The common orange day lily (or ditch lily) - puts on quite a show, but for only one day.

This was a digital scanner photo.   Placing the lily on the glass served to flatten the otherwise cone-shaped flower.   At first I didn't like the effect - until I noticed how the center lines in the petals went all the way to the center of the flower.  I thought that was a clever way to achieve a leading line to the center of the photo, so I went with it.
