Smaller perennial featuring large yellow flowers that open later in the day and stay open throughout the night. Great in rock gardens and at the garden's edge. Deadheading encourages continual bloom.
Oenothera will maintain a healthy compact form in poor, well-drained soil and full sun. In more fertile soils, it tends to spread rampantly. Evening Primrose is perfect for covering gravelly banks and other areas where the soil quality is poor. Hot, dry conditions are no problem for this plant.
