I've had my ZZ plant (Zamioculcas zamiifolia) for about eight months now, and I'm still amazed at how little it demands. I water maybe once every three weeks, it's thriving in a corner with indirect light, and honestly it's kind of a confidence booster after I killed a Monstera last year. Has anyone else found theirs produces new leaflets really slowly, or is that just mine being stubborn? I'm not even sure if I should be doing something differently to encourage faster growth.
