advantage in a subdued light, as under the shade of rather tall but not too thickly grown trees. They require vegetable soil, no matter how light it may be, provided it can be maintained in a moist state, the latter condition being indispensable. Trilliums are capable of taking a good share towards supplying shade-loving subjects. How finely they would mix with anemones, violets, _Paris quadrifolia_, h.e.l.lebores, and such like flowers! Colonies of these, planted so as to carpet small openings in shrubberies, would be a clear gain in several ways to our gardens; to many they would be a new feature; more showy flowers would not have to be given up for such an arrangement, but, on the other hand, both would be more enjoyed by the contrast. Trilliums increase slowly; propagation may be carried out by the division of the roots of healthy plants.

Flowering period, May and June.

Triteleia Uniflora.

_Sometimes called_ MILLA UNIFLORA; ONE-FLOWERED TRITELEIA, _or_ SPRING STAR FLOWER; _Nat. Ord._ LILIACEae.

This is a favourite flower, and in some soils increases very fast; it is the commonest species of the very limited genus to which it belongs; was brought from South America only so recently as 1836, and it is already extensively grown in this country, and as a trade article is very cheap indeed, thanks to its intrinsic worth. Though small, its star-like form gives it a lively and effective appearance in the borders. It is much used by the Americans as a window and greenhouse plant, notwithstanding that it is a wild flower with them, and its pretty shape and lovely hues render it eligible for such uses, but on account of the esteem in which is held the odour of garlic, I should not like to recommend it for such close a.s.sociations. The flower in shape is, as the generic name implies, like the Trillium, formed of three, or rather threes; the divisions are arranged in threes, or triangularly; the two triangles, being crossed, give the flower a geometrical and star-like effect. The flowers, which are 1in. to 2in. across, are borne on slender stems, 4in.

to 6in. long. They are nearly white, but have various tints, bluish reflections, with a line of blue in each petal. The leaves resemble those of the snowdrop when overgrown and turning flabby, and have a somewhat untidy and sprawling habit; they are abundantly produced from the rather small coc.o.o.n-shaped bulbs. On the whole, the plant is very ornamental when in flower, and the bloom is produced more or less for many weeks; at any rate, it is an early flower, and if it cannot be used indoors it should be extensively planted amongst border subjects, than which there are few more hardy or reliable. Propagated by divisions of the crowded bulbs every other year, during late summer.

(One-fourth natural size.)]

_T. u. lilacina_ (the Lilac-coloured Star Flower) is a most handsome variety, having, as implied by the name, a richly coloured flower. I am indebted to a lady for roots and flowers recently sent me; so far as I know, it is not yet generally distributed. It is very distinct from the type in having smaller parts throughout, and a more highly coloured bloom, with the outer surface of the s.h.i.+ning tube of a darker or brownish-green colour. I have seen a mauve coloured form, but this is much more p.r.o.nounced and effective. The chief recommendation of this otherwise desirable flower, to my thinking, is its rich, new-mown hay scent; in this it differs much from the parent form.
