Searching through my tree books, I have come to the conclusion that my mystery tree is a Green Ash. Hardy, considered one of the best ornamental shade tree selections, twiggy branch structure, provides quick growth which I remember the landscaper said when he suggested it. Small clusters of green to reddish-purple flowers appearing early spring, think I remember that?, and in mid summer dense cluster of green to tan fruits. These clusters are more reddish-brown? Provides wildlife habitat and that is probably what sold me on it. It's a nice little tree. I like it.
Now, grabbing my supplies and off to "summer art".
