Free Thunbergia Alata Hybrids PlantsA climbing plant that produces orange to yellow flowers with a dark centre or ‘eye’, hence the common name of Black-eyed Susan. Given the correct care, the Thunbergia will remain in flower from the end ofspring to the beginning of autumn. Dead or dying flowers should be removed before rotting occurs or seeds are set, as either will reduce the flowering period. The plant’s twining stems grow vigorously and can completely cover a screen or trellis in the first season. It can look particularly attractive when trained to grow up strings in front of a window. Although the Thunbergia is a perennial, the growth can become very leggy and straggly, and the plant is often discarded after the first flowering.
