Lupinus caudatus

Tailcup lupine (Lupinus caudatus) is a robust western native perennial that produces tall spikes of blue to violet flowers beloved by pollinators. It thrives in well-draining, even poor or sandy soils and is quite drought-tolerant once established, requiring only occasional deep watering. Plant it in a sunny spot in a native, wildflower, or meadow garden and avoid overwatering or rich fertilizers, which can reduce flowering.
