Beccariophoenix alfredii cold tolerance?

[Jhferral]

I was told these palms were cold hardy. 

Mine froze after a few hours at 30 degrees.

Anyone else experience this?

They seem to be a lot less cold Hardy than what people say there's a post on palmtalk about it https://www.palmtalk.org/forum/topic/41583-promising-news-for-beccariophoenix-alfredii-cold-tolerance/

They're not very cold hardy before they get some size on them.  You didn't say how big your palm is or when it was planted.  First winter in the ground usually requires some protection from a freeze.  My alfredii juvenile (not yet fully pinnate) planted in 2025 had zero damage at 27°F in a radiational freeze covered with a tee shirt.

This is the issue with vague terms like cold-hardy.  Hardy to what temperature what percent of the time under what conditions?  If it was a typical radiational freeze down to 24F, Beccariophoenix alfredii would probably have a lot less damage.  Add in 40mph winds the first night and several frost events after that and we got different results.  A lot of the Becarriophoenix alfredii here are bronzed from the combination of wind, cold and frost.   Mine was in an area where the other plants in the yard cut the wind speed down to 13 MPH and had minor burn.  Beccariophoenix fenestralis is growing, but it was completely defoliated from the same event.

This event will undoubtedly produce tons of observations for the Cold Hardiness Observation Master Data.  That said, I'd rather have less observations and more palms.  Hope that the palm(s) in question recover, but be wary of terms like cold-hardy that don't offer many specifics.  The record lows along the I-4 corridor generally range from 15F-20F.  That holds true inland the entire way down to Immokalee.  Those temperatures can kill a lot of palms considered cold-hardy.
