Oenothera macrocarpa

Missouri Evening Primrose (Oenothera macrocarpa) is a low-growing perennial known for its large, bright yellow flowers that bloom in late spring and summer. This plant typically forms a sprawling mound, with stems reaching 6-12 inches tall and spreading up to 2 feet wide. It thrives in full sun and prefers dry, rocky, or sandy soils, making it well-suited for rock gardens and xeriscapes. Missouri Evening Primrose is highly drought-tolerant and requires minimal watering once established. Its showy blooms open in the evening and attract pollinators such as moths and bees. This hardy native is valued for its resilience and striking appearance in sunny, well-drained locations.
