Acer palmatum 'Oregon Sunset' Dwarf Japanese Maple

The Acer palmatum ‘Oregon Sunset’ is a beautiful compact, spreading Japanese Maple prized for its rich plum-coloured foliage, distinctive rounded leaves, and spectacular autumn display. Its naturally broad growth habit makes it an exceptional choice for smaller gardens where width and architectural form are desired without excessive height.

In early spring, ‘Oregon Sunset’ emerges with large, rounded leaves in rich shades of plum, burgundy, and deep red. The foliage creates a bold yet refined presence in the garden, complemented by a branching structure that grows predominantly outward with a gentle upright tendency.

As the tree matures, it develops into a beautifully balanced, low and spreading specimen, becoming noticeably wider than it is tall. This characteristic makes ‘Oregon Sunset’ particularly well suited to courtyards, smaller gardens, feature beds, and areas where a traditional taller Japanese Maple may eventually become too large.

Autumn is where this cultivar truly lives up to its name. As temperatures begin to cool, the foliage transforms into brilliant shades of glowing orange, scarlet, and fiery red, creating the appearance of a dramatic sunset across the canopy.

With its compact mature size, broad architectural habit, large palmate leaves, and exceptional seasonal colour, ‘Oregon Sunset’ is an outstanding Japanese Maple for both collectors and gardeners looking for a striking feature tree that remains manageable over time.

Care Information:

Climate Adaptability: Thrives in temperate climates and performs well in many South African regions with moderate conditions. Protect from extreme heat, drying winds, and intense summer conditions to maintain the best foliage quality.

Sun Exposure: Prefers morning sun with afternoon shade or bright filtered light. Protection from harsh afternoon sun is particularly beneficial in hotter regions and helps prevent leaf scorch.

Watering: Keep the soil consistently moist but well-drained, especially during warm weather and while the tree is establishing. Avoid allowing the root zone to dry out completely or remain waterlogged.

Soil Type: Prefers fertile, slightly acidic, well-draining soil enriched with organic matter. Good drainage is essential for healthy root development.

Pruning: Requires minimal pruning. Its natural lateral branching creates an attractive spreading form. Light structural pruning can be carried out during winter dormancy if required to maintain shape.

Fertilisation: Apply a balanced, slow-release fertiliser in early spring as new growth begins. Avoid excessive fertilisation, particularly with high-nitrogen products.

Mature Size: Compact, spreading form reaching approximately 2–2.2 metres high and up to 3 metres wide over 20 years, depending on growing conditions.
