Named for its tough stem, Ironweed has excellent posture and never slouches in the garden. The flowers of Ironweed are like crimson torches in the late summer landscape. An excellent addition to the pollinator garden, the brilliant purple-crimson bloom color is very attractive to butterflies. Ironweed is a host plant for the American Painted Lady butterfly, as well.

The dark rigid stems topped with contrasting fluffy seed heads, offer excellent late season color and texture.

Although it grows naturally in moist soils, and tolerates brief flooding, it also does equally well in average garden soils. It also grows taller in moist soils. The plant height may be reduced by cutting back the stems in late spring. Ironweed can be a fairly aggressive spreader. This can be mitigated by removing the flower heads, or some of them, before they go to seed.

In the Garden: Effective in background borders, cottage gardens, rain gardens, wildflower meadows and naturalized plantings.
