An Outstanding Opportunity to Visit 5 Beautiful Gardens
Sunday, September 7
10 am- 4 pm
The day features self-guided tours of 4 private gardens and Hollister House Garden.

The Sumacs
Washington, CT
The Sumacs features a stately home designed by Ehrick Rossiter and built in 1894. Rock outcroppings, specimen trees, boxwood hedges and gardens surround the house. A
formal potager enclosed by a hedge of yews, a cutting garden, orchard, and perennial gardens make an elegant nod to the classic English garden. Fall is ushered in with a colorful dahlia collection. A hidden woodland trail includes an array of specimen trees, shrubs, and shade-loving perennials.
23 Ferry Bridge Road Washington

Platt House
Washington, CT
The completely organic gardens surrounding the 1898 Rossiter-designed Senator Orville Platt House are an explosion of Dahlia exuberance and color in September. The original Rossiter retaining wall is the foundation for the upper-level veranda garden. A Purple Fountain Weeping Beech is the focal point of the top garden and 1000+ dahlias of approximately 75 varieties are planted throughout the property. The kitchen garden, wisteria pergola and a meditation house are of particular interest.
37 Ferry Bridge Road Washington

Treetops
Washington Depot, CT
This is an eight-acre property that boasts breathtaking views of Steep Rock Summit and south to Roxbury. In 2024, a complete reimagination of the landscape was undertaken by D.J. Noyes of Water Street Designs in Stonington, CT. The property has a long winding driveway through mature woodlands. The gardens around the house feature specimen trees, perennial gardens, a pool rose garden, a blue garden and a shade garden.

The Garden of Peter Wooster
Roxbury, CT
The garden has been long admired for its intimate design and incredible collection of plants. Now nearing its fifth decade, it began as a collector’s garden. Over time it became recognized for its great plantsmanship and unusual perennials, shrubs, annuals, and exotics, as well as for its simple but elegant architectural form. Covering only a half-acre, there are six large, rectangular beds framed by grass paths with a border that ties it all together

Hollister House Garden
Washington, CT
Hollister House Garden is an American interpretation of classic English gardens: formal in its structure but informal and rather wild in its style of planting. Begun in 1979, the garden since that time has evolved into a unique synthesis of the formal and the natural, with paths, walls and hedges forming a magnificent backdrop to the garden’s exuberant plantings.
