Annual yellow lupin
Lupinus luteus
Annual Yellow Lupin is a cheerful, fast-growing plant with bright yellow flower spikes that thrives in full sun to partial shade and well-drained, slightly acidic soil. As a member of the legume family, it fixes nitrogen in the soil, making it a great companion plant and green manure crop. Sow seeds directly in the garden after the last frost and deadhead spent blooms to extend the flowering season.
