Euonymus japonicus 'Silver King', also known as Silver King Euonymus, is a striking evergreen shrub celebrated for its attractive variegated foliage. The glossy, leathery leaves are dark green with a wide silver-white margin, creating a dramatic contrast that shines year-round. This cultivar has a compact, upright growth habit, typically reaching 3 to 6 feet in height with a spread of 3 to 5 feet, making it a versatile choice for hedges, borders, or specimen planting. In spring, small, inconspicuous flowers appear, followed by red berries in the fall, though the plant's primary appeal lies in its stunning foliage. 'Silver King' is a hardy and low-maintenance plant, making it ideal for a variety of landscapes, from formal gardens to more casual settings.
Euonymus japonicus 'Silver King'
- Light: Prefers full sun to partial shade. For the brightest foliage color, full sun is best, although it can tolerate light shade. In too much shade, the variegation may become less pronounced.
- Watering: Water regularly, especially during dry spells, to help establish a strong root system. Once established, 'Silver King' is moderately drought-tolerant but benefits from deep watering in extended dry periods.
- Soil: Grows well in well-draining, moderately fertile soil. It is adaptable to various soil types, including loamy, sandy, and clay soils. Avoid waterlogged areas, as this can lead to root rot.
- Temperature: Hardy in USDA zones 6-9. This plant is suited to temperate climates and can tolerate cold winters but may require some protection from harsh frosts in colder areas.
- Humidity: Tolerates average humidity levels. Ensure good air circulation to prevent fungal diseases, particularly in damp or poorly ventilated areas.
- Fertilizer: Apply a balanced, slow-release fertilizer in early spring to promote healthy growth and vibrant foliage. Avoid over-fertilizing, as it may lead to overly vigorous growth and reduced variegation.
- Pruning: Prune after flowering or in early spring to maintain a tidy shape and remove any dead or damaged branches. Light pruning helps keep the plant compact, but heavy pruning should be avoided to preserve its natural form and foliage.
- Propagation: Propagate by softwood or semi-hardwood cuttings taken in late spring or early summer. Rooting hormone can help promote faster root development.
- Pests/Diseases: Generally pest-resistant but may occasionally attract aphids or scale insects. It is also susceptible to fungal diseases such as powdery mildew, particularly in humid conditions. Regularly check for pests and remove any affected leaves.
- Landscape Use: Ideal for hedges, borders, and as a specimen plant. Its compact size and attractive variegated foliage make it perfect for formal gardens, foundation plantings, or as an ornamental shrub in mixed landscapes. It can also be used to add structure and color to areas that receive a mix of sun and shade.
