Hi everyone,

This is my first post here on palmtalk. My favorite palm is b. Alfredii. This is a report dedicated on how the B. Alfredii reacts to the cool climate of Northern Europe.

I live in Rotterdam, Netherlands which is hardiness zone 8 in Europe. The average anual extreme minimum here is -10 Celsius (14 Fahrenheit) for the last 5 winters.

I bought the Alfredii as a seedling. The plants have produced 2 leaves this summer.

I have 4 plants in total.

The first picture is May 2022 and the second picture is august 2022. Next year I will give an update about the plant. This year I will keep them in their pots and keep them indoors if temperature drops to freezing. 

Next year I will put them in full ground.

Interesting to see if you can keep it warm on your freeze events

I think once they hit trunking size hardiness increases, but exposure to a hard frost killed my 3 gallon size. Maybe slightly bigger than yours. I would just protect them all winter when in ground.

Good luck, but I give it zero chance of surviving it's first winter outside without some major protection.  Around -4C will kill some/ most adult alfrediis.  Seedlings would suffer around -1C, I'd guess.  I think you'd have difficulty with jubaea, but at least it might stand a chance in your climate.  Although jubaea is painfully slow, they are very attractive.  Parajubaea torallyi is similar looking to B alfredii, but has more cold and cool tolerance, which is what you need.

Thanks For the reply, I agree with you on the fact that I have my doubts. The first few years I will definitely protect them on the hardest nights with Christmas lights and wind protection. I think the odds are low but I really like to experiment and see how big I can get this tree and how cold tolerant it can be when it gets bigger. The seller told me that these specific plants currently were lab tested to withstand-3 Celsius or 27 Fahrenheit.

Thanks for the info. 3 gallons is still small I think if the roots system is exposed via the thin layer of the container that seperates it from the freezing air.

I could try one here since I have 3, cold isn't really a concern for me it's can this palm survive long cool winters max between 9-10c and average low of 5c. Would the palm slowly die or would it just go dormant for the winter and start regrowing when the temperatures warm like syagrus? I've also heard frost is more damaging to this palm than cold. I'm in 9b

Interesting to hear. Winters here are very mild for the northern position of my country (52 degrees).

However I would say the the biggest part of winter here is cool and not freezing. That is also the main reason I want to give this experiment a shot.

The point you highlight about frost is what has me concerned. It sometimes gets real ugly in terms of freezing but this does not last very long(Max like 5 days). After that it can be followed by weeks of cool weather about +5 +10 degrees celcius in the middle of January.

Is that 5 days of frost in a row or below freezing for 5 days without going above freezing? Always goes above freezing here after a frost. Coldest night of the year will range from 0c to -3c here. I was thinking of trying one unprotected but it's more the cool weather I'm concerned about because if I place it under canopy it will likely only see between 1c to -1c on an average winter and it would reduce the frost. Would be helpful if anyone knew the coolest place these can grow in to see if they would even stand a chance. My latitude is 51n

I think there are some in San Francisco while their winters are quite a bit warmer if they can be grown in san Franciscos cooler summer climate than London's that is good news because I thought this palm needs lots of heat so against a brick wall it might grow nicely in summer. We are not going through a heatwave currently just around average summer weather and San Francisco is significantly cooler. Top is San Francisco bottom is London, the night temperatures have also been warmer than the forecast every single day here.

I had 2 that died after dips below 25F. 
 

Good luck!

Seedling or mature palm? Were they under canopy or exposed?

On a “cold wave” it freezes to -7 celcius and then during the day it gets around +4 celcius if it is sunny. Maybe 1 or 2 days per year where temperature stays below freezing during the day. 
Having said that I will use winter protection in the first few years. Hopefully it will adapt once it’s gets bigger.

Hi fellow Palm enthusiast,

Winter is ending here in northwest Europe. Put all my ladies outside again. Even my cocos nucifera I put outside during the day. The rest of my palms i also leave outside at night. I am talking 1 x J. Chilensis, 2 x P dactylifera, 7 x B. Alfredii and 2 x C Parvifrons 
 

Current weather:

-Daytime 8-11 degrees Celsius and sunny.

-Nighttime 1-7 celcius.

 

can not wait for summertime

I also like this kind of palm very much. I'm not sure how cold it is. Maybe it should be potted and then tested outdoors (that might be a better idea). My other worry is that this kind of palm is not easy to buy here, so I'm worried that I can't buy it any more. At present, I only have one (slightly larger than yours). It is true how happy it is for people in non-tropical areas to find a cold-resistant palm.

Your palms are looking good!
 

Beccariophoenix is one of my favourites too (though a relatively new one to my collections) 

Will be interesting to see how you get on with yours. Having juveniles/growing from seed allows a lot more scope for experimenting and I think (at least it seems that way to me) that exposure early on gets you hardier plants (to an extent)

I am interested to follow your experience but you will need to protect very seriously with warmth and some construction around it during colder periods.  I hope you will succeed because its something special to grow these in our climate.

Btw do you know any nteresting palms in Rotterdam apart from trachies and chamaerops? I recently posted a picture of a large washingtonia in the Hague but so far i have never seen one in Rotterdam.

Good luck! I've also thought about trying it someday. Will be interesting how yours will fare. :greenthumb:

They are fine under 15c for long periods of time. My potted one is outside.

I have three in the ground and a few hundred seedlings growing in small containers here in NE Florida.  

We had a two day spell of severe cold weather at the end of December, with my recorded lows around 26F.  Due to my work schedule at the time I had no time to cover anything to protect it.  The three in the ground all suffered spear pull, many seedlings perished and many more suffered spear pull as well.  Time will tell if these survive or not.

Very nice palms you have, I have been looking for coconut looking palms that are cold hardy, best there is a mule palm but the high plateau coconut interests me. I’m a bit curious how it will look and grow when planted in the ground (if you are planting).
