About

Acer heldreichii var. macropterum is a deciduous tree that typically reaches heights of 10 to 15 meters. Its bark ranges from grey to pale brown, providing a subtle backdrop for its unique foliage. The leaves are deeply lobed, showcasing three distinct lobes, and measure approximately 15 cm in both length and width. In autumn, the foliage transitions to hues of yellow and brown. During spring, clusters of yellow flowers emerge, later giving way to substantial yellow-brown winged fruits that appear in the fall.
