This airy perennial forms a loose clump.  It has butterfly-shaped blooms on long arching stems that are bright pink.  They appear in summer and may bloom into the fall if deadheaded.  The dark green leaves have maroon blotches on them, adding all-year interest.  It works well for mass plantings, natural areas, and mixed borders.

This plant is heat and somewhat drought-tolerant but cannot tolerate wet, poor-draining soils.  It performs best in full sun.
