About
Myoporum insulare, commonly known as common boobialla, native juniper, is a species of flowering plant in the figwort family Scrophulariaceae and is endemic to coastal areas of Australia. It is a shrub or small tree which grows on dunes and coastal cliffs, is very salt tolerant and widely used in horticulture.
Where it grows
Myoporum insulare occurs in coastal areas of New South Wales, Victoria, South Australia, Western Australia and Tasmania. In New South Wales it occurs from Eden southward, although an isolated occurrence was recorded much further north on Brush Island. It is also found on Lord Howe Island. In Victoria it is found in coastal areas but also inland in the west of that state. Boobialla is common along the coast of South Australia and in Western Australia it occurs south from Shark Bay to the South Australian border. It grows in sandy soils, often between rocks or near sandstone. Myoporum insulare is invasive in several African countries and in the western coastal areas of the US. Invasive populations may include some other species of this genus. In South Africa this species is known as manatoka.
