This vine is native to India and is available in shades of blue, white and lavender. It can be grown in a container but can cover fences or trellis very well.
Botanical Name - Thunbergia grandiflora
Common Name - Bengal clock vine, blue trumpet vine
Also known as Bengal Clock Vine, this plant attributes this odd name to the fact that it entwines itself in a clockwise fashion!
Thunbergia grandiflora requires direct sunlight and so you should plant it after the winter or after the danger of frost is over. Tease and pull the plant through fences if you want it to climb. Keep the area where it is planted, moist.
It doesn’t require fertilizers except in the poorest types of soil. Cut old flowers to have more blooms for longer periods.
