Aizoon (see coloured plate) is a native of the Alps 

 of Europe and America, and one of the best of the 

 encrusted section. It forms tufts of silver grey, which 

 can be divided if propagation is desired. There is no

 on a sunny spot. The following are twelve of the best 

 of the many forms of it which are grown : 



AtropuYpurea. Malyi.

 of the London Pride section, and the encrusted species 

 Aizoon J which is described above. It is a green-leaved 

 species, with large white flowers dotted with red. It 

 enjoys moist soil, and may be propagated by division.
