Rooftops covered with plants go back hundreds, if not thousands, of years. In China there is the roof iris, Iris tectorum, so named because it flourishes on sod. In Northern France and England there is an old rural tradition of growing moss, ferns, and hens-and-chicks (or live-forevers) on the roofs of houses, covered entryways, and out-buildings.
I am delighted to report that the art of garden-making is alive and well in Springs. You can see for yourselves on Saturday on the Animal Rescue Fund’s annual garden tour, which features five gardens in that hamlet (plus one in Amagansett).
