This year’s symposium will look at some of the influences being part of the Pacific Rim has had on our Northwest gardens. Our four speakers will help us better understand this connection.

Raymond J. Larson
, Curator of Living Collections at the University of Washington Botanic Gardens, will present Around the Pacific in a Day: The Pacific Connections Garden at the UW Botanic Gardens. He will talk about plants from five regions around the Pacific Ocean—New Zealand’s South Island, the mountains of western China, southeast Australia, southern Chile and the Siskiyou Mountains of southern Oregon that created this garden. In his discussion of each display Ray will focus the best performing plants for our Pacific Northwest gardens.

Nao Donuma
, a fourth-generation gardener and the Executive Director at Yoshoen Corporation, which has been involved in garden design, construction, and maintenance for over 70 years in Niigata, Japan, will discuss his cross-cultural gardening experiences, My Experience Both in the Pacific Northwest and Japanese Gardens. Nao trained in both in Japan and the Pacific Northwest, where he was an intern at the Miller Botanical Garden. He will compare gardening in the Northwest with Japanese gardening. He will include a brief introduction to Japanese gardens from traditional to contemporary with some traditional garden techniques and design theories, and share with us ideas that can be applied to gardening in our Northwest gardens.

Douglas Justice,
the University of British Columbia Botanical Garden Associate Director and Curator of Collections, will present Southeastern Tibet in the Footsteps of the Plant Explorers. His lecture will take us along on his recent botanical expedition along the Tibet-Sichuan highway following in large part the Yarlung Tsangpo (ultimately the Brahmaputra in India) and its tributary rivers as they flow through southeastern Tibet. Ascending out of these often impressive valley bottoms were frequent sorties into the mountains and over high passes along secondary and lesser roads—many, the long-established tracks used by generations of Tibetan herders. In some cases, these were the same routes used by early 20th century plant collectors, including Frank Kingdon Ward, whose journeys in this area inspired his writing of the classic volume In the Land of the Blue Poppies. This plant hunter’s paradise boasts not just a wide diversity of amazing landscapes, but an astonishing variety of plants—Meconopsis, maples, Incarvillea, orchids, cypress, jasmines and rhododendrons to name a paltry few.

Daniel Hinkley
, teacher, writer, lecturer, consultant, nurseryman, naturalist, gardener and plant hunter, will take us to the southern hemisphere with Chilean Translation. The flora of the southern Andes on a whole dependably translates to cultivation in the Pacific Northwest better than any other in the southern hemisphere. Dan Hinkley will explore the many plant species native to this long, skinny country that deserve greater recognition in our western slope landscapes.
