Erigeron lemmonii is a branching perennial herb up to 60 centimeters (2 feet) tall, producing a woody taproot. The leaves and the stem are covered with hairs. The plant generally produces only 1-3 flower heads per stem, each head with up to 60 white ray florets surrounding numerous yellow disc florets. The species grows shaded cliff-faces in pine-oak forest.[2][4]

The species is named for John Gill Lemmon (1831 - 1908), husband of prominent American botanist Sarah Plummer Lemmon (1836 – 1923).[2]
