Hardy Perennials and Old Fashioned Flowers Describing the Most Desirable Plants, for Borders, Rockeries, and Shrubberies. — Themes and Context

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_.

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.

Cultivation and flowering period, as given under _Heuchera_.

_Nat. Ord._ SAXIFRAGACEÆ.

This was presented to me in 1881 by a lady, who informed me that it was introduced by the late Miss Hope. It is a beautiful plant; the hues somewhat justify the name, but to the touch the leaves are more like a soft fabric, as cloth or velvet. The flowers are of no value, but the foliage is bloom of no mean order, so much so, that everyone stops to admire this handsome plant.

SMALL-FLOWERED HEUCHERA; _Nat. Ord._ SAXIFRAGACEÆ.

From Columbia. Flowers a yellowish-green; leaves nearly round, bluntly lobed, crenate or round toothed, the teeth horned or pointed; the colour is inclined to auburn during autumn, but it varies, and for a botanical description it would be hard to state a particular colour. The gardener, however, will find in this a most useful plant, where different forms and tints of foliage are desirable. Into the sub-tropical garden it may be introduced with good effect. I may add that the leaf stalks are 9in. to 12in. long, also of a rich brown colour, and the leaves are 3in. to 5in. across.

Cultivation and flowering period, as described under _Heuchera_.

_Nat. Ord._ SAXIFRAGACEÆ.

This seems to be a less known or newer variety. If the name has reference to the colour of the foliage, it is not inappropriate. The bold leaves are a dark green, shading to a bronze, then a purple, the whole having a soft downy effect. It is a charming kind.

Cultivation and flowering period, the same as for the _Heuchera_.

CURRANT-LEAVED HEUCHERA; _Nat. Ord._ SAXIFRAGACEÆ.

This is another dwarf kind, producing such leaves as the name denotes. Of this species the only useful feature for a garden seems to be its habit of neatly carpeting the ground under deciduous trees. It has also a remarkably fresh appearance during winter.

Cultivation and flowering period, as for other _Heucheras_.

Heuchera Richardsoni.

RICHARDSON'S HEUCHERA; _Nat. Ord._ SAXIFRAGACEÆ.

A taller variety than _H. Drummondi_. The most striking distinctions are the pale green colour of the young leaves contrasting with the bronzed appearance of the older ones, and the larger size of its flowers, which, however, are green.

Cultivation and flowering period, as for other species.

BLUETS; _Nat. Ord._ GENTIANACEÆ.

Hardy and evergreen. This pretty little shining plant never exceeds a height of 3in. Like most species of this order, both flowers and foliage have much substance and endure for a long time in perfection, but its neat form and bright parts most commend it--it almost sparkles in both leaf and flower. This species, as implied by the specific name, bears a blue flower, but there is a variety (_H. c. alba_ or _H. albiflora_) which bears white flowers, from a specimen of which the illustration (Fig. 52) is drawn, and, as the colour of the flower is the only dissimilarity, a description of the typical form will in all other respects apply to both.

The flowers, which are produced singly on slender stems 2in. high, are composed of a four-toothed calyx; corolla, four petals, or four-toothed and funnel-shaped; when fully expanded each flower is ½in. across, and shows a distinct yellow eye. The leaves of the root are spathulate, those of the stems opposite and lanceolate; all the parts are shown of the natural size in the illustration.

All the known Houstonias are natives of North America; still, our winters seem to kill strong plants. From an impression that the plants were destroyed by insects amongst their roots and foliage, I had several tufts lifted, well shaken out, and divided in the autumn; they were replanted in leaf soil and sand and kept rather moist. When planting them, all amongst the roots was thickly strewn with dry silver sand, so as to leave no space for the lodgment of vermin; the results were fine, fresh, green tufts throughout the following winter, which, however, was not severe; still, the plants not so treated dwindled and were unhealthy, whereas the others were finely in bloom, the subject of the drawing being one of them. These minute plants do well and look well wedged between large stones on rockwork, where they flower nearly all the year round; they also form pretty pot specimens under cold frame treatment; and they may be used with good effect for surfacing the pots in which other hardy but tall and bare stemmed things--such as lilies--are grown.

The mode of propagation has been indicated by the above autumnal treatment.

Flowering period, April to July.

_Syn._ LEPIDIUM ALPINUM; _Nat. Ord._ CRUCIFERÆ.

An alpine species, from South Europe, which may be said to be evergreen in this climate, and, according to my experience of it, flowering throughout the year. Though found in some gardens to be difficult to establish, when it finds a suitable home it becomes a pretty addition.

This alpine seldom exceeds 2in. in height. The flowers are a glistening white and very small, produced in numerous heads, and they are very enduring; the calyx is concave and falls off; the four petals are inversely ovate; the little leaves are deeply lobed, of a pale shining green colour, with plenty of substance; its habit is spreading or creeping. Neither slugs nor any other pests seem to meddle with it. It may be transplanted at any time, and the mode of propagation may be gathered from the following remarks.

Probably because its name implies its alpine character, some may be misled to plant it on rockwork; whether that be so or not, I so tried it, and found it would not grow in such a situation. A bed of dwarf and moisture-loving subjects was being planted, in which a bit of this Hutchinsia was dibbled, and it found a home in the moist vegetable soil. For two or three years I do not remember to have seen it, or the seedlings, without flowers; its pretty, dwarf, rue-like foliage grew so thickly that it threatened to kill the edging of gentianella and such things as _Polemonium variegatum_, the double cuckoo-flower, and the little _Armeria setacea_; it also filled the walks, and its long wiry roots have been eradicated with difficulty. From this it will be seen how much depends, with some plants, on the position in which they are placed.

Hydrangea Paniculata Grandiflora.

LARGE-PANICLED HYDRANGEA; _Nat. Ord._ SAXIFRAGACEÆ.

This dwarf shrub is perfectly hardy and deciduous; it comes from Japan, and is one of the best hardy things I have come across for some time. It is quite a new introduction, and has many fine qualities; the fact of its producing immense clusters of white flowers, 12in. long and 12in. in circumference, as well-established plants, is enough to induce its extended cultivation; but when it is stated that its clusters are numerous and durable, that the shrub begins to flower in summer and continues in great beauty until damaged by frosts, it will doubtless be recorded on the lists of desiderata of those who do not possess it. The usefulness of such a subject is notable not only to the gardener who has a keen eye to artistic effect, but to the lover of showy flowers (see Fig. 53).

The flowers are male and female kinds, and, as is usual with the genus, the fruitful ones are interspersed with unfruitful, being shorter in the stalks and nearly covered over by the latter, which are much larger; in fact, they are not the true flowers from a botanist's point of view, but with the florist it is exactly the opposite; their colour is white, more or less tinted with pink, which, if the autumn season proves fine and dry, becomes purple. As the name denotes, the bloom is arranged in massive panicles, pyramidal form, 6in. to 12in. long, and 4in. to 8in. in diameter. They slightly bend with the great weight, but are otherwise well supported by the woody stems. The latter are somewhat short, seeing they carry such large clusters. The leaves are oval, subcordate (varying), distinctly ribbed, and finely toothed, also varying much in size. The habit of the shrub is much branched, of strong growth, and very floriferous. The flowering shoots issue from the hard wood of the previous season's growth. In the shrubbery it is very attractive, its flowers out-numbering, out-measuring, and out-lasting most of its neighbours. Kept dwarf, what a grand bedder it would make! Grown in pots it is a first-class indoor subject. It has that rare quality, even when in small pots, of being adapted for the company of large ferns, palms, &c., from the great size of its panicles, and I need scarcely say that for cutting purposes it is valuable, more especially in decorations which are not closely viewed.

The culture of this shrub is very simple; it does best in rich loam. The situation should be sunny, that it may well ripen its wood. In order to have clusters of large size, it should be closely pruned, like roses, by which treatment the bush may also be kept in the desired form. Its propagation is by cuttings; they should be of fairly well-ripened wood of the last season's growth. The degree of ripeness, like that of such things as roses and fuchsias, may vary according to the method by which the cuttings are to be treated. Half-ripened shoots will root well in a little heat; the harder wood will root equally well, but more slowly, in the open in sandy loam.

Flowering period, July to end of September.

LARGE-CALYXED ST. JOHN'S WORT, _or_ ROSE OF SHARON; _Nat. Ord._ HYPERICACEÆ.

A very ornamental deciduous shrub, but often green throughout the winter. This I claim the privilege of introducing amongst herbaceous perennials; it is a well-known and favourite "old-fashioned" flower, in fact, a native of Ireland. The old name for it was "Cup St. John's Wort." In July it is in splendid form, and, familiar as we are with it, it never fails to win admiration. How charming are its large, shining, golden blossoms, nestling amongst the bright but glaucous foliage! the bundled tassels composed of numerous filamentary stamens glistening like threads of gold; and though often seen one can never tire of it. As a flower, it is distinct in form, showy, and richly effective.

It grows to the height of 1ft. or 18in.; the flowers are 4in. across, of a rich golden-yellow colour, and produced singly on the very leafy stems which, at the base or at their more woody parts, are square, the upper parts being nearly round. Short flower-stalks issue from the side and near the top, a small new growth being produced in juxtaposition with the blossom, the said growth being composed of half-a-dozen or so smaller-sized leaves of a pale apple-green, charmingly suffused with a glaucous hue. The calyx of five sepals is very large, whence the specific name, and each sepal is nearly round and cupped, whence the old common name, "Cup St. John's Wort"; the five petals are 2in. long and widely apart; stamens very numerous, long, thready, and arranged in tufts. These are very beautiful, and form the most conspicuous part of the flower; like the other seed organs, and also the petals, they are of a rich, glistening, yellow colour. The leaves are closely arranged in pairs, opposite, and nearly sessile; they are 2in. to 3in. long, and about 1in. broad, oval-oblong, blunt, smooth, and leathery. When young, they are as above described, but when older, they are of a dark, shining green colour, and somewhat reflexed. The under sides are finely reticulated or veined, and sometimes the foliage is spotted with brown. The habit of the shrub is neat, the short stems being numerous and semi-prostrate, forming dense, even masses of verdant foliage.

Such a subject as this cannot be too highly esteemed on the score of the merits already set forth; but there are other good qualities which I will briefly refer to presently. There can be little doubt that the fine parts and many uses, decorative and otherwise, of most of the "old-fashioned" flowers have much to do with the high and continued esteem in which they are held. Not one of the least recommendations of this St. John's Wort is that it can be grown with great success under the shade of trees. It is one of the very few subjects that will bloom freely in such situations. It is, therefore, very valuable; besides, as regards its period of flowering, it comes in nicely after the vincas are over. These two genera are, perhaps, the best hardy flowering shrubs we possess for planting in the shade of trees. I scarcely need add that for more open situations, as rockwork and borders, it is in every way suitable.

To the lover of cut flowers this must prove one of the most satisfactory, not only because of its beauty, but also because they are produced for fully three months--into September--and they are sweetly scented, like wallflowers. A flower-topped stem forms a perfect and unique decoration for a lady's hair; sprays in small vases are exquisite, whilst a bowlful for the table (without any other flower) is very fine indeed--let the reader try these simple styles of decoration. Also, mixed with other flowers, it is one of the most telling; none of the yellow exotics can excel it. It is now before me, with a few sprays of the pink sweet pea and a bold spike of the white variety of goat's-rue; the blend is both delicate and effective. As a cut flower it can hardly be misused, provided it is not crowded.

Its culture is simple. Any sort of garden soil suits it, but it prefers a sandy loam. A winter top dressing of stable litter will help to produce greater luxuriance and a longer succession of flowers. It quickly and broadly propagates itself by means of its creeping roots; these may be at any time chopped off, with a sharp spade, in strong pieces, which, if planted in deeply-dug loam, will make blooming specimens for the following season.

Flowering period, July to September.

_Nat. Ord._ CRUCIFERÆ.

This is a hybrid and much improved variety of the well-known evergreen and shrubby Candytuft, often called "Everlasting Candytuft." A more pronounced remove from its parents could hardly be found in any plant or shrub than is this. There are evident improvements in colour, size, and habit, both in foliage and flowers. It is also a robust grower and perfectly hardy, in these respects being very different from _I. Gibraltarica_. None of the shrubby Candytufts can compare with this for usefulness and beauty; it comes into flower in May, and is in its greatest beauty in early June. It remains in fine form for fully four weeks. At first the flowers seem small, but later they form broad masses of dazzling whiteness, the corymbs being the size of a crown piece. Not only is this wholly distinct from its relatives, but it is one of the most useful flowers and evergreen shrubs which can be introduced to a garden. It cannot be planted wrong as regards either soil or situation. It forms a rich surfacing subject, all the year round, to other tall plants, as lilies, &c. It looks well as a front specimen in the shrubbery, makes an effective and neat appearance at the angles of walks, or as an edging it may be cut and trimmed as a substitute for a grass verge; it thrives on sunny or almost sunless outhouse tops, and on rockwork it is superb; moreover, it grows fairly well in reeky towns, and though its white flowers may be soiled the day they open, its bright green leaves and dense habit render it a pleasing object.

The flowers are arranged in flat heads at first, but as the stems become elongated and the succession of buds open, a long round cluster is formed by the old flowers remaining (as they do for weeks), such heads or spikes sometimes being 3in. long. There is much substance in the petals, which causes them to glisten in strong light; the flower stems are produced 5in. or 6in. above the foliage, their total height rarely exceeding a foot. The leaves are numerous, of a dark shining green colour; in length 1½in., and over ¼in. broad near the ends; their shape is spathulate, obtuse, entire, and smooth; the new set of foliage contrasts pleasingly with the old, and its growth is completed during the flowering period; the woody and slender branches are numerous and procumbent.

Besides the positions already mentioned, in which this shrub may usefully be planted, there is none more so, perhaps, than that of rough or unsightly corners, where, if it is provided with a little loam, it will soon adapt its form to the surroundings. The flowers in a cut state are not only sweet-smelling, but very useful where white bloom is needed in quantity, as for church decorations. _I. correæfolia_ can scarcely be said to need cultural treatment, but it is useful to bear in mind that it may be much more finely bloomed if generously treated, which simply consists in nothing more than giving it a sunny place and sandy loam, well enriched with old manure. Specimens so treated, which were cuttings only two years ago, are now 2ft. in diameter, and covered densely with large flowers; and how lovely some of the pretty weeds which have sprung up amongst the bushes, and mingle their flowers among the masses of white, appear--such as Spring Beauty (Claytonia), pink flowers; the Maiden Pink (_Dianthus deltoides_), rose; Self-heal (_Prunella pyrenaica_), purple; and the forget-me-nots! This comparatively new Candytuft is as easily increased as grown, by either layers or cuttings; the latter may be put in almost any time, early spring being the best; if put in in June, no better quarters can be given than under the shade of shrubs, where the soil is sandy loam.

Flowering period, middle of May to middle of June.

GLADDON, GLADWIN, _or_ SPURGE-WORT; _Nat. Ord._ IRIDACEÆ.

A British species, occurring largely in some parts, in shady woods and swampy places near the sea. It is evergreen and of a pleasing form throughout the year. Its flowers are of a dull colour, and not likely to be much esteemed, more especially when in midsummer there are so many beautiful kinds around; still, it merits a place in our gardens. Its handsome berry-like seeds, which are so attractively conspicuous in December, are much more desirable than its flowers, ready as they are for our use at Christmas time.

It grows 2 ft. high, and is a water-loving plant, but may be easily grown in the more moist parts of the garden. The large pod is three-cornered; the husks having turned brown, become divided, and expose to view the large, orange-coloured seeds, which, later, turn to a reddish-brown. They are held in the husks for many weeks and strong winds do not displace them; they are very effective amongst the dark green foliage, and may be cut if desired, as they often are, for indoor decoration. They may be used in a hundred different ways, but never do they show to more advantage than when cut with long stems and placed in a vase with some of their own dark green sword-shaped leaves; these last-named, by the way, may be appropriated throughout the winter as a dressing for other flowers. There need be no difficulty in growing this species, for if the soil is not naturally moist in summer, a thick dressing of rotten stable manure will meet the case. As a matter of fact, my specimen is grown in a bed fully exposed to the sun; the soil is well drained, and stone-crops are grown in the next bed to it; no water is ever given to established plants, and still the Gladwin is well fruited; the soil is deeply tilled, and there is a thick covering of manure. It is easily propagated by division of the roots in autumn or early spring.

Flowering period, June to August.
