Attaryi
‘Attaryi’ is a vigorous Acer japonicum, valued for its large green leaves and its flamboyant autumn colour. The foliage starts a soft, fresh green in spring, becomes a deeper green in summer, then turns in autumn into a very intense mix of orange, red and yellow. Its habit is upright and gains presence with age: an excellent choice to structure a garden while keeping a real late-season highlight.
Character & interest
‘Attaryi’ stands out for its broad foliage, typical of Acer japonicum, and for its spectacular late-season display. It is often compared to ‘Aconitifolium’: you get the “full moon maple” spirit, but with slightly larger and less deeply cut leaves, giving a fuller presence in the silhouette.
Colours
-
Spring : soft green, often very luminous.
-
Summer : dark green to deep green.
-
Autumn : fiery orange-red, often with yellow (intensity varies with climate and exposure).
Habit & vigour
Upright habit, becoming broader and more architectural with age. Good vigour: it can form a true small tree, more substantial than a small-growing palmatum.
Indicative size
Observed orders of magnitude depending on sources and training:
-
around 4 m at about 10 years is regularly indicated,
-
at maturity, sizes in the 6 to 10 m tall range for 5 to 6 m wide are sometimes reported (depending on conditions).
Exposure
Gentle sun / bright partial shade. In warm climates, light afternoon shade and a spot sheltered from drying winds help keep clean foliage and steady growth.
