Washingtonia Species, Mexican Fan Palm, Skyduster, Washingtonia Palm

Vigorous, fast growing with attractive reddish leaf bases, this palm gives the signature "Hollywood Californian" look. For this reason, t...Read Morehe Mexican fan palm tree is planted avidly throughout it's range.

I've seen other resources list zone 8 as the northern most growing range. And from my experience, I would only correct this statement to say that it is hardy in zone 8b with protection.

The fronds seem to start burning in the low 20's. Through the 8 winters I've been here, only 3 have had temps that got into the teens. With a winter this hard, unless the tree is fully mature with a full crown, there is a good chance it will be killed. Even still, I have seen fully mature trees decimated and even killed with all fronds burned off. We have just finished our second winter in a row with temps this low and mature trees still have most of the canopy brown and I am getting concern that caliper growth (trunk growth) is going to very hampered.

If you want to try this tree in zone 8b, try to find as sheltered of a location as possible either near a building or other trees, or in the best case, bodies of water. Unfortunately with this palm's height, it is difficult to have protection as it quickly gets taller than most houses. After these last two winters and witnessing multiple large, mature specimens die, I am starting to realize that in the long term it is probably not worth planting this palm if you don't live near the beaches or some body of water.

However, I have noticed one promising trend. In some plantings I have noticed the closely related and very similar California Fan palm (Washingtonia filifera) mixed in (or possibly breeded together) with Washingtonia robusta (Mexican fan palm). There is one such planting out in front of the Northwest Florida Regional Airport. One of the fan palms has a much thicker trunk than the rest as well as larger scale leaves and is probably a filifera or hybrid between the two. After these last two winters, this tree has shown virtually no damage while the true Mexican fan palms around it have been fried or even killed. It is possible that the California fan palm may be a good replacement as the Mexican fan palm is just not that hardy this far north.

This is how Washingtonia most-likely-robusta does in the Azores:

Some do ok, some are like this. The climate in the Azores is 50F to 80F (+10C to +27C) year round and it never goes below 46F (+7C) or above 85F (+29C), which includes winter nights and summer days.

Best palm for the Azores is a CIDP and some cooler tropical varieties that don't need too much heat.

We bought a house last fall because of the backyard, it is gorgeous! There were 8 palms in the yard, we removed 2 small ones because ther...Read Moree were so many in the small area. The oldest Fan Palm is 8 years old and stands 50 feet. The palms are beautiful, they make the backyard look tropical and lush, we loved the way they look!

Spring came and the living nightmare began.

It has become a full time job to clean the beds, the pool filters and skimmers at least twice a day, vacuum the walkways, cracks and outdoor furniture and pull seeds from every surface imaginable. I totally agree with GardenSox - these palms are horrible! The casings from literally millions of seeds on one 'flower' finally stops snowing and the pea size seeds themselves start dropping. Each tree appears to have 20-40 'flower stalks', each one occupied by literally millions of seeds. It started in early June and still continues. If they do this next year we will have to cut the trees down!

Palm trees should NEVER be planted near a pool unless you have full time gardening and pool maintenance service available.

Can someone help me? I planted two of these palms about a week ago by my pool in Houston, TX.... They now look dead and the leaves are ha...Read Morenging down instead of up. What could I have done wrong?? Are they in shock after being transported?? Are they already dead?? So frustrating to spend this money, and I even bought Palm Feed. What do I do???

This palm, along with the hybrid variety (Mexican/California Fan mix) are very common in St. George, Utah,
the climate here is ve...Read Morery similar to Las Vegas, NV, as both cities are in the Mojave Desert. The only real negative is since we're slightly higher in elevation (2700-2800 ft.), there tends to be more nights at or below freezing in December and January causing the fronds to severely brown which makes for a couple short months of unsightly palms and also requiring trimming/cleaning in the spring that can be costly if using a commercial contractor.
However, the climate is obviously warm enough that people rarely wrap them with burlap as it's really not needed here, but I'd recommend wrapping the young and newly planted ones just incase.

Most Mexican Fan palms in the St. George area are probably 25 to 40 years old, so the tallest (about 40-60 ft) were most likely transported in quite tall from SoCal, so it's not clear whether they will naturally reach heights like they do down there or even in nearby Las Vegas.
Last winter we experienced a record cold spell where two nights dropped to 12 degrees F., to my surprise, the area lost very few palms, the ones that didn't make it were younger, unprotected specimens in the higher, outlying areas of the valley. So, that proves these palms are indeed cold hardier than given credit for!

I agree with GardenSox. I have a friend who has one of these palms in her yard. Last spring she planted a new lawn, and now there are h...Read Moreundreds of palm seedlings sprouting up all throughout the yard. I've also seen them in the neighbor's yard. The seeds are also spread by birds.

My next door neighbor has a mature Washingtonia robusta right next to our property line. It is probably 50 or 60 feet tall at this point...Read More and I suppose it looks just fine now that they've cleaned up the rat-infested fronds that "adorn" this terrible tree.

Am I being harsh? You tell me - the Washingtonia robusta drops thousands of seedlings which sprout everywhere. They grow in cracks in the sidewalk, they grow in your gutters if you haven't cleaned them out recently, they grow in your flower beds, they grow in your lawn, they grow in gravel pathways . . . they grow and grow. I spend about 30 minutes each weekend, almost all year round, plucking out seedlings just to stay on top of the chore.

When it gets windy out, the fronds (which have sharp spikes on them) tend to drop with a vengeance. Imagine waking up at 2:30 a.m. because a 6 foot frond fell from 60 feet above onto the roof of your house. It is unpleasant; trust me.

It seems like there must be better palms out there to choose from. Do your neighbors a solid and avoid this one like the plague it is.

This palm is common in Southwest Florida, becoming increasingly so as you head north up the coast. Does well here but lightning, humidi...Read Morety and hurricanes keep it from reaching the heights that they do out west.

My strong personal preference is that this palm looks best when the boots and petticoat are removed. Most are not maintained this way in Southwest Florida.

About ten years ago, my husband and I purchased a goodly-sized double Washingtonia palm and had it placed by heavy equipment into our bac...Read Morek yard. It was a splurge purchase, but having just moved to Florida, I wanted palm trees. We had one (different variety) in the front yard, but wanted one in the back yard, as well. I learned that palm trees are very slow-growing and Washingtonia are one of the fastest growing palms, so that is how we decided to go with this variety!

Not being botany-savvy, I don't know if one palm grew into two trunks or two palms grew so close together that their root balls became one.

All was well until this year, when it appeared that one of the trunks on the double palm had died - the other side is very healthy and has new foliage. We were hoping to see signs of life during the spring, however, the side we suspected was dead shows no new growth and feels mushy to firm pressure, so I guess the one side truly is dead. :-(

How do we go about cutting that side off without harming it's 'Siamese twin?' My husband thinks we should saw-off the dead portion as close to the root as we can without disturbing the root. We love the palm and want to get rid of the dead portion of the double-palm without harming the live side. Any suggestions/help would be greatly appreciated.

We'll share our experience with the palm when we learn what to do and try it!

Thank you so much, in advance, to anyone who can guide us as how to get rid of the dead side without harming the live side.

I am in a Zone 8A (Orangeburg county, SC) perhaps ~50 miles south of the old USDA Zone 7B border.

I planted a 8 ft. tall W...Read Moreashingtonia Robusta in August 2009 in a sheltered sunny location on a south side of my house about 2-3 ft. from the wall. It had beautiful foliage, which browned and broke during the winter in December and January. I wrapped it with burlap a lot during the most cold weather for a couple weeks in January. Some time in January there was a unusual snow storm with LOTS of snow which lasted for 2 days although temperatures stayed normal. I was told it will be growing like crazy in May and it did grow a little bit during May (today is 27th of May). It grew a green stem of about 12" inches and another stem of about 5" inches both holding the browned foliage. That is all. Nothing else has come out of it and currently I think it kind f stopped growing, I think.

What is wrong with it? I live in a small town surrounded by forests. Perhaps all the forests and trees cool down and reduce the climate from 8A to a lesser one?

In fact I saw a couple very tall Washingtonias in Columbia, SC area and they were all or partially browned, but seemed doing quite well. One of them I suspect could be a Filifera. It's growing next to some radio station on East side of Columbia.

Also I find European Fan Palm (Chamaerops) not hardy enough for zone 8A since it gets most of the foliage brown during winter where I live, although it does not die and soon recovers some of the foliage. Could this be caused by a rural climate away from cities and from lakes?

Also, I got another 2 robustas which were beautifully green at the nursery, who tied their tops upwith rope in March, yet once planted in my place the foliage became yellow and then brown a lot. Apparently while in the nursery they probably got some freezing weather in March this year 2010 which seems to have damaged the foliage.

So my experience with Washingtonia so far is so-so.

UPDATE: January 2012: Got 3 of them in my garden one last spring and two a couple years ago. Overwintered fine, with a little help from anti-fungal spray. The fronds all browned, but grew back during the year and the fronds were still growing at the end of December 2011! The last winter 2010/11 was so-so with 3 snowy days, but the temps did not go below 16-17F. This winter 2011-12 so far the coldest night was just down to 28F but the next 2 nights were forecasted to become 22-25F. Very mild winter for a zone 8A! Looks like we are getting 8B/9A zone climate here, which is great news for growing palm trees.

One of the Washingtonia robustas is growing faster and larger than the other one. Not sure why. Perhaps because the slower growing one was planted slightly too high by the "professional" nursery specialist.

2014 winter update: Washingtonia robusta will not survive in zone 8A long term. Regarding zone 8B, probably not as well. Cold winter will kill it, especially when it's tall. Get a hybrid or a W. filifera.

Regarding Washingtonia robusta germination, they usually germinate around 80-90% (unless you buy your seeds from Banana Tree Inc. who's seeds are so old that their germination rate is between 0% and 20%).

WARNING: There are multiple nurseries in South Carolina that sell Washingtonia robustas as hardy to Columbia and even Greenville or Charlotte area. They are FRAUD. Those nurseries do not even know what a W. filibusta or a W. filifera is let alone know or care or want how to plant them correctly. DO NOT buy W. robustas in SC unless you live on the extreme southern coast of SC and unless you have time and money to waste. Your best chance of a Washingtonia surviving in SC is to find a Washingtonia robusta x filifera (filibusta) hybrid or a Washingtonia filifera. Those (in a size of 2+ feet of clear trunk may survive down to 10-12F). This cold 2014 winter my Washingtonia filibusta of just 1+ foot of clear trunk survived in a pot and is now slowly recovering and growing again. It will go into the ground this spring. Will keep you informed.

REMEMBER: Natural or unnatural (chemtrailed, geoengineered) weather will kill your Wash. robusta in zone 8A in long term.

P.S. If you don't know how to identify those three Washingtonia family members, contact me, and I will be able to help you purchase the right palm for your area and to identify the right variety of Washingtonia for you. I'm now a registered backyard hobby nursery.

Specimens in town seem to get only about 8 feet or so, and tend to be more shrub-shaped than tall. We get about 30-40 freezes a year, but they seldom last more than about 2 to 4 hours. The freezes cause the tips of the fans to turn brown, but by mid-May those fans become the lower fans and can be cut off, so the tree looks marvelous by summer. My palm doesn't get sun before noon, so it tolerates going from cool to 100-degree furnace-hot each day in the summer. In three years, it has grown to about 7 feet tall and is almost as wide. Give this palm plenty of room on the sides. I love the little white strings it gets along the edges of the fingers on the fans! I have a drip irrigation on it -- literally just a little drip for about 10 minutes a day. In the record drought we had this year, this palm thrived. Hope it doesn't get as tall as some contributors have indicated, but will enjoy it, even so.

Contrary to what Palm Bob has written Mexican Fans do grow very tall in Miami and the rest of Florida (I have seen some SoCal sized Robus...Read Moretas in Sarasota and all along the west coast of Florida). I will say the rarity of seeing these guys grow so tall in South Florida is because of a few things: 1) The aforementioned storms, we get lots of rain with very strong winds and lightening. It is not uncommon to see Robusta's busted. 2) It seems they were not planted very often a long time ago. This has changed as they are planted all along I95, near most schools and malls. Way back when people mostly seemed to want to plant Jamaican tall Coconut Palms, but the Coconut Palms have not been planted like they were due to leathal yellowing. 3) There are so many palm choices here. In SoCal it is common to just see the Mexican Fans and Date palms and not much else (Queens and California fans). 4) Not too many areas of South Florida are the 80 + years old to have fully matured Mexican Fans. Most places here are very young, where clear cut when settled and again more common south florida palms (Sabal, Florida Royal, Cuban Royal, King ,etc.) are grown. I submitted a larger Mexican fan palm example from here in Miami. I will be taking more. The ones I submitted happen to be on the grounds of one of the oldest historical places here in Miami, Hialeah Park (horse racing track built in the 20's or 30's). The Royal Palms in the park are actually taller. Other places to see fairly tall Mexican fans are in the older neighborhoods of Miami Beach, Star Island, Palm Island, Coconut Grove (South Bayshore Drive south of Monty's), Miami Seaquarium parking lot, Oakland Park Blvd. (especially intersection of Inverary) and older Coral Gables neighborhoods. But for those that live in South Florida, one of the coolest Palm locations (other than the beaches) has to be Hollywood Blvd. from the Beach to about 2 miles east of A1A. Huge Royals and some Mexican Fans thrown in. I will submit some pics of those here before I move, coincidentally enough, to LA.
