Lupine (Lupinus species) - Eight species of lupine are scattered in various habitats throughout the Mid-Columbia,providing one of the most striking wildflower displays of the spring. Sulphur lupine (Lupinus sulphureus) and Velvet lupine (Lupinus leucophyllus) are two of the most common species in the Columbia Basin. Velvet lupine can be easily identified by the small, soft hairs covering the plant. All lupines have palmately compound leaves; the flowers, which may be purple, blue, yellow or white (depending on the species), are borne on upright spikes which may be more than 7 inches in length. These perennial forbs vary greatly in height; low-growing species may be only 4 to 6 inches tall, while other species can grow to more than 2 feet.
