Flowers in Either Frankfurt or Mainz, Germany

One thing that captivated me about Europe was the presence of greenery and flowers in every conceivable place. This appears to be a temporary construction shelter set up outside stores, and it has been topped with boxes of bright geraniums. But I'm not sure where it was. I think it was Frankfurt-am-Main, but it could well have been Mainz, since they and Wiesbaden all ran together so that I never knew for sure where I was.
