Atrolineare
‘Atrolineare’ is a Japanese maple with strap-like leaves (very narrow lobes), giving a graphic and elegant look. Budbreak is bright red, shifting to burgundy / purple by early summer, then becoming calmer, more greenish-purple towards the end of the season. Autumn often finishes in a vivid red. Upright, vase-shaped habit.
Character & interest
This cultivar is part of the “linearilobum” maples: long leaves with very fine lobes, creating a light texture, different from classic dissectums. It’s a good choice for a restrained scene when you want a structural plant without a heavy mass of foliage.
Colours
-
Spring : bright red (very pronounced strap-like effect).
-
Début été : burgundy / purplish brown.
-
Fin été : often a calmer greenish-purple (the red remains as a nuance).
-
Autumn : bright red (often clear and strong).
Habit & vigour
Upright, vase-shaped habit. Steady to fairly vigorous for a linearilobum.
Indicative size
Order of magnitude:
-
~2 m / 10 years (according to some European references),
-
but can reach 3–3.5 m / 10 years in favourable conditions.
Ultimately, a small tree around 3–6 m depending on soil/climate and training.
Exposure
Best effect in gentle sun or bright partial shade (but tolerates full sun). The very fine lobes can mark in hot/windy situations; a sheltered position helps keep the foliage cleaner.
