The end result of the exhibition is a collage of plants in urban spaces, both fantasy and reality. We see drawings of a Plug-In-Vertical-Farm by Claude Boullevraye de Passille, and renderings of vertical gardens and villages by Naomi Reis and the Harrisons. Alongside them sit ceramic planters and a live growing wall. Some projects have been realized; some are pure thought experiments (a rendering of connecting urban rooftop gardens would require a few local codes to change — it includes urban rams). Disciplinary lines, as so often happens with culture and sustainability, are heavily blurred (one rooftop garden refers to itself as an ‘eco-art’ project).
The quality of plants invading varies drastically, as well: in some projects, the addition of a simple lawn to a roof provides sufficient green space. Other projects require low-maintenance, succulent, or air plants. Still others seek to make food production as local as possible. Plants get in, on, under and next to us, oxygen-producing neighbors. As a comprehensive exhibition, Vertical Gardens succeeds in giving a panoramic view of a very happy invasion.
