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.
