Good question. Sub tropical location. But high elevation and micro climate that included morning and evening sun blocked by two mountain ranges. Helps me to get short days. And cool climate. But not constant 40s in the winter. Between zone 10-9. Overnight will drop down to mid 30's at the coldest but days back up to 60-70 range.
Right now they are going dormant pitchers drying up. Phyllodia forming. Everything slowing down. Purps slow down and don't lose pitchers
