General Description:

The plant family Ericaceae (heaths and heathers) is widespread in many parts of the globe, particularly Europe and South Africa. It contains a number of widely cultivated plants such as Erica, Rhododendron and Pieris.

Like most of Australia’s members of the Ericaceae, Cosmelia belongs to the subfamily Epacridoideae, which was formerly classified as a separate family, the Epacridaceae. Cosmelia is a monotypic genus – comprising just a single species. 

Cosmelia rubra is an erect or spreading shrub, usually growing to about 1 meter in height but occasionally taller. It has simple, linear to narrowly elliptic leaves which are often dark green above and lighter beneath.  The leaves are crowded along the stems, about 20 mm long with entire margins and taper to a sharp point.  The narrow, tubular flowers are deep pink to red and about 25 mm long, tapering towards the end.  They occur singly or in small clusters in leaf axils.  Flowers occur mainly in summer.

The species is a small, ornamental, shrub with a compact habit. Though not widely cultivated, it holds potential as a feature plant particularly in climates similar to its native habitat in southwestern Australia. Although occurring in swampy areas in nature, it should be given a well drained position in sun or partial shade and should not be allowed to dry out. It is also a very attractive plant for a container.  Plants may be damaged in frost-prone areas.

Propagation is usually by cuttings of firm current season’s growth. Like most epacrids, the roots are very fine and easily damaged during transplanting. Cuttings are probably best placed into individual small pots or tubes to minimise root disturbance. The species can also be grown from seed.
