Geijera parviflora: is a member of the Rutaceae family in company with citrus, Croweas and Boronias. Wilga is the universally accepted common name.
Geijera parviflora is a small, spreading tree that may reach a height of 10 metres. Plants have spreading crowns and pendulous branches that are often trimmed by sheep. Leaves are between 3-20 centimetres long by about 8 millimetres wide. They are linear to lanceolate, glossy, darkish green above and aromatic when crushed.
Flowers are carried in lage clusters at the ends of branches. They are white, with five petals, about four millimetres across, with a strong smell and appear between June and November. Sporadic flowering may occur at other times. The blooms are followed by globular fruits that contain a glossy black seed.
Wilgas, with their spreading crowns, are probably too large for average suburban gardens but come into their own on farms, parks and roadside planting. Wilgas are valuable trees as they provide shade and shelter for farm animals as well as people.
Geijera parviflora occurs in inland areas from Queensland through New South Wales, Victoria to South Australia.
The Australian Willow is the name given to a cultivated form that is grown in the USA. Wilga is also grown as a greenhouse specimen in England.
Propagate from seed or cuttings. Both propagation methods are a trifle difficult. Best results are obtained using fresh seed.
