Cascadia Maple

Cascadia Maple (Acer x pseudosieboldianum 'Cascadia')

Cascadia Maple (Acer x pseudosieboldianum 'Cascadia') is a cold-hardy ornamental maple that delivers the refined, deeply lobed foliage look many people love in Japanese maples, with added toughness for colder climates. It forms a graceful, compact canopy that fits easily into residential landscapes, bringing a layered, garden-forward feel to entries, patios, and mixed borders. Through the growing season the foliage stays a clean green, creating a calm backdrop for flowering shrubs and perennials, then finishes with strong fall color that can shift into warm oranges and reds. If you want an easy focal point tree that adds texture and seasonal change without needing a large footprint, Cascadia Maple is an excellent choice.

Distinctive Features

The leaves are deeply cut and finely textured, creating an airy, elegant canopy that looks intentional in both classic and modern designs. Branching tends to be attractive and well-structured, giving the tree a sculptural look even when it is bare. Fall color is a major highlight, often developing rich warm tones that stand out against evergreens and late-season gardens. Because this type is bred for improved hardiness, it is a strong option when you want a Japanese maple style look but need a plant that handles winter and variable conditions with more confidence.

Growing Conditions

• Sun: Full sun to part shade; afternoon shade is helpful in hotter sites, while more sun improves fall color.
• Soil: Moist, well-drained, organic-rich soil; slightly acidic to neutral is ideal.
• Water: Moderate; keep evenly moist during establishment and water during extended dry spells.
• USDA Hardiness Zones: 4 to 7.
• Habit: Deciduous small tree with a rounded to vase-shaped habit and refined branching.
• Mature Size: About 10 to 15 feet tall and 10 to 15 feet wide.

Ideal Uses

• Focal Point: Use as a small specimen where foliage texture and fall color can take center stage.
• Front Yard and Entry Planting: Add a refined, garden-forward look near doors, walkways, and windows.
• Mixed Border Accent: Anchor a layered planting with a light canopy that pairs well with shrubs and perennials.
• Courtyard and Small Gardens: Fits tight spaces where you want an ornamental tree without overwhelming the design.
• Evergreen Contrast Planting: Pair with dark conifers or hedges to make foliage texture and fall color stand out.

Low Maintenance Care

• Watering: Water deeply during the first one to two seasons; consistent moisture helps establish a strong root system.
• Mulching: Apply a 2 to 3 inch mulch layer over the root zone to conserve moisture and protect roots, keeping mulch off the trunk.
• Pruning: Prune lightly in late winter to remove crossing branches and refine structure; avoid heavy pruning.
• Fertilizing: Feed lightly in spring if growth is slow; rich soil and mulch often provide enough support.
• Site Selection: Shelter from harsh wind and avoid droughty, compacted sites to keep foliage looking clean through summer.
