Besides the fruit, cherries also have attractive flowers, and they are commonly planted for their flower display in spring; several of the Asian cherries are particularly noted for their flower displays. The Japanese sakura in particular are a national symbol celebrated in the yearly Hanami festival. Many flowering cherry cultivars (known as ‘ornamental cherries’) have the stamens and pistils replaced by additional petals (”double” flowers), so are sterile and do not bear fruit. They are grown purely for their flowers and decorative value. The most common of these sterile cherries is the cultivar ‘Kanzan’.
