The term “pink willow tree” sparks curiosity, referring to a specific, visually striking plant that displays beautiful pink coloration, though it is not a formal botanical name.
Understanding the “Pink Willow”
The plant most often associated with the “pink willow tree” moniker is Salix integra ‘Hakuro-nishiki’. This plant is widely known by several common names, including Dappled Willow, Variegated Willow, Flamingo Willow, Japanese Dappled Willow, Nishiki Willow, or Shrimp Willow. It is a deciduous shrub native to wetlands and riverbanks in Japan, Korea, and parts of eastern Russia.
While botanically classified as a shrub, the Dappled Willow can be trained or grown to resemble a small tree, which contributes to the common “pink willow tree” perception. The “pink” aspect comes primarily from its unique new foliage, which emerges with vibrant pink tones in the spring.
Distinctive Appearance and Seasonal Changes
The Dappled Willow features variegated foliage, displaying multiple colors. In spring, new growth emerges with bright shell-pink tips, creating a striking effect. As the season progresses into summer, these pink hues gradually mature into a mottled pattern of creamy white and green. Its narrow, lance-shaped leaves are attractive during this transition.
Beyond its leaves, the plant offers multi-season interest. Young stems often have a pinkish tint, turning vibrant coral or brick red in autumn, especially new growth. This red stem coloration contrasts strikingly against winter landscapes. The Dappled Willow typically forms a rounded shrub with arching branches, reaching 4 to 10 feet in height and 5 to 10 feet in spread.
Growing Conditions and Maintenance
Dappled Willows thrive in locations that receive full sun to partial shade. While full sun generally encourages the most vibrant leaf coloration, the plant benefits from some afternoon shade in hotter climates to prevent scorching. They prefer consistently moist, well-drained, and fertile soils. Although adaptable to various soil types, including loamy, sandy, or clay soils, amending them with organic matter can enhance growth and color.
Regular watering is important, especially for young plants, which may need water twice weekly to establish a strong root system. Once established, watering frequency can be reduced, but the soil should remain consistently moist without becoming waterlogged. It is known for its fast growth rate, often growing 2 to 3 feet per year.
Pruning is beneficial, especially in late winter or early spring before new growth emerges. This encourages a flush of new, colorful foliage and helps maintain desired size and shape. An additional light prune during the growing season can stimulate more characteristic pink growth. Dappled Willows are hardy in USDA plant hardiness zones 4 through 9.
