About This

• WHAT'S INCLUDED IN THIS EVENING PRIMROSE SEED 2-PACK? This 2-pack contains 1,150 Common Evening Primrose seeds total, with 575 seeds per envelope. These heirloom, non-GMO, open-pollinated Oenothera lamarckiana seeds produce bright yellow flowers for outdoor wildflower and pollinator gardens.
• WHEN DO EVENING PRIMROSE FLOWERS OPEN? Common Evening Primrose produces bright yellow, cup-shaped blooms approximately 2–3 inches across. Flowers open in the evening and remain open through the morning, providing color during dusk and early daylight hours.
• DO EVENING PRIMROSE FLOWERS ATTRACT POLLINATORS? Yes. Evening Primrose supports native bees, moths, and other evening pollinators. Its night-opening flowers make it suitable for pollinator gardens, wildlife-friendly borders, and naturalized meadow plantings.
• HOW DO I PLANT EVENING PRIMROSE SEEDS? Surface sow seeds or press them lightly into moist, well-drained soil without burying them deeply. Germination typically takes 14–21 days at 65–70°F. Thin seedlings to approximately 12–24 inches apart as they develop.
• WHEN SHOULD I SOW EVENING PRIMROSE SEEDS? Sow outdoors in spring after the last frost or during fall for natural establishment. Common Evening Primrose prefers full sun and well-drained soil and can be grown in sunny borders, wildflower meadows, and naturalized areas.
• IS EVENING PRIMROSE DROUGHT TOLERANT? Yes. Once established, Evening Primrose tolerates dry conditions and can grow in poor, sandy, or well-drained soil. Maintain moderate moisture while seedlings establish, then adjust watering based on growing conditions.
• WILL EVENING PRIMROSE RESEED NATURALLY? Evening Primrose can reseed in suitable growing conditions. Allow mature seed heads to develop if natural reseeding is desired. New seedlings may establish in open, sunny areas, helping maintain naturalized plantings over time.
• IS EVENING PRIMROSE A BIENNIAL PLANT? Yes. Common Evening Primrose (Oenothera lamarckiana) is a biennial suited to USDA Zones 4–9. Plants typically develop foliage during the first growing season and produce flowering stems during the second year. Natural reseeding may allow new plants to establish in suitable conditions.
• WHERE CAN I GROW EVENING PRIMROSE? Evening Primrose is suitable for pollinator gardens, wildflower meadows, sunny borders, naturalized landscapes, and reclamation plantings. Its tall, branching growth habit adds height and bright yellow color to outdoor garden spaces.
• WHAT SOIL AND CARE DOES EVENING PRIMROSE NEED? Evening Primrose grows in full sun and well-drained soil, including poor or sandy conditions. Water regularly while seedlings establish. Once mature, plants tolerate periods of drought. Avoid excessive fertilizer or overly rich soil, which can encourage leafy growth.
