plant sale text: Broadleaf ironweed is found mainly in the piedmont region in dry fields, making this plant a great selection for a dry sunny site. Its tall stature is sited well in the back of a perennial border or for naturalizing a field. Purple-topped stems in late summer are butterfly magnets! Broadleaf ironweed will spread by seed. Pinch back the tips in early summer to yield a bushier form less likely to lean.
