Care of the plant Thunbergia grandiflora or Blue trumpet vine

The genus Thunbergia, family Acanthaceae, comprises 150 species of flowering plants native to tropical regions of Asia, Africa, and Madagascar. Some species are: Thunbergia grandiflora, Thunbergia alata, Thunbergia fragrans, Thunbergia erecta, Thunbergia mysorensis.

Common names: Blue thunbergia, Blue trumpet vine, Skyflower, Bengal trumpet, Skyvine. This species is native to China, India, Nepal, Indochina and Burma.

They are perennial climbing plants with large leaves (15-20 cm) opposite lanceolate or oval. The showy flowers appear in clusters, have large trumpeted corollas and bloom for several months (summer and fall).

These plants are ideal to use covering walls, fences and pergolas. They need supports to climb.

Thunbergia grandiflora needs semi-shade or full sun exposure. They do not resist frost.

The soil can be a mixture of coarse sand, leaf mulch, and manure.

Water regularly so that the soil does not dry out completely (never water); reduce watering considerably in winter.

They are quite resistant plants to pests and diseases.

They are propagated by cuttings or by seeds in spring.
