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.
Broad-leaved Bellflower; Nat. Ord. Campanulaceæ.
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.
Peach-leaved Bellflower; Old Common Names, "Peach-bels" and "Steeple-bels"; Nat. Ord. Campanulaceæ.
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. p. alba fl.-pl. in two forms that they deserve special notice; they are very desirable flowers, on the score of both quaintness and beauty. I will first notice the kind with two corollas, the inner bell of which will be more than an inch deep, and about the same in diameter. The outer corolla is much shorter, crumpled, rolled back, and somewhat marked with green, as if intermediate in its nature between the larger corolla and the calyx. The whole flower has a droll but pleasing form, and I have heard it not inaptly called "Grandmother's Frilled Cap." The other kind has five or more corollas, which are neatly arranged, each growing less as they approach the centre. In all, the segments are but slightly divided, though neatly formed; this flower is of the purest white and very beautiful, resembling a small double rose. It is one of the best flowers to be found at its season in the borders, and for cutting purposes I know none to surpass it; it is clean and durable. So much are the flowers esteemed, that the plant is often grown in pots for forcing and conservatory decoration, to which treatment it takes kindly.
In the open all the above varieties grow freely in any kind of garden soil, but if transplanted in the autumn into newly-dug quarters they will in every way prove more satisfactory; this is not necessary, but if cultivation means anything, it means we should adopt the best-known methods of treatment towards all the plants we grow, and certainly some of the above Bellflowers are deserving of all the care that flowers are worth.
Flowering period, July to September.
Campanula Pyramidalis.
Pyramidal or Chimney Campanula; Nat. Ord. Campanulaceæ.
This herbaceous perennial is a very old flower in this country; it came from Carniola in the year 1594. It is very hardy, and for several months together it continues to produce its large lively blue flowers, beginning in July and lasting until stopped by frosts. At no time is it in finer form than in September; at the height of from 5ft. to 7ft. it proves richly effective amongst the blooming hollyhocks, where, as regards colour, it supplies the "missing link" (see Fig. 23).
The flowers are a light bright blue colour, and 1in. to 1½in. across. The corolla is bell-shaped, the five divisions being deeply cut, which allows the flower to expand well; the calyx is neat and smooth, the segments long and awl-shaped; the flower stalks are short, causing the numerous erect branches to be closely furnished with bloom during favourable weather. The leaves of the root are very large and stalked, of irregular shape, but for the most part broadly oval or lance-shaped. The edges are slightly toothed, having minute glands; those of the stems are much smaller, sessile, and long egg-shaped; all the foliage is smooth, and of a dark green colour; the main stems are very stout, and sometimes grow to the height of 7ft. Vigorous plants will send up several of these, from which a great number of small ones issue, all assuming an erect habit; blooming specimens are hardly anything else than a wand-like set of flowered stems, and though it is advisable to stake them, I have seen them bend and wave during high winds without damage.
In the borders and shrubbery this is a very effective subject; it is amongst herbaceous plants what the Lombardy poplar is amongst forest trees—tall, elegant, and distinct. Its use, however, is somewhat limited, owing to the stiffness of the stems and the shortness of the flower stalks; but when grown in pots—as it often is—for indoor decoration, it proves useful for standing amongst orange and camellia trees. It has very strong tap roots, and enjoys a deep rich loam. Not only does it look well among trees, but otherwise the partial shade of such quarters seems conducive to finer bloom.
Flowering period, July to October.
C. p. alba is a white flowering variety of the above species; its other points of distinction are its smaller-sized leaves and much paler green colour, by which alone the plants may be easily recognised from the type. This variety may be grown with good effect in pots or the border; it scarcely gets so tall as the blue form, but looks well by the side of it.
The readiest way to increase these plants is to take the young and dwarf growths from the woody crown of the roots, paring off a little of the bark with each. If these are put in sandy loam during the warm growing season and kept shaded for a few days, they will very soon make plenty of roots; this method in no way damages the flowers. Another way is by seed, but seedlings are two years before they bloom.
