Seen this fern in several spots in Venice. Always near water, in mangrove thickets. Up to about 8' tall (sporing fronds). It's a pretty impressive plant (I'm not normally into ferns...). How tolerant of cold, drier conditions? Could it grow in SoCal too with water?

SoCal and SoFla; zone varies by location.

Appears to be a leatherfern (Acrostichum sp.). Either A. aureum or danaeifolium.  I believe danaeifolium is more common and cold hardy.  I have wanted to try this at my place as well. Just need to find the right spot in the yard.  They take lots of water from what I have read.

Thanks. Will look up the differences between those two spp.

Acrostichum danaeiifolium is more common. I even see it inland and have seen it by springs even north of Orlando. I have never seen A. aureum inland around here.

Don't even try it if you can give it plenty of water daily. I've killed a couple that way. Finally placed one right in front of one of my sprinkler heads and it's doing fine. They're amazing to see in nature here in FL (Naples: Corkscrew Swamp Sanctuary, Freedom Park). They get literally MASSIVE!! So prehistoric looking :wub:

Naples (inland), FL - technically 10a but more like 9b in the winter :hmm:

How cold hardy is A. danaeifolium? At what temperature do the fronds show damage? What is the killing temperature?

Around 28F will damage the fronds. low 20sF will kill it.

And it does need LOTS of water. Either growing in water or in wet boggy soil. I have tried it quite a few times in our well drained sandy soil with heavy mulch and good irrigation and it dies. Even more dry sensitive than Cyathea cooperi.

Thanks all for the info. I think will skip trying in SoCal...

I may give it a try here in Austin. Pretty sure I can keep it wet enough in a somewhat shady spot with our deep clay soils.  More concerned about the occasional cold spell.
