[4] It is found in locations exposed to coastal winds, red-eyed wattle grows as a dense, dome shaped shrub; this helps protect against salt spray, sand-blast and erosion of soil at the roots.
Both the common and species names refer to the appearance of the pods when first open in late spring: each shiny black seed is encircled by a thick orange-red stalk, resembling a bloodshot eye.
The species was first formally described by the botanist George Don in 1832 in the work A General History of Dichlamydeous Plants.
It was reclassified as Racosperma eglandulosum in 2003 by Leslie Pedley and transferred back to the genus Acacia in 2006.
[2] In South Australia it is also found to have a discontinuous distribution from the border eastwards to around Yorketown and Yorke Peninsula and on Kangaroo Island.
The species was introduced in the 1830s where it was used as a dune stabiliser and by 1975 it occupied around 300,000 ha (740,000 acres) of coastal lowlands, and sandy river valleys of inland areas forming dense thickets.
The seeds pods are also crushed while still green to make an insect repellent and sunscreen that is also used to treat eczema.
