Although the specific name means “with white flowers”, it is not uncommon to come across plants of this species with light to dark pink flowers.
They form erect, much-branched shrublets to 15 cm tall, with leaves that are 7-10 mm long and 4 mm thick, round in cross-section, and with a blunt tip.
Between August and November, the plants produce their flowers at the tips of the branches; they are up to 17 mm in diameter.
In certain parts of the distribution area – stretching from Matjiesfontein to Robertson and Riversdale – the plants grow in abundance.
