Acer pseudosieboldianum ssp. takesimense, commonly known as the Ulleung-do Island maple, is a rare and refined deciduous maple native to Korea’s Ulleung Island. Closely related to the Korean maple, this subspecies is prized for its exceptional cold hardiness, elegant form, and outstanding fall color, making it an excellent alternative to more temperamental Japanese maples in colder or more variable climates.
It forms a small, graceful tree typically 15–25 feet tall, with a rounded to broadly spreading canopy and finely textured branching. The leaves are delicately divided, resembling those of Acer palmatum, emerging soft green in spring with subtle reddish tones before maturing to a rich green in summer. In autumn, the foliage transforms into a brilliant display of orange, red, and crimson hues, often with remarkable intensity and consistency.
In spring, small reddish-purple flowers appear before or with the leaves, adding a subtle ornamental touch and giving way to attractive winged samaras. The bark remains smooth and gray, contributing to the tree’s winter interest.
Best grown in full sun to partial shade, Ulleung-do Island maple prefers moist, well-drained, slightly acidic soils rich in organic matter. It benefits from some protection from hot afternoon sun in warmer regions, but is notably more resilient to cold, wind, and environmental stress than many Asian maples.
With its fine texture, dependable performance, and vivid seasonal color, Acer pseudosieboldianum ssp. takesimense is a superb choice for collectors and gardeners seeking elegance and durability in a small ornamental tree.
