Oenothera macrocarpa, Missouri Evening Primrose

A cherished Missouri native perennial, Missouri Evening primrose, Oenthera marcrocarpa, boasts brilliant large yellow flowers. Low growing, sprawling plants 6-12″ tall produce huge 3-5″ cup-shaped bright yellow flowers in spring and summer. Their delightful softly fragrant blossoms only last one day, usually opening in late afternoon and remaining until the following morning. Interesting winged 2-3″ seed pods follow. Easy to grow in full sun and most soils. Also known as Oenothera missouriensis.
