Special Features
Used mainly as an ornamental plant, Thunbergia alata makes a good screen when used to cover unsightly dead trees or walls. It needs some support, as it cannot cling. Use fences, trellises, arches, arbors, and pillars, or a lightly shading tree. (Pergolas would probably be too big.) Alternatively, plant this creeper in groups as a ground cover, or on a bank or terraces where it can trail downwards. Hanging baskets are also a possibility.
