Paulownia Trees

I got a special request to identify these trees from a previous post. Thanks to Ask-A-Gardener Service at the Pennsylvania Horticultural Society I have discovered that these trees are Paulowina Trees. I admire their spring blooms as well as their ability to grow almost anywhere. Below are photos of a Paulowina tree growing out of the side of a building.





These are images from my original post about the trees.
