Melaleuca is a genus of nearly 300 mostly Australian species, ranging from small shrubs to trees up to 35 m, grown for their bottlebrush-like flowers, dense screens and aromatic foliage. Commonly grown garden members are shrubs and small trees such as the bottlebrush and paperbark types, which prefer full sun and moist to waterlogging-tolerant soil.

About
Melaleuca () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles, bottlebrushes or tea-trees (although the last name is also applied to species of Leptospermum). They range in size from small shrubs that rarely grow to more than 1 m (3 ft 3 in) high, to trees up to 35 m (115 ft). Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers.
Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia.
Where it grows
Most melaleucas occur naturally only on the Australian mainland. Eight occur in Tasmania, but only two are endemic to that island. One (M. howeana) is endemic to Lord Howe Island and seven are endemic to Grande Terre, the main island of New Caledonia. A few tropical species also occur in Papua New Guinea, and the distribution of one subspecies, Melaleuca cajuputi subsp. cumingiana extends as far north as Myanmar, Thailand, and Vietnam. The southwest of Western Australia has the greatest density of species, and in the tropical north of the continent, species such as M. argentea and M. leucadendra are the dominant species over large areas.
