Riverbank Lupine

Lupinus rivularis  Riverbank lupine, also known as streambank lupine, provides striking and long-blooming visual interest and a faintly pleasant scent. Its radially-compound leaves and whorls of light-purple pea-like flowers on vertical spires are an iconic sight in the Pacific Northwest. This species is fabulous in habitat gardens, growing quickly into a robust perennial or subshrub that produces pollen and nectar for humblebees, bumblebees, other native pollinators and beneficial insects. By fall, the flowers die back into spiraling seed capsules considered ornamental to some (like us!). Plant type/canopy layer: deciduous, perennial, herbaceous plant  Size at maturity: 36- 48” tall, 24-36” wide Light requirements: full sun, part sun/part shade Moisture requirements: dry to moist soil Bloom time: March - August Growth rate/ease: fast growing, easy to grow Wildlife support: flowers attract and provide nectar to hummingbirds, adult butterflies, bees and other insect pollin
