Just got 3 seedlings.  It will be interesting to see what happens with them.  Hopefully a male and 2 females :)

Still growing like a crazy thing and not yet 4  years old, Ive planted another 4 around  the land, one underneath this one, flowers  profusely now in fact constantly, shoe is  size 13 U.S for trunk scale

These have proven to be as leaf hardy as Hyphaene Coraicea FYI for anyone looking to try them out.

Do you still sell Medemia?

Yea, they have done so well I just put another 100-ish seed down to germinate another crop.  They would have zero issues even in North Lakeland as I remember seeing a few H. Coriacea around town there. I think there were a few on peach Tree street in a park next to a small lake.

@TexasColdHardyPalms Very promising!  I lost my seedlings, but I've never been great at taking care of things in pots.  Once it's in the ground I'm good to go.  I'll order off of you when I have a bed ready for them. 

I keep losing mine to rot in the greenhouse.  What temp do we think a small guy will take?

I would keep them at 60° or warmer until they are at least 3 years old. My seedlings like to be kept very dry. This species is the most drought tolerant palm I've ever grown. Mine will be 2 years old this summer. I might expose some of them to colder conditions in 2019.

Good luck with yours Ben!

Hi 83°, Lo 49°

All of my one year old plants saw 21 this year inside a cold frame. They did burn as did hyphaene, and latania. Vetchia all died, most bismarckia only had very minor tip burn. 

These are really cool looking palms. Can't believe how fast they grow. I'm going to have to try one again. Nothing but bad luck for me so far. Everytime they rot for me even in the heat we get out here.

What's the secret to get these growing from seed? I have failed miserably with 12 germinated seeds. Germinating in a baggy works well, but every time I pot them up the root just rots and disappears. I've tried sand, pumice, vermiculite mixtures in 14" deep tree pots. I've tried putting them outside, leaving them in a dark warm place in my house, and on a heating pad. I have tried letting them dry out a little bit, others with just tiny amounts of water, and a few kept slightly damp. Nothing has worked for me. @TexasColdHardyPalms, I will buy seedlings from you if you tell me your secret!  I have had tremendous success with Hyphaene thebaica. I'm 3 for 3 with those. Growing conditions may be similar for medemia and hyphaene, but germination is another story completely.

Since your climate is almost like mine, my method should work for you:

Soil - 80-90% coir, 10-20% pumice

Water only when 1-2 inches are dry on the surface

Sun: 70 - 100 %

Temperatures: Low not below 60° F at night and at least 70° warmth every day when young

Good luck!

Hi 92°, Lo 51° - ultra dry (< 5% humidity)

I finally have seedlings!  I got home from vacation yesterday to find 2 little sprouts and roots coming out the bottom of the 14" deep pots! I also planted one of these in my front yard in blazing hot AZ sun a couple of weeks ago. I have my fingers crossed for that one!

 

I have one that's been in ground for almost a year and a half in full sun and it's loving it! Not the fastest grower but looks nice, and has a great blue coloring

I would love to see. Pics?

Sure i'll post a pic when i get home this evening. 

Anyone growing these out here?  I have a seedling, that's done absolutely nothing.  I think that it's put out like 2 leaves, in 2 years, and I haven't seen any movement in forever.  I've tried a number of spots, from shade, to sun.  Heat?

Like i said not the fastest but definitely not the slowest. I think maybe its only been a year since i put it in the ground. Getting some shade finally at this time of day. 

Trying to show the blue coloring. 

The one in the pot in the foreground is about the same age. 

Thanks. Nice photos! I have heard they are fast growers in the dry heat. Maybe they pick up speed later? From what I found around the web they have a growth rate comparable to bismarckia and hyphaene. At any rate, it will be fun to watch!

Absolutely! Keep us posted on your plants progress too.

mine are watered daily and its humid heat in Thailand

Any photos of them now? Thanks

I'm bumping this thread for 4 reasons:

1. Did anyone ever figure out where the thread creator (Hal) was growing that healthy looking palm in Phoenix? The railroad track and asphalt parking lot suggests an       industrial area.

2. Does the incredible success of @Tingtongthai prove it doesn't need a dry and hot climate?

3. Can we believe @TexasColdHardyPalms assertion ('18):
   "All of my one year old plants saw 21 this year inside a cold frame.
   They did burn as did hyphaene, and latania."?
   Did his survive until the Texas '21 February weather disaster?

4. Since I transplanted my remaining seedlings to 2 gallon pots today,  I'd like to hear from any thread readers for their feedback (especially desert growers).
   
   Hi 104˚, Lo 79˚

Edited August 7, 20214 yr by Tom in Tucson

Here's my double medemia planted from seed directly in the ground in Spring of 2019. They are in full Phoenix, AZ sun. I lost all of my potted specimens. I think being in the warm ground surrounded by the rock is what got these through the winter. The record breaking heat of last summer did not seem to phase them at all. In fact, I saw a huge growth spurt during the hottest weeks. I turn off the drip completely when overnight temps dip into the 50s and turn back on when they get back up to the 60s. I think I have given up on trying to grow them in pots. I tried every method I could to keep them alive. I brought them inside during cold nights. I tried several different soil mixes and watering regiments. I've lost at least 20 potted specimens. I even tried splitting the pots and planting the whole thing without disturbing any roots. When that one died, I planted a seed directly into that buried pot. I gave it a few weeks. After seeing nothing I planted a second seed. Then they both popped up and that's why it's now a double.

Lots of valuable observations!

I may try that ground germination method the next time I start some seeds. I broke a lot of roots when separating 2 community pots yesterday, but the one with 6 plants looked the healthiest of all of my seedlings. Too bad these probably lost too many roots to survive for long. I should have re-potted a couple of years ago.

Good luck with yours!

Hi 99˚, Lo 74˚

I was working in my front yard today and I noticed that I should probably give my Medemia its first major trim. Then I saw the drip head was dry while everything else in the yard was wet. Apparently I forgot to turn it back on after winter. We had a really cold and wet winter but no rain since early March. I guess I've tested the drought tolerance! It's turning out to be a perfect specimen for our desert conditions. Getting them started is the hard part! This is 4 years of growth from seed.

Just got 10 seeds of Medemia argun from an overseas source. Based on what I've read on this PT forum and online from other sources, a few of these seeds I'll plant directly out in the garden and a few will go into deep treepots. That should help deal with the long taproots of this species during germination.😉

Heres  your 2024  update, I planted another 4 in 2017 this one (biggest) is the original its  my  tallest tree of  all my trees 350+ I posted when it was very small..........Its huge  now and the others are also VERY large and FULL of seed, its produces masses of seed  regularly, got 3  females 2  males and one small one  about 5  foot unknown at the moment, 2males flowering  3  females all with seed. Males seem to grow  faster taller than the females from at least my group of 5. Rainy day in Thailand 33c shoes size 10UK thats one of the females ( smaller) For scale ( wife  not available) the small one  just behind the big one is 6 foot tall (2nd  photo) i  the background of one photo you can see my  wall 2metres high and some bizzies

Jeez, they look amazing! They sulk (at best) in Miami's climate.

Beautiful specimens!

Here's an update on mine here in AZ. They are finally putting on some height and speeding up. I would say they have doubled in size since my last photo from last summer.  They seem to be thriving on very little water. I'm excited about these as many of my other palms are suffering from the excessive heat we have experienced over the last couple of years. I'm slowing replacing anything that dies with proven desert species. And Medemia is proving to be rock solid. Zero heat, cold, or drought damage.

 

I have enjoyed reading this thread, not a whole heck of a lot of information out there on these palms. Here is mine in Casa Grande AZ planted 3 years ago as a strap leaf seedling. The first picture was from its first year after about 5 months in the ground. Notice the size compared to a sprinkler drip head. The second picture was from a couple of months ago. Routinely sees mid-20s in the winter and smiles on our hottest days.

A little update on one of my 2 Medemia Arguns. First inflos!  Only one of the 2 plants is blooming so still have my fingers crossed for a male and female.
