The genus Acrodon is restricted to a swath along the southeast and southern coast of the Western and Eastern Cape Provinces of South Africa. The plants are characterized by three-sided leaves with small teeth growing in rows along the edges and keels as well as their solitary flowers, the petals of which can be striped. They grow in tufts or form small mats. The plants are popular and were first introduced into cultivation in Europe at the end of the 18th century. Acordon are very hardy, but like frequent watering and an acidy, sandy soil. They are easily propagated by seed.
