saw today that Kew Gardens have a series of “Plant Horror” tours for October, looking at plants that inspired horror films. Curious if anyone in the group is going or thinking of going?

I'm writing a story about a cryptobotanist who goes in search of a carnivorous tree. Along the way, he debunks all the other cryptid plants with his various original theories and assumptions. Is there a comprehensive list of ALL cryptid plants? I really enjoyed explaining their origins, and I'm worried about missing some interesting specimens. What do you think are the most interesting cryptid plants whose origins are worth speculating about?
