Viburnum dentatum and Viburnum dilatatum are two species of shrubs that are often confused with each other due to their similar appearance. However, there are several key differences between the two that can help you distinguish them.
1. Leaf Shape: One of the easiest ways to tell the difference between Viburnum dentatum and Viburnum dilatatum is by looking at their leaves. Viburnum dentatum has rounder leaves with a deeply toothed margin. On the other hand, Viburnum dilatatum has leaves that are more elongated and less toothed.
2. Leaf Texture: Another distinguishing feature is the texture of the leaves. Viburnum dentatum leaves can be either very pubescent (covered in fine hairs) or glabrous (smooth and hairless). In contrast, Viburnum dilatatum leaves are typically glabrous.
3. Fruit Color: The fruits of these two species also differ in color. Viburnum dentatum produces dark purple or blue fruits that are round in shape. In contrast, Viburnum dilatatum bears bright red fruits that are also round.
4. Fruit Size: In addition to the color difference, there is also a variation in the size of the fruits. Viburnum dentatum fruits are generally smaller, while Viburnum dilatatum fruits are larger and more noticeable.
5. Growing Conditions: While both species are adaptable and can tolerate a range of growing conditions, there are slight differences in their preferences. Viburnum dentatum is more commonly found in moist to wet soils and is more tolerant of wetter conditions. Viburnum dilatatum, on the other hand, is more adaptable to drier soils and can tolerate a wider range of moisture levels.
6. Native Range: Viburnum dentatum, also known as Arrowwood Viburnum, is native to eastern and central North America. Viburnum dilatatum, commonly called Linden Viburnum or Japanese Snowball, is native to eastern Asia.
7. Landscape Use: Both Viburnum dentatum and Viburnum dilatatum are popular choices for landscaping due to their ornamental features. However, Viburnum dentatum is often preferred for its attractive fall foliage colors and its ability to attract birds with its fruit. Viburnum dilatatum is known for its showy fruit display and is often used as a focal point in the landscape.
While Viburnum dentatum and Viburnum dilatatum may share some similarities in appearance, there are distinct differences that can help you identify each species. Pay attention to leaf shape, texture, fruit color and size, as well as their native range and preferred growing conditions. By considering these factors, you can confidently differentiate between Viburnum dentatum and Viburnum dilatatum in your garden or landscape.
