Cult. The perennial herbaceous and sub-shrubby species of this 
genus answer well for the flower-border in any common garden 
soil; some of the smaller kind do well for ornamenting rọck-work, 
or to be grown in pots, and placed among other alpine plants; they 
may be either increased by cuttings planted under a hand-glass, 
by seeds or by dividing the plants at the root. The biennial 
and annual kinds may all be sown in the open ground, and 
treated as other hardy annuals and biennials.
