So I put in a bog garden last year which consists of a large hole dug out and lined with a pond liner and then filled with peat and play sand. It's right under a gutter downspout and is only watered with rain, but it stays wet because of the pond liner. It has standing water in it a couple days after a heavy rain, but otherwise it's just mucky.

It is a small area, just 4' by 3'. I had put pitcher plants and venus flytraps in it but the neighbors dog dug them all up and I really can't justify replacing them just to have them dug up again. So, I'm looking for a sturdier alternative. There are probably 4 pitchers left and then some sundew and a couple other natives I can't remember the name of.

Any ideas for what else might work in here without getting too large? Are rain lillies something that might like that sort of setup? Or does anyone here know of a source for any other native Florida bog plants?
