Acacia guinetii, commonly known as Guinet's wattle, is a shrub of the genus Acacia and the subgenus Pulchellae that is endemic to a small area along the coast of western Australia The evergreen shrub typically grows to a height of 0.3 to 2 metres (1.0 to 6.6 ft)[1] with a width up to about 2.5 m (8 ft 2 in)[2] and has a spindly to spreading habit with villous branchlets that arch downwards.

[1] The rudimentary inflorescences are found on one or two headed racemes and have spherical flower-heads containing 50 to 75 densely packed golden flowers.

[3] The species was first formally described by the botanist Bruce Maslin in 1979 as a part of the work Studies in the genus Acacia (Mimosaceae) - Additional notes on the Series Pulchellae Benth.

[3] The shrub is available commercially and can be planted as a part of a border, rockery or shrubbery and is noted its dense foliage, low spreading habit and the masses of yellow, fluffy spherical flowers it produces in winter and spring.

It is quite fast growing, tolerates full sun and a light frost and drought but requires a well drained soil.
