Tree/shrub (4-6' tall) with large (6"?) white bell shaped flowers?

This past summer I drove past a house that had a large shrub (or a small tree) in the yard that had extremely large (maybe 6 inches long) white bell shaped flowers. The plant was growing in the front yard of a house in a zone 5 climate. The flowers were all over the bush/tree and the plant looked pretty unique. The flowers almost looked like white lilies that faced the ground and had a bell like shape to them.



Since it was in someone's yard and I was driving by in a car I didn't get the best look at it but the flowers appeared to be white. I didn't see any other markings on the flower.



Anyone have any idea on what this may be?

Sounds like brugmansia to me.

Reply:They sound like moon flowers. Did you notice if they were really sweet smelling and what time of day it was. Moon flowers usually bloom late in the afternoon when it is cool and stay open until it begins to warm up in the morning. They have a beautiful scent. Hope this helps. I grow them in my yard.
Reply:Possible trumpet vine, clematis, or an azalea bush. People love their plants, next time stop by and ask the owner.
Reply:It might be a catalpa tree. They bloom in the summer and are pretty spectacular. There are a lot of them in my zone 5 region. The trees get huge but even when they're small they bloom profusely. I might be wrong because to me the flowers look more like orchids than lilies but you never know. Here's a link to pages and pages of pictures:
