Ageratina havanensis, the Havana snakeroot^[3] or white mistflower,^[4] is a species of flowering shrub in the family Asteraceae, native to the south-western United States (Texas), Cuba, and north-eastern and east-central Mexico (Veracruz, Tamaulipas, Coahuila, Nuevo León, Hidalgo, San Luis Potosí, Puebla, Guanajuato, Querétaro).^[5] Unlike many other species of Ageratina, it is evergreen.^[6]^[7]^[8]^[9]

Etymology

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.^[10]
