It is a sprawling shrub with hairy young stems, lance-shaped to oblong leaves and white to cream-coloured flowers.

Lasiopetalum maxwellii is a sprawling shrub that typically grows to a height of 25–60 cm (9.8–23.6 in) and has hairy stems.

The sepals are cream-coloured or white, 5–6 mm (0.20–0.24 in) long and the petals reduced to small scales or absent.
