Cleyera japonica growth rate

Cleyera japonica ( Japanese Cleyera )
Also called Ternstroemia gymnanthera. An evergreen upright-oval shrub to medium-sized tree, that is native to Japan, Korea and nearby parts of China. Reaching up to 15 x 10 ( rarely over ) 10 feet in 10 years, the largest on record is 40 x 22 feet with a trunk diameter of 1 foot. The Japanese Cleyera is moderate to fast growing on ideal sites ( fastest recorded growth rate being 3.5 feet ).
The leathery foliage is similar to that of its relative the Camellia. The toothed, oblong or elliptical leaves are up to 4 x 1.5 inches ( rarely to 6 x 2 inches ) in size. The foliage is deep red at first during spring turning to glossy deep green then to burgundy during fall & winter. They are generally tufted or clustered at the ends of the branches.
The small, fragrant, 0.6 inch wide, bell-shaped, pendulous, white flowers are borne in sprays on 2nd year wood during late spring.
They are followed by small black olive like drupes.
The smooth bark is pale gray.
Heat tolerant, the Japanese Cleyera prefers cool, moist, light, slightly acidic, well drained soil. It is also prefers being sheltered from strong winds and hot sun. Tolerant of clay, drought, salt and any exposure from sun to shade. Rarely bothered by insects or disease. Foliage can turn yellow from chlorosis on excessively alkaline soil. Fertilize in early spring and prune and shape after blooming. Propagation is from seed and half hardened cuttings. Hardy zones 6 to 10 ( tolerating to 0 F, damaged at -3 and killed at -6 F ) and heat tolerant.
Cercospora leaf spot can be a problem however most of the cultivars are only lightly prone in comparison to the species with Leann showing high resistance.

JAPANESE CLEYERA

Large, slow-growing, carefree shrub to 10 feet tall, 6 feet wide (easily kept smaller through pruning). Good substitute for the overused and disease-prone Fraser photinia (Photinia x fraseri). Often confused with true Japanese cleyera (Cleyera japonica), page 246.

Glossy, leathery, rounded oval to narrowly oval leaves are 1123 inches long, borne on red leafstalks; they are bronzy red when new, maturing to deep green, bronzy green, or purplish red depending on season, exposure, and the particular plant. Red tints are deeper in cold weather. Summer flowers are 12 inches wide, creamy yellow, fragrant but not showy. Fruit resembles little red-orange holly berries.

Grow in moist, well-drained, acid soil. Tip-pinch to encourage compact growth. Use as basic landscaping shrub, informal hedge, foundation plant, poolside plant. Good companion for camellias (to which it is related), azaleas, nandina, pieris, ferns. Cut foliage keeps well.

Several interesting selections are available. ‘Bigfoot’ has large, glossy, light green leaves and a notably upright habit; it grows quickly to 1214 feet tall and only 56 feet wide. ‘Bronze Beauty’ has bronze new growth and reddish bronze fall color. ‘Burnished Gold’ produces bright golden new growth that gradually fades to bronzy green. ‘LeAnn’ has glossy, orange-red new growth that matures to deep green. ‘Variegata’ has dark green leaves with a creamy yellow edge that turns pink in winter.

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.

Cleyera Shrubs

Cleyera (Ternstroemia gymnanthera) stands out among other evergreen shrubs with its colorful, glossy foliage. Sometimes sold under the name Cleyera japonica, it grows in U.S. Department of Agriculture plant hardiness zones 8 through 10, where it serves several roles. Cleyera provides year-round interest and demands little care, but you should understand its needs and traits before you plant one.

It’s a Looker

Reaching 8 to 10 feet tall with a 6-foot spread, cleyera makes an assertive addition to the yard. It is clad in dense masses of glossy, evergreen leaves, which change color from red to green during the growing season. Tiny white flowers emerge in spring and are replaced by 1-inch-long oval berries. Cultivars, such as Bronze Beauty (Cleyera japonica “Conthery”) differ slightly in appearance, producing bronze-colored new foliage that matures to solid green. Its dimensions are roughly the same as standard cleyera shrubs, but it is slightly more cold-tolerant and will grow in USDA zones 7 through 10.

Versatile Cleyera

Cleyera’s dense, upright growth habit make it a good choice for hedging, but it also works well as a stand-alone specimen plant due to its attractive vase shape and showy foliage. Because it responds well to pruning, a cleyera shrub can also be pruned into a standard or a multitrunked tree to show its graceful structure. Cleyera shrubs used for a hedge or screen should be planted 3 to 6 feet apart on a staggered line to maximize their foliage coverage while allowing them plenty of room to spread their roots. Those pruned into a tree form should be planted well away from driveways and streets because their low-growing canopies may catch on or block taller vehicles.

Cleyera Care

Hardy and adaptable, cleyera will grow better and live longer if planted in the right conditions. A lightly shaded, fast-draining site with acidic soil provides the best environment for growing cleyera, although it will tolerate full sun in cooler climates. Don’t plant it in alkaline soil because it will increase the chances of chlorosis, an iron deficiency that causes yellowed foliage and slow growth. Also, avoid planting it under a deciduous tree that casts heavy shade because it may suffer leaf burn when exposed to winter sunshine after the tree loses its leaves.

Keeping It Healthy

Once established in a suitable site, a cleyera seldom needs hands-on care or maintenance. It generally doesn’t have issues with pests or diseases. Water it weekly to a depth of 1 inch during the summer, especially in warmer climates or during times of extreme drought. Stop watering in winter or during rainy weather. Routine feeding is not necessary, although a 3-inch layer of compost spread beneath the drip line of the shrub will provide a constant, low-level source of nutrients while keeping weeds at bay. Cleyera grows slowly and seldom needs pruning, but you can pinch it back in spring to encourage a more compact shape.
