The fruit of Bassia scoparia with the calyx attached is dull brown, but when hulled, it reveals dull black seeds, or dark to blackish-brown seeds in some escaped regions, such as Europe.The seeds are dispersed by wind and water and are transported when the whole plant detaches and rolls on the wind as a tumbleweed. The seed does not persist in the soil seed bank, dying within about a year if it fails to germinate.The species is a C4 plant, specifically of the NADP-ME type.It develops herbicide resistance unusually quickly, and quadruple-resistant populations have developed in North America.Bassia scoparia is native to a region ranging from Central Europe to Asia and is now widespread throughout the world. While having a variety of beneficial uses, it is also considered an invasive weed.
