I have a young Euphorbia Pencil Cactus in a pot on the front porch at our getaway cabin in Gause (8b) Central Texas. It was a cutting from a friend's 5' plant. I have had it 2 years, it is 3' tall now and leafing incredibl. To date, I have carried the pot inside the cabin to winter over and move the pot back to the porch in late Spring. I understand these things can get huge if planted out in the ground and have a wonderful place there I want to move it to when it gets larger.

My question today is when it has been planted out directly in ground, on the southeast corner of our cabin porch (will get full sun until mid-afternoon in that spot), will it take a freeze? Central Texas gets about 4 hard freezes a winter on average, dropping below 32º, dipping to the 20's, even to the teens on the rare occasion. Will a pencil cactus in-ground take the below 32º temps (if large/established enough plant) or will it die? If it dies, do they come back off roots the next season? Or must these be totally protected, regardless of age and size, from any freezes?

I don't believe it will come back. It looks like the absolute minimum is 30 degrees.

The database here lists Zone 9a as the upper zone for Euphorbia tirucalli; it lists Zone 10a as the upper limit for Euphorbia tirucalli 'Firesticks'. Either way, I'd think Temple got too cold too often for it to survive a winter.

Thanks Donald and Hamwild. I was afraid that would be the answer. Most succulents don't like the cold. But man, I've seen photos of these with ginormous trunks and great height, which one would think would take colder temps. Guess I'll just have to let this one live in pots "until death do us part". Gause, where the cabin is (closer to Bryan/College Station) is farther south, but even they and clear to Houston get the occasional freeze. That's OK. I can do pots. It's happy in the porch spot where it lives and it's no biggie to move it inside each winter. I just had a white rain downspout on that corner of the porch I though this plant might help hide as it got up to tree height. Guess not. Sighing!
