Mistletoe is a group of parasitic plants found worldwide, with European mistletoe (Viscum album) and American mistletoe (Phoradendron serotinum) being the most famous. Known for its green leaves and white berries, mistletoe grows on tree branches, siphoning water and nutrients from its host.

How Does Mistletoe Survive?

Mistletoe employs unique survival strategies:

1. Parasitism
   Mistletoe attaches to the branches of trees and shrubs using specialized roots called haustoria. These roots penetrate the host’s tissues, drawing nutrients and water to sustain the mistletoe.

2. Photosynthesis
   While mistletoe relies on its host for sustenance, it’s partially self-sufficient. Its green leaves allow it to perform photosynthesis, producing some of its food.

3. Bird Allies
   Birds, particularly species like mistle thrushes, play a crucial role in spreading mistletoe seeds. After consuming the berries, birds excrete the seeds onto tree branches, where they germinate and begin their parasitic journey.

4. Winter Resilience
   Unlike many plants, mistletoe remains green in winter, thanks to its evergreen nature. This characteristic makes it a symbol of vitality and resilience during the cold season.
