Diascia

Diascia - A pretty group of herbs from S. Africa, allied to Alonsoa. The only kind in cultivation is D. Barbara, a neat annual 9 to 12 inches high, with square stems and small wedge-shaped leaves. Raised in heat in spring and planted out in May, it flowers until late autumn, the soft coral-pink flowers with two spurs. Though mostly treated as a half-hardy annual, the roots are perennial in the warm soils of southern gardens, spreading by stolons into handsome tufts. Seeds.
