Acer palmatum Osakazuki is a cultivar named for the octagonal cup used in sake ceremonies, a reference whose elegance matches the tree's character. Growing 15 to 24 feet in zones 5 to 8 with a broadly spreading habit, it spends the growing season as a pleasant, unremarkable green maple — and then, in autumn, delivers what many consider the finest red colouration in the entire Japanese Maple catalogue: a pure, uniform scarlet that spreads evenly across the leaf surface without the blotching or inconsistency affecting other cultivars.

It is more drought tolerant than many Japanese Maple selections, a practical advantage for gardens that cannot provide consistently moist summer conditions. For the gardener who wants a Japanese Maple primarily for autumn performance rather than purple summer foliage or unusual leaf form, Osakazuki is the clear choice.
