December 14, 2020: A Short History of Seed and Nursery Catalogues – Alice K. Formiga, Assistant Professor of Practice, Department of Horticulture, Oregon State University Please use this link to register for this webinar via OSU Zoom.
As you thumb through a new nursery or seed catalog, have you ever wondered how they have changed from last year? 5 years ago? 100 years ago? Historic seed catalogs provide an interesting window into the history of plant introductions, changing cultural tastes, and technological developments.
Join us for a talk on how seed and nursery catalogs in Europe and the US have evolved from the printed catalogs and seed lists of the 1600s to the online catalogs of the present. This talk draws content from the Oregon State University collection of 2,000 seed and nursery catalogs.
Alice Krinsky Formiga is a former trial garden manager and horticultural advisor for Shepherd’s Garden Seeds and Renee’s Garden Seeds. She holds a Masters of Library and Information Science from the University of Washington, and works as the director of eOrganic at the Oregon State University Department of Horticulture.
Alice wrote the text of an online exhibition on the seed and nursery catalog collection at the Oregon State University Valley Library. It is available at http://scarc.library.oregonstate.edu/omeka/exhibits/show/seed/introduction/collection/

January 13, 2020 : Beyond Glyphosate: How to Think & Talk about Safety and Risk of Pesticides – Kaci Buhl, Associate Professor of Practice, Environmental and Molecular Toxicology Department, Oregon State University
Glyphosate is the most commonly used pesticide in the world and has been very much in the news. With many head-spinning claims and counter-claims swirling around the use of Glyphosate, there is no better person than Kaci Buhl to clarify for us what is supported by scientific research.
In this talk, Kaci will discuss what research tells us about Glyphosate while giving us the tools to think more broadly about risk and safety of all pesticides.
Kaci Buhl is uniquely qualified to talk about the risk and safety of Glyphosate. Buhl co-directs the Pesticide Educational Resources Collaborative, a program that administers $1,000,000 annually in support of new pesticide-related educational materials. She also leads the Pesticide Safety Education Program in Oregon which hosts live recertification events for over 1,000 licensed pesticide applicators.
Kaci holds a B.S. in Entomology and M.S. in Integrated Pest Management from Michigan State University. In 2018, she received the Distinguished Achievement in Pesticide Safety Education Award. * eligible for recertification credit.

February 10, 2020: Dwarf Conifers – Sam Pratt
Midwinter is the perfect time to think about dwarf conifers. Sam Pratt brings his years of experience in propagating and growing these beautiful essentials to our meeting.
Trees and shrubs are the backbone of any garden. And evergreens are the paperweights that give our gardens a sense of presence during winter, when they go from providing supporting roles to being the stars of our outdoor spaces. Dwarf conifers provide that presence in smaller and urban yards, and, in large spaces, they provide the shapes, colors, and textures to occupy the winter understory beneath larger trees.
Sam will share essential information about selecting, designing with, propagating, planting and caring for these critical plants.
Sam Pratt is the resident plant expert and inventory manager at Conifer Kingdom (retail) and Rare Tree Nursery (wholesale), sister nurseries in Silverton that specialize in dwarf conifers and Japanese maples, and propagate and sell over 1000 varieties. He is also an avid photographer of, and spokesperson for, these essential plants. He is an active member of American Conifer Society and a consultant for the Dwarf Conifer Collection at the Oregon Garden.
March 9, 2020: Culinary Breeding Network: Building Community among Breeders, Farmers, Chefs, Retailers & Eaters to Create Better Varieties for All – Lane Selman, Professor of Practice, Department of Horticulture, Oregon State University
In 2011, the Culinary Breeding Network was formed to bring together plant breeders, seed growers, farmers, chefs, produce buyers and other consumers to discuss and identify preferences and traits of culinary excellence for vegetables and grains.
Incorporating chefs, farmers, produce buyers and other stakeholders into the plant breeding process gives breeders deeper insight into preferred traits while also increasing awareness and understanding of organic plant breeding to a broader audience.
This presentation will review recent efforts in vegetable breeding as a result of the Culinary Breeding Network’s work. It should help inform local gardeners of new options in vegetable varieties.
Lane Selman is the founder of the Culinary Breeding Network and has worked with organic farmers, plant breeders and chefs for 15 years. Lane’s work has been featured in the media including Food & Wine, The Wall Street Journal, Civil Eats, Food Tank, The New York Times and Eating Well magazine. Lane has been the recipient of many awards, including the Award of Excellence for Organic Advocate by the Oregon Organic Coalition in 2016.
Lane grew up on a citrus farm her Sicilian great-grandparents planted in 1919 on Florida’s space coast. She has a B.S. in Agronomy and a M.S. in Entomology, both from University of Florida. In 2000, she moved to Oregon and since 2005 has been an agricultural researcher at Oregon State University working with diversified, organic farmers on collaborative research projects.

May 11, 2020 via oregonstate.zoom: Bee-Friendly Gardening Practices – Gail Langellotto, Oregon State University Garden Ecology Lab click here for the full presentation
Although Master Gardeners are trained in university research, nearly all of the gardening advice they dispense to home gardeners are derived from agricultural research. This is because research funding concentrates in commercial crops while there is little to no money to support research in gardens.
Bucking this trend, Dr. Gail Langellotto of Oregon State University formed the Garden Ecology Lab in 2016. An underlying premise of the group’s work is that gardens are important and understudied systems that are key to building more sustainable, healthy and just communities.
Since then, studies on urban soil, native plants, and garden pollinators have generated significant findings to inform gardening practices.
This talk draws from a 3-year study of Portland area gardens. It will review the plants and practices that have been shown to promote native bee abundance and diversity in home gardens. It will also highlight the importance of urban and suburban gardens to bee conservation efforts, and small changes that any gardener can make to benefit bees.
Gail Langellotto is a Professor of Horticulture, where she also coordinates the statewide Extension Master Gardener Program. She received her B.S. in biology and M.S. and Ph.D. in entomology, all from the University of Maryland. Her lab group, the Garden Ecology Lab at OSU, studies the plants, animals, people, decisions, and management practices that either improve or degrade a garden’s ability to promote environmental and human health.

June 8, 2020 via oregonstate.zoom: The New Clematis Horticultural Classification – Linda Beutler, Curator, Rogerson Clematis Collection Click here for the full presentation.
If you grow clematis and are unsure of proper pruning techniques for them, you are not alone! Confusion over clematis pruning has long been recognized by experts as a major issue and, in 2016, the International Clematis Society and the Royal Horticultural Society UK formed a partnership to address it.
Click here for the clematis handout: Clematis classification pruning
Over the past three years, Linda Beutler chaired a panel of experts to simplify the classification system and pruning instructions. An initial revision that takes 14 “groups” down to 6 “ranges” was approved by both organizations in June 2019.
What does this mean to the home gardener? Simply put, pruning Clematis has become clearer and easier than ever. In this illustrated lecture, Linda will share the most recent and authoritative information on how to grow, care for, and prune clematis.
Linda serves as curator of the Rogerson Clematis Collection (FRCC), North America’s only accredited clematis collection and she is the immediate past-President of the International Clematis Society. In July 2018 she was given a Golden Clematis Award by the International Clematis Society for her service to the Society and the genus Clematis. She has been an adjunct instructor of horticulture at Clackamas Community College (CCC) since 1996, specializing in herbaceous perennials (their cultivation and use) and cutting gardens for home and commerce.
Linda lectures nationally on numerous gardening topics, and she has made numerous appearances on Portland’s Garden Time TV.
