The Amur Maple is native to China, Manchuria and Japan. It was introduced as an ornamental into the United States about 1860. Since then horticulturists have developed several varieties with different characteristics of size, fruit and leaf color. The Amur Maple is a rather small tree with dense, finely textured foliage. It sometimes grows as a shrub. This hardy tree and its varieties typically produce very colorful fall foliage that is red to reddish purple. It is one of the very few maples that have fragrant flowers. A 5-year old specimen of the dwarf variety may be only 3 feet tall, but it may have a 5-foot crown spread.
