Dense lupine is a striking native perennial from California and Nevada that produces tall spikes of colorful flowers in partial shade to full sun conditions. Plant it in well-draining, slightly acidic soil and avoid overwatering, as lupines are nitrogen-fixers that prefer lean soil conditions. This fast-growing species is a rewarding choice for native plant gardens and draws a wide variety of pollinators throughout its blooming season.
