Common characteristics:

Korean maple is a deciduous, small tree or large shrub. Leaves are medium to dark green leaves that are 5” in length and consist of 9-11 doubly serrate lobes. The leaves turn beautiful shades of yellow, orange, and red in fall. Purple flowers bloom in spring. The flowers are followed by winged samaras. 

The name "pseudosieboldianum" is in reference to the species "Acer sieboldianium", or rather the idea that the Korean maple may be seen as a "false Siebold's maple". In colder climates, Korean maple may serve as a substitute for the popular Japanese maple (Acer palmatum). Korean maple has similar decorative qualities as Japanese maple but boasts a higher degree of hardiness.
