who here has the most northern exotic palm collection ?


trioderob

Recommended Posts

so there are well know collectors and growers in southern Cali and Florida - but what about as we head north ?

now I am not talking about a guy in new york with one ultra cold tolerant species - i talking about a nice collection with dypisis, jub, bizzie, copernicia etc..........

I am also not talking about indoor collections

I am talking the farthest north palm nut. I am talking the killer micro climate to allow it. I am talking the money grit and determination to pull it off.

could that be you ?

they say a photo is worth one million words

this is what I am talking about the start of the tundra line for exotic palm collections in the untied states - the place where the last dypsis lives and the last bizzie buds.

if I am guessing it would have  be one of you in Oregon or north Europe.

central US is out - east coast gets freezes so its probably out too.

Europe seems prime - warm water currents

We had a palm talker in Norway 100 miles south of the Arctic Circle. Northern Ireland is far up there, too.

Channel Islands or Amsterdam City climate would be my guess for europe. I will move to the countryside next year to start my first real garden but without planting any palms. I`m even moving from 7a to 6b. :)

Personally i do not like most of the frost hardy palms. Bringing them indoors over the winter is a must over here. I had some Dypsis and a Bizzie outside this year from April until the beginning of October. Brought them in after the first freezes over night.

Dick's garden is a few miles away.  It's a great cold hardy garden, but I'm not sure I'd call it an "exotic" garden - e.g. I don't think there are any dypsis, bizzie, copernicia, etc.  On the main it is super bullet-proof stuff that would survive well north of here.  Guess it all depends on your definition.

Jim's would fit my definition too.  But - looking at that other thread with royals at like 40 degrees N in Spain etc., you'd think there's be possibilities even further north there.

Dick's Garden first came to mind reading the topic. Dick was a pioneer establishing a collection in a temperate climate. These many years later, we now know which palms are truly cold hardy because of Dick. I'm certain he tried many species that could not make it. Coming from Florida, he had to do a lot of experimentation because no body knew.

I agree, Jim defintely has a more exotic collection. Let's not forget Darold Petty, he also has a very nice collection of exotics.

Yeah it depends on your definition, because for like a FL Panhandle 8b, you could go to the full length of planning a tropical palm garden to make it really bullet proof, including being able to withstand freezes approaching 10 degrees, which has happened more than once in the last 30-40 years or so- such that all it would boil down to is sabals, windmill, butia, saw palmetto, Chamaerops, needle, etc... Basically things that our friends in places like the mid-U.S. are growing. 

And then on on the other side of the coin, you would be a little more zone pushing with some 9a or even 9b palms because something like 65-70% of the time, we have more 9a type winters.

I nominate the garden of Dr. John Rossi in, a bit south for this thread, Hastings FL. This absolutely doesn't first come to mind when thinking of "northern" although for a place that regularly drops to the 20's (9a) it's impressive to see Bottle's (interestingly, heated by a car engine during freezes!), Royal's, Archie's, Pritchardia's, Dypsis', Trithinax,  Cocos (juvenile), it just goes on...

My garden is  37.73940 degrees latitude.  I have approximately 25 or 30 species in the ground, I have not done an inventory for a long time, perhaps I should !!  :) 

 Dick's garden at 37.93019 is slightly higher latitude than mine, but we have very different microclimates.

Okay... I'm going to troll here... I would say the whole of the UK would take this prize. Apparently what is not just surviving but thriving there according to some (actually a) member on here is nothing short of amazing, we're talking Royals, pretty much 'anything short of coconuts'.

No, in all seriousness the UK does shine at 53N with some great zone pushing compared to continental climates like the US.

To switch to the other hemisphere, here in southern New Zealand the following can be found at 43S although the botanic gardens lacks some less-exotic palms like Archontophoenix Cunninghamiana and Syagrus Romanzoffiana that actually would grow okay there.

Not a chance that Roystonea grows anywhere in the UK. I’d love to see photos. 
 

in the Southern Hemisphere @Tassie_Troy1971 would have to be a contender.

I nominate Troy Donovan  Tassie_Troy1971.  His garden in the suburbs of Hobart is at 42 degrees south latitude.  His garden has many palms and they are ALL very well grown.  His garden has even been featured on Australian television.  :greenthumb:

Hey now! Seattle, WA here at 47 degrees N. I'll give those Europeans a run for their money. I'm located just a stone's throw from the sea and sit comfortably in a USDA zone 9a microclimate.

I've got quite a lot of fun stuff in ground. Strictly talking palms, I'm growing Jubaea, Butia, Trithrinax campestris and Brasiliensis, Butiagrus, Allagoptera arenaria, Arenga engleri, Rhapsis excelsa, Brahea edulis, Chameadorea microspadix and radicalis and Parajubaea TVT.

I've also got plenty of other exotics and a commendable container ranch.

Gah! You win. Although I'm willing to call it close, I'm at 47.5 degrees and they're at 49.5. That puts it at around 140 miles north of me. Closest thing I can counter with is Tofino, British Columbia, Canada. Similar microclimate to mine with a lot of tropicals in town.

Very cool!  Yeah, this isn't even to speak of tropicals planted across the UK, above 50 degrees...London is in the south and already 51.5...

I understood that it was only possible to grow things like Phoenix Canariensis and Washingtonia in the southwestern part of Oregon near the border with California around 42.03.

That is comparable with Vigo in Galicie Western Spain(zone 10A). 

It is possible to grow Phoenix and Washingtonia palms on the English southcoast in places like Portsmouth which 50.57.

There are some pretty large CIDP's and Washies at 51N in London and across southern England in general. One of the big Filifera's over here is at 52N I think. 

If I'm not mistaken, there are now also flowering CIDP's at 54N along the east coast, near Yorkshire. I'm not sure if they have actually set seed though. They don't get much summer heat at all there, unlike London and southern England.

This is one of the CIDP's in Scarborough at 54N. That may well be the furthest north flowering/established CIDP in the world? Or furthest from the equator even? Surely? I wonder what it will look like 10-15 years from now...

Victoria, Canada is at 48N and is supposedly considered a 'warm-summer Mediterranean' climate, yet I can't see any long term CIDP's growing there? Or any Washingtonia? Does anyone else know of any maybe? I know they have lots of Trachycarpus, but I can't see CIDP's or Washies. I still don't see how Victoria can be 'warm-summer Med' if they are a bit colder year-round than London and also experience more annual rainfall. I would hedge a bet that the London summers have been a LOT drier than Victoria's as well in recent years. 

I also thought they would have some CIDP's growing somewhere in Scandinavia, in the warmer regions at least, but I can't seem to find any at all. I'm guessing their winter lows are just a step too far for CIDP even. The same goes for Paris, France which is also at 48N. I saw quite a few CIDP's there but they were all situated in planting boxes that get wheeled inside each winter. I know Paris saw 8F (-13C) back in 2018 though saying that.

I think the lowest central London has seen since the year 2000 is about 22F (-5C). But central and eastern London have been frost-free for the past 2 winters. The lowest in east London last winter was 35F. I think London is starting to get an edge on Tresco now even due to obvious climate change here and since it has much hotter summers than Tresco, allowing quicker growth. The past 3 consecutive summers have reached 100F in London now and have been very dry, akin to a Med climate. I doubt Tresco has gone above 80F during that time. 

I was in London (51N) for a couple of hours last week and spotted at least several hundred CIDP's. I mean they are absolutely everywhere now. Almost every street has one. Often several. Most are recent plantings, but a lot of them were big specimens carrying flower inflorescence. Quite a few of them I would say are over 30 foot in height now. One of the pictures below shows 4 biggish CIDP's in one frame, including one down the road in the distance. At 51N, surely London is the furthest place from the equator with a large palm collection...? Correct me if wrong...

Nice photo's. I think in Europe the northern limit for growing Canariensis/Washingtonia unprotected long term is the English southcoast and London. Perhaps the southwestern tip of Irland is another place. I am not sure Canariensis and Washingtonia survives unprotected long term farther north in England to be honest. Engeland has the advantage over countries like the Netherlands and Belgium that it is not directly connected to the continent.  I think on the continent you have to go to places in Brittany like Brest(at about 48 N) before you can grow them.

I think globally the northern limit for growing CIDP's is 54N on the east coast of England, like the one I uploaded from Scarborough in my first post in this thread. There could however be a few decent sized specimens in western Scotland at 56-57N, but I'm not sure. I've heard it mentioned for years though. The west coast of Scotland is certainly mild enough in winter due to the jet stream, but they get hardly any summer heat, so probably don't grow well. When London hit 100F last Friday, the west coast of Scotland was like 60-65F. So world's apart climate-wise. In the southern hemisphere, I think the furthest south CIDP is at 46S, give or take a degree or two of latitude. 

Anywhere further north than London at 51N, I would not trust Washingtonia Robusta. Even in London they do not seem to grow as well as the Filifera does, at least in the long term (my observations). But there are still lots of big Robusta's taking off en-route to becoming 'skydusters'. But I think Filifera are just better at dealing with the winter cold, which helps them this far north. So I think Filifera and hybrids could maybe make it at 53N here, but not so much Robusta's. You won't really see a decent sized Robusta outside of London or the south coast. Although saying that, here are two Robusta's (and a Phoenix Theophrasti) at 52N, as well as a Filifera, so who really knows what the zone pushing limit is anymore over here... 

PJ2014_1.jpg.1a77a16826dc8561a34455409c9217de.jpg

The image is poor quality, and from 2016, but that is one serious 'skyduster' for latitude 52N...
