we have a system for plant hardiness here in Norway.
In the list's discussions and at other places, some hardines zones are
described. I have tried to spot an explaination of this system but have not
found any. I understand in the USA, you use USDA's system.
Our system in Norway is zone 1 would grow only in very well exposed
zone 6 and up are extreme polar and mountain conditions.
