You are blessed. All of the ashes in our area have been destroyed by the Emerald Ash Borer. It wouldn't be long now until the Green Ashes burst into brilliant yellow fall splendor. There used to be a grove of such trees surrounding the now abandoned offices of Golden Rule Insurance which I could see from the highway on my way to/from work. But no more. And my neighbor across the street had a big Green Ash (which didn't color so well), but she had to take it down last year after the borers killed it.
So now we wait upon the Locusts to color (golden yellow) with their multitudes of tiny leaves.
And then Cottonwoods, the Oaks and the Sycamores, and finally, the glorious Maples. We would get a nice orange-red show in our front yard, but our Sugar Maple is struggling now for some reason.
I am a great fan of Autumn for it's color (and Spring, as well), as I remember walking to school through the swaths of leaves which had dropped from the trees like snow. The tree I remember most fondly was a Yellow Poplar (Tulip Tree) down the street. I loved its margarine yellow and chocolate brown leaves in the Fall.
Aside from the Sugar Maple, I have Birches in the back, with papery thin bark in shades of creamy-white to cinnamon.
Also, I just planted (this year) a Beech with creamy-pink edging on it's leaves. I love the smooth bark of the Beeches, and the coppery brown of their leaves in the Fall. To round out the landscape, I have a couple Colorado Blue Spruce as well as a few discreetly placed flowering trees (Dogwood, Redbud, Smokebush, etc.).
Although I love the look of Eastern White Pine, I was afraid that my property couldn't accommodate a tree of that eventual size, so I settled for plantings of Dwarf Mugo Pine.
