The decurrent false aster is protected under the Endangered Species Act as a threatened species. It is a perrenial plant found in moist, sandy floodplains and prairie wetlands along the Illinois River. Although not very tolerant to prolonged flooding, this plant relies on periodic flooding to scour away other plants that compete for the same habitat.
