* Cult. C. tomentisum, grandiflorum, and Dahiricum, are the 
only species of this genus worth cultivating as border flowers. 
C. latifdlium, C. alpinum, and C. glaciale, are well adapted for 
rock-work, or to be grown in small pots, in a mixture of loam, 
sand, and peat ; the rest are only worth preserving in general 
collections. They only require the treatment of other hardy 
plants. The perennial species are increased by dividing the 
plants at the roots. The annual and biennial species by seeds, 
which should be sown in the open ground in the spring.
