A tall-grass prairie perennial plant that grows up to 8 feet tall. Cup plant has square stems, and opposite set, egg shaped, toothed leaves with a cuplike base that holds water. Flower heads are rich, golden yellow and are grouped closely together at the tips of stems. Cup plant is found primarily on lowlands, along streams, alluvial thickets, floodplains, and on the edges of wet woodlands. Seeds are best sown as they ripe in a greenhouse and transplanted while they are young because they develop an extensive root system.
The flowers attract many pollinators and birds flock to eat the seeds and drink water from the cupped leaves. Portions from this plant are used for treatment of liver and spleen disorders. It has also been used to treat morning sickness. Pieces of the root are used as a face wash, to treat paralysis, back and chest pains, and lung hemorrhages.
