Acer pseudosieboldianum x palmatum 'Hasselkus'

Acer Northern Glow

Acer pseudosieboldianum × palmatum ‘Hasselkus’ is a cold-hardy hybrid maple that blends the graceful, finely cut foliage of Japanese maples with the durability and winter toughness of Korean maple. Summer foliage is medium green with deeply divided, elegant leaves that closely resemble Acer palmatum.

In fall, ‘Hasselkus’ is outstanding, developing brilliant crimson, scarlet, orange, and burgundy tones, often rivaling the best Japanese maples for color intensity—especially in colder climates. The tree forms a rounded to slightly upright habit with attractive branching and a refined, ornamental presence.

This cultivar is prized for providing Japanese maple aesthetics in colder regions where traditional cultivars struggle.
