Description

Baikal skullcap is a herbaceous perennial native to East Asia and Siberia, forming a low mound 12–18 inches tall and wide. The square stems bear opposite, lance-shaped leaves with toothed margins. In summer, it produces tubular, two-lipped blue-purple flowers in one-sided racemes. The thick, branched roots are golden-yellow when mature—hence the name "Golden Root."

Cultivation

Prefers full sun to partial shade and well-drained, sandy or loamy soil. Drought tolerant once established. Hardy in USDA zones 4–8. Propagate by seed sown in spring or by root division in early spring or fall. Space plants 12 inches apart.

Medicinal Significance

A cornerstone of Traditional Chinese Medicine (known as Huang Qin), the dried roots are harvested after 3–4 years. They contain flavonoids like baicalin, wogonin, and oroxylin A, studied for anti-inflammatory, antioxidant, antiviral, and hepatoprotective properties. Used in formulas for respiratory infections, allergies, and liver support.

Garden Value

Attractive in rock gardens, herb borders, and dry meadows. The blue flowers draw bees and butterflies. Deer and rabbit resistant.
