Discussion

Broussonetia papyrifera is now widely naturalized in eastern United States. Frequently planted as a shade tree around dwellings, it is often considered undesirable because of its aggressiveness, shallow root system, and soft, brittle wood. The bark of the tree is used to produce a barkcloth.
