Cult. These pretty little plants are well adapted for rock- 
work or to be grown in small pots (well drained with potsherds) 
and placed among other alpine plants. The annual and biennial 
species should all be sown on rock-work or in a dry situation in 
autumn or early in spring, or they may be allowed to scatter 
themselves, which is the best mode. The perennial kinds, which 
are recommended to be grown in pots, or on rock-work, do best 
in a mixture of loam, sand, and peat. They may be either in- 
creased by dividing the plants’ at the root or by seeds, which 
ripen in plenty, or cuttings will root freely, planted under a 
hand-glass.
