Ironweed

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.
