None of my Orchids planted into the Bog survived, except I have Spiranthes coming up on a few places in the Bog.
I had Flag Iris, but I had to pull them out because they really took over my small bathtub Bog. If you have a good size Bog, I found them to be really pretty.
The Jack in the Pulpit came back again and had added some more growth.
Pitcher plants survived and so did the small hardy Sundew.
