Cattails are probably the best wetland plant for water purification,
used as such in John Todd's Living Machines
http://www.oceanarks.org) and some progressive sewage treatment
facilities in the US.
They are also an excellent and tasty edible (roots, young shoots,
and green seed head) and probably the best feedstock for ethanol
production there is, yielding 1500 gallons of ethanol per acre with no
fertilizer, pesticides, or herbicides, and over 2500 gallons an acre
with the added nutrients from a sewage plant. See David Blume's
fantastic book "Alcohol Can Be A Gas" (http://www.permaculture.com).
