A very hardy alpine from France, and one of the most floriferous subjects that can be placed on rockwork, where should be its position. During a single season it is no uncommon thing to see a small plant grow into a large cushion 2ft. in diameter, and only 6in. or 9in. high. In planting it this fact should not be overlooked, not only for the sake of giving it plenty of room, but also in order that less vigorous subjects near it may not become overgrown; it blooms all summer, and though the flowers are small and not at all bright, their numbers render it attractive.
The flowers, which are about ½in. across, are of a pink colour, and produced on many-branched prostrate stems; the calyx is five-toothed; the corolla is formed of five flat petals; the leaves are small, basil-like, oval-lance shaped, entire and smooth; the general appearance of the plant when in bloom is that of a compact mass of small leaves and flowers, the latter predominating.
It will grow in any kind of soil, but prefers that of a vegetable character, with its roots amongst large stones; but, strictly speaking, it needs nothing but an open situation and plenty of room to spread. It ripens an abundance of seed, and there is not a better mode of propagation than its own; hundreds of stout seedlings appear the following spring around the parent plant, and these may then be transplanted, and they will flower the same season.
S. o. splendens is a variety of the above very much improved indeed; and though one cannot discard the good old plant for its very recent offspring, the former is certainly very much eclipsed. Splendens has foliage slightly different, but its flowers are much larger and brighter; and though it may not be quite so vigorous, in this case that may be considered an improvement. It is said to come true from seed.
Flowering period, May to August.
Saxifraga Burseriana.
Burser's Saxifrage; Nat. Ord. Saxifragaceæ.
A hardy evergreen alpine. A native of Carniola, not long discovered, and quite new to English gardens. Though it belongs to a very extensive genus, it is a distinct species; many of the Saxifrages are not so, neither are they sufficiently decorative to merit a place in any but large or scientific gardens. This one, however, is a truly handsome kind, and its flowers are produced amid the snow and during the bleak and dull weather of mid-winter.
The plant in form is a dense cushion of little spiked rosettes, of a dark green colour, slightly silvered. The flowers are produced on bright ruddy stems 3in. high, and are creamy white, nearly the size of a sixpence. Small as the plant is, a moderate sized specimen is very attractive, especially before the flowers open, when they are in their prettiest form. They open slowly and endure nearly two months.
