Vernonia lettermannii 'Iron Butterfly'
This is a new selection from Dr. Allen Armitage. ‘Iron Butterfly’ has soft, needle-thin foliage that resembles Amsonia hubrichtii and compact busy habit. It tolerates hot, dry locations and is covered with purple flowers in late summer. Butterflies love them. This looks like a fantastic perennial, selected from Vernonia lettermannii, which is a native of Arkansas. Purple flowers appear between July and August.
