Acer × pseudosieboldianum 'Cascadia'

Latin name
Acer × pseudosieboldianum 'Cascadia'
Common name
Korean Maple 'Cascadia'
Type
Ornamental tree
Family
Sapindaceae

Acer × pseudosieboldianum 'Cascadia', also known as the hybrid Korean maple, is a small ornamental tree prized for its elegant habit and remarkable cold hardiness. A cross between Acer palmatum and Acer pseudosieboldianum, it combines the refined beauty of Japanese maples with enhanced robustness. Its finely dissected foliage emerges soft green in spring, deepens to a richer green in summer, then bursts into vibrant orange-red hues in autumn. Its slightly spreading and graceful silhouette makes it an excellent choice for small to medium-sized gardens, either as a specimen tree or in sophisticated landscaping. Adapted to harsh climates, it offers a reliable alternative to traditional Japanese maples while maintaining a delicate, seasonal aesthetic.
