The Grove of the States is an arboretum of state trees for all 50 states, originally planted in 1967. It is believed to be the oldest grove of state trees in the country.

History of the Arboretum

In 1967 Oregon Attorney General  Robert Y. Thornton hosted the 61st annual conference of the National Association of Attorneys General in Portland. As part of a conference event, Thornton planned for the Grove of the States as an homage to First Lady, Lady Bird Johnson, and her work fostering the 1965 Highway Beautification Act. The First Lady pushed hard for freeway right-of-ways filled with green landscaping and wildflowers instead of endless advertising.

When signing the bill, President Lyndon B Johnson said, “We have placed a wall of civilization between us and the beauty of our countryside. In our eagerness to expand and improve, we have relegated nature to a weekend role, banishing it from our daily lives. I think we are a poorer nation as a result.”

After saying, “Beauty belongs to all the people,” Johnson signed the bill and gave the first pen to Lady Bird, kissing her on the cheek.

Thornton involved two large Oregon emissaries in creating the Grove: The Oregon State Highway Department (today—the Oregon Department of Transportation) contributed the site, and the Oregon Association of Nurserymen (now known as the Oregon Association of Nurseries) provided tree stock for the original collection.

Members of the Oregon Green Thumb Program were responsible for the hands-on construction and planting of the site. In response to the mid-20th century’s “War on Poverty,” the federal government created this small rural demonstration program to help economically challenged retired farmers. It offered them a chance to put their “green thumbs” to work beautifying America, while they earned much-needed income. It was common to see crews wearing bright green hard hats (throughout Arkansas, New Jersey, Oregon, and Minnesota) painting picnic tables, fixing playground equipment, and serving as groundskeepers for city parks and national forests.

Restoration Efforts

In 2015, Travel Information Council in partnership with Oregon Department of Forestry, Oregon Department of Transportation, Friends of the Trees and numerous individual volunteers began restoration efforts to improve the health and wellness of the Grove. It received heritage status when it turned 50 in 2017. Today visitors can view the 50 trees off two gravel pathways.
