Chambeyronia triples in pot?

[Adam_NY]

I'm thinking about adding a Chambeyronia to my collection and got to wondering whether it might be a good idea to do triples in a pot.  Would there be any issue with putting three of this type (either macrocarpa or hookeri) in a single pot?  I would start with 2-3 footers shipped bareroot.  How would I best pot them up so they grow a graceful curve over time (close together straight up, close together angled slightly, a few inches away from each other)?

Also, I'm in downstate NY so these will be outside in shade/filtered light in the warm months (summer can be quite subtropical) and winter protected in the cold months.  Would these be happier during the winter in the house (gets relatively dry from the radiator heat) or in the greenhouse?  The greenhouse stays relatively humid compared to indoors, but I only heat it to around 40 degrees, so there would be several months where nighttime lows get down to 40 and day time ranges anywhere from 40s to 70s depending on how sunny it is.  My Chamaerops and Phoenix roebellini do fine with the cold greenhouse and basically stop growing, but maybe Chambeyronia wouldn't be happy with that setup.

I admit I'm no fan of jamming multiple solitary palms into pots but I've never heard of that done with Chambeyronias. I'm not sure that's a great idea because: 1) Chambeys get quite large and their red spears may shoot up many feet above the crowns before opening, 2) they have quite large, leathery leaves that arch and droop, 3) you would need one heck of a huge, wide pot to contain them and a forklift to move them indoors for winter, 4) they could fill up a room easily when they get big, 5) unless you have 16'+ ceilings in a conservatory you will be unable to provide them all the light and warmth they will need to get through your winters. These are 9b palms at best. Also, I have grown both macrocarpa and Hookeri and have found Hookeri to be far less robust. A Hookeri teamed up with macrocarpas would soon be outcompeted and snuffed out. And, frankly, palms this gorgeous should be appreciated on their own solitary merits. On the other hand, I've been assuming yours will actually achieve the kind of dimensions I mentioned, which they may not in NY.

I have a couple in the ground, and basically agree with everything that Meg said, because they get so big.

But they are going to be bonsaied in a pot and with that cold too, so I would love to see the results of you trying it .

They do have big leathery leaves but not many of them, they may intermingle well, and they will not be fast, that is good.

Yes give it a shot, I reckon they will keep you entertained and happy for years.
