About
Myoporum montanum, commonly known as waterbush or boobialla, is a shrub native to Australia, New Guinea and Timor. The species is extremely variable in size growth habit and leaf form, with three primary forms recognised. Its occurrence in many places is restricted to coastal regions, watercourses and other locales with more reliable water supplies. It was this association with water that gave rise to the name water bush.
How to grow it
Waterbush is a hardy plant in cultivation and can tolerate drought. It is a useful screen plant in drier places and is readily propagated from cuttings.
Where it grows
Waterbush occurs in all mainland states of Australia. It occurs in scattered areas in New Guinea and Irian Jaya and there is one record from Timor. It is very common in eastern Queensland, New South Wales and eastern South Australia. It grows in a wide variety of ecosystem types, from mangrove swamps to rainforest to the Simpson Desert on a wide range of soils. Occurrences throughout the rest of the continent, New Guinea and Timor are largely restricted to coastal regions, watercourses and other locales with more reliable water supplies.
