There are probably a couple or five different at Modthesims (downtime at the moment), just search for "plantsim" and go to mods/hacks.
There is also a
plantsim potion (and also a de-plant potion) at parsimonious.
You can also change a sim to plantsim using the Insim mod (unsupported), and probably also the sim blender from
Simbology (but I'm not entirely sure of that)
Lots of choices - these are just a few of them
