There is one variety of H. polysperma that I read somewhere is not known to
flower, but the other Hyrogphilas often flower when emersed if they get
decent light.  Roughly two years ago I remember seeing an article in FAMA
(Freshwater and Marine Aquarium) claiming that emersed plants in an
aquarium had greater powers of nutrient extraction than submersed plants,
and, with a good growth of well-lit emersed plants, you wouldn't have any
algae problems.  There might be something to that claim, because emersed
plants have access to the atmosphere for CO2, and this can give them a
growth advantage over submersed plants.

Since I gave you all this priceless information, how about a good deal on
an upgrade to Filemaler Pro!  :-)
