Last week I visited Seattle Wash. from Phila Pa. I spotted an amazing tree, knocked on the door, and was told it was a Monkey Pod tree. What exactly is that? Would one grow in Phila Pa. Also he felt his was dying as it was turning brown from the bottom up and only the very top of the tree still was green. He had people look at it but no one knew what was wrong. It was an old large tree. Any guesses?
