Kanzan CherryPrunus serrulata ‘Kanzan’

  • Kanzan Cherry - Prunus
The Kanzan (Kwanzan) cherry has double pink flowers and a vase-shaped form with a rounded crown that spreads with age, making the tree wider than it is tall at maturity. The new leaves are bronze colored, turning to dark green then yellow, orange or copper in fall. This is a fruitless cultivar. Kwanzan cherry is grafted onto Prunus avium (mazzard) stock or grown from cuttings. Trees propagated on their own roots are preferable. Easily transplanted, it prefers a site with full sun, loose, well drained soil with plenty of moisture. It is somewhat tolerant of alkaline soil and drought but is sensitive to pollution and stresses in general. For these reasons and because of its susceptibility to pests and disease, the life span is limited from 15 to 25 years. The great beauty of this tree makes it well worth planting for this short period of time.

Wildlife Value

Named after a mountain in Japan, the Kanzan (Kwanzan) cherry tree is native to China, Japan and Korea. The original name is 'Sekiyama,' but it is rarely used. Introduced to America in 1903, it was made famous by the glorious floral displays at the annual Cherry Blossom Festival in Washington, D.C.
