Greg, Funny you mentioned PNW cause i moved to CA from 2 years of living Spokane, WA and let me tell you my semps froze their little "rosettes" off. There was a nite there in Oct that reached 4 degrees and I was piling all the shade cloth and N-sulate cloth I could find to protect them. Of course in Spring I lost a lot of them when 30% of them bloomed.
