Hardy Perennials and Old Fashioned Flowers

Phlox Frondosa

Fronded P.; Nat. Ord. Polemoniaceæ

A hardy creeper; one of the dwarf section, having half-woody, wiry stems. For this and many other species of the Creeping Phlox we are indebted to North America. Of late years these beautiful flowers have received much attention, not only from the trade, but also from amateurs, some of whom have taken much pains in crossing the species by hybridising, notably the late Rev. J. G. Nelson. Perhaps the most distinct and beautiful of all the dwarf Phloxes is the one which bears his name—the white-flowered P. Nelsoni. I have selected the species P. frondosa, because the specific name is, perhaps, beyond that of any of the others, more generally descriptive of all the following kinds: P. divaricata, P. glaberrima, P. Nelsoni (white flowers), P. reflexa, P. oculata, P. setacea, P. s. atropurpurea, P. s. violacæa, P. subulata, P. prostrata. These differ but slightly from one another, so little, indeed, that many discard the distinctions; still, they do exist, and may be clearly seen when grown close together in collections. The flowers differ in depth of colour; the leaves of some are more recurved, crossed, twisted, shining, or pointed, also broader and longer; the stems likewise differ; herein the distinctions are seen, probably, more than in either flowers or leaves. Sometimes they are, in the different species, long or short, leafy, branched, dense, arched, and divaricate, but, although at any time when their fresh foliage is upon them, and when they are so close together that the eye can take them all in at a glance, their distinctions are fairly clear, autumn is the time to see them in their most definite and beautiful form. Like many other North American plants, they have lovely autumnal tints, then their forms have rich glistening colours, and they are seen to not only differ considerably, but, perhaps, to more advantage than when in flower; but let me add at once that I have only proved these plants to take such rich autumnal colours when they have been grown so as to rest on stones, which not only keep them from excess of moisture, from worm casts, &c., but secure for them a healthy circulation of air under their dense foliage. From the above, then, it will be seen that a general description of P. frondosa will apply to the other species and varieties mentioned.

The flowers are lilac-rose; calyx, tubular; corolla of five petals, narrow and notched; leaves, awl-shaped, short, bent, and opposite; stems, branched, dense and trailing.

The dwarf Phloxes are pre-eminently rock plants, as which they thrive well; when raised from the ground level, so as to be nearly in the line of sight, they are very effective. They should be so planted that they can fall over the stones, like the one from which the illustration (Fig. 74) was drawn. For at least a fortnight the plants are literally covered with flowers, and at all times they form neat rock plants, though in winter they have the appearance of short withered grass; even then the stems are full of health, and in early spring they become quickly furnished with leaves and flowers. These Phloxes make good edgings. Notwithstanding their dead appearance in winter, a capital suggestion occurred to me by an accidental mixture of croci with the Phlox. At the time when the latter is most unseasonable the crocuses, which should be planted in the same line, may be seen coming through the browned foliage. When in flower, the blooms will not only be supported by this means, but also be preserved from splashes; when the crocuses are past their prime, the Phlox will have begun to grow, and, to further its well doing, its stems should be lifted and the then lengthened foliage of the crocuses should be drawn back to the under side of the Phlox, where it might remain to die off. This would allow the Phlox to have the full light, and the arrangement would be suitable for the edge of a shrubbery or border of herbaceous plants, or even along the walks of a kitchen garden.

The Phloxes are easily propagated, either from rooted layers or cuttings. The latter should be put into a good loam and kept shaded for a week or two. Early spring is the best time.

Flowering period, March to May.

Physalis Alkekengi

Winter Cherry; Nat. Ord. Solanaceæ

This plant begins to flower in summer; but as a garden subject its blossom is of no value; the fine large berries, however, which are suspended in orange-yellow husks of large size, are very ornamental indeed, and form a very pleasing object amongst other "autumnal tints." It is not till October that the fruit begins to show its richness of colour. The plant is quite hardy, though a native of southern Europe; it is also herbaceous and perennial, and it has been grown in this country for 330 years. Still, it is not to be seen in many gardens. An old common name for it was "Red Nightshade," and Gerarde gives a capital illustration of it in his Herbal, under the name Solanum Halicacabum.

P. Alkekengi grows to the height of about two feet. The stems of the plant are very curious, being somewhat zigzag in shape, swollen at the nodes, with sharp ridges all along the stems; otherwise, they are round and smooth. The leaves are produced in twins, their long stalks issuing from the same part of the joint; they are of various forms and sizes, but mostly heart-shaped, somewhat acute, and 2in. to 4in. long. The little soft creamy white flowers spring from the junction of the twin leaf-stalks; their anthers are bulky for so small a flower. The calyx continues to grow after the flower has faded, and forms the Chinese-lantern-like covering of the scarlet berry; the latter will be over ½in. in diameter, and the orange-coloured calyx 1½in., when fully developed. In autumn the older stems cast their leaves early, when the finely-coloured fruit shows to advantage; the younger stems keep green longer, and continue to flower until stopped by the frost. To this short description I may add that of Gerarde, which is not only clear but pleasantly novel: "The red winter Cherrie bringeth foorth stalkes a cubite long, rounde, slender, smooth, and somewhat reddish, reeling this way and that way by reason of his weakness, not able to stande vpright without a support: whereupon do growe leaues not vnlike to those of common nightshade, but greater; among which leaues come foorth white flowers, consisting of five small leaues; in the middle of which leaues standeth out a berrie, greene at the first, and red when it is ripe, in colour of our common Cherrie and of the same bignesse, which is enclosed in a thinne huske or little bladder of a pale reddish colour, in which berrie is conteined many small flat seedes of a pale colour. The rootes be long, not vnlike to the rootes of Couch grasse, ramping and creeping within the vpper crust of the earth farre abroade, whereby it encreaseth greatly."

The stems, furnished with fruit of good colour, but otherwise bare, make capital decorations for indoors, when mixed with tall grasses, either fresh or dried, and for such purposes this plant is worth growing; any kind of soil will do, in an out-of-the-way part, but if in shade, the rich colour will be wanting.

Flowering period, June to frosts.

Podophyllum Peltatum

Duck's-foot, sometimes called May Apple; Nat. Ord. Podophyllaceæ

Fig. 75. Podophyllum Peltatum.

(One-third natural size.)

A hardy herbaceous perennial from North America, more or less grown in English gardens since 1664. As may be seen from the illustration (Fig. 75), it is an ornamental plant, and though its flowers are interesting, they are neither showy nor conspicuous, as, from the peculiar manner in which they are produced, they are all but invisible until sought out. Its leaves and berries constitute the more ornamental parts of the plant.

The flowers are white, not unlike the small white dog-rose in both size and form; the calyx is of three leaves, which fall off; the corolla, of six to nine petals; peduncle nearly an inch long, which joins the stem at the junction of the two leaf stalks, only one flower being produced on a stem or plant. The leaves join the rather tall and naked stem by stalks, 2in. to 3in. long; they are handsome in both form and habit. As the specific name implies, the leaves are peltate or umbrella-shaped, deeply lobed, each lobe being deeply cut, and all unevenly toothed and hairy at the edges, with a fine down covering the under sides; the upper surface is of a lively, shining green colour, and finely veined. The flower is succeeded by a large one-celled ovate berry, in size and form something like a damson, but the colour is yellow when ripe, at which stage the berry becomes more conspicuous than the flower could be, from the manner in which the young leaves were held.

We want cheerful-looking plants for the bare parts under trees, and this is a suitable one, provided the surface soil has a good proportion of vegetable matter amongst it, and is rather moist. The thick horizontal roots creep near the surface, so it will be seen how important it is to secure them against drought otherwise than by depth of covering; a moist and shady position, then, is indispensable. In company with trilliums, hellebores, anemones, and ferns, this graceful plant would beautifully associate. Another way to grow it is in pots, when exactly the required kind of compost can easily be given, viz., peat and chopped sphagnum. Thus potted, plunged in wet sand, and placed in a northern aspect, it will be found not only to thrive well, as several specimens have done with me, but also to be worth all the trouble. To propagate it, the long creeping roots should be cut in lengths of several inches, and to a good bud or crown. When so cut in the autumn, I have proved them to rot when planted, but others buried in sand until February, and then planted, have done well.

Flowering period, May and June.

Polyanthus

Nat. Ord. Primulaceæ

This, with its numerous varieties, comes under Primula veris, or the common Cowslip. The improved varieties which have sprung from this native beauty of our meadows and hedgerows are innumerable, and include the rich "gold-laced" kinds—which are cared for like children and are annually placed on the exhibition tables—as well as the homely kinds, which grow in the open borders by the hundred. The Polyanthus is eminently a flower for English gardens; and this country is noted for the fine sorts here raised, our humid climate suiting the plant in every way; its flowers offer a variety of colour, an odour of the sweetest kind, full and rich, reminding us not only of spring time, but of youthful rambles and holidays.

As an "old-fashioned" flower for garden decoration it is effective and useful, from the great quantity of bloom it sends forth and the length of its flowering season; from its love of partial shade it may be planted almost anywhere. Its neat habit, too, fits it for scores of positions in which we should scarcely think of introducing less modest kinds; such nooks and corners of our gardens should be made to beam with these and kindred flowers, of which we never have too many. Plant them amongst bulbs, whose leaves die off early, and whose flowers will look all the happier for their company in spring; plant them under all sorts of trees, amongst the fruit bushes, and where only weeds have appeared, perhaps, for years; dig and plant the Polyanthus, and make the wilderness like Eden.

Flowering period, February to June.

Polygonum Brunonis

Knotweed; Nat. Ord. Polygonaceæ

This is a dwarf species from India, but quite hardy. It is pretty, interesting, and useful. The flowers are produced on erect stems a foot high, and formed in spikes 3in. to 5in. long, which are as soft as down and smell like heather. The colour is a soft rose. These flowers spring from a dense mass of rich foliage; the leaves in summer and early autumn are of a pleasing apple-green colour, smooth, oblong, and nearly spoon-shaped from the narrowing of the lower part; the midrib is prominent and nearly white; the leaf has rolled edges, and is somewhat reflexed at the point. Let the reader closely examine the leaves of this species while in their green state, holding them up to a strong light, and he will then behold the beauty and finish of Nature to a more than ordinary degree. This subject is one having the finest and most lasting of "autumnal tints," the dense bed of leaves turn to a rich brick-red, and, being persistent, they form a winter ornament in the border or on rockwork. The habit of the plant is creeping, rooting as it goes. It is a rampant grower, and sure to kill any dwarf subject that may be in its way.

It may be grown in any kind of soil, and almost in any position, but it loves sunshine. If its fine lambtail-shaped flowers are desired, it should be grown on the flat, but, for its grand red autumnal leaf tints, it should be on the upper parts of rockwork. It is self-propagating, as already hinted.

The flowers prove capital for dressing epergnes. I had not seen them so used, until the other day a lady visitor fancied a few spikes, and when I called at her house a day or two later saw them mixed with white flowers and late flowering forget-me-nots—they were charming.

Flowering period, August to the time of frosts.

Polygonum Cuspidatum

Cuspid Knotweed; Nat. Ord. Polygonaceæ

A recent introduction from China, perfectly hardy, shrub-like but herbaceous; a rampant grower, attaining the height of 6ft. or 7ft., and spreading fast by means of root suckers. During the early spring it pushes its fleshy shoots, and the coloured leaves, which are nearly red, are very pleasing; as they unfold they are seen to be richly veined, and are as handsome as the beautiful Fittonias, so much admired as hothouse plants.

The long slender stems grow apace, and when the growth has been completed the flowers issue from the axils of the leaves; they are in the form of drooping feathery panicles, 4in. to 5in. long, creamy white, and produced in clusters, lasting for three weeks or more in good condition. The leaves are 3in. to 4in. long, nearly heart-shaped but pointed, entire, and stalked, of good substance, and a pale green colour; they are alternately and beautifully arranged along the gracefully-arching stems. The specimens are attractive even when not in bloom. If the roots are allowed to run in their own way for two or three years they form a charming thicket, which must prove a pleasant feature in any large garden.

All through the summer its branches are used as dressings for large vases, and, either alone or with bold flowers, they prove most useful. In the shrubbery, where it can bend over the grass, from its distinct colour and graceful habit, it proves not only an effective but a convenient subject, as it allows the mowing machine to work without hindrance or damage. It is a capital plant for the small town garden. After sending to a friend several hampers of plants season after season, all without satisfactory results, owing to the exceptionally bad atmosphere of the neighbourhood, I sent him some of this, and it has proved suitable in every way.

Flowering period, July and August.

P. c. compactum is a variety of the above. It is, however, very distinct in the way implied by its name, being more compact and rigid, and not more than half as tall. The leaves, too, are somewhat crimped, and of a much darker colour, the stems are nearly straight and ruddy, and the flowers are in more erect racemes, the colour yellowish-white. It forms a handsome bush, but is without the graceful habit of the type. Like the other knotweeds described, it enjoys a sandy loam, and requires nothing in the way of special culture. The roots may be transplanted or divided when the tops have withered.

Polygonum Filiformis Variegatum

Knotweed; Nat. Ord. Polygonaceæ

Very hardy and effective. I simply mention this as a foliage plant. The leaves are large, drooping, and finely splashed or marbled with pale green and yellow, in shape oval-oblong, being crimped between the veins. It is a scarce variety. Fine for the sub-tropical garden. Culture, the same as for all the Knotweeds.

Flowering period, late summer.

Polygonum Vaccinifolium

Vaccinium-leaved Knotweed; Nat. Ord. Polygonaceæ

It may seem odd that we should go into the Dock family for plants and flowers for our gardens; still we may, and find some truly beautiful species. The above-named is a charming alpine, coming from the Himalayas, and proves perfectly hardy in our climate; it is seldom met with and cannot be generally known, otherwise it would be more patronised; it forms a pretty dwarf shrub, with woody slender stems, clothed with small shining foliage.

The flowers are very small, resembling those of the smaller ericas, and of a fine rosy colour; the unopened ones are even more pretty, having a coral-like effect; they are arranged in neat spikes, about 2in. long, and tapering to a fine point; they are numerously produced all along the procumbent branches, becoming erect therefrom. As the specific name denotes, the leaves are Vaccinium-like—i.e., small and oval, like box, but not so stout; they are closely set on the stems, are of a pale shining green, and somewhat bent or rolled. The habit is exceedingly neat, and, when in flower, a good specimen is a pleasing object; it is only a few inches high, but spreads quickly.

On rockwork it seems quite at home. My example has shade from the mid-day sun, and, without saying that it should have shade, I may safely say that it does well with it. The plant will thrive in sandy loam and is readily increased by putting small stones on the trailing stems, which soon root.

The leafy stems, with their coral-like, miniature spires, are useful in a cut state, so pretty, in fact, that it does not require any skill to "bring them in."

Flowering period, August to the frosts.

Potentilla Fruticosa

Shrubby Cinquefoil; Nat. Ord. Rosaceæ

In mountainous woods this native deciduous shrub is found wild, and it is much grown in gardens, where it not only proves very attractive, but from its dwarf habit and flowering throughout the summer and autumn months, it helps to keep the borders or rock garden cheerful.

The flowers, which are lemon yellow, are in form like those of its relative, the strawberry, but smaller; they are produced in terminal small bunches, but seldom are more than two or three open at the same time, and more often only one; but from the numerous branchlets, all of which produce bloom, there seems to be no lack of colour. In gardens it grows somewhat taller than in its wild state, and if well exposed to the sun it is more floriferous, and the individual flowers larger.

It attains the height of 2ft. 6in.; the flowers are 1in. across; the petals apart; calyx and bracteæ united; ten parted; each flower has a short and slender stalk. The leaves are 2in. or more in length, pinnate, five but oftener seven parted, the leaflets being oblong, pointed, entire and downy; the leaf stalks are very slender, and hardly an inch long; they spring from the woody stems or branches, which are of a ruddy colour, and also downy. The habit of the shrub is densely bushy, and the foliage has a greyish green colour from its downiness.

This subject may be planted in any part of the garden where a constant blooming and cheerful yellow flower is required; it is pretty but not showy; its best quality, perhaps, is its neatness. It enjoys a vegetable soil well drained, and propagates itself by its creeping roots, which push up shoots or suckers at short spaces from the parent stock.

Flowering period, summer to early frosts.

Pratia Repens

Syn. Lobelia Pratiana; Creeping Pratia; sometimes called Lobelia Repens; Nat. Ord. Lobeliaceæ

In October this small creeper is a very pretty object on rockwork, when the earlier bloom has become changed into oval fruit-pods. These berry-like capsules are large for so small a plant, and of a bright and pleasing colour. These, together with the few flowers that linger, backed up, as they are, with a dense bed of foliage, interlaced with its numerous filiform stems, present this subject in its most interesting and, perhaps, its prettiest form.

The flowers may be called white, but they have a violet tint, and are over half-an-inch in length. The calyx is adnate in relation to the ovarium, limb very short, but free and five-toothed; the corolla is funnel-shaped, but split at the back, causing it to appear one-sided. The solitary flowers are produced on rather long stems from the axils of the leaves. As they fade the calyces become fleshy and much enlarged, and resemble the fruit of the hawthorn when ripe. The leaves are distantly arranged on the creeping stems, ½in. long, oval, roundly toothed and undulated, fleshy, somewhat glaucous and petiolate. The habit of the plant is to root as it creeps, and the thread-like stems intersect each other in a pleasing way. They are to be seen distinctly, as the leaves are not only small, but distant, and seem to rest on a lattice-work of stems. This species comes from the Falkland Islands, and is of recent introduction.

It is herbaceous and perennial, and proves hardy in this climate if planted on a well-drained soil of a vegetable character. It not only enjoys such a position as the slope of rockwork, but, when so placed, it may be seen to advantage. It should be free from shade, or the fruit will not colour well. It will therefore be seen that this is a rock plant, so far as its decorative qualities are concerned. It may, however, be grown well on flat beds of peat soil, where its fruit will mature finely, but it cannot be so well seen. It is self-propagating. Transplantings should be made in spring, or tufts may be placed in pots, during the autumn, and put in cold frames, as then they would not suffer displacement by frosts.

Flowering period, June to frosts.
