Description

Appalachian Ironweed is a native wildflower in the daisy family that is typically found along stream banks and in low-lying areas in rich wooded areas.  Numerous sources indicate that this plant is rare. 

It has been said that the common name Ironweed comes from its rigid, tough stems as well as the rust color of the faded flowers.

Cutting the plant back in the spring will promote the growth of additional flowering stems.

Insects, Diseases, and Other Plant Problems:  Although it is pest resistant, deer are attracted to this plant.
