Prairie bluets is a delicate native wildflower that forms small, neat clumps with tiny four-petaled white to pale blue flowers. This compact perennial blooms reliably from May through July and requires minimal water once established. Its small stature and tidy growth habit make it suitable for rock gardens, borders, or as groundcover in sunny areas.
