Evening Primrose

Evening primrose is a family of flowers native to North and South America. They come in annual, perennial and biennial forms. Many are yellow in color and only open their bloom for less then a minute in the evening. This is how they got their name but it is not true for all of the evening primrose family. Evening primrose is most easily identifiable by its stigma which has four branches which appear like a cross in the center of the flower. This evening primrose was photographed in Texas.
