Has anyone ever attempted to cross the different genera within this family? Like Sarracenia × Heliamphora, Darlingtonia × Sarracenia, etc.? I've always wondered if something like D. californica × S. psittacina would be possible since they resemble each other so much, but it actually turns out they are only distantly related within the family according to the DNA cladogram on this page. Rather it looks like Heliamphora is a sister taxon to Sarracenia, so those two would probably be the best candidates. Such a combination would produce some crazy plants for sure.
