Evening Primrose

 Evening Primrose is one of the flowers that opens at night. During the mid-day you will probably only see faded, ragged, and closed flowers ,along with unopened buds. By evening, if patient .... you will see the new buds open. A nature writer named Mrs. William Star Dana said that they open for a longer period time in the fall, and she thought it had to do with the sun not being as strong at that time of year. Moths pollinate this lemony smelling flower and moths have been known to just cuddle up inside the primrose flower as it is closing for the day, and sleep in its delicate tent.
