Beneath Andernach's medieval city walls, birds flit among apple, pear and peach trees. Strawberry plants and heads of lettuce sprout from the soil alongside patches of herbs and wildflowers. It's also home to the highest cold-water geyser in the world, a big tourist draw. But today, visitors have another reason to come to Andernach its city gardens. "If you feel like picking something for dinner, feel free," said Anneli Karlsson, the project coordinator of the Edible Cities Network in Andernach. "That's our motto: Feel free to pick." Andernach, with a population of around 30,000 people, is known as an "edible city." Its public green spaces are used to grow food that anyone can harvest free of charge. The city's administration launched the project in 2010. The idea was to get locals more engaged in their community and raise awareness about how food is grown. No pesticides are used, so the produce is all organic. But Andernach's gardens aren't just about food. Karlsson said the project is unique because it hires unemployed people to maintain the plant beds, alongside a team of gardeners. "It has changed my life," said Jörn Schamari, a former truck driver. He suffered burnout and was out of work when he came across the edible city initiative several years ago. "This project helped me bounce back. And from next year, I've been promised a permanent position as a gardener here. The project has also changed my relationship to plants."
