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 (20 cm/7.87") opposite lanceolate or oval. The showy flowers appear in clusters, have large trumpeted corollas and bloom for several months (summer and fall). This plant is ideal to use covering walls, fences and pergolas. Blue trumpet vine needs supports to climb. Thunbergia grandiflora needs semi-shade or full sun exposure. It does 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 flood); reduce watering considerably in winter. Thunbergia grandiflora is a quite resistant plant to pests and diseases. Skyflower is propagated by cuttings or by seeds in spring. |
