Well, this is going to be a newbie-ish question. I've been wondering if there is such a thing as'heirloom' carnivorous plant? I think heirloom is defined as a plant passing down through generations and before the 1950s when commercial hybridization took off. If Darwin wrote about CPs in 1875, then maybe some CP were passed down generations by collectors? Actually, how long can a CP of any kind live?
