White Mulberries in Red Hook: a legacy of Competition with China, 18th Century

White mulberries were imported to feed silkworms!

American competition with China goes back centuries.
To compete with China’s silk industry, white mulberries were imported into the American colonies because silkworms only eat white mulberry leaves. It is possible, however that the Chinese in order to protect their silk trade and trade secrets provided dud cultivars of the Mulberry to the Jesuits who were trying to buy it on black market.

A major shipment into this region was in 1774 by William Prince who sold plants in Flushing. At that time, the East River was the main travel route between Flushing, Manhattan and Brooklyn in boats, canoes and pirogues (native canoes). 

The effort to breed silkworms failed, but Red Hook and NYC now have many mulberry trees.   The native mulberry is red. The white is invasive and hybridizes with it.
