Euonymus japonicus

Features and care

Euonymus japonicus, commonly known as Japanese euonymus, is an evergreen shrub widely used in hedges, borders, containers, and urban landscaping due to its dense foliage and adaptability. It features opposite, leathery, glossy, deep green leaves with finely toothed margins; numerous varieties also exist with variegated leaves in green, white, or yellow. It develops a compact, branching habit, typically reaching 2 to 4 meters in height, although it tolerates frequent pruning to maintain low, geometric, or screen-like shapes.

In spring and early summer, it produces small, inconspicuous, greenish-white flowers clustered among the foliage. In mature specimens, these flowers may develop into decorative capsules in shades of pink or orange, although its main ornamental value lies in the persistence and density of its leaves. Its good response to pruning, tolerance to urban pollution, and resistance to moderate salinity make it a very suitable species for coastal gardens, patios, dividing walls, and shrub borders.

It adapts to various soil types, including clay, provided they are well-drained. Once established, it tolerates drought but requires supplemental watering during the first year and during prolonged periods of heat. Waterlogging should be avoided, and good ventilation should be maintained in dense hedges to prevent powdery mildew and scale insects. Furthermore, its fruits and plant parts can be toxic if ingested. At Ornacom, we cultivate each specimen directly, guaranteeing a balanced shape and abundant flowering from the first years after planting.
