About

Acer amamiense is a deciduous tree that typically reaches heights of 6 to 7 meters. It features broad, heart-shaped leaves with five lobes. In early spring, before the foliage emerges, it produces yellow flowers, which are succeeded by brownish, winged fruits on female specimens, all of which are adorned with whitish hairs.
