What Does a Japanese Holly Look Like?

Japanese Holly Varieties

Japanese holly is a handsome broadleaf evergreen shrub.

It’s slow-growing, fine textured, and comes in more than 500 cultivated varieties. Sometimes referred to as the box leaf holly because it resembles a boxwood, the Japanese holly actually has darker, more lustrous foliage than boxwood and is less prone to insects and diseases.

Japanese holly leaves are egg-shaped and arranged alternatively on the plant’s stems. When both male and female plants are present, small, round, purple-black fruits will appear.

Though it prefers sun and light, moist, acidic soil, Japanese holly is tolerant of shade, drought, and urban conditions.

Japanese Holly Facts

The Japanese holly is a native of Japan and East Asia, usually found in woods and wetter lowlands and mountains all over Japan. Today it is one of the most popular landscape plants in the U.S.

Potential Threats

The Japanese holly is quite easy to care for, but there are a couple of pests and diseases this wonderful hedge may encounter.

Southern red mites are Japanese holly pests that usually attack in spring and fall. They feed on the undersides of leaves. Symptoms of feeding include light yellow speckling on leaves. Eventually, the leaves will turn brown and then drop.

Blackroot rot disease can also impact Japanese hollies. Those with extensive root rot will usually decline and die during dry periods.

If you live where fall weather is cool and wet, Phytophthora Leaf and Twig Blight may infect the leaves and stems of Japanese holly. The disease is characterized by purple-black leaf spotting, defoliation, and the development of twig cankers. Leaf spotting frequently begins on the leaf margin and on the lower part of the plants in late fall. The disease progresses up the shrub during winter. Twigs dieback and cankers develop on larger stems later in winter.

A certified arborist can help you gain control of southern red mites and check for black root rot disease on your Japanese hollies.
