Photinia glabra: Red-Leaf Photinia1

Edward F. Gilman and Dennis G. Watson 2

Introduction

Widely planted for its attractive, bright-red, new leaf growth, Japanese photinia is a densely-foliated, broadleaf evergreen which grows 15 to 20 feet in height. Bright red leaves among the dark green ones afford a bit of foliage interest throughout the fall and winter in southern climates (USDA hardiness zones 8 and 9). The fragrant, four-inch-wide flower clusters appear in early spring and are followed by somewhat showy, red berries which ripen to black.

Use and Management

Often used as a hedge or dense screen, Japanese photinia can easily be trained into a multi-trunked small tree for patio or specimen use. It is occasionally sold as a standard, with all the branches originating from the top of a four- to five-foot-tall straight trunk. Photinia does not make a good clipped hedge because it will not keep foliage on the lower branches, grows too rapidly and does not branch enough. But it will form a nice tall screen. It can be used to frame a residential street by planting properly trained specimens on 10 to 15 foot centers. Although the red foliage color contrasts well in most applications, landscape designers avoid planting it against a red brick wall because it clashes with brick.

Growing best in full sun on moist, organic soils, photinia grows rapidly and is very tolerant of hard pruning.

The cultivar 'Rubens' has bright, bronze-red young leaves.

Propagation is by cuttings.

Pests

Mites, scales, aphids, and caterpillars are occasional pests but do no major damage.

Diseases

It is susceptible to fire blight and leaf spot which can cause serious defoliation. Be sure to locate plants in full day sun to help prevent these devastating diseases.
