Dudley's Lupine is a rare California-endemic subspecies of broadleaf lupine, valued by native plant enthusiasts for its tall, colorful flower spikes and ecological importance as a pollinator plant. It performs best in well-drained, slightly acidic soil in a partially shaded to full-sun coastal or foothill garden setting. Water consistently during the growing season and deadhead after flowering to keep plants tidy and to prolong blooming.
