Appearance
Leucophyta brownii is a small, rounded shrub with tangled tomentose branchlets that give it a silvery appearance. Although it can grow up to 1 metre high, it is more usually 0.2 to 0.7 metres high. It produces flowers during summer. These are white - yellow globular heads and about 1cm indiameter.
Naming
The sole species in the genus is Leucophyta brownii, also known as cushion bush. In 1891 German botanist Otto Kuntze assigned a number of species to this genus in his publication 'Revisio Generum Plantarum' but none of his name combinations have currency, these species being presently divided between the genera 'Balladonia', 'Blennospora', 'Calocephalus' and 'Gnephosis'.Habitat
Leucophyta brownii is found in coastal environments. It commonly occurs on the exposed faces of cliffs and dunes on the south coast of Australia. It is highly tolerant of prevailing winds, sea spray, drought and frost and grows on predominantly sand or sandstone derived soil. Further, the soil can be highly alkaline. It grows most successfully in full sun.Uses
The species is common in cultivation in Australia, with a selected dwarf form from Tasmania, known by the cultivar name 'Silver Nugget', also grown.References:
