Interesting question: why doesn't poison ivy run a drug ring being able to grow pot and coke on demand? hear me out i know plants are her babies but she regularly makes plants that get slice and diced in battle so she in my mind could see it as means to a ends sorta situation, getting enough money to support her plans or just getting money in general as i often think about poison ivy hypnotizing Bruce Wayne so her and Harley could go on a shopping spree with his wallet, and the Batman movie hush were she hypnotized cat-woman into bringing her a bag of money, so she's not fully above money in at least some versions, i'm just picturing breaking bad but breaking ivy with her being able to grow a whole shipment load of pot and coke easy within a couple of seconds have some goons quick cut it down and make off with it, never growing in the same spot twice becoming a millionaire in days.
