Acer palmatum, commonly known as Japanese maple, palmate maple, or smooth Japanese maple. It is a woody plant species native to Korea, Japan, China, eastern Mongolia, and southeast Russia.

It is deciduous, with the growth habit of a shrub or small tree reaching up to 33 ft and often growing in shady woodlands. It may have multiple trunks joining close to the ground. The canopy frequently takes on a dome-like form, especially when mature.

The leaves are long and wide, palmately lobed with five, seven, or nine acutely pointed lobes. The flowers are produced in small cymes, the individual flowers with five red or purple sepals and five white petals.

Even in nature, Acer palmatum displays considerable genetic variation, with seedlings from the same parent tree typically showing differences in leaf size, shape, and color. The overall form of the tree can vary from upright to weeping.
