Mine has never seen 26 and hope it never does but I think they should take that well unless there are several hours of freezing with frost. Mine has taken around 30 degrees one time and had minimal damage to two fronds that had frost for two hours.

A potted specimen on my front porch saw two nights in the mid-high 20's. The older fronds have some damage, maybe as much as 20% of the tissue browned. Overall I thought that was pretty good. I feared it might die. Not sure how much frost formed on the leaves, but I can say it's common for light frost to form on this plant and it generally shows no damage. Now in June, (4 months later) new growth has resumed.

Summers are great, 90f/32c in the day & 70f/21c at night with plentiful rain & sun

Winters are subtropical with occasional frosts and freezes. Tropical cyclones happen.

We have a few Royal palms in the warm microclimates but Coconuts freeze.

Mine was unaffected by 26 degrees with no frost (report from nearby airport) followed by 28 a couple of weeks later. It's under a bit of canopy and next to Sabal minor. The Coccothrinax is trunking, so I expect it to grow over the Sabal in a few years.

Encouraging find with this species. Left a few very small  2 to 3 leaf seedlings in Dixie cups out in multiple nights of freezing temperatures with a ultimate low of 22-23 and another couple nights in the upper twenties. Still look the same with zero freeze damage. Will update if they suddenly croak but so far they seem to not have been affected.

I must have a native Florida strain because I highly doubt seedlings from a Caribbean strain would survive what these were exposed to and the time duration of below freezing temperatures.

Potted specimen, 4 years from seed (~2 feet overall) collected from habitat in Bahia Honda Key.

28˚, no frost. No damage.
