Calystegia
Also called False Bindweed, Bindweeds, False Bindweeds
Calystegia (bindweed, false bindweed, or morning glory) is a formerly accepted genus of flowering plants in the family Convolvulaceae. In 2025, a taxonomic study proposed merging the genus into the closely related Convolvulus, a treatment also followed by the Plants of the World Online (POWO) taxonomic database, which recognises Calystegia as a synonym of Convolvulus. The genus has a cosmopolitan distribution in temperate and subtropical regions, but with half of the species endemic to California.
Some of the species, notably Calystegia sepium and C. silvatica, are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers.
