Stalked glands are present above the second internode. The leaves are attached oppositely, petioles are 0.75-1.0in (1.8-2.5 cm) long, and blades are more or less orbicular shaped below mid-stem and broadly ovate and smaller above, 1.0-1.2in (5-6cm) long, 1.3-2.0in (3.5-5.5cm) wide. Leaf apices are obtuse to rounded and margins are wavy. Both surfaces are hairy, the upper often with stalked glands. Inflorescense is a system of paired, lateral racemes with bracts changing from elliptic and crenate to oblanceolate with smooth margins. Flowers are irregular with the characteristic "capped" calyx which lacks stalked glands; flower stems are hairy, the petals are blue, fused, somewhat hairy, 0.9-1.0in (20-24cm) long, with a gradually dilating tube, the lower lip entire. Four stamens are present, extending beyond the petals; the stigma is two-parted. Fruits consist of 4 small nutlets. The flowering period is from late June to early August and fruits remain on the plant until mid-August at the latest. In this area the plants often fail to make flowers and fruits. Both are heavily browsed by deer. Overall the plants somewhat resemble catnip, another mint, in color, leaf shape, and in being softly hairy. Scutellaria ovata is very similar, but differs in the following:

  • The calyx lobes have stalked glandular hairs in S. ovata, but they are absent in S. ocmulgee.
  • The 2nd stem section (internode) before the base of the flowering portion lacks stalked glandular hairs in S. ovata whereas they are present in S. ocmulgee.

General Habitat: Typically found in rich soils under old-growth hardwoods on slopes above streams, often growing with geranium, heart-leaf, and lop-seed.
