Boechera grahamii is a compact native wildflower that forms small clumps with narrow leaves and delicate white or pale pink flower clusters in late spring. This drought-tolerant perennial works well in rock gardens or naturalized areas where it can establish without much maintenance. It dies back to the ground in winter and emerges again in spring.
