SUMMARY:Woodpecker: A Year in the Life of North American Woodpeckers with Paul Bannick
DESCRIPTION:  \nWoodpeckers are the heart of North American forests in many ways: their distinctive drumming sounds out a familiar rhythm\, while their presence supports owls and a countless other creatures. Award-winning author and photographer Paul will present highlights from his latest book\, “Woodpecker: A Year in the Life of North American Woodpeckers” (Mountaineers Books\, 2025)\, which illuminates the often secret lives of this bird family. He captures woodpeckers in every season: their courtship and nest selection in spring; life in the nest during summer; fledging and gaining independence in autumn; and the challenges of surviving the winter. Paul also takes a closer look at the most important woodpecker habitats in North America and what we can do to protect them. \nSpeaker’s bio: \nSeattle-based Paul is an author and wildlife photographer specializing in the natural history of North America\, with a focus on birds and habitat. He creates images that foster intimacy between viewer and subject\, inspiring education and conservation. He is the author of numerous titles\, including two best-selling bird books\, “Owl: A Year in the Lives of North American Owls” (Braided River\, 2016) and “The Owl and The Woodpecker\, Encounters with North America’s Most Iconic Birds” (Mountaineers Books\, 2008). Paul has won awards from several prestigious photography contests\, including those hosted by Audubon Magazine and the International Conservation Photography Awards. After working in the computer software industry for many years\, he transitioned to the non-profit world. He is currently the director of major gifts for Conservation Northwest.

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. James designed the first native woodland garden in China at Lotus Lake\, Beijing\, the acclaimed New Silk Road Garden at the Beijing International Expo\, and the planting of the Monet Garden in Chengdu. Since retiring\, James has been engaged in major design and management projects in the UK and internationally. He is a sought-after writer and speaker and was recently appointed to the RHS Council for a five-year term.

SUMMARY:Sweet Pea School with Marryn Mathis
DESCRIPTION:It’s time to get your sweet peas started\, and we are excited to welcome Marryn Mathis\, aka The Sweet Pea Queen\, to Seattle for our first in-person event of the year. Marryn is an authority on sweet peas and the author of “Sweet Pea School: Growing & Arranging the Garden’s Most Romantic Blooms” (Chronicle Books\, 2025). Every year she grows 32\,000 individual plants and 150-plus varieties at The Farmhouse Flower Farm\, her family’s ten-acre production site in Stanwood. Her passion and knowledge is infectious and will grow your confidence to cultivate this intoxicatingly fragrant flower. She will share its history and wow us with powerful and proven techniques for every growing stage – from sowing through harvest. She’ll educate us about the advantages of spring vs. fall seed starting\, dispel myths (no need to presoak seeds!) and dispense her tried-and-true wisdom (no to heating mats or bottom watering). Marryn will embolden you to maximize the productivity of this cherished flower in your own garden and expand your appreciation for its profusion of colors and varieties.  \nSpeaker’s Bio: \nMarryn worked in a corporate setting for over 20 years before actualizing her long-held dream of owning a farm and growing flowers. In less than a decade\, The Farmhouse Flower Farm has become one of the country’s foremost producers\, with a powerhouse mail-order business in seeds\, dahlia tubers\, corms and bulbs. Marryn has a robust social media following and offers online and in-person workshops that regularly sell out. \nPlease note: This is a live event and will not be recorded. \nNHS thanks the Woodinville Garden Club for generously sponsoring this event.\n \nAdditional Resources: \nhttps://www.seattletimes.com/pacific-nw-magazine/stanwoods-sweet-pea-queen-shares-her-floral-passion-and-pro-tips/ \nhttps://www.slowflowerspodcast.com/2025/02/19/episode-704-sweet-pea-school-with-marryn-mathis-of-the-farmhouse-flower-farm/ \nhttps://www.instagram.com/thefarmhouseflowerfarm/ \nhttps://www.facebook.com/profile.php?id=100064278115690&sk=about

SUMMARY:Gardens of Texas: Visions of Resilience with Pam Penick
DESCRIPTION:Pam Penick’s latest book\, “The Gardens of Texas: Visions of Resilience from the Lone Star State” (Timber Press\, 2025)\, celebrates the tenacity and range of gardening approaches across her home state. Whether a pocket prairie in an urban neighborhood\, a crevice garden in Central Texas or a desert oasis in the west\, these human-made landscapes are not only visually captivating\, but designed to thrive in extreme conditions: intense heat\, drought\, floods and freezes. Although Texas is half a continent away from the temperate PNW\, the book presents a bounty of relevant lessons to all gardeners navigating a rapidly changing climate. \nPam captures the motivations\, challenges\, joys and rewards of 27 intrepid garden-makers who\, through true-grit determination and innovation\, have adapted to Texas’ extreme climates and challenging growing conditions. By implementing hardy plant choices\, rainwater harvesting\, native lawns and other responsive design strategies\, they’ve created dynamic\, thriving gardens that work in harmony with the state’s natural beauty. Penick presents these spaces as case studies\, offering practical takeaways and savvy plant recommendations.  \nSpeaker’s bio: \nAustin-based Pam is an accessible and influential garden writer\, speaker and advocate for climate-resilient design\, known for inspiring waterwise\, wildlife-friendly landscapes for nearly two decades. For 10 years she ran a landscape design business helping Texas homeowners replace thirsty lawns with waterwise gardens of native and well-adapted plants.   \nPam is the voice and photographer behind “Digging\,” her website about “cool gardens in a hot climate”. In addition to her latest book\, Pam authored “Lawn Gone!” and “The Water-Saving Garden.” Her writing has appeared in major magazines\, like Better Homes & Gardens\, Fine Gardening\, American Gardener. She’s also the founder of Garden Spark\, an Austin-based speaker series on design and ecology\, where she brings fresh ideas and bold voices to the local gardening community.

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: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: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.
