In autumn, it bears delicate funnel-shaped violet flowers in an eye-catching spike formation. Care: Best grown in part or full shade for optimum leaf color and growth. Needing very little care, it is drought-tolerant, heat-loving, and relatively pest-free. Not hardy beyond Zone 10, so it may be cut back hard in late fall, potted up, and brought inside. Propagation: Root basal or softwood cuttings in spring or early summer. Cuttings root easily in moist sand. Problems: Sometimes affected by root rot and spider mites. Overview Height 1 ft. to 3 ft.
