About
Acer japonicum 'Attaryi' is a robust, upright deciduous shrub that can grow up to 12 meters tall. Its foliage consists of large, 7 to 9 lobed leaves that are finely dissected and deep green, with division extending nearly to the base of each leaf. In the fall, the leaves transform into vivid shades of purple-scarlet and flame-red. During spring, the tree produces small, purple-red flowers in subtle clusters, which are succeeded by winged fruits that are tinged with red.
