Euonymus japonicus var. japonicus

[Overview]
An evergreen shrub 1–6 m tall, found in forests near the coast.
The bark has shallow vertical grooves.
The leaves are simple, usually opposite, sometimes whorled or alternate, elliptic, 5–11 cm long and 2.5–6 cm wide, thick and glossy, with low serrations on the margin.
The petiole is 0.5–1.5 cm long.
Cymes 3–7 cm long arise from the leaf axils, each bearing 7–15 flowers.
The inflorescence has a stalk 2–5 cm long.
The flowers are 4-petaled, 7–8 mm across, and pale green.
The fruit is a globose capsule about 0.8–1.2 cm across, which ripens deep red and splits into 4, revealing glossy vermilion seeds.

[Uses]
The bark is used medicinally.

[Cultivation]
Propagate from seed or cuttings.
It grows well in any soil as long as the site is sunny.
It tolerates partial shade.
For potted plants, and for plants in the ground less than 2 years after planting, water thoroughly when the soil surface dries.
For established plants in the ground, rainfall is sufficient unless sunny weather continues in midsummer and the soil becomes severely dry.
Apply organic fertilizer around the plant as fertilizer in winter.
Powdery mildew and scale insects can occur.
