Viburnum plicatum f. tomentosum Wabi-Sabi®: An In-depth Look

Native: While the species Viburnum plicatum is originally from China and Japan, Wabi-Sabi® is a cultivated variety developed specifically for certain aesthetic and functional garden traits.

Plant Type and Habit: This deciduous shrub has a unique, almost whimsical growth habit. Unlike other doublefile viburnums, which have a more structured, tiered habit, Wabi-Sabi® has a more rounded, somewhat irregular form.

Size: Wabi-Sabi® is a dwarf cultivar, typically growing to just 2-3 feet (60-90 cm) in height and 3-4 feet (90-120 cm) in spread. This makes it particularly well-suited to small gardens and spaces.

Flowers: This cultivar produces small but numerous white lacecap flowers that contribute to its ethereal look. The flowers are dense enough to give the impression of a snowy blanket when they’re in full bloom. Expect the blooms to appear from late spring to early summer, offering a lovely visual spectacle for several weeks.

Foliage: Its leaves are deep green with slightly serrated edges. In autumn, they can turn to shades of red and purple, making it a multi-seasonal attraction.

Hardiness: Generally hardy in USDA zones 5-8, it is a versatile plant that can tolerate a range of climatic conditions.

Uses: Given its dwarf size, Wabi-Sabi® is perfect for container gardens, small patios, and even as a front-of-border plant in garden beds. It also works well in mass plantings.

Wildlife: The shrub’s flowers attract various pollinators, including bees and butterflies.

Deer and Rabbits: The shrub has moderate deer resistance, which means it may escape browsing in areas with low deer pressure. Rabbits generally avoid it.

Invasiveness: Wabi-Sabi® is not known to be invasive within its recommended USDA hardiness zones, making it a good choice for responsible gardening.

Benefits: Its compact size makes it a versatile option for various garden applications. Its multi-seasonal interest, from blossoms to autumn foliage, adds value to any planting scheme.

How to Grow and Care for Doublefile Viburnum

Light: Prefers full sun to partial shade. Ensure it receives at least 6 hours of sunlight for optimal flowering and foliage color.

Soil: Adaptable to a wide range of soil types but prefers fertile, humus-rich, well-drained, loamy to sandy soil. Slightly acidic to neutral pH is ideal.

Water: Moderate water requirements. Water deeply once a week, especially during dry spells. Overwatering or poor drainage can lead to root rot.

Fertilizer: Apply a balanced, slow-release fertilizer in early spring. Over-fertilizing can lead to excessive growth but fewer flowers.

Pruning: Best pruned immediately after flowering to maintain shape and remove any dead or damaged branches. Avoid heavy pruning, as it may reduce next year’s blooms.

Propagation: Propagate through softwood cuttings in early summer.

Pests and Diseases: No serious insect or disease issues. Keep an eye out for aphids, scale insects, thrips, or viburnum beetle. Occasional disease problems include leaf spot, root rot, and botrytis. Apply appropriate treatments as needed.

By following these care guidelines, you can ensure that your Viburnum plicatum f. tomentosum thrives, offering seasonal interest and aesthetic appeal to your garden.
