Originating from South Africa, Thunbergia alata is a very attractive evergreen vine that climbs on just about anything that will support it. The twining stems will reach 6-8′ and are covered with triangular-shaped leaves. Showy bright orange flowers appear almost year-round but are most prominent in summer through fall. Thunbergia is a fast grower and light pruning encourages more blossoms to flourish. This beautiful vine can densely cover a vertical area with a contrasting field of green foliage and cheerfully bright flowers. It performs best in full sun and will tolerate some shade. It likes regular watering and rich, moist soil.
