Oenothera macrocarpa, the bigfruit evening primrose,[1] 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.[2]
Description
This is a perennial herb that 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.
Uses
The seed pods are often used in flower arrangements. This plant is also grown in gardens for its flowers.[3][4] 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.[5][6]

There are five commonly accepted varieties. These are:
- O. macrocarpa var. fremontii - restricted to Kansas and southern Nebraska[7]
