Acacia cyclops, commonly known as coastal wattle, cyclops wattle, one-eyed wattle, red-eyed wattle, redwreath acacia, western coastal wattle, rooikrans, rooikans acacia, is a coastal shrub or small tree in the family Fabaceae. Native to Australia, it is distributed along the west coast of Western Australia as far north as Jurien Bay, and along the south coast into South Australia.
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. When sheltered from the wind, it tends to grow as a small tree typically to a height of 0.8 to 4 m (2 ft 7 in to 13 ft 1 in) but can reach as high as 8 m (26 ft). Like many other Acacia species, red-eyed wattle has phyllodes rather than true leaves. The phyllodes range from four to eight centimetres long, and from six to twelve millimetres wide. Its flower heads are bright yellow spherical clusters. Very few flower heads are produced at a time, but flowering occurs over a long period, from early spring to late summer, between September and May. This is unusual for Acacia species, which normally flower in one brief but impressive display.
