Overview: The 'Yusen' seed strain was collected during a seed expedition to the Maoershan region of Heilongjiang Province of China in 1991. The selected trees were growing in a mountainous region near the North Korean border with China. This is a hardy seed strain, typically multi-stemmed, and reaches a mature height of 8-10 meters. The distinctive characteristic which sets them apart from other maples is their smooth, bright-green bark with blue-green to white stripes of varying widths forming a pattern reminiscent of a snake’s skin. The strain is named after the Chinese professor, Zhang Yusen, who guided the 1991 seed collection expedition to Northeast China.
Fruits: A samara consisting of two oval carpels lined at the base and each terminating in a broad membranous wing.
