Ternstroemia gymnanthera Cleyera, Japanese Ternstroemia1

Edward F. Gilman2

Introduction

The dense, unusually dark green foliage takes on various shades of red depending upon the season and exposure but always remains shining and evergreen (Fig. 1). The small, white, fragrant flowers are borne in clusters at the leaf axils and are followed by yellow to dark red fruits, eventually splitting open to reveal shiny, black seeds which persist through the winter.

Use and Management

Cleyera is tolerant of full sun but grows best in partial shade in rich, moisture-retentive but well-drained, acid soil. The leaves will turn yellow if the soil is alkaline. Pruning is not usually necessary on slow-growing cleyera, but new growth may be pinched to encourage compactness, particularly in the shade. The clean, neat, upright growth of cleyera makes it a good choice as an accent plant as well as a screen or hedge. Plant on three- to five-foot centers to form a hedge of mass planting. Cleyera makes a good background plant for a shrub border that acts as a screen or wind break.

Propagation is by seed or cuttings.

Pests and Disease

Pest problems are rare on cleyera with scale being the only one of occasional significance.
No diseases are of major concern.
