Anyone who lives in my general area (Ohio, Kentucky, Michigan, West Virginia, etc.) should know what I'm talking about. What specific evergreen tree grows on the roadside rocky hillsides that have been dynamited to make way for the road? They pretty much grow straight up, like a tower. The shape is similar to a Moon Glow Juniper, but it's a much darker shade of green, and gets much taller: They seem to be a good candidate for poor soil conditions, which is my primary concern. Something that grows straight up without much "spread" would also be ideal, since it will be planted somewhat close to a wall. Any help is appreciated.
