That was interesting but another page, about how tree ferns can soak up 
arsenic from contaminated land, was too. I was amused by the statement:

" ... ferns clean up contaminated soil by a process called
phytoremediation. 
A contaminant -- like arsenic -- is absorbed through the plant's roots.
The 
arsenic then moves up to the leaves where it's stored. The leaves can then

be cut off. "

And then what? How do you dispose safely of the leaves??
