PRINCESS TREE

Last week I was with a group of friends in City Park in Denver and we had a certified arborist with us.  He pointed out many champion and notable trees in the park.  I got online and found five pages of champion and notable trees in Denver.  This tree is just a few blocks from my place.  It's a Princess Tree.  It looks a lot like a catalpa, but it doesn't have beans and leaves are humongous.
