Thunbergia erecta prefers a sunny site but will tolerate partial shade. It likes a moderately moist soil and will attract butterflies and hummingbirds for its profusion of stunning blue, lavender, and purple flowers. It also has a white or off-white cultivar with smaller leaves . This large shrub is remarkably hardy and can survive temperatures as low as 30F for short periods of time. The plant is recommended for USDA Zones 9-11 and if you live in a colder region can be grown in pots.
For growing healthy Thunbergia erecta provide it with right care. When planted outdoors, keep the soil consistently moist, but not soggy, and use mulch around the base to retain moisture. If growing in a pot, frequent watering is necessary. Avoid overfertilizing as this can lead to foliage growth with fewer flowers. Pruning and shaping can be done at any time, however, be mindful of your pruning as this can affect flowering. In colder climates, winter protection may be necessary.
