Nature table: What do you know about mistletoe?

Mistletoe is an unusual plant, to say the least. 

It’s a parasite growing on deciduous trees such as apple, birch, lime and oak. It sucks sap from the host tree, often damaging it but seldom killing it.

But mistletoe has evergreen leaves that can photosynthesise so it can produce nutrients of its own, particularly during winter when its host tree is dormant.
