About
Acer palmatum 'Beni-kawa' is a small deciduous tree that typically reaches heights of 3 to 4 meters. It shares similarities with the well-known 'Sango Kaku,' featuring robust coral-red stems during the winter months. The tree showcases 5-lobed leaves that emerge with a pinkish-yellow hue, transition to green in the summer, and turn yellow in the fall. In spring, it produces small reddish flowers, followed by winged fruits in autumn.
