Facts

Katsura-tree is a large (up to 60 feet or 20 m tall) tree native to the forests of Japan and China. The tree is as majestic as its namesake, the Katsura Imperial Villa, a triumph of 16th-century architecture in Kyoto, Japan. Its autumn leaves turn a bright orange/apricot in fall, and give off a spicy-sweet smell when crushed.
