DIASCIA

South African natives related to snapdragon (Antirrhinum). The coral to purplish pink flowers each have two prominent spurs on the back; these bear oils attractive to pollinating bees. Blooms are carried in spike-like clusters at stem ends from spring through early summer and often into fall. At their best used in rock gardens, borders, or containers. With the exception of Diascia barberae, all of the species listed here are perennial, though these perennials may die in winter if planted in heavy, wet soil. Shear back after bloom period.
