(K2) The Forgotten Elements of Good Design: Texture, Movement and Fragrance (Dan Hinkley). The often neglected elements of powerful landscape design include utilizing the textural contrasts of good foliage, integrating elements into the garden that are charged with kinetic energy and taking full advantage of fragrant flowers and/or foliage by proper placement.  Dan Hinkley will share with you his thoughts on integrating the use of these principles along with suggestions of plants and plant combinations to best achieve these effects. Dan Hinkley is a teacher, writer, lecturer, consultant, nurseryman and gardener who has been recognized with numerous awards, and was one of the co-founders of the renowned Heronswood Nursery in Kingston, WA. He now maintains his garden, Windcliff, in the Pacific Northwest. He has been described as the ‘Indiana Jones of the Plant World’, with an ‘inconvenient fear of heights’, given his penchant for collecting plants on mountaintops. He is committed to solid and sustainable horticultural practices, above average garden plants, landscapes of distinction and raising the collective awareness of the diversity of plant life on Earth as well as the magic and mysteries of our natural world. He has been featured in the New York Times, New York Times Magazine, Fine Gardening, Horticulture Magazine, and Sunset Magazine. He has appeared on Martha Stewart television, where he served as a gardening consultant for 10 years. He has also appeared in and served as a horticultural consultant for the PBS Nova program ‘The First Flower‘.

(7B) A World of Clematis (Linda Beutler). There are 300+ species of clematis, located on all of the major continents except Antarctica. From the smallest (8″ x 8″ shrublets at the timberline of the south island of New Zealand) to the tallest (Clematis vitalba of the British Isles & Europe reaches 60′), clematis reside in steppes and swamps, in jungles, in the piney woods of Florida and the shale barrens of Virginia. Clematis are usually vines, but fully 25% of the known species are non-climbing herbaceous perennials and shrubs. With this much variety, it is amazing the taxonomists haven’t pulled the genus apart! Join Rogerson Clematis Collection Curator Linda Beutler for a world tour of clematis including the latest large-flowered hybrids. Resumes are supposed to be short and to the point, but Linda Beutler considers her first book, Gardening With Clematis (Timber Press, 2004), to be the 72,000-word resume that earned her the position as first curator of the world renowned Rogerson Clematis Collection (she began in July 2007). Linda’s love of gardening began with harvesting strawberries with her grandfather at the age of three, and being given her own plot for radishes and string beans at age five. Her home garden in the Sellwood neighborhood of Portland, Oregon reflects her garden passions, including old garden roses, herbaceous perennials and shrubs for cutting, and her 200 favorite clematis. Linda has been an adjunct instructor of horticulture at Clackamas Community College in Oregon City, OR since 1996. She is the current President of the International Clematis Society, and the author of Timber Press’ Plant Lovers Guide to Clematis (March 2016).

Concurrent Session #9, 3:30-4:30 pm

(9A) Better Vertical Vegetable Gardening (Harry Olson). There are two good reasons to garden vertically.  First, the plants love it.  Second, many of us need to garden vertically because we have so little horizontal space.  We need to go up, not out.  In either case, it works well.  Plants love to be grown up.  They get more light and better ventilation, resulting in less disease and bigger and better harvests.  The gardener is happy because vertically grown plants are much easier to maintain and harvest.  No need to bend over, just reach out to harvest. The secret to a good vertically grown garden is the techniques used and selecting plant varieties that prosper when grown vertically.  This class will cover these issues in detail and you will be ready to “Go Vertical” afterwards.  Join us to learn how to garden better, easier and more productively. Harry Olson is a lifelong gardener and a Master Gardener since 2008.  Harry specializes in grafted vegetable and vertical vegetable gardening.  He has a small urban home and garden in Salem, Oregon, which he has transformed into a vertical/grafted vegetable showcase.  It was a 2011 OSU Mini-College (Oregon’s statewide Master Gardener Conference) tour garden and has about 200 hundred visitors each year.  Harry has developed elegant, efficient and inexpensive vertical gardening solutions that produce huge crops in small spaces.  Harry has also grown and tested many varieties of vegetables to identify the best producers when grown vertically. Harry speaks frequently to garden groups and seminars and is a regular guest on garden radio and television shows.  He has conducted numerous public trials of emerging garden varieties and technologies.  In 2016, he led a team of three Master Gardeners conducting a “Master Gardener Grafted Vegetable Demonstration Garden” in the Oregon Garden, which was recognized with an Oregon Marje Luce Search for Excellence Award.

(9B) Urban Trees and Wildlife (Brian French). What are the benefits of snags to wildlife? How do we value deadwood, dead trees and decay? What species use dead trees? As an arborist, it is my job to evaluate trees and offer options to mitigate risks in our urban and rural areas. Wildlife habitat exists in trees in the form of cavities, dead snags, or broken tops. During this class, we will discuss how to recognize wildlife and safely provide habitat for cavity-dwelling species such as wood duck, chickadee, nuthatch, tree swallow, woodpecker and owl. We will also examine laws that protect specific wildlife species and how to steward land under those laws. Brian French founded Portland, Oregon-based tree care company, Arboriculture International LLC in 2013.  He is a climbing ISA Certified Arborist and Qualified Tree Risk Assessor. Serving as coordinator for the Oregon Champion Tree Registry and Chair of the Portland Heritage Tree Program, he focuses on the preservation of significant, old trees and their associated flora and fauna. Brian facilitated various ongoing wildlife habitat projects including salmon habitat restoration, snag development, red tree vole surveys and developing urban wildlife guidelines. In Oregon, he is a rescue volunteer for organizations that rehabilitate injured birds of prey.

(9C) The Effects of Phenoxy Herbicides on Landscape Trees and Shrubs (Paul Pugliese)Extension agents have noted a lack of understanding by arborists, green industry professionals, and homeowners about modes of action of herbicides, their environmental fate, and potential herbicide injury that may be caused by soil mobility of phenoxy herbicides. This presentation focuses on the potential for phenoxy herbicides to affect non-target trees and woody ornamentals in landscape settings due to poor application choices. This is an issue that’s commonly encountered in the landscape industry, as seen by numerous plant samples submitted to local Extension offices diagnosed with phenoxy herbicide injury. The purpose of this presentation is to raise awareness about this important issue and provide practical tips on avoiding potential damage and liability. Paul Pugliese grew up on a family-owned and operated Hereford/Angus beef cattle farm in Kingston, GA.  He received a Bachelor of Science degree in Horticulture, with a minor in Biology, from Berry College, Rome, GA in 2001, and a Master’s degree in Plant Protection and Pest Management (MPPPM) from the University of Georgia in 2003.

(9E) Heirlooms, Hybrids, and GMOs – Oh My! (John Porter). What is an heirloom? What is a hybrid? Is a hybrid a GMO? There’s much confusion these days about the genetics of common garden seeds. As Master Gardeners, it is important to be able to understand and educate the public on emerging issues using scientifically sound information.  In this workshop, we’ll learn the basic science behind the terms heirloom, hybrid, and GMO and discuss current controversies surrounding genetic engineering.  We’ll clear up some misconceptions and help provide valuable information that can help Master Gardeners answer some of the hot-button issues of the day.  John Porter is the Ag and Natural Resources Agent for West Virginia University Extension Service in Charleston, the state’s capital.  Much of his extension programming focuses on urban agriculture and home horticulture.  He is a member of the Garden Professors, a group of extension professionals working to educate the gardening public with science-based information, and he works with the National eXtension Master Gardener Social Media team.  He writes the Garden Guru column for the Charleston Gazette-Mail which is published on Sundays through the statewide paper, and is available through his various social media channels (@wvgardenguru) and website ( He has a BS degree in Botany from Marshall University and a MS degree in Horticulture from West Virginia University.

(9F) Photographing Your Garden Through New Eyes (Mark Turner). Gardeners use a palette of plants and hardscape elements to create living works of art for their enjoyment or to share with friends, neighbors, or the public. In the process we develop a mental picture of what our gardens look like and sometimes miss other ways of seeing. In this program professional garden photographer Mark Turner shares his insights into garden photography, inspiring gardeners and garden lovers alike to see their gardens in new ways as they learn basic photographic techniques. Using examples from his extensive garden photo library, he will show the effects of different qualities of light, composition tools, perspective, point of view, juxtaposition, and seasonal change.
