It's C. seifrizii. Very easy to difference them. C. costaricana looks like a slightly smaller version of C. tepejilote. But it's still very robust, and their flower/fruit bracts hang, while C. seifrizii bracts are erect. Also the ligules, only 2 species of Chamaedorea (including costaricana) have ligules. And the location too, to my knowledge, C. costaricana can't grow in Florida's soil due to nematodes or sandy soil, while C. seifrizii can tolerate FLA soil.

I think I have 30 and a couple more in pots which I may as well plant!

It is sad to see how my former home me and garden has declined from the present owner, it has been great to see how many offspring of the Hedycepe have grown up around the world from seeds that I dispersed over time. The ones that I have now are 3rd generation grown from seeds of a friend that has 2nd generation palms that I supplied years ago. 50 years ago I planted my first one! So I am planting more now in my 13 year old new home and garden. The passion remains the same as it ever was!

Here’s a Syagrus x costae (S. cearensis x coronato) in the front garden a couple of years after planting and today, nearly 20 years later. These typically produce massive inflorescence but mine hasn’t flowered yet. It resembles a thin trunked more plumose Queen palm.

A nice time to be watering the garden, with temperatures set be close to 49 degrees Celsius, water as much as I can now for the humidity, that’s one trick with growing some of the super jungle varieties I have!

A few confusa that are turning out to be quite happy growing well. They seem to like what iam doing and there microclimate in the greenhouse, iam kinda glad I got another hundred seeds the other week. Another smallish dypsis for the understory in the garden!

I have grown a few batches from these mother palms in south Tampa on Swann. They take cold down to mid 20’s under canopy at my place and in 25gal containers have grown 10’ plus. How does one tell the difference between the two?

Some of the specimens in this garden.... Just had to share.

I believe that the second species, C. quezalteca has been reduced to synonymy within C. costa-ricana.

Most palms sulk if planted from containers in the ground. But water is one trick in the warmer time of the year, some winters I hardly water my garden and in the nursery I try not to water all winter if I can help it. Richard

You can expect around 3 leaves per year depending on your winter, they are slow in the ground in my climate. And they love water the more the better in the ground with good drainage. And they love warm soil temperatures. But they are slow regardless of conditions, definitely a super hot tropical lover!

Colin, My hillibrandi has much longer petioles, less leaf curvature, larger fronds as a juvenile, and considerably faster growth than the Pritchardia whose identity is in question. I’m leaning toward P. glabrata so far. Whatever it is, I’m enjoying watching it grow, even as slow as it is.

Looks kinda like Timʻs glabrata but Iʻm thinking more like hillibrandi. Many of the Pritchardia in my opinion do not alway show the lepidia until more mature. Have seen many small marti and bakeri in habitat with no lepidia. Could be due to the harsh natural environment at higher elevations here Pritchardia is a very hard genus to figure out when young. aloha

I agree with @idontknowhatnametuse - C. costaricana has very attractive, wide leaflets, closer to C. tepejilote than any of the usual Chams you seen in Florida. Unfortunately the last statement rings true as well, as this one has languished in the ground, I don't know if it's the soil or the heat, since this is a fairly high elevation species. C. seifrizii is from the Yucatan and can adapt to full sun in Florida, although it looks nicer in the shade. I've frustratingly had a lot of fungal issues with this one in the landscape however. They seem to fare better when they get some sun on the leaves so they can dry out more quickly in the summer.

It certainly saves your memory as you age.

Clinostigma samoense in a light drizzle. One of the world’s most beautiful palms. Tim

Let them invade!

Another one

From my trip to Andean Peru in 2013 - a group and a closer-up single:

Love them or dislike them, there here to stay in a garden near you. We all know how tough they are and the yellow colour is what sets them as winner. The only fault they have is drop leaves like a hot potato in butter fingers. But they are proven in the palm kingdom as the magical beauty of a palm up there with the coconut as picture of tropical holiday by the sea or poolside. I still grow a few and will still a few around as pioneer palms to help establish new plantings. Theres even a dwarf form worth tracking downl to grow!

49c dear ? We had a 39c a couple of weeks back but mainly mid to low 30s lately. Very humid of course but the rain only comes with nasty storms. I am using the sprinkler again, even though we had so much rain in the past few weeks, the soil just dries out in no time. Your bird nest fern looks good. I had 2 that were enormous at my old house but I can't get them to grow here for some strange reason. Peachy

The trick with golden canes is plant them out as singles, the standard dozen in a container from the plant store doesn’t work well when mature, one great big ugly clump, but plant them out as single ps it’s a different story! Richard

They seem to be pretty popular with the cool climate growers and just about everyone who grows palms would have one or two around their house. So easy to grow and propagate there fast becoming the modern day chamaedorea elegans. Very tough dry tolerant cool tolerant and fast to grow, is one reason they are popular, from medium amounts of sun to deep shade there a palm that fits into any garden or container!

Powerful trunk, so thick 🤔🤗

Nice one gyuseppe good looking palms!

There seems to be a myth about how joeys have a reputation for just up and dying for no reason. I have a few and from observation, it seems the weakest in the batches after potting up have the middle new leaf die. It’s not root disturbance, it’s possibly a soil fungus. I call it flagging as you can see basically a flag signal with the new dead leaf. I have broken roots of new seedlings and they will die. But that’s a grower mistake. So I use a foliar soil fungicide once every 3 weeks. So hopefully this gives a reason for joeys just up and dying. Eventually in the potted up batch’s the weakest have been eliminated and you dont get them dropping off dead, with just the strongest surviving.

Thank you both

I think the gents above have it correct. My neighbor's psuedococos is a bit more robust looking. For whatever reason, despite otherwise growing well, his suffers a lot of leaf burn. Kind of an anomaly in his yard, as he has water and fert pretty dialed in. But the trunk on it is a bonus; a beautiful chocolately color with nice distinct ring spacing.

This palmetto is pushing a new frond after this MASSIVE strap leaf. I should be more like @kinzyjr and put dates and labels on these things instead of having to dig through this thread to figure out when I potted it. Honestly had no idea if these would even sprout, this was just a FAFO experiment. Large variety clementines from Peru I bought at a Mexican market. I really hope it wasn't too premature of me to bring these all out here after yesterday's spider mite spray bombing. Dragonfruits Bien Hoa, Condor, and Laverne Red plus Red Lady papaya and a Mona Lisa banana. I think they'll all be a lot happier in this sweat lodge. Poor little things died before they ever had a chance. Pour one out for this week's dead homies, a couple grocery store papayas and some mango seeds that rotted. Big mama colocasia is pupping again and so are her pups - so onto this This damn thing just doesn't want to be built and it's adamant about it. I literally need to buy a new set of drill bits because I've broken all of the small ones. I really miss the good old days when Craftsman was sold by Sears and you could go in there with like, a wrench that has been floating in the ocean for 11 years and on the spot they'd give you a replacement. Anyway that still wouldn't matter because these came from Harbor Freight and they're probably made out of glitter and yak farts.

I really need to rethink my Hedy quantity. 🤣 -dale

Nice one my possum, they are actually tougher than magnifica. I have had less trouble with perakensis than magnifica, they are trouble magnifica but iam working them out, one thing with a Joey I know is once they get a setback they take a long time to recover from any ailments. There’s a seller called @happypalms out there I must get his number, but between you and me I hear he has killed a lot of exotic palms in some kind of zone pushing experiments. But you know what good on him for giving it a go the world needs more happypalms,. Richard

Jim I think the best I could do is rule out a few possibilities. From the photos it looks to me to be solid green on both sides with leaflets spread about 180 degrees around the petiole. I’d expect species with abaxial surface completely covered in lepidia to start showing at least a little bit at that size, which would rule out P arecina, hardyi, martii (and the old gaudichaudi), minor, perlmanii, flynii, viscosa and maybe a couple of others I’m forgetting. The leaf shape I think already rules out maideniana. I think the blade is already showing it will be significantly undulate rather than mostly flat so I’d say beccariana and lanigera are unlikely (although this is where I’d stop at ruling them out completely). Also the fact it’s still alive probably rules out non Hawaiian species! Not sure that helps much - there’s still about half of the species I can’t rule out. For what it’s worth, P hillebrandii that I’ve grown and seen at that size are similar to yours, whereas P martii, napaliensis, minor and maideniana were already visibly different (although that could be partially due to growing conditions). P napaliensis tends to have smaller fronds relative to trunk size at that size based on mine and others I’ve seen but again I couldn’t conclusively rule it out.

Hmmmm, here’s a shot of P. glabrata about two years after planting from a one gallon back in 2012. It had not yet developed the pendant leaf tips. Not sure if this helps or adds to the confusion. Tim

I agree with @happypalms , a bit more time . Once they go full pinnate they seem to gain speed . I have not noticed any difference in speed on my full shade Radicalis. I have had tight groupings such as that and usually 3-4 will take over and the others will fade. They are easy to separate but it is winter for us now so best to let nature take its course. They will be lovely as they grow. Harry

the seeds are double compared to seeds of radicals forms small

Thanks, the crazy thing is I just purchased another 100 seeds for something to do, I just love them that much!

More from my Latania collection

Thanks Darold! Hope to recreate something like this in my yard 30yrs from now; a wild and free garden where to get lost

That’s a chunky Chamby frond Dave! Here’s a 28 foot P. torralyi frond stretching across my entire front lawn area that I just removed the other day.

Some nice colour for the garden ready to go in the ground.

is seifrizii

Mccurtain is surprisingly fast growing (I think), got that big and to 2nd spear by now. These are actually the stronger ones, the other one did have this problem but I watered it and it perked up instantly. These on the other hand didn’t. Think it was the 23F and dryness to 80F and wet that made it like that

My small plant is growing well for me in SF, so far it's the fastest of any of the New Caledonian palms I've tried, at least in terms of leaf production. I might have gotten lucky with a robust plant based on what others say about speed, mine has opened three fronds in the past year, compared to one leaf every nine months or so for Chambeyronia and Burretiokentia. Maybe a concerning data point for Florida growers!

This is very validating because I have noticed the recurved and the flat planish shape. However, I purchased from a super reputable source so I didn’t doubt it!

I'm ready for a mild winter 🌴, betting on 31F at IAH and 33F at Hobby for the season 😆. It sounds hard to believe with the recent cold blasts but 6 out of the last 15 winter seasons have been zone 10 at IAH and/or Hobby. If we go back to the 90s and 2000s it's even warmer! 2019-2020: 30F/32F 2018-2019: 30F/31F 2015-2016: 32F/34F 2014-2015: 28F/30F 2012-2013: 29F/31F 2011-2012: 29F/31F Ready for mango trees and royal palms🤩🌴.

My little joey on a stick (J perakensis) has survived a year that killed so many of my other young palms. Not only survived but has grown a lot and looks fantastic. I bought sight unseen from the internet from a man called @happypalms if you are looking for a tough and unusual little palm. Peachy

Your Syagrus looks much more like Syagrus botryophora

Haven't posted in a long time - thought I'd share my Southern California coconut pictures. I purchased this as a sprouted nut back in 2007 and planted it in a whiskey barrel full of sand. I planted a few others outdoors in a similar fashion, but don't think any lasted more than a year or two. I've tried a few other marginal palms (spindle, bottle) which I was able to limp along for a number of years - but this one is the sole survivor. It was in the whiskey barrel until about a year and a half back the barrel was simply disintegrating, wouldn't hold water, etc - so after digging a really big hole - in the ground it went and has done pretty well. If you look up some of my older posts I've posted a number of pictures throughout the years. Definitely not setting any speed records, but fronds/petioles have definitely started thickening up since it went in the ground.
