Acer palmatum x shirasawanum ‘Green River' Weeping Japanese Maple

'Green River' is a weeping laceleaf hybrid between Acer palmatum and Acer shirasawanum, selected by Talon Buchholz for its cascading habit and late spring leaf-out, which helps it avoid late frost damage. The foliage displays the full-moon parentage's rounded leaf form combined with delicate lacinate margins; leaves emerge bronze-green and transition to bright golden yellow in autumn. Growth is heavily pendulous, reaching approximately 3-4 feet in height and width over ten years. This cultivar benefits from afternoon shade, particularly in warmer climates.
