Oenothera missouriensis (also Oenothera macrocarpa)
Common Name: Ozark Sundrops
Canary yellow, mildly fragrant, 3 inch wide flowers are produced in great numbers over dark green, lanceolate leaves from early thru midsummer. Following the substantial blooms, 2 to 3 inch long, 4-winged seed pods are produced which are beautiful in dried floral arrangements. The trailing habit and drought tolerance of this perennial makes it ideal for softening the edges of pathways or planting in rock gardens.
