Melaleuca quinquenervia is a serious woody weed of wetland habitats in Florida and Louisiana. Mechanical control has not been successful and research in recent years has been focused upon biological control.

Melaleuca viminalis is well known in cultivation and is widely grown for its showy flowers. The species is an unusual member of the bottlebrush group of Melaleuca in that its staminal filaments are connate into five bundles; most other species of bottlebrush have distinct stamens.
