About
Thunbergia gregorii, commonly known as orange clockvine or orange trumpet vine, is a herbaceous perennial climbing plant species in the family Acanthaceae, native to East Africa and sometimes cultivated as an ornamental vine. The bright, pure all-orange flowers distinguish it from the related black-eyed Susan vine (Thunbergia alata).
Spencer Le Marchant Moore described the species in 1894, naming it after John Walter Gregory. Within the genus Thunbergia, it is most closely related to T. alata, the two being placed in the subgenus Parahexacentris. The common name of clockvine relates to the vine spiralling upwards in a clockwise direction.
