The story on these things goes back a long ways. I made them, originally, for my previous campaign. More than 15 years ago, I saw these seed pods on the ground while walking my mom's dog. So I went back and gathered up some especially nice looking ones.
Then I trimmed them, mounted them, and carefully painted them. I left some the original color, and painted others purple and others a sickly green, with the "mouths" limned pink.
They're very tricky to store - they break, they've had to be hand-mounted with glue and held in place, and they're not small. I'm not sure if I'll keep them or not. I may, and then just discard them when I eventually move to a smaller place. But they've served the purpose I built them for years and years ago.
Their stats were a mix of my own, and a bit of Charles Saeger's. You'll see more plants that have his fingerprints on it, in mini (perhaps) and in combat (for sure) before the PCs
