This stuff is all over Miami. It is indigenous to the Florida Keys, not to NW Florida. I'd like to know more about the extraction process. I'm sure it will look lovely but like everything else we extract from the natural world I wonder if it is a benign process? Of course you could say the same thing about wood or concrete. Just saying, calling it "indigenous" doesn't necessarily mean it doesn't come at a cost. You pays your money and you takes your choice.
