The Bitterroot plant, scientifically known as Lewisia rediviva, is a flowering perennial native to the western United States. It is known for its beautiful pink or white flowers and is often found in rocky, mountainous areas. The plant is named after the Bitterroot Valley in Montana, where it is commonly found. The Bitterroot Valley is located in western Montana and is known for its stunning landscapes and rich history.
