- Description
-
Downy skullcap is a native perennial wildflower in the Lamiaceae (mint) family. Found growing in shady dry forests and open woodlands, and along slopes and streambanks. The square stems are covered with fine white hairs and small purplish-blue flowers bloom in loose racemes in summer. The genus name comes from the Latin word scutella meaning a small dish or saucer. These plants have bitter-tasting leaves so are usually ignored by deer and rabbits.
It prefers moderate moisture in well-drained soil but tolerates sandy, clay, and poor soils. It grows in dry woods or clearings. This plant is tolerant of heat and drought.
This plant was selected as the 2014 NC Wildflower of the Year, a program managed by the North Carolina Botanical Garden with some financial support from the Garden Club of North Carolina.
Insects, Diseases, and Other Plant Problems: No serious problems.
