None of them will tolerate frost or a freeze . If I were you, I'd bring them inside before cold weather sets in.

Actually, all will tolerate frost.. .but none deep freeze. Portalacaria is good down to about 24 without damage, that Pachypodium about down to 28F and the Euphorbia about 30F. Of course, the length of time spent at each of these temps is important⦠I am speaking of a very short exposure and then it warms up⦠if you keep these plants at that time for even a few hours, more damage will occur.

I live in Maine. None would survive the brutal winter outside here. I take all of my tender succulents and cacti inside before the first frost.lol

I should have been more clear. I don't intend to let them go below freezing. The night time lows are dipping into the 40's and then warming up to the 60s and 70s during the day. As long as the forecast is above freezing, I leave my Jades and a few cacti outside. Once frost start, they come in for good. I was concerned about how the listed plants would take low 40s and high 30s. It sounds like they can take the same temps as the jades?
