Bengal clockvine (Thunbergia grandiflora), also known as sky vine or blue trumpet vine, is a woody, perennial climbing plant that is native to Southeast Asia. It is a popular ornamental plant in many tropical and subtropical regions of the world due to its striking blue-purple flowers and fast-growing, vigorous vines.
