Acrocomia (previously Gastrococus) crispa

[Austinpalm 238]

I've seen this palm listed as a zone 10a palm. Other Acrocomia have proven to be hardy to at least 9a with occassional reports of hardiness to the upper teens (8b). Has anybody had an experience with A. crispa surviving zone 9a temperatures or cooler? I have seen some seeds for sell and am curious if there is even a chance of growing it here.

On a side note. An A. mexicana I have planted appears to have survived 16F with significant damage. It is putting on new growth though.

My 3 foot specimen was undamaged from this past brutal winter. From this, I can tell it can take 25 F (minimum at my house last last winter) without damage, and it can tolerate prolonged cold nights and chilly/cool days without damage or rotting.
