lupine

Honeybees visit bigleaf lupine primarily for its abundant, high-quality pollen, as the flowers produce minimal nectar. Peak bloom aligns with late spring to early summer, offering an important early-season pollen resource after spring ephemerals. Tall flower spikes can reach 1-1.5 meters and may require staking in exposed sites to prevent lodging; the plant fixes nitrogen and thrives in well-drained, slightly acidic soils.
