Sunday, May 5, marks the start of Berkshire Botanical Garden’s 90th outdoor season and the annual Roy Boutard Day, a community celebration steeped in history and tradition that honors one of BBG’s most influential past directors.  Admission to the Garden is free all day. Visitors can stroll the 24-acre grounds, enjoy the spring blooming bulbs and trees, visit the Visitor Center Gift Shop, and attend the Horticulture Certificate Program graduation, followed by a reception hosted by the Herb Associates, a volunteer group that, for 65 years, has created herbal products from the Garden’s 1937 herb garden. Members of the Herb Associates will serve an assortment of herb-infused cookies and Mai Bowle, a May wine punch. The day also includes activities for children.
