Teucrium canadense L.
American Germander, Canada Germander, Canadian Germander, Germander, Hairy Germander, Wood Sage
Lamiaceae (Mint Family)
USDA Symbol: TECA3
A rhizomatous perennial with a terminal, spike-like cluster of lavender-pink flowers on a downy square stem.
The most distinctive feature of the Teucrium species is the seemingly 1-lipped corolla. The common name germander was originally altered from a Greek name for ground oak, chamaidrys. Two smaller, bushier species have been introduced from Europe into eastern North America: Woodland Germander (T. scorodonia), with yellow flowers, and Cutleaf Germander (T. botrys), an annual with purplish flowers.
