The flowers are borne singly on the ends of the branchlets, each flower on a pedicel 2–4 mm (0.079–0.157 in) long. There are broadly egg-shaped sepals about 3 mm (0.12 in) long and five broadly elliptical, pale yellowish green petals about 10 mm (0.39 in) long. The ten stamens are hairy and fused together in the lower part. Flowering occurs from May to September. [2] [3]
