False bindweeds are annual or herbaceous perennial vines in the genus Calystegia, in the Morning Glory family Convolvulaceae. False bindweeds bear much similarity to a related genus Convolvulus, or true bindweeds, and are sometimes mistaken for them.
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.
Species
There are about 25 species, most of them native to tropical or temperate regions.
The name is derived from two Greek words kalux, "cup," and stegos, "a covering," meaning "a covering cup". The stem is creeping over the ground, not winding or hardly winding. The leaves are darkgreen and reniform. The petioles are ovate or elleptical. The coralla is pink or pale purplish, with 5 white stripes.
