    The Armstrong Red Maple is a cross between Acer rubrum and Acer saccharinum and is known for its columnar habit and brilliant red to red-orange fall coloration. This species has the durability of the Silver Maple and can tolerate urban conditions. The root system is less aggressive, though, so it can be planted as a street tree.
