Barb and Tim: I have protected the McCurtain with some mulch, dry leaves, and a recycling bag. My goal is not to have to heat any outdoor palms 8)

I have not seen a noticeable difference in any of the sabal minor species exce[pt for 1 variety I purchased in North Florida where it gets down to -11C this species has been in the garden for 3-4 years now. I have 1 near the foundation a 1 far from the foundation with a rose cone cover that's it. I am experimenting with sabal minor louisiana in the 3 gal size I have high hopes. Will keep everyone posted on that
cheers

While we all know I love these palms, I am very sceptical about using -30 C in marketing. I am not saying it didn't happen, once, somewhere, but still. I saw for myself that seedlings in the wild shrugged off -15 C with
no snow cover, and would be comfortable with a claim of -20 C. Not -30 C.

I agree -30C for a seedling doesn't seem possible. The sabal minors that I tested were 7 gal in the past and a large 3gal . but I did have some young seedlings fry at -13C
