Ironweed, New York Ironweed

Ellen Nibali

Vernonia noveboracensis

The rich glowing purple of ironweed blooms pop against the warm autumn hues of goldenrod and mums. Depending upon its site, ironweed may reach 4 feet in the back of the perennial bed or soar 7 feet or more. This Maryland native is a butterfly favorite. Plant in full sun to slight shade. A perennial, it likes moisture and is a good candidate for a rain garden.  Give good air circulation by not over-crowding or planting flat against a wall. The brown fluffy seed heads are small and spread by wind.   Its name may refer to the strength of its stems or its general constitution.
