Acer is a genus of trees and shrubs commonly known as maples. The genus is placed in the family Sapindaceae. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America.

Acer pseudosieboldianum commonly known as Korean Maple is an upright, deciduous, small tree or large shrub that matures over time to 4.5 to 7.5 meters tall with a similar but sometimes wider spread. It is native to forested areas in Korea and China. Medium to dark green leaves to 12.5cm long with 9 to 11 doubly serrate lobes turn excellent shades of yellow, orange and red in fall. Purple flowers bloom in corymbs in spring. Flowers are followed by winged samaras to 2.5cm long. Pseudo in the specific epithet means false in reference to the similarity of this tree to Acer sieboldianum which is native to Japan. Korean Maple is sometimes commonly called purplebloom Maple in reference to its flower colour (Acer sieboldianum flowers are yellowish green). Korean Maple is also similar in appearance to both Japanese Maple (Acer palmatum) and Fullmoon Maple (Acer japonicum).
