Evening Primrose Seeds (Oenothera biennis) - 100mg Night Blooming Pollinator Flower

Evening Primrose (Oenothera biennis) is a charming wildflower known for its bright yellow blooms that open in the evening and remain open through the next morning. This biennial plant is a favorite among gardeners for its ability to attract pollinators, including moths and bees, and its tolerance of poor soils. It is often used in wildflower gardens, meadows, and naturalized areas, where its tall stems and luminous flowers add a touch of magic to the landscape.

Evening Primrose is easy to grow from seed and can self-sow readily under favorable conditions. Its deep taproot makes it drought-tolerant once established, and its flowers provide a late-day food source for pollinators. Whether you're creating a pollinator-friendly garden or looking to add a unique night-blooming plant to your beds, Evening Primrose is a rewarding choice.

Planting & Care

Evening Primrose seeds can be sown directly outdoors in fall or early spring. Prepare a weed-free seedbed and scatter the seeds on the surface, pressing them lightly into the soil; do not cover deeply as light aids germination. Keep the soil consistently moist until seedlings emerge. Once established, thin seedlings to the recommended spacing to allow for healthy growth.

Evening Primrose thrives in full sun and well-drained soil. Water regularly during the first growing season to help establish a deep root system, but reduce watering thereafter as the plant is drought-tolerant. Mulching around the plants can help retain moisture and suppress weeds. In the second year, stake tall stems if necessary to prevent lodging. Allow some flowers to go to seed to encourage natural reseeding for future blooms.
