Thunbergia is a genus of flowering plants in the family Acanthaceae, native to tropical regions of Africa, Madagascar and southern Asia. Thunbergia species are vigorous annual or perennial vines and shrubs growing to 2–8 m tall. The generic name honours the Swedish naturalist Carl Peter Thunberg (1743-1828).

Its members are known by various names, including thunbergias and clockvine. Thunbergia on its own usually refers to Thunbergia grandiflora , while Thunbergia alata is often known as black-eyed Susan vine or just black-eyed Susan (not to be confused with other flowers called black-eyed Susan). Orange clockvine is the name of Thunbergia gregorii .

Thunbergias are frequent garden escapes, becoming invasive species; T. grandiflora, T. fragrans, and T. laurifolia are considered weeds in Australia. [2]
