Bonsai, Evergreen, Hedge/Screen, Moist Soil, Exfoliating Bark


Native to Japan, Hinoki Cypress is a slow growing evergreen conifer that grows 50 to 75 feet tall with a pyramidal habit. It features spreading branches that droop at the ends and drooping flat frondlike branchlets bearing small scale like leaves. The main branches are dense and spreading and may droop to the ground, and the sprays of foliage are held in flat planes. Dark green scale like leaves of Hinoki Cypress are borne in pairs of two unequal sizes and shapes with white markings beneath. Adult leaves are like closely overlapping scales; leaves on juvenile branchlets and young plants don't overlap and are shaped more like tiny awls or broad needles. Hinoki Cypress has an attractive, shredding, reddish-brown bark which peels off in long narrow strips on mature trees. The cones of Hinoki Cypress are small, 8 scaled, orange brown and about 1/2 inch in diameter.

Hinoki Cypress is very popular for use as accents/specimens, hedges, screens and foundation/rock garden plants.

Hinoki Cypress is one of the 75 "Great Plants for American Gardens" as chosen by the American Horticultural Society. In Japan, the wild form is one of the most important timber trees and the many cultivars are valued as ornamentals in the garden and for bonsai subjects.

Culture: Hinoki Cypress needs little pruning to develop a strong structure and is very tolerant of pruning. Upright branches tend to fork, and these should be pruned to a single branch since they will likely break at the fork in high winds or under a snow load.
