All the Dodecatheons make a rapid growth in spring, their scapes being developed with the leaves; the genus will continue in flower for two months, after which time, however, their foliage begins to dry up. They should, therefore, be planted with other subjects of later growth and blooming, so as to avoid blank spaces. The overshading foliage of other things will do them no harm, as it will be only for a season. The position should be moist and somewhat sheltered from high winds, or the stout and tender flower stems will be snapped off. The soil should be of a vegetable character and retentive of moisture. My specimens are grown in leaf soil and loam, in a dip of small rockwork. All the kinds were planted that a large flat stone, which we had ready, would so fit to, or over, them as to secure their roots against drought. This I find a good plan with moisture-loving subjects, where suitable positions are not otherwise readily offered. Besides, the varieties so grown have a pleasing appearance, and for purposes of comparison are very handy. Their propagation is easy. The crowns may be divided either in spring or autumn, the latter being the best time, as then probably each piece will flower the following spring.
Flowering period, April to June.
Dodecatheon Meadia.
Shooting Star, or American Cowslip; Nat. Ord. Primulaceæ.
Fig. 34. Dodecatheon Meadia.
(One-sixth natural size.)
A distinct and pretty herbaceous perennial, very hardy and floriferous. Those who do not readily recognise it by any of the above names, may do so by the illustration (Fig. 34). It has long been grown in English gardens—nearly 150 years—its habitat being North America. Not only does it do well in this climate, but since its introduction several improved varieties of this species have been produced, which are both good and distinct. A brief notice of them will not be out of place here, but first the general description may as well be given.
The flowers much resemble the Cyclamen, but they are only about one-fourth the size; the calyx is five-parted; the corolla has five stout petals inserted in the tube of calyx; they are well reflexed and rather twisted; their colour is purplish-lilac, but at the base of the petals there is a rich blending of maroon and yellow. The seed organs are very long, compact, and pointed, giving the appearance of shooting stars. The flowers are arranged in fine clusters on a scape more than a foot high, each flower having a rather long, wiry, and gracefully bending pedicel; all of them spring from one centre. The leaves are radical, oblong, smooth, dented, and wavy, about 8in. long and nearly 3in. broad.
D. M. albiflorum I do not grow, but from what I remember of it, it differs from the above only in being less vigorous and in having white flowers.
