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.[4]

The species is named for John Gill Lemmon (1831–1908), husband of botanist Sara Plummer Lemmon (1836–1923).[5]
