Acacia applanata, commonly known as grass wattle,[2] is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia.

It is an erect, grass-like shrub or subshrub with only a few phyllodes, continuous with the branchlets, and up to 4 racemes of spherical heads of 10 to 20, usually golden flowers, and curved, crust-like pods up to 30 mm (1.2 in) long.

Acacia applanata is an erect or sometimes sprawling, grass-like shrub or subshrub that typically grows to a height of 10–50 mm (0.39–1.97 in) and sometimes has weak, prostrate stems, sometimes spreading by underground suckers.

[2] This species of Acacia grows in open woodland, woodland or forest in sand, loam or laterite, often in winter-wet depressions from near Jurien Bay to Albany, Western Australia in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.

[2][3][4][5] Grass wattle is a hardy shrub in well-drained soil, with part to full sun.
