European mistletoe (Viscum album) was established in Sonoma County about 90 years ago and has spread a maximum of 7.5 miles and an average of 5 miles from its point of introduction in Sebastopol. The mistletoe now occurs in the nearby communities of Graton, Santa Rosa, Fulton, Cotati, Forestville and Occidental. It has been found on 23 different deciduous trees, but is most common on silver maple, apple, black locust, red alder and Fremont cottonwood.
