Centradenia is a small genus of 4–5 species of tropical evergreen perennials and subshrubs in the family Melastomataceae (order Myrtales), native to Central America and Mexico. Plants typically form bushy mounds with distinctively angled or winged stems that are often tinted in shades of red or bronze. The opposite leaves are lanceolate to ovate, simple, pointed, with well-defined veining and a somewhat velvety texture; the undersides are frequently flushed deep red, providing ornamental value even when the plant is not in bloom. Flowers are small, 4-petalled, pink to mauve or occasionally white, with 8 stamens and a 4-lobed calyx, carried in terminal or axillary panicles. Blooming typically occurs in winter, making Centradenia particularly valued in subtropical gardens during the cooler months. The genus is closely related to other members of Melastomataceae such as Tibouchina and Heterocentron, sharing the family's characteristic free stamens and inferior ovary.
Distribution
Centradenia is native to Central America and Mexico, where species grow in tropical and subtropical habitats. The genus is restricted to the Neotropics and is not naturally found outside this region.
Cultivation
Centradenia plants are showy additions to subtropical and tropical gardens, valued for their winter flower display. They perform best in rich, humus-rich soil with sharp drainage and prefer partial shade with good light. Established plants respond well to liquid fertiliser, which intensifies both flower and foliage color. Propagation is straightforward from seed or stem cuttings.
