Phoradendron serotinum is a type of parasitic plant commonly known as "mistletoe." It is typically found growing on hardwood trees such as oak, hickory, and maple. While mistletoe is often associated with the holiday season and kissing traditions, it also has a variety of medicinal uses. Synonyms for phoradendron serotinum include "American mistletoe," "oak mistletoe," and "downy mistletoe." These names all refer to the same species of plant, which has green leaves, white berries, and a bushy appearance. Despite its reputation as a holiday decoration, mistletoe should be handled with caution and not ingested, as it can be toxic in high doses.
