Origins of the Foundation and Garden

Following initial discussions among Rhododendron enthusiasts in the Pacific Northwest, the real origin of the Rhododendron Species Foundation may be said to lie with a visit to England by Dr. Milton Walker in March of 1964.  The purpose of his visit was to explore the possibility of importing cuttings, many from the original wild plants, of the best forms of Rhododendron species growing in both public and private British gardens.  Among the gardens he visited were Windsor Great Park, Wakehurst, Leonardslee, and the major Cornish gardens, including Caerhays.  In September he wrote to these gardens, as well as to Brodick, Wisley, Corsock, Leggygowan (Northern Ireland), Glenarn, Logan House, Younger Botanic Garden of Benmore, Stronachullin, and the Royal Botanic Garden in Edinburgh, to request cuttings, but there was a problem.  Due to American import regulations, the cuttings could not be brought into the United States directly from Europe. They could, however, be imported into Canada due to an extraordinary flexibility on the part of the Canadian Department of Agriculture and Canada Customs.  So Dr. Walker contacted Mary Grieg, owner of the Royston Nursery on Vancouver Island, to inquire if it would be possible for the cuttings to be imported and propagated in British Columbia.  As a result of Mary Grieg’s efforts, arrangements made with the University of British Columbia led the first shipment of cuttings arriving there from Brodick Castle in September 1964.  Subsequent shipments arrived in Vancouver that same fall and over the next several years from other major British gardens. At UBC they were propagated by Evelyn Jack (now Weesjes), who in the process took on much of the correspondence with the British sources.  She grew the plants for up to two years, and, with a sharing agreement, she kept one plant of each selection at UBC and sent the others on to Oregon to become a permanent part of the RSF collection.

The RSF rhododendron collection was first housed on Milton Walker’s property at Pleasant Hill, near Eugene, Oregon. The first plants were sent there in October 1968. Three years later the collection was moved to the property of RSF board member P.H. (Jock) Brydon, near Salem, Oregon. By the fall of 1973 it had become apparent that the collection was becoming too large for the Brydon property, and a committee met with George Weyerhaeuser (a relative of committee member Corydon Wagner), who was immediately and enthusiastically receptive to the idea of providing space on the new Weyerhaeuser corporate campus in Federal Way, Washington. In 1974 the Weyerhaeuser Company generously leased at no cost a permanent site of 24 acres for the collection. The following year the collection was relocated from Salem to the Federal Way site and planted in accordance with the geographic origin of each species.

Growth of the Foundation and the Garden

The founders of the Garden recognized the need for additional support if the goal of a world-class garden was to be achieved. They started a membership program was in 1976; it now has representation from 15 different countries. They also began to distribute plants to members at about this time, with the profits helping to support the garden. Finally, they opened the Garden to the public on a limited basis in 1980, established a coordinated volunteer program, and completed a garden master plan that proposed replanting the collection in the Garden to reflect taxonomic groups (those species that are most closely related are planted near one another).  This replanting was completed in 1984.

The RSF hired Ken Gambrill in 1974 to be the first Curator, but he resigned to start his own nursery and consulting business in 1984. The Foundation then hired Richard Piacentini as Executive Director and Curator; he served in this capacity until his departure in 1991. From this date until 1998, the various Presidents of the Board acted as de facto Executive Directors. Finally, in 1998, then Garden Manager Richard Peterson took on the role of Co-Executive Director along with Steve Hootman who was then the Curator. Each of the two retained their former positions as well as serving as co-directors of the RSF. In 2009 Rick Peterson, who had been with the RSF for 23 years, originally as a gardener and later as Co-Executive Director with Steve Hootman, resigned. At this point the Foundation leaders named Steve Hootman Executive Director of the RSF and RSBG, as well as Curator.

As membership grew and leadership developed came the need for more permanent funding to increase and improve the facilities. In the late 1990s a major fund-raising drive to increase the endowment was undertaken with a $400,000 matching grant put forward by long-time Board member Robert Franz. With the full support of the board and membership, this amount was matched and even exceeded. This substantial addition to the endowment greatly increased the available funding for operations and for needed facilities.

Growth and Expansion of the Garden

In 2005, a new propagation greenhouse, fitted with a completely automated computerized control system, was built in the RSF Nursery. The majority of the funding for this project resulted from the successful grant writing efforts of former President of the board, Honore Hacanson. The electrical work and a great deal of construction assistance were provided by a group of volunteers led by Paul Thompson. This volunteer work saved well over $10,000 in the cost of the construction. Paul and this same group of volunteers were also instrumental in the construction of the Rutherford Conservatory.

In early 2009 collaboration between the RSF and the Hardy Fern Foundation produced a “Victorian Stumpery” in the RSBG, an area of large stumps and logs to be planted mainly with epiphytic ferns and rhododendrons.

A tropical conservatory for the RSF had been contemplated since the early days of the organization to complement cooler climate rhododendrons with their subtropical cousins, the vireya rhododendrons. Serious exploration of funding, siting, etc. was not initiated until 1998. Several people contributed to finance the construction project over the succeeding years, some substantially, but the prime mover and contributor was long-time Board member Francis Rutherford. Finally, in 2008, the building fund was substantial enough for planning to begin in earnest and would be topped up by Fran in order to actually begin construction. After allowing for the permitting process and ground clearing, construction began in early 2009.

As plans and preparations were evolving, the original propagation greenhouse was converted as a secondary holding area for the vireya collection, both while the new conservatory was being built and for later use as a back-up facility. Francis Rutherford was on hand for the groundbreaking ceremony, but unfortunately he died before completion of the conservatory. He left his entire estate, totaling well over $1,000,000 including his home, to the RSF in the form of an endowment for the operation and maintenance of the newly named Rutherford Conservatory and for the cultivation of vireya rhododendrons.

Important to the further development of the Garden was the continued collection and propagation of new species. In 1995 Curator Steve Hootman participated in his first seed and plant collecting expedition to China. This was the first time that a staff member of the RSF had been able to take part in such an experience. Several species of Rhododendron that were completely new to cultivation as well as at least one species new to science were collected. Such was the success and positive attention resulting from this first expedition that the active acquisition of new wild material for a now rapidly growing collection continued on an almost yearly basis – and it continues to this day. After a few such trips in the late 1990s, Steve Hootman began organizing RSF-sponsored collecting trips with plant hunters from around the world as well as more leisurely “sight-seeing” and driving tours that RSF members could participate into experience rhododendrons in their wild habitats. Since that initial expedition in 1995, dozens of new rhododendrons and many dozens of new companion plants have been introduced into the RSF garden and general horticulture thanks to the success of these trips. In addition, the RSF has gained an even more prominent position in the horticultural and botanical worlds due to its being on the forefront of modern plant exploration.

Education has always been a primary goal of the RSF. As early as 1985 the RSF organized an International Rhododendron Species Symposium, held in Tacoma, Washington, in April 1985.  Another long-held educational practice of the RSF is to provide horticulture students with practical hands-on experience. The Student Intern Program was inaugurated in 1986.  Since that time, well over 50 budding horticulturists have worked and studied in the Garden and nursery. But education outreach to RSF members was also important. In 2004 exploratory work was initiated by Vice President Joe Ronsley and Executive member Chip Muller on the possibility of publishing an RSF yearbook. The first issue of this yearbook, Rhododendron Species, appeared in 2006. It was edited by Executive Directors Steve Hootman and Rick Peterson and was received with considerable enthusiasm. Beginning with the 2008 issue Prudence Holliger took over as Editor, with Steve Hootman and Rick Peterson as Associate Editors. The yearbook provided an incentive for membership in the RSF and gave the organization additional international stature and authority. The 2009 issue of the yearbook was accompanied by a separate Membership Directory, the first ever published by the RSF. It was financed by Ian Walker and assembled by him and his wife Jean and by Rick Peterson and Prudence Holliger.
