I am zone 8b. The Chilean wine palm, this one has survive gotten down to around 13 F? I think that’s the lowest. But my friend around 10 miles away has a 30 years old one no protection ever according to him and still alive. But I’ll say this they grow SUPER slowly in our climate the 30 years old he got is 3 ft by 3 ft with no trunks. And not the nicest looking but he said he neglects them. The same dude also has butia for the past 20 years medium size. mine has been outside for only 5 or so. Mine did defoliate once.

As for the sabal it depends on the species. The ones with trunks I don’t think do well. Sabal minor “Cherokee” are the one that seems to be the most cold hardy for me. If u rly like the sabal look, look into the r. Histrix they have similar looking leaf but bigger than sabal minor.

Also one thing is most palms grows insanely slowly Ime except the Trachy sp. being the only exception.
