Small plant, generally less than a foot tall. Stems square in cross section, often hairy. Leaves small, opposite each other, without stalks, sometimes hairy, sometimes with a few large teeth. Flowers on definite stalks, blue to violet, with internal purple-spotted white patch, tubular, with a broad apron below in front, sticky hair on the outside. The sticky hairy sepals are fused together and have a pominent hump on the back. The sepals remain after the tubular flowers fall, looking like a pair of lips. Blooms in late spring to early summer

A small native of open rocky areas. In Wildwood favors the upper west slope around the cell tower and watertanks.

The prominent hump on the fused sepals identifies this as a skullcap. Showy skullcap (S. serrata) and hairy skullcap (S. elliptica) are larger and have larger flowers and toothed leaves. Veined skullcap (S. nervosa) has white flowers.
