The mid-green foliage, which unfolds reddish purple in spring and turns glowing shades of yellow and apricot in fall, is a real feature of this beautiful tree from the woodlands of China and Japan. Fast growing, the Katsura quickly develops into a specimen tree with rounded, heart-shaped leaves similar to those of Cercis (Redbud). Â Although not aromatic, the fallen autumn leaves have been varyingly described as smelling of cinnamon, burnt sugar, or ripe apples. Â Tiny flowers (red on male trees and green on female trees) appear in the spring.
