Sabal Maritima hardiness


TexasColdHardyPalms

Recommended Posts

Anyone know if this one is more or less leaf hardy than Causarium or Dominguensis?  Right now Bermuda and Uresana appear to the be largest true zone 8 hardy sabals as my causarium/dominguensis keep burning every year.

It's less leaf hardy than both. It's fragile. It's seems to come back, but seems to get smoked every year. Similar to your experience with domingensis. Now causiarum is significantly more leaf hardy than these other two. Surprised to hear yours are getting burned every year. My causiarum had minor burn from last year's 15f. I have a causiarum/palmetto hybrid that's comparable to uresana. Love the silver uresana.

Bummer.  I am thinking the causarium are probably Dom's based in their leaf hardiness, but they womt seed so i cant tell for sure. The smaller seed grown causarium are hardier than the big trunking palms.  

Sabal Bermuda are very hardy but slower than molasses.

For us, of these five, uresana and causiarum are the only ones that are proving to be good picks. Their leaf hardiness allows them to gain mass without getting knocked back each year. Of course, palmetto, mexicana, minor are great for us. Riverside grows well, but it is so susceptible to scale.

There's a guy on here that periodically gathers hybrid seeds of a causiarum x palmetto palm from the University of Florida campus. With your operation, you should try to get a bunch of those. I have one by my pool. It acts like a real robust palmetto. Grows like gangbuster.

I actually have five of those palmetto/causarium hybrids in 3G containers and was looking forward to getting them in the ground and would love to get a source of seed for them as well.  We get scale on the Bermuda but the Riverside's don't seem to get it over here and grow very quickly.  

Do you have an Rosei or Pumos over there? I have a few Rosei that we are testing but they aren't quite as leaf hardy as Mexicana or Uresana, but appear to be more than hardy enough for us.

Maybe one day we'll have an uresana x causarium hybrid that'll prove to be a solid zone 8 texas giant fan palm.

Rosei and pumos have both been pansies. I'm sure you have a Tamaulipas by now. They're like the cooler cousin of Sabal minor. Mine is fruiting now. 

The causiarum X palmetto is probably gonna be a biggin'.

The silver uresana is probably my favourite Sabal.

Buffy,

Thanks for the link to the original thread.  How big is your causiarum x palmetto F2 that you grew from seed back in 2009?  I've got a few Sabal guatemalensis that I germinated in 2012 that have yet to go palmate after 5 years and still a bit smaller than a Sabal riverside that is only 2 years old from seed.  They're all in the ground now so hopefully this coming summer will encourage some speed.

Hi Jon: I kept mine in a 2 gallon pot for 5 years. I couldn't decide where to plant it. After about 6 years of nursing a Jubutygrus in a spot near the pool, I pulled it out. It just struggled with spotting and took too much damage with any stress. I replaced the Jubutygrus with the Palmetto/Causiarum hybrid. It was about two feet tall and semi palmate. Once in the planter, it has taken off. In four years it has about a 12 foot spread. Each frond is longer and more massive than the past one. It's gonna be a good one. Like I said, looks like a very robust palmetto. Doesn't show the characteristic leaf attributes of causiarum.

About how hardy do yall figure this palm is? What temps typically burn them? Sorry for the thread-jacking as I seem to have no forum etiquette...

LOWS 16/17 12F, 17/18 3F, 18/19 7F, 19/20 20F

Palms growing in my garden: Trachycarpus Fortunei, Chamaerops Humilis, Chamaerops Humilis var. Cerifera, Rhapidophyllum Hystrix, Sabal Palmetto

I'd guess serious damage south of 10F. But that all depends on whether it's hardened off. Lots of variable. But 10F is where I'd start to think of some solutions. Who knows on the seedlings.

That's awesome!  Sounds like a winner for you!  I'm assuming that it's in full sun.  I'm looking forward to seeing my Sabals gain some size.  I don't think I've kept any palm seedlings in containers for as long as my Sabals.  I lived in Tyler 2000-2002 which is pretty similar to Longview and I remember seeing 15ºF 2 or 3 times during my stay.  That's where I planted my very first palm...

I didn't realize they were so tender. Because it's planted under a live oak, this one has never been damaged that I can recall. I'm sure it would have been if it was in the open, based on y'all's testimony. Of course in a decade or two, it will grow into the tree, but maybe this property won't be my problem then anyway.
