Mistletoe is a common plant throughout North Carolina that can be found growing on the branches of deciduous trees. This same mistletoe is.

It commonly has two or even four embryos, each producing its hypocotylthat grows towards the bark of the host under the influence of light and gravity, and potentially each forming a mistletoe plant in a clump.

Possibly as an adaptation to assist in guiding the process of growing away from the light, the adhesive on the seed tends to darken the bark.

On having made contact with the bark, the hypocotyl, with only a rudimentary scrap of root tissue at its tip penetrates it, a process that may take a year or more. In the meantime the plant is dependent on its own photosynthesis.

Only after it reaches the host's conductive tissue can it begin to rely on the host for its needs. Later it forms a haustorium that penetrates the host tissue and takes water and nutrients from the host plant. Some species of the largest family, Loranthaceae, have small, insect-pollinated flowers as with Santalaceaebut others have spectacularly showy, large, bird-pollinated flowers.

Most mistletoe seeds are spread by birds that eat the 'seeds' in actuality drupes. Quite a range of birds feed on them, of which the mistle thrush is the best-known in Europe, the Phainopepla in southwestern North America, and Dicaeum of Asia and Australia. Depending on the species of mistletoe and the species of bird, the seeds are regurgitated from the crop, excreted in their droppings, or stuck to the bill, from which the bird wipes it onto a suitable branch.

Although mistletoe is an evergreen shrub that is capable of performing photosynthesis, producing 98 percent of its own food, it sends rootlike structures called haustoria -- the singular form is "haustorium" -- deep into poplar branches where they rob the tree of its water and nutrients.

As an obligate parasite, mistletoe has a dependent relationship on its host tree -- it cannot survive if the tree dies. Trojan Horse Mechanism Mistletoe has a botanical Trojan horse relationship with its host tree. As a result, the tree continues to deliver water and nitrogen through the branch, which the mistletoe pilfers. Mistletoe also releases growth-regulator chemicals that imitate those of young tree tissue.

The tree responds by sending additional nutrients to nurture the needs of its perceived new growth.
