Oenothera

Evening Primrose

Oenothera, commonly known as Evening Primrose, is a charming perennial valued for its bright, cup-shaped flowers that open in the evening and close by midday. Blooming from late spring through summer, its golden-yellow flowers create a cheerful display while adding a unique element of nighttime interest to the garden. The upright or spreading growth habit makes Oenothera suitable for borders, rock gardens, wildflower meadows, and naturalized landscapes.

Highly adaptable and easy to grow, Oenothera thrives in sunny locations and tolerates heat, drought, and poor soil conditions once established. Its flowers attract pollinators such as bees and moths, contributing to garden biodiversity. Some species also offer medicinal or ornamental seed pods that extend visual interest beyond the flowering season. With minimal care requirements and reliable blooming, Oenothera is an excellent choice for gardeners seeking a resilient, low-maintenance perennial with natural charm.

Water regularly during establishment. Once mature, Oenothera prefers dry to moderately moist soil.
