Acer japonicum, also known as Downy Japanese Maple or Full Moon Maple, is a stunning species of maple native to Japan, southern Korea, and Nagasaki Prefecture. This deciduous tree typically grows up to 20 ft tall, with slender shoots and rounded leaves that turn a vibrant orange to dark red in autumn. Its small, dark purplish-red flowers produce paired samaras with nutlets that hang underneath its leaves. Acer japonicum is a popular choice for bonsai culture due to its adaptability to life in a pot, vigorous growth, and responsiveness to wiring and pruning techniques. This species is also suitable for a variety of styles, including informal upright and broom. As an added bonus, Acer japonicum can be leaf-pruned to reduce leaf size, increase twigginess, and improve fall color. Overall, Acer japonicum is a must-have for any maple enthusiast looking to add a touch of gorgeous Japanese beauty to their collection.
