Last Tuesday was a perfect day to be walking up Madison Avenue. The morning was crisp and bright. I passed a corner market. A crowd of cut flowers in buckets edged the front of the store. It's still too cold for flowers to be outside, so a sort of enclosed porch made from clear plastic protected the tulips, gerbera daisies and irises. The bumpy plastic reflected the blue sky and the stone buildings across the street. The reflections mixed with the flowers just beyond the plastic. What an amazing sight, a muddle of color, encapsulating one moment on the edge of spring.
