Oenothera missouriensis), the bigfruit evening primrose, Ozark sundrop or Missouri evening primrose, is a species of flowering plant in the evening primrose family Onagraceae, native to Mexico and the south-central United States, where it is found in calcareous prairies and limestone outcrops. This herbaceous perennial produces a red stem 6–12 in. (15-30 cm) in height. The large (3 inch) wide flowers are cup shaped, canary yellow and have a mild fragrance. They are produced in great numbers from early to mid summer. Leaves are dark green and lanceolate, and bunched along the trailing stem. The seed pods are 4-winged and 2 to 3 inch long. The seed pods are often used in flower arrangements. This plant is also grown in gardens for its flowers. It is suitable as a groundcover in poor, stony soil which does not become waterlogged in winter, in full sun. It has gained the Royal Horticultural Society’s Award of Garden Merit.
