I realise this is somewhat subjective as hardiness will vary with other climatic variables, but hopefully this will give some idea and complement Wal's and Chris's threads.

As with Wal's poll, I have included ten species, they are either similar or generally thought of as being amongst the most cold tolerant or from high altitude.

Other suggestions welcomed.

Heres is a list of Dypsis from high altitudes, information taken from P.O.M. may be of use, i think someone else posted it a long time ago.

Palm, Altitude and location on Island North/South/central and number of locations noted in P.O.M.

D. Onilahensis 750-2400m (from south to north 19 loc)

D. heteromorpha 1300-2200m    (Nth 4 locations)

D. Pumila 1500-2100m                (Nth 1)

D. ankaizinensis 1400-2000m     (Nth 1)

D. decipiens 1400-2000m            (central 5)

D.acuminum 700-1900m              (Nth 2)

D. catatiana 450-1900m              (Nth to Sth 20)

D. coursii 900-1850                      (Nth 4)                        

D. curtisii 1500-1800m                 (Nth 1)

D. andrianatonga 700-1800m      (Nth 6)

D. tsaratananensis 1000-1700m  (Nth 1)

D. bonsai 1000-1700m                 (Nth 2)

D. oreophila-500-1700m               (Nth 4)

D. ambrositrae 1300-1500m         (central 2)

D. montana 1100-1500m              (Nth 2)

D. baronii 850-1470m                   (Nth to Mid east 13)

D. orpedionis 1100-1450m           (central 2)

D. alborfarisona= unknown

D. sp fine leaf(fake ambrositrae)=unknown

There are a few other odd ones that could fit in such as D.pinnatifronds to 1000m            (Nth to South 27)

D. nodifera 5-1440m                    (Nth to south 28)

In particular there are also some Dypsis that may have cold tolerence from the far south at lower altitudes an example of this is D. decaryi that has some cold tolerence but is only found to  600m.

Then theres also the case of not knowing what altitude the seed came from with some palms altitude habitat varying greatly, and you could asume most seed comes from lower altitudes as why would you go to the top of the mountain to get something that can be found at the bottom of the mountain.

So perhaps we are not growing the most cold tolerent forms of some palms.

This is just a possible scenerio I will use D. Baronii, but im not saying this is the case just a possibilty for any palm.

D. baronii perhaps the first seed that was collected was from a lower altitude 850m, taken back to the west and grown in a garden, being a fairly quick to grow and seed the palm sets seed, seedlings grown and sold, starts a generation of palms that set seed and the amount of seed needed to be imported from madagascar is lower as the seed can be obtained without going to madagascar.

So we end up with most plants being from the same area a low altitude area.

Years latter in high altitudes D. baronii is found but looks much the same there is no need to bring back to much seed as seed is available easily already in the west.

We all grow the original D. baronii from the lower altitudes and think the cold tolerence is( A) when really the D. baronii from higher altitudes such as 1470m could be much more cold tolerent and handle up to (T).

In reality I think it is more likely the strains of palms we are growing are from a lower altitude than from the highest possible altitude.

And one can asume the higher altitude plants could be more cold tolerent.

I don't know much about some of those palms, and all I have is seedlings.. .but I can tell you in the seedlng category, even Dypsis decipiens, the 'king' of cold here in So Cal, is a wimp compared to D saintluceii.  D albofarinosa, ambositrae and baronii are certainly not the most cold tolerant as all those are dead after my latest freeze.  D lutescens in mostly dead, and D carlsmithii is partly dead... but none of my 4 D saintluceis were even burned.  Dypsis decipiens was burned badly, but will live.

Decipiens, by far.

Nothing else even comes close.  None suffered a scratch from the great freeze, and people tell me they've taken down to 17 F (-7.4 C?) no problemo amigo . . . .

Even though seedling cold tolerence and mature palm cold tolerence could be two different things, your observations of D. saintluceii are still intersting i suspected D. saintluceii had a degree of cold tolerence as even though it is from a very low altitude it is found in the far south of the Island not far from D. decaryi, it also grows in sand, so it must be a pretty tuff palm, I suspect this area could have coldish winds also? comming off the southern ocean where the water only gets colder as you go south.

(although a negative for D. saintluceii in a cool climate could be it's growth rate, I have found it to be a bit slow growth wise even here in the subtropics)

I have a theory that if a palm sp can handle tuff/extreme conditions such as dry conditions or excessive water then it's chances of handling cold maybee increased, offcourse it's not a rule and deffinetly not true in some cases, but for example if the palm was from a not too tropical area or moderate altitude and can also handle extreme moisture conditions, it could be worth a go in a cooler climate.

It's strange but some palms from very wet areas also handle very dry conditions (dont always look great).

and a even a degree of cold, as though there growing extreme makes them tougher, palms that come to mind Phoneix roebelenii, Chamadorea cataractrum, Ravenea rivularis.

D. saintluceii is one dypsis i suspected another that i would be interested if anyone had tryed to grow in a less than ideal climate cold wise (not frost) is D. rivularis anybody tryed this???

I say this because D. rivularis obviously grows in a very wet situation, it's altitude is moderate at 130-300m but I have also found it to be a really good grower even under fairly dry conditions and all year round.

I think when your talking about cold hardiness there can also be two meanings.

Cold hardiness in very low temps frost.

Cold hardiness as in is it hardy to cold, will it grow without tropical warmth?

Good point Sebastian,    I would discriminate between these two as cold tolerance and cool tolerance.  Here in Melbourne as you know,   plams must survive through a long cool damp winter.     The best looking palms in Melbourne are,  CIDP, Jubaea,  Washys and Howeas,  both types.   There are many Howeas here which would be  30-50 years old.   Generally they are very very good looking.

But Howeas are slow.   IMO theres not anything wrong with slow palms,  which are actually a good thing among other faster growing ones.  Its just that its imperative that they are protected from wind,  so the leaves are not damaged and that enables them to hold sufficient leaves to be viable ...... otherwise a trashy looking dypsis is just as bad as a trashy syagrus rom.  Only my opinion !

The trials have to be done,  but I think we will struggle to find many Dypsis that are worth growing in this climate....... that is,  that will look good in the landscape.

D. saintluceii may be worth a try.

Do you mean any other dypsis than are currently grown there, or Dypsis in whole.

I would of thought some would be tough enough to cold and wind like.

D. decipeins-(pretty tuff leafs, and 3 leafs per year isn't a bad growth rate for this one)

D. baronii- small enough to shelter from wind.

D. Onilahensis

A lot of those high altitude Dypsis are fairly small also.

Maybee im just being optomistic cause im sitting up here in Q.L.D melting : )

I have the following growing here

1. Fastest  D. baronii  [PFB 2003]  4 leaves per year

2. Next fastest D decipiens.   3 leaves per year on average, [ emerge 2 spears at once from each stem.

3. D.  decaryi..... grows quite well and there are some large plants in the landscape near here  

4. Next fastest,  D. albofarinosa........ [ PFB 2005]  2 leaves per year.  Survives,  but I dont think its viable long term

Tried and failed:  

D. lutescens.... survives,  but is a basket case.

D. lastelliana...... shrivel and die !  [ all seedlings]

D. leptocheilos...... karked it in short order.

[ all seedlings]

Thats really why I wanted to know about the fastest cool tolerant Dypsis,  and it seems we have identified about 2 others.

3. D.  decaryi..... grows quite well and there are some large plants in the landscape near here

Good to hear, That could possibly open up the possibilty of growing D. decaryi hybrids in the future, PFB have in the past had D.decaryi X sp fine leaf (formely known as ambrositrae) they even had one, over a year back that had about two foot of trunk, nice greenish,chalky trunk, you would imagine that would be as cool hardy or more than a standard decaryi.

There's also a chance decaryi could hybridize with onilahensis or baronii???

Thats really why I wanted to know about the fastest cool tolerant Dypsis,  and it seems we have identified about 2 others

What were you thinking the two others are?

D. onilahensis

D. sp fine leaf

Perhaps what has been sold in Q.L.D as "wild seed ambrositrae" could be worth a try also, it seems to be a form of baronii but looks a little different.

Someone seems to think D. heteromorpha could be pretty cold hardy on the graph, Id expect it to be true with a high min altitude and a very high max altitude, P.O.M describes it as related to baronii and onilahensis and possibly a variant of the former.

Finding one could be the hard part though.

Hi Sebastian,

I have found that some of the species that come from the bottom of Madagascar are quite cold tolerant, when well looked after.

Here is a few that I think would be worth a try not all are from the bottom,

D.occidentalis,

D. scottiana,

D.malcomberi

D. linearis

D.humbertii

D.mcdonaldiana,

The high land red neck (hovomandrinia) local name.

A few of the forms of D. madagascariensis

And if you could find this one D.brevicaulis.

There probably will be others that could show some cold tolerance but I’m sure with forums like this we will soon find out which ones work and which ones need a little more heat.

All the best   :)

I can't comment on which is the most cold hardy, we only get down to 2C here, but my fastest is D. baronii.  The only Dypsis I've had die from cold is D. scottiana.  I'm growing albofarinosa, baronii, carlsmithii, nauseosa, ovobontsira, pembana, lutescens (not the best grower), decipiens, onilahensis, a 'white' Dypsis and one called canaliculata.  Decipiens, baronii, onilahensis and albofarinosa are the best growers of these.

From the point of view of most growers here in Spain 'decipiens' wins hands down. I struggle with Bismarckia and Dypsis decaryi here in Valencia  although they thrive further south, but decipiens comes through unscathed. I still believe that unless you get hold of a very a rare larger plant they would stand no chance in the UK as there just is'nt enough heat.

Would you label these photos?  I think only the decaryi is noted, and you've said here that the last is saintlucei.  Again, very intersting.

Ok, the first one is Dypsis decipiens- was shocked by that one (since that photo, most of plant turned totally brown with only a trace of green in middle leaf)

The second one is a Dypsis ambositrae that I had for 7 years now- from a 1 leaf seedling... sigh.  Another even larger one looks similalr, but harder to photograph

The third one is a D baronii that used to have leaves that went well over my head- very protected corner of the yard, too... ouch.  At least it's still alive I think.. the one out front is totally dead

The 4th is a triangle, of course.  No surprise there... just took a while to do the color change.  Still alive, I think, though... spike at least has some firmness near the bottom

Last one of course is the little Dypsis saintlucei out front- surrounded by fried Chamaedoreas, Caryotas, Raveneas and other Dypsis... and happy as can be.

Psalmophila ?( mines the the bannana yellow crownshafted clumper 7years,D. Boronii 12 years .No damage from cold this year on any of these! D. Decipians is cold hardy in my yard but slow from lack of summer heat,I've planted around ten over the years have about 3 still growing ,thats not to good .Teddybear got extensive damage,usually does pretty good ,lasteliana (mine has trunk)looks like chambeyronias,D.Madagascarensis always looks bad after winter no worse this year ,15 years 6 feet of trunk.Big red did better than teddy and lasty.D. Ambositrae has never done well for me not enough heat?I got D. Cabade seed 7 years ago seed matches Cabade but plants were fast and cold hardy , plants look like Cabade, did fine this winter .Ok thats all for now.

I had moderate leaf tip damage to one of my D. decipiens at 26F while my D. saintlucei a few feet away looks perfect. Both are about 18" tall. Seven year old D. Decipiens was not damaged. Lost most of the leaves on my five D.decaryi in the shade but all are recovering. Seven year old D. baronii lost four of its five stems.

Great and interesting list of Dypsis, my new palm obsession.

What about rare D. cookei. is it not pretty hardy?

D. saintluceii is from very low elevation like 500m or less and from humid forest to boot. So I am really surprised it made the list.... :hmm:

Posted

I have tried D.saintluciei but they always die in the middle of summer. Pembana, Cabadae, teddy bears and sp avisonii, dont seem to by bothered by below freezing temps here. Lutescens and decaryi can take very cold temperatures and only a bad frost will damage them, but only cosmetic damage that is soon repaired. Dypsis sp fine leaf (fakey) gets spotty and starts to suffer bronzing on the leaves after a couple of nights below 2c. I don't think they are particulary hardy to severe cold and definately wouldnt survive a frost, although they may do well in a cool climate situation without extremes like we get here.

Yup! I've had mine for several years. It lost its spear this winter with lows around 20 degrees for many hours but is growing very well now that the hot weather has returned! This is definitely the hardiest Dypsis as its the only one that can survive our lows.

Welcome to the Dypsis lovers club... :D

But one thing you'll sadly find, while there are way more available than there were 10-20 years ago, many are still really found in the books! No seedlings for sale and quite often the seeds are suspect of their correct origin.

D. cookei comes to mind...

Zone 10a at best after 2007 AND 2013, on SW facing hill, 1 1/2 miles from coast in Oceanside, CA. 30-98 degrees, and 45-80deg. about 95% of the time.

I do some experiments and learning in my garden with palms so you don't have to experience the pain! Look at my old threads to find various observations and tips!

Posted (edited)

I thought it was d. decipiens, but now i am a little confused... :blink:

I have 3 decipiens, thriving (two new leaves after 2 months) in the ground.

Rafael - D saintluceii was mention by Geoff as being hardy for him.

Dave I'm still a beginner when it come to more tropical palms but I'm learning, and really appreciate this posting! :D

D. decipiens is still the hardiest for the west coast and for you too Rafael since your climate is probably like part of CA. I don't have one yet, but if I did I would have to protect it from severe winter cold spells up here at 47N. The weather in my part of PNW is crazy, last Decembers low was 12F (-11C) no snow. ( the coldest in 10 years) January 2010 low was 30F and March and April 28F. Here the daytime highs in winter are only in the 40-50's. We do get some tropical rain in winter a few times when the low's & high go up around 60F. But only last a few days. The most rain we have gone through in winter has been 90 day straight. We are famouse for are cloudy days.

I live 150 miles from the largest temperate rain forest in the US. See picture below, But I'm lucky I live in a rain shadow and get about as much rain per year as Miami. 60" mostly from Late October to April. Summer are cool but heat waves go into the 90's and even low 100F like last years 40C. Crazy weather here.

I have tried D.saintluciei but they always die in the middle of summer. Pembana, Cabadae, teddy bears and sp avisonii, dont seem to by bothered by below freezing temps here. Lutescens and decaryi can take very cold temperatures and only a bad frost will damage them, but only cosmetic damage that is soon repaired. Dypsis sp fine leaf (fakey) gets spotty and starts to suffer bronzing on the leaves after a couple of nights below 2c. I don't think they are particulary hardy to severe cold and definately wouldnt survive a frost, although they may do well in a cool climate situation without extremes like we get here.

I'm surprised D saintelucei don't do very well for you Peachy. I find they chug along all year around without any trouble. They don't like being too wet and humid like in my tunnel house, which is weird when you see where they come from. Maybe it's my sandy soil vs your clay as they come from a sandy habitat.

I agree with you on D sp fineleaf (which is now D plumosa). Bill Beattie thinks they come from low elevation in NW Madagascar (similar lat to Darwin) not far from where D madagascariensis is found, which is really quite tropical. I think it's cool tolerance is a fluke as it grows well in NZ, but I don't think it is frost tolerant. It's mix up with D ambositrae has meant that it's been grown in some really unsuitably cold environments.
