Part 11
Its milk-white flowers, which, though very simple, are richly effective, are produced on tall, nude stems, 18in. high, round, wiry, and nearly amber-coloured. They are arranged in a dense spike, 6in. to 8in. long; the corolla is ¼in. across, and composed of five petals; the calyx has a short tube and five sepals; the leaves are heart-shaped, nearly round, evenly toothed, and sometimes glandular; of leathery substance, and somewhat stiff, smooth, shining, and richly veined or nerved. The leaves of various ages differ in colour; the old ones are dark green, conspicuously reticulated; the new, but perfectly-developed ones, are pale green, with a ray of yellowish-green next the edges; the growing ones are nearly red, and all the serrated edges are hemmed with a nearly scarlet line, always brightest at the points of the teeth. This finely-tinted foliage is elegantly disposed by means of the stalks, which bend in various ways; they vary in length from 4in. to 8in., and are all radical; they are round, wiry, and once grooved. The bloom lasts for several weeks in good form, and the foliage is always beautiful, more especially in the autumn, when it glows like polished mahogany. Such a plant can hardly fail to please when well grown, but it must be so developed.
This lovely plant certainly requires a little special treatment, but that is easy and simple; in fact, it scarcely can be called special. It may be put in a few words--damp, but not sour vegetable soil, and very slight shade. My specimen, from which the drawing was taken, is growing in a little dip at the base of a small rockery, below the level of the walk, which acts as a watershed; the soil is nearly all leaf mould--a small portion of loam, and I ought to add that there is a moderate quantity of small charcoal incorporated with it, which will doubtless assist in keeping the soil sweet. There cannot, therefore, be much difficulty in setting up these conditions; the charcoal may not be necessary, but an annual top-dressing with it will meet the case of such plants as grow in low damp situations. The propagation of this species is very easy in the case of well-grown clumps, which, when dug up in the autumn and thoroughly shaken, will come asunder into many small and well-rooted crowns; these only require to be replanted separately, under similar conditions to those by which they were produced. No attempt should be made to divide other than perfectly healthy clumps.
Flowering period, July and August.
Galega Officinalis.
OFFICINAL GOAT'S-RUE; _Nat. Ord._ LEGUMINOSÆ.
A grand "old-fashioned" flower. It is 314 years since this plant was brought from Spain; it is perfectly hardy and herbaceous. Both it and its varieties are among the most useful subjects of the flower garden; they grow to shrub-like bushes, have elegant foliage, and an abundance of bloom, which continues until late autumn. Specimens have a clean and healthy appearance, and though they grow to the height of 4ft., they give no trouble, requiring neither tying nor supports. From their large quantities of flowers they are exceedingly gay; but it is for the handsome stems in a cut state that they should be most prized. These, cut 18in. long, and placed singly in pots or vases, are truly noble, more especially by gaslight.
As will be inferred from the order to which _Galega_ belongs, the flowers are pea-flower-shaped, about ½in. or more long, and the same broad. They are of a pleasing, but undecided blue colour, arranged in long conical racemes, on stout, round stalks, as long as the leaves, which are pinnate, having a terminal odd one. The leaflets are evenly arranged in pairs, mostly in six pairs; they are each about 2in. long, lance-shaped, mucronate, entire, smooth, and glaucous. The floriferous character of the plant may be inferred from the fact that, after the raceme fades, there pushes from the axil a peduncle, which, in a short time, produces many other racemes.
_G. o. alba_, a variety of the above, grows 4ft. high, and is an abundant bloomer; flowers superb for cutting purposes. For culture, see _G. Persica lilacina_.
Flowering period, July to September.
Galega Persica Lilacina.
_Nat. Ord._ LEGUMINOSÆ.
This is a lovely species of _Galega_ imported little more than fifty years ago from Persia. Perfectly hardy; in general form it corresponds with _G. officinalis_. The following are its distinctions: More dense racemes of lilac flowers, a foot less tall, leaflets shorter and broader--in fact, oval, oblong, somewhat twisted or edged up in the arrangement, and often without the terminal leaflet.
The above Goat's-rues are of the simplest culture; they will do in any soil, but if they are liberally treated they will repay it. A fat loam and sunny situation are what they delight in. They may remain year after year in one position, but I find them to do better in every way if they are divided the second year; it should be done in summer, so that they can make a little growth in their new quarters before winter sets in. In order to carry out this, the older plants (I divide half my stock one year, the other half the year following) should be cut over near the ground, though they may be in full bloom. Divide the roots into several strong pieces, and replant them in soil deeply dug and where they are intended to flower; they will bloom finely the following season.
Flowering period, July to September.
Gentiana Acaulis.
GENTIANELLA; _Nat. Ord._ GENTIANACEÆ.
A hardy, evergreen creeper, its creeping stems running immediately under the surface. This is a remarkably beautiful plant, and the wonder is that it is not grown in every garden. The most attractive features, when in flower, of this dwarf Gentian are its immensely large blooms and neat shining green foliage (see Fig. 43). It is easily identified, there being not another species like it, and certainly very few to equal it for beauty and service; it forms one of the best edgings for beds and borders. Many report that it is difficult to grow, which may be the case in some gardens from one cause or other, whilst in many places it runs like quick-grass.
Flowers, dark bright blue, large, long bell-shaped, but not drooping; tube, five-angular, nearly 3in. long; corolla, five-limbed, and an inch or more wide; the stems are seldom more than 3in. long, square, furnished with small opposite leaves, and terminated with one flower on each. That part of the foliage which sends up the flower is arranged in rosette form, the leaves being stout, flat, and acutely lance-shaped. Anywhere or everywhere may this subject be planted; it is always bright, even in winter, and when there are no flowers upon it it forms a rich covering for the otherwise bare ground; its blooms will each keep good a week. They are rarely produced in great numbers at one time, but the plants will continue for a long while to yield them sparingly.
I find _G. acaulis_ to thrive well at the base of rockwork, as an edging to a flat bed, and in the gutters of the garden walks--it likes moisture. To me this is clearly proved by other plants, which, in all respects but one, are treated the same, the exceptional condition being that they are planted on the sloping face of rockwork, where they scarcely grow and never bloom. With reference to soil, rich or silky loam is best for it, but any kind, if sweet and retentive, will do. Its propagation may be effected by division of the rooted creeping stems after they have made four leaves. Very early in spring is a good time to do this, but neither these nor the old plant, if it has been much disturbed, will flower the same season after being so mutilated.
Flowering period, May to July.
Gentiana Asclepiadea.
SWALLOW-WORT-LEAVED GENTIAN; _Nat. Ord._ GENTIANACEÆ.
A tall and beautiful alpine species from Austria, very hardy and herbaceous. It has long had a place in English gardens--fully 250 years--and is described by Parkinson in his "Paradise of Flowers." The tall stems are very showy, having an abundance of shining dark green foliage, amongst which nestle the large and bright purple-blue flowers; it is a subject that looks well at a distance, and, as a rule, flowers with that quality are of the greatest value for borders and cutting purposes.
It grows nearly 2ft. high; the stems are round, erect, short-jointed, and very leafy; the flowers are produced on a third of their length, they are stalkless, and spring from the axils of the leaves in pairs; the calyx is ½in. long, tubular, angled, and having fang-shaped segments; the corolla is also tubular and angled, somewhat bellied, the divisions being deeply cut and reflexed; the whole flower will be fully 1½in. long. The inside of the corolla is striped with white and various shades of blue and purple. The leaves are 2in. long, oval, lance-shaped, distinctly ribbed, somewhat lobed at the base, and stem-clasping, which gives the pair of leaves a joined or perfoliate appearance; the nodes are short, or near together, the lower ones being the more distant, where also the leaves are much smaller; the foliage is a glossy dark green colour, the whole plant having a sombre but rich effect.
From the fact that the long stems are top-heavy and of a brittle character, a sheltered position should be given to this plant, or the wind will snap them off. It ought not to have stakes, as they would mar its good form. A fat loam and a moist situation will suit this Gentian to perfection, and it may be planted with other strong herbaceous things in the borders, where it should be allowed to grow to large specimens. It is one of the quickest growers of its genus, few species of which can be grown in too large quantities. When it is needful to increase this subject, it maybe done more readily than the propagation of some Gentians--the roots are more easily separated. It should, however, be carefully done, and early spring is the best time; or if the autumn should be a dry season and the tops die off early, it may be done then.
Flowering period, July and August.
Gentiana Burseri.
BURSER'S GENTIAN; _Nat. Ord._ GENTIANACEÆ.
A hardy perennial species, of a bold but neat habit, while the flowers and foliage combine in rendering it a first-class decorative subject. It is a recent introduction, having been brought from the Pyrenees in 1820; it is seldom seen in flower gardens, where it certainly deserves to be.
Its flowers are not brilliant, but they are effective from their size, number, and persistency; they are produced in whorls on stout round stems 18in. high, but only on the three or four upper joints. Each flower is 1½in. long, lemon-yellow, tubular, angular, having four to six segments, widely separated, and furnished with a membrane at each separation. The segments, and also the tube, are dotted with dark brown spots; each flower is tightly folded in a somewhat one-sided membranous calyx and borne erect. They occur in pairs mostly, but with several pairs in a whorl. They have very short pedicels, and the whorl is supported by a bract of stem-clasping leaves, cupped, and variously shaped, as ovate and beaked; there are also supplementary bracteoles. The leaves of the root very much resemble the plantain leaf, also that of _G. lutea_, having longish ribbed and grooved petioles or stalks; they are 5in. to 6in. long, and over 3in. broad, egg-shaped, entire, veined longitudinally, and slightly wrinkled; they are of a dark green colour, shining, and of good substance. The leaves of the stems, as already stated, are stem-clasping, and differ in shape. The flowers keep in good form for two or three weeks, and otherwise this rigid bright-foliaged Gentian proves very ornamental.
I find it to do well in vegetable soil in a moist quarter. Most of the members of this genus enjoy plenty of moisture at their roots, and this specimen is no exception. A flat stone will form a good substitute for a damp situation if placed over the roots; besides, such a method of growing this and others of the tall Gentians will allow of their being planted on rockwork, or otherwise, near the more frequented walks, where they must always prove pleasing from their bold and shining foliage, to say nothing of their striking flowers. The propagation of this species should be effected by division of the roots, which are very strong. Each crown should have as much of the more fibrous roots retained as possible, and the parts to be severed should be cut with a very sharp knife; it also ripens seed plentifully.
Flowering period, June to August.
Gentiana Cruciata.
CROSS-LEAVED GENTIAN; _Nat. Ord._ GENTIANACEÆ.
An interesting species from Austria, and one of the "old-fashioned" plants of English gardens, having been cultivated in this country for nearly 300 years. Gerarde gives a faithful and full description of it, which I will quote: "Crossewoort Gentian hath many ribbed leaues spred upon the ground, like unto the leaues of sopewroot, but of a blacker green colour; among which rise vp weak iointed stalks, trailing or leaning towarde the grounde. The flowers growe at the top in bundels, thicke thrust togither, like those of sweete Williams, of a light blew colour. The roote is thicke, and creepeth in the grounde farre abroade, whereby it greatly increaseth." Its height seldom exceeds 10in., and it is to be commended because it is one of the Gentians that are easily grown, and is handsome withal. It may be planted in either vegetable or loamy soil--the common border seems to suit it; it spreads much faster than any of the other Gentians I know, with the exception of _G. acaulis_, and it is in broad masses one sees it to greatest advantage. Propagated by division any time.
Flowering period, June and July.
Gentiana Gelida.
ICE-COLD GENTIAN; _Nat. Ord._ GENTIANACEÆ.
This species comes from Siberia, and has been grown in this country for nearly eighty years. It is a very beautiful species, the whole plant being handsome; it grows nearly a foot high.
The flowers are produced in terminal clusters, one large flower being surrounded by a whorl of smaller ones; they are of a rich purplish-blue inside the corolla, which is rotate; the segments (mitre-shaped) and the spaces between are prettily furnished with a feathery fringe; the wide tube is also finely striped inside; the calyx is tubular, having long awl-shaped segments; the stems are procumbent, firm (almost woody), short jointed, and thickest near the top. The leaves are of a dark shining green colour, from 1½in. to 2in. long, smallest at the root end, and finishing next the flowers with the largest, which are lance-shaped, the lower ones being heart-shaped; they are closely arranged in pairs, are sessile, and at right angles with the stem.
It seems to enjoy a shady damp corner in rockwork, where its distinct forms and neat habit appear to advantage. It should be planted in vegetable soil, such as peat or well-decayed leaves mixed with sand. It cannot endure drought at the roots. It is a slow-growing plant, but very floriferous; the flowers last fully a fortnight in good form, the weather, however rough or wet, seeming to have no effect on them. In a cut state it is exquisite, but those who properly value the Gentians, especially the slow growers, will hardly care to cut away the stems, as, by doing so, not only will the plant be checked, but next year's growth will prove reduced in both number and vigour. It is propagated by root division when in a dormant state. I have also successfully transplanted this kind after it has made considerable growth, but the roots have been carefully guarded against dryness.
Flowering period, June to August.
Gentiana Verna.
SPRING ALPINE FELWORT; _Nat. Ord._ GENTIANACEÆ.
A native evergreen creeper. This plant has many synonymous names in old books. It is now, however, well known by the above Latin name. Let me at once say that it is a matchless gem. Its flowers are such as to attract the notice of any but a blind person. It is said to be rare now in this country, still, I think it is far from being extinct in its wild state. Be that as it may, it is fortunate that it can be easily cultivated, and nothing in a garden can give more pleasure. Its flowers are blue--but such a blue! the most intense, with a large and sharply defined white eye, and though only ½in. across, one on each stem, and 3in. high, they are grandly effective. It has a tubular, angled calyx; corolla five-cut. The leaves are oval, nearly 1in. long, and half as broad; dark shining green and of leathery substance. The radical leaves are crowded into a nearly rosette form.
By many this Gentian is considered difficult to grow, but if a proper beginning is made it proves to be of the easiest management. Very suitable places may be found for it in, not _on_, rockwork, where good fat loam forms the staple soil; little corners, not _above_ the ground level, but on, or better still, _below_ the ground level, are sure to meet its requirements; on the edge of a border, too, where moisture collects in the small gutter, has proved a suitable position for it. But, perhaps, the most successful way of growing it is in pots, for, as with _Trientalis Europa_ and other root creepers, when so treated more compact specimens are obtained. It is important to begin with properly-rooted plants, the crowns of which are often 2in. to 3in. below the surface; from these spring the numerous, bare, yellow, wiry stems, too often taken for roots, whereas the main roots are still deeper, very long for so small a plant, and furnished with silky feeders. Good crowns potted in rich fibrous loam and plunged in sand, fully exposed, with an unstinted supply of water, is the substance of the simple treatment my plants receive the year round; they are still in the 3in. and 4in. pots in which they were placed three years ago, and during spring they are covered with flowers. When a pot is lifted out of the sand in which it is plunged, the fine long silky roots are seen to have made their way through the hole. Spring is the best time to plant.
Flowering period, April to June.
Geranium Argenteum.
SILVERY CRANE'S-BILL: _Nat. Ord._ GERANIACEÆ.
A hardy perennial alpine from the South of Europe, introduced in 1699. It is, therefore, an old plant in this country, and is one of the gems of the rock garden; very dwarf, but effective, as may be seen by the illustration (Fig. 44). The foliage is of a distinct and somewhat conglomerate character, besides being of a silvery-grey colour. Well-grown specimens of this charming Crane's-bill look remarkably well against dark stones. Its flowers are large for so small a plant, and wherever it finds a suitable home it cannot fail to win admiration. In borders of rich soil it is grown to the height of about six inches, but in drier situations, as on the upper parts of rockwork, it is more dwarf.
The flowers are fully an inch in diameter when open, cup-shaped, and striped in two shades of rose colour; the unopened flowers are bell-shaped and drooping; they are borne on long naked pedicels, bent and wiry, oftentimes two on a stem; calyx five-cleft, segments concave; petals five, equal and evenly arranged. The leaves are produced on long, bent, wiry stalks, the outline is circular, but they are divided into five or seven lobes, which are sub-divided and irregular, both in size and arrangement; they have a silky appearance, from being furnished with numerous fine hairs or down. The plant continues to flower for many weeks, but, as may be judged, it is, otherwise than when in flower, highly attractive. To lovers of ornamental bedding this must prove a first-rate plant. As an edging to beds or borders of choice things it would be pleasingly appropriate, and, indeed, anywhere amongst other dwarf flowers it could not be other than decorative.
It thrives well in a good depth of loam, its long tap-roots going a long way down. If, therefore, it is planted on rockwork, suitable provision should be made for this propensity. The propagation of the plant is not so easy, from the fact that it makes large crowns without a corresponding set of roots, and its seed is scarce and often taken by birds before ripened. Moreover, the seedlings do not always come true; still, it seems the only mode of propagation, unless the old plants have plenty of time allowed them to spread and make extra roots. Latterly I have gathered the seeds before the capsules burst--in fact, whilst green--and, after carrying them in the waistcoat pocket for a few days, they have been sown in leaf soil and sand, and germinated freely. When the seedlings have made a few leaves the deteriorated forms may be picked out readily.
Flowering period, May to July.
Gillenia Trifoliata.
_Syn._ SPIRÆA TRIFOLIATA _and_ S. TRILOBA--THREE-LEAVED GILLENIA; _Nat. Ord._ ROSACEÆ.
A hardy herbaceous perennial from North America, imported in 1713. The main features about this plant are its elegant form and rich tints. The illustration (Fig. 45) may give some idea of the former quality, but to realise the latter the reader should see a living specimen in the form of a bold clump. There is a wild beauty about this subject which it is not easy to describe; as a flower it is insignificant, but the way in which the flowers are disposed on the slender stems, blending with a quaintly pretty foliage, neither too large nor dense, renders them effective in their way. It is, however, only as a whole that it can be considered decorative, and it should be well grown.
Although most nearly related to the spiræas the distinctions from that genus are very marked, notably the very slender stems and large flowers, which are produced singly on rather long-bending pedicels, almost as fine as thread, and, like the stems, of a bright brown (nearly ruddy) colour. The flowers form a lax panicle, interspersed with a little foliage. The calyx is a bright brown colour, rather large and bell-shaped. It contrasts finely with the five long, narrow petals, which are white, tinted with red; they are also irregular in form and arrangement, somewhat contorted. The leaves, as implied by the specific name, are composed of three leaflets; they have very short stalks, and the leaflets are all but sessile, lance-shaped, finely toothed or fringed, ribbed, and somewhat bronzed. Perhaps it is most useful in a cut state; the sprays, even if they have but one or two flowers on them, are charming for vase work. I may say the calyx is persistent, and after the petals have fallen they not only increase in size, but turn a fine red colour, and so render the sprays additionally effective.
To grow this plant well it should have a deep soil; it also loves moisture, and, as already hinted, partial shade; it is a steady grower, far from rampant, like the spiræas. This is a capital subject to grow near or under "leggy" shrubs and trees, where, in semi-shade, it is not only at home, but proves very attractive. It may be propagated by division, the best time being early in the year, just before growth commences.
Flowering period, June to August.
Gynerium Argenteum.
PAMPAS _or_ SILVERY GRASS; _Nat. Ord._ GRAMINEÆ.
