I'n in south central Virginia, Vernon Hill/Halifax area, right at the North Carolina line, so we get dips but at this time of year we are starting to hold steady at 60 degrees at night.
I have 2 dragonfruit that bloom and ripen fruit and they are usually right next to the plumies, they don't get any different treatment except their pots host dahlias too. Maybe the trees want pot buddies, lol!
