Most of the aehillcii* can be };ro\vii in ordinary par- 

 don soil, preferring- open sunlight and well-drained 

 situations. Some are alpine or 

 sub-alpine anil require rock- 

 garden conditions. These arc 

 indicated inidcr the individual 

 species. Dwarf kinds make 

 carpets in dry, sininy places; 

 large kinds suitable for wild 

 gardens. 



Propagation in spring by 

 division, cuttings and .seeds; 

 chieHy by the ftrst mc-thoil and 

 easily accomphshed.

ACHIMENES (Greek, cheimaino, to suff'er from 

 cold). Including Scheeria. Gesncrdcese. Greenhouse 

 herbs, allied to gloxinias, native to tropical America,

The gardf^n achimenes are much confused by hy- 

 bridization, and it is doubtful whether any of the pure 

 species are in general cultivation in this coimtry. Years 

 ago, the small red-flowered ty^ies (of the coccinea sec- 

 tion) were frequent, but modern evolution has proceeded 

 from tli(! broad-flowered purple species. The species
