The ‘Sunshine Chinese Privet’, often marketed as ‘Sunshine Ligustrum’, is a distinctive evergreen shrub prized for its vibrant, year-round chartreuse to golden-yellow foliage. This cultivar, Ligustrum sinense ‘Sunshine’, is a sterile, non-invasive selection that does not produce flowers or berries. Its compact habit and bright color offer a striking contrast in the landscape, providing consistent brightness even through the winter months.
Choosing the Location and Planting
Selecting the proper site ensures the shrub develops its signature golden color. ‘Sunshine Ligustrum’ thrives best in USDA hardiness zones 6 through 10, tolerating temperatures down to approximately -10°F. While it tolerates partial shade, a minimum of six to eight hours of direct, full sun is required to maintain the most intense yellow hue. Insufficient sunlight will cause the foliage to revert to a duller, lime-green color.
The shrub is adaptable to various soil types, flourishing in sandy, loamy, or clay soils. Excellent drainage is the most important consideration, as waterlogged conditions can lead to root rot. The plant prefers a soil pH that is slightly acidic to neutral (6.0 to 7.5), though it tolerates mildly alkaline conditions. When planting, dig a hole twice as wide as the root ball but no deeper, ensuring the top of the root mass remains level with the surrounding grade.
For creating a dense hedge, plants should be spaced closely, often two to four feet apart, allowing branches to intermingle as they mature. After positioning the shrub, backfill the hole and tamp the soil gently to remove air pockets. Follow this with a thorough, deep watering to settle the soil around the roots and establish the root system.
Essential Daily Maintenance
After initial planting, a consistent watering schedule is necessary to help the root system become established. Newly planted shrubs should be watered deeply once or twice a week, allowing the top inch of soil to dry out slightly between applications. Deep watering encourages downward root growth, making the plant more resilient over time. Once mature (typically after one full growing season), ‘Sunshine Ligustrum’ exhibits excellent drought tolerance and only requires supplemental watering during extended dry periods.
Fertilization should occur in early spring before new growth begins, and optionally again in late summer or early fall. Applying a balanced, slow-release granular fertilizer, such as a 10-10-10, provides a steady supply of nutrients. Slow-release formulations prevent a sudden surge of nitrogen, which can lead to weak growth and dull the vibrant foliage color. Avoid excessive fertilization, as too much nitrogen diminishes the bright yellow hue.
Pruning and Shaping Techniques
‘Sunshine Ligustrum’ responds well to pruning, which is necessary to maintain its desired size and shape, especially for formal hedges. The most beneficial time for major pruning is in late winter or early spring, just before the plant breaks dormancy. This timing encourages a flush of dense new growth, allowing the shrub to quickly recover and display bright new foliage throughout the season.
For maintaining a manicured, formal appearance, the shrub can be lightly sheared throughout the spring and summer growing season. Frequent light trimming encourages the plant to become more compact and dense, preventing interior branches from becoming leggy. When shearing, prune the top narrower than the bottom to ensure sunlight reaches the lower foliage and maintains density from the base up.
Selective thinning or hand pruning, where individual branches are cut back deeper, controls size and allows light penetration. This method is useful for rejuvenation pruning, where an overgrown shrub is cut back by up to one-third of its size to stimulate robust new growth. Since the shrub grows moderately fast (typically adding 12 to 24 inches per year), multiple annual prunings may be needed to control its dimensions.
