fitted for lines or borders where other strong growers are admitted. In a cut state the flowers are very useful; they are strongly scented, something like the lilac, with just a suspicion of Valerian in it. I ought not to omit mention of its extra brightness as seen by gaslight—this fact adds much to its value for indoor decoration.
It may be grown in any kind of garden soil, needing nothing at any time in the way of special treatment; but if it is supplied with a little manure it will pay back with interest, in the form of extra-sized bunches and brighter flowers.
C. r. albus is a white-flowering kind of the above; its main points of difference are its paler green foliage, smaller sized corymbs, shorter growth, and rather later season of bloom.
C. r. coccinea is another kind; the specific name is misleading. It is not scarlet, but nearer a rose colour, and when compared with the typical colour it appears much inferior; still, it is a good variety. All the three colours, when grown side by side, are very showy when in bloom.
This species, with its varieties, may be easily propagated by root divisions at any time from late summer to spring; the long fleshy roots should not be broken more than can be helped; every piece with a crown on it will make a flowering plant the first season.
Flowering period, June to September.
Cheiranthus Cheiri.
Common Wallflower; Nat. Ord. Cruciferæ.
This well-known evergreen shrub (see Fig. 24) is more or less hardy in our climate, according to the conditions under which it is grown. Although a native of the South of Europe, it rarely happens, however severe the winter may be in this country, that we are totally deprived of the favourite bouquet of Wallflowers in winter or early spring, while it is equally true that, during the hard weather of one or two recent winters, in numerous gardens every plant was killed. In favourable seasons its blooms are produced throughout winter, but the full blow comes in April. Three hundred years ago it was known by its present name; in this respect it is a rare exception, as most flowers have many and widely different names, especially the "old-fashioned" sorts, so that often the varied nomenclature hinders the identification of the species. At one time the Wallflower was called the "Gillyflower," but the name is now only applied to a biennial and single-flowered variety of the stock—a near relation of the Wallflower. More than 200 years ago Parkinson wrote, "Those Wallflowers that, carrying beautiful flowers, are the delights and ornaments of a garden of pleasure."
Of its well-known beauties, as regards its form, colour, varieties, and delicious perfume, description is needless, though I may say, in passing, that its fragrance renders it of value to those whose olfactory nerve is dead to the scent of most other flowers.
Two errors are frequently committed in planting the Wallflower; first, at the wrong time, when it is nearly a full-grown specimen and showing its flowers; next, in the wrong way, as in rows or dotted about. It should be transplanted from the seed beds when small, in summer or early autumn, and not in ones and twos, but in bold and irregular groups of scores together; anything like lines or designs seems out of harmony with this semi-wildling. There is another and very easy method which I should like to mention, as a suggestion—that of naturalisation; let those near ruins, quarries, and railway embankments and cuttings, generously scatter some seed thereon during the spring showers, when the air is still; in such dry situations this flower proves more hardy than in many gardens. Moreover, they serve to show it to advantage, either alone or in connection with other shrubs, as the whin, which flowers at the same time; here, too, it would be comparatively safe from being "grubbed up."
Flowering period, January to June.
Cheiranthus Marshallii.
Marshall's Wallflower; Nat. Ord. Cruciferæ.
A distinct and very hardy hybrid, being shrubby and tree-like in shape, but withal very dwarf. From the compact habit, abundance and long duration of its flowers, it is well suited for showy borders or lines. It is not yet well known, but its qualities are such that there can be no wonder at its quickly coming to the front where known.
It differs from the common Wallflower in being more dwarf and horizontally branched, while the leaves are more bent back, hairy, and toothed; immediately below the floriferous part of the stem the leaves are more crowded, the stems more angular, the flowers much less, not so straggling, and of a dark orange colour. Other hybrids in the same way are being produced, differing mostly in the colour of the flowers, as lemon, greenish-yellow, copper, and so on.
Plants a year old are so easily raised from cuttings, and form such neat specimens, that a stock cannot be otherwise than very useful in any garden; besides, they lift so well that transplanting may be done at any time. My finest specimens have been grown from their cutting state, on a bed of sifted ashes liberally mixed with well-rotted stable manure; in such light material they have not only done well, but, when a few roots were required, they lifted large balls without leaving any fibre in the ground. To have good stout stock before winter sets in, slips should be taken from the old plants as soon as they have done flowering; dibble them into light but well enriched soil, and give water in droughty weather only.
I ought to mention that this dwarf Wallflower, and also its allied kinds, are capital subjects for very dry situations; on old walls and the tops of outhouses they not only do well, but prove decorative throughout the year. In such places plants will live to a great age, and sow their own seed freely besides.
Flowering period, May and June.
Chionodoxa Luciliæ.
Snow Glory; Nat. Ord. Liliaceæ.
A hardy bulbous perennial, from Asia Minor. It has only been cultivated about four years in English gardens; still it has been proved to be as hardy as the squills, which it very much resembles. Mr. Maw, who discovered and introduced it, found it "near the summit of the mountain," which (though it is a native of a much warmer climate than ours) may account for its hardy character. That it is a most beautiful flower is beyond doubt, but there are those who think it has been overpraised. It should not, however, be forgotten that Mr. Maw's description of it was from a sight of it in masses, a state in which it can hardly have been judged yet in this country, as until very recently the bulbs were very expensive. It has, however, taken kindly to our climate, and is likely to increase fast, when it may be seen to greater advantage.
It grows to the height of 6in. or 8in.; the flower scapes, which are rather slender, are somewhat shorter than the foliage, the flowers being longer in the petals than the squills, almost star-shaped, and nearly 1in. across; later on they reflex. Their colour is an intense blue, shading to white in the centre of the flower. The flowers are produced in numbers, from three to six on a stem, having slender pedicels, which cause the flowers to hang slightly bell fashion. The leaves, from their flaccidness and narrowness, compared with the squills, may be described as grassy. The bulbs are a little larger than the kernel of a cob nut, nearly round, having satiny skins or coats.
It may be grown in pots, and forces well if allowed first to make good roots, by being treated like the hyacinth. It should be kept very near the glass. It has also flowered fairly well in the open border fully exposed, but in a cold frame, plunged in sand and near the glass, it has been perfection. Single bulbs so grown in "sixties" pots have done the best by far.
All the bulbs hitherto experimented with have been newly
