Hardy Perennials and Old Fashioned Flowers

Bulbocodium Trigynum

Syns. Colchicum Caucasicum and Merendera Caucasicum; Nat. Ord. Melanthaceæ

This pretty miniature bulbous plant is very hardy, flowering in winter. It is a scarce flower, and has recently been represented as a new plant. As a matter of fact, it is not new, but has been known under the above synonymous names since 1823, when it was brought from the Caucasus. In general appearance it is very different from the Colchicum (Sprengle), as may be seen by the drawing (Fig. 21), and Merendera (Bieberstein) is only another Spanish name for Colchicum. The new name, authorised by Adams, may have been the cause, all or in part, of its being taken for a new species. The specific name may be presumed to be in reference to either its deeply-channelled, almost keeled leaves, which have the appearance of three corners, or in allusion to the triangular way in which they are disposed. It is a desirable flower for several reasons—its earliness, durability, rich perfume, and intrinsic beauty.

Fig. 21. Bulbocodium Trigynum.

(Full size.)

The little plant, at the height of 2in., produces its rather large flowers in ones and twos in February, and they last for many days in perfect form. The scent reminds one of the sweet honey smell of a white clover field during summer. The colour is very pale lilac, nearly white; the tube takes on a little greenness; it is also divided, though the slits are invisible until the bloom begins to fade. The corolla, of irregular segments, is 1½in. across when expanded; the stamens are half the length of the petal-like segments, and carry anthers of exquisite beauty, especially when young, then they are orange colour, divided like a pair of half-opened shells, and edged with chocolate; the styles are a delicate pale green, and rather longer than the stamens. The leaves, as already stated, are channelled, broadest at the base, tapering to a point, which is rather twisted; they are 2in. long during the blooming period, of a deep green colour, stiff, but spreading, forming a pretty accurate triangle. This description, together with the cut, will suggest both the uses and positions in which it should be planted; if a single blossom, when brought indoors, proves strongly fragrant, it is easy to imagine what a clump must be in the garden. Like those of the colchicum, its flowers are quickly developed; the leaves grow longer afterwards, and die off in summer.

It thrives in a sandy loam or leaf soil, in a sunny part, and increases itself at the roots like the saffrons.

Flowering period, February and March.

Bulbocodium Vernum

Spring Bulbocodium, or Spring Saffron; Nat. Ord. Melanthaceæ

In mild winters, sheltered positions, and light vegetable soil, this bulbous plant may be seen in blossom from January to March. The flowers appear before the leaves, and may, at the first glance, be taken for lilac-coloured croci. Up to a certain stage, however, the colour gradually improves in the direction of purple, and where there are established patches it is no inconsiderable part of the effect caused by this desirable winter flower to see it a mass of bloom in many shades, ranging from white (as in the bud state) to a lively purple. It is an old plant in English gardens, and is largely found wild in mid-Europe. It came from Spain as early as 1629. Still, it is not generally known or grown; but within the last few years it has come to the fore, with a host of other hardy and early-flowering subjects. The natural order in which it is classed includes many beautiful genera, both as regards their floral effect and anatomical structures. Veratrum, Uvularia, and Colchicum are, perhaps, the more familiar, and the last-mentioned genus is a very nearly allied one. A feature of the genus Bulbocodium is implied by the name itself, which means "a wool-covered bulb." This quality, however, will be more observable when the bulb is in a dormant state; it exists under the envelope. The crocus or saffron-like flowers are aptly named "Spring Saffron," though there is a great botanical difference to be seen between this genus and that of Colchicum when the flower is dissected. The bloom is produced from the midst of an ample sheath, and overlapping leaves, which are only just visible in the early season of this year; the corolla of six petal-like divisions is 2in. to 3in. across when expanded, and of various shades and colours, as already stated; the segments are completely divided, being continued from the throat of the corolla to the ovary by long tapering bases, called nails, claws, or ungues. The leaves are stout, broadly strap-shaped, channelled, and of a deep green colour. The bulb is rather small; its form resembles that of the autumn crocus, as also does its mode of growth and reproduction.

The early blossoms of this bulb soon disappear, and though the roots are all the better for being well ripened, a thin patch of some of the finer annuals sown in spring amongst their withering leaves will not do much harm, and will prove useful as gap-stoppers. Another good way is to grow these dwarf bulbous flowers with a carpet of creepers, of which there are scores in every way suitable; and where nothing else is available or to be grown with success, the small-leaved ivy will answer well. The dwarf phloxes, however, are more useful; their browned spreading branches form a neutral but warm-looking ground to the purple blossoms; besides, by the time all trace of the Bulbocodium has shrivelled up, they begin to produce their sheets of bloom. All such prostrate forms not only preserve dwarf winter flowers from the mud, but otherwise give effect to the borders. This bulb thrives best in light soil, well drained; in sheltered nooks it may be had in flower a month earlier than in exposed parts. Under such conditions it increases very fast, and the bulbs may be transplanted with advantage every other year after the tops have died off. In stiff or clay-like soil it dwindles and dies.

Flowering period, January to March.

Calthus Palustris Flore-pleno

Double Marsh Marigold; Old Common Name, "Meadow Bootes"; Nat. Ord. Ranunculaceæ

The typical, or single-flowering variety of this plant is a British species, and a rather common one; but the pleasing habit and bright, finely-formed, orange-yellow flower of this double kind renders it a suitable plant for any garden. It is herbaceous and perennial, and loves boggy situations. It is, however, very accommodating, and will be found to do well in ordinary garden soil, especially if it be a stiffish loam; clayey land is well adapted for it. No matter what kind of weather prevails, it has always a neat and fresh appearance. By the illustration (Fig. 22) the reader will doubtless recognise its familiar form. As already stated, its flowers are orange-yellow, very full, with petals evenly arranged; they are 1in. across, and produced on round, short, hollow stems, seldom more than 9in. high. The forked flower stalks are furnished with embracing leaves, differing very much from the others, which are stalked, heart-shaped, nearly round, and evenly-toothed. All the foliage is of a rich dark shining green colour. Strong specimens produce flowers for a long time, fully two months, and frequently they burst into blossom again in the autumn. Individual flowers are very lasting, and, moreover, are very effective in a cut state. It is a robust grower, providing it is not in light dry soil; it seems with me to do equally well fully exposed to sunshine and in partial shade, but both positions are of a moist character.

Fig. 22. Calthus Palustris Flore-Pleno.

(One-half natural size.)

It has long fleshy roots, which allows of its being transplanted at any time, early spring being the best, to increase it. The crowns should be divided every three years, when there will be found to be ample roots to each one.

Flowering period, April to June.

Calystegia Pubescens Flore-pleno

Nat. Ord. Convolvulaceæ

This double Convolvulus is a somewhat recent introduction from China; it is hardy and perennial. So distinct are its large flesh-coloured flowers that they are often taken at the first glance, when cut, for double pyrethrums or chrysanthemums, but, seen in connection with the plant, the form of foliage and climbing or twining habit of the bindweed soon enable the most casual observer of flowers to recognise its genus.

The flowers are 2in. to 3in. across, petals long, narrow, wavy, and reflexed; these are well held together by the five-parted calyx, further supported by a bract of two small but stout leaves. The flower stalks are round and wiry, 3in. or 4in. long; they are produced all along the twining stems, which are only of the moderate length of 5ft. or 6ft. The leaves are of the well-known Convolvulus form.

I find it a good plan to grow this subject amongst tall and early flowering plants, such as lupins, foxgloves, and lilies, the old stems of which form ample supports for the climber; moreover, they are rendered less unsightly from being thus furnished anew with leaf and flower, even though not their own. Another method is in early summer to place a short twiggy branch over the pushing growths; it will soon become covered, and if not too large, the ends of the shoots will slightly outgrow the twigs and hang down in a pleasing manner. The plant should be started in light sandy loam and have a warm situation, otherwise flowers will be scarce and the whole specimen have a weedy appearance. When once it becomes established, it will be found to spread rapidly by means of its running roots, which, unless checked, will soon become a pest. I simply pull out all growths except such as shoot up in the desired position, and so continue to treat them as weeds throughout the growing season. Stems furnished with flowers a yard or more long, in a cut state, make rich festoons; single blooms (the smaller ones) look well as "buttonholes," being neat and effective, without gaudiness. I ought to state that a succession of flowers is kept up for fully three months; this fact adds not a little to the value of this handsome flesh-coloured bloomer. Roots may be transplanted at any time; the smallest piece will produce a blooming plant the first season, if put into a proper soil and situation.

Flowering period, July to September.

Campanula Grandis

Great Bellflower; Nat. Ord. Campanulaceæ

A hardy herbaceous perennial from Siberia, growing to a height of 3ft. Its flowers are large, bright, and numerous; well-established clumps will present masses of bloom for more than a month with average weather. As a large showy subject there are few plants more reliable, or that can in any way excel it, more especially for town gardens. It is a rampant grower, quickly covering large spaces by means of its progressive roots; in gardens or collections where it can only be allowed a limited space, the running habit of the roots will doubtless prove troublesome, and often such free growers, however handsome they may be otherwise, are esteemed common, which should not be. The proper thing to do would be to give these vigorous and fine flowering subjects such quarters as will allow them their natural and unrestrained development.

The flowers of C. grandis are more than 1in. across the corolla, the five segments being large and bluntly pointed, of a transparent purple-blue colour, and very enduring; they are arranged on short stalks, which issue from the strong upright stems. They form little tufts of bloom at every joint for a length of nearly 2ft.; the succession, too, is well kept up. Buds continue to form long after the earliest have opened. The leaves are 4in. to 8in. long and ¾in. wide, lance-shaped, stalkless, and finely toothed. They are arranged in round tufts on the unproductive crowns, and they remain green throughout the winter.

As regards soil, any kind will do; neither is the question of position of any moment beyond the precaution which should be taken against its encroachments on smaller subjects. In the partial shade of shrubs it not only flowers well but proves very effective. Useful as this plant is in the garden, it becomes far more so in a cut state. When it is needful to make up a bold vase or basket of flowers for room decoration, it can be quickly and effectively done by a liberal use of its long, leafy, but well-bloomed spikes; five or six of them, 2ft. to 3ft. long, based with a few large roses, pæonies, or sprays of thalictrum, make a noble ornament for the table, hall, or sideboard, and it is not one of the least useful flowers for trays or dishes when cut short. Propagated by division at any time, the parts may be planted at once in their blooming quarters.

Flowering period, June and July.

Campanula Latifolia

Broad-leaved Bellflower; Nat. Ord. Campanulaceæ

A British species, very much resembling C. grandis, but somewhat taller, and flowering a little earlier; the latter quality has induced me to mention it, as it offers a fine spike for cutting purposes before the above is ready.

Culture, uses, and propagation, the same as for C. grandis.

Flowering period, June and July.

Campanula Persicifolia

Peach-leaved Bellflower; Old Common Names, "Peach-bels" and "Steeple-bels"; Nat. Ord. Campanulaceæ

This good "old-fashioned" perennial has had a place in English gardens for several hundred years; it is still justly and highly esteemed. It is a well-known plant, and as the specific name is descriptive of the leaves, I will only add a few words of Gerarde's respecting the flowers: "Alongst the stalke growe many flowers like bels, sometime white, and for the most part, of a faire blewe colour; but the bels are nothing so deepe as they of the other kindes, and these also are more delated and spred abroade then any of the reste." The varieties include single blue (type) and white, double blue, and different forms of double white.

In all cases the corolla is cup or broad bell shaped, and the flowers are sparingly produced on slightly foliaged stems, 18in. to 3ft. high; there are, however, such marked distinctions belonging to C. p. alba fl.-pl. in two forms that they deserve special notice; they are very desirable flowers, on the score of both quaintness and beauty. I will first notice the kind with two corollas, the inner bell of which will be more than an inch deep, and about the same in diameter. The outer corolla is much shorter, crumpled, rolled back, and somewhat marked with green, as if intermediate in its nature between the larger corolla and the calyx. The whole flower has a droll but pleasing form, and I have heard it not inaptly called "Grandmother's Frilled Cap." The other kind has five or more corollas, which are neatly arranged, each growing less as they approach the centre. In all, the segments are but slightly divided, though neatly formed; this flower is of the purest white and very beautiful, resembling a small double rose. It is one of the best flowers to be found at its season in the borders, and for cutting purposes I know none to surpass it; it is clean and durable. So much are the flowers esteemed, that the plant is often grown in pots for forcing and conservatory decoration, to which treatment it takes kindly.

In the open all the above varieties grow freely in any kind of garden soil, but if transplanted in the autumn into newly-dug quarters they will in every way prove more satisfactory; this is not necessary, but if cultivation means anything, it means we should adopt the best-known methods of treatment towards all the plants we grow, and certainly some of the above Bellflowers are deserving of all the care that flowers are worth.

Flowering period, July to September.

Campanula Pyramidalis

Pyramidal or Chimney Campanula; Nat. Ord. Campanulaceæ

This herbaceous perennial is a very old flower in this country; it came from Carniola in the year 1594. It is very hardy, and for several months together it continues to produce its large lively blue flowers, beginning in July and lasting until stopped by frosts. At no time is it in finer form than in September; at the height of from 5ft. to 7ft. it proves richly effective amongst the blooming hollyhocks, where, as regards colour, it supplies the "missing link" (see Fig. 23).

The flowers are a light bright blue colour, and 1in. to 1½in. across. The corolla is bell-shaped, the five divisions being deeply cut, which allows the flower to expand well; the calyx is neat and smooth, the segments long and awl-shaped; the flower stalks are short, causing the numerous erect branches to be closely furnished with bloom during favourable weather. The leaves of the root are very large and stalked, of irregular shape, but for the most part broadly oval or lance-shaped. The edges are slightly toothed, having minute glands; those of the stems are much smaller, sessile, and long egg-shaped; all the foliage is smooth, and of a dark green colour; the main stems are very stout, and sometimes grow to the height of 7ft. Vigorous plants will send up several of these, from which a great number of small ones issue, all assuming an erect habit; blooming specimens are hardly anything else than a wand-like set of flowered stems, and though it is advisable to stake them, I have seen them bend and wave during high winds without damage.

Fig. 23. Campanula Pyramidalis.

(One-twentieth natural size; a, one-half natural size.)

In the borders and shrubbery this is a very effective subject; it is amongst herbaceous plants what the Lombardy poplar is amongst forest trees—tall, elegant, and distinct. Its use, however, is somewhat limited, owing to the stiffness of the stems and the shortness of the flower stalks; but when grown in pots—as it often is—for indoor decoration, it proves useful for standing amongst orange and camellia trees. It has very strong tap roots, and enjoys a deep rich loam. Not only does it look well among trees, but otherwise the partial shade of such quarters seems conducive to finer bloom.

Flowering period, July to October.

C. p. alba is a white flowering variety of the above species; its other points of distinction are its smaller-sized leaves and much paler green colour, by which alone the plants may be easily recognised from the type. This variety may be grown with good effect in pots or the border; it scarcely gets so tall as the blue form, but looks well by the side of it.

The readiest way to increase these plants is to take the young and dwarf growths from the woody crown of the roots, paring off a little of the bark with each. If these are put in sandy loam during the warm growing season and kept shaded for a few days, they will very soon make plenty of roots; this method in no way damages the flowers. Another way is by seed, but seedlings are two years before they bloom.

Campanula Speciosa

Showy Harebell; Nat. Ord. Campanulaceæ

A comparatively new species, brought from Siberia in 1825, and sometimes called C. glomerata dahurica. It is a good hardy plant, perennial and herbaceous, and one of the earliest to flower. It has a distinct appearance; it nearly resembles C. aggregata, but the latter does not flower until several weeks later. Apart from its likeness to other species of the genus, it is a first-class border flower, having large bells of a fine deep purple colour, and, unlike many of the Harebells, is not over tall, but usually about a foot high, having a neat habit. The flowers are arranged in dense heads, whorl fashion, having very short stalks; they are nearly 2in. long and bell shaped. The leaves (radical) are oval heart-shaped and stalked; those of the stems are sessile; the whole plant is hairy and robust. This is one of the flowers which can hardly be planted out of place in any garden, excepting amongst the rare and very dwarf alpines; it is not only true to its name, "showy," but handsome. It will grow and flower well in the worst soil and needs no sort of care; it would be fine in lines by a shrubbery, and is effective in bold clumps; and though a new kind, it belongs to a race of "old-fashioned" flowers, amongst which it would mix appropriately. Increased by division in autumn.

Flowering period, June and July.
