Giant Ironweed
6-8 feet tall and 3-6 feet wide, Giant Ironweed (Vernonia gigantea) can provide fall fireworks in the garden or can be pruned back in mid-summer to result in a more manageable maximum height. It’s most effective for pollinator benefit and garden color when planted in multiples of three or more plants. Site plants in full sun in moist soil. Giant ironweed can tolerate wet feet for extended periods of time. They will self-sow, so deadhead when flowers fade to keep the garden tidy. Relatively easy to grow, and not prone to pest and disease problems. Pairs well with other prairie wildflowers and grasses.
