About

Acer palmatum 'Azuma-murasaki' is a resilient, deciduous shrub that can reach heights of up to 6 meters. Its leaves are lobed, initially showing a dusty yellow-orange hue. As they mature, the leaves transition to a reddish-purple color with green undertones. During the summer, the foliage shifts to a richer green with a reddish tint, eventually transforming into a deep red in the fall.
