Many, if not most, of the Aponogetons available in the trade are 
hybrids.  They have been crossed to produce plants that are more 
tolerant of tank conditions, while still maintaining the "look" of 
the original species.  From what I've read, it seems that about 
60% of hybrid Aponos are self-fertile.

Inron in this form is not in a state useable by plants unless in a 
reducing environment. (anaerobic substrate)

As far as a nail poisoning someone, it's unlikely.  While you are 
correct that many childern each year are poisoned by getting into 
Mom's iron SUPPLEMENT, it is a well-known fact that you can 
usefully increase the iron levels in the foods your family eats by 
cooking them in cast iron pots and pans.  Stainless steel doesn't 
work, however ;-)
