What Are These Called Again?

[PalmTreeDude]

I know this is a common tropical (cold hardy?) looking plant, I remeber seeing them on Hilton Head Island, SC, but I completely forgot what it was called and there was no tag on it (In Phipps Conservatory in Pittsburgh, PA). What are these called again? How hardy are they?

Thank you.

This has a new name .

Thaumatophyllum bipinnatifidum

They are solid 9A plants . If mulched or given a little extra protection can probably survive in 8B

That explains why I only saw them around Charleston and Hilton Head. They had some big ones though.

Yes, definitely a 9A and even warm 8B plant. Here are a few in my area in the NW Florida.  3-5 feet of trunk on all of them.

Mine burn pretty bad around 25F, but recover quickly in the spring.  That's with no protection or canopy.

Believe it or not but these will grow here in the Desert, provided shifting / bright shade a an hour or two past sunrise,  until sundown.   Wouldn't be surprised to see them reach large size under the canopy of a grove of large Texas Ebony or Mesquites,  esp. if that spot is one where runoff can collect when it rains during the summer.
