American Germander, Wood Sage, Canada Germander - Teucrium canadense
|
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.
