We live in an age when the mapping of ecosystems has never been so precise, when every plant species is inventoried, tracked and geolocated. And yet, in the garden, on the street, in schools, who can still name what grows, climbs or crawls at their feet? If the environmental crisis is forcing us to rethink the way we build and live, it is also encouraging us to relearn how to see, and to maintain an active transmission of scientific knowledge between generations. This is not a return to idealized nature, but an adjustment. So that plants in the city are not just visible, but recognized.
