Most of us go for a walk in the woods and don’t think that much about the plants we’re seeing. We just know that we’re in nature and call it good. But naturalists know that there is a whole world of plant knowledge to acquire, including local plants’ various uses as medicine and food. Participants in the Edible and Medicinal Plants workshop will find out just this kind of information, as well as local flora’s role in cultural history. The class will be held on August 24, 9–11 a.m., at Sonoma Valley Regional Park in Sonoma. It’s free but registration is required at tinyurl.com/5ffx8422.
