About
Acer granatense is a deciduous, shrubby tree that typically reaches a height of around 10 meters. It features broad leaves that are 3 to 5 lobed, measuring approximately 10 cm in both length and width, and display a mid to dark green hue before transitioning to yellow in the fall. In spring, small yellow flowers appear in clusters, either before or alongside the emergence of new leaves. By autumn, these flowers give way to brown, winged fruits that have narrowly separated wings.
