Koyuki
‘Koyuki’ is a very original Japanese maple, appreciated for its netted variegation: at budbreak, it looks like a snowflake drawn by darker veins over a white to cream background. In summer, the foliage turns light green, then autumn colours in orange-yellow. A luminous cultivar, superb in a container or a small garden, best placed in bright partial shade to preserve foliage quality.
Character & interest
The charm of ‘Koyuki’ comes from its spring foliage: young leaves can be very pale (white/cream) with a structure highlighted by darker veins, creating a delicate “snowflake” effect. The colour then settles into a softer green, before shifting to warm tones in autumn.
Colours
-
Spring : white/cream leaves with darker veins (“snowflake” look), sometimes with a very pale green base.
-
Summer : light green.
-
Autumn : orange-yellow (often very luminous).
Habit & vigour
Rather upright habit, moderate growth.
Indicative size
As a guide: around 2 m tall and wide at about 10 years in several descriptions, with a potential around 4 m ultimately in the ground depending on conditions (climate, soil, training).
Exposure
Gentle sun / bright partial shade. Protection from hot afternoon sun is recommended—especially in a dry climate or in a container—to limit scorching on the very pale young foliage.
