Ageratina thyrsiflora
Congested Snakeroot is a North American daisy-family shrub native mostly to northwestern Mexico, with a single record from Arizona. It is a wild species rather than a common garden plant, so care is best matched to its dry, warm native habitat.
Ageratina thyrsiflora is a North American species of plants in the family Asteraceae. It is native mostly to northwestern Mexico (states of Chihuahua, Durango, Jalisco, Sinaloa, and Sonora). The range extends just barely into the United States, a single herbarium specimen having been collected in 1929 just north of the border town of Nogales, Arizona.
