Evening Primrose
Oenothera elata
Honeybees forage on this plant in the morning for nectar and pollen from large yellow flowers that open at dusk and close by midday. Peak bloom occurs from June through September, providing a summer resource during a potentially lean period. It thrives in moist, well-drained soils and can reach 5 feet tall, occasionally needing staking in exposed sites.
