Venus flytraps can't turn into a different form.
It just means that it is getting sufficient sun.

i'm saying they were mislabeled. I know that typical flytraps often get red on the inside, but the entire plant is turning red.

They probally planted a wrong batch of seeds,

I guess I'm lucky that Target's ineptitude didn't lead to the death of my plants.

Actually, they were growing in a drainless medium, and had that bad decorative moss growing around them. I don't actually know the name of it, but it's the thin green kind that shoots up about a half inch. Definitely not sphagnum.

They green stuff is likley the typical moss I always find growing everywhere I go.

They might or might not be mislabelled Red Dragons. The thing is that even among the typical form of Venus Flytraps, there is a lot of genetic variability. If the plants do change to all red, including part of the rhizome, they are likely Red Dragons or typicals that have strong genes for cultivating Red Dragons over several generations. In any case, My own Flytraps have that potential even though they are not all red. They produce red coloration not only on the inside of their traps, but the outside as well, and sometimes a trace of red on their petioles too. The rhizome has shown a streak or two of red as well.
