Description This cherry tree is the most popular of the double-flowered selections with its pink to magenta colored blossoms which hand in clusters of 2-5 flowers each.

Kanzan Flowering Cherry is a deciduous flowering tree which has the shape of an inverted cone when it is young, but latter develops into a round and spreading fashion when it is older. Some trees have a flat top when they are very old. At maturity this sterile cherry may attain a height of 25’ and a width of 35’.

In the spring new leaves emerge in April with a bronze cast, become green during the summer, and finish the season with a yellow-bronze color in the fall. Leaves are pointed, and have serrated edges.

Early April is when the pink bloom first emerges. With a week the tree will seemingly be covered with a complete coating of large double, purplish-pink showy flowers (23-28 petals per flower). The bloom lasts for up to 2 weeks.

During the dormant season the tree still has interest what with its grey bark having horizontal lenticils that give it a split-bark appearance.

Highly adapted to most soils and sites as long as they are well drained. This Prunus sp. variant is considered drought tolerant when mature.

On the west side of Cascade Mountains all flowering cherries are susceptible to brown rot blossom blight (Monilinia fructicola), as well as bacterial canker (Pseudomonas syringae pv. syringae). If a sunny site is selected, with good circulation, neither of these problems should be of major concern.
