Jane, etal:

We tried several of the Princess series of Alstromeria, and found 
Alstroemeria 'Stapripal' to be the hardiest.  We have grown this in the 
open garden for 9 years and it flowers reliably each year.  During this 
time, we have only seen a winter low of 6 degrees F.  Unfortunately, the 
introducers choose to thumb their noses at the International 
Nomenclature Code and US Trademark law in the naming of the plants.
