Scutellaria integrifolia grows 1–2 feet tall, is usually branched near the base and has erect stems. Leaves are opposite. Those near the bottom are often coarsely toothed, 1/3–1 1/4 inches long; upper leaves are untoothed, narrower, and up to 2 inches long. The bluish-lavender, 2-lipped flowers are clustered or solitary in the axils of bract-like upper leaves, together forming an elongated cluster along the finely hairy square stem.
The many different Skullcaps are recognized by the tiny projection, or hump, on the top of the calyx surrounding the base of the flower.
