Hardy Perennials and Old Fashioned Flowers. John George Wood
of bloom. All such prostrate forms not only preserve dwarf winter flowers from the mud, but otherwise give effect to the borders. This bulb thrives best in light soil, well drained; in sheltered nooks it may be had in flower a month earlier than in exposed parts. Under such conditions it increases very fast, and the bulbs may be transplanted with advantage every other year after the tops have died off. In stiff or clay-like soil it dwindles and dies.
Flowering period, January to March.
Calthus Palustris Flore-pleno
The typical, or single-flowering variety of this plant is a British species, and a rather common one; but the pleasing habit and bright, finely-formed, orange-yellow flower of this double kind renders it a suitable plant for any garden. It is herbaceous and perennial, and loves boggy situations. It is, however, very accommodating, and will be found to do well in ordinary garden soil, especially if it be a stiffish loam; clayey land is well adapted for it. No matter what kind of weather prevails, it has always a neat and fresh appearance. By the illustration (Fig. 22) the reader will doubtless recognise its familiar form. As already stated, its flowers are orange-yellow, very full, with petals evenly arranged; they are 1in. across, and produced on round, short, hollow stems, seldom more than 9in. high. The forked flower stalks are furnished with embracing leaves, differing very much from the others, which are stalked, heart-shaped, nearly round, and evenly-toothed. All the foliage is of a rich dark shining green colour. Strong specimens produce flowers for a long time, fully two months, and frequently they burst into blossom again in the autumn. Individual flowers are very lasting, and, moreover, are very effective in a cut state. It is a robust grower, providing it is not in light dry soil; it seems with me to do equally well fully exposed to sunshine and in partial shade, but both positions are of a moist character.

(One-half natural size.)
It has long fleshy roots, which allows of its being transplanted at any time, early spring being the best, to increase it. The crowns should be divided every three years, when there will be found to be ample roots to each one.
Flowering period, April to June.
Calystegia Pubescens Flore-pleno
This double Convolvulus is a somewhat recent introduction from China; it is hardy and perennial. So distinct are its large flesh-coloured flowers that they are often taken at the first glance, when cut, for double pyrethrums or chrysanthemums, but, seen in connection with the plant, the form of foliage and climbing or twining habit of the bindweed soon enable the most casual observer of flowers to recognise its genus.
The flowers are 2in. to 3in. across, petals long, narrow, wavy, and reflexed; these are well held together by the five-parted calyx, further supported by a bract of two small but stout leaves. The flower stalks are round and wiry, 3in. or 4in. long; they are produced all along the twining stems, which are only of the moderate length of 5ft. or 6ft. The leaves are of the well-known Convolvulus form.
I find it a good plan to grow this subject amongst tall and early flowering plants, such as lupins, foxgloves, and lilies, the old stems of which form ample supports for the climber; moreover, they are rendered less unsightly from being thus furnished anew with leaf and flower, even though not their own. Another method is in early summer to place a short twiggy branch over the pushing growths; it will soon become covered, and if not too large, the ends of the shoots will slightly outgrow the twigs and hang down in a pleasing manner. The plant should be started in light sandy loam and have a warm situation, otherwise flowers will be scarce and the whole specimen have a weedy appearance. When once it becomes established, it will be found to spread rapidly by means of its running roots, which, unless checked, will soon become a pest. I simply pull out all growths except such as shoot up in the desired position, and so continue to treat them as weeds throughout the growing season. Stems furnished with flowers a yard or more long, in a cut state, make rich festoons; single blooms (the smaller ones) look well as "buttonholes," being neat and effective, without gaudiness. I ought to state that a succession of flowers is kept up for fully three months; this fact adds not a little to the value of this handsome flesh-coloured bloomer. Roots may be transplanted at any time; the smallest piece will produce a blooming plant the first season, if put into a proper soil and situation.
Flowering period, July to September.
Campanula Grandis
A hardy herbaceous perennial from Siberia, growing to a height of 3ft. Its flowers are large, bright, and numerous; well-established clumps will present masses of bloom for more than a month with average weather. As a large showy subject there are few plants more reliable, or that can in any way excel it, more especially for town gardens. It is a rampant grower, quickly covering large spaces by means of its progressive roots; in gardens or collections where it can only be allowed a limited space, the running habit of the roots will doubtless prove troublesome, and often such free growers, however handsome they may be otherwise, are esteemed common, which should not be. The proper thing to do would be to give these vigorous and fine flowering subjects such quarters as will allow them their natural and unrestrained development.
The flowers of C. grandis are more than 1in. across the corolla, the five segments being large and bluntly pointed, of a transparent purple-blue colour, and very enduring; they are arranged on short stalks, which issue from the strong upright stems. They form little tufts of bloom at every joint for a length of nearly 2ft.; the succession, too, is well kept up. Buds continue to form long after the earliest have opened. The leaves are 4in. to 8in. long and ¾in. wide, lance-shaped, stalkless, and finely toothed. They are arranged in round tufts on the unproductive crowns, and they remain green throughout the winter.
As regards soil, any kind will do; neither is the question of position of any moment beyond the precaution which should be taken against its encroachments on smaller subjects. In the partial shade of shrubs it not only flowers well but proves very effective. Useful as this plant is in the garden, it becomes far more so in a cut state. When it is needful to make up a bold vase or basket of flowers for room decoration, it can be quickly and effectively done by a liberal use of its long, leafy, but well-bloomed spikes; five or six of them, 2ft. to 3ft. long, based with a few large roses, pæonies, or sprays of thalictrum, make a noble ornament for the table, hall, or sideboard, and it is not one of the least useful flowers for trays or dishes when cut short. Propagated by division at any time, the parts may be planted at once in their blooming quarters.
Flowering period, June and July.
Campanula Latifolia
A British species, very much resembling C. grandis, but somewhat taller, and flowering a little earlier; the latter quality has induced me to mention it, as it offers a fine spike for cutting purposes before the above is ready.
Culture, uses, and propagation, the same as for C. grandis.
Flowering period, June and July.
Campanula Persicifolia
This good "old-fashioned" perennial has had a place in English gardens for several hundred years; it is still justly and highly esteemed. It is a well-known plant, and as the specific name is descriptive of the leaves, I will only add a few words of Gerarde's respecting the flowers: "Alongst the stalke growe many flowers like bels, sometime white, and for the most part, of a faire blewe colour; but the bels are nothing so deepe as they of the other kindes, and these also are more delated and spred abroade then any of the reste." The varieties include single blue (type) and white, double blue, and different forms of double white.
In all cases the corolla is cup or broad bell shaped, and the flowers are sparingly produced on slightly foliaged stems, 18in. to 3ft. high; there are, however, such marked distinctions belonging to C.
