Verbena perennis produces one to several stems from a woody base, Plants are perennials, and the new growth mingles with dry stems from previous years. Stems branch regularly, from the widely-spaced leaf nodes; they usually have a fine covering of very short, stiff hairs, often slightly glandular. Leaves are short and linear, with a lighter-colored midvein. Leaves may have a pair of small lobes at the base. Leaf margins are rolled under.
The narrow, elongated inflorescence is produced at the tips of the branches. Flowers are subtended by short, ovate, pointed-tipped bracts. The calyx is less than a quarter of an inch in length, red-purple in color, and hairy, while the pink to bluish corolla is around 1.5 times as long, and has five spreading lobes, wavy along the outer edges. Flowers mature from the base of the cluster upwards.
