Special Attributes

Of all the Japanese Maples growing in our gardens, 'Osakazuki', one of the oldest and fastest growing Japanese maple cultivars, has the most brilliant red fall foliage color. As the temperatures begin to cool in fall, its large, 7-lobed, bright green summer leaves become flushed with red, then suddenly turning to the most vibrant, glowing crimson red you've ever seen on any Japanese maple. The branches of Osakazuki form an absolutely beautiful vase-shape tree with a rounded crown that reaches 15-18 feet tall in the first 10 years and up to 25 feet at maturity.
