Euonymus japonicus (evergreen spindle or Japanese spindle) is a species of flowering plant in the family Celastraceae, native to Japan, Korea and China.^{[1] [2]} It is an evergreen shrub or small tree growing to 2- tall, with opposite, oval leaves 3–7 cm long with finely serrated margins. The flowers are inconspicuous, greenish-white, 5 mm diameter. In autumn, orange fruit hangs below the flaring pink seed coverings.

Horticultural cultivars

Euonymus japonicus is a popular ornamental plant for parks and gardens, both in its native area and also in Europe and North America. In particular the numerous cultivars which have been selected (often with variegated or yellow leaves) are widely grown in all soil types in sun or shade. Some of the more distinctive cultivars are:

• 'Albomarginatus' – leaves green, narrowly margined white
• 'Aureo-marginatus' – also called "Golden Euonymus", variegated green and butter yellow leaves^[3]
• 'Bravo' – green and creamy-yellow variegated leaves, upright habit
• 'Chollipo'^[4]
• 'Green Spire' – evergreen columnar narrow shrub
• 'Kathy' – green and white variegated, broad leaves, shorter growing than most
• 'Latifolius Albomarginatus' – green leaves with broad white margin
• 'Ovatus Aureus'^[5]
• 'President Gauthier' – dark green and creamy-white variegated leaves, slightly more lax habit than others
• 'Susan'^[6] – dark green leaves, narrowly marginated creamy-white
