This species of spiderwort is a clump-forming herbaceous perennial which grows up to 3′ tall. Violet-blue to purple, three-petaled flowers (.75-1.5" diameter) accented by contrasting yellow stamens open up, a few at a time, each for only one day, from terminal clusters (umbels) containing numerous flower buds. Flowers bloom in succession from late May into early July. Arching, iris-like, dark green leaves up to 1′ long and 1 inch wide are folded lengthwise forming a groove.

Grow in average, medium moisture, well-drained soil in part shade to full shade. Prefers moist, acidic soils. Tolerant of poor soils. Divide clumps when they become overcrowded. Foliage declines after flowering and should then be cut back almost to the ground to encourage new growth and a possible fall bloom. Can self-seed and spread in ideal growing conditions.
