Convolvulus is a genus of about 250 species of flowering plants in the bindweed family Convolvulaceae, with a cosmopolitan distribution. Common names include bindweed and morning glory, both names shared with other closely related genera. They are annual or perennial herbaceous vines and (a few species) woody shrubs, growing to 0.3-3 m tall. The leaves are spirally arranged, and the flowers trumpet-shaped, mostly white or pink, but blue, violet, purple or yellow in some species. Many of the species are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers. However, some other species are globally threatened.
