Living walls in the middle of a mural? That's a damn cool idea, but only if you’re ready to deal with all the weeds, bugs and bureaucracy that comes with it. Make it a real experiment, not a pretty postcard. The city will need permits, the artists will need a patch of green that actually stays green, and the whole thing has to survive traffic, rain, and the occasional vandal. If you can pull that off, it could turn a boring wall into a living debate piece—pretty sure people will start asking how many times a day a painting “reacts.” Just make sure the bio‑art doesn’t turn into a bio‑hazard.
