Red Leaf Japanese Maple (Acer plamatum 'Atropurpureum')

Japanese Maple Japanese Maples are one of the most popular landscape trees available. They are native to Japan, China, Korea, and southeast Russia where they have been cultivated for hundreds of years. A wide assortment of cultivars has been developed, exhibiting many variations in color, leaf size and shape, and overall growth form. An excellent specimen tree of Red Leaf Japanese Maple, planted in 1973, can be seen at the edge of the Arboretum's Shade Tree Collection near the top of the Tulip Poplar Trail and the Flowering Dogwood Research Collection.

This tree is particularly striking in the late summer and fall with its red to purple foliage. Red Leaf Japanese Maple grows to heights of 20-25 ft and usually exhibits a semi-hemispheric growth form. The palmately divided leaves have 5-7 deeply cut lobes with serrate leaf margins. The bright green leaves that emerge in early April, turn to reddish/purplish hues by early fall. The small, red flowers, which appear in the spring along with the emerging leaves, are borne in stalked umbels. A distinctive feature of this cultivar is that the wings of the paired fruits (samaras) diverge at an obtuse angle. Japanese Maple wood has been used for decorative veneer/plywood, furniture components, and cabinetry.
