Tufted Evening Primrose

Oenothera caespitosa

Honeybees visit tufted evening primrose primarily for its pollen, with moderate nectar accessible in the morning after evening opening; large bees can effect pollination while smaller ones often steal pollen. Peak bloom spans April to August, providing a steady supply during late spring and summer. It forms basal rosettes requiring well-drained soil and full sun, and may be browsed by deer in some areas.
