Join us as Harry Landers explores the unknown history of one of Portland’s premier attractions: the International Rose Test Garden. The Garden serves as a trial ground for new rose varieties, as well as an exhibition space. It is the oldest continuously operating public rose test garden in the United States, covering 4.5 acres, and is home to more than 10,000 individual rose plants and approximately 650 varieties. Harry will tell us about the garden and what it takes to make it a World Class Garden and show piece of Portland.

Leach Botanical Garden Plants and History – David Porter, Director of the Leach Botanical Garden www.leachgarden.org
A lush oasis just south of Foster on SE 122nd, the historic Manor House and grounds of Leach Botanical Garden lie in a hollow carved out by Johnson Creek. In 1931 John and Lilla Leach purchased five acres along Johnson Creek and named it “Sleepy Hollow”. Here they built their home and devoted themselves to their love for plants. The original Leach collection, which includes Kalmiopsis leachiana – one of five plant species discovered by botanist Lilla Leach, forms the core of the now 16+ acre botanic garden. Leach Botanical Garden, a model of sustainable and natural landscaping, is dedicated to the conservation of and education about northwest native plants. David Porter will talk about the lives of John and Lilla Leach and the importance of this beautiful garden to gardeners everywhere.
David Porter has a wealth of experience in non-profit management, having served as the Executive Director of organizations as diverse as Pioneer Courthouse Square and the End of the Oregon Trail Interpretive Center. David has a special appreciation for the importance of irreplaceable collections and the opportunities they create: “The stories, whether of John and Lilla Leach or of the plants in the collection, make it possible to spark the imagination and create insights and dialogues on a wide array of topics, connecting our past and our future with the natural world around us.”

Lessons from the Hoyt Arboretum – Fall & Winter Flowering Plants – Fred Nilsen, Arboretum Director retired www.hoytarboretum.org
Fred Nilsen spent his career working for the City of Portland Parks and Recreation Bureau, becoming City Arboriculturist in 1986, and managing Hoyt Arboretum and Forest Park. Under Nilsenʼs leadership, Hoyt Arboretum significantly expanded its tree collections. Parks and volunteers crews built miles of trail in Forest Park, Marquam and other natural areas. Hours of work went into removal of invasive species and, together with Friends of Trees volunteers, thousands of trees were planted.
Since retiring, Fred has continued his involvement with Friends of Trees and Leach Botanic Garden. The focus in Fred’s own garden is on collections of Trilliums, Snow Drops, Epimediums, Daphnes and some unique plant specimens.

Environmental Impacts of Wildfires: The Larger Story of the Eagle Creek Fire – John Bailey, PhD. OSU
Join us for a most timely presentation on the environmental impacts of forest fire, to help us better understand what has happened to our beloved Columbia River Gorge and what we might expect to follow. As the work of silviculture (managing growth, composition, and health of the forest) shifts following the Eagle Creek fire, what can we citizens do to more sensitively use our forests? How might we encourage others to do the same? What are the greatest risks in the next few years?
John Bailey worked for six years with the EPA in Corvallis on forest responses to pollution and climate stress. After earning his doctorate in silviculture, he joined the faculty at Northern Arizona University for nine years working in semi-arid ponderosa pine silviculture, fuels management and restoration treatments. John then returned to the OSU College of Forestry in 2006 to continue work on fuels/fire management and ecosystem restoration in drier forest types.

Growing Carnivorous Plants – Jeff Dallas and Jacob Farin www.growcarnivorousplants.com
Of all the plants intriguing to home gardeners, carnivorous plants tend to be among the most misunderstood and frequently killed when we first attempt to grow them. This is sad, because once folks are able to navigate past the misconceptions and myths about them, they can be some of the most interesting and beautiful plants in a garden, particularly here in the Pacific Northwest. In some cases they can actually be easier to grow than typical garden plants. Jeff Dallas, co-owner of Sarracenia Northwest carnivorous plant nursery, will help you get past these misconceptions. Come learn about commonly available species, care, pests and different applications of carnivorous plants in garden and home settings.

Beyond Pinterest: Unlocking the Secrets behind the Pretty Picture – Darcy Daniels, Landscape Designer www.egardengo.com
Who doesn’t love flipping through gorgeous garden images? Whether on Pinterest or Instagram, they’re inspiring, fun and pretty to look at—but ultimately not very helpful. Darcy will help you break the code, giving you the tools to translate the pretty pictures into tangible garden plans using an innovative method that relies on asking the right questions in the right order as you define your site conditions, tease out your garden needs and desires, and evaluate possible plant partners through a descriptive design-oriented lens. The result: an artful, site-specific composition of plants that you’ll love growing. This easy-to-understand, fresh approach to breaking down the sometimes-mysterious act of combining plants will give you the tools to achieve magical, pin-worthy results in your own garden.

Science of Hops and Brewing – Dr. Shaun Townsend, PhD. OSU https://plantbreeding.oregonstate.edu/plantbreeding/research/hops-breeding-program
The Aroma Hop Breeding Program is developing new hop cultivars which are adapted for Oregon growing conditions, with a focus on essential oil quantity and quality. Ultimately, new aroma hop cultivars that appeal to the craft beer industry will be available for Oregon hop growers.
Shaun Townsend is an Assistant Professor and Senior Research in the Hop Breeding and Genetics program at OSU. He works closely with the Food Science and Technology Department to characterize the chemical profile of breeding selections, evaluate new techniques for evaluating the brewing potential of experimental genotypes and explores the role agronomic management might play in essential oil quantity and quality. Shaun also works closely with hop geneticists to identify and adapt new molecular biology technologies to hop breeding.
