Columbia River Wormwood (Artemisia lindleyana)
Columbia River Wormwood, scientifically known as Artemisia lindleyana, is a subshrub belonging to the genus Artemisia. It is also commonly referred to as Columbia River mugwort, riverbank wormwood, and Columbia River Sagewort.
Considerations for Pets and Children
- Fort Nez Perce was located on the left bank of the Columbia River six miles below, which supports little vegetation, except the wormwood and thorn- bushes.
- Artemisia arborescens (tree wormwood), another species in the same genus, is noted as a very bitter herb. While this refers to a different species, the bitterness could be a factor if ingested by pets or children.
