CRASSULACE.^. 1 25 



selected; but there are some tender ones, with peculiar and 

 variegated leaves, that are valuable ornaments of the flower- 

 garden ; and some of the hardy ones are not inferior to these 

 for the same purpose, and are becoming popular. 



S. acre {CoJtnnon Stonecrop). — This is a well-known British 

 plant, abundant in many parts of the country on rocks and dry 

 banks and walls. It forms close masses of weak trailing stems, 

 thickly crowded with bright green, thick, short, almost globular 

 leaves. The flower-stems are nearly erect, about 2 inches high; 

 flowers bright yellow in small crowded cymes. This is an in- 

 valuable species for clothing old walls, stones, and dry sandy 

 banks. There is a very pretty variegated form, which in spring 

 assumes the appearance of a carpet of gold when planted in 

 breadth; the tips of the shoots become bright golden yellow 

 as soon as growth begins in spring. It is therefore a valuable 

 plant for spring massing in dry light soil, but does not succeed 

 so well in richer and wetter soils ; it is quite easy, however, on 

 a small scale, to provide a dry enough position for it under any 

 circumstances, and the plant is well worth an effort. Both the 

 species and variety are capital plants for suburban gardens ; 

 and although the species manages to make a tolerable existence 

 on the face of a dry rock, it does not object to richer pabulum, 

 and luxuriates in any soil not absolutely boggy. The variety 

 is found in nurseries under the names S. a. variegatum and S. 

 a. aureiwi. 



S. album ( White Sfonecr op). — An elegant species, with numer- 

 ous barren stems matting and creeping on the surface of the 

 ground. The leaves are crowded, fleshy, and cylindrical. The 

 flower-stems are erect, about 6 inches high, bearing pretty 

 corymbs of pure white flowers, in some individuals also pink. 

 They appear in June and July. Native of dry banks, rocks, and 

 walls in Britain and Europe generally. Suitable alike for rock- 

 work and beds and borders in light dry soil, and for clothing 

 gravelly stony banks. 



S. albo-roseum ( White-and-rose Sto?iecrop). — This plant grows 

 about 18 inches high, with leafy upright stems. The leaves 

 are broad oblong, widening upwards. Flowers in large ter- 

 minal corymbs, white and rose, appearing in summer. Native 

 of Japan. An excellent ornament of the mixed border, flour- 

 ishing in ordinary garden-soil. 



S. Anacampseros {Evergreen Stojieerop). — A very distinct 

 species, with numerous decumbent or creeping stem.s ; the 

 barren ones are crowded with wedge-shaped glaucous leaves in 

 conical rosettes. Flower-stems nearly erect, somewhat leafy.
