Not really a gardening question, but looking at some mistletoe in local
gardens made me think. It is an evergreen, but in the UK uses deciduous
trees/shrubs as a host. I wondered how it survives when the host is
dormant for so long. It is said that evergreen trees and shrubs can
survive cold weather very well providing their roots are not frozen. But
mistletoe must have frozen "roots" if the host branch is frozen, so how
does it deal with that situation?

Or have I got that completely wrong?

This got mentioned in today's 'Home Planet' on BBC Radio 4
