Squaw Vine (Mitchella repens)

About

Blue cohosh is an upright perennial herb reaching 3 feet in height, with large three-lobed leaves, yellow to purple flowers, and striking blue berries. It grows wild in much of eastern North America from Manitoba to Alabama, preferring woodland valleys and damp, north-facing slopes. The name 'cohosh' comes from the Algonquin language, and the plant was a popular remedy among many Native American tribes.

Squaw vine is an evergreen herb that grows up to 1 foot tall, forming mats on the ground. It has rounded shiny leaves, fragrant white flowers on flowering stems, and produces small bright red berries. The plant grows in dry woodland sites in the eastern and central United States.
