Ironweed-Narrowleaf

Similar to 'Iron Butterfly in texture and habit, this nativar is taller with larger, deep purple flowers that pollinators adore. Its disease resistant foliage flushes red-purple in fall, adding to its appeal. Forms a sturdy, upright clump of interlocking stems that won't flop. Received 5 stars in the Chicago Botanic Garden Trials. Breeder: Dr. Jim Ault.
