I need a recommendation for some sort of grass that will be planted in a
shaded area that occasionally floods. By occasionally, I mean it never
flooded last year, this year maybe 5 times. We're not talking a little
standing water, we're talking three feet of turgid storm water that can take
a couple days to drain, leaving a thick mud layer behind. I'd love some sort
of ground cover that could withstand that, plus some foot traffic, and help
keep the area from being a muddy mess.

Any thoughts?
