Connecticut’s Historic Gardens Day is June 28, 2026
Enjoy tours and activities at 16 distinctive historic sites & gardens statewide
STATEWIDE: Connecticut is home to a bounty of beautiful and unique gardens, many of them an integral part of historic landmarks dotted throughout the state. Connecticut’s Historic Gardens (CHG), a group of sixteen distinctive historic sites and gardens within Connecticut’s borders, hosts its annual CT’s Historic Gardens Day on Sunday, June 28, inviting visitors to experience the timeless beauty and rich histories of places that have delighted and inspired patrons for a century or more. With a variety of tours and special activities planned, CHG member gardens entice explorers of any age, or those simply seeking a peaceful retreat, to take part in this special day. Hours are varied at each site so check for times and activities at https://cthistoricgardens.org/chg-day.
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 CT’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.
