Wide-spreading subshrub up to 1 m. Stems much branched, leafy. Stem and leaves with an indumentum of small adpressed dendroid-stellate hairs and numerous sessile oil globules. Leaves narrowly to broadly oblong-lanceolate, acute, crenate - sometimes deeply so - to serrate, c. 3-5 x 0.8-2 cm, tapering into a c. 1.5 cm petiole; upper leaves smaller, often subentire, merging into bracts. The characters of inflorescence, calyx, corolla, stamens and nutlets are not different from Perovskia abrotanoides.
