Thunbergia battiscombei

Description

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.
