Herbs, those mystical, magical, wild, exotic plants from around the world have been the currency of kings, the pharmacy of healers and the delight of cooks from the dawn of time. The Gwinnett Environmental & Heritage Center is introducing the More Herbs, Less Salt program at McDaniel Farm on Aug. 18 and Aug. 25 to learn more about these valuable plants. “Late summer is a great time to focus on garden herbs as they are at their peak for harvest,” said Catherine Long, history and culture program manager for the GEHC. “If you have not had a chance to visit the heritage herb garden at McDaniel Farm, the More Herbs, Less Salt program will allow you to explore this local treasure.”
