Palmatifolium

Character & interest

‘Palmatifolium’ delivers the classic “full moon” look: broad, rounded leaves, a soft texture, and—over time—the silhouette of a small tree. Its main appeal is its generous green foliage (very readable in a border) and an end of season often rich in warm tones. It’s also a good choice if you’re looking for a green shirasawanum that is less delicate than some very yellow forms.

Colours

• Spring : soft green to yellow-green, sometimes with pink/bronze nuances on young leaves or along the edge (variable with conditions).

• Summer : green (often deeper green in mid-season).

• Autumn : yellow, then orange and red; purple tones may appear depending on climate.

Habit & vigour

: yellow, then orange and red; purple tones may appear depending on climate.

Indicative size

Observed orders of magnitude depending on sources and training:

• around 2–3 m in the medium term (depending on cultivation),

• with possible development towards 4–5 m in the ground,

• spread often becomes substantial with age and may approach the height in favourable conditions.

Exposure

Bright partial shade, or sun if the soil stays cool. ‘Palmatifolium’ is often cited as more sun-tolerant than other Acer shirasawanum, but protection from scorching afternoon sun is still preferable in hot climates or in containers.
