I have an unsightly garage across the bottom of my garden. I am wanting to plant some trees that will grow slightly higher than the garage (about 10-12ft). Someone suggested flowering cherry trees but because I need to plant four to perhaps get two with green leaves and two with red leaves. I don't seem to be able to find the names of any trees (especially red leaves) that only grow to that height. Can anyone on the gardeners forum help me please, or if you have any ideas on other trees I would be most grateful.
