Named for its tough stem, Ironweed has excellent upright form in the garden. The intense purple bloom color stands out in the late summer landscape, attracting many butterflies and other pollinators. While this tall stately plant occurs naturally in moist soils and tolerates brief flooding, it grows equally well in average garden soils. The plant height may be reduced by cutting-back the stems in late spring. Ironweed can be an aggressive spreader by seed and may not be suitable for smaller settings, but is very effective in background borders, cottage gardens, rain gardens and wildflower meadows. Self-seeding can be mitigated by removing some of the flower heads before they go to seed. However, the dark rigid stems topped with contrasting fluffy seed heads do offer beautiful late season interest.
