Yellow Bush Lupine

Lupinus arboreus

Honeybees forage on Yellow Bush Lupine primarily for its high pollen loads, with moderate nectar availability supporting colony needs during the blooming period. Peak bloom hits in late spring to midsummer, providing a reliable resource in coastal gardens. It can spread aggressively and become invasive north of its native range in California, so monitor and manage accordingly to avoid ecological issues.
