Acacia parramattensis
Also called Sydney Green Wattle, Parramatta Green Wattle, Parramatta Wattle
Acacia parramattensis, the South Wales wattle, is a fast-growing tall shrub or tree native to New South Wales, Australia, with feathery bipinnate foliage and yellow summer flowers. It adapts readily to cultivation and is used in revegetation, and it grows best in open, sunny spots with well-drained, moderately fertile soil.
Acacia parramattensis, commonly known as Parramatta wattle, is a tree of the family Fabaceae native to the Blue Mountains and surrounding regions of New South Wales. It is a tall shrub or tree to about 15 m (49 ft) in height with phyllodes (flattened leaf stalks) instead of true leaves. These are finely divided bipinnate . The yellow flowers appear over summer. It generally grows in woodland or dry sclerophyll forest on alluvial or shale-based soils, generally with some clay content.
A fast-growing plant, it regenerates after bushfire by seed or suckering and can quickly colonise disturbed areas. Likewise it adapts readily to cultivation and is used in revegetation projects.
Acacia parramattensis is not commonly seen in cultivation though is grown locally in Sydney and the Blue Mountains. Fast growing and adaptable, it grows 6 to 8 m (20 to 26 ft) high over five years. It can provide shade in the garden, though is vulnerable to being infested by borers. It is propagated by seed.
Fieldwork conducted in the Southern Highlands found that the presence of bipinnate wattles (either as understory or tree) was related to reduced numbers of noisy miners, an aggressive species of bird that drives off small birds from gardens and bushland, and hence recommended the use of these plants in establishing green corridors and revegetation projects.
Acacia parramattensis is found in the Sydney Basin and Blue Mountains in central New South Wales, north to Yengo National Park, west to Grenfell and south to Tumut, from sea level to elevations of 900 metres (3,000 ft). A component of dry sclerophyll forest or woodland, it is found in association with such trees as forest red gum (Eucalyptus tereticornis), Sydney blue gum (E. saligna), mountain white gum (E. dalrympleana), rough-barked apple (Angophora floribunda), turpentine (Syncarpia glomulifera), or in drier locations with gossamer wattle (Acacia floribunda), coast myall (A. binervia), or early green wattle (A. decurrens). A. parramattensis is also a component of the rare and fragmented Southern Highlands Shale Woodlands community.
