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] 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.
