A common ornamental cherry in towns; single-flowered forms give spring nectar and pollen, but the widespread double-flowered cultivars offer bees almost nothing.
Most trees planted as Japanese cherry are ornamental cultivars derived from Prunus serrulata, of East Asian origin, and closely related species. For the beekeeper the key distinction is flower structure: single forms with five petals have open nectaries and many anthers, like other cherries; in double cultivars most of the stamens have turned into petals and there is very little nectar.
It flowers for about two weeks in April and May; double cultivars usually bloom a little later than single ones. On cool, windy spring days bee flight remains limited.
It has no honey of its own; it contributes to the spring build-up of colonies around towns.
Where a bee-friendly choice is wanted for street and park planting, single-flowered forms, wild cherry or mahaleb cherry should be preferred. The common pink double cultivar may look spectacular, but it is poor forage for bees.
