My comment here is that I think that Arno may very well be right--until t=he
temperature goes below freezing and stays there for a while.  Any water i=n
the plant tissues is going to expand, become crystalline,and destroy the
surrounding tissues unless there is sufficient glycogen or other
Europeans, unless they are Muscovites, seem not to appreciate this
limitation for many Americans.   Looking at a map is very misleading beca=use
many places in Europe are further north than, say, Chicago, with London,
England being at roughly 52 N, Aberdeen at 57 N, Oslo at 59 N..  But the
Chicago area is much harsher and unforgiving  in some winters than
Anchorage, Alaska.   Fully hardy in the U. K. or the Netherlands is often
"tender" in the Chicago area.

Local weather records are a better guide. Records for parts of Sikkim,
various elevations in Nepal, Yunnan, Guizhou  can be had on the web, not
always by using a search engine for weather data, or climate information,
but also travel agencies that may specialize in knowing the weather for
their  tourists.  Using more than one search term can deliver better
information.For example, instead of Nepal, try a local designation,e.g.,
Modi Khola Valley.   At 3000 meters it may be warmer and more sheltered t=han
Chicago in a cold year.

What Arno can "get away with" won't work for me, most years and just a bi=t
of thinking (with the right data) should make this clear to me.
