Magness et al. 1971 Mulberry trees are rather small, up to 20 feet, with rather large leaves, and bear fruits resembling blackberries in size and shape.
Fruit is edible, but low in acid and rather insipid.
It is too soft for shipment to market, so rarely enters into commerce. Trees are often planted as ornamentals, and fruit may be used locally. M. alba L., the white or Chinese mulberry, produces fruit 1 to 2 inches long. Its leaves are used to feed silkworms. M. nigra L. is the black mulberry of Europe, cultivated locally there for its fruit.
