What is the common name for Cornus mas?

The common name for Cornus mas is indeed the Cornelian Cherry. This name is derived from the fact that the tree produces cherry-like, edible red fruits in the late summer, although it is not a true cherry in the botanical sense. Cornus mas is a deciduous shrub or small tree native to Europe and parts of Asia, valued for its early spring flowers, which are often one of the first to bloom, attracting pollinators. The fruits are also used in jellies and jams, emphasizing its utilitarian value in addition to ornamental aesthetics.

The other options refer to entirely different species: Red Horsechestnut is known for its showy flower clusters and is a different genus, while the Katsura Tree is recognized for its heart-shaped leaves and fragrant autumn foliage. Himalayan Birch is a type of birch tree notable for its striking white bark and is unrelated to the Cornelian Cherry. Thus, the distinction between these trees highlights the unique characteristics that define Cornus mas and contribute to its common name.
