I find this surprising also.  Perhaps the purpurea haven't been terribly 
hardy because you don't get the deep snow cover that they receive in 
their native range?  Snow is an amazing insulator.  I once killed some 
purpurea by trying to winter them in a garage which was attached to our 
house in Ottawa Canada (part of their natural range).  I figured the warmth 
from the house would make for a relatively mild winter.  It did when 
dealing strictly with air temperatures, but in the garage they of course 
had no snow cover for insulation and froze so solidly that they were dead 
as doornails in the spring.
