Chenopodium rubrum L.
Common Name: COAST BLIGHT
Coefficient of Conservatism: *
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Ad A-Forb

Disturbed ground, shores, and river banks. Considered native in North America, but like other of our weedy species, apparently not so in Michigan where first collected in 1894 in Bay Co.

A Washtenaw Co. collection previously reported in Michigan Flora and earlier iterations of the website as var. humile (Hook.) S. Watson, has been re-identified as C. capitatum var. parvicapitatum S. L. Welsh. It differs from C. rubrum and its var. humile in having the perianth segments only 3, the seeds all vertical, and inflorescences in clusters on unbranched stems. Chenopodium rubrum var. humile is not known from Michigan.
