Mistletoe species grow on a wide range of host trees, some of which experience side effects including reduced growth, stunting, and loss of infested outer branches. A heavy infestation may also kill the host plant. Viscum album successfully parasitizes more than 200 tree and shrub species. [citation needed]
Phoradendron tomentosum, the leafy mistletoe, hairy mistletoe or Christmas mistletoe, is a plant parasite. It is characterized by its larger leaves and smaller berries than dwarf mistletoe . Leafy mistletoe seldom kill but they do rob their hosts of moisture and some minerals, causing stress during drought and reducing crop productions on fruit ...
Mistletoe is a common hemiparasite of trees and shrubs. Toxicity varies by species, but all parts of the plant, especially the leaves and berries, contain an array of toxic chemicals, including several different viscotoxins , the alkaloid tyramine , and a ribosome-inactivating lectin called viscumin.
Mistletoe grows on trees. Money might not grow on trees, but mistletoe sure does. It's most noticeable in winter growing on bare branches at the top of a tree. What you might think is a nest of ...
In fact, according to Dr. Tina Wismer, senior director of toxicology at the ASPCA Animal Poison Control Center, the type of tree mistletoe grows upon affects the plant’s toxicity.
Severe colonization of mistletoe can affect the health of an individual tree, and a tree already stressed by other factors can be killed. Forest fragmentation can increase Phoradendron infection rates in some oak trees, as trees in lower density forests and those closer to the forests' edges are more likely to be colonized by the mistletoe.

The berries of the mistletoe do not contain phoratoxins, making them less toxic compared to other parts of the plant. The toxicity of the mistletoe is dependent on the host tree, since mistletoe is known to be a semi-parasite. The host tree provides fixed inorganic nitrogen compounds necessary for the mistletoe to synthesize phoratoxins. [2]
