I was looking the plant up and realized that their territory was the eastern United States. That would imply that the native nations would be aware of them. Was there any special interest towards the carnivorous plant, or were they just another little swampland novelty?
Various Siouan bands including the Cheraw, Chicora, and Waccamaw of what is now coastal North Carolina were known to have used this and other plant species as part of traditional herbal healing. Many cultures from every corner of the globe from time immemorial to the current day both self-treat and/or have some version of a "medicine man" who collects plants, animals, and minerals to both treat and prevent physical as well as spiritual (curses etc...) disease. The VFT held no special place above and beyond the myriad of other natural cures traditionally practiced by the various native tribes. On the other hand the writings of Peter Martyr D'Anghera, "DE ORBE NOVO", in the sixteenth century (written in latin) do seem to perhaps depict the ritual use of this plant.
In the biological classification system indigenous to the Southeast the major categories of life, there's a major category for humans, four-footed mammals, birds, below-world animals (a category that combines what the Linnean systems would call reptiles, amphibians, and fish), and plants. The various invertebrates were sometimes placed in their own category and sometimes included as a subdivision of below-world animals.
These categories, however, were recognized as imperfect and that various species bridged the taxa. The liminality of these species invested them with special cultural significance and power. These included species like bears (between the Two-Footed humans and the Four-Footed animals) and bats (between the Four-Footed animals and birds). Carnivorous plants, the flytrap and the pitcher plants, were seen as linking plants to humans or to predatory animals.
The flytrap's liminal position made it particularly potent in hunting medicine. The Cherokee would trade for yugwilu, (depending on the context, could refer to the flytrap or the pitcher plant, or the roots of either) even after the Removal. It was particularly favored by fishermen because a small bit of yugwilu (presumably the flytrap in this instance) would augment the bait, employing the liminal power of the flytrap to attract a fish and prevent it from slipping off the hook. The water from a pitcher plant aided in memory.
