Western Spiderwort is a native perennial of dry prairies and sandy soils across the Great Plains, bearing clusters of rose-purple to bright blue three-petaled flowers in spring and early summer. Growing 1–2 feet tall, it is more drought-tolerant than eastern spiderwort species and is adapted to sandy, well-drained soils. The flowers last only a morning but are produced in succession over several weeks. It is an important early-season pollinator plant on dry prairies.
