Ageratina herbacea is a North American species of flowering plants in the family Asteraceae known by the common names fragrant snakeroot and Apache snakeroot. [3] It is native to desert regions ( Sonoran, Mojave, and Chihuahuan Deserts) of the southwestern United States (southeastern California, southern Nevada, southern Utah, Colorado, Arizona, New Mexico, western Texas) and northern Mexico ( Baja California, Chihuahua, Coahuila, Sonora). It grows in rocky slopes in conifer forests and woodlands. [4] [5] [6] [7]
Ageratina herbacea is a perennial herb growing a green, fuzzy stem from a woody caudex to heights between about 50 and 70 centimeters. The leaves are yellow to green or grayish and are triangular to heart-shaped. The inflorescence is a cluster of fuzzy flower heads under a centimeter long containing long, protruding white disc florets and no ray florets. The fruit is an achene a few millimeters long with a rough bristly pappus. [8]
Ageratina is derived from Greek meaning 'un-aging', in reference to the flowers keeping their color for a long time. This name was used by Dioscorides for a number of different plants. [9]
