200 Seeds Evening Primrose Oenothera lamarckiana Yellow Wildflower Pollinator Garden

Evening Primrose (Oenothera lamarckiana) is a charming biennial wildflower known for its bright yellow, cup-shaped blooms that open in the evening and remain open through the following morning. This cottage-garden favorite brings a soft, natural look to borders and meadow-style plantings, attracting bees and other pollinating insects during its long summer bloom period.

Often grown as an ornamental for wildflower meadows, cottage gardens, and informal borders, Evening Primrose offers a long flowering season and self-seeds readily under favorable conditions. The vivid yellow flowers contrast nicely with fine green foliage and pair well with other low-maintenance wildflowers. Seeds are easy to sow directly in prepared garden beds.
