Noteworthy Characteristics

‘Shirotae’ (synonymous with ‘Mount Fuji’) is a flat-topped, deciduous flowering cherry that typically grows to 15-20’ tall. It is a medium-sized tree with horizontally spreading branching that often dips close to the ground. Mildly fragrant semi-double white flowers (to 2” wide) with 5-11 petals bloom in profuse clusters in spring (March-April) when new growth is emerging. Ovate to elliptic leaves (to 5” long) with aristate teeth emerge pale green tinged with bronze in spring, turn dark green by summer and finally display attractive shades of orange and red in fall. No fruits are produced by this cultivar. ‘Shirotae’ translates as snow white in reference to flower color.

Problems

Susceptible to a large number of insect and disease pests. Potential diseases include leaf spot, die back, leaf curl, powdery mildew, root rot and fireblight. Potential insects include aphids, scale, borers, leafhoppers, caterpillars, tent caterpillars and Japanese beetles. Spider mites may also be troublesome.

Garden Uses

Small flowering tree for the landscape. Good lawn specimen. May be planted in small groups.
