About this plant
Erechtites hieraciifolius, commonly called fireweed or American burnweed, is a fast-growing annual or biennial herb known for colonizing disturbed areas such as burned or cleared land. It has deeply lobed leaves and produces clusters of small, fluffy flowers that turn into seed heads dispersed by the wind. This plant plays a role in natural succession by stabilizing soil and providing early habitat for insects.
