Opinion

Michael’s Opinion- A cross between Acer rubrum and Acer saccharinum. It is a tree that is very worthy of planting in urban areas or lining the streets. It has fantastic orange and red autumn colours that will never disappoint. It is a fast growing tree that is very adaptable to dry or wet conditions.
