Iijima Sunago Japanese Maple

Iijima Sunago Japanese Maple (Acer palmatum 'Iijima Sunago')

Iijima Sunago Japanese Maple (Acer palmatum 'Iijima Sunago') is a unique and underappreciated cultivar admired for its rich, mottled foliage and strong seasonal transitions. Its deeply lobed leaves emerge in spring as a deep purple-red speckled with green and bronze�an effect known as �sunago,� referring to scattered grains of sand. The foliage darkens in summer before exploding into a fiery mix of orange, scarlet, and gold in fall. With a graceful, upright form and dense canopy, this tree brings four-season beauty and subtle complexity to refined landscapes.

Distinctive Features

'Iijima Sunago' is best known for its unusual speckled foliage�an effect not often found in Japanese maples. Leaves are medium-sized and palmate, with a strong purple undertone mottled by green in spring. As summer arrives, the foliage deepens to burgundy, providing a dark backdrop in the garden. In autumn, the tree transforms with a vivid tapestry of warm tones. Mature specimens typically reach 10 to 12 feet tall and 6 to 8 feet wide, forming a broad, upright vase shape that fits well into borders, woodland edges, or small focal areas.
