Morus alba L.
Mulberry family (Moraceae)
White mulberry was introduced to the U.S. during colonial times for the purpose of establishing a silkworm industry.
Distribution and Habitat
White mulberry is widespread in the U.S., occurring in every state of the lower 48 except for Nevada. It invades old fields, urban lots, roadsides, forest edges, and other disturbed areas.
White mulberry invades forest edges and disturbed forests and open areas, displacing native species. It is slowly outcompeting and replacing native red mulberry (Morus rubra) through hybridization and possibly through transmission of a harmful root disease.

Prevention and Control
White mulberry seedlings can be pulled by hand. Otherwise, cut the tree and grind the stump or paint the cut surface with a systemic herbicide like glyphosate or girdle the tree (see Control Options).
Red maple (Acer rubrum), hackberry (Celtis occidentalis), black gum (Nyssa sylvatica) and sassafras (Sassafras albidum).
