Seed grown Juania australis

[Plantasexoticas]

Hello everyone, sharing here some pictures of my Juania seedlings. Seem to be growing ok for me so far with few problems. 

I know there are a few of these growing around the world, but I'm pleased to have a few to look after.

I have posted these on a few forums now, interesting to see who's growing them and how you are doing with them.

Very rare palm, there...

Yes

The seeds didn't come cheap but were worth it

Thank you Josh. They have mostly been trouble free apart from a little red spider mite but I keep them at bay. One currently is showing variegation - it's just pushing its second leaf which looks the same so I'm interested to see how it progresses.

I didn't grow mine from seed because I couldn't find one but it has been an easy palm so far.

Apparently, it really does resent high night temperatures. Mine spear-pulled in 2015 when we had several nights with 30+C during in a row. It has recovered nicely though and temperatures like that are unusual here.

It is too tender for my climate but makes a good potted palm for some time.

The damage is still visible.

It looks great! Can't wait until mine get that size, got them through their first winter ok and they are growing steadily

Flo, yours looks fantastic. Glad to see some people can grow this very rare and challenging palm.

A friend planted one out in Ticino (southern Switzerland) because we thought they could do well there but unfortunately it was killed by wild boars..

Hi JOSH-O

Have you any advises about how to get good J. australis seed germination rate? I use perlite (almost wet) in a sealed plastic bag...

I germinated seeds of Juania some years ago and from the ten , four showed that pale yellow one of yours shows, and died after a while. I don´t know why this happens to Juanias....

Interesting - how big they get before they died?

I used a very sandy sterilised seed compost. It was always kept moist and I'd check all the seeds weekly to give them a bit of air and clean away any fungus etc that appeared. All of them germinated at around 15-20 celcius

Update on my Juania. Almost a year and half old from seed and doing quite well 

[richnorm]

Nice work!

[Plantasexoticas]

Thank you! I am pleased 

[PalmatierMeg]

Excellent! You have the touch.

How are the seedlings doing?

My Juania is growing away slowly but nicely. I really have come to believe that its reputation of being difficult is due to people trying to grow it in climates that are too hot. The first year I had mine, it spear-pulled after several days of around 40C. It hasn't been that hot here since and the Juania has not had any problems. It is not a palm for typical palm places – that's all.

Very much reminiscent seedlings of Ceroxylon .

[hbernstein]

I wonder if the seedling palms are dependent upon a mycorrhizal community in their habitat to develop. Perhaps the weaker ones didn't have the proper bacteria/fungi on their seeds to give them a good start in life.

Interesting theory. Maybe I'll start using some on my seedlings now to see if it promotes stronger plants

They are doing well, hoping for some more palm like leaves this year. 

 

Yes i I agree with the heat but also find them resilient. One dried up to a crisp last year and went brown - I was reluctant to throw it away and several months later the seedling began pushing out a new leaf. 

I do worry about the heat though - we have a week of temperatures pushing 30 and it will probably be higher in the protected spot the Juanias are in too - I'll be keeping them shades and well watered

 

[Flow]

I reckon they will be fine. Mine only spear-pulled when not only day but also night temperatures remained high.

Ceroxylon quindiuense. Very similar when small.

[Plantasexoticas]

I'm also growing ceroxylon quindiuense and ceroxylon parvifrons. I have to keep the ceroxylon labelled to tell the difference but the Juania I can tell the difference when they are next to a ceroxylon seedling. Very similar looking though and could be easily confused. 

Looking forward to them all getting bigger! They all enjoy being outside most of the year, just need to figure out what to do with them as they grow as they need to be bought in during the worst winter weather!

Doing well thank you! Through their second winter now. Only bring them inside on the frosty nights 

[palmsOrl]

Wish I (or 99.9% of the rest of the world) could grow one.  These are lovely palms when well-grown!

[Tyrone]

Looking really good. Well done.

What’s the max temp they’d have seen and the highest minimum they would have experienced in your summer. I’m very curious.

We don’t usually get much in the way of high temperatures here but on occasions for a week or two each summer we do have some warm to hot days and nights. 

Highest temperature in our summer last year was 33 Celsius - possibly higher on the sun trap of a balcony I have them on. Nights during this period were around 18-22 Celsius. It’s normally around a week or two each year that we get these temperatures. Rest of the summer is between 15-25 Celsius.

[Plantasexoticas]

I do remember being particularly concerned when we had that heat as I have read that high temperatures can kill them - but all the seedlings made it through fine

Interesting figures there. We may get the odd day in summer in the 33C to 37C zone but it may be 2 or 3 years where we never get above 34C fo example. I’ve never recorded a night minimum as high as even 20C in the nearly 6 years I’ve been here. Summer mins are normally 12-18C with the average min around 15C in mid summer. Summers are normally avg mins of 14,15C and avg max around 23-25C.  I reckon Juania may do alright here given what you are saying. Thank you for the info.

During a week when I was away it did get hot and they were not watered well. One dried to a crisp and it’s leaves browned. I thought it was dead but decided to keep it and a month later it re sprouted 

[Tyrone]

They sound a bit stronger than I first thought at least when young.

I have another question. How long did yours take to germinate??

Thank you. I’ve just acquired some seed so am eager to know.
