A Kwanzan in Winter

Kwanzan Flowering Cherry, Prunus serrulata 'Kwanzan'

 

One of my all time favorite trees, the Kwanzan Cherry was named after a mountain in Japan and is native to China, Japan, and Korea. The upright, spreading form can reach 15 to 25 feet tall and is quite beautiful with attractive, double, pink flowers. Kwanzan Cherry has new growth that is bronze colored, turning yellow, orange, or copper in the fall, does not bear fruit, prefers full sun, is intolerant of poor drainage, and is easily transplanted. An annual festival at the Tidal Basin in Washington, D.C. commemorates the annual bloom of this species along with Yoshino Cherry, Prunus × yedoensis.

Known for its thin branches that are not inherently strong, bark can easily split and crack. Branches fall frequently in winter due to high winds and cold weather. Therefore, proper pruning must take place during tree development. The tree branches must be evenly spaced to produce a stronger framework for support in less desirable conditions.
