At least, I think that's it's name. It's the one with fragrant whiteish-pink snowballs in early Summer. There are three planted in an outside corner, 20 years old and we've hacked them back to the ground twice. In two years, they are six feet tall again. Does anyone know if this shrub can be trained to tree-form? I mean if I take off all but ONE main wood right down to the crown, wouldn't that work? I guess I don't even care if they die. When is the best time of year to prune them into a tree, if it's at all possible?
