Distributed in: Afghanistan, Burma, China, India, Iran, Japan, Pakistan (Oceania and S.E. Asia, Western Europe)

Distribution overview: Although White mulberry is native to China, it is widely cultivated in other areas including the United States, western Europe, northern India, Afghanistan, and Kashmir. It is a naturalized species in the eastern United States and in the Pacific states. It is also occasionally planted in southern England. In India, the species is found in the plains and the Himalayas, up to an elevation of 11000 feet (3355 m). The tree is drought resistant, and has become adapted to dry, warm areas.

Common uses: Agricultural implements, Bent Parts, Boat building (general), Bobbins, Cabinetmaking, Chairs, Chests, Concealed parts (Furniture), Desks, Dining-room furniture, Dowell pins, Dowells, Drawer sides, Fine furniture, Floor lamps, Fuelwood, Furniture , Furniture components, Furniture squares or stock, Furniture, Handles, Handles: general, Hatracks, Heavy construction, Hockey sticks, Kitchen cabinets, Light construction, Living-room suites, Office furniture, Poles, Posts, Pulp/Paper products, Radio - stereo - TV cabinets, Rustic furniture, Shafts/Handles, Sporting Goods, Stools, Tables , Textile equipment, Tool handles, Turnery, Utility furniture, Utility poles, Vehicle parts, Wardrobes, Wheel spokes

Product sources: Silk worms are fed on the leaves of White mulberry.

Environment profile: Data source is World Conservation Monitoring Center This species is officially classified as Rare within its natural habitat in Liechtenstein, Western Europe

Shrinkage, Tangential = fairly large
Shrinkage, Radial = small
Shearing strength (parallel to grain) = very high
Modulus of Elasticity (stiffness) = very low
Max. crushing strength = medium
Hardness (side grain) = hard
Bending strength (MOR) = low
Toughness-Hammer drop (Impact Strength) = high
Shearing strength (parallel to grain) = very low
Modulus of Elasticity (stiffness) = low
Max. crushing strength = low
Max. crushing strength = high
Hardness (side grain) = medium
Compression strength (parallel to grain) = high
Bending strength (MOR) = medium
The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple. Hardness is rated as medium. It resists denting and marring about as well as white oak or birch. The weight is high. The density is high.
