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?
