Join members of The Garden Club of the Back Bay on Wednesday, January 13 beginning at 10:00 am at The College Club, 44 Commonwealth Avenue, for a January meeting featuring Chris Kurth of Siena Farms in Sudbury, Massachusetts.  Over the last 20 years, Community Supported Agriculture (CSA) has become a popular way for consumers to buy local, seasonal food directly from a farmer.  Here are the basics: a farmer offers a certain number of “shares” to the public.  Typically the share consists of a box of vegetables, but other farm products may be included.  Interested consumers purchase a share (a/k/a a “membership” or a “subscription”) and in return receive a box (bag, basket) of seasonal produce each week throughout the farming season.  This arrangements creates several rewards for both the farmer and the consumer, and Chris will detail how this grass roots movement has had a profound impact on how we eat.  Many of our members know Chris from The Farmer’s Market on Copley Square, where his beautiful produce is always in high demand.  He supplies a number of Boston’s best restaurants as well.  If you are a GCBB member, you will receive, or may already have received, a written notice of the meeting.  If not, please rsvp to info@bostonflora.com.  There is no charge for the meeting, but there will be an optional lunch at the Club following the talk, which will cost $20, and reservations are essential.
