Slow growing small tree, often multi-stemmed. Attractive palmate, fan-shaped leaves with 9 to 11 lobes. They are soft golden yellow flushed with orange-red, becoming more greenish yellow in summer. Very good autumn colours. Reputed to be stronger growing and more resilient than its parent 'Aureum'.
Moist, well drained, fertile soil in part shade. Will tolerate full sun in locations that are not too hot. Needs a position sheltered from cold winds and late frosts, which can damage emerging foliage.
Prune if required, by removing dead or unwanted branches in late autumn to midwinter.
By grafting in late winter, or bud-grafts in late summer. Slow and tricky to propagate.
Originated as a sport of Acer shirasawanum 'Aureum', raised at the Maplewood Nursery, Oregon the USA
