As the fall pageantry of colors continues, the Autumn Spire Maple is splendid with its vibrant red color. This is an Autumn Spire Red Maple that we have planted next to our garage at home. The red color is brillant. This tree is great for spaces where you want a more narrow profile tree. The Autumn Spire will only be about 20 feet wide at maturity, and about 40 feet high.
