Thunbergia alata Care

In the past they have been regarded as a conservatory plant where they could be kept going almost all year round. Today they are used as annuals, planted out as soon as the frosts are over.

A sunny position in the garden, in a hanging basket, or in a container with a growing frame of some sort. They will need something to climb on, so a frame around 1 - 2 m tall will suit. In hanging baskets, let them climb up and them cascade down, you can always prune away any growth that is to long.

Best grown from seed planted in spring, keep moist and well fertilised and provide some support for the climbing habit and allow it to scramble up 1m or so.
