Melaleuca osullivanii is a shrub in the myrtle family, endemic to south-west Western Australia, growing to about 3 m with narrow leaves and creamy white flowers. It is a wild broombush species with little horticultural use, so care is mostly inferred from its native sandy, seasonally wet coastal habitat.

About

Melaleuca osullivanii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It was first formally described in 2004 after a review of the broombush group, Melaleuca uncinata. It differs from others in the group by having leaves that are fine and circular in cross section. The closest other broombrush is Melaleuca hamata whose leaves are 0.8–1.6 mm (0.03–0.06 in) in diameter compared to 0.7–0.9 mm (0.03–0.04 in) for this species.

Where it grows

This melaleuca occurs in and between the Perth, and Busselton districts in the Jarrah Forest and Swan Coastal Plain biogeographic regions. It often grows in sand in association with other heathy species of Melaleuca, Hakea, Grevillea and introduced grasses in areas close to the coast that are wet in winter.
