If my neighbors have been watching my work on this bed over the past few months, they probably suspect mental illness. The poor azaleas and spirea have been dug up, transplanted to the backyard, dug up again and hauled back to the front, then dug up again and rearranged.
At last, I think it is coming together. We added some Japanese Holly (Ilex crenata "Soft Touch") to give it some green in winter and to contrast with the cherry. Some stella d'oro, black-eyed susans, aster, and coreopsis will brighten it up in summer and fall, after the cherry and azaleas are no longer blooming.
