Western ironweed is a prairie native to the Great Plains states. Mid-summer to fall deep purple flowers clusters appear at the top of stalks. Ironweed can be invasive, rooting madly down to a foot so control could be difficult. Drought tolerant and cold hardy for the right location.
Confine it to prairie reconstructions and plant with grasses to check its spread. I think it would be suitable for a Western cottage garden when given enough room with limited watering.
Remove spent stalk in early spring.
