Riverbank Lupine - Lupinus rivularis
 
Commonly known as riverbank lupine, this colorful perennial is native to the wetlands and riverbanks of the western United States and Canada. Typically growing to heights of 1 to 5 feet, it features palmate leaves that radiate from a central point, providing an attractive green backdrop. In late spring to early summer, riverbank lupine produces striking spikes of blue to purple flowers, which attract a variety of pollinators, including bees and butterflies. Thriving in moist, well-drained soils, this plant is often used in restoration projects and gardens, enhancing both beauty and biodiversity.
