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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
