Remember To Acclimate Your Palms
Getting Good Advice
If you look in a typical palm book, you will see statements such as “this species is well suited for temperate areas”. What does that mean in your case? Its not very helpful. Words like temperate and semitropical and mild areas are sometimes more deceptive than helpful. Yet these are the types of statements palm books make about growing different palm species. All you want to know is “will it grow for me?”
Nursery staff assist customers in finding the best species for his area To answer this question for you, a palm grower depends on his experience and the experience he’s gathered from others over time. For the past 35 years I’ve gathered cold tolerance information from my customers, my own growing experience, Internet discussions, and from meetings and conferences I’ve attended. The knowledge that experienced growers attain becomes almost second hand to them. The Palm Society of Southern California has, for years, pooled information and produced a publication about cold tolerance of many species. The usefulness of this information is to let us all know which species have the best chance to survive in one’s garden, especially if he lives in a very cold area.
Therefore, when you know how cold you get, talk with a palm nurseryman, an experienced palm enthusiast, or someone who really knows his stuff. This will keep you out of trouble and make your growing a lot easier. Unfortunately, home improvement centers and general nurseries typically don’t know much about the species and specifically about their cold tolerance. Most palm specialty nurseries will know which species are best for your area. It might be wise to trust their opinions and recommendations.
Be Realistic - Once you are armed with information about your cold weather and have a reliable and informed nurseryman for your plant material, pick the appropriate species for your area. I can’t tell you how many times a customer has enthusiastically told me that their particular area is a “special microclimate” and that they can grow things no one else can grow. Perhaps this is true, but palms show very predictable damage when exposed to certain temperatures. Certainly there are a lot of variables but Don’t expect the impossible. Be realistic in your expectations.
Cold Hardy Palms - The Best Palm Tree Species for Cold Weather
THE BASICS ON LEARNING WHICH PALMS WILL TOLERATE YOUR WEATHER - SELECT THE BEST COLD TOLERANT SPECIES
by Phil Bergman
Cold hardy palms - the best palm trees species for cold weather - is described here. There are a couple of basic things to consider when selecting cold hardy palm species to grow in your locality. First is to know how cold you get. Second, learn the cold tolerance of the various species. The final thing is to learn how to give your palms good culture and cold protection if needed. This applies to periods before, during, and after the cold weather.
How Cold Do You Get? The Most Important Question
When you select palm tree species to grow, realize that your coldest night's low temperature determines what you can grow. You should begin to know and have your low temperatures on the tip of your tongue. The major limiting factor in the successful growing of palms is the degree of cold weather that any given palm species will see during the winter. Factors such as intensity of sun, presence of summer heat (or lack of it), and humidity are also very important. But, cold exposure is the most limiting factor. So, the goal is to know how cold you actually get on the coldest nights. Try to get a maximum-minimum (high-low) thermometer. Most palm nurserymen would rather you tell them your low temps than quoting “climate zones”, as the latter are unreliable and quite variable. The best way to determine how cold your garden gets is to purchase a maximum-minimum or hi-lo thermometer. They are quite simple to use. Place it in the garden in the shade. Although you can reset it with a magnet, it might be best to just leave it alone for the lowest temperature over a longer period.
When you go to buy plants, the most valuable information you can give to a nurseryman is "how cold you get". It'll make his recommendations easier and save you losses on a cold winter.
In Our Area Certain Palms, Including the Coconut Palm, Do Not Survive Outdoors
Yes, there are a few survivors throughout the entirety of Southern California. But, as a very reliable rule, Cocos nucifera, will eventually die in Southern California from our cold weather. This doesn’t mean you cant try, but the chances are you will fail. The same applies to a lot of sought after species. Cyrtostahcys renda, the Red Sealing Wax Palm, attracts many enthusiasts because of its dramatic red trunks. No, it will not survive in cold weather. It predictably dies at about 47 degrees Fahrenheit. Archontophoenix cunninghamiana, the King Palm, dies at about temperatures below 24 to 25 degrees. The typical Queen Palm dies at about 18 degrees. So, if you know your garden gets down to 5 degrees, don’t think you’re going to keep alive any of the above species. Plant palms that will predictably grow in your area. If you like to make lists of palms that appeal to you (typically on the Internet or with books), bring that list to your local grower and he can tell you which ones to eliminate. Many of our customers do just that. Some specifically are searching for cold hardy palms. If they aren’t sure, they might bring in a list of twenty-five plants, and we immediately eliminate some because they probably wont survive in his area. Remember, the first things I ask a new visitor to the nursery is “where do you live and how cold do you get”. Below are two palm species you may not be able to grow.
What About Microclimates?
It is true that microclimates are very important and do exist. Being on a ridge is better than being in the bottom of a cold valley. Overhead canopy is also protective from the cold. Such canopy can keep interior garden temperatures much warmer on a cold night, sometimes even 10 degrees F. warmer. Large rocks jutting out of the ground can maintain the previous days warmth and release this warmth during the night. Morning exposures to sun can quicken the re-warming of the plants after a cold night. All of these things are important. But, the cold that you measure (even in the microclimate areas) is the low. This determines which species you can grow. Another recommendations is to look around in your area. If your neighbors tell you that a given species has died in the winter despite three attempts, perhaps that species is bad for you. On the contrary, if people in your neighborhood are growing well a given species, the chances are you can grow it as well. Except for the rare “warmer” individual microclimates, most neighborhoods share a similar low winter temperature. Cocos nucifera, a poor choice for all but the most tropical areas.
How To Use This Information
Use the following cold tolerance information as a general guide.
There is no crystal ball in the plant world. The following information will help you pick the right species for your area. But, it is not gospel. It is not a guarantee. It is meant to be helpful information only. With this in mind, please read the next session.
The next section of this article is where I discuss the species and which would be right for you.
Palms for the Coldest Areas
Palm Trees For
Extremely Severe Cold Weather
F. and lower)
Although a comprehensive list of all species is not possible here, there are many palms that do tolerate some degree of cold.
We shall break it down into three groups: Palms for extremely severe cold weather, palms for moderately severe cold weather, and palms for cold weather with definite freezes. Obviously, plant species from a colder group would be grown easily by people who find themselves in a warmer grouping.
Remember that it's all about your lowest temperatures, not your climatic zone
Butia capitata: A blue-green colored pinnate palm of medium stature with a stout trunk and re-curved pinnate leaves. Known as the Pindo Palm or the Jelly Palm, Butia capitata can tolerate temperatures slightly below 15 degrees. I’ve just had reports of no damage to 12 degrees.
Brahea armata: A large, single trunk silver-blue leafed fan palm that tolerates heat, cold to about 15 degrees, and arid conditions. Known as the Mexican Blue Fan Palm, this species is slow growing and tolerates xerophytic conditions. More recent reports show definite leaf damage at 15 degrees F.
Chamaerops humilis: A green to silver-green fan leafed, suckering palm that gets to about 15 feet. It tolerates dry, arid conditions and temperatures to about 5-10 degrees. Common name is Mediterranean Fan Palm.
Jubaea chilensis: A very thick trunked, tall pinnate palm known as the Chilean Wine Palm. Known to be very slow growing, it can tolerate inland sun and a good deal of cold, probably to about 16 degrees. You plant this one for your kids because its so slow growing. Very valuable when mature sized
Jubaea X Butia: This is an unusual hybrid, often grown as an F2 hybrid from existing mature specimens. It gives one a fast growing plant with a trunk almost the size of a pure Jubaea. Reports are that this hybrid tolerates temps down to 14 degrees F. It has a thick trunk and is much faster growing than pure Jubaea
Nannorrhops ritcheana: A suckering, small (to 12 feet) attractive fan palm that has green and blue forms. This clumping palm tolerates hot sun, dry conditions, and temperatures to about 16-17 degrees or slightly lower.
Rhapidophylum hystrix: Probably this species is the most cold hardy of all palms. It is a small to medium sized, suckering fan palm that will grow in sun or filtered light. It will tolerate under 0 degrees F.
Sabal bermudana: This is a large trunked, full sun species that will tolerate temperatures to about 15 degrees F. It has a full head of leaves and gets to about 20 feet. It likes full sun and heat.
Trachycarpus takil: A single trunk palm similar to T. fortunei but a bit taller with deeper splits in the leaves. It should tolerate 5 - 15 degrees, but more feedback is needed. Photo by TS & MG

This is where your palm grower comes in. All are beautiful, all are fans, and most are medium sized. Good ones for 28 degrees include P. affinis, remota, minor, and a few others.
The Cherry Palm is slow growing. When I say slow, I mean slow. But, because of its unique bulging trunk, silver colored crown shaft, and gorgeous overall appearance, it is worth the wait. Cold tolerance to 28 degrees. Likes full sun and to be put in the ground.
This species is similar in appearance to P. elegans, but has a few key distinctions. It is more stout, with a thicker stem, leafs and petioles. It is more sun hardy and also seems to be more tolerant of cold and heat. Ultimate height is unknown, but is probably close to 20 feet. Hardiness is about 24-25 degrees.
Ravenea glauca: A rather small Ravenea with a trunk about 4 inches in diameter and a height of about 20 feet. Very dainty and pretty. It takes down to about 26 or 28 degrees and likes sun or filtered light. Photo by unknown author c/o Palmpedia
Ravenea madagascarensis: A somewhat silver tinted pinnate palm with a thin trunk and a preference for full sun. Crown shafted. Takes to about 26 degrees.
Ravenea rivularis: The Majesty Palm is a thick trunked, fast growing pinnate palm that likes water, nutrition, and room. It looks best in AM sun, not full sun (unless you’re a good grower). The girth gets quite large. Takes to about 27 degrees.
Rhapis humilus: This gorgeous suckering fan palm is a knockout. It gets quite tall (to 16 feet), prefers filtered light, likes moisture, and is very exotic. Its miniature cousin, the related palm Rhapis multifida, is just as gorgeous but smaller. Both take down to about the mid to lower 20’s F.
This is a very slender and graceful lady palm type. It is shorter and less sun hardy than R. humilis, but is cold hardy into the mid-20’s. It’s dainty growth habit, clean fiber and finely divided leafs make this an exceptional and elegant addition to any garden. Max height of 8-10 feet.
Rhopalostylis bauerii: A very attractive crown shafted pinnate palm that prefers filtered light, though many people grow them in sun coastally, and is from New Zealand. It is somewhat slow growing, single trunked, and tropical appearing. This species gets approximately 20-25 feet in Southern California. It takes down to 24 degrees, a bit lower than the Kentia Palm.
Rhopalostylis sapida: The Shaving Brush Palm or Nikau Palm has similar cold tolerance as the R. bauerii, but takes more sun. It likewise is slow growing but worth the wait. Every palm enthusiast must have one. Plant in filtered light unless you’re right on the coast.
This is the Puerto Rican Royal palm. It is shorter and thinner than it’s Cuban counterpart, but is equally and perhaps more cold hardy. It is a fast grower (to 40 feet) and is tolerant of costal winds in California, which the Cuban Royal is not. This species is hardy to 24-25 degrees.
Roystonea regia: This is a drop-dead beautiful, single trunked, crown shafted pinnate palm with a large grey trunk with bulging at the base. It takes down to about 26 – 28 degrees or colder and gets very tall. It demands full sun. Persistent cold can cause its demise. More recent experience might suggest that Roystonea borinquena has a bit more cold hardiness than R. regia.
Sabal species: There are lots of Sabals worthy of trying that can take down to 28 degrees or lower. All tend to be large, although some are small. All are fans and like full sun. Sabal bermudiana is quite large with huge leaves; Sabal causarium has a thick trunk and gets very tall (may tolerate down to 20 degrees); Sabal etonia is near trunk-less and likes full sun; Sabal mauritiformis (the Tropical Sabal) is very gorgeous with a full circle leaf; Sabal rosei is quite large and has re-curved leaves; Sabal uresana is blue and a knockout. There’s lots more Sabals, and some will take into the mid teens. Talk to your palm nurseryman.
Syagrus coronata: A medium sized, sun loving pinnate palm that doesn’t look like a Queen Palm at all. Very unique and single trunked. Cold hardy to about 26 degrees.
Syagrus sancona: This is a much larger species that approaches the size of the Queen Palm. It has a thick trunk, pinnate leaves and is quite beautiful. Cold hardy to about 27 degrees.
Syagrus schizophylla: A unique Syagrus that is smaller than the S. sancona and can be grown in sun or strong filtered light. Takes down to 28 degrees.
Synecanthus fibrosa: Single trunk, pinnate, understory with irregular widths to the leaflets. Gets up to about 10 feet and takes down to 28 degrees.
Trachycarpus species other: There are multiple new to the market Trachycarpus that take 28 degrees or colder. Try species like T. martianus, nanus, oreeophilus, latisectus and others to have some fun. All are fan palms and like sun or strong filtered light. Most are small or medium sized. photo by R.
Wallichia disticha: A unique feather palm with matting on the trunk and a single plane arrangement of the leaves. Its fat from one side, thin from the other. Looks like a Caryota. Cold tolerance to about 28 degrees. Its cousin, W. densiflora is also about the same cold tolerance, but this species suckers.
Wodyetia bifurcata: The foxtail palm can take down to about 24 degrees. Cold weather can show tip burn, but the tree often survives. It is single trunk, pinnate, likes full sun and lots of heat, and should get to about 25 feet. Well grown, it is a knockout!
This is known as the “foxy lady palm”. It is a hybrid between Wodyetia bifurcata and Veitchia joannis. This is a gorgeous and fast growing palm. It gets about 25-30 feet and is hardy to about 25-27 degrees.
Palms For Minimum Temperatures Above 28 Degrees:
Count your blessings, for there are a lot more species you can grow. Certainly, any of the above are for you, but you’re going to have some real fun because the list expands dramatically.
What To Do If You’ve Suffered Cold Damage
Here in Southern California, in 2007 we had one of the worst freezes in 60 years. People have reported damage to palms that have been around for decades. Farmers in some areas have lost the year’s crops. It’s frustrating for all of us. But, there’s an optimistic side to all of this. Except in the hardest hit areas, most palms came back. Some were lost. This once again emphasizes the basics when you plant palms. Be realistic in picking the right species. Uninformed purchases from large depot type stores without proper guidance may result in losses. Plants grown in warmer areas outside of your area and then market to you might not withstand your cold weather. To avoid these problem, support local nurseries near you and get their advice.
If you have a palm that’s been damaged by cold, there are things to do and inspect to see what your plant’s future might be. Everyone notices the discolored and browned leaves. Burn can be a faint yellowish-brownish discoloration or, if severe, a dark chocolate-brown or black discoloration. This may become more apparent as days or weeks proceed. So, if you see this, how can you see if the plants going to make it? You check for evidence that the palm is still growing. Here’s how:
1. Look at the new spear coming out of the crown. Is it green and healthy looking? (good sign). Is it a mixture of green and brown? (worrisome but better than totally brown). Is it totally brown or black? (very worrisome) Is it mushy? (bad sign) Does it pull out with a gentle tug? (bad sign)
2. Is the crown of the palm below the spear firm and hard? (good sign) Is it mushy or soft? (very bad sign).
3. Is the trunk collapsing or showing vertical indentation lines? (very bad sign). Is the trunk leaning over or bending? (get the shovel out).
4. Are some of the older leaves still green despite the spear looking bad? (probably of no importance. It’s the spear and new growth that count)
5. Is the new growth spear emerging out of the crown? (most important good sign). Measure this by holding an older leaf petiole right up next to the spear and with one stroke mark both horizontally with a magic marker. This shows you where the spear is right now. Then inspect it in a day or two to see if the spear is emerging or moving upwards. If it is moving out, that shows promise. It’s no guarantee the palm will live. But, if after a few weeks there’s not a millimeter of movement, that’s not good.
There are exceptions. Spears can pull out and occasionally the plant will live. There can be spear growth and yet the plant goes on to die. A plant can stall for some time and yet still recover. But, these inspections above are indicators of what’s to come. Remember to give prophylactic fungicides down the throat of the plant when you see cold damage. Although no studies I’m aware of document it’s benefit, most growers advise this treatment. Possible fungicides to use include copper based fungicides and another named Daconil ( Chlorothalonil ). It might be marketed under different names, so ask for help when purchasing. Always use protective gear when spraying pesticides.
This is the opposite hybrid to the “mule palm” (Butia X Syagrus). It is a bit more queen-like in appearance, though it certainly has Butia features. It is slightly less cold hardy, about 18 degrees and has a thinner trunk usually. This species is great for sun and heat and will eventually get 25 feet or so.
This hybrid is strikingly beautiful and is quite hardy. It is great for sun and heat and is often grown in desert and harsh climates. It is called a “Mule Palm” as this intergeneric hybrid generally does not produce viable seed. They get about 25 feet tall,
Serenoa repens: A dwarf, suckering fan palm that is typically green in color, but occasional blue-colored varieties are available. It will tolerate down to 10 degrees.
This is a very hardy species. They can take down to 10-12 degrees. As you can see in the photos they are quite full and lush. They are native to the Southern states (various cultivars), but are commonly recognized as a Floridian native. This species is also very heat tolerant and can get up to 30 feet or bigger eventually.
Sabal riverside: A blue-green, large fan palm that tolerates hot sun and is quick growing. It is probably a form of a Caribbean Sabal that just happens to take cold quite well. Recent reports are this species does well at 12 degrees F.
Sabal species (hardy):
Other very hardy Sabal species that should take 15 degrees or lower include S. etonea, minor and causarium. These species vary in height and appearance, but all seem to be heat tolerant as well. Photo by Wikipedia.
Trachycarpus fortunei: A single trunk, medium height fan palm with a hairy trunk and nice full head. Known as the Chinese Windmill Palm. It will tolerate temperatures down to about 5 degrees.
Washingtonia filifera: A large single-trunked, tall fan palm that loves the hot desert areas and tolerates temperatures to about 15 degrees or slightly colder. Note that Washingtonia filifera is definitely more cold hardy that it’s sister, W. robusta.
