The Mayor’s Rose Garden Party is an annual fundraiser which benefits year-round programs in City of Boston parks and allows thousands of children and families to enjoy arts, science, and fitness programs as well as special events in their neighborhoods. Now in its 19th year, the annual Rose Garden Party has become one of Boston’s signature events. The party takes place in the Kelleher Rose Garden in the Back Bay Fens, when 3,000 rose bushes are at peak bloom. There will be passed hors d’oeuvre, buffet, and complimentary libations, plus live entertainment and a spirited creative hat contest in a garden-party setting; live and silent auction, en plein air painting demonstration and a Hollywood red carpet experience with a Step and Repeat backdrop courtesy of StepandRepeat.com. Proceeds from the ticketed event directly fund free programming in neighborhood parks throughout the city. Tickets are $150 and may be purchased online at http://www.cityofboston.gov/parks/rosegarden/rosegardenparty.asp.
