germination Lytocaryum hoehnei

[Pal Meir]

Two weeks ago on 2016-08-04 I got from Kai @Kai five Lytocaryum hoehnei seeds. Today – only 15 days later – the first seedling showed its still very sleepy looking eye:

[Kai]

Congratulations! That is great news!

I'm sure a detailed photo archive will follow on this newest addition.

[Pal Meir]

Oh, I made a mistake: Kai shipped those seeds to me on 2016-08-06 and I received them 5 days later on 2016-08-11 (it’s a long, long way from NL to DE, perhaps 200 km). Therefore that seed germinated only after eight days since arrival.

[Pal Meir]

Yeah, this seedling does not only look sleepy, it is also very taaardy . Yesterday it opened its eyelid and today it is looking a bit afraid:

[Pal Meir]

And this seed is shedding tears because it is rotten:

[Pal Meir]

As I fear I’ve fried  my remaining L hoehnei seeds under the SoCal-like burning German sun  (@Kai forgive me, I forgot the pot with the seeds standing in direct sun on my balcony! ) I’ll post here photos of seedling N°1611 that I got from Kai on 2016-08-04 who had germinated it in beautiful Amsterdam on 2016-03-02.

Pic #1 shows the seedling after removal out of the deep 7x7x18 cm pot, with a tiny eophyll, ready for pasting my germination labels on it:

I repotted it the same day in a smaller 8x8x9cm pot, using my L insigne soil mix with 1/2 Seramis® + 1/2 pine bark 2-8mm + 1cm LECA layer on the bottom. – Ten days later the tip of the 2nd leaf appeared; pic #2 shows it one week later and pic #3 after two weeks:

[Kai]

Pal, please don't give up on the seeds yet! In my experience these seeds sprout after a period of very warm temperatures and then being brought back to normal room temperature.

I asume the first germinated seed is still ok?

[Pal Meir]

Showing the tip of the 3rd leaf 218 days after germination:

[Pal Meir]

Happy birthday, N°1611!

[Kai]

Yes, very healthy Pal! Very good to see.

[Pal Meir]

And 3 months later in a big Ø14.8xH17.4 cm pot, still only with strap leaves:

[Pal Meir]

1½  years since germination: Will leaf #6 go pinnate?

[Pal Meir]

2 years since germination, pushing spear of 7th leaf; 6th leaf is partially pinnate on the right side of the blade:

[Kai]

First partly pinnate leaves appearing on my hoehnei seedlings. It's great to finally see this happening and gives my anticipation on the seedlings growth a new boost!

Very nice! My N°1611 stands outdoors on the balcony since March; so it is growing only quite slowly ……

Very good, let it get used to higher uv levels.

[Pal Meir]

Today the tip of the 8th leaf became visible. And leaf #7 is going pinnate on both sides of the blade.

[Pal Meir]

And another 79 days later the 9th leaf is showing its tip:

 

And this is the appearance of the whole palm, still looking quite small in its large 2 liter (Ø14.8 cm H17.4cm) pot:

[PalmatierMeg]

Great work and great tutorial. I have a large one of this species but would love to try it from seeds. However, seeds are unavailable.

[DoomsDave]

Oh, yes, one of my favorite small palms. Looks like a miniature 800-pound gorilla, and, so far, none of the diseases or other problems. And, small enough to squeeze into a garden that's been thoroughly Velezed^TM.

I can’t wait till it looks like this one (©Mauro Peixoto): 

[Kai]

I can't imagine how you would place it on your balcony next to your enormous insignes...

[Pal Meir]

After two months leaf #10 appeared:

And a close-up:

looking super healthy, I understand this one is even hardier than l.insigne

But it’s growing much slower.

And after over 70 days pushing its 11th leaf:

[Pal Meir]

Today 3 years old:

The growth rate is much slower than L insigne’s and even L weddellianum’s.

[Kai]

Perfect growth! I didn't expect anything else from you, chappeau!

[Pal Meir]

Tip of leaf #14 emerging:

[DoomsDave]

I've found hoenhei to be much more tempermental than weddelianum, and needing much more water and shelter from the sun. But they sure are hupsch!

[Kai]

Very nice growth Pal! That one will soon be flowering alongside your weddellianums!

[joe_OC]

Pal...I really love and appreciate your palm seedling growth updates.  Fantastic job of growing.

The sun-tolerance of the 4 Lyto species seems to be (from most to less tolerant):

(1) L insigne, (2) L weddellianum, (3) L hoehnei, (4) L itapebiense.

I was surprised at the sun-tolerance of L weddellianum.

[Kai]

My large wedd got horribly sunburned in the summer of 2018. It still has to loose some of the (partly) burned leaves, but it's starting to look better again. I tried to acclimatize it for a long time but still it got burned in just a few hours time of direct afternoon sun. I don't think I'll try it again, it takes a long time before it's proper again.

I had the same sunburn experience  with my L weddellianum N°1305 last year which came directly from the protected desktop onto the balcony. — The leaves of the two palms most exposed to the sun changed a bit their appearance: N°1308 got very delicately curved leaves  and N°1302 darker and harder ones.

Seeds of L. Hoehnei seems to be completely unavailable just like Itapebiense. They are listed on RPS though, so maybe they will be accessible at some point.  

[Pal Meir]

Not the fastest grower. today 4 years since germination:

[Pal Meir]

Leaf #16 emerging:

[kristof p]

Today I picked up my baby L. hoehnei at my parents place and when I got home I immediately put the seedling in a new soil mix containing 50% pinebark (2-8mm) and 50% seramis. I used a small palm container (7x7x13). On the bottom I placed a layer of broken pot shards for extra drainage. It was growing in organic soil and the roots looked healthy and strong so I hope she will adapt fast to the new soil.

I placed it in front of a large window at room temperature (16°C-22°C).  

 

roots looking healthy.
