Oenothera biennis

Oenothera biennis, commonly known as evening primrose, is a tall, biennial plant native to North America. It features yellow flowers that bloom in the evening or early morning, attracting pollinators like bees. The plant has rosette leaves in its first year, then produces a tall, sturdy stem with multiple flowers in its second year. Its seeds are often used to produce evening primrose oil, rich in omega-6 fatty acids, which may support skin health, hormonal balance, and inflammation reduction. The plant is also valued for its ornamental beauty and ecological role in its native habitat.
