Francine, is there enough interest to fill a box do you think? if so, we'd better get moving...
I'll commit to 3... fragrant is good, pink or white preferable... 'Mohawk' is gorgeous. I already have V. tomentosum 'Shasta' and a V prunifolium (blackhaw viburnum) but am open to any other suggestions.
I just came across this article suggesting particular varieties for fragrance, fruit, or other characteristics:

John, maybe you could eyeball that list and pick out some of your particular faves for consideration?
