In mid to late summer large clusters of frilly deep purple flowers sit atop short sturdy stems that are covered in fine dark green narrow foliage giving this tough as nails perennial as soft pleasing texture even when not in flower. Iron Butterfly Ironweed is as tough as its name implies, even though this is a selection of a rare species, it can tolerate short periods of drought or periodic inundation with ease. A nice tightly clump forming perennial from the works of Dr. Allen Armitage and the UGA horticulture program. The flowers provide much needed late summer fodder for bees, butterflies, and other garden beneficials. Item# 10929.
