Asarum canadense


Canadian wild ginger, Wild ginger


Aristolochiaceae (Birthwort Family)



Asarum canadense (Canadian wild ginger)
Sherman, Doug
This low, colony-forming perennial grows only 4-8 in. high. Each plant bears a pair of large, velvety, heart-shaped leaves. Growing at ground level in the crotch between 2 leafstalks is a single darkish red-brown to green-brown flower. The solitary flower is at ground level, hidden below the leaves. A similar plant with greenish-purple flowers, Hexastylis arifolia, has more triangular, evergreen leaf blades.

The fleshy rootstock, which has a strong, gingery flavor, can create a crowded network on the woodland floor, resulting in a dense ground cover of Wild ginger.
