About my garden I live on the edge of USDA zone 6b/7a We have hot and humid summers and cold winters with occassional snow and ice storms. Everything that appears tropical and is in a container goes indoors or to a greenhouse for the winter. The plants in the ground stay in the ground all year. The massive palms are faux planted in their containers to keep from blowing over, they all go to a greenhouse during the winter.

He compares various species and hybrids, discusses the risks of transporting mature palms, and provides strategies for winter care and root management to ensure long-term success in challenging climates.
Hey, what's up Garden Inference? Oh, that's perfect. Stay there for scale. Jeff here. It's been doing well. I'm great
Got some new palms here. Seedlings. A little seedlings to look at. Oh, and I just realized I have more coming in the mail
All right, so this is gonna be a two-parter. Well, no, it's not. Later on
We'll cut off and I'll come back with the next shipment. I have here a bunch of sable palms
I know. They don't look like much yet. They grow like snails. It's gonna be a while
But eventually these will look pretty cool. I have three different types here
Although I would say it's actually more like two and a half different types. We'll get back to that later
I thought hey opportunity to talk about cold hardy palms
So let's do it. These right here, the ones in these bags, are from Sable King, Texas
If you don't know, it's just a wonderful, wonderful sable person
Sable
Farmer, I don't know
They're on the Facebook and on the Instagram. Very informative. And this is somebody who
Propagates. They get a lot of seeds going from different types of sable palms
So the sable palm in general, that is a broad term, right?
So that's an umbrella term for the sable species. Within the sable species, in the US
We have sable palmetto, minor, and etonia, and then we have lots and lots of variants
Within there. All different kind of subgenuses. So
That's that's gonna be something we have to talk about. Do we have to though? There's a lot to it
I don't know if I feel like it. Just kind of want to talk about these three
But I guess we'll broadly go over sable palmetto. And there's also Mexicana and Brizorian
There's so much to go into here
I really want to focus on what I have right here
But let's just say, in general, what we mostly know in the United States, native to the southeastern United States, a little bit of
Some other parts here and there, is the sable palmetto. Slow-growing, shrunk palm, costa palmate
Frond, meaning that it's kind of like an in-between of a fan frond and a pinnate frond, your feather type frond
Really cool frond. It arches and, you know, has a neat kind of, almost like a Venus flytrap shape to it actually. Yeah
Typically slow-growing, pretty darn cold hardy though
These guys are good. Zone 8 being up where, like, you don't have to worry about them. Zone 8A, you might have to protect them on occasion
Same thing with 7B, 8A, somewhere there
You can give them a try. Main thing is you want to keep them pretty dry during the wintertime
And then anything below like 10-15 degrees Fahrenheit, probably a good idea to wrap them up
Though they can go down, like, briefly down to zero degrees. Even cooler than that actually. So let's get into that
The exceptions, okay? So with cold hardy palms, if you're watching this, you probably already know this
But a lot of us who are into the cold hardy palms, and it doesn't look like it
I'm in 6B if this all goes away to a greenhouse during the winter. I can't grow this stuff here
A lot of us look for seed forms, types
So here's a windmill palm right here, Trachycarpus Fortunii
Somebody who wants to grow this but is really struggling
Maybe you're like really cold, you're a zone 5, zone 6, or these are good zone 7 and up
7B and up
You're gonna want to find some that have been able to withstand some pretty harsh temperatures
So you will find seed from parents that have survived really harsh cold fluctuations
You know, there's lots in North Carolina, and the Trachycarpus Bulgaria is probably one of the most popular
Supposedly hardy down to negative 20. I think that's a ridiculous claim. If it were true, then we would have
Trachycarpus Fortunii Bulgaria growing all the way to zone 5, right? But we don't. I mean they'd be everywhere
But the point is they can take a little bit more cold than just your regular Fortunii
They are Fortunii, but you get what I'm saying, right? Same thing happens with the Sable Palmettoes, Mexicanas, Cosariums
Black Barianas, there are so many different types of Sables
But here mostly have to focus on the ones with subterranean trunks
Which for me is going to be the minor Sable Atonia, not quite as cold hardy
You can see my Sable minors are back here. Quite large, mine grow incredibly fast
These have only been in the ground for about three years, man
Four and a half years at this point, but they started putting up an inflorescence after being in the ground for two years now
tripled in size
Quick growers. It's not always the case though. A lot of Sable minors is one that's supposedly the most cold hardy of the Sable minors
There's lots of debate over these things called the McCurtain. Well, that one grows like a snail. That's why I don't bother with it
But they say it can take more colds, you know, that's one that's grown up in McCurtain County
So if your Sable minor, those are the ones with the subterranean trunks and they don't have this much of a cost to plummet leaf
It's just a fan with a split in it. That's what the leaf looks like on a Sable minor
You have the same thing. So if you have your Bluestone Dwarfs and you have your Emerald Iron Giants, there's just
Emerald or Emerald, you know, it doesn't matter. Lots of variants. What I have right here are
variants
Except I think this one's a lie. That one's from somebody else
We'll talk about it. The Trunked Sables are
Really probably some of my top five of favorite palms. I just freaking love them
You may notice I have lots of big palms
whole bunch, but
No Palmetto's or Mexicana's, none of the Trunked types because they don't ship well
Okay, you can move them all over the southeast but it's difficult to get them up here to St. Louis every single time I've tried
They end up dying very very very slowly
They have a soft heart though
You know heart of palm the piece that grows up through the middle the lifeline of the plant
It bruises easily so, you know, you can drive to a certain distance, but then they need a break so it's possible
I may try and go down to Atlanta and maybe buy some next year or maybe over to Oklahoma
I guess I'm from somebody who's already trucked them up and they've had some time, you know, like a
Halfway point to rest and then bring them up the rest of the way
That might be something I do someday and keep them in a pot because I don't want to risk losing them because they grow like freaking
Snails compared to the palms that I'm used to, you know, they grow like snails the Palmetto does right?
It's not the fastest of growers. It's not horribly slow, but you know, I'm saying it's like a Queen palm
You know just a few years ago. That thing was in a 15 gallon container
Now what's up there and you got to be picky when you're moving your plants around, right?
So if we keep it in a container, I don't want to get in this huge
You know, those are really pretty Mexicana's and what's this really big thick trunks on them or other option grow it myself
Seedlings ship around without too much trouble. It's not too mindful of the root
So in the sable palms you break part of the root the rest of that root dies
Which is another issue that comes along with moving them and transporting them, right?
It's why you often see the larger ones just sold as a stick once they're over like 10 feet or so and trunk
You have better transplant success rate from what I'm told. I wouldn't know him might always die. So that's what's going on here
I have little guys that are different seed forms
They come from parent plants that have shown some really exceptional hardiness or just an unusual characteristic
It took me seven minutes to be able to give enough background information to make that point. That's not ideal. I'm so sorry
Perhaps I should have done a separate video
Talking about the sable palms and that whole umbrella situation with the different types and cold hardiness and then done this one
But hey, here we are. Sometimes it's just fun to talk about plants. So right here, I think
It's hard to tell because they're wrapped up so tightly. I
Think that this is a Bersoriansis. Yeah, that's a Bersoriansis. It's a green form
It says green on here because the seller also has a blue form. I
Didn't that's the time I ordered but I will be checking back because I would like the blue form
So Bersoriansis is from Bersoria County, Texas
And I don't know if it's still considered to be the most cold hardy of the trunking sables
But it was at one time you'll find
Yeah, pretty mixed information on their growth rate
Most people say they grow fast, but they can protect the sable minor and there and there are some people like no
It grows very very slowly. I don't know. These are different things. I'm not sure which is which we'll find out together
The sable Bersoriansis is a hybrid. This has been shown through some actual DNA
Science stuff they looked at the plant and it is sable palmetto and sable minor
Which is pretty close. I know a long time ago
This is considered like a cross between a sable Mexicana and some other things
But now we actually have genetic confirmation that that's what it is
So we have the sable minor which is super cold hardy and the sable palmetto which gets the trunk and for a palm tree
Still pretty cold hardy
Smaller growth stature. I think they'll go like 20 feet or so
If you're not in a really warm climate sable palm growth is always no matter what type you're growing
You're growing a much slower growth on these plants when you live someplace that doesn't have
Well one warm summers and warm winters, you know longer your warm season meaning like over 77 80 degrees Fahrenheit
Really up above 80 Fahrenheit, then that's your growing season, right?
So the more days you have up there the better the more growth you're gonna have I know plant delights
Great resource for plant information. They do a lot with cold hardy palms
They said on their website that there are reports of this one having survived like minus 15 degrees Fahrenheit in Arkansas at one point
That's pretty darn good
Surviving one quick cold snap is not the same thing as being able to survive like my 6b winter unprotected. No, no
The area that palm trees growing in still has a much shorter cold season than I do
So that's something to take into account. So I'm gonna have to keep these potted or
Do something very elaborate with them in the ground some day
But since this is a hybrid
I'm not gonna expect them to get anywhere near as big as your regular stable palmetto height wise
That is probably get pretty darn girthy
They look like they get some good chunkiness to them and I have seen these before in the ground not where I live
But they're absolutely beautiful palm tree. So that's the cold hardy
reasonably fast growing
But probably very thick and chunky brazoriensis
Cool palm tree, right? Well, that's where we get to these two right here and then the one back there
That's a lie, but we'll still talk about it
These right here another awesome stable hybrid
We think don't know for sure. This one hasn't been checked. Genetics are still a mystery
These are the sable
Diffuniac which is a sable from Diffuniac Springs, Florida
Stays small relatively small. I think it maxed out around 20 feet high and grows very quickly
Supposed to be the fastest growing of the hardy sables
They think it's a cross between a sable minor and a sable palmetto, but possibly a cross between sable palmetto, sable etonia
Don't know but it's a smaller statured palm. So 15 to 20 feet tall and
Quick to grow that is what us cold hardy palm people need. We need fast growing palms
The reason for that at least for me why I prefer the quick growth is because their speed really
Dictates how quickly they can recover from a really bad cold snap
So I told y'all I don't bother with the sable minor like the mcCurtain was never interested, you know
I had one it was cool had a bad winter and it took a year to regrow like two fronds
I don't have time for that. Same thing whenever I've done palmettos in the ground. I have a sable palmetto
That's been in the ground for me. It's behind me for about 10-15 years and it's you know, I don't know
four feet tall
It's not worth it. The juice ain't worth the squeeze. I don't do a ton to protect it either though
It basically dies down to the ground every year and comes back
You know, I could do more to protect it and I have a much bigger palm
Then there's the sable Birmingham, which is another one of these probably
crosses probably a palmetto and a minor that's from Birmingham, Alabama survived a really really drastic cold snap and
The seedlings from that plant were at one time really really popular
Some things are as popular as they used to be because people want to grow up for its cold hardiness
But it grows so freaking slow. So so so slow. So of course when I tried my sable Birmingham
Didn't go so well. I don't have the patience had a bad winter and it same story
You know had to wait the rest of the year for it to get like I don't know
It had maybe three fronds on it by the end of the growing season. That's all it had recovered
It's not worth it. Can't do it. But right here at the defuniac fast-growing and
Probably a hybrid from looking at it. You look at these mature pictures
I could see how there might be some sable minor or atonia genetics
And if you don't know the sable atonia don't really talk about that's also a subterranean trunked mostly
subterranean trunked palm like the sable minor
So all of these things are characteristics that just make the palm make more sense
If you're in a situation like I am
Where you're probably going to end up keeping this plant containerized or if it goes in the ground it needs to maintain a size
That's reasonable to protect right? I don't bother with Washingtonia's in the ground anymore
They can survive our winters if you wrap them up really well and you keep them dry during the winters
You need to use like lights and heat on them to get up through the winters
But within five six years, they're just too big. It just doesn't make sense anymore. It becomes very difficult to protect them
These right here. They'll max out 15 and 20 feet, which is still a big palm
But in a container, they're not gonna do that
I just want you know a few feet of trunk and some giant costs of palmate from that's all I'm asking for
Some nice bootstraps a little zigzags on the trunk that classic sable
Look be able to get that with these they say that this one will flower in as little as five years, which is awesome
For everybody in the cold hardy palm community who are constantly trying to hybridize things
It really speeds the process up if you're trying to cross sable palmettos and things like that
You gotta wait a long time
Then we get big enough to flower could easily back cross this back to a minor and see what happens with those seedlings
You can play around with things more and it's nice that there's a trunked sable that will put up an inflorescence that quickly
Create more options. It's gonna be more slender. So this would be more reasonable to move around a container though
It will be big and it will be heavy
Kidding me. I mean, you know, I move some big palms around
I'm not too concerned about that and I have more coming. So I have two also coming from plant delights. They're both disabled to phoenix
So they should be
From the same parent plant and I should have a very some more plant
But I just think it's good to cast a very broad net when playing with cold hardy plants, especially cold hardy palms
You need cast that big net so that you have lots of different
Variables to place you end up which isn't like the best thing for experimentation
but as far as just being able to nail down which is most cold hardy usually having a large sample size is good because you
end up losing some along the way and I should also mention why the crossing of a
palmetto
Really any trunked sable palm with a minor is important to me. It's not just a cold hardiness. It's also
The conditions that they can grow in so sable palmetto they can grow the swamps and everything
They can take plenty of water as long as it's nice and warm, but you have a wet winter
Just dead wet and cold. They don't like it
But when you have the minor and they're with them sable minor
One of the reasons I love them is because they handle our drought very very well and they handle our wet season very very well
So they're just versatile. I can put them in the shade. I can put them in the sign
They're a very tough plant in that regard and you end up getting some of that with these hybrids
sometimes not always but with the
Diffuniac and the brazorian says they seem to be much much much more tolerant of a wetter soil
It doesn't mean that you should grow them in wet conditions
But it just adds a little bit of extra assurance for me as the person who's going
Uh-oh, if we have you know a really wet winter, you know, I would keep these protected
I'm not as worried about them just running out and dying as I am with a like a palmetto remember
I'm talking cold and wet and when I say cold I'm talking, you know
Well below freezing right where things are frozen and then you know, it's 15 degrees at night times. Everything's frozen
There's ice there's snow and then during the day, maybe it's 40. Sometimes it's 50
We have swings like that all the time and everything thaws and that's wet and then it freezes. It's awesome
That's gonna kill any of these probably it's definitely gonna kill a palmetto
So, you know, I'm just hoping that they can handle fluctuations and some moisture better, but in the wintertime
It doesn't matter. I'm gonna try and keep them dry on the drier side of things. That makes sense winter wetness
And ice obviously are some of the biggest threats to growing palm trees. So it's pretty easy to avoid those
I'm gonna be repotting these into gallon size
Containers you see I already have that other one set in a gallon pot
I'll do that with this one to just help hold them up. It's gonna be a pretty lateral move
Not really gonna be upgrading their container size, but I just prefer a plastic pot
don't have to worry about them tipping over as easily as that and I sliced the bags when I was
Trying to unbox them trying to get all that wrapping off. So they need to go into
something like this anyways and
Another thing with sables
I told you you cut a piece of the root the rest of root die
So when you're moving them around and stuff like that, it's best to do that at the size like this
Really you want to make sure they have multiple roots before you start moving them and do it very very very very gently
Try best to not tear up any of their roots. And once you put one in the ground, it's good
That that's probably gonna be the spot where you keep it, right?
You don't want to transplant them particularly the sable miners because they end up having a really long trunk underground
They become difficult to dig up and move
So I have two more of these coming and I will not now but in a few years
I will be putting some in the ground and protecting them during the winter and
Seeing how they do and then I'll keep a couple of them in containers
I won't be doing that until each one of these is
Decent size actually probably about the size of this one in the back. We can talk about that one now the I'm gonna say
allegedly possibly
Fraud palm, I'm not gonna say a ton about this one just yet because I really want to do some extreme deep diving on it
This is a we'll say controversial palm. I only got it because people keep asking me about it and I'm like, well
Let's get one in
Find out I have one for visual representation. We'll get to see how cold hardy it is
Sorry dog needs attention. It's been one on Etsy for a long time and it's called the sable Oregon hybrid sable, Oregon
Don't know what that means. They claim that it's surviving the cold high desert like zone five or six
I don't know. The claims are pretty intense with it and
They feel unfounded. I'm not gonna say if they're lying because I don't know
But with all the other palms all of them, there's always a picture of that parent plant sable Birmingham
there's a picture of that original parent plant where it survived that horrible winter and
The same thing with you don't do to phoenix and there's tons of pictures of the
Presoriensis, you know, I have some other sables. There's a sable
Over there. That's a cross between a palmetto and a cassara. That's from cassara and I can never say it but it's from
Somewhere in Georgia that survived a really cold snap. There's a picture of its parent plant where those seedlings came from. I
Can't find this supposed sable palms that are I guess growing in the high desert of Oregon
Now there's a picture of a larger plant
That looks like a you know, it doesn't look like a straight-up sable miner looks like it's you know, maybe sable, Louisiana something like that
Can't say for sure
Yeah, could be a palmetto. It's too small to tell right now with sable miners
This is typically what your leaf looks like they have a split in the middle
But more of a fan shape
This is too small to tell and I have grown plenty of palmettos from seed size and they will have the split leaf
When they're smaller sometimes, so I don't know but usually that's just a couple of leaves. This one has one two, three
Four of those split leaves on it
But I don't know this one's looking like it's gonna be more of that cost of palmetto shape on it. I
Don't know we're gonna grow this out get it to be a larger size and examine it some more and I will do a deep
Dive and a probably a full-on video on this one with the claims and you know
See if I can find more evidence and y'all are gonna be able to help with that, too
It's another reason I included this in this video instead of waiting to do that one separate weeks
I thought hey people are gonna have stuff to add with this
About the sable Oregon hybrid. It might be a hybrid of sable palms. It's been growing in Oregon. I
Where are the parents where's the big sable palms that are growing in Oregon? I'm not talking about over in Portland
They're talking about the high desert where it gets cold
I'd like to know I want to see those pictures. Maybe I don't look hard enough
So that's what I'm saying
I'll be a different video where I will deep dive
Maybe have some feedback from y'all to go off of when talking about that palm and worst case scenario
I mean I have another sable palm here and I love the sable palms all of them
I also have a black bariana and then I have that sable palmarum, which is that cross and then there's another one
That's called fat chance
that I have and I have lots of sable miners right because I say this is a good selection of ones to work with as
Far as you know testing cold hardiness, and I'm mostly excited about these because these two right here the daffodil acts
Hopefully we'll have some nice sized trunk palms with the next I don't know
decade
Yeah, so comment down below. Oh wait. No. No. No, hold on this video can't be done yet
I got to get the ones from plant delights. I'll unbox them so you can see
You know a comparison between the two they're gonna look very similar though. I would imagine there
You know, it's probably from the same parent plant. They should be. All right. Hey, it's raining
So we're gonna do this inside the other palm just got here from plant delights that daffodil
sables and um
These are freaking huge size wise though. I'd say this this is gonna be the winner. I was gonna say bang for your buck
however
Shipping from plant delights is no joke. I don't see my
Shipping costs on here, but I think you know, it's like at least 40 bucks
I'm pretty sure just have a couple little plants. It might have been 30, but it's it's pretty pricey
So, you know, they do end up being a lot more expensive, but these are Wow
Really nice big plants. Oh, okay. Well, hey now we have the comparison
Did you know?
Whatever you want to do, like I said, these do end up being a lot more because of shipping but Wow
Good looking palms
Okay, I'm gonna take these outside and get the paper off of them. It's raining. So good time to receive plants
Hope everybody's doing well in a great day. Great. Everything's going beautifully for you comment down below
Let me know what's going on with you and your hearty palms your sables. That's not rain that bad different palms
You're experimenting with you have favorite varieties
Pretty sure I mentioned some of mine already the ones that I have
My collection just keeps on growing. I don't want to stand up. I think I'm gonna see a skewer stick it through
Just lay it down on the side for now. Yeah. Hey as always and most importantly everybody keep on growing
Here's that palmarum
That's a nice one
