Ironweed - Narrowleaf
'Iron Butterfly' Narrowleaf Ironweed has many bright purple star-like flowers that appear in late summer and fall. Foliage is delicate and thread-like on a compact plant.

One of the native plants chosen by Piet Oudolf for the newly planted meadow garden at Delaware Botanic Gardens. 2023 PHS Gold Medal Plant.
