I've always grown mine in a bog garden - ie. water saturated soil. I'm
wondering if it is possible to grow them as a marginal - ie. the rhizome
is underwater.....I know it is a dumb question but I'm trying to
formulate ideas for this ever evolving pond project

Yes, that is where I grow mine and they are thriving.

I have one iris that has the rhizome submerged at one end of the pond in
about 4 inches of water. It's bloomed every year for the past three years
and is doing fine.
