Cascadia Maple

Cascadia Maple (Acer � pseudosieboldianum 'Cascadia')

Cascadia Maple (Acer � pseudosieboldianum 'Cascadia') is a cold-hardy hybrid maple that delivers the grace and beauty of a Japanese maple with the resilience required for colder regions. Bred from Acer pseudosieboldianum and Acer palmatum, this cultivar combines finely dissected foliage with brilliant seasonal color and improved adaptability. Its deeply cut, soft green leaves transition to vibrant shades of red, orange, and gold in fall, offering dynamic interest throughout the growing season. Compact, durable, and ornamental, Cascadia is an ideal choice for focal point plantings in USDA Zones 4 and up.

Distinctive Features

'Cascadia' features deeply lobed, fern-like foliage with a refined texture and cascading habit. The leaves emerge bright green in spring, retain their softness through summer, and erupt into a display of warm autumn tones as the seasons change. Unlike traditional Japanese maples, Cascadia withstands harsh winters without dieback, while maintaining an elegant form. It typically grows to 10 to 15 feet tall and wide, forming a rounded silhouette ideal for smaller gardens or woodland borders.
