Juania australis

Recommended Posts

kristof p

i've searched for years to find one of these rare palms and two weeks ago i finaly got my small Juania australis :)...i know it is not the easiest palm to grow and i hope it wil be happy in my climate without great extremes. i've seen only a few pictures of people growing them in the UK and Ireland and the ones in the Fransisco bay area (i think in the botanical garden?). are there any other places it likes to grow like for example California, New Zeeland,...?
if you have one please feel free to post a picture of it(also pictures of the palm in it's natural habitat if you've visited the RC island) and share your experiances with the plant. every help to keep it happy/alive is much apreciated :)


here's a picture of my small one, still in it's pot but wil be planted out this spring...

maybe it wil love your climate higher up in the mountains...do your nightime temperatures take a drop even during the summers? high nightimetemperares seems to be the only thing people seem to be sure it doesn't like?...ok, that and prolonged freezes with lows down to about -7°C.

is Lepidorrhachis mooreana on your list of 'palms to try'?...another temperate mountain palm that seems to be not the easiest palm in cultivation.

That's a nice looking palm Kristof. Is this a cold hardy plant?

Just found this on PACSOA, definitely not a palm for my extreme heat :(

This is an island palm, and like many palms from temperate islands, requires a very difficult to imitate set of conditions. It is apparantly not very cold tolerant (it can handle light frosts, but not much more), and also objects very strongly to night time temperatures above 15°C/60°F. It also has the annoying habit of growing seemingly happily for several years, and then suddenly dying for no apparant reason.

It has been grown successfully in San Francisco, altho the botanical gardens there lost a couple during a warm spell one summer. Surprisingly enough, it is also growing quite well in Ireland, not a place normally associated with palm growing.

It's worth a try, but if it dies, don't cry.

I call it the Suicide Palm, because they seem determined to go self-extinct.

Keep us posted!

when i bought this palm i knew it is a dificult palm but seeing the specimen in earlscliffe (Ireland) i can not resist to try it. that one in Ireland was planted there in 95 and has always been happy growing since that day. i know i dont have the same mild climate like Ireland but there it has seen a couple of icedays and lows of -7.5°C without the slightes damage! (i rarely go below -5°C most winters or above 30°C in the summer).

here's a little information about that earlscliff Juania and a picture of the same palm in 2008.

I'd love to try this one out here but I think that the high night time temps in summer might be a bit much for it. We do have success with Howea fosteriana, belmoreana and I've recently had Rhopalostyis sapida and Hedyscepe canteburyana seedlings survive for a year (their still alive and looking good). Any chance??

There is one currently flowering in Auckland. A very difficult palm to keep alive in any environment.

Here's mine, ready for planting out this spring.

Fingers crossed it will succeed like the fantastic specimen at Earlscliffe :drool:

Hi kristof,

How much did you pay for that rarety? And where did you buy it?

Thanks.

Good luck Kristof. Much of Ireland does have particularly mild winters, but the palm at Earlscliff would certainly have seen many mild freezes in it's time. The other things to bare in mind are that Ireland has very little summer heat and reasonably high year round rain.

Hi, yes the wintertemps at earlscliff are milder than mine but the rest is quite simular. i have almost exact the same amount of avarage rainfall(between 650mm and 700mm) and lows rarely exceed -5°C during winters. it is warmer up here during summer but rarely above 30°C. (on average maybe 1 or 2 days above 30°C)...

i can only hope it wil like it in my garden but i think the best way to grow this palm is to almost completely forget it..this works with a couple of other palms i find difficult to grow like Guihia's :lol:

one thing i dont entirely understand is those high nighttime temperatures because a friend of mine has one growing now for a couple of years in his greenhouse and definitely during summer this would stay quite warm at night but it seems quite happy in those conditions?

so Palm Guy, maybe it will grow in your climate :winkie:...maybe it needs lots of water during the entire year. i've read that in it's habitat it rains just everyday! not for long but it would never see real drought.

in Mediterranean Europe, the juania australis dies :(

gyuseppe,

it could be that Mediterranean climates are just to dry for them and tropical climates to warm.

humidity rarely drops under the 70%/75% range in my summers. i think airhumidity is much lower during your summers?...and i am sure rain is also kind of limitiet during your summers?(compared to what we have)

Gilles06.

i would rather not say how much i payed for that small palm, i think you can guess such rare palm is quite expensive :winkie:...i bought it at Palmhunter.be the owner of this small exotic nursery is a good friend of mine and a pioneer when it comes to growing palms in my climate. he started trying out palms in my climate around 30years ago...he bought the Juanias from dicksonia.com, 5 specimens in total and those were the last plants dicksonia.com had exceps a few larger ones. it could wel be that those were the last ones in Northern Europe so i am very glad i got one of them.

i do think that this palm wil become more available, i've seen pictures of a nursery in Chili who was growing many Juania's and i am wondering were al those Juania's wil end up? to bad you need a male and a female palm to produce seeds but there must be a few of them in cultivation that soon wil reach flowering size. (the one mentioned flowering in Auckland is very interesting and i would love to see a picture of this one :winkie: )

As Kristof says these are rare and hence not cheap. Mine was purchased from dicksonia.com and cost 150 euro. Thankfully I bought it last autumn when the GBP/euro rate was much more favourable :winkie:

Hi madgav,

good luck with your Juania, i think it will like it at your place. i think mine wil be the first one in a garden in the Benelux so i have no idea what it wil do over the years but i wil keep some protection nearby during winter...

i hope to see those Juania's that are growing in the UK/ireland in flower within a couple of years. i gues if we could get seeds of this palm it would be much more tryed in other climates and prices for this palm would be much lower...

Let's hope so Kristof :) It'll soon be time to pick a spot for it.......

I thought it was about time I had a juania since others have tried them successfully here and there seemed to be some doubts about the future supply/import of these plants. I hope they do become more readily available but I'm not sure if they will.

Gav.

Madgav,

yes, i am also not sure if it wil be much available in the future? i am still horified if i think about those nice Juania's the palm centre imported early 2008 (or was it 2007)...

they al died in the container, i think it was the authorities who did not want to release the container and they al died while waiting :unsure::rage:....

look at this sad picture of al those dead Juania's :(

In theory it should grow well in New Zealand, but so far I know of only 3 surviving past juvenile stage, and only one of those trunking and flowering... see attached picture. The photo was taken in mid winter so the palm is a bit yellow from all the rain... I wonder if it is susceptible to some fungal disease that attacks the meristem (eg Phytophtora sp.) or maybe a lack of some minerals in the soil... or maybe the temperature extremes it has to cope with outside its native habitat are just too much to handle in long term?

Good luck Kristiph & Gav. I have 2, one I have had for 4 winters & a second one which I aquired last summer which I shall plant in a few weeks time. Gav yours should do well for you as your climate is basically the same as mine. One bit of advice for both of you though is when you plant it, ensure that you also put ring or two of 6 inch Nails about 12 inches from the trunk in a circle. This is essential to allow a slow feed of iron. My first one looked a bit yellow after being in it's pot all winter this greened it up very very quickly and it has been in the rudest of health ever since.

Regards Andy.

Thanks for that Andy. I think yours was in a part shade, moist area if I remember correctly?

Haven't decided where to put mine yet :rolleyes:

Hi Andy,

thanks about the tip about the iron. any cultivation tip is very welcome when it comes to this palm...

i think i am fortunate then that the groundwater/soil here is very rich in iron :).

does anyone even knows in what kind of soil they grow in their natural habitat? this could solve maybe a couple of troubles with this palm???

Hi Kristof and Gav best of luck with your seedlings.

I kept my palm in my greenhouse through winter for the first 2 winters to bulk it up so be warned!!

If you get -7.5 C Kristof without double fleecing it will burn all the leaves off and as you know -9 C will probably kill it like Ade Shattocks poor palm.

Mine has been in the ground 3 or 4 years now but last year with -6 C for a week it burnt badly though it is making a good comeback now and is looking nice and greenish.Temps above 15 C at night will stop the palm growing stone dead and mine grows best in September and October in my garden when the temps have dropped and we only make 25 C occasionally. :unsure:

The picture I took of all the dead Juanias in Kristof's post was heart breaking to see and such a waste of a prized palm.........I believe they were not allowed to be watered while being fumigated.

Marian the trunked Juania pic you have posted looks fab a stunner. :drool: and those grove of Juania Ghar look fantastic thanks for posting.

I have just travelled 300 miles partly to see some more Juania growing outside here in the UK and will post pics and a short you-tube vid here when I get my act together though we arrived back only yesterday.

Mine before the burn.

Mine has been left out in its 'pot' virtually all winter and was only brought inside on the coldest nights. Probably not even necessary since my minimum for the winter has been -3C (27F).

Once planted out I expect to be giving it some TLC for the first few winters, even if the lows are no worse than that.

Look forward to seeing the pics Kev :drool:

Great one Kristof, i'm defitnely interested how this palm will grow in your garden. We had talked about it before, where it does growing and where not. I'm not going to try this palm species, because i do think it will died over here too (my garden). But keep me updated please :)

Marian..

I think that you are right about being suseptible to Pytopthora. My one was growing well in the ground for 4 or 5 years and then died suddenly. I had no idea back then what had caused its demise but with experience/knowledge gained since, I have no doubt that Phytopthora was the cause.

cheers..

Malcolm

I've not seen one in person much less tried to grow one. Good luck with yours Kristoff. From what I've read, this palm is perhaps the most unforgiving in cultivation with its very specific requirements.

      Hi folks...been a while...Palms seem to be doing well in south facing situation in Springfield, Northern Virginia...this Mediterranean Fan gets a burlap corral and top...just gets a string of C-9 lights around the perimeter at ground level to let a little heat rise. Got it at a local garden center. They had it in a greenhouse...had 3 leaves covered in mites...a little in ground situation, some mite killer and it exploded...I think in ground since 2014...This Brazoria seems way too far north...it suffered the winter before last but last winter was an easy one...just gets a little burlap tent in the winter, no heat...Maybe I’ll add some C-9’s this winter...will enjoy it while it lasts.This McCurtain is the slowest growing thing ever but is finally getting what appears to be a mature leaf...guess it needed several years to sink a root/trunk deep in the ground?This is my baby! In ground since 2014...planted with about a 12” trunk...now 7 feet..and has been through it all...used to be under a Heavy shade large pine tree but we had to cut that down and suddenly it was in full sun...suffered from that a bit but now seems more than happy...the only protection it gets is black frost cloth on the ground to soak up the sun...leaves do really well in the coldest weather...didn’t lose a single leaf all these years to cold...good genetics I guess,Good old stand-by Needle...just lives on its own and never asks for anything...it’s area is moist compared to the others and it seems to like that...

      I have 10 extra Serenoa repens Super Silver seedlings for sale. They are approx. two years old and I germinated them from seeds I got from Christian Faulkner. As this palm is very slow growing after taking months to germinate, you have a chance to bypass several years of waiting to grow one from seed. Silver saw palmettos germinate green and take on their silver-blue coloring as they grow. Info from Palmpedia below:
      http://www.palmpedia.net/wiki/Serenoa_repens
      This SE U.S. native palm is quite coldhardy: down to zone 8. Once considered a noxious weed in its native territory, it is now valued as a desirable component of the ecosystem and a decorative urban asset. 
      Serenoa repens Super Silver: $10.00 each
      Shipping = $10.00 for one plant. Additional plants by quote - ask me.   No shipping outside the US. No shipping to HI.
      Payment via Paypal.
      PM me if you are interested.
