Tom in Tucson 311 Report post Posted January 13, 2016 Although there is some data already compiled here, I think it is simpler to look up each species or hybrid separately. 27.7°F - no damage after 3 weeks. One in the ground (2 gal.) and a 1 gal. still in the pot. Both without any canopy or other protection.

TexasColdHardyPalms 3,230 Report post Posted February 3, 2016 I'll repost my Data Now that I have three different Trithrinax species. T. Campestris: Tiny 4" liners - 17 degrees without snow or ice, just fine, no spear pull on any plants. No burning of the leaves. 50 days later the same Tiny 4" Liners - 4 days in a row covered with ice and snow highs 32-36degrees, lows around 24-28 spear pull on 50% of the plants with bronzing of most of the leaves. 85% of the plants pushed new spears. 15% of them died. This is from a sample of 62 plants. 2G - no spear pull during either event and very minimal bronzing. Absolutely no overhead protection whatsoever. 3 Quote Share this post Link to post Share on other sites
