Jean Everett, a senior biology instructor at the College of Charleston, says we all should know that this Palmetto State tinsel is neither Spanish nor moss, but is a bromeliad, related to the pineapple, and appears primarily in the coastal plains.

And there is a moss line, if you will, that runs across the state, roughly along the sand hills which represent a former coastline.
