Distinguishing Scutellaria spp. (Skullcaps) is rather tricky, but here are some key characteristics of Downy Skullcap: 1) Except for the lowest leaves, the leaf bases are well-rounded, rather than heart-shaped; 2) this species of Skullcap blooms later and grows taller than most; 3) except for the upper leaf surfaces, the entire plant is finely pubescent, and it has no sticky glandular hairs; and 4) the racemes of its flowers are terminal, rather than axillary.
