Cold Tolerant Palm List Since more and more people are becoming palm enthusiasts the world over, more information is being collected about certain palms. Some palms that were once thought to be not so cold tolerant are now being reported to be more adaptable to colder climates. We see many new palms thriving in Central Florida where these were once in the deep south or near the Equator only. The late part of winter 2009 we experienced 4 nights of shattering temperatures that hovered between 17 - 22ºF in our area. We feel fortunate to have had the low of 22ºF. Since I have always experimented with the palms and the tropical plants to determine what they can actually take before death, I left quiet a few out. Some were even in the green house and still were harmed with brown leaves, although the plants were ok. It was so cold for such a long period of time and unexpected that much of this industry suffered loses in the millions this past winter. That is very unusual for this area and is the reason for such a great loss to the horticulture industry. We have had weather of these temps many times in the past over the last several years, but not that I can remember where it was this cold, for that long a period extending for 14 hours straight more than 3 nights. The first night of the freeze hell of winter 2009, we took note of the 5" deep birdbath water being frozen solid by 9pm. I knew we were in for it then and there wasn't much we could do but pray, ride it out and hope for the best. We did get knocked down more than anticipated and now have to wait for many of the tropicals that usually don't get harmed to come back to life. That is happening as the warmer summer approaches. I don't know why they want to teach us about global warming, but it makes me laugh. I suppose the petition by 31,000 scientists in America to the government didnt make a difference to our congress or the fact that 30,000 of them are in the process of suing Al Gore for his Nobel Prize Winning revolution of Global warming. really makes me question what the Nobel Prize is all about? No matter, because they are going to say what they want as has happened for most of my life whether true or false on the issue of the day. Personally, ill take the Experts' word in all fields whether it be scientists' or medical doctors' over a politician's word any day. Some things were meant to stay out of the hands of government. Enough about that, I don't want to get into politics here. Most scientists are saying that were in for a cool down period for about the next 10-12 years as they taught my generation in high school. They were correct back then, we experienced what they said as it the climate change is a result of the different earth periods we have and will go through. it is natural according to real science. I REALLY hope that their prediction doesn't mean an even COLDER and longer winter next year. If it does, we will be prepared as possible. We will not be naive and remain thinking it wont happen again. 2009 = Lesson learned! So, with all that experience and with all the palms we used as guinea pigs, I will try to explain on this page what I learned from personal experience and expel the information about a few certain palm tree species and the cold tolerance they can endure. I'm going to treat any palm that will live through mild freezes and not die as cold hardy and place here (at minimum) what I know as max punishment for these awesome plants in the grass family. We will continue to add more known cold and colder tolerant palms as we get testimonies. If you have a testimony please let us publish it here. (click to email). Please feel free to send photos with your email. The larger, the better. Thank you for joining us. |

Known Cold Hardy Palm Trees
Green Mazari Palm - Cold Hardy to -3ºF degrees! Trachycarpus Genus: Known to tolerate cold Mini Chusan or Waggie Palm - Trachycarpus Wagnerianus
1. Pindo (Butia Capitata) or "Jelly Palm" - Zone 7b - Stands temperatures to 10º degrees F. These have been commonly reported to be living in southern parts of Georgia and in Louisiana with much success! 2. European Fan Palm (Chamaerops humilis) - Zone 6/7 - Stands temperatures to 5ºF degrees. 3. Saw palmetto (Serenoa Repens) Zone 7b - Stands temperatures to 5ºF degrees 4. Florida Sabal Palm - (Cabbage Palm) Zone 8 - Stands temperatures to 10ºF degrees at least 5. Mazari Palm (Nannorrhops Ritchiana) Zone 8 - Stands temperatures to 10ºF degrees 6. Sabal Minor (dwarf palmetto) Zone 7b - Stands temperatures to 5ºF degrees 7. Chinese Windmill Palm - (Trachycarpus Fortunei) Zone 8 - Stands temperatures to 10ºF degrees 8. California fan Palm (Washingtonia Filifera) Zone 8 - Stands temperatures to 10ºF degrees 9. Washingtonia Robusta - Zone 8 - Stands temperatures to 10ºF degrees 10. Triangle Palm - (neodypsis decaryi) - Zone 8a - Stands temperatures to 25ºF degrees before death, but leaves will become spotted - Ours small ones died in the prolonged harsh temperatures and were waiting to see if the large ones are dead. The large 15 ft triangle palm we had succumbed to the cold and died after prolonged freezes below 24ºF for more than 14 hours one night. It has withstood all the last 8 years of winter's short freezes and frosts. 11. Canary Island Date Palm (Phoenix Canariensis) - Zone 8 - Stands temperatures to 10-13ºF degrees with ease! 12. True Edible Date Palm (Phoenix Dactylifera) - Zone 8 - Stands temperatures to 13ºF Degrees with ease! 13. Senegal Date Palm (Phoenix Reclinata) - Zone 7b-8a - Stands temperatures to 11ºF sometimes lower depending on area and protection
14. Phoenix humilis - Mountain Date Palm - Zone 7b-8a - Stands temperatures to 11ºF sometimes lower depending on area and protection 15. Stone Gate Palm (Trachycarpus Princeps) - Zones 7 - 11 - Stands temperatures to 8-10ºF degrees! 16. White Elephant Palm - (Kerriodoxa elegans) - Zone 8-11 - They are not reported to be cold hardy by the experts, however, I have to add this because the ones that were left to the pure cold were not even touched in 22ºF temperatures. 14+ hours the first night and at least 5-6 for three more nights. This is the third winter we have owned them from germination and never have they been harmed by the cold weather.
More palms will be added to this page as time and knowledge permits - A work in progress. |
Since I do not know of any palms that will grow below minus 20 degrees, I'll start the chart at Zone 5
| Zone | Maximum low Temps Fahrenheit |
| Zone 5 | -20º to -10º |
| Zone 6 | -10º to 0º |
| Zone 7 | 0º to 10º |
| Zone 8 | 10º to 20º |
| Zone 9 | 20º to 30º |
| Zone 10 | 30º to 40º |
| Zone 11 | 40º and up |
