What is the common name of Viburnum plicatum tomentosum 'Mariesii'?

The common name of Viburnum plicatum tomentosum 'Mariesii' is indeed Double-file Viburnum. This particular cultivar is well-known for its distinctive horizontal branching pattern, which creates a tiered or "double-file" appearance as it grows. The shrub typically produces white flat-topped flower clusters in the spring, followed by attractive fruit in the fall, which can serve as a visual highlight in a landscape.

The name reflects the unique arrangement of the flowers and leaves along the branches, which resemble two rows or files on each side of the plant. This feature not only adds to the aesthetic appeal but also makes it a popular choice among gardeners and landscape designers looking for structure and interest in their plantings.

In contrast, highbush blueberry refers to a completely different species related to fruit production, while creeping bugle is a ground cover with low, sprawling growth, and snowberry is another type of shrub that is distinct from the viburnum family. Each of these has its own ornamental or functional characteristics, further emphasizing the uniqueness of the Double-file Viburnum.
