Common periwinkle is a vine or subshrub in the dogbane family (Apocynaceae) that is native to Europe and was introduced for ornamental purposes many decades ago. It occurs throughout the United States in at least 36 states, has escaped cultivation and is invading natural areas. Common periwinkle poses a threat to native plants and communities because it grows vigorously, forming a dense monotypic evergreen groundcover that displaces and excludes most other plants, including native wildflowers. It spreads by vegetative means only. Flower color can be blue, lilac or white. Several close relatives of this plant, including bigleaf periwinkle (Vinca major), imported from Europe, and Madagascar periwinkle (Catharanthus roseus), native only to Madagascar, are also invasive in natural areas in the mid-Atlantic and other regions of the United States and the world.
