These slender-stemmed subshrubs and perennials are grown for their opposite, simple, often variegated leaves and their showy, star-like or salverform flowers. They are native to the woodlands of Europe, North Africa, and Central Asia. Vinca is useful as a groundcover in a woodland area, in the shrub border, or on a shady bank. It can be invasive.
Noteworthy CharacteristicsShowy, long-stalked, often blue or white flowers. Some may be invasive. All parts may cause mild stomach upset if ingested.
CareTolerant of most any soil except very dry. Full sun produces the best flowering, but vinca can also be grown in part shade. May be cut back hard in early spring to control growth.
PropagationDivide in early spring or mid- to late autumn, or take semi-ripe cuttings in summer.
ProblemsLeafhoppers, scale insects, aphids, leaf spot, and dieback may attack plants.
