Aspalathus is a genus of flowering plants in the legume family, Fabaceae. The yellow flowers and spiny habit of some species have suggested a resemblance to Ulex europaeus, the thorny "English gorse" Accordingly, "Cape Gorse" has been proposed as a common name although the resemblance is largely superficial; for instance, gorse is thorny, whereas Aspalathus species are variously spiny or unarmed. The genus belongs to the sub family Faboideae. There are over 270 species, mainly endemic to southwestern fynbos regions in South Africa, with over fifty occurring on the Cape Peninsula alone. The species Aspalathus linearis is commercially important, being farmed as the source of Rooibos tea.
Aspalathus species generally are shrubs or sometimes shrublets. They typically are bushy, but some species may be sprawling or erect with free-standing branches. The flowers of most species are plentiful in season, a rich, showy yellow very common in the Western Cape mountains in particular. The flowers of some yellow-flowering species (such as Aspalathus cordata) turn bright red as they fade. Some species, such as Aspalathus forbesii have white or cream flowers, and others, such as Aspalathus costulata and Aspalathus cordata have flowers in various shades ranging from pink to pale violet, whereas Aspalathus nigra commonly has slate-blue flowers.
Aspalathus leaves are sessile and are simple in some species, but trifoliate in others. They commonly are fascicled. In some species they bear hard, sharp, spines at their tips. There are no stipules.
