What Is a Tri-Color Dappled Willow?

The tri-color dappled willow, scientifically known as Salix integra ‘Hakuro-nishiki,’ is a deciduous shrub native to Japan, Korea, and eastern Russia. You can plant these bushes as individual trees or together as a privacy screen, but they can be a little demanding. They are popular with gardeners because of its colorful foliage and rapid growth rate. Homeowners like their versatility because they can grow the tri-color dappled as a shrub or train it into a small tree. 

Historical and Cultural Significance

Across its native regions, the tri-color dappled willow holds cultural significance. In Japan, they are used in traditional gardens to symbolize grace and subtle beauty. The plant’s rapid growth also makes it a symbol of resilience, a trait celebrated in the wake of adversity. Korean gardens use the willows as wind barriers. In Russia, they add willows as garden ornaments, plant them for barriers against the wind, and more.

Appearance and Characteristics

Dappled willow trees have branches that arch delicately, set off with oblong, narrow variegated leaves. Their colors change with the seasons. The leaves are pink-tinged in the spring and give way to whitish-green growth in summer, creating an elegant dappled appearance. Colors are brightest when the trees are planted in direct sunlight. Pruning encourages new growth with more vivid color.

In the fall, the leaves turn yellow and drop, revealing coral-red stems by winter.

Growth Rate and Mature Size

Dappled willows grow at a fast rate of 2–3 feet per year, achieving their maximum height of 8–10 feet in just a few seasons. Their maximum width is also 8–10 feet, giving them a rounded shape that works extremely well as a privacy hedge when planted in a row.

Most landscape designs look sparse in those first few years after planting.

Bark Texture and Twigs

Tri-color dappled willows have smooth, reddish-brown bark. Their bark grows more textured as they age, and their twigs are slender and flexible. These eye-catching trees provide visual interest even in winter when the tree loses its leaves, revealing the bark and twigs.

Environmental Impact and Wildlife

The tri-color dappled benefits the local ecosystem. They’re host plants for certain butterfly larvae, and many birds find shelter under them. They also help to prevent soil erosion with their root systems.

Ideal Growing Conditions

Tri-color dappled willow trees don’t require much maintenance. They are adaptable and can tolerate growing in a wide range of soils.

• Hardiness Zones: USDA Hardiness Zones indicate the regions where different plants are suited for their ideal growth. Tri-color dappled willow trees do best in Zones 4–9, excellent for gardens in the Midwest and North.
• Soil preferences: Dappled willow trees thrive in moist, well-drained, slightly acidic to alkaline soil, but they can tolerate poor soil. The willows prefer to avoid sandy and clay soils and will produce less robust growth and paler colors.
• Sunlight recommendations: Dappled willow trees prefer full sunlight, or at least six hours of direct, unfiltered sunlight per day. However, they can also grow in partial shade.
• Watering: Dappled willow trees require a lot of moisture. When they’re young, you’ll need to water them deeply twice a week. You should feel moisture in the soil at least 2 inches down. As the tree ages, you can water it less frequently, giving it 1 inch of water once every week.

Planting Your Tri-Color Dappled Willow

Now that we’ve covered their requirements, we’ll explain how to plant your tri-color dappled willow, when, and what they grow well with.

Best Time To Plant

We recommend you plant a tri-color dappled willow in mid-to-late fall or early spring. Although the air is cool, the soil will be warm enough for root growth.

Step-By-Step Planting Guide

Follow these steps to plant your tri-color dappled willow:

1. Choose a location with full sun to partial shade and well-draining soil.
2. Dig a hole twice the width of the root ball and 1 inch shallower than its height.
3. Place the tree in the hole and check that it’s level and at the proper depth.
4. Backfill the hole with soil, tamp on it to eliminate air pockets.
5. Water deeply to settle the soil around the roots.
6. Apply a 3-inch layer of mulch around the base of the tree and extend to a 2–3 foot radius.

Companion Planting Suggestions

If your landscaping project includes other plants, consider adding companion plants, such as hostas, ferns, and astilbes. These plants prefer similar conditions, so not only will they complement the tree, they’ll help to retain soil moisture too.

Care and Maintenance

Proper care and maintenance will help your tri-color dappled willow thrive and maintain its beautiful appearance year after year.

Fertilizing Tips

The best time to apply fertilizer is early in spring before there is any new growth. Fertilization will help boost growth and the vibrancy of the foliage. Find a balanced, slow-release fertilizer. This will help the tree stay healthy and grow vibrant foliage. Follow the manufacturer’s guidelines carefully because if you over-fertilize, it can weaken the plant.

Pruning Techniques

Pruning tri-color dappled willow trees is not necessary, but dappled willows do respond well to it. Pruning can make the colors bolder because it encourages new growth. You can cut up to one-third of its branches at a time without having a negative impact on the root system. Be sure to prune your tree in late winter.

Winter Care

Tri-color dappled willows are hardy in USDA Zones 4–9. You don’t need to worry about providing special winter protections. If you live in colder zones, consider applying an extra mulch to protect your tree against extreme temperatures.

Seasonal Care Schedule

You can apply fertilizer in the spring. During the summer, focus on maintaining soil moisture levels. When the weather gets cooler in the fall, put down mulch and you can prune in late winter. All of these steps will result in a healthy tree showcasing vibrant colors.

Landscape Uses

You can use tri-color dappled willows in a few different ways, which include: 

• Erosion control: Willows help to control soil erosion because of their extensive root system.  You can plant them along riverbanks, near ponds, or in other erosion-prone areas. 
• Focal point: A single tri-color dappled willow can serve as a stunning focal point in your garden. Its changing colors and graceful form draw the eye and add year-round interest to your landscape design.
• Privacy screen: When planted in a row, tri-color dappled willows create an effective and attractive privacy screen. Their fast growth rate means you can establish a full hedge in just a few seasons, providing both beauty and seclusion to your outdoor space.

Potential Problems and Solutions

Despite how low-maintenance tri-color dappled willows are, you could run into the following issues, which include:  

• Adverse weather: Strong winds can break branches and if there’s a late spring frost, it can damage new growth. You can try to avoid this by planting your tree in a sheltered location and using frost covers during cold snaps.
• Pests and disease: Tri-color dappled willows resist most pests and diseases, but willow leaf beetles and fungal diseases can affect them. Follow the watering practices listed earlier and regularly inspect for beetles to prevent these issues.
• Root system concerns: Because they have extensive root systems, these willows could damage sewer lines, septic tanks, or patios if you plant them too close. Make sure you find a planting location that isn’t near underground utilities or foundations.

Our Conclusion

Tri-color dappled willow trees are fast-growing shrubs. When planted in direct sunlight, their leaves turn from pink-tinged in spring to a white-green color in summer. Since dappled willow bushes require a lot of water in their first few years, we recommend you water them deeply two times per week. They have a large root system, so plant them in an area far from patios and septic tanks. You can plant them as individual trees, accenting your garden, or as hedges if you need some privacy in your yard.
