Frequently Asked Questions

Do viburnum like sun or shade?

Viburnum generally prefer full sun to partial shade. However, their light requirements can vary depending on the species. Some can tolerate full shade but may produce fewer flowers and develop a less dense foliage. Overall, a well-lit spot with some afternoon shade often works well for most types.

Are viburnum low maintenance?

Yes, they are generally considered low-maintenance plants. They are fairly adaptable to a variety of soil types and environmental conditions. Regular pruning is usually not mandatory unless you are aiming for a specific shape. They are relatively disease- and pest-resistant compared to other plants, making them an easy-care option for many gardens.

What does viburnum look like in the winter?

Their winter appearance largely depends on the species. Deciduous varieties will lose their leaves, revealing a skeletal structure that can be quite ornamental. Many species have persistent berries that add winter interest. Evergreen species maintain their leaves, providing year-round foliage. Some varieties also feature textured or colored bark that can be visually striking in the winter landscape.

How fast do viburnum grow?

The growth rate varies by species, but many are considered medium to fast growers. In general, you can expect your shrub to grow 1 to 2 feet (30-60 cm) per year under optimal conditions.

What is the most fragrant viburnum?

One of the most fragrant viburnums is Viburnum carlesii, also known as Koreanspice Viburnum. This deciduous shrub produces clusters of pinkish-white flowers in the spring that are highly aromatic, filling the garden with a spicy, clove-like fragrance. Viburnum × burkwoodii is another fragrant option, known for its pink to white flowers that emit a strong, spicy aroma. Both of these species are often planted near windows or walkways where their pleasant scent can be easily enjoyed.
