plants. They may be increased by divi- 

 ding the rootstoeks or by sowing seeds in 

 spring in the case of the single-flowered 

 kinds. The double-flowered varieties are 

 best increased by division, as they do not 

 usually seed so freely as the single ones, 

 and also because seedlings rarely come 

 with the true characters of the parent 

 plants. 



The Double Potentillas are by far 

 more beautiful garden plants than the 

 natural species. Grown in a light deep soil 

 with plenty of sun they make glowing 

 pictures in the flower garden from June to 

 September. Although the flowers are 

 more or less double, and resemble small 

 Eoses, they ripen some seeds, and from 

 these new forms may be obtained by those 

 in search of novelties. 



These double-fiowered forms are the 

 result of crossing the atrosanguinea form 

 of P. argyrophylla with forms of P. 

 nepalensis, and it is remarkable that 

 these Himalayan species have produced 

 such a fine hardy race of ornamental 

 flowers.
