Please help me identify this tree. The flowers are in long clusters, unfortunately I don't have any photos of them. The photo is a tree at our previous home, it was third generation of a tree that was at my wife's childhood home. It was grown from a branch that fell off the second generation tree at her sister's house - it stuck in the ground and just started growing. We cut a branch off the original tree last fall (the house was vacant at the time) and put it in a bucket of soil. It is starting to produce leaves but we would like to find one that is a little further along. We've been to a few nurseries but haven't found anything even close. We are in the Tacoma, WA area. I was going to include more photos, but apparently you can only upload one. Thanks.
