However, detailed DNA studies revealed that they were complex interspecific hybrids with the Oshima cherry, so they are classified as the Prunus Sato-zakura group or Cerasus Sato-zakura group. [4] [12] [5] 'Kanzan' is the most popular Japanese cherry tree cultivar for cherry blossom viewing in Europe and North America.
