Birthwort is a vigorous spreading perennial with distinctive tubular yellow flowers historically used in herbal medicine, though it contains toxic aristolochic acids and should not be ingested. It grows well in partial shade with average moisture and spreads readily via rhizomes, so plant where it has room or use barriers to contain it. Handle with care and keep away from pets and children due to its toxicity.
