Oenothera lindheimeri is a perennial herbaceous plant growing to 50–150 cm tall, with densely clustered branched stems growing from an underground rhizome. The leaves are finely hairy, lanceolate, 1–9 cm long and 1–13 mm broad, with a coarsely toothed margin. The flowers are produced on a 10–80 cm long inflorescence; they are pink or white, 2–3 cm diameter, with four petals 10–15 mm long and long hairlike stamens, and are produced from the beginning of spring until the first frost.
