These strong growers are related to forget-me-not (Myosotis) but are larger and showier. Their vibrant blue flowers appear from late spring through summer. Alkanets—sometimes called buglosses—are also easy to grow: plant them in well-drained soil and cut back spent flowers for a second bloom. High humidity inhibits growth.Anchusa capensis
Native to South Africa, where it grows in disturbed areas such as along roads. Grows to 1 1/2 ft. tall and about 8 in. wide with narrow leaves.

Bees love them. Plant in well-drained soil. Pretty with white or lavender African daisy (Osteospermum).
