Leaves of verbena menthifolia
have a pair of lobes near the base, and smaller lobes, or large teeth, higher up. Leaves have a sparse covering of hairs, most noticeably along the margins. The base of the leaves taper to a flat stalk. Leaves have a depressed midvein, and smaller side veins. Plants typically produce one, two or three stems, quite thick, and growing generally upwards.
The inflorescence is long (up to ten inches) and narrow, the flowers well separated. Flowers are small; they have a five-toothed calyx, around 0.1 inch long and a pale, purple-pink corolla of comparable length, opening to five lobes, with bilateral symmetry. The bracts beneath the flowers are ovate to lanceolate, pointed at the apex, variable in length but generally a little shorter then the calyces.
