Choji-zakura

Clove cherry refers to the mahaleb cherry (Prunus mahaleb), a small to medium-sized tree in the family Rosaceae native to central and southern Europe, western Asia, and North Africa. The common name 'clove cherry' refers to the clove-like fragrance of the flowers, bark, and wood, produced by coumarin compounds that also give the wood a distinctive pleasant scent when cut. It grows on dry, rocky slopes, limestone outcrops, scrublands, and forest margins, tolerating thin, alkaline soils and drought conditions that other cherries cannot withstand. The small white flowers in dense racemes are profusely produced in spring, making this an attractive ornamental species. The small black cherries, though bitter and barely edible to humans, are consumed by birds that disperse the seeds. Prunus mahaleb timber is dense, fine-grained, and aromatic, traditionally prized for the manufacture of tobacco pipe bowls, small cabinet work, and turned objects. The wood's hardness and resistance to splitting also make it a traditional choice for musical instrument parts and tool handles. The species is widely cultivated as a rootstock for grafting cultivated sweet cherry varieties due to its disease resistance and dwarfing effect.
