SUMMARY:60th Anniversary Symposium
DESCRIPTION:Beyond Tradition: New Visions in Plants and Planting Design\nBastyr University Auditorium\, Kenmore\nSaturday\, March 14th\, 2026  |  8:30 AM – 4:00 PM\n\n \n\nAbout the Symposium\n\nThis year the Northwest Horticultural Society celebrates six decades of sharing horticultural knowledge and creating a vibrant community in the process. In recognition of this milestone\, the symposium will feature horticulturist luminaries who will speak about new directions in plant selection and design. \n\n\nJoin us to expand your knowledge\, network and connect\, enjoy morning pastries and a boxed lunch\, and browse plant sales from Celestial Dreams\, Grow Girl Seattle and Windcliff Plants. \nWe look forward to celebrating this milestone with you! \nLectures and Speakers’ Bios\n\n\n\nJared Barnes\, Ph.D.: Planting with Perception: Using the Preference Matrix to Design Natural Plantings\nJared will delve into the Kaplan Preference Matrix\, a powerful model for understanding how people perceive and connect with landscapes. He will outline its four key factors: coherence\, complexity\, legibility and mystery\, and how they shape how we feel in outdoor spaces. With practical strategies grounded in naturalistic planting\, you’ll discover how to design landscapes that are ecologically rich\, visually compelling and deeply intuitive to explore. \nDaniel J. Hinkley: Take Two \nWindcliff\, the Puget Sound garden of Dan Hinkley and Robert Jones\, was established upon the bones of an older garden\, beginning in 2000. The highly destructive winter of 2024 forced Dan to reimagine a space that was already primed for reimagining\, both philosophically and aesthetically. He will discuss the inspirations and rationale for the new approach\, as well as the plants and processes he is employing to create a garden that will never be finished. \nAnnie Guilfoyle: Gardening into the Future: Is the Way We Are Gardening Changing? \nAnnie will present how gardens and planting design are changing and developing in the UK\, with an emphasis on those leading the way forward in terms of how we garden and the plants we use to help mitigate the difficulties of ever-changing and erratic climates. In addition\, she will share examples of her own work that experiments with the use of aggregates and sand. \nLisa Roper: The Chanticleer Gravel Garden: Xeriscaping in the Delaware Valley \nLisa manages the Gravel Garden at Chanticleer\, the internationally esteemed public garden located in Wayne\, Pennsylvania. This gently sloping site is planted with a mix of finely textured grasses\, gray-leafed Mediterranean plants\, drought-tolerant perennials\, hardy succulents and annuals grown from seed. She will introduce some of her favorite plants\, talk about plant combinations and planting techniques\, the importance of editing and using photography to inform design decisions. Thanks to Lisa for sharing the photo above taken at the Gravel Garden in June. \nRichie Steffen: Rooted in Excellence: Celebrating 60 Years of NHS \nRichie will present a pictorial history of NHS and will moderate the panel discussion. \n  \nThis is a live event and will not be recorded. \n___________________________________________________________________________________________________________________________________________________________________________________________ \nThanks to a generous donation from the Pendleton & Elisabeth Carey Miller Charitable Foundation\, we are able to offer the same pricing as last year for members.\nWe are grateful to Bartlett Tree Experts for their sponsorship of NHS educational programming. Fees from the symposium will support our educational programs\, as well as our community outreach grants and scholarships.

SUMMARY:Pastoral Gardens with Clare Foster
DESCRIPTION:  \nClare is the Garden Editor of House & Garden UK and will share fascinating details about the making of her newest book\, Pastoral Gardens (Montgomery Press\, 2024). A rhapsodic deep dive into gardens that blur the lines between intentional design and the wild landscape\, it offers intimate glimpses of twenty gardens in the UK\, the Continent\, U.S. and Africa – including projects by Dan Pearson\, Sarah Price and Tom Stuart-Smith. She will detail the history\, design and planting behind many of these gardens in this sumptuous meditation on bucolic beauty. \n The interviews I carried out for the book were fascinating\, veering off into philosophical\, environmental and sometimes spiritual territory and it made me realise how intimately people are connected to their gardens. They define who these people are. The gardens become an intrinsic part of their lives\, connecting them to the wider ecosystems we belong to.  — Clare Foster \nSpeaker’s Bio: \nClare was at Gardens Illustrated for nine years before joining House & Garden UK in 2005. She is a passionate life-long gardener – first on an allotment in London\, and now at her home in the English countryside\, where she cultivates a gravel garden\, a kitchen garden and herbaceous borders. She is also a freelance garden journalist and the author of six books.

SUMMARY:Demystifying Botanical Latin with Daniel Sparler
DESCRIPTION:Who says botanical Latin (also known as scientific nomenclature) has to be head-scratchingly hard? We’re all Homo sapiens (“intelligent humans”)\, so it’s not too much of a leap for us to figure out that Rhododendron macrophyllum (literally “red-tree large-leaf”) is the Pacific rhododendron\, the state flower of Washington. This class will cover the basics (who\, what\, when\, where\, why and how) of Latin binomial plant names and provide tools for further study to help us make sense of what we grow in our gardens. \nInstructor’s Bio: \nA third of a century ago NHS Board Member Daniel Sparler Daniel planted himself in Seattle’s Seward Park neighborhood and proceeded to construct a now notorious garden brimming over with thousands of specimens of cosmopolitan origin. He first joined the board of NHS in 2006 and has taught botanical Latin all over the Puget Sound region. Since 2020\, Daniel’s more than 60 Horticulturally Yours columns have been archived on the Northwest Horticultural Society’s website. \nThis is a live event and will not be recorded.

SUMMARY:Squaring the Circle on Biodiversity and Aesthetics in the Development of a New Garden with James Hitchmough
DESCRIPTION:Lecture Description in James’ own (lightly edited) words: \nMy professional life has run parallel with extensive UK Research Council-funded research into what lives in UK gardens. It had long been assumed invertebrates are hard-wired to prefer native plant species\, but research shows that our gardens are actually extremely rich in native invertebrates\, despite the fact that most gardens contain many non-native plants. Invertebrate diversity is richest where gardens are most spatially and taxonomically complex\, so gardening ambition drives greater richness. The realization that as gardeners\, we are wardens of our very own nature reserves has come as something of a shock\, and has raised questions about how one should balance nature conservation with the traditional aesthetic values of gardens. In this talk I will discuss how I have approached this in my own\, relatively new 2.5 acre garden in rural Somerset. \nSpeaker’s Bio: \nAfter receiving his Ph.D. from the University of Bath in 1984\, James held a lectureship in environmental horticulture at the University of Melbourne\, where he worked for 10 years and conducted research into nature-like plant communities as an urban form. He then spent 27 years teaching and researching in the Department of Landscape Architecture at the University of Sheffield. He retired in September 2022 and was named professor emeritus. \nJames has worked as a consultant on landscape projects around the world\, often using these experiences to translate his research into practice and policy. With Nigel Dunnett he was lead planting designer at the London Olympic Park (2007-14)\, following the publication of the first edition of “The Dynamic Landscape” (2004)\, a seminal text on the application of nature-like planting to the urban realm.  After 2010 he focused on projects in China\, often in collaboration with Chinese government agencies to advance the use of local native species in large scale nature-like design projects.

SUMMARY:Planting Designs from a Mediterranean Nursery Garden in Southwestern France
DESCRIPTION:In 2016\, UK horticulturalists Imogen Checketts and Kate Dumbleton broke ground on their property in southwestern France to create Le Jardin Champêtre. Since then\, it has become a highly regarded demonstration garden\, nursery and design practice infused with their love of the local scrubby garrigue landscape. Noel Kingsbury lavishly profiled Le Jardin for Gardens Illustrated and it’s featured in master garden photographer Claire Takacs’ book about some of the world’s most innovative and climate-smart gardens\, Visionary: Gardens and Landscapes for Our Future. \nChecketts and Dumbleton’s plant palette and design approach are naturalistic\, ecologically based and tailored to thrive year-round in the Mediterranean climate – once established\, plants receive little to no irrigation and low maintenance is key. The designers will share their most successful plant combinations\, both native and nonnative\, which include grasses\, perennials\, shrubs\, bulbs\, ground covers and lawn alternatives\, and how to layer them for maximum visual and ecological effect. \nThe Pacific Northwest climate is often described as Mediterranean; as summers become drier and hotter\, there are many lessons to be gleaned from the plantings and principles of Le Jardin Champêtre. Some plants will be familiar: achillea\, eriogonum\, miscanthus\, phlomis\, salvia\, stipa…but prepare to discover new ones\, some of which might very well enhance your own landscape. \nSpeakers’ Bios: \nKate Dumbleton studied horticulture at Nottingham Trent University’s Brackenhurst College\, where she won the student of the year award. Prior to that\, she earned a Master’s degree in French\, and worked in social research and project development for cultural heritage projects\, local food initiatives and environmental programs. She also qualified in permaculture design and was an active member of Ecoworks community gardens\, St. Ann’s Community Orchard and the Friends of Brackenhurst’s Victorian Walled Garden. \nImogen Checketts has two degrees: horticulture and garden design and landscape and heritage. She was head gardener at Pensthorpe Wildlife and Gardens in Norfolk\, where she designed and built the Wave Line Garden\, the Wildlife Habitat Garden\, and worked alongside Piet Oudolf to redesign and replant his first UK public project\, the original Millennium Garden. Imogen is an accomplished linocut artist and her horticultural interests include mixed perennial and grass planting\, planting for wildlife and dry gardens\, as well as woodland habitats and edible gardening. \n \n \n
