Hardy Perennials and Old Fashioned Flowers

As a cut bloom, the Christmas Rose vies with the eucharis and pancratium. For vase work, or used about the person, it is a flower that wins the greatest admiration, and it is no unusual thing for cut flowers to last indoors quite a fortnight.

H. n. angustifolius (narrow-leaved Hellebore) has smaller flowers than the type. The divisions of the leaves or leaflets are narrower, whence its name. The foliage is of a pale or apple green, whereas that of the type is very dark. It was introduced in the same year as its reputed parent. As a foliage plant it is very handsome, the leaves bending gracefully, and the whole specimen having a neat appearance.

H. n. maximus is the largest Christmas Rose, and is a truly grand variety; the flowers are 4in. and 5in. across. The illustration (Fig. 49) is one-fourth natural size. The scapes are very stout, and produce several flowers, which are held well above the foliage; like those of the type, they, too, are tinted with a pink colour, which passes away when the flowers are a week or so old. The foliage is remarkably bold, having thick, round, and beautifully marked stalks. Well-established specimens have a shrub-like effect, being nearly 2ft. high, and richly furnished to the ground. The half-blown buds of this variety are exquisitely beautiful, and vary somewhat in form according to their age; some resemble a nearly blown tulip, and others a rosebud. As buttonholes, backed with a frond of maidenhair, they are charming. A whole scape, having one fully-blown flower and several buds, is the most perfect and beautiful decoration imaginable for a lady's hair. This variety is at its best in the month of December, being a little earlier than the typical form.

(One-quarter natural size.)

All these kinds should be grown in moist and rather shady quarters; under trees not too densely foliaged will suit them; the soil should be a deep rich loam. I may mention that all my Hellebores are grown under "nurses," i.e., suitable small trees. I use walnut. About eighteen species and varieties are planted under six small trees, 4ft. high. The reasons why I use walnut are, that they leaf late in spring and lose their leaves early in autumn, so affording the greater amount of light during the flowering time of the Hellebores, and screening them in summer from the sun with their ample but not over thick foliage; a cut under the trees once a year with a sharp spade keeps them dwarf and prevents their making too many strong roots. Without saying that Hellebores should be grown in this way, it will serve to show how they may be conveniently shaded. Nothing could well look more happy under such treatment, and, once properly planted, they give no further trouble than a mulching of rotten manure in spring, when all the kinds have finished flowering. Christmas Roses are easily raised from seed, provided it is sown as soon as ripe, but plants so raised are two or three years before they flower. The quicker method of increase is by division of the roots. This can only be done successfully when the old stock is in robust health. Pieces of roots taken from old and unhealthy specimens will remain in the ground for twelve months as immovable as stones, whereas the least bits of clean young growths will form nice blooming plants the first year.

Flowering period, December to March.

Helleborus Odorus

Sweet-scented Hellebore; Nat. Ord. Ranunculaceæ

Like all the Hellebores, excepting the white-flowered H. niger and its varieties, this has, until very recently, been much neglected, notwithstanding that its name implies the rare and desirable quality of a sweet odour; moreover, it is of easy culture, very hardy, and a free bloomer. It is a native of Hungary, and was introduced to English gardens in 1817. It is like H. purpurascens, only its flowers are green; it even more strongly resembles our native H. viridis. All its foliage is renewed annually. It belongs to the section having stems few-flowered, forked, and bearing floral leaves. It grows 9in. to 12in. high.

The flowers are green, small, nodding, and scented. The sepals are nearly round, and overlap each other. The flowers are produced at long intervals on the twice-branched, stout, pale green stems; they are supported by prettily-cut leaves, having lance-shaped segments, finely serrated, also having large stipules. The radical leaves are palmate, covered with a fine down on the under surface. The segments are oblong, undivided, and at the base quite entire, but finely toothed near the top. The bloom lasts a long time, either cut or in the growing state. There is nothing very distinct to the eye about this species, but it is to be commended for the sweetness of its flowers.

Like other Hellebores, it should be grown in a shady place, where there is a good depth of rich sandy loam. Propagated by division of healthy stock at almost any period.

Flowering period, February to March.

Helleborus Olympicus

Olympian Hellebore; Nat. Ord. Ranunculaceæ

This comes from a Grecian habitat, as the specific name denotes; still it is perfectly hardy in this climate, and it deserves a place in every garden. It is not so old in English gardens as some kinds, and may not be much known; at any rate, it is seldom met with; but, from the fact of its coming into bloom in the first month of the year, and having finely-formed purple flowers, it is a desirable companion to the white Christmas Rose; it is variously stated to have white and purple flowers, both statements being authorised; they are produced in spare clusters on stems a foot high; the buds are charming objects, of a ruddy-brown colour, and the size of a big filbert; they are rather close together, and supported by a "cut floral leaf." The leaves are well divided and almost palm-shaped, the leaflets being ovate and toothed. It is a free grower, and never fails to bloom well too.

Cultivation and flowering period, the same as with H. niger.

Helleborus Orientalis

Eastern Hellebore; Nat. Ord. Ranunculaceæ

Sometimes also called the Lenten Rose, as it may often be seen in flower during Lent, though it is no uncommon thing for it to bloom in January in favoured situations and mild winters. This is a very old species which has long been known to botanists, but it has only recently been introduced into this country. It is a native of the Levant, is plentiful on mountains and near Thessalonica and Constantinople. It has gone under the name of H. officinalis, and as such was, as it still is, the shop Hellebore of the East. As a garden flower it is to be recommended as one of the best of the genus; the colour is often a fine rose variously tinted, and the blooms are of good size. It is, however, a species respecting which there is still considerable misconception. One authority says the leaves die off and again appear with the flowers; another classes it with the group "leaves not annually dying"; then one says, "the greenish-white blossoms are tinted at the margin with purple"; another, that the flowers are "rose-coloured"; whilst botanical descriptions, usually so taunting to the florist as regards blossom-colour, are no exceptions in this case. "Sepals oval, coloured," does not point out very clearly the information desired. Many of the species of Hellebore are known to produce flowers varying more or less in colour; and we also know that an individual blossom, during the long period in which the sepals keep good, often changes its tints and colours, but we are scarcely prepared to hear that a species has greenish-white flowers, whilst we have always seen a rosy or rosy-purple one produced. Still, the information from another source, that H. orientalis is a species intermediate between H. niger and H. viridis, would seem to favour the greenish-white as the typical colour; be that as it may, it is most likely that the more desirable rosy-flowered variety will prevail in flower gardens, that being the general recognised colour of the type, and moreover, one which renders it pleasingly distinct in the whole genus. There are hybrid kinds which have been raised from this species crossed with H. viridis and, perhaps, others, and some of them have greenish-white flowers; but they should not be confounded with the species under notice. These varieties have received such names as H. orientalis elegans, H. o. viridescens, and H. o. punctatus. If hybrids are to be honoured with specific names, it will require much care to avoid confusion, and it is just possible that some such causes have led to the various descriptions above referred to. The type under notice is fairly distinct, and the amateur having a slight acquaintance with the Hellebore family will have little difficulty in making it out.

The flowers are produced on forked stems, and are accompanied by finely-cut floral leaves, nearly sessile and palmate; the radical leaves are large, pedate, downy underneath, having long stalks, and remaining green throughout winter. The habit is to push the stout flower stems well up above the foliage, sometimes as high as 18in.; the flowers are very durable, at least the major parts—as the sepals—are, the stamens and petals falling somewhat sooner than those of most species; if different positions are given to a few specimens, flowers may be had from Christmas to Lent, according to amount of shelter or exposure therein obtained for the plants.

There are facts connected with this plant, as other than a garden subject, which can hardly fail to be generally interesting. "This is the Black Hellebore of the ancients," so that, though H. niger bears the name and is known to be largely possessed of properties similar to those of the oriental species, it is proved to be wrongly applied. So much was claimed by ancient doctors for the Black Hellebore as a medicine in mania, epilepsy, dropsy, and other ills to which mortals are heirs, that naturally the true plant was sought with much zeal. Dr. Woodville laments the want of proper descriptions of plants and the consequences, and in his "Botany," p. 51, points out some ridiculous errors made in reference to the Black Hellebore previous to 1790; he gives the names of many plants which had been mistaken for it and actually employed, and he assumes that at the time of his writing all such errors had not only been discovered, but corrected, by what he then described as, and we now call by the name of, H. niger, being the true Black Hellebore; and after all, the potent herb of the ancients has been identified in a plant (a near relation, it is true) other than the white Christmas Rose—it may be some time before we come to think of our present subject as the true Black Hellebore, especially when an otherwise popular species bears the name.

Cultivation, as for H. niger.

Flowering period, December to April.

Helleborus Purpurascens

Purplish Hellebore; Nat. Ord. Ranunculaceæ

A native of Podolia and Hungary, introduced sixty to seventy years ago. It belongs to the section whose flowers appear before the root leaves, having branched flower stalks and the cut floral leaf. It is a dwarf kind, and varies very much; I have now an established specimen in bloom at the height of 3in., and others at 8in. or 9in. It also differs in the depth of bloom-colour; some of its flowers may be described as purplish-green and others as greenish-purple, slaty and dove-coloured; others have a tinge of red more visible. The flowers are few, on twice-forked stems, are 2in. or more across, and commonly, as the name implies, of a purplish colour; the inner surface of the sepals is a slaty shade, the purple prevailing on the outer surface; the form of the flower is nearly round and slightly cupped, from the nearly round or kidney shaped sepals, which neatly overlap each other, and are also incurved at the edges; the petals are very short and green; the stamens and anthers of a creamy white; the floral leaf is nearly stalkless; segments unevenly toothed. The radical leaves are "pubescent on the under surface, palmate, with the segments cuneated at the base, and from three to five lobed at the apex." The habit is robust and free blooming; the flowers slightly droop, and, though the colours are not showy, they are attractive from the way in which they are borne on the straight stems and the absence of the larger leaves. It is a desirable species for the garden; a few specimens grown amongst a mass of the "winter aconite" are enough to make one forget that it is winter.

Cultivation, as for H. niger.

Flowering period, February to April.

Hepatica Angulosa

Nat. Ord. Ranunculaceæ

This is a very distinct species. It comes from North America, and is twice the size of H. triloba in all its parts; the leaves are more cut, and very woolly; the flowers are bright mauve, and 1½in. across. All the Hepaticas are slow growers, but H. angulosa is the more vigorous. Some say they should be grown in peat, but I never saw them so fine in peat as in strong loam, well drained and manured; they are the better with slight shade. I do not object to peat, as possibly it may be more suitable than the natural soil of some gardens. Still, if I had to make up a compost for Hepaticas, I should freely use strong loam on a well-drained site. With me they have been in flower nearly three months, commencing in February.

It seems desirable to increase these fine spring flowers, but they are most impatient of being disturbed, and, after all, the increase can exist in no finer form than in big clumps, though when they are to be propagated the roots should be divided before the new leaves are produced, which is during the blooming period. A deeply-dug and well-manured plot should be prepared for them, and their long roots should not be doubled up in the least; they both need and deserve great care.

Flowering period, February to April.

Hepatica Triloba

Syns. Anemone Triloba and Anemone Hepatica; Nat. Ord. Ranunculaceæ

Fig. 50. Hepatica Triloba.

(One-third natural size.)

The well-known common Hepatica, of which there are so many beautiful varieties. It is a hardy perennial, one of the "old-fashioned" flowers of English gardens, and is said by some to be a British species; anyhow, it was well known and admired in this country 300 years ago. Well-established specimens form neat tufts of three-lobed leaves on long stems, which are not evergreen in this climate, though the Hepaticas are known to be so in North America, one of their most extensive habitats. Here, under cultivation, they produce much finer flowers, and more of them. The cut (Fig. 50), however, shows the foliage in more perfect form than it is commonly seen to be in this climate during the period of bloom, when the old is usually sered, and the new scarcely visible. The varieties of H. triloba differ only in the colour and form of their flowers, there being blue, purple, white, and pink. Of the first and last named there are double varieties as well.

Cultivation, the same as for H. angulosa.

Flowering period, February to April.

H. t. splendens is a charming Windflower, and one which, from its extra brilliancy, is sure to become a favourite, as, indeed, the whole genus Anemone is. It is a new variety of H. triloba, and is yet somewhat scarce, differing from the more generally known kinds of the same species in only two points, so that, beyond the mention of them, no other description is needful: (1) Its flowers are single red, but so much deeper in colour, brighter, and of better substance, as to be quite distinct, and merit the name "splendens." (2) It flowers earlier than the commoner red kind. This handsome seedling of the common Hepatica is very suggestive of what can be done by raising seed from carefully-selected sorts, and within the last few years something has been done in that direction, so that in a little time we may expect to see other good varieties. I may add that seedlings are three years before they bloom, and even longer before a proper idea can be formed of their qualities.

Cultivation, the same as for H. angulosa.

Flowering period, February to March.

Hesperis Matronalis Flore-pleno

Double Sweet Rocket, or Dames' Violet; Nat. Ord. Cruciferæ

There are several double forms of this very popular old flower, such as purple, ruby, and pure white, the last named being by far the greatest favourite. A few years ago it was said to be very scarce, and in some parts of the country it certainly was so, but when the present taste for the good old flowers became general, it was not only found, but quickly propagated, so that now the double white Sweet Rocket may be had everywhere, and certainly no more beautiful flower can occupy the garden borders, its perfume being strong and deliciously fragrant. The parent plant of these double kinds is widely distributed over Europe; all are perfectly hardy.

They vary in height from 12in. to 18in., branching candelabra-like, the flowers being produced in terminal spikes, arranged in the way of, and very much resembling, the double stocks—in fact, the Hesperis used to be called "Queene's Gilloflower." The leaves may be briefly described as oval, lance-shaped, toothed, and veined; dark green, and often spotted or blotched. Gerarde's description, too, may be given, as it is always pleasant to recognise the old plants of 300 years ago: "Dames' Violets hath great large leaues of a darke greene colour, somewhat snipt about the edges; among which spring up stalks of the height of two cubites, set with such like leaves; the flowers come foorth at the toppe of the branches—like those of the Stock Gilloflower, of a verie sweete smell."

These desirable flowers have a long blooming period, and their cultivation is simple; there is, however, one special point to be observed, otherwise these double kinds will die off. It should be remembered that they produce no seed, and propagation must be carried out by divisions of the roots and cuttings; old plants, too, have a habit of forming their perennial crowns nearly out of the soil, so that the roots going down from them are often bare and unestablished; the older parts, too, are frequently attacked by ground vermin. No doubt these causes would tend greatly to the former scarcity of the finer kinds, but all the difficulties, if they can be called such, may be overcome by the very simple process of either putting in cuttings like wallflower slips during summer, or, as soon as the old plants are past their best bloom, dividing and replanting the various parts deeper, whereby all of them, however small, will make good plants the following season.

This mode of keeping up the stock will be found to make the plants vigorous and free blooming, and also will prove a remedy for the complaint so often given expression to in such words as "I lost all my double Sweet Rockets; I cannot keep them above two years."

Flowering period, June to August.

Heuchera

Alum-root; Nat. Ord. Saxifragaceæ

This is a small genus of hardy perennials suitable for the decoration of the English garden from their bold and finely-shaped leaves, which are well marked with various pleasing tints, also because of their perpetual verdure and neat habit. It takes its name from J. H. de Heucher, a botanist. The species, as many of them as are known, are from American habitats; nearly all have been introduced within the last sixty years; the well-known H. Americana, however, is an old plant in English gardens, having been cultivated for 223 years. The order, as given above, together with the illustration figuring one of the species (see Fig. 51), will give some idea of the usefulness of the genus, especially when it is remembered that in the depth of winter the foliage is fresh, and even in a growing state.

The flowers are of little value for ornamental purposes; they are very small and numerous, and are arranged in panicles or racemes, on rather tall and mostly leafless stems, round, and somewhat wiry; calyx, petals, and stamens have a mixed appearance, the whole flower being of a dingy colour, often resembling some of the panicled bloom of meadow grass, when seen at a short distance; the calyces, however, are persistent, they crown the capsules; these and the naked stems, from their durable nature, mar the beauty of the foliage for several weeks, unless cut off. The plants are more ornamental without the flowers, as they impart a seedy appearance; at no time does the foliage show to more advantage than in January, when most herbaceous plants are dormant, and when their handsome tufts are alike beautiful, either bedewed with fogs, crystallised with hoar-frost, or glittering in the sunshine. As a genus, Heuchera is sometimes placed after Saxifraga and before that of Tiarella; the latter it much resembles, as well as the genera Mitella and Tellima. Anyone knowing these will at once admit the usefulness of the plants under notice.

Not only do they make good edgings or lines to borders, but the leaves in a cut state are of great service for table decoration, doing duty repeatedly around dishes, &c., either with or without flowers; after being so used, if placed in water, they may be kept a fortnight in good form. I am told that the leaves are sold in Covent Garden Market for similar purposes. I have seen them used in the autumn with the large white anemone, and in winter with the Christmas rose, one flower arranged and tied on the face of a single leaf. These placed round dishes, &c., have a pretty effect.

They grow freely in any kind of soil, excepting stiff clay, and are readily increased by division of the crowns. This may be done any time, but, perhaps, spring is the best.

The Heucheras bloom from May to August.

Heuchera Americana

American Heuchera; Nat. Ord. Saxifragaceæ

The flowers of this species are a dull or reddish purple. The foliage is rough and clammy; the form of leaf resembles that of H. glabra (see Fig. 51), but the colour is a lighter green. All the genus are of an astringent nature, but this species is remarkably so, and in its native country has earned for the family the name of "Alum-root."

For cultivation and flowering period see Heuchera.

Heuchera Cylindrica

Cylindrical-spiked Heuchera; Nat. Ord. Saxifragaceæ

This is much in the way of H. Richardsoni, with the distinction indicated by the name, the flowers being arranged evenly round the spike like a cylinder.

For cultivation and flowering period see Heuchera.

Heuchera Drummondi

Drummond's Heuchera; Nat. Ord. Saxifragaceæ

A tall kind, with leaves of handsome shape (heart-shaped and lobed) and greener than most varieties.

Cultivation and flowering period are described under Heuchera.

Heuchera Glabra

Smooth Heuchera; Nat. Ord. Saxifragaceæ

Fig. 51. Heuchera Glabra.

(One-sixth natural size.)

This was introduced in 1824 from North America. The foliage is bold and abundant; the illustration (Fig. 51) not only gives a good idea of the form and habit of foliage, but fairly represents the whole genus, as seen during the late (1882) season. This species has dull pinkish flowers; the scapes have a few leaves; root leaves are 2in. to 5in. in diameter, heart-shaped, lobed, toothed, smooth, and of a dark bronzy-green colour. The leaf stalks are long and slender; the habit very neat.

Cultivation and flowering period are described under Heuchera.

Heuchera Lucida

Shining-leaved Heuchera; Nat. Ord. Saxifragaceæ

A very dwarf species, not more than 3in. or 4in. high; the foliage a clear bright green, nearly kidney-shaped, lobed, and roundly toothed. The fresh appearance of its prostrate leaves, which are 2in. across, forms a pleasing object in mid-winter.
