Regarded one of the most ornamental of the flowering cherries, Prunus 'Kanzan' is a striking deciduous tree with several seasons of interest. In spring, it produces an amazing profusion of rich pink double flowers, 2.5 in. wide (6 cm), held in pendent clusters. They appear before the leaves unfold. Each blossom is packed with 20-30 petals. Since 'Kanzan' is sterile, they will not be followed by fruit. Reddish-copper as they emerge, the serrate, ovate leaves mature to dark green in summer, forming a dense canopy casting shade below. In fall, they warm up to various shades of orange and bronze before dropping. A graceful ornamental tree with an upright, vase-shaped habit, which can be planted in containers, along walks and streets and also be used as a bonsai specimen.
