Keep the soil well watered, especially when young, and during hot and dry weather. If grown in containers, be vigilant that they do not dry out.

Keep young plants well weeded, until they get established and begin to climb.Thunbergia plants can be trimmed, as needed.

Plants need the support of a fence, trellis or post. Train young plants to reach the support.

Thunbergia Alata Special Feature
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, arbours 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.
Thunbergia Alata Uses
Ornamental Use:

  • Trellises, arbors, fences or other structures around the home
  • Also effective in hanging baskets where the vine can twist around the basket supports or in patio containers with a small trellis or obelisk buried in the container
