History
Morus nigra, the black mulberry, likely originated in the Caucasus and northern Iran, where it has been cultivated for fruit since at least 2000 BCE. Greek and Roman authors including Theophrastus, Virgil, and Pliny the Elder described its deep-purple fruit and medicinal uses. The tree spread through the Roman Empire into western Europe and reached England by the Middle Ages.
In 1608 James I of England ordered tens of thousands of mulberries planted to boost domestic silk production, but he mistakenly favored the wrong species since silkworms prefer the white mulberry Morus alba. The black mulberry nevertheless became a treasured dooryard tree, celebrated in folk song and cuisine. Ancient specimens survive at Syon House and other English estates, still bearing fruit.
Native to Western Asia, particularly Iran and Anatolia. Cultivated for over 4,000 years for both fruit and silkworm food. Some specimens in Iran and the UK are over 600 years old. Increasingly available in American specialty fruit nurseries as awareness of fresh mulberries' exceptional flavor spreads beyond the Asian-American community.

What It Symbolizes

Its dark, sweetly intense fruit is acknowledged as the finest of any mulberry species. To plant one is to expect great-grandchildren — the tree settles in for centuries and shares its sweetness with each generation that arrives.
