The article actually is about botany, but the title reminded me there is a whole area that could be called "criminal botany". As in, there are specific plants cultivated for illegal purposes. And on the other side, forensic botany (things like analysing pollen traces)
There's also guerilla gardening, where you plant stuff where you're not supposed to, typically municipal soil
Most plant–related crimes are pie–on–the–windowsill–on–Sunday tier.
There are a lot more to Criminal Botany. There's the chaotic evil variety, like planting an invasive species, planting bamboo near your enemy's house, and sprinkling mint on someone's garden plot. There's the chaotic good variety, like broadcasting native seeds on a grass lawn and releasing moles onto a golf field. There's chaotic neutral, like making air layering on trees that you don't own, or otherwise taking seeds, cuttings, or plantlets from them.
