Summary

Thunbergia erecta, commonly known as Bush Clockvine, is an evergreen perennial that can be trained as a vine or grown as a shrub. It is native to the tropical rainforests of Central and Western Africa, where it thrives under the canopy of larger trees. This species typically reaches a height of 4-6 feet (1.2-1.8 meters) and a width of 5-8 feet (1.5-2.4 meters). The Bush Clockvine has dark green, ovate leaves and produces tubular flowers that are most commonly blue to purple, with a pale yellow or white throat, blooming profusely in the summer and fall. The flowers are notably showy and attract pollinators such as butterflies and hummingbirds.

Bush Clockvine is valued for its ornamental flowers and its ability to cover trellises and fences, making it a popular choice for vertical interest in tropical and subtropical gardens. It can also be used as a ground cover or container plant. This plant prefers a warm climate and does best in full sun to part shade. It requires medium amounts of water and well-drained soil to prevent root rot. While it is relatively low-maintenance, it may need regular pruning to keep its growth in check and to maintain a desirable shape. It is not typically prone to serious pest or disease problems, but spider mites and whiteflies can occasionally be an issue in hot, dry conditions.CC BY-SA 4.0
