Yellow Evening Primrose

These yellow evening primroses were growing this summer along the edges of Boggy Creek at the Condie Nature Refuge.

This prairie wildflower is biennial, with a rosette of leaves forming the first year, and a tall leafy stem the second. (Jennings). The bright yellow flowers of this primrose apparently open in the evening and fade during the morning. These pictures were taken late morning, so they have some staying power...
