Hello Bernergrrl,
What kind of pitcher plants do you have that are flowering?
I can appreciate how cool it is as I have a Sarrencia
psittacina and I did not even think about it flowering on
me but it has just opened up and is the coolest deep red
velvety flower I have ever seen. Got images of it but will
have to put them up at some later date.

From what I have read in other forums and possibly in this one, regular mosses are frowned on in your bog as they MAY
smother the plant. I know this is true with Venus Fly Traps
as that happend to mine but on Sarrencia I am not sure.
If the moss you are talking about is sphagnum then don't worry about it as they grow together.

If you decide to get rid of your mosses and do not want to
replant them how about sending some to me!!! I like mosses
and grow mine in pots, beside having a sphagnum bog (which is currently dominated by sedges!!). Let me know-you can email me or post here. Whatever is cool. Thanks.

If your plants are doing well and the ph is low I wouldn't worry too much about the moss, it shouldn't alter the ph. If it gets to be too much just remove a bit.

Congrats on your first flowers!

Thank you for the replies. I'll post a picture of the mosses b/c I'm not sure it's sphagnum.

I think I have S.rubra--but can't remember--whatever survives Zone 5.

Thanks again!

Might your Sarracenias look like this?

This is an S. purpurea, which has the potential to live this far north.

And might your moss look like this?

This is long fibred sphagnum moss, as mentioned earlier and what is reccommended for carnivorous plants.
