The Golden Sunshine Willow is a deciduous shrub or small tree, cherished for its bright golden-yellow foliage. This plant provides vivid color and unique texture to any garden throughout the growing season.
Understanding Golden Sunshine Willow
The Golden Sunshine Willow, scientifically known as Salix sachalinensis ‘Golden Sunshine’, is a multi-stemmed deciduous shrub. It typically grows 8 to 18 feet tall with a spread of 5 to 7 feet. Its foliage emerges rich gold in early spring, maintaining a bright chrome color through summer before turning chartreuse in autumn. This willow is hardy in USDA Zones 4 through 10.
Planting and Site Selection
The Golden Sunshine Willow thrives in full sun to partial shade; full sun intensifies its golden foliage. It adapts to various soil types but prefers moist, well-drained conditions. While tolerant of wet, boggy soils, it also exhibits some drought tolerance once established. When planting, dig a hole one and a half times wider than the container, ensuring the top of the root ball remains level with the ground. Backfill with soil and water thoroughly, then apply mulch around the base to retain moisture.
Care and Maintenance
Consistent moisture is important for the Golden Sunshine Willow, especially during hot and dry periods. New plantings require frequent watering to establish robust root systems. Applying a balanced, slow-release fertilizer with higher nitrogen levels once or twice a year can promote vigorous foliage growth. The best time to fertilize is in early spring before new growth appears. Mulching around the plant’s base helps conserve soil moisture and suppress weeds.
Pruning for Health and Form
Pruning the Golden Sunshine Willow maintains its form, encourages new growth, and enhances foliage and stem vibrancy. The best time for significant pruning is in late winter or early spring, before new growth emerges, as pruning during active growth can cause sap to bleed. Techniques like coppicing or pollarding encourage a flush of new, brightly colored stems and dense foliage. Removing approximately one-third of the plant each year stimulates fresh growth and manages its size.
Landscaping Applications
The Golden Sunshine Willow makes a statement with its golden foliage and attractive winter stems. It is an excellent choice for mixed borders, providing strong contrast against green or dark-leaved plants. Given its preference for moist conditions, it performs well near water features or in areas prone to seasonal flooding. Its dense, upright, and spreading habit makes it suitable for hedges or screens, offering visual appeal and privacy.
Common Issues and Considerations
Golden Sunshine Willow can be susceptible to certain pests and diseases. Common issues include aphids, rust diseases, and canker, though the ‘Golden Sunshine’ cultivar shows resistance to leaf scorch, leaf spot, powdery mildew, and root rot. Its vigorous growth habit means regular pruning is necessary to control its size and maintain its form. Willow roots can be invasive, so avoid planting them near structures or pipes.
