Dogwood blossoms

The National Arboretum is bounded on one side by the Anacostia River. The ebb and flow of of the flowers, plants, and trees in the Arboretum is a rhythm fed in part by that river. Here, dogwood blossoms from last spring, rich in contrast as their tips begin to brown, are now gone, long since fallen, adding their substance to the earth, feeding the next generation.
