This week we highlight a flower many of you may know and nearly all New Mexican residents have seen, matchbrush (Gutierrezia sarothrae), also commonly known as snakeweed. It can cover entire fields, a sign of overgrazing. Since matchbrush is not eaten by cattle, it takes advantage of the lack of competing plants in overgrazed areas. You will often find matchbrush growing in lower elevations: toward the end of the mesa tops, in the canyon bottoms, and across grasslands. It does well in full sun and the hotter temperatures found in these areas.
