The species has been reported from every state in the United States except Alaska, Hawaii, and Utah, as well as from British Columbia, Manitoba. Ontario, Quebec, New Brunswick and Nova Scotia.〔(Flora of North America v 4 p 510 )〕 Carpetweed has narrow, whorled leaves of 3-8 at each node. Leaves are about 1–3 cm in length.
