Iris Demystified: Chad Harris, Mt. Pleasant Iris Farm *Recertification one hour credit.
All plants do better in an environment that suits their needs. Irises are no different. Bearded irises tend to be less demanding in their requirements, but different classes and varieties can need distinct care. Beardless iris, like Siberian and Japanese iris, can vary widely in their growing needs, with Japanese iris being the most demanding.
Specializing in wet-land-loving iris of Asia, Mt. Pleasant Iris Farm also grows other iris species and garden test many newer bearded iris that require less water. Currently he and a handful of hybridizers worldwide are using Iris ensata to create a new iris hybrid that is longer blooming and more tolerant of cultural needs.
Chad Harris of Mt. Pleasant Iris Farm has been growing many different species of irises in southwest Washington for over 30 years. He is respected in the iris world as a Master Judge with the American Iris Society and for his work with Iris ensata of which several of his introductions hold National Awards. He also enjoys working with the Asian water species Iris laevigata. He also writes articles and gives presentations on Japanese iris judging and culture.

Perennial Combinations: Tom Fischer, Timber Press
Every gardener wants to create breathtaking designs with color, form and texture. But perennial combinations present challenges: How do I know all plants will bloom at the same time? How do I pick plants that have interest in each season? Most perplexing – which plants look good together in the first place?
Tom Fischer will shed light on this topic, drawing ideas from his book, Perennial Companions, and local gardens. In addition, Tom will highlight outstanding plants that are good "mixers".
New gardeners will learn how to create simple pairings with two plants, and gardeners with a bit more experience will find complex arrangements with four or more plants. Whether you want to create a small-scale sanctuary, a welcoming path, or a bewitching border, you’ll find an abundance of inspiration in this talk.
Tom is an editor of a publishing company of horticultural and other books. His talks are always delightful, with great information, and illustrated with vivid images.

The Mystery of Terroir in Oregon – the Relationship of Geology, Soils, and Climate to Wine
Dr. Scott Burns, Professor Emeritus of Geology & Past-Chair of the Dept. of Geology at Portland State University *Recertification one hour credit.
Wines differ from each other based on seven different factors: the type of grape; the bedrock geology and resulting soils; the climate; the soil hydrology; the physiography of the site; the wine maker; and the vineyard management techniques.
The first five of these factors make up what the French call terroir, “the taste of the place”. Bedrocks weather into soils which then liberate chemical nutrients to the grape vines. Twelve of the sixteen essential elements for wine grapes come from the soil. All around the world the geology and soils make up an important component of the terroir of the wine.
Using examples from the Willamette Valley of Oregon, terroir of the region will be discussed because it is strongly influenced by the bedrock geology and soils.
Dr. Burns has been teaching for 44 years, with past positions in Switzerland, New Zealand, Washington, Colorado and Louisiana. Scott specializes in environmental and engineering geology, geomorphology, soils, terroir and Quaternary geology.

Birdening - Attracting Birds to the Garden: Linda Beutler
Wild birds are your best ally when establishing an organic garden, whether for edibles or ornamentals. Birds need food, water, shelter, and cover. This talk will provide suggestions for meeting the necessities of a wide variety of birds.
Linda Beutler is a fearless gardener who grows a great number of plants on a simple, flat 50' x 100' city lot in the Sellwood neighborhood of Portland, Oregon. She was a professional florist for over 20 years, and her first love in her own garden was growing flowers and foliage for cutting. Linda has been an instructor of horticulture at Clackamas Community College for 16 years. Her classes include Herbaceous Perennials (summer term) and The Flower Arranger's Garden I & II (autumn and spring terms). Linda is the author of two books, Gardening with Clematis (Timber Press 2004) and Garden to Vase (Timber Press 2007), both now sadly out-of-print.
