Thunbergia alata Orange, Pink, Yellow, Colorado Glow is a hardy, evergreen, twining climber that has attractive, bright-green, heart-shaped leaves.

Throughout the year, but particularly in summer and autumn, it produces masses of orange, pink, yellow or 'colorado glow' trumpet-shaped flowers with a dark, purple-brown tube. These flowers attract tiny insects to the garden. Both pink and yellow forms of this plant are available.

This useful plant can be used as a groundcover, to cover a fence, climb a trellis, to tumble over a terraced wall or out of a hanging basket. When in flower this is an exceptionally attractive plant for semi-shade or shady areas.

Prune back quite hard once a year to encourage flowering.

It is fast-growing and requires well-drained soil and only moderate water.

Size: 1 to 4 meters or as tall as the support.
