An evening guided walk around Harpenden Common, looking at how to identify the wildflowers of the common and what uses some of them have in traditional medicines. What can nettles do for your arthritis? What uses are there for sticky weed? This walk is an opportunity to dip your toes into the world of herbal medicine and is not run by an expert herbalist, but will offer an educational walk learning about wildflowers, with a twist. Suitable for all but the walk will take place across Harpenden Common, with some rough terrain and will cover about a mile. This event is free, but booking is required.
