Oenothera missouriensis (Oenothera missouriensis) has several common names including Missouri Primrose, Ozark Sundrops, Glade Lily, Bigfruit evening-primrose, and Oklahoma Evening-primrose.  Missouri Primrose is a striking plant with large 3 to 4 inch lemon yellow flowers on sprawling stems and unusual vibrant winged seed pods.  Missouri primrose does not spread aggressively like some primrose plants and is very desirable in the wild flower garden.  This showy native wildflower is pollinated by night-flying Sphinx Moths.  Missouri Primrose is tough, drought tolerant, and requires little maintenance.  Missouri Primrose does best when planted in average well-drained soil in full sun to light shade in a rock garden with Penstemon (Showy Beardtongue), Alliums (Glade Onion), Dodecatheon (Shooting Star), Aromatic Aster, Rudbeckia (Missouri Black-eyed Susan) and Sporobolus (Prairie Dropseed). 

Native Oenothera macrocarpa Missouri Primrose wild flower seed germination is improved after a pretreatment of 4 to 6 weeks of cold moist stratification or when planted outside in the fall or early winter.

The showy flowers of native Oenothera macrocarpa Missouri Primrose  are found growing wild in open woods, savannas, cedar glades, and prairies in limy soils from Illinois and Colorado, south to Missouri and Texas.  Onagraceae (Evening Primrose Family)
