Gutierrezia diversifolia |
Gutierrezia sarothrae is a species of flowering plant in the daisy family known by the common names broom snakeweed and perennial matchweed. It is native to much of the western half of North America, from central Canada to northern Mexico. It can be found in a number of desert, grassland, and mountain habitats. This is a small, dense, bushy subshrub reaching maximum heights around half a meter. The multibranched stems and twigs are greenish or tan when young and age to woody brown. There are scattered narrow to thready leaves along the branches. The plant flowers abundantly in inflorescences of a few flowers each. The flower is about a centimeter long and bright golden yellow with a center of a few long, protruding disc florets and a fringe of ray florets. The plant is toxic to livestock in large quantities, due mainly to the presence of saponins and concentrated selenium.
