Wild edible plants are a free source of vitamins, minerals and unusual tastes to city-bred palates. Keep in mind that not all wild plants are edible, and not all edible plants are pleasant to eat. At Wayne Grube, we’ll go for a hike to learn how to identify these items as they grow in the wild, their medicinal and edible purposes and historical folklore. Dress for the weather.
