Description

Japanese euonymus is a dense, oval, evergreen shrub or small tree commonly used as a landscape plant. It typically grows to 15 feet high, but left alone it can reach 26 feet. It can be found in forest or natural areas in mixed deciduous forests and low woodlands, but can become weedy in disturbed areas around houses and buildings. In its native Japan, it is often found on slopes, in thickets and woods, and especially near the sea. It is drought and moderately salt spray tolerant, and can withstand heavy pruning. 

The plant is in leaf year round and produces small, non-ornamental blossoms in spring and early summer. The seeds are considered probably poisonous, while the rest of the plant may be poisonous if ingested in large quantities. It tolerates full sun and heavy shade, but does best in sun-dappled conditions with some afternoon shade in hot summer climates. It is pH adaptable and salt tolerant. It will grow in most soils, including clay, but does not do well in wet conditions. It makes an excellent hedge that can tolerate heavy pruning.

Diseases and Insect Pests:

It is susceptible to euonymus scale and is frequently damaged by deer. Powdery mildew can be a problem, as can mites, leaf miners, aphids, mealybugs and crown gall. Additional diseases which may appear include witches’ broom, stem dieback, and fungal leaf spots. Plants can be susceptible to attacks by caterpillars and are often damaged during the flowering season
