I went down a rabbit hole and found this: a crowdsourced map of every apple tree, berry bush, and herb patch growing on public land — mapped by foragers all over the world. You type in your city and suddenly you know where the mulberries ripen in June and whose sidewalk has a rosemary bush spilling over the fence. It feels like a secret layer of the city was hiding in plain sight. I'm already planning a walking route past three plum trees I never knew existed. What's growing near you?
