Description

Turtlehead is a clumping native perennial in the plantain family (Plantaginaceae) found in moist forested areas of swamps and bogs in the southeastern and central United States. It is considered rare in NC but can be found in the coastal and mountain areas. The genus name comes from the Greek word chelone, meaning tortoise in reference to the turtlehead shape of the flowers. Specific epithet means lopsided or oblique.

Clump-forming turtlehead grows 2 to 3 feet tall and 1 to 2 feet wide in partial shade to dappled sun, and does best in humus-rich, moist to wet soil. It is adaptable to any fertile, moist garden soil in sunny to shady locations. Propagate by division, seeds or cuttings.

The rose to purple snapdragon-like flowers occur on terminal spike-like clusters in late summer to fall. Each flower is about 1.5 inches, has two lips and a sparse yellow beard inside the lower lip. It is a host plant for the Baltimore checkerspot butterfly and is pollinator-friendly.

Use this plant along streams, ponds or bogs and in pollinator, native, butterfly, woodland and water gardens.

Insects, Diseases, and Other Plant Problems:   No significant problems. Mildew can occur if the soil is too dry or overcrowding occurs.Too much shade may cause the plant to need staking.
