Perennial, erect, low shrub (less than 1 m tall), white and woolly, strongly aromatic, and much-branched from a woody rootstock, with older stems becoming woody. Leaves are small (10 × 3 mm), thick, alternate, shallowly dentate, mucronate, and densely hairy, with slightly undulate margins. Numerous flowering branches bear fragrant, small yellow flowers arranged in capitula without ray florets, aggregated into short, dense corymbs on peduncles (1–4 mm) that remain erect at maturity. Bracts and corolla are often coated with golden-yellow resin. The fruit is a glabrous, compressed achene (2 mm long), narrowed at the base.
