More Details

The Korean Spice Viburnum, scientifically known as Viburnum carlesii, is a highly fragrant, deciduous shrub renowned for its spherical clusters of pink-budding flowers that open to white blooms in early to mid-spring. This medium-sized shrub captivates with its spicy-sweet perfume, filling the garden air and attracting pollinators. The dark green leaves turn a beautiful burgundy color in the fall, adding seasonal interest. Korean Spice Viburnum is valued not only for its aromatic flowers and attractive foliage but also for its versatility in the landscape, serving beautifully as a specimen plant, in mixed borders, or as part of a foundation planting. Its compact growth habit and ease of care make it a favorite among gardeners seeking to add sensory appeal to their outdoor spaces.

Growth rate: Moderate growth rate; mature height of 4-6 feet and width of 4-6 feet.

Please note: Images on our website depict plants and trees at full maturity to showcase their expected grown characteristics. These images are illustrative examples only and do not represent the size of plants or trees upon delivery.

Pruning: Prune immediately after flowering to shape or maintain size and to remove any dead or damaged wood.

Fertilization: Apply a balanced, slow-release fertilizer in early spring to encourage healthy growth and flowering.

Winter Protection: Applying a layer of mulch around the base of the shrub helps insulate the roots and protect them from freezing temperatures.

Select a location with well-draining soil in full sun to partial shade. Dig a hole as deep and twice as wide as the root ball. Plant the viburnum, backfill with soil, and water thoroughly. Space plants according to their mature width to allow for proper growth and air circulation.

Water regularly during the first growing season to establish a deep, extensive root system; once established, it is relatively drought-tolerant, requiring only occasional watering during dry periods. Performs best in full sun to partial shade, with sufficient sunlight ensuring the most prolific blooming and fragrance.

Zones 4-7

Korean Spice Viburnum thrives in USDA Zones 4-7, adapting well to a range of soil types, provided they are well-drained. It prefers full sun to partial shade, with the latter particularly beneficial in hotter climates to prevent leaf scorch.

Frequently Asked Questions

Korean Spice Viburnum typically reaches a mature size of about 4 to 6 feet in height and width. However, in optimal conditions, it can sometimes grow slightly larger, reaching up to 8 feet in height and width. The size of the plant depends on various factors including environmental conditions, soil quality, and pruning regimen.

Korean Spice Viburnum is considered a moderately fast-growing shrub. Under optimal conditions, it can grow at a rate of around 12 to 24 inches per year. However, growth rate can vary depending on factors such as soil quality, sunlight exposure, water availability, and climate conditions. Generally, it establishes well and fills out over a few years, reaching its mature size of 4 to 6 feet in height and width within 5 to 10 years. Regular watering, proper pruning, and fertilization can help promote healthy growth and faster establishment.

The best place to plant Viburnum is in a location that receives partial to full sunlight, with well-drained soil. It thrives in moist, fertile soil but can tolerate a range of soil types, including clay and sandy soils. Additionally, choose a site with enough space for the Viburnum to grow to its full size, as it can reach heights and widths of up to 6 to 8 feet. Planting in an area protected from strong winds can also help prevent damage to the foliage and flowers.

Korean Spice Viburnum is prized for its fragrant flowers, which emit a sweet, spicy scent. The fragrance is often described as reminiscent of cloves or spice, with hints of vanilla. This delightful aroma makes it a popular choice for gardens and landscapes, adding sensory appeal to outdoor spaces.

Korean Spice Viburnum is not considered invasive in most regions. It is generally well-behaved and not known to aggressively spread or outcompete native vegetation. However, it's always a good idea to check with local authorities or extension services to ensure that a particular plant species is not considered invasive in your specific area, as invasiveness can vary depending on local conditions and ecosystems.

Korean Spice Viburnum berries are not typically considered edible for humans. While some birds may consume them, they are not recommended for human consumption as they can cause mild gastrointestinal upset if ingested in large quantities. It's best to avoid eating the berries and instead appreciate the plant for its ornamental qualities, including its fragrant flowers and attractive foliage.

The Korean Spice Viburnum typically blooms in spring, typically in April to May, and the flowering period can last for several weeks, typically around two to four weeks. However, the exact duration of blooming can vary depending on factors such as climate, growing conditions, and specific cultivar. After the blooming period, the Viburnum may produce attractive foliage and, later in the season, may develop colorful berries, adding further interest to the landscape.

Winterizing your Viburnum, particularly the Korean Spice Viburnum, involves several steps to help protect it from harsh winter conditions:

Mulching: Apply a layer of organic mulch, such as wood chips or shredded bark, around the base of the plant. Mulch helps to insulate the soil, regulate temperature fluctuations, and retain moisture, which is especially important during winter.

Watering: Continue to water the Viburnum adequately until the ground freezes. Well-hydrated plants are better equipped to withstand winter stress. Avoid overwatering.

Pruning: Minimal pruning is typically needed for Viburnums, but any dead, damaged, or diseased branches should be removed before winter to prevent the spread of disease and minimize potential damage from snow or ice accumulation.

Protection from Wind and Snow: Consider installing windbreaks or burlap screens around the plant to protect it from drying winter winds. Additionally, gently brush off heavy snow accumulation from branches to prevent breakage.

Anti-desiccant Spray: Applying an anti-desiccant spray to the foliage can help reduce moisture loss through transpiration during winter. Follow the product instructions carefully for application.

Avoid Fertilizing: Cease fertilization in late summer or early fall to avoid stimulating new growth, which can be more susceptible to winter damage.

Consideration of Location: When planting Viburnums, choose a location that offers some protection from harsh winter conditions, such as exposure to prevailing winds.

Monitor for Pests and Disease: Winter is a good time to inspect your Viburnum for signs of pests or disease. Address any issues promptly to prevent them from worsening during the dormant season.

By taking these steps, you can help ensure that your Viburnum, including the Korean Spice variety, remains healthy and resilient throughout the winter months.

Several factors could contribute to a Korean Spice Viburnum not blooming:

Young Age: It's common for young shrubs to take a few years to establish themselves before producing abundant flowers. If your plant is still relatively young, it may simply need more time to mature.

Pruning: Viburnums generally bloom on old wood, so if the plant is pruned at the wrong time or too aggressively, it may remove potential flower buds. Avoid heavy pruning or prune immediately after flowering to ensure you're not cutting off next year's blooms.

Improper Pruning: Pruning at the wrong time or not pruning at all can both impact flowering. Always prune at the appropriate time, which is typically after flowering in spring or early summer.

Lack of Sunlight: Viburnums typically prefer full sun to part shade. If the plant is not receiving enough sunlight, it may not bloom as abundantly.

Nutrient Deficiency: Ensure that the plant is receiving adequate nutrients, particularly phosphorus, which promotes flowering. Using a balanced fertilizer or one specifically formulated for flowering shrubs may help.

Environmental Stress: Stress factors such as drought, extreme temperatures, or poor soil conditions can hinder blooming. Ensure the plant is adequately watered, especially during dry periods, and that it's planted in well-draining soil.

Pests or Disease: While less common, certain pests or diseases can affect the health of the plant, potentially impacting its ability to bloom. Regular inspection for signs of pests or disease and appropriate treatment if necessary can help maintain plant health.

Korean Spice Viburnum is a deciduous shrub known for its stunning visual appeal throughout the year. In spring, it bursts into fragrant clusters of pink to reddish buds that gradually open to reveal beautiful white flowers. These flowers are not only visually appealing but also emit a delightful fragrance that fills the air.

As spring transitions into summer, Korean Spice Viburnum continues to impress with its glossy green foliage, providing a lush backdrop in the garden. In autumn, the leaves turn vibrant shades of red to purple, adding a splash of color to the landscape.

Even in winter, when many other plants are dormant, Korean Spice Viburnum remains attractive. Its bare branches offer an architectural element to the garden, especially when dusted with snow.

Overall, Korean Spice Viburnum is a multi-seasonal beauty, offering something delightful to behold in every season of the year.
