Viscum album was introduced in about 1900 into an area north of San Francisco, California. By 1984, the gross area covered by the parasite had spread to about 114 sq. km.

Viscum occurs on at least 22 hosts in California, the most common are Acer saccharinum, Malus sylvestris, Robinia pseudoacacia, Alnus rubra, Populus fremontii , and Salix lasiandra .
