Acacia heterochroa is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
The glabrous spreading shrub typically grows to a height of 0.3 to 2.0 metres (1 to 7 ft). [1] It has terete and ribbed branchlets that are dusted in a white powder. The new shoot tend to be a reddish colour with stipules that are easily detached. The grey-green phyllodes have an elliptic to ovate or sometimes almost circular shape with a length of 1 to 3.5 cm (0.39 to 1.38 in) and a width of 1 to 2.5 cm (0.39 to 0.98 in) with a prominent midrib and marginal nerves. [2] It produces yellow flowers from April to December. [1] The simple inflorescences have large spherical flower-heads containing 5 to 12 loosely packed bright lemon yellow flowers. The linear to curved and erect seed pods that form after flowering have a length of up to 6.5 cm (2.6 in) and a width of 3 to 4 mm (0.12 to 0.16 in). The purplish-red pods are thick and woody and dry to a black colour. The glossy brown seeds within the pods have an oblong shape and are 3.5 to 4 mm (0.14 to 0.16 in) in length. [2]
