DamavandPro Oenothera Biennis Seeds (Evening Primrose)

From DamavandPro, these Oenothera biennis (Evening Primrose) seeds are a simple way to introduce soft yellow flower clusters to your garden from June to September. As a biennial plant that’s described as easy to grow and maintain, it suits gardeners of all experience levels and works well across a range of soil types and climate conditions.

Sow directly outdoors in spring once the last frost has passed. For best results, place the seeds on the surface of moist, well-drained soil, then cover with a light sprinkling of soil. Germination is expected at an ideal temperature of 18–20 °C and typically takes around 2–3 weeks. Evening Primrose prefers moderately fertile, well-drained soil in full or partial sun; once flowering has finished, cutting back the plants helps encourage new growth.
