I've fiddled around with this bed. It's planted with fothergilla, dwarf itea and clethra, and New Jersey tea. Each shrub has fuzzy white flowers, some of the fragrant and all of them attractive to nectaring insects. Something is in bloom here through most of the season. I let violets grow up under them which looked lovely while they were in bloom and like crap later on. I've weeded them all out again but that will probably be an ongoing task.
