About Acacia iteaphylla F.Muell. ex Benth.
Scientific name: Acacia iteaphylla F.Muell. ex Benth.
Description: This shrub has a weeping growth habit, typically reaching 2 to 5 metres (6.6 to 16.4 ft) in height, with a crown width of 2 to 5 m (6.6 to 16.4 ft). Young plants are glabrous, with greenish bark that turns brown as the plant matures. Its slender grey-green foliage has pink-red new growth tips. The long, slender phyllodes are arranged alternately, feature a single prominent lengthwise vein, and grow up to 10 centimetres (3.9 in) long. It produces yellow flowers between March and September. Flowers are arranged in small spherical clusters that form short compound clusters in the forks of phyllodes. Flower heads are 5 to 8 millimetres (0.197 to 0.315 in) in diameter, and hold 12 to 17 pale to lemon yellow flowers. After flowering, thin, leathery, light brown elongated flat seed pods form; pods are usually 5 to 13 centimetres (2.0 to 5.1 in) long and 6 to 12 mm (0.236 to 0.472 in) wide. Pods contain hard black ellipsoidal seeds that measure 6 mm (0.236 in) long, with half that measurement in width.
Distribution: It is native to the Flinders Range, Gawler Range, and Eyre Peninsula of South Australia. In its native range, it grows on hillsides among rocky outcrops, or along rocky creek beds. This shrub is now also found in parts of New South Wales and western Victoria, where it is classified as an invasive species. It is also invasive and naturalised in Western Australia. It has a sporadic distribution across the South West, Wheatbelt, and Great Southern regions of Western Australia, where it grows in sandy soils within jarrah forest.
Cultivation: This shrub is sold commercially for cultivation as seedlings and in seed form. It tolerates both full sun and partial shade, grows well in saline soils, and is both frost tolerant and drought tolerant once established. It is used in gardens as an ornamental screen or low windbreak, due to its fast growth rate and attractive foliage. The best known cultivar of A. iteaphylla is a low-growing form called Acacia "Parsons Cascade". Seeds require scarification or treatment with boiling water before planting.
