greetings, i'm actually considering keeping a boggy area
in my yard as well, and have been researching your
exact conditions

maby water forget-me-nots

bog sage

lobelia cardinalis, thats doing GREAT for me in a very wet condition, but i think too much shade, so i plan to move
it come spring

rain lilly

oxblood lilly

joe pye weed

.........sorry, i could go on, and on

those are some of the things i'm looking at for my area,
but i've got a shady area too and i'm looking at some ferns
that can take boggy conditions for most of the year

keep us posted!!

Ooh---what ferns will do well in those conditions? I do have some deep shade under the cypress tree.
