Liatris pycnostachya (Asteraceae)
Prairie Blazing Star
This is a marvelously tall and showy species — upright wands of tightly clustered pale-purple flowers are a fiesta for butterflies! Narrow grassy foliage has a wonderfully fine and airy texture in the garden. A common and wide-ranging Blazing Star found from TX up through the Mississippi Valley and into the Northeast; prefers full sun and well-drained soils, especially in winter. Bill Cullina calls this Liatris "the best species for perennial borders and formal gardens."
