It is an erect, spreading shrub with hairy new growth, linear leaves with the edges rolled under, and pink flowers arranged in groups of three to seven.

There are five pink, petal-like sepals 6–8 mm (0.24–0.31 in) long, tiny, dark red petals and densely hairy staminodes.

Flowering occurs from July to September and the fruit is a papery capsule about 3 mm (0.12 in) in diameter.
