@evan another example is this (the Darlingtonia Californica): https://plants.ces.ncsu.edu/plants/darlingtonia-californica/
which honestly- is beautiful, interesting and not at all suited to be a houseplant. The natural habitat range is small and getting smaller over time from climate change, land development and poaching.
However, they are greenhouse grown here in Germany and ethically-sourced. But to keep them alive when you get them home takes extra effort and energy (including 0/low TDS water) so they do not die right away.
