Homalocalyx is a small genus of about 11 species including all species previously included in Wehlia. They are small shrubs similar to Calytrix. All are endemic to Australia and most are found in Western Australia.
Homalocalyx polyandrus was previously known as Wehlia polyandra. It is a small shrub to a metre or so in height by a similar width. The leaves are very small (2-4 mm long by about 1 mm long) and closely packed together. The pink to purple, star-shaped flowers are about 10 mm in diameter, occurring in masses clusters and with numerous long stamens.
H. polyandrus has received only limited cultivation (a situation shared by other members of the genus). It is likely to be best suited to temperate, dry climates in a sunny or semi-shaded position and in well drained soils. It should be tolerant of at least moderate frosts and light pruning to maintain a bushy shape.
Propagation is best from cuttings as seed can be difficult to germinate. Cuttings of firm, current season’s growth should strike reasonably well.
