Drove around Metroit Detroit today and noticed many trees which bloomed with white flowers very reminiscent of Cherry Blossom Trees but different. My father-in-law has two such trees in front of his house. When I stopped by today I parked right under these two trees. When I got out of my car I got a whiff of a smell that was so bad that I almost gagged. My little nephew was on the porch. When I asked him what was the smell, he replied that it was coming from the flowers on the trees.

After leaving, I noticed these trees all over the neighborhood and while driving in Southfield along Civic Center Drive I noticed these trees lining the entire stretch of the street from Evergreen to Telegraph. While waiting at traffic lights and with my sunroof open, I could smell that awful smell coming through the windows. What kind of tree is this? I didn't notice these white flowers on the trees last year. Anybody else notice the pretty flowers with the awful smell?
