I don't know about "brush". Where I live (in the pacific northwest), when I pass tree farms on the highway, they look like aspens to me. Very tall and pole-like, with white bark. Tons of trees planted in very neat rows -- fun to watch them form lines as you drive by. A bit of googling gets me this: http://oregonwild.blogspot.com/2007/12/tree-farm-color.html http://oregonwild.blogspot.com/2007/12/tree-farm-color.html That's what they look like.
