Korean Maple

Korean maple is a deciduous small tree or large shrub with finely lobed green leaves, purple spring flowers, and bright fall color. Native to Korea and China, it offers Japanese-maple-like foliage in a species rated hardy to USDA zones 4–8. ## Landscape use and size The University of Minnesota lists a mature height and spread of 15–25 ft. Use it as an ornamental or shade tree in a lawn, park, or garden with room for a broad crown. ## Seasonal interest Leaves are medium to dark green through summer, then turn yellow, orange, and red in fall. Purple flowers bloom in spring and are followed by winged samaras. ## Siting and soil Plant in full sun or bright, dappled light in moist, organically rich, well-drained soil. Avoid hot, dry exposures and choose a site sheltered from strong winds. The [University of Minnesota UFOR profile](https://trees.umn.edu/korean-maple-acer-pseudosieboldianum) describes the species’ range, seasonal traits, and siting; the [Denver Botanic Gardens record](https://navigate.botanicgardens.org/weboi/oecgi2.exe/INET_ECM_DispPl?NAMENUM=18318) independently confirms its identity, purple flowers, and sun and soil conditions. ## Maintenance Keep soil evenly moist while the tree establishes and during extended dry spells. Avoid routine heavy pruning; inspect for damaged or crossing branches and make selective structural cuts as needed.
