I have over 10 Sabal minors that are all doing great. My largest minor is a Louisiana variety and is pictured below. I bought it in 2010 as a 1-gallon. I moved it to its current location in 2016 and it took the transplant with no issues. I've been getting hundreds of seeds off this plant for quite a few years now. I've got some potted seedlings that I plan to either give to friends or put other places in my landscape. I don't protect any of my minors in the winter besides giving them a good layer of mulch.
My Trachy has been in the ground since 2016 in an excellent microclimate where it stays a few degrees warmer and isn't subjected to much wind. It took some pretty good burn the past few winters, but has come out great. It hasn't flowered yet, but is pushing up multiple spears each summer. The most protection I offer this plant is a wrapping of tarps/blankets if we see lows in the single digits. It could probably survive those temps, but I try to preserve as many green fronds as possible. Other than that, this guy takes our winters with no issues.
Here's some pics:

Another of my minor McCurtains. These definitely go slower than the Louisianas, but I love having them given that I'm only a few hundred miles from their native range in SE Oklahoma.
Here's my in-the-ground Trachy. I wrap this up with tarps and blankets once or twice every winter if we get down below 10 degrees, but other than that, no protection. It's really taken off this summer and put on a good four or five healthy new fronds.
Potted Saw palmetto with Purple heart ground cover. Not quite brave enough to try this guy in the ground, but at some point I might. The purple heart is a great ground cover that easily over winters for us here.
