Blue flowers resembling morning glory. Several of the best-known Thunbergia species are climbers, but this native of tropical Africa is a sprawling shrub, very useful in mixed beds or as a low hedge. It has attractive, small, dark green leaves and tubular flowers which in the most common form are rich purple with a yellow throat; there is also a white-flowering form, which seems to have smaller leaves and is somewhat less robust
The violet-blue, yellow-throated, tubular flowers attract hummingbirds and butterflies.
Grow this tender shrub in full to partial sun and moist, fertile, well-drained soil. It does poorly in alkaline or sandy sites.
T. Erecta also known as 'King's Mantle' responds well to regular pruning and can be shaped into a very bushy shrub, though this inhibits blooming.
Bush Clockvine works well in a mixed border or foundation planting, or as an informal hedge..
Plants with thin leaves need daily watering and ones with thick leaves need watering 3-4 times a week. This will also depend on the season. Generally during the blooming period, plants love a lot of water. Try keeping the soil moist. During winters it is better to cut back on watering.
Keep the plants in a well drained soil with a drainage hole at the bottom. This will help to avoid over watering. Take care as to not leave stagnant water on top of the soil. Fertilise the plant once in 2-3 weeks during its blooming period. Do not fertilise it in winters.
