Orange Clock Vine Overview

Thunbergia gregorii is a fast-growing tender evergreen perennial vine that will scramble its way up a support. It produces salver-shaped rich orange flowers and has triangular-ovate leaves produced on winged stalks. The showy tubular flowers bloom from summer into autumn when grown as annuals in temperate areas (nearly all year round in tropical locations). Thunbergia gregorii is a welcome addition to sheltered patios and mixed flower borders - when planted out after the frosts. Otherwise, it is best grown as a conservatory plant, where it prefers bright filtered light and shade from the hot sun. It likes moist, well-draining soil. Commonly known as Orange Clock Vine, this species has earned a Royal Horticultural Society Award of Garden Merit.
