Pink Evening Primrose

Oenothera speciosa

Honeybees forage on this plant for both nectar and pollen, providing a reliable mid-season resource in its range. Peak bloom occurs from late spring through early summer, with flowers opening in the evening. It spreads rapidly via rhizomes and can become invasive in disturbed areas, requiring management to prevent overgrowth.
