Mike, I think that flowering plant is a variety of Viburnum. They are mostly classified as shrubs, but some old ones become more like trees. And there are many varieties of Viburnum.
I have two Japanese snowball viburnums, and the smell of the blooms may be the finest in all nature (up there with honeysuckle).

My one doublefile viburnum does not have the wonderful smell, but it still looks good.
Ah Choo is right. I am now blowing big honkin' rolls of oak pollen off my roof, scape and walks daily. I should wear a mask, but I have grown to dislike masks for some reason.
Sorry for the drift Bill.
