Oenothera speciosa (Pink Evening Primrose)
This is our first evening primrose (Oenothera speciosa) of the year. Soon we will have dozens of them, lighting up the garden in the evening (as their name suggests, their flowers open in the evening). Actually, this one is in a shady spot and it seems to be fooled by that into opening a bit early, which is actually quite nice. Oenothera speciosa is an herbaceous perennial native basically to the southern half of the contiguous United States.
