Description and Ethnobotany
| Growth Form | Small to medium-sized tree, with dense bushy, oval to conical-rounded crown, usually 4 - 25 m height. |
|---|---|
| Foliage | Mature leaves dark green and leathery; young leaves coppery-red. Stipules present in leaf axils. Tree is relatively evergreen in wet tropical regions like Singapore, but semi-deciduous in monsoonal areas, where seasonal young foliar flushes are more extensive and pronounced. |
| Flowers | Tree blooms a few times per year, producing erect terminal panicle-inflorescences up to 50cm in height. Individual flowers (3 cm across) have ribbed scruffy-brown calyxes (fused sepals) and flower buds. Velvety crinkled petals fade from rich mauve to pale pink to creamy-white with age, making tree appear to produce flowers of different colours all over the crown. |
| Fruit | Small oblong dehiscent woody capsules borne on branched infructescences, maturing from green to brown, before splitting to disperse abundant small dark brown seeds. |
| Others - Plant Morphology | Bark: Flakes off in plates to reveal greyish-cream-brown patches. |
| Habitat | Open secondary tropical and monsoon riverine gallery forests. |
| Cultivation | Prefers well-drained, humus-rich soils with ample moisture. Extreme drought stress may cause leaf-burn and inhibit blooming. Best to grow at wind-sheltered sunny sites, as shaded moist leaves may be prone to powdery mildew. Propagate by seeds or stem cuttings. Seeds have short viability, so sow as fresh as possible. Rooting hormone can be used to promote the otherwise difficult striking of stem cuttings. |
| Etymology | Genus epithet 'Lagerstroemia' named by Linnaeus (father of modern taxonomy) in honour of his friend Magnus von Lagerstroem (1691-1759), a Swedish merchant (and director of the Swedish East Indies Company), as well as avid naturalist who sent collected specimens of a related species, Lagerstroemia indica to Linnaeus. Species epithet 'floribunda' means 'producing many flowers', a reference to the profuse infloresences. |
| Ethnobotanical Uses | Others: Medicinal: Used to treat fever and myalgia. Regional Myth: Corpse of the last shaman (magician) in Perak, Malaya was disposed of by being placed amongst the branches of a Lagerstroemia floribunda tree between 1870 and 1875, and legend relates that he became a tiger with a white patch. |
