As its name suggests, Acer palmatum ‘Coonara Pygmy’ is a compact dwarf Japanese maple that grows to around 2 metres in height. Its naturally small stature makes it one of the best Japanese maples for pots, small gardens, and bonsai projects.
But the appeal of this variety goes far beyond its size. The foliage is a seasonal display of colour. In spring, leaves emerge a soft pink flushed with green. As the months warm, the foliage deepens to a mid-green. Come autumn, the tree transforms again, this time into brilliant shades of red, orange, and sometimes yellow—though final autumn hues will vary with your climate.
Landscaping uses.
‘Coonara Pygmy’ is a wonderful feature plant, especially in part-shaded borders or tucked into courtyard containers. It’s also a top pick for bonsai enthusiasts looking for a dwarf cultivar with impressive seasonal colour.
For added effect, underplant it with ornamental grasses. Try Liriope muscari ‘Emerald Cascade’, dwarf mondo grass, or Japanese temple grass to complement its form and colour.

Soil / Potting Mix
This maple prefers humus-rich, well-drained soil. For potted specimens, use a high-quality potting mix blended with compost and some fine pine bark to improve drainage. Aim for a slightly acidic to neutral pH.
Mulch around the base of in-ground plants to keep roots cool and moist, especially during hot summers.
Sun / Light
Plant Acer palmatum ‘Coonara Pygmy’ where it receives morning sun and afternoon shade. While it tolerates full sun in cooler regions, in warmer climates, it benefits from dappled light or filtered shade to prevent leaf scorch.
Temperature Range
This variety is hardy to moderate frosts and performs best in temperate climates. Ideal temperatures range from -5°C to 30°C (23°F to 86°F). In extreme heat, leaf edges may burn without adequate moisture and protection from hot afternoon sun.

Fertiliser
