Dwell magazine has a great article about San Franciscans’ digging up their sidewalks and planting gardens. Much of the credit is due to Jane Martin and her organization Plant*SF, which has helped neighbors and corporations turn concrete into habitat for plants, wildlife and community.
Martin estimates that 15,000 square feet of pavement have been replaced by public sidewalk gardens that absorb rainwater and require no irrigation. I like how Martin describes her test for native plants: “I’m an Iowa girl, so I learned about natives by planting stuff and leaving town. Whatever was alive when I returned passed the test.”
Compared to San Francisco, Tokyo’s climate, with almost year-round rain, offers an even greater potential for plant life in public spaces with minimal care. With so many avid gardeners growing such a variety of plants in small pots, I can only imagine how much more impact they would have if they received government or nonprofit help to dig up the concrete and plant directly in the earth.
