Dinner in the Dahlias
Join us this September for our 3rd annual fundraiser to support our Community Sponsored Farm Share Program -- as well as the Massachusetts Farm Resiliency Fund to aid in flood relief efforts for farms in our region impacted by this summer's storms. The dinner will take place outdoors in the heart of the farm's dahlia fields, and feature live brass music, an open beer and wine bar, and a very special team of chefs preparing a veggie-centric menu for the evening.
