"Why, you have a second arboretum here. We never dreamed there was a place like this."

These sentiments were expressed by eminent plant explorer Ernest Henry "Chinese" Wilson and botanist Alfred Rehder, who traveled from Boston’s Arnold Arboretum to Blithewold on August 5, 1926.

The Arboretum History

Blithewold's trees have attracted attention throughout its history. From the mid to late 1800s, former owner, John Gardner planted many of the exotic trees that so excited the visitors from the Arnold Arboretum in 1926. Today the maturity of the collection, as a whole, is one of the character-defining features of the property, and it continues to draw visitors including botanists, garden groups and home gardeners looking for ideas and inspiration.

We are fortunate to have landscape architect John DeWolf's handwritten notes from 1895 containing his original vision for the property. He designed an informal landscape of gently sloping lawns with wide borders of flowers, trees and shrubs. Gravel paths meandered through the grounds to each distinct garden area. DeWolf laid out the Bosquet, planted a Nut Grove and designed an extensive Shrub Walk from the Bosquet to the Bay.
DeWolf heeded Blithewold's owners Augustus and Bessie Van Wickle's request for exotic as well as native trees and planted species from Europe, China and Japan as well as North America. It was thanks to his design that a border of protective evergreens grows along the northern edge of the Great Lawn, while deciduous trees and shrubs provided shade and interest along the south side. Nursery lists from 1908-1911, included hundreds of woody plants representing scores of species. Today there are about 500 species in a collection of approximately 2,000 trees and shrubs. Metal plant labels identify many of the plants. The collection boasts a variety of flowering trees and shrubs, weeping forms of deciduous and evergreen trees and venerable specimens of native trees.

The horticultural staff continues to propagate the property's most unusual or hard- to- find plants and maintains a replanting program to replace trees that have reached the end of their lifespan.

Blithewold offers its visitors today the same kind of experience enjoyed by its owners and their friends a century ago. Everywhere one walks, or looks, is something that was inspired by the family's love of plants, gardens and this very special place by the Bay.

Aboretum Accreditation

Blithewold Mansion, Gardens & Arboretum in Bristol, RI has been awarded a Level II Accreditation by the ArbNet Arboretum Accreditation Program and the Morton Arboretum, for achieving particular standards of professional practices deemed important for arboreta and botanic gardens. The ArbNet Arboretum Accreditation Program is the only global initiative to officially recognize arboreta at various levels of development, capacity, and professionalism. With this achievement, Blithewold takes its place among only 107 similarly accredited arboreta across the globe. Blithewold is also now recognized as an accredited arboretum in the Morton Register of Arboreta, a database of the world’s arboreta and gardens dedicated to woody plants.

The Great Lawn

The sweeping 10 acre Great Lawn and its views to Narragansett Bay is the perfect setting for over 500 different kinds of trees and shrubs. In 1926, Arnold Arboretum’s plantsmen Ernest “Chinese” Wilson and Alfred Rehder visited Blithewold and were awestruck by the variety of plants they found. In a letter to her daughter, Bessie Van Wickle McKee wrote, “They were frankly amazed to find so lovely and interesting a place here and kept saying, ‘Why you have a second arboretum here; we never dreamed there was a place like this.’”


The Bosquet, French for “woodland,” features a tall canopy of deciduous trees, evergreen groundcovers, and open views within. The Bosquet has been an integral part of Blithewold’s landscape since its conception by John DeWolf in 1895. The woodland space is a delight in any season—daffodils in spring, wildflowers, ferns, and cool shade in the summer, colorful leaves in autumn, and protective solitude in winter.

Nut Grove

Bessie Van Wickle McKee amassed a collection of nut trees and planted them just west of the Bosquet. Among others, Manchurian Walnuts, Bitternut, Butternut, Hickory, and Chinese Chestnuts were included in the collection. A few of the nut trees still grace the area today.

Enclosed Garden

This garden is the oldest on the property and features winding pathways, a rolling lawn surrounded by mature trees and shrubs, and the Summerhouse, which looks out on Blithewold's original Giant Sequoia, planted in 1911. It is the tallest Giant Sequoia on the East Coast.

Shrub Walk

John DeWolf planted a border of evergreen trees along the north side of the Great Lawn to provide shelter from the harsh northwest winter winds, and to protect the extensive collection of shrubs, both native and exotic, evergreen and deciduous, that he planted from the Bosquet to the Bay. Evergreen tree specimens of note include: Giant Sequoia, White Pine, White Spruce, Arborvitae, False Cypress, and Silver Fir. (The Shrub Walk plan is the only original plan available in the Archives.)
