Description

Ironweed is an herbaceous native perennial wildflower in the Aster family and is found in all areas of NC. It may grow 5 to 8 feet tall with deep purple flowers that appear in clusters from mid-summer to mid-fall on strong stems. This low maintenance wildflower naturalizes easily and is adaptable to garden conditions.

Ironweed prefers rich moist acidic soils but will grow in average moist to wet soils in full sun. Use in a rain garden, cottage garden, meadow, along streams or ponds or the back of the border. If a shorter plant is desired, prune it back in spring to about 2 feet. It is attractive if blooming occurs at different heights, so prune to different heights for this effect.
