What are the most COLD HARDY Chamaedorea?

[Dwarf Fan]

Other than Radicalis (I already have that one) what are the next most Cold Hardy palms from the Chamaedorea genus?

C microspadix is one that gets mentioned a lot for cold hardiness, is trunking also.

I remember stumbling upon a thread about this topic on here, if I can find it I'll post a link

Thanks Dave! 🤙

I have had C. Metalica , C. Tepejelote ( single and clumping) , C. Microspadix , C. Sefritzi , C. Radicalis tree form all doing well outside for 20+ years . We have had near frost conditions occasionally here in So Cal inland valley.

My c. microspadix and c. radicalis have been completely coated in ice from freezing rain and have come through relatively unscathed. Have also seen mid/low teens unprotected and same situation

I had no idea they would survive that low of a temp! Good to know .

I also have c. cataractum recovering from the roots after this past winter's mid/low teens. It has been putting on new growth painfully slow tho. I suspect this winter may do it in

I have a clump of microspadix that survived 9 F last winter.  It died back close to the ground, but since I was gone so much the last year, I don't know if any of it is still old growth or all new growth.  Not as good to look at as it was a year ago, but the clump is clearly regrowing.  It is in a shady spot under deciduous trees about 100 feet from the house and 100 feet from a marsh.  Radicalis close to the house did better.  Both were unprotected.  I wasn't even in the same state when the cold happened, and the house was not being heated, so the microclimate effect was less than if it had been occupied at the time.
