Lupinus lepidus | WSU Vancouver
Have you seen L. lepidus?
In southern Washington, you'll find L. lepidus on volcanos, at around 6000-8000 feet in elevation (but only 3000-6000 feet at Mount St. Helens). I have found it growing on Mount Rainier, the Goat Rocks, and Mt. Adams, and nowhere in betweeen. If you find it somewhere west if Mt. Adams and South of Mount Rainier, please contact me!
