The flowers are very lasting, either cut or otherwise; the plants will bloom six or eight weeks.
These subjects will thrive in almost any kind of soil or position, opening their flowers during the dullest weather, and though they like sunshine, they will not wait for it. It is scarcely needful to further describe these well-known flowers, but, as well as the species, there are some bright and beautiful varieties which merit further notice. All the Starworts are easily increased by root division any time.
Flowering period, August to November.
Aster Alpinus.
Alpine Starwort, or Blue Daisy; Nat. Ord. Compositæ.
An exceedingly beautiful and very much admired alpine plant, which does not die down like most of the Starworts, but has woody stems; it is seldom seen more than a foot high, and its large bright purple flowers seem disproportionate. This is one of the plants which should have a place in every garden, and more especially in rock gardens. There cannot well be a more neat and telling subject; the form and size of its flowers are not often seen on such dwarf plants, and it also has the merit of being a "tidy" subject when not in bloom. The illustration (Fig. 18) will give a fair idea of its main features. Its purple flowers, which are fully 2in. across, have for many days an even and well-expanded ray, when the florets curl or reflex; the disk is large, and numerously set with lemon-yellow florets; the flowers are well lifted up on stout round stems, covered with short stiff hairs, and furnished with five or six small leaves; the main foliage is of compact growth, lance-shaped, entire, spathulate and covered with short hairs.
Considering that this plant has been in English gardens for 220 years, and that its merits must be seen by anyone at a glance, it is hard to say why it is not better known; even in choice and large collections it always proves attractive when in flower. The blooms in a cut state are very durable; they not only hold together, but also keep a good colour. Under cultivation it is in no way particular; it will endure anything but being deprived of light; from its dwarf, stout, and shrubby character, it would form a useful and a handsome edging to the larger walks; and by growing it so extensively an enviable supply of flowers for cutting would be at hand.
A stock of young plants may soon be got up by division of strong roots after the flowering season; such pieces as have roots may be planted at once in their permanent quarters; the rootless parts should be dibbled into light sandy loam and shaded with branches for a week or two.
Flowering period, June and July.
A. a. albus is a white-flowered variety, blooming about the same time. There does not appear to be that vigour about it which characterises the type; this, however, is not the only shortcoming; when compared with the rich purple flower, the white one, with its large yellow disk, appears, to say the least, a questionable improvement.
Aster Ptarmicoides.
Bouquet Starwort; Nat. Ord. Compositæ.
This Starwort is a very recently-imported species from North America. Like many other things which have proved worthless as decorative flowers, this was highly praised, but for a while its weedy-looking foliage caused suspicion; after becoming well established, it flowered, and, I am glad to say, proves a most distinct and useful Starwort. Its small white flowers much resemble the field daisy, but they are borne on densely-branched stems in hundreds; in fact, the plant, which grows nearly 2ft. high, seems to be nearly all flowers. Each one has a single ray of shining white florets, narrow and separate. Those of the disk are of a canary-yellow colour; the imbricated calyx is pear-shaped; pedicels slender, bent, wiry, and furnished with very small leaves; main stems hispid, woody, and brittle. The leaves of the root are 2in. to 4in. long, smooth, entire, linear, almost grass-like; those of the stems much less, becoming smaller as they near the flowers; they are somewhat rough, partaking of the quality of the stems. The habit of the plant is much branched, the spreading clusters of flowers being six or ten times the size of the plant, so that it becomes top-heavy; it blooms for many weeks, and is not damaged by coarse weather. Amongst other Asters it shows to advantage, flowering earlier than most of them, but lasting well into their period of bloom. It is sure to prove a useful white autumnal flower; small sprays when cut look better than on the plant, as they are then seen to be well spread and rigidly held by means of their wiry stalks; they have the scent of Southernwood. It grows well with me in ordinary garden loam, the situation being well exposed to the sun. It may be readily propagated by root division.
Flowering period, August to October.
Bellis Perennis.
Common Perennial Daisy; Nat. Ord. Compositæ.
This native plant, the commonest flower of the field and wayside, and the weed of our grass-plots, is the parent form of the handsome and popular double kinds seen in almost every garden. Well known as these flowers are, it may prove interesting to learn a little more about the fine large double crimson and white kinds—their treatment, for instance—in order to have abundance of flowers during the earliest months of the year; and the uses to which they may be most advantageously put; for, common as are the Daisies, they are, without doubt, amongst the most useful flowers we possess. First, I will briefly give the names and descriptions of the more distinct varieties.
B. p. aucubifolia is the Double Daisy, having a beautifully variegated foliage, mottled with golden-yellow in the way of the aucuba.
B. p. fistulosa.—This is the double crimson or pink Daisy, having its florets piped or quilled (see Fig. 19).
B. p. hortensis embraces all the double forms raised and cultivated in gardens, no matter what colour, and so distinguished from the typical form of the fields.
B. p. prolifera is that curious and favourite kind called "Hen and Chickens." The flowers are double, and from the imbricate calyx of the normal flower there issue a number of smaller Daisies having straggling florets; the whole on one main stalk presenting a bouquet-like effect.
These kinds, the specific names of which are not only descriptive, but amply embrace the group, are much added to by flowers having other names and minor distinctions, the latter, for the most part, being only shades or mixtures of colour—as crimson, pink, white, and bicolours. The florets in many kinds are exceedingly pretty, from the way in which they are tipped and shaded; notably, a new variety that was sent me under the name of Dresden China. These sorts having different tints are usefully named with "florists'" names—as Pearl, Snowball, Rob Roy, Sweep, Bride, &c. I may say that I have long grown the Daisy largely, Bride and Sweep being the favourite kinds; both are robust growers, very hardy and early. Bride is the purest white, with florets full, shining, and well reflexed; rather larger than a florin, and when fully developed has a half globular appearance; another good point is its flower stalks being 4in. to 5in. long, which renders it serviceable as cut bloom. Sweep is not quite so large, though a good-sized Daisy, it also opens more flat; its colour, however, is first rate, it is the darkest crimson Daisy I ever saw, is of a quilled form and very full. Its chief
