Acer palmatum 'Omure yama'

Omure yama Japanese Maple

Acer palmatum ‘Omure yama’ is a distinctive Japanese maple valued for its upright, narrow habit and gracefully cascading side branches. Unlike most weeping maples, this cultivar grows strongly vertical, with pendulous secondary branches that create a refined, architectural silhouette.

Foliage emerges fresh green in spring, remaining clean and attractive through summer. In fall, leaves turn brilliant shades of orange, gold, and red, providing excellent seasonal color. Leaves are medium-sized with classic palmate form, enhancing the tree’s elegant structure.

‘Omure yama’ performs best in partial shade, particularly in warmer climates, and prefers well-drained, evenly moist soil. Its unusual form makes it a standout focal point even when not in leaf.
