Hardy Perennials and Old Fashioned Flowers Part 13

This is said to be a British species, but it is a doubtful, as well as somewhat scarce one. Though but a small plant of the height of 6in. or 8in., it is very effective, being compact with finely-cut foliage of a pale glaucous green, and the stems pleasingly tinted. For some weeks in early spring it forms a graceful object on rockwork, where it seems to thrive well.

The flowers, which are purple, are not showy; still, they are effective from the way in which they are borne, as the ill.u.s.tration (Fig. 30) will show. Its specific name is in reference to its root, which is bulbous and solid. Many of the Fumitories have remarkably hollow roots, and one of the old names of this genus is written "Hollowe roote." When the flowers fade the whole plant withers, nothing being left but the bulbous roots to complete their ripening; still, this should not hinder its extensive cultivation, because it not only appears in its best form when flowers are rare, but also because it is so pleasingly distinct.

(One-half natural size.)]

I find it to do well on rockwork, also in well-drained borders of light loam. It should be allowed to increase until it forms good-sized tufts, which it soon does. To propagate it, it is only necessary to divide the tubers any time from July to October.

Flowering period, February to May.

Crocus Medius.

_Nat. Ord._ IRIDACEae.

This is a charming kind, seldom seen and, perhaps, little known; the name would imply that it is a variety having equal traits of two other forms. It blooms in January and the flowers appear without any foliage.

So well is the Crocus known, it will only be needful to state the more striking features of the one under notice.

The flowers are produced on tubes 3in. to 5in. long, and stoutly formed; the colour is a shaded lilac-purple, striped with darker lines; the petals or divisions of the perianth are 1in. long and in. broad, s.h.i.+ning or satiny, and become well expanded during the short moments of winter suns.h.i.+ne; the stamens are half the length of perianth, of a fine deep orange colour, and covered with a thick coat of pollen all their visible length. In rich contrast with these is the style, with its tuft of filaments of a bright orange scarlet colour. From this description it will be seen that the flower is a rather small Crocus, but from the soft tints of the perianth, and more p.r.o.nounced and bright colours of the seed organs, it is one of much beauty. These features, added to the facts of the bloom appearing in winter and having the scent of wild roses, are sure to render it a favourite kind wherever grown. The leaves are short and narrow, almost gra.s.sy.

It enjoys a light but rich loam and sunny aspect, and increases itself freely by offsets of the matured corms, clumps of which may be divided after the foliage has withered.

Flowering period, January.

Cyananthus Lobatus.

_Nat. Ord._ POLEMONACEae.

A small plant with a large flower, a veritable gem; no collection of choice alpines can be complete without this species. A native of Chinese Tartary, brought to this country in 1844, where it proves perfectly hardy in the most exposed parts of the open garden; it is herbaceous and perennial; its large and brilliant flowers are very beautiful, but all its other parts are small, as may be seen in the ill.u.s.tration (Fig. 31).

It is seldom met with except in collections of rare plants, but there is no reason why it should not be more commonly grown, as its requirements are now well understood. It is not a showy subject, but, when examined, it proves of exquisite beauty.

The flowers are of a bright purple-blue colour, over an inch across, the petals being of good substance, tongue-shaped, and falling backwards, when the china-like whiteness about the top of the tube becomes more exposed; the calyx is very large, nearly egg-shaped, having five finely-pointed and deeply-cut segments; the bulky-looking part, which has an inflated appearance, is neatly set on a slender stem, and densely furnished with short black hairs of even length; this dusky coat has a changeable effect, and adds not only to the character, but also to the beauty of the flower. The small attenuated leaves are alternate and laxly arranged on the flower stems, which are 6in. to 12in. long, round, and nearly red. Each leaf is less than 1in. long, distinctly lobed with five or more lobes, and all the edges are turned back, causing the foliage to appear thick and well finished; the foliage of the stems not bearing flowers is more closely set. The habit of the plant is proc.u.mbent; stems contorted, and producing solitary flowers.

[Ill.u.s.tration: FIG. 31. CYANANTHUS LOBATUS.

(Natural size.)]

It should be grown on rockwork, where its stems can nestle between the stones and its roots find plenty of moisture, as in a dip or hollowed part; the long and fleshy roots love to run in damp leaf mould and sand. The position should be open and sunny, in order to have flowers.

Cuttings may be taken during summer, and struck in sandy peat kept moist, or strong roots may be divided. The latter method is the less desirable, not only because of jeopardising the parent stock but also because strong roots show to greater advantage when not separated.

Flowering period, September and October.

Cypripedium Calceolus.

ENGLISH LADY'S SLIPPER; _Nat. Ord._ ORCHIDACEae.

This well-known terrestrial orchid is a rare British plant, very beautiful, and much admired, so much so, indeed, that many desire to grow it. It happens, however, that it seldom thrives under cultural treatment, and seems to prefer a home of its own selection, but its habitats are said now to be very few in Great Britain, it having been hunted out and grubbed up everywhere. Fortunately, it can be grown in gardens, and in good form, though rarely seen thus. To see well-grown flowers of this orchid either makes us feel more contented with our own climate or strongly reminds us of others where the most gorgeous varieties of flowers and fruit grow wild. It is large and striking, fragrant, and very beautiful; no one can see it, especially in a growing state, without being charmed by its freshness and simplicity; it also forms one of the finest specimens for the student in botany, and in every way it is a plant and flower of the highest merit (see Fig. 32).

It should be in all collections of choice plants, and every amateur should persevere until he succeeds in establis.h.i.+ng it.

[Ill.u.s.tration: FIG. 32. CYPRIPEDIUM CALCEOLUS.

(One-third natural size.)]

Under cultivation it flowers in early May, at a height of 9in. to 12in.; the flowers are composed of a calyx of three brownish-purple sepals, which have only the appearance of two, from the fact of the lower two being joined or grown together, and even so combined they are somewhat less than the upper sepal. The division may be observed at the tips, though in some specimens it is microscopic--in the one now by me it is hardly the eighth of an inch. Two petals; these are cross-form in relation to the sepals, of the same colour, and a little longer--about 2in.--narrow, drooping, pointed, and slightly twisted when a few days old; lip, "blown out like a slipper," shorter than the sepals, compressed, richly veined, and lemon yellow. The seed organs are curious, the stigma being foot-stalked, peltate, and placed between and above the anthers. The leaves are pale green, very hairy, many-ribbed, stem-clasping, alternate, ovate, and slightly wavy; the lower ones are 5in. or 6in. long and 2in. to 3in. wide, and pointed. The root is creeping, the fibres stout, long, wiry, and bent. During spring the plant makes rapid growth, and seldom bears more than one flower; for the first time a plant produced two with me in 1882. They are sweetly scented, like the primrose.

Many amateurs, who have otherwise proved their knowledge of the requirements of plants by growing large and choice collections, have failed to establish this after many trials; and were it not for the fact that with me it is growing in various positions and under different modes of treatment, and that it has so grown for several years, I think I should not have ventured to give hints to experienced horticulturists.

In my opinion, four conditions are strictly necessary in order to establish this native orchid in our garden: (1) A strong specimen with a goodly portion of the rhizoma attached; (2) Firm or solid planting during autumn; (3) Moist situation; (4) Shade from the mid-day sun.

Further information may be best given by stating the _modus operandi_: Several years ago a number of good roots were planted in sandy loam of a calcareous nature. They were put in somewhat deeply, the roots carefully spread out, and the soil made solid by repeated waterings, the position being shaded by an apple tree. They are now well established, and only receive a top dressing of leaves and manure to keep them cool and moist in summer. At the same time a number were potted deeply in loam, peat, and broken oyster sh.e.l.ls; when filling in the compost, it, too, was washed to the roots, so as to make all solid by frequent applications; the pots have always been kept in cool and shady quarters, and plunged; they bloom well every season. I have likewise found another plan to answer well. In a moist corner make up a low-lying bed of sand and peat, mostly sand, plant 9in. deep, and make all solid, as before, by water.

When the growths appear on the surface, water with weak liquid manure, and if shade does not exist from the mid-day sun, some should be provided; in this way I am now growing my finest specimens; but if once the roots become dry, the plants will suffer a serious check. I feel equally confident that the roots enjoy a firm bed, but it should be of such material that they can freely run in it.

Flowering period, May and June.

Daphne Cneorum.

TRAILING DAPHNE; _Common and Poetical Name_, GARLAND FLOWER; _Nat. Ord._ THYMELACEae.

An alpine shrub from Austria; dwarf, evergreen, and having a tendency to creep. It is deservedly a great favourite; it wins admiration by its neat and compact form and its dense and numerous half-globular heads of rosy pink flowers, which are exceedingly fragrant, in the way of the old clove carnation, but more full.

[Ill.u.s.tration: FIG. 33. DAPHNE CNEORUM.

(One-fourth natural size; (1) flower, full size.)]

The flower buds are formed during the previous season of growth, like those of the rhododendron; for many days before the flowers open the buds have a very pleasing appearance, being closely packed and coral-like; when all the florets are expanded they form a half-globular head 1in. to 1in. across, being of a lively pink colour. The flowers are composed of a tubular calyx, four-parted; leaves inversely ovate, lanceolate, pointed, and entire; about an inch long, and narrow; of a dark green colour and much substance, being arranged in circular form on the round and somewhat wiry, tough stems, which in time become very long and bare.

In order to grow this shrub well, three conditions are needful, viz., a moderately pure atmosphere, exposure to full suns.h.i.+ne, and plenty of moisture; it also prefers peat or vegetable soil, but this is not strictly needful if the other conditions are present. I have grown the specimen, from part of which the ill.u.s.tration (Fig. 33) was drawn, for four years in rich loam, without a particle of peat, but the roots have been protected against drought by large stones at the base of small rockwork. Doubtless, peat, where it is plentiful, used in addition to the above compost, would prove beneficial. After a few years' growth in one position, bushes which have become long and bare in the stems may be transplanted with advantage, laying in the stems to a moderate depth, from which new roots will issue the first season; this is also the readiest way of propagation. February or September would be suitable months for such operation, but the latter would probably interfere with its flowering at that time, when frequently a second but spare crop is produced.

Flowering periods, April and May, and again in September.

Daphne Mezereum.
