Description

American burnweed is in the Asteraceae (daisy) family. It prefers man-made or disturbed habitats(roadsides, railway lines, ditches), coastal areas, shores of lakes and rivers, meadows and fields, wetland margins. It is often found in sites associated with beaver activities causing cyclical flooding and drainage and is a common landscape weed. Population explosions may occur in these habitats after human-induced disturbances or other conditions where competition is reduced, but they generally die back as natural succession leads to less open environments.  

The plant often branches and grows in a clump with multiple stems.

 Flower heads of American burnweed are held upright, whereas thickhead flowers droop downward. Plants flower in summer to early fall then die after frost. Seeds are wind-dispersed and can produce multiple generations each growing season. This species benefits from fire and is often one of the earliest pioneer species of areas that have recently burned, hence some of its common names. It prefers moist sites but can handle gravelly soil and some degree of dry conditions. It also grows well in urban areas and around humans.

American burnweed is well managed by broad-spectrum herbicides but most single-active ingredient herbicides are less effective.
