Characteristics of Katsura Tree (Cercidiphyllum japonicum) in the Wild

Cercidiphyllum japonicum
Katsura (Cercidiphyllum japonicum) is a species of deciduous tree in the Cercidiphyllaceae family native to China and Japan.

This species is listed as an endangered species in China, but in total the Japanese population, Cercidiphyllum japonicum is classified as a lower risk.

The Chinese katsura tree was distinguished in the past and was named as Cercidiphyllum japonicum var. sinense, but is now considered the same species as Cercidiphyllum japonicum.

Today katsura is cultivated and widely grown as an ornamental tree in Japan and elsewhere with suitable climates. Apart from being a complement to the landscape, the katsura tree is also cultivated for its valuable wood for construction and woodworking.

There are several cultivars of katsura that are suitable for growing ornamental trees, including:


    Cercidiphyllum japonicum ‘Aureum’
    Cercidiphyllum japonicum ‘Heronswood Globe’
    Cercidiphyllum japonicum ‘Ruby’

 
Three cultivars have even received the Royal Horticultural Society’s Award of Garden Merit in 2017, namely:


    Cercidiphyllum japonicum
    Cercidiphyllum japonicum ‘Heronswood Globe’
    Cercidiphyllum japonicum f. pendulum
