Guichenotia sarotes is a spindly, low-growing shrub that typically grows to high and wide, its new growth densely covered with star-shaped hairs. Its leaves are greyish, linear to lance-shaped, long, wide and
sessile with narrowly egg-shaped
stipules long at the base of the leaves. The edges of the leaves are rolled under and both surfaces are covered with white, star-shaped hairs. The flowers are blue-mauve, pink, or white and arranged in
cymes of two to six on a
peduncle long, each flower on a
pedicel long with an egg-shaped
bracteole at the base. The five petal-like
sepals are long and hairy, and there are tiny, dark red petals but no
staminodes. Flowering occurs from July to November. ==Taxonomy and naming==
