This is one of the many pea flower genera from the legume Fabaceae family, which now also includes Acacia, Senna etc. Jacksonia venosa is a small shrub mostly between 10-20 cm (4-8") in height spreading to 60 cm (2') diameter. It is very common in Western Australia in near coastal locations from Ravensthorpe to Israelite Bay, with Esperance centrally placed between.
Although there are several similar looking Jacksonia plants in the district, J. venosa is easily distinguished by their relatively near coastal distribution and the flowers, which are strongly veined red on the back of the standard. It normally grows in a heath environment on a variety of non-calcareous sand and/or gravel soils. The flowers are invariably yellow and orange, merging to red.
Several Jacksonia spp. are very opportunistic regarding unseasonal rainfall, by quickly coming into flower to take advantage of a good soaking, so often flowers can be found during a wet summer, although not as numerous then as from August to October, which is their main flowering period.
