Brodiaea coronaria grows as far north as British Columbia and is 
bone-hardy as far as I am concerned. Our winters are *usually* mild, 
but every so often we get an "arctic outflow" of extremely cold air. 
Februrary 1989 is the last one that was really memorable; the soil 
froze a foot deep in some places.

Brodiaea coronaria doesn't turn a hair at these cold snaps.
