A global citizen science platform
to discover, share and identify wildlife
Annual or perennial herbaceous vines, bines and (a few species of) 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.
This species occurs in many temperate regions
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.
