Identify pot?

[nover18]

I wish I could recall where I got this image. Forgive me if I can't credit the original source. I saved the image in hopes of someone being able to identify the tree and more specifically the pot. Would anyone be able to identify the source and or pot?

Just a wild guess but could it be from the Longwood Gardens collection in Kennett Square, PA?
