oak mistletoe

Oak mistletoe, scientifically known as Phoradendron serotinum, is a type of parasitic plant belonging to the mistletoe family. These plants are hemiparasitic, meaning they contain chlorophyll and can produce some of their own food, but they also draw water and nutrients from a host tree through a specialized root called a haustorium. Oak mistletoe commonly grows on deciduous trees, including oaks, and is often visible after the host tree loses its leaves in the fall and winter. While mistletoes are used as festive decorations, especially around Christmas, they can be considered pests as they can deform branches and reduce a host tree's reproductive ability. The berries of mistletoe are toxic to many animals and humans.12
