The Boston Natural Areas Network will hold its 8th Annual Harvest Festival & Perennial Divide on Saturday, September 13, from 10 – 2 at City Natives, 30 Edgewater Drive in Mattapan. Bring plants to swap and containers to carry them home. You’re invited to exchange, donate or simply take home plants. Shop for hard-to-find native plants, fall gardening supplies, soil amendments, cover crop and season extension supplies, and enjoy the harvest season with fellow gardeners.
