Connecticut's Historic Gardens Day
June 23, 2024
12 noon to 4 pm

The Thankful Arnold House Museum is one of 16 Connecticut Historic Gardens which celebrate on Sunday, June 23, 2024.

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, hosts its annual CT’s Historic Gardens Day on Sunday, June 23, inviting visitors from Connecticut and beyond to experience the serenity and beauty of places that have charmed and inspired patrons for a century or more. Offering a variety of events and activities, CHG member gardens encourage visitors to explore a wide range of garden styles and periods, all within Connecticut’s borders.

Whether interested in 17th-century herb gardens, 19th- and early 20th-century estate gardens, simple or elaborate, functional or purely decorative gardens, visitors will learn something new and enjoy a lovely afternoon in a variety of historic settings. Each site has something special to offer the entire family, from live music to craft projects. Hours are noon to 4 pm unless otherwise noted. For details on each site’s activities, visit

Make a day of it! Visit gardens in your area, or plan a day trip to see a few farther afield. At your first location, pick up a brochure as part of the Passport Program; when you visit at least three gardens, collecting a stamp or initials in the “Passport” box at each, you’ll receive a special prize at your third garden visit.

Visitors will learn how herbs, vegetables, and plants were used by the Widow Thankful Arnold in the early 19th century. The Wilhelmina Ann Arnold Barnhart Memorial Garden features over 50 varieties of herbs including those used in cooking, dyeing, fragrance, and medicine.
