It is an erect, woody shrub or small tree with pinnate leaves and up to fifteen pink to white four-petalled flowers arranged in leaf axils in spring and summer.

The flowers are arranged in groups of up to fifteen in leaf axils on a peduncle 4–15 mm (0.16–0.59 in) long.

The four petals are pale to deep pink or white and 4.5–7.5 mm (0.18–0.30 in) long and the eight stamens are hairy.
