I was driving the back roads when I glanced between houses and noticed this lavender/purple flowering plant growing in a large patch amongst the trees. They went very high up and I found them quite appealing. The top image is taken from the road and that was as wide a shot as I could get without including houses on each side. The Azalea was much bigger on the left but I needed to crop off the bricks of the house showing through. The second image was looking up the stream towards the neighbors property where you can just see the bridge shown in the bottom photo looking the opposite direction. I had to talk to three separate homeowners to get access to shoot but all were very gracious. I am leaning toward it being Grape Hyacinth but I may be wrong.

I believe the purple hanging plant is a wisteria. A grape hyacinth is a short purple early spring flower that grows from a bulb. The wisteria you photographed is beautiful! Sometimes people grow them so the flowers hang down from a pergola. I have also seen them grown as short trees, with the flowers hanging down. It is vinelike, and the vine part is thick. They can live for many years.
As soon as I read this I knew I was way off with my identification. We had grape hyacinth in our gardens many times. There are a few small tree versions around the area that I notice every year!
One other thing, Wikipedia has a very interesting article about wisteria. You might want to check it out. Thanks for the beautiful photos!
once again, three gorgeous photos
thanks Sandy!
