| 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. |
