About
Acer davidii 'Karmen' is a deciduous tree that can reach a height of approximately 10 meters within two decades. It features bark with prominent white streaks and has narrow, tapered leaves that exhibit shallow lobes on young growth. Initially, the foliage appears in deep brown and bronze hues, transitioning to green during the summer, and ultimately displaying vibrant orange and yellow shades in the fall.
