'''''Thunbergia''''' is a [[genus]] of [[flowering plant]]s in the [[family (biology)|Family]] [[Acanthaceae]], native to tropical regions of [[Africa]], [[Madagascar]] and southern [[Asia]]. Its members are known by various names, including '''thunbergias'''; '''clockvine''' 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 (disambiguation)|Black-eyed Susan]]). Orange clockvine is the name of ''Thunbergia gregorii''.
Thunbergia was named for [[Carl Peter Thunberg]].
Thunbergias are vigorous annual or perennial [[vine]]s and [[shrub]]s growing to 2-8 m tall.
Some are frequent garden escapes, becoming [[invasive species]]; they are regarded as environmental threats in [[Australia]], for example.
