Coarsely toothed leaves 2 to 3 inches long covered with dense hairs, generally oval and pointed on both ends; opposite attachment at the stem with no leaf stem. The main stem is square and may be a reddish color. Leaf color may be yellowish green.
Notes:Hoary Vervain tends to grow in clumps. It might be confused with Blue Vervain, but Blue Vervain has smaller flowers, its leaves are long and narrow rather than oval, and it prefers moist habitats. The square stem and opposite leaves may also confuse Hoary Vervain with a member of the Mint family.
