Description and Ethnobotany
| Growth Form | Evergreen vine or shrub with a twining growth habit, up to 7 m in length. |
|---|---|
| Foliage | Smooth, dark green glossy leaves are elliptic with entire leaf margin, measuring up to 15 cm long and 7 cm wide. Leaves are deeply veined and have a long pointed tip (acuminate apex). Leaf base is obtuse or rounded. Leaves are arranged oppositely along the stem. |
| Stems | Woody, quadrangular, puberulent (hairy). |
| Flowers | Flowers are composed of 4 white, ovate calyces and 5 dark red, obovate petals and 5 white, long stamens. The calyces form a pyramidal shape with the tips hanging downwards. |
| Fruit | Fruits are drupe-like, black. Seeds oblong. |
| Habitat | Found in disturbed areas, wet lower montane forests and weedy flats. It is mostly planted as ornamental in cultivated areas. |
| Cultivation | Plant in slightly acidic to neutral, well-drained soil with 0.5 - 0.6 m of space between individuals. The soil should be kept moist, but not soggy. This species grows best in a humid environment. Generously feed with a fertilizer containing micronutrients. A slow-release fertilizer can be applied bimonthly or a liquid soluble fertilizer monthly. Adequate calcium is required for optimal flowering and may be added to the soil mix as crushed egg shells. Propagate by woody stem cuttings or suckers. |
| Etymology | The genus Clerodendrum comes from Greek word meaning chance-tree. The specific epithet thomsoniae is named in honour of Thomas Thomson, a Scottish doctor who was superintendent of the Calcutta Botanic Garden. |
