From the simple, practical elegance of herb gardens that reflect the utilitarian needs of early settlers, to the ornate designs of the Victorian era, the charm of Colonial Revival sunken gardens, and the wild, natural beauty that inspired the Impressionist artists, Connecticut’s historic gardens offer a diverse and enriching experience that highlights the state’s vibrant heritage.
Be sure to take advantage of CHG’s Passport Program. At your first location, pick up a Connecticut’s Historic Gardens brochure, have it initialed at three member locations, and you’ll receive a free packet of notecards featuring the works of the CHG Day Poster Art Contest winners.
CHG’s mission is to cultivate a passion for the diversity of historic gardens at distinctive historic homes in Connecticut.
