Discover More Information On Ivory Silk Japanese Tree Lilac

Do you want a tree that stands out in your yard? If you love the look of lilacs, then you might want to choose the Ivory Silk Japanese tree lilac (Syringa reticulata ‘Ivory Silk’) for your outdoor space. This lilac variety grows taller and broader than other lilacs. You can enjoy all the fragrance and beauty of the lilac in a supersized package.

Plant Attributes

If you are looking to make a significant impact in your yard, you need to choose the Ivory Silk Japanese tree lilac. This small tree produces foot-long flower panicles in late June. After other lilacs have finished blooming for the season, these trees continue to flower. Your landscape will bloom with creamy white flowers that produce a sweet scent in the early summer. Once the blooms have finished, enjoy the beautiful shade from the Ivory Silk’s large leaves. During the summer, the dark green foliage is a spectacular sight. When this lilac drops its leaves, you will fall in love with the attractive brown bark. This bark also adds some texture and dimension to your winter landscape.

Landscape Use

The Ivory Silk Japanese tree lilac is a versatile choice. Since the lilac reaches a height of 20 feet, you might want to use this tree in a small yard. It also works well as an ornamental focal point for a lush garden border. Make sure to keep those lower branches trimmed and tidy to help maintain its beautiful tree form.

For those spaces that need some privacy, plant these lilacs in a long row near your fence. During the growing season, you will have a great privacy border as the lush foliage offers exceptional shade. You want the lower branches to grow out at the trunk’s bottom to provide some solitude for your spaces. Those lower branches will fill in as the lilac develops into a tall flowering shrub. You should plant these trees about 12 feet apart from the center. A group of Ivory Silk lilacs planted in a slight zig-zag pattern or a gentle curve give a more naturalized appearance to your yard. Since these trees can grow thick, keep them about 12 feet away from a fence or building.

If you want an excellent tree for a parkway or street, plant these beauties between the sidewalk and roadway. These lilacs can handle salt and pollution, and they make a perfect option for urban or commercial spaces. Large parks will also benefit from the addition of the Ivory Silk. With these trees, you can expect many admirers to come and appreciate the beauty and fragrance of the Ivory Silk Japanese tree lilac.

Planting & Care

Ivory Silk Japanese trees thrive in USDA hardiness zones 3 to 7. For the best results with the blooms, you will want to plant in full sun. This tree is not affected by soil pH, but you need to make sure it is grounded in well-draining soil. In areas with heavy clay soils, add compost and soil conditioners around the tree. You might want to create a mound of fast-draining soil or make a raised bed in those drainage problem areas. Mulching can help to suppress weeds and hold in the moisture of the ground.

As a yard tree, consider adding a garden bed around the tree’s base for those landscapes. This bed ensures that any lawn fertilizer stays away from the roots. During the first season, you want to water it to help establish in your landscape. After that growing season, the lilac will become tolerant of drier conditions. However, you might need to water deeply to help the buds develop into full flowering clusters. During those periods of extreme heat, this lilac requires additional waterings.
