Westringia rigida is a shrub, growing from 30 to 60 cm high, and has stiff and often tangled branches. The sessile leaves generally occur in whorls of three. The leaf blades are from 1.9 to 5.2 mm long by 1 to 2 mm wide, with entire margins and recurved to revolute,and both upper and lower surfaces are sparsely to densely hairy.[7]

The bracteoles are 1 to 1.5 mm long. The outer surface of the green calyx is densely hairy. The corolla is 6 to 7 mm long, and is white, frequently with a mauve tinge, and orange to orange-brown dots.[7]
