Hi I bought these seeds Does anyone have experience growing ceroxylon palms in California I’m in the antelope valley ca and it gets low 20s to sometimes 115 degrees but this year hasn’t passed 106 i have a microclimate with a pool and a place that has lots of shade I heard these palms hate heat But are very cold hardy to 17 degrees and any tips on germinating these seeds also if u have any recommendations for crownshafted palms

The only people that I know of that might be growing Ceroxylon are @Darold Petty and @Jim in Los Altos but I don't know if they have experience growing them from seed.  Ceroxylon do best with cool night temperatures and they wouldn't stand a chance in this part of the world, unfortunately.

The nights here go really low to 60-70 in the summer then in the day it goes to 100s but unfortunately I don’t think I can refund the seeds 😞 so I’m gonna experiment

That's how we learn. It's all an experiment, really.

  Welcome to Palmtalk !   

"The nights here go really low to 60-70 in the summer. "

  This is warmer than my daytime high temperatures.  Ceroxylon requires a sharp differential between the day/night temperatures.  Low temperature tolerance of 17 F is plainly, just wrong.  Cloud forest conditions in Colombia and Ecuador are mild daytime and lower nighttime temps with always high humidity but never actual frost.  This is not the case with Lancaster.   I would never suggest Ceroxylon in California unless the site is close enough to the ocean to experience the marine influence.

However, no one will learn anything new by sticking with the conventional wisdom, so give it a try and keep us informed.

 

@Darold Petty Okay thank u I’m gonna try to grow them since I don’t have any choice I can’t refund so but do u have any germination tips I’m gonna try to grow them in full shade near my pool to many create some sort of microclimate will the jubeaopsis palm do well and do u have any recommendations for crownshafted palms in zone 9a

Try Dypsis decipiens,  very slow to start, but can take sun and some frost.    There are others on this forum closer to you who can offer better advice. 

I tried 3/4 species of Ceroxylon, they all died in our long Mediterranean summer

My only 'success' with Ceroxylon species involved sprouting seeds of the uncommon C. sasaimae and growing them for a couple of years in tree pots until it was obvious they wouldn't tolerate our sweltering Sacramento summers much longer. I donated them to the San Francisco Botanical Garden at Strybing Arboretum. I hope they'll be able to plant them out in a few years. Regardless they may be enjoyed by visitors there for many years to come. Right now I have a C. amazonicum tented in plastic because I wanted to try one more time a species that presumably can take more heat. 😉

That’s an ambitious undertaking. Based on the climate chart below, you’re in a very hot summer desert-like climate area. I’m afraid way too hot and dry for any of the Ceroxylon species since they prefer a cool coastal climate. San Francisco is ideal. I’m in a warmer valley to the south of SF but well within the tolerances of Ceroxylon since summer highs are mostly 70s-80s with nights in the upper 50s and my three Ceroxylon have done well for years. Humidity levels are high here too. 88% right now at 12:45 am. Ceroxylon need some humidity since they are cloud forest palms. 
 

Jubaeopsis caffra will handle a lot of heat. Young ones cannot handle repeated freezing weather though. Even large nature ones can only handle freezing down to the lower to mid 20s if it happens just once in any winter. Their very slow growth means freeze damaged fronds won’t be replaced no one growing season. 
 

Have you researched other palm species better suited to your climate? There are many. Brahea armata, B. edulis, Chamaerops humilis, Butia odorata, and the Phoenix genus for starters. 
 

@Jim in Los Altoshi unfortunately I can’t refund the seeds should I experiment and I’ve been trying to look for crown shafted zone 9a Cold hardy palms that’s why i picked ceroxylon I also been trying to find dyspis decipens online but I have no luck also acrocomia totai  but what im gonna do with the ceroxylon is maybe grow them very close to my pool in full shade so maybe it will get the affect of the humidity and hopefully it stays cool in the shade 

@Jim in Los Altos here is the temperature for the week today was 104 the humidity will be in the 30s

@HillizardHi unfortunately I can’t refund the ceroxylon palm seeds 😞 but I’m gonna try in full shade once they sprout or bring them in summer and put them out in winter hopefully they can somehow adapt 

@gyuseppewow have u tried in full shade maybe ill try in full shade near my pool or bring them in my house for summer and take them out for winter unfortunately i can’t refund the seeds

yes they were made from seed and I had placed them in the shade under other palm trees, they didn't get any sun, but even in the shade here in summer it's very hot

@gyuseppemaybe im gonna put it near my walls of my house which are cool and a shade cloth covering it

Your reasoning is correct, but we need to see how much the air temperature is, I don't know your area, but here in southern Italy, in the summer we have heat waves that come from the north Africa, so wherever you go you sweat alone without doing anything.
