Bassia scoparia

Bassia scoparia is a large annual herb in the family Amaranthaceae (sensu lato) native to Eurasia. It has been introduced to many parts of North America, where it is found in grassland, prairie, and desert shrub ecosystems. Its common names include ragweed, summer cypress, mock-cypress, kochia, belvedere, World's Fair plant, burningbush, Mexican firebrush, and Mexican fireweed, the provenance of the latter three names being the herb's red autumn foliage.
