The advantages of pot culture include being able to choose differing backgrounds. A solid color would have made this photo very flat, but the soft variable hues provide a lot of depth, IMO. And in this case, the extra color enhances the pic, I think.
Had I used the same background with the same subject below, it would have been lost. I needed something that could bring out the subtle colors of the Pulsatilla and allow the plant structure to dominate, but I didn't want a solid color background. In retrospect, I think some paper with a bit more texture in it might have been better.
