Hardy Perennials and Old Fashioned Flowers Part 34

This is indeed a well-named species or variety, whichever it may be; little seems to be known of its origin, but that it is distinct and beautiful is beyond doubt. It s.h.i.+nes most as a rock plant; its long and bending stems, which are somewhat proc.u.mbent, have as much rigidity about them as to prevent their having a weak appearance; the tips, moreover, are erect, showing off to advantage the handsome imbricate bracts, bespangled as they are with numerous rosy-purple blossoms. The long and elegant panicles of bracteae, together with the pleasing arrangement thereof, are the main features of this subject.

The rosy flowers are very small, and have the appearance of being packed between the bracteoles; still, their gaping forms are distinctly traceable, but the pretty lipped calyxes are quite hidden; the bract leaves are roundly-oval, acute, cupped, and touched with a nutty-brown tint on the outer sides; the spikes have many minor ones, being as fine as a thread, covered with short soft hairs, and of a brown colour; the leaves are in. long, oval, entire, and downy. The plant or shrub grows 18in. high. As already hinted, the habit is proc.u.mbent, the older flower stems being woody; not only is it a bright object for rockwork, but it is in its finest form when most other flowers are past. The branches are useful in a cut state; the slender spikelets, with their pale green and brown tinted bracts, are very pretty by gas light, and they keep well for a long time in water.

The Marjorams are fond of a dry situation, and this is no exception to that rule. Rockwork or raised beds of sandy loam suits it to perfection, provided the aspect is sunny. It will, therefore, be seen that there is nothing special about its culture, neither is there in its propagation; cuttings may be taken in summer, or the rooted shoots may be divided at almost any time.

It flowers from September to the time of severe frosts, and is in its greatest beauty in October.

Orobus Vernus.

PEASELING, OR SPRING BITTER VETCH; _Nat. Ord._ LEGUMINOSae.

A hardy herbaceous perennial; it flowers in very early spring, and sometimes sooner, but it is in full beauty in April, its blooming period being very prolonged. Not only is this bright and handsome pea flower worth attention being a very old subject of English gardens, but also because of its intrinsic merit as a decorative plant. I say plant designedly, as its form is both sprightly and elegant, which, I fear, the ill.u.s.tration (Fig. 70) can hardly do justice to--more especially its spring tints and colours.

[Ill.u.s.tration: FIG. 70. OROBUS VERNUS.

(One-fourth, natural size.)]

Pretty nearly as soon as the growths are out of the earth the flowers begin to appear. The greatest height the plants attain rarely exceeds a foot; this commends it as a suitable border plant. Individually the flowers are not showy, but collectively they are pleasing and effective.

When they first open they are a mixture of green, red, blue, and purple, the latter predominating. As they become older they merge into blue, so that a plant shows many flowers in various shades, none of which are quite an inch long, and being borne on slender drooping stalks, which issue from the leafy stems, somewhat below the leading growths, the bloom is set off to great advantage. The foliage in form resembles the common vetch, but is rather larger in the leaflets, and instead of being downy like the vetch, the leaves are smooth and bright. In a cut state, sprays are very useful, giving lightness to the stiffer spring flowers, such as tulips, narcissi, and hyacinths. Rockwork suits it admirably; it also does well in borders; but in any position it pays for liberal treatment in the form of heavy manuring. It seeds freely, and may be propagated by the seed or division of strong roots in the autumn.

Whether rabbits can scent it a considerable distance off, I cannot say, but, certain it is, they find mine every year, and in one part of the garden eat it off bare.

Flowering period, March to May.

Ourisia Coccinea.

_Nat. Ord._ SCROPHULARIACEae.

A hardy herbaceous perennial from South America, as yet rarely seen in English gardens, and more seldom in good form. As may be judged by the ill.u.s.tration (Fig. 71), it is a charming plant, but it has beauties which cannot be there depicted; its deep green and s.h.i.+ning leaves const.i.tute wavy ma.s.ses of foliage, most pleasing to see, and the short-stemmed, lax cl.u.s.ters of dazzling scarlet flowers are thereby set off to great advantage. I have no fear of overpraising this plant, as one cannot well do that. I will, however, add that it is a decorative subject of the highest order, without a single coa.r.s.e feature about it; seldom is it seen without a few solitary sprays of flowers, and it is never met with in a seedy or flabby state of foliage, but it remains plump throughout the autumn, when it sometimes shows a disposition to indulge in "autumnal tints." Though seldom encountered, this lovely plant is well known, as it is pretty sure to be, from notes made of it and published with other garden news; but it has the reputation of being a fickle plant, difficult to grow, and a shy bloomer. I trust this statement will not deter a single reader from introducing it into his garden; if I had found it manageable only with an unreasonable amount of care, I would not have introduced it here. It certainly requires special treatment, but all the conditions are so simple and practicable, in even the smallest garden, that it cannot be fairly termed difficult, as we shall shortly see.

The flowers are 1in. long, in form intermediate between the pentstemon and snapdragon, but in size smaller, and the colour an unmixed deep scarlet: they are produced on stems 9in. high, round, hairy, and furnished with a pair of very small stem-clasping leaves, and where the panicle of flowers begins there is a small bract, and less perfectly developed ones are at every joint, whence spring the wiry flower stalks in fours, threes, and twos, of various lengths and a ruddy colour. The panicles are lax and bending; the flowers, too, are pendent; calyx, five-parted and sharply toothed; stamens, four, and long as petals; anthers, large and cream coloured, style long and protruding. The leaves are radical, and have long, hairy, bending stalks; the main ribs are also hairy; beneath, they are of a deep green colour, bald, s.h.i.+ning, veined and wrinkled; their form is somewhat heart-shaped, sometimes oval, lobed, but not deeply, and unevenly notched; they grow in dense ma.s.ses to the height of 6in.

[Ill.u.s.tration: FIG. 71. OURISIA COCCINEA.

(Plant, one-fourth natural size; 1, blossom, one-half natural size.)]

It is said to like a peaty soil, in which I have never tried it. In the management of this plant I have found position to be the main desideratum; the soil may be almost anything if it is kept moist and sweet by good drainage, but _Ourisia coccinea_ will not endure exposure to hot suns.h.i.+ne; even if the soil is moist it will suffer. I have large patches of it, 3ft. in diameter, growing in a mixture of clay and ashes, formed into a bank 18in. high, sloping north and screened by a hedge nearly 6ft. high from the mid-day sun, and shaded by overhanging trees; and I may also add that during the three years my specimens have occupied this shady, moist, but well drained position they have grown and flowered freely, always best in the deepest shade. As before hinted, there is a sort of special treatment required by this plant, but it is, after all, very simple. It is a slow surface creeper, should be planted freely in frequented parts of the garden, if the needful conditions exist, and no more beautiful surfacing can be recommended; grown in such quant.i.ties it will be available for cutting purposes. As a cut flower it is remarkably distinct and fine; it so outs.h.i.+nes most other flowers that it must either have well selected company or be used with only a few ferns or gra.s.ses.

It is readily increased by division of the creeping roots, which is best done in early spring. If such divisions are made in the autumn, according to my experience, the roots rot; they should therefore be taken off either in summer, when there is still time for the young stock to make roots, or be left in the parent clump until spring, when they will start into growth at once.

Flowering period, May to September.

Papaver Orientale.

ORIENTAL POPPY; _Nat. Ord._ PAPAVERACEae.

The Oriental Poppy is a bold and showy plant, very hardy and perennial.

There are several colours, but the bright scarlet variety is the most effective. Specimens of it which have become well established have a brilliant appearance during June; they are 3ft. high and attract the eye from a distance. Among other large herbaceous plants, as lupines, paeonies, thalictrums, &c., or even mixed with dwarf shrubs, they are grandly effective; indeed, almost too much so, as by the size and deep colour of the flowers they dazzle the eye and throw into the shade the surrounding flowers of greater beauty. The kinds with brick-red and other shades are comparatively useless. Their flowers are not only smaller, but wind or a few drops of rain spot the petals. A night's dew has the same effect; the stems, too, are weak and bending, which makes them much wanting in boldness, and when the flowers are damaged and the stems down there is little left about the Oriental Poppies that is ornamental.

[Ill.u.s.tration: FIG. 72. PAPAVER ORIENTALE (_var._ BRACTEATUM).

(One-fourth natural size.)]

The flowers are 6in. to 8in. across when expanded, produced singly on stout round stems covered with stiff hairs flattened down, and also distantly furnished with small pinnate leaves. Only in some varieties is the leafy bract (Fig. 72) to be found. This variety is sometimes called _P. bracteatum_. The calyx is three-parted and very rough; the six petals (see engraving) are large, having well defined dark spots, about the size of a penny piece. The leaves are a foot or more in length, stiff but bending; they are thickly furnished with short hairs, pinnate and serrated.

This large poppy can be grown to an enormous size, and otherwise vastly improved by generous treatment; in a newly trenched and well manured plot a specimen has grown 3ft. high, and produced flowers 9in. across, the colour being fine; it will, however, do well in less favoured quarters--in fact, it may be used to fill up any odd vacancies in the shrubbery or borders. It is readily increased by division of the roots, and this may be done any time from autumn to February; it also ripens seed freely.

Flowering period, May to June.

Pentstemons.

_Nat. Ord._ SCROPHULARIACEae.

The hybrids, which const.i.tute the numerous and beautiful cla.s.s commonly grown as "florists' flowers," are the kinds now under notice. The plant, when a year old, has a half-shrubby appearance, and if I said that it was but half hardy I should probably be nearer the mark than if I p.r.o.nounced it quite hardy. It may, therefore, appear odd that I should cla.s.s it with hardy perennials; there are, however, good reasons for doing so, and as these extra fine border plants are great favourites and deserve all the care that flowers can be worth, I will indicate my mode of growing them; but first I will state why the hybrid Pentstemons are here cla.s.sed as hardy. One reason is that some varieties really are so, but most are not, and more especially has that proved to be the case during recent severe winters--the old plants, which I never trouble to take in, are mostly killed. Another reason why I do not object to their being cla.s.sed as hardy is that cuttings or shoots from the roots appear to winter outside, if taken in the summer or autumn and dibbled into sand or a raised bed (so that it be somewhat drier than beds of the ordinary level), where they will readily root. Such a bed of cuttings I have found to keep green all the winter, without any protection other than a little dry bracken. My plants are so propagated and wintered.

The Pentstemon has of late years been much improved by hybridising, so that now the flowers, which resemble foxgloves, are not only larger than those of the typical forms, but also brighter, and few subjects in our gardens can vie with them for effectiveness; moreover, they are produced for several months together on the same plants, and always have a remarkably fresh appearance.

The corolla, which can be well seen both inside and out, has the pleasing feature of clearly p.r.o.nounced colour on the outside, and rich and harmonious shadings inside; such flowers, loosely arranged on stems about 2ft. high, more or less branched, and furnished with lance-shaped foliage of a bright glossy green, go to make this border plant one that is justly esteemed, and which certainly deserves the little extra care needful during winter.

[Ill.u.s.tration: FIG. 73. PENTSTEMON.

(One-fourth natural size.)]

It is grandly effective in rows, but if in a fully exposed position it flags during hot suns.h.i.+ne; it is, therefore, a suitable plant to put among shrubs, the cool shelter of which it seems to enjoy. The remarks I have already made respecting its hardiness sufficiently indicate the mode of propagation. Old plants should not be depended upon, for though they are thoroughly perennial, they are not so hardy as the younger and less woody stuff--besides, young plants are far more vigorous bloomers.

Flowering period, June to August.

Petasites Vulgaris.
