Lupinus vallicola

Lupinus vallicola has violet flowers that are typically 2cm in diameter and have five petals. The seeds are bean-shaped and start off green before turning a dark brown colour. They are about 1cm in length.^[1]

Commonly found in western North America, Lupinus vallicola natively grows in California, western Nevada, Oregon, and Washington, United States. It is also found in British Columbia, Canada.^[2]

Like most lupines, Lupinus vallicola grows well in moderately fertile sandy soil that is well drained. The soil quality does not have to be high, as they can grow in poor soils due to their nitrogen-fixing roots.^[3]
