Minute and usually prostrate plants, mostly with white, yellow, or rosy flowers, and occurring in multitudes on most of the mountain chains of northern and temperate countries. There are few of these interesting and sometimes very pretty plants that would not grow on the top of an old wall, or thatched house, or stony hank, or bare ground, as well as our common Stonecrop. All grow in any soil, are as easily increased as any weed, and grow anywhere if they are not too much overshadowed by trees and coarse vegetation. Such kinds as S. spurium, S. pulchellum, kamtschaticum, and S. spectabile are among the most ornamental. The last, being a stout herbaceous plant, would be worth associating with such in wild places. There are nearly 100 species of stonecrop in cultivation in Britain.
