American Germander, Wood Sage, Canada Germander - Teucrium canadense


Family: Lamiaceae - Mint family Genus Common Name: Germander Native Status: NativeDicot Perennial Herb
Teucrium canadense - American Germander, Wood Sage, Canada Germander. While there may be as many as 250 species of Germander in the world, only eight are found in North America, with just five of those being native to the continent. The non-native species have limited distribution, as do four of the native species. American Germander - Teucrium canadense, however, is widely distributed on the continent, being found in each of the lower 48 states as well as most of Canada. This is indicative of its weedy nature, and it is considered invasive by some weed authorities.

The flowers of American Germander are irregular, with a two-lipped (bilabiate) corolla which is a pinkish-tinged white with pink to purple spotted markings on the lower lip. The upper lip are the two upright lobes with the tips nearly touching in this photo; the lower lip consists of the two small spreading lateral lobes and the huge hanging lowest lobe. The stamens and pistil are exserted from the upper lip.
