Lupinus Rivularis (Riverbank Lupine) Seeds

Riverbank Lupine (Lupinus Rivularis) is a native perennial wildflower with tall blue flower spikes that bloom in late spring to early summer. It thrives in full sun to partial shade and moist, well-draining soil, and self-seeds to return year after year. Scarify seeds before sowing directly outdoors in fall or early spring at 1/8 to 1/4 inch deep; germination takes 14-21 days at 55-70°F.
