 ornamenting rock-work, but the rarer and more tender species 

 should he grown in pots in a mixture of sand, peat, and loam. 

 They are all increased by dividing the plants at the root, or by 

 seeds, which generally ripen in this country, which last is by far 

 the best method. The seeds of the annual kinds only require 

 to be sown in the open border in spring.

 This is an elegant plant. The Siberian plant is more villous
