Zone 7b palmettos?

Recommended Posts

Besides the well known Bald Island ecotype, Plant Delights (NC, USA) nursery had the Mt. Holly, Rock Hill, and Tifton Hardy palmettos on their website. Any experience with these?

You seem to be in 6B.  I have a small Palmetto in 7A and it will need some protection.  In 6B most winters it will need to be covered.  it will take 3 years for you to have a 3 foot tall palm from the Plant Delights ones.  Here is a pic of mine after about 3 seasons from Plant Delights.

Yes I'm in 6b. I appreciate your advice. I'd love to try a palmetto, but I was mostly wondering if folks in slightly warmer areas than mine, had tried these palmettos grown from seeds of survivors of cold snaps (grown in areas colder than the native range). I thought this might be a good topic that hasn't been covered before. I've seen topics on Brazorias, Riversides, Birminghams, Louisianas etc.

I don't remember anyone on here with one from Plant Delights more than a few years old.  They are more cold hardy when trunk is at ground level.  They take many years to get a trunk of any size.  Most trunked Palmetto you see are dug from FL where they are like weeds but may be many decades old.  Palms grown from seedlings in a colder area will be more cold hardy because of their better root structure than palms put in at a larger size.   Palmetto are a 8A palm and I know PD says 7B on some but who knows.  I think they are more 7B when they are small.  When trunked 10F is around their practical limit, when sized like mine 5F or so maybe.

I think the main factor in getting them to survive in a colder zone is planting in a microclimate. Against a foundation on a south facing wall can make a huge difference than being planted in a super exposed place in the garden. Overhead cover is very important. If planted as an understory palm under a mature pine tree for example would shield a palm and for arguments sake let’s say a half zone of hardiness in my opinion. A very cold winter could kill them regardless, look at what happened in Texas last year. Palmetto seemed to make it where other palms didn’t, but there were still some that died. I would have previously thought a palmetto would be bulletproof Dallas area and south. To the main point, planted out in the open in zone 7b seems like a matter of time until the cold gets it.

Yes, I really agree. My minors and my Louisiana in my south micro-habitat are about 2-3 times bigger than minors from the same source and age, grown in open or shaded areas of my yard.

In my 6b climate, I've thought that a courtyard micro-habitat in a downtown, would be the best try for a trunking palm.

BUT, on January 19th, 1994, central Kentucky had a nice 20 inch (.5 meter) blanket of snow. Above the blanket, it was -22f in Louisville, -27f in Frankfort, -36f in Shelbyville, -40 f/C unofficially in Henry county (all sites 400 to 800 feet ASL).

I didn't have any palms then!

I survived that. I was in high school and missed the whole week of school. Then I went to college in northern Wisconsin lol.
There were large Trachycarpus planted a few years after that at a car dealership or restaurant on the east end of Louisville that lasted a winter or two. I even planted a trachy that survived a mild winter and moved it to Texas but texas heat or saline city water was too much for it.

When did you plant that one and did you plant it from one of Plant Delights small sizes?

It was from PDN , and in a tiny pot about 8 years ago . It may not look it , but it is 7' to the tip of the tallest frond now .

      I am having trouble with differentiating between Sabal x brazoria and Sabal x texensis 'Brazoria' , can someone tell me what makes them different and how different they really are? (Or if they're the same?)

      Howdy y’all! I’m a palm grower in central Virginia and I’ve got a few ideas to put out there to the palm world.
      Firstly, with regard to zonation: I feel as though the usda hardiness zones need to be updated because as I’m sure some of y’all have noticed, there are plants and animals living and thriving in places they didn’t use too. For where I live near Charlottesville, Virginia, we haven’t reached a 7a temperature in the last 10-15 years at least, it’s been reliably 8a or above sometimes 8b or 9a some winters. Because of this, I’ve been able to grow palms and other tropical which have previously been a stranger to my area. For starters, I’ve had a red banana (Ensete maurelii) for 3 winters and it has had no protection and is supposedly a 9a plant. It has been acted like any other musabaju you might see in a cooler climate. Furthermore I have a Sabal palmetto that just breezed through a really nasty winter we had here with ZERO protection and little damage only to the tips. I’ve also had a Washingtonia robusta that I’ve had for 3 winters as well, 2 of those winters I’ve only had to cover it and protect it for only a few nights during February. This past winter was too gnarly for it being that we had a few nights in the upper teens so I did leave it covered, but it did really well overall. I have had for 3 years now a windmill palm which has never seen protection at all and it’s thriving. I’ve had a dozen or so Sabal seedlings in the ground for 4 or 5 years now and I’ve still got 7 of them. All those along with half a dozen sago palms which have survived 4 winters now. That’s just my own yard, in Charlottesville itself I’ve seen a ton of palmage! At the UVA campus there is an enormous southern live oak that’s been there for god knows how long, but it looks to be at least 50 years old. There’s a lot of musabaju bananas as well. One persons home I drive by frequently has a very large pindo palm, tons of sagos, windmills, needle palm, huge Sabal minors, and cannas and other smaller plants. I’ve seen a few windmills around town as well, one huge one and a few smaller ones. But I feel that the climate zones have shifted about to allow for a much wider verity of flora and fauna and I believe that it would be amazing too see some more palms and more exotic palms tried in central Virginia to spice things up a bit. Palmettos now should be better than marginal as should pintos and Mediterraneans.  In any case those are my thoughts on palms in the central Virginia region, please let me know if you have any experience with palms in this region and hardiness zone shifts and anything else pertaining to this conversation.

      Hello everyone, so I haven’t seen a lot of coverage of this nature defying experiment but some of the In n Out burger chain restaurants that are new to Colorado have installed the iconic crossed palm trees at some of their locations such as this one of Constitution Ave. in Colorado Springs (Zone 5b\6a). These Sabal palmettos appear to have large gauge pipe heating cables rapped around the trunk and close to the crown. I’m also told they have coiled heat cables in the ground around the roots. They are left completely out in the open, and appear to have been planted in October 2021 (which I think is a terrible time). I don’t know the specific minimum temperature they endured this past winter but I know it was in the single digits on multiple occasions. Our past winter here was extremely dry. We didn’t have any moisture whatsoever from September 2021 to almost January 1st, 2022.  
      Winters are cold here in Colorado! I hope that they were able to make the winter and maybe we could see some growth soon. I would guess the heat cables are kept on 24/7. When I put my hand on the cable it was very warm. The days in Colorado are very warm I don’t think that’s the problem it’s the constantly below freezing nightly winter temps that worry me, they look pretty bad after this past winter. I also know that the In n Out in Thornton (Northern suburb of Denver) also has Sabals planted. I’m curious if anyone has more information, and also what you guys have to say about this incredible sight in the Front Range of the Rocky Mountains Ha! Have a look, there’s also yuccas planted in the foreground nearby, my guess is Yucca faxoniana. Thanks guys

      So last weekend we did a trip to Avery Island, La to the jungle gardens tour at the tabasco factory.  It was really cool. We saw some amazing sabals and sabal minors everywhere! We also saw some really nice cycads that I have not seen in Louisiana before. Could y'all possibly identify the cycad? We also saw a HUGE Chinese fan palm. Was wondering if anyone else has been there before. Also just letting y'all know it's a great place for a weekend trip :)
