Hardy Perennials and Old Fashioned Flowers Part 41

Rudbeckia Californica.

CALIFORNIAN CONE-FLOWER; _Nat. Ord._ COMPOSITae.

This, in all its parts, is a very large and showy subject; the flowers are 3in. to 6in. across, in the style of the sunflower. It has not long been grown in English gardens, and came, as its name implies, from California: it is very suitable for a.s.sociation with old-fas.h.i.+oned flowers, being nearly related to the genus _Helianthus_, or sunflower.

It is not only perfectly hardy in this climate, which is more than can be said of very many of the Californian species, but it grows rampantly and flowers well. It is all the more valuable as a flower from the fact that it comes into bloom several weeks earlier than most of the large yellow Composites. Having stated already the size of its flower, I need scarcely add that it is one of the showiest subjects in the garden; it is, however, as well to keep it in the background, not only on account of its tallness, but also because of its coa.r.s.e abundant foliage.

It grows 4ft. to 6ft. high, the stems being many-branched. The flowers have erect stout stalks, and vary in size from 3in. to 6in. across, being of a light but glistening yellow colour; the ray is somewhat unevenly formed, owing to the florets being of various sizes, sometimes slit at the points, lobed, notched, and bent; the disk is very bold, being nearly 2in. high, in the form of a cone, whence the name "cone flower." The fertile florets of the disk or cone are green, and produce an abundance of yellow pollen, but it is gradually developed, and forms a yellow ring round the dark green cone, which rises slowly to the top when the florets of the ray fall; from this it will be seen that the flowers last a long time. The leaves of the root are sometimes a foot in length and half as broad, being oval, pointed, and sometimes notched or lobed; also rough, from a covering of short stiff hairs, and having once-grooved stout stalks 9in. or more long; the leaves of the stems are much smaller, generally oval, but of very uneven form, bluntly pointed, distinctly toothed, and some of the teeth so large as to be more appropriately described as segments; the base abruptly narrows into a very short stalk. The flowers of this plant are sure to meet with much favour, especially while the present fas.h.i.+on continues; but apart from fas.h.i.+on, merely considered as a decorative subject for the garden, it is well worth a place. There are larger yellow Composites, but either they are much later, or they are not perennial species, and otherwise this one differs materially from them.

I need not say anything respecting this form of flower in a cut state--its effectiveness is well known. If planted in ordinary garden loam it will hold its place and bloom freely year after year without further care. Smaller subjects should not be set too near it; it may be unadvisable to plant too many clumps in the same garden, but it can be allowed to spread into one bold patch. The best time to divide or transplant is in early spring, when growth is just pus.h.i.+ng, for vigorous as this and many other perennials are, I have often found them to rot, when the dormant roots, after being cut into pieces, have had to face the winter.

Flowering period, July to September.

Rudbeckia Serotina.

_Late_ CONE-FLOWER; _Nat. Ord._ COMPOSITae.

This hardy American species, though not an old plant in English gardens, is nevertheless cla.s.sed with "old-fas.h.i.+oned" plants and flowers; and certainly its sombre but pleasing dark golden ray flowers, together with its likeness to many of the old sunflowers, favours such cla.s.sification.

It is the latest of a late-flowering genus.

It attains the height of 2ft.; the root leaves are of irregular shape, some oval and pointed, others, on the same plant, being lance-shaped, with two or three large teeth or acute lobes; in size the leaves also vary from 3in. to 8in. long, and being covered with short bristly hairs, they are very rough, also of a dull green colour; the flower stems have but few leaves, so it will be judged that the plant has but a weedy appearance, but this is compensated for by the rich and numerous large dark orange flowers, 3in. across; the ray is single, and the centre, which is large and prominent, is a rich chocolate brown.

This subject, to be effective, should be grown in large specimens; mine is about 3ft. in diameter, and the level ma.s.s of flowers, as I have often noticed them in twilight, were grandly beautiful. I can well understand that many have not cared for this cone flower when they have judged it from a small plant which has sent up its first, and perhaps abnormal, bloom. It is especially a subject that should be seen in bold clumps, and in moderately rich soil it will soon become such. Moreover, the flowers are very effective in a cut state, when loosely arranged in vases, only needing something in the way of tall gra.s.ses to blend with in order to form an antique "posy."

Autumn is the best time to plant it; its long roots denote that it enjoys deep soil, and, when planted, the roots of this, as well as all others then being transplanted, should be made firm, otherwise the frost will lift them out and the droughts will finish them off. Many plants are lost in this manner, and, indeed, many short-rooted kinds are scarcely saved by the greatest care. The stem-rooting character of this plant affords ready means of propagation by root divisions.

Flowering period, from September till strong frosts.

Salix Reticulata.

WRINKLED _or_ NETTED WILLOW; _Nat. Ord._ SALICACEae.

A native deciduous shrub, of creeping or prostrate habit, not growing higher than 2in. As the flowers are inconspicuous and only interesting to the botanist or when under the microscope, let me at once say I mention this subject because of its beautiful habit and distinct quality of foliage. When grown on rockwork, no other plant can compare with it, and where choice spring bulbs are planted, this handsome creeper may be allowed, without injury to such roots, to broadly establish itself; so grown, its little stout leaves, thickly produced, flatly on the surface, are much admired.

The flowers or catkins stand well above the foliage, but are unattractive, being of a dusky brown colour; the leaves are dark green, downy, of much substance, 1in. long, and nearly 1in. broad, but the size of foliage varies according to the conditions under which the specimens are grown; the sizes now referred to are of plants grown on rather dry rockwork and fully exposed; the form of the leaves is...o...b..cular, obtuse, not in the least notched, bald, reticulately veined, and glaucous beneath; the stems are short and diffuse, and tinged with red on the younger parts.

During winter, when bare of foliage, its thick creeping stems, covered with fat buds and interlaced in a pleasing manner, render it interesting in almost any situation not shaded. It forms a capital carpet plant from early spring to the end of summer.

It is in no way particular as regards soil, and though it loves moisture, like most other willows, it proves thriving in dry places. It is, moreover, a good grower in large towns. Its propagation may be carried out before the leaves unfold in spring. Little branches with roots to them may be cut from the parent plant, and should be set in sandy loam and watered well to settle it about the roots.

Flowering period, September to strong frosts.

Sanguinaria Canadensis.

BLOODROOT; _Nat. Ord._ PAPAVERACEae.

This is a native of North America, and is, therefore, hardy in this climate; tuberous rooted. It is a curious plant, not only from its great fulness of sap or juice, which is red (that of the root being darker, whence its name Bloodroot), but also because of the shape of its leaves, their colour, and method of development (see Fig. 81). Though very dwarf, it is handsome and distinct.

The flowers are pure white and nearly 2in. across; the petals have good substance, but they fall in five or six sunny days; the stamens are numerous and bright yellow. Though belonging to the order of the Poppy, it is in many respects unlike it; each flower stem, which is 6in. high, springs directly from the root, and only one flower is produced on a stem; the leaves are also radical, so that the plant is branchless and stemless; the leaf stalks are rather shorter than those of the flowers.

The foliage is of a slate-grey colour, prominently veined on the under side, the upper surface being somewhat wrinkled; the leaves are 3in.

across when fully developed, vine-leaf shaped, deeply and beautifully lobed; their development is slow, not being completed until the bloom is past. Both leaves and flowers are produced in a curious fas.h.i.+on; for a time the flower-bud is compactly enfolded by a leaf, and so both grow up to the height of 2in. or 3in., when the former pushes through, and soon swells its olive-shaped buds. At this stage a good specimen clump is very attractive, and is only more so when the fine blooms first open.

[Ill.u.s.tration: FIG. 81. SANGUINARIA CANADENSIS.

(One-half natural size.)]

It should be grown amongst some such carpeting plants as _Sibthorpia Europaea_ or _Linaria pilosa_, so as to protect it; moreover, these creepers are suited for a similar soil and position. The soil should be light, either of sandy or vegetable character, but one that cannot bake; shade from the mid-day sun is essential, as also is plenty of moisture.

When the growths have become crowded, as they do in about three years, it is as well to lift, divide, and replant at a distance of 3in.; this is best done after the tops have died off in summer; plant 4in. or 5in.

deep.

Flowering period, April and May.

Saponaria Ocymoides.

ROCK SOAPWORT, _or_ BASIL-LEAVED SOAPWORT: _Nat. Ord._ SILENACEae.

A very hardy alpine from France, and one of the most floriferous subjects that can be placed on rockwork, where should be its position.

During a single season it is no uncommon thing to see a small plant grow into a large cus.h.i.+on 2ft. in diameter, and only 6in. or 9in. high. In planting it this fact should not be overlooked, not only for the sake of giving it plenty of room, but also in order that less vigorous subjects near it may not become overgrown; it blooms all summer, and though the flowers are small and not at all bright, their numbers render it attractive.

The flowers, which are about in. across, are of a pink colour, and produced on many-branched prostrate stems; the calyx is five-toothed; the corolla is formed of five flat petals; the leaves are small, basil-like, oval-lance shaped, entire and smooth; the general appearance of the plant when in bloom is that of a compact ma.s.s of small leaves and flowers, the latter predominating.

It will grow in any kind of soil, but prefers that of a vegetable character, with its roots amongst large stones; but, strictly speaking, it needs nothing but an open situation and plenty of room to spread. It ripens an abundance of seed, and there is not a better mode of propagation than its own; hundreds of stout seedlings appear the following spring around the parent plant, and these may then be transplanted, and they will flower the same season.

_S. o. splendens_ is a variety of the above very much improved indeed; and though one cannot discard the good old plant for its very recent offspring, the former is certainly very much eclipsed. _Splendens_ has foliage slightly different, but its flowers are much larger and brighter; and though it may not be quite so vigorous, in this case that may be considered an improvement. It is said to come true from seed.

Flowering period, May to August.

Saxifraga Burseriana.
