Mine has been in the ground since 2021. Got it from Steve Anderson (Florida, I believe). You can see the growth charts below with the y-axis in inches of top frond height. I believe the Miamiensis has gone unprotected the past 5 years and, as a result, it regularly experiences temps in the low teens. I haven't had any problems with it. Zero care.

Is that a valid name?

For the first time in over 35 years mine froze last winter when it got down to 23 degrees here in St. Augustine. It surprised me because it killed them all the way to the ground. They are starting to sprout from the ground now fortunately but some of them were over 10' tall. It is so sad to see those full clumps of palms dead.

Sabal blackburniana?

What's your experience with Ravenea glauca seedlings? Mine isn't moving at all despite being outdoors in perfect conditions. In bright shade, very light medium, temperatures from 15 to 30 C, humidity around 50%, I water every other day.. all other palm seedlings are growing, like my Chambeyronia macrocarpa, my Kentiopsis oliviformis etc, only my R. glauca is not doing anything. Are they really that slow?

@RiverCityRichard I have 20+ C. radicalis I grew from seed from non-trunking parents and another couple I purchased that might have a little C. oreophila mixed in. They vary a bit in how stout they are at the base and how delicate the leaflets are despite all growing in roughly the same conditions. These appear to be growing more of a trunk than mine, but otherwise fall within the variation I see. If others have different thoughts, I'm curious to know as that is impressive cold hardiness and would be viable for my climate here.

Sold out could order more if interest

Thank you sir 1 left

I have Radicalis (non trunking form) planted beside it. Is healthy, but has not grown much over 3 years. The leaflets look similar, but this palm has more relaxed and thin leaflets

@sonoranfans probably a bit more of 3ft from costa to tip of leave. 30 leaflet each side

Definitive ID of most sabals is done through inflorescences. They are tough or impossible to ID when young. I would rule out sabal palmetto, petioles are too rounded on the back in cross section. How big is the leaf? Looks pretty big.

The terpene that gives pepper its odor is beta caryophyllene. There are limited studies on cycads since cycads are not an important source of beta caryophyllene for fragrance companies. It is reputed to attract some pollinators and it deters herbivores, which might be important to species survival being it comes from the cone. Macrozamia sp have been found to emit beta caryophyllene and other terpenes from the cones. https://pubmed.ncbi.nlm.nih.gov/17916726/ In the case of Macrozamia there is an odor mediated a push/pull pollination that is controlled by beta caryophyllene, beta myrcene, and beta ocimene. Most of what I have read about beta caryophyllene is its a herbivore deterrent, it tastes bitter to grazing animals and attracts some herbivore insect predators. As pure compounds, the beta myrcene smells of mangoes, and the beta ocimene is tropical/citrusy and is high in sweet basil plants. Beta ocimene and beta myrcene are some of the most potent attractors of pollinators but also repellents and even toxins of herbivore insects. For example beta ocimene kills aphids on contact very effectively, it doesn't just repel, it kills. I once bought a natural insecticide from the big box store and sure enough, the actives were a terpene mix including beta ocimene and others. I had a bad aphid attack when I lived in Alameda, it worked like a charm, all dead in minutes. ANd it smelled wonderful to me as I knew the fragrance was harmless and even healthy for humans. Here is one natural product pesticide/repellent you can trust(attached), always read the contents for what they are putting in it. This one has rosemary oil and clove oil in a water based suspension. Essential oils carry a number of terpenes unique to the species of plant. If you want to see all the terpenes you will have to look up assays of clove oil(mostly eugenol, very potent insect killer/repellent) and rosemary oil( a complex mix of terpenes)_ as they are natural products. Natural products don't have assays of all the contents (in a natural oil) on the label. Since humans consume both in spices on food, they are quite safe. Systemica_Indoor_Quart_R25-1.pdf

Looks near identical to my C. radicalis. I assume those were just two separate seedlings grown together.

For sure it ain't costaricana, because it lacks the auricles at the leaf base of new fronds.

Bought this as Chamaedorea CostaRicana last year as a small 1g. It’s going through its second summer and has been a pretty fast grower. It came from Redland Nursery in Homestead, where there is a lot of open pollination and many species of Chamaedorea in close proximity. Keep hearing that CostaRicana hates Florida, but this guy seems happy. Can anyone verify that is indeed what it is? Also should note it went through 24f with 30-40mph winds in February and was unscathed.

Perhaps multifrondis or debate sis? Encephalartos natalensis × horridus male flushing. I never removed last year's cones on this boy. It is developing a sizeable caudex with no pups. I have another on the other side of the Aloidendron Hercules, but it has put out a few pups in the last several years. This is a fast grower.

We have a saying in Greek like wish I had previously the recently obtained knowledge. That fits also in present case. Never miss taking pictures of the mother Sabal specimen, which you had gathered seeds from, focusing especially on reproductive organs, that is inflorescences. The more perspectives you use for the shots and the more close ups, the more will be the chances of a positive identification of both parent and offspring, provided that neither of them is actually a hybrid.😵‍💫 Otherwise you would have to wait about 20 years since germination for the offspring to reach maturity. All I can tell from those pictures is, that palman makes up around the half of the blade. This feature could exclude several spp.

Interesting. I've got more RPS seed on the way. I think this year I'll try a few different germination methods, including direct sowing some outside to see if our heat will get them going. I have no idea how old the seed is though, might have short viability.

Hello, I’d like to move this Copernicia Baileyana. It’s just going to be too big for the area and it’s too close to the Copernicia Macroglossa, which is better suited for that spot. I was wondering what the best way to dig this would be. It’s approaching 6’ tall, and maybe has a 9” base. Was thinking about digging in thirds (Fall 2026/Winter2026/Spring 2027) and putting it in a 25 gallon with some pumice to re-root. Or, perhaps replanting in the ground, that same spring? It’s in Clay soil. Anyone have experience with this? Thanks

Yep , great SoCal palm . This size is perfect for planting out . Mine grew from a strap leaf to a large palm in just over 20 years . This size will save a lot of years! Harry

I sometimes push seeds I find in other potted plants , just because I don’t want to throw them away or deal with them immediately. The problem is that I rarely know what I may have popping up . Yesterday I noticed something I couldn’t recognize . I was trimming some plants and pulling little weeds out of the garden when I saw something in a potted Radicalis over by the spa. Unlike anything seen before in my garden. I will know soon enough whe the first leaf emerges. It is very robust and dark in color . I do remember tossing around some Arenga seeds from our Engleri , maybe one got pushed into this pot while my mind was on something else? Harry I occasionally push seeds I’ve picked up in my garden in other potted palms . The only thing is , this one looks very different in size and color . I am hoping it is an Arenga mixed in with a few C. Radicalis . Whatever it is , it has a found a home! You can see the “heal” of a larger Chamaedorea Radicalis along with other babies. (That large root thingy).

Here is a result from a question to ChatGTP via Duck Duck go :

Great to see this post revived . I knew nothing about these until I saw one in Ventura at Terry and Sevin Sullivan’s place . It towers over the garden with a dominance like royalty . I didn’t know it was heat sensitive but it seems to like the coastal Ventura climate. Harry

A very beautiful palm and one of only a couple of Licuala that will grow here in our climate , in the right micro climate . I will be planting one as soon as I get my hands on it. I have a nice spot picked out for it. I will not be able to get one super large in my lifetime , so it won’t need much room. Harry
