Maryland Native Plants for Summer

Scutellaria incana – Hoary Skullcap

Hoary Skullcap

Scutellaria incana – Hoary Skullcap is easily grown in average, dry to medium, well-drained soil in full sun to part shade. Best on dryish, sandy or clay soils. Scutellaria incana, commonly called skullcap, is a native wildflower that occurs in open woods, clearings, on slopes and along streams. Grows to 3′ tall. Small, two-lipped, purplish blue flowers (typical mint family) appear in branching, loose racemes in summer. Toothed, ovate, medium green leaves. Square stems are hoary (covered with minute white hairs), hence the sometimes common name of hoary skullcap. Skullcap refers to the skull – or helmet – shaped calyx of the flower. This plant is a member of the mint family and has bitter-tasting  so deer and rabbits usually ignore this plant.
