Friendship Grove in May 1989

Friendship Grove in April 2005

University of Washington Friendship Grove of Trees

    Autumn 1985 marked the 25th anniversary of the International Friendship Grove of trees, located on the University of Washington Campus Parkway between Brooklyn Avenue NE and 11th Avenue NE. The grove was an ambitious attempt to commemorate the 5th World Forestry Congress held in Seattle in 1960, via a living, permanent symbol, and to provide a down-to-earth demonstration of the friendship and unity among the 66 countries represented at the congress. Even as memories of the congress gradually fade away, the trees themselves take on an increasingly valuable role as a miniature arboretum.
    For more information, consult these early articles:
American Forests, November 1960: "Many Nations, One Goal" pp. 10-15, 40-47.
American Forests, June 1966: "Seattle's Trees For Peace" pp. 34-37.
University of Washington Arboretum Bulletin, Winter 1960: "The Arboretum and the Fifth World Forestry Congress" pp. 33-34.
University of Washington Arboretum Bulletin, Winter 1964: "A Further Report on the International Friendship Grove" pp. 82-85, 113.

    In 1985 I published a list of the trees remaining as of then, in:
University of Washington Arboretum Bulletin, Summer 1985: "The Friendship Grove Revisited 25 Years Later" pp. 20-26 (the list on pages 24-26).

    In my 1989 book Trees of Seattle the same list, updated, appeared on pages xxiii-xxvi. The version you see below is yet another update, as of January 2003. At this point, as before, some trees that died were replaced with other kinds; some that died have not been replaced at all; most are currently unlabeled and others mislabeled; and the western end is an overgrown mess. But in general, the grove has proved a success. As of January 2003 there are 52 trees remaining, 28 of them unlabeled. In addition, at the western end near 11th Avenue NE, there are wild specimens of the following trees: European White BIRCH, Western White PINE, Common HAWTHORN, English HOLLY, Bigleaf MAPLE, and MADRONA. These are well established and obvious; in addition are various little Algerian FIR seedlings, and the like.
    The following listing of the trees is arranged as they exist going from east to west, with a loop around the western end where the dense Escallonia shrubbery is. Most name plaques are gone, others bear inaccurate names. A tree representing a certain country is not necessarily native to that country.
