O taki
‘O taki’ is an Acer japonicum (full moon maple) prized for its large leaves and, above all, for its very intense autumn colour, often bright red to red-orange. In spring, the foliage opens green (sometimes with a reddish tint on young shoots depending on conditions), then stays green in summer before the flamboyant finale. An excellent choice as a focal point in the garden, and a superb variety for a large container.
Character & interest
‘O taki’ brings that classic “full moon” presence: bold foliage, a small-tree silhouette, and an end of season that can be seen from afar. It’s an excellent choice if you like Japanese maples that are green in summer but finish with a particularly strong red autumn display. In spring, it can also show a more nuanced look on the very youngest leaves (depending on climate and exposure), adding an extra seasonal highlight.
Colours
-
Spring : green at budbreak, sometimes with a reddish tint on young leaves/shoots depending on conditions.
-
Summer : green to lighter green (fully settled foliage).
-
Autumn : bright red (often very vivid), with possible red-orange nuances.
Habit & vigour
Large shrub / small tree habit, fairly upright at first then more rounded with age. Good vigour for an Acer japonicum: steady growth if the soil stays cool in summer.
Indicative size
Observed orders of magnitude depending on sources and training:
-
often around 2.5 to 3.5 m tall at about 10 years,
-
with about 1.5 to 2.5 m spread at that age (depending on training and conditions),
-
in the very long term, it can develop into a broader small tree when planted in the ground.
Exposure
Gentle sun / bright partial shade. To support growth and foliage quality, a sheltered spot away from drying winds and scorching afternoon sun is recommended.
