Cryptomeria japonica 'Yoshino': 'Yoshino' Japanese-Cedar1

Edward F. Gilman and Dennis G. Watson 2

Introduction

This striking evergreen forms a loose, open, pyramidal shape of somewhat pendulous branches clothed with dense, short, light green to blue/green, fragrant needles. Trees reach 30 to 40 feet in height by 15 to 20 feet in width, and develop a somewhat oval canopy with age. The trunk remains straight with relatively small-diameter lateral branches. Long branches are spaced just far enough apart to allow the handsome, reddish-brown, peeling bark to be easily seen when standing next to the tree. The short needles may take on a slight bronze hue in winter but will quickly return to green in springtime. The foliage of this cultivar discolors in winter far less than the species.

Use and Management

'Yoshino' Japanese cedar makes a dramatic landscape element for an open lawn or can be used as an attractive street tree, particularly for narrow spaces. For street tree use, remove lower branches at an early age to keep the pruning scars as small as possible. It may grow too large for most residential landscapes but makes a nice specimen or 'softening' tree for a large building.

'Yoshino' Japanese cedar should be grown in full sun, sheltered from harsh winds, on well-drained, moist, acid soil. Locate it so air circulation around the tree is good, particularly during the summer, to help prevent leaf blight. It thrives best with some afternoon shade in the southern part of its range. Although plants may grow 2- to 4-feet per year when young, they will rarely require pruning if properly located in the landscape as they naturally grow into a beautiful pyramidal shape. 'Yoshino' Japanese cedar and the species are tolerant of compacted soil and probably perform well in parking lots and other tough urban sites, with some irrigation in drought.

Propagation is by cuttings from mature wood.

Pests and Diseases

No pests or diseases are of major concern but occasionally bothered by leaf blight and leaf spot, but probably less so than the species. Mites can infest the foliage.
