About The Hardy Plant Society of Oregon
The mission of the Hardy Plant Society of Oregon is to nurture the gardening community. Our vision is to make the world a better place through horticulture.
The Hardy Plant Society of Oregon (HPSO) is a membership organization for gardeners at all levels. Founded in 1984 to serve Oregon and Southwest Washington, the Society now has over 2500 members throughout the Pacific Northwest and beyond.
What we do
Organized to foster an understanding of herbaceous perennial plants (or "hardy perennials"), HPSO now promotes education about a wide range of plants, garden design, and gardening techniques. We sponsor workshops, lectures, study weekends, classes, publications, book sales, plant and garden art sales, trips and tours. We organize member gatherings and encourage member networking, support worthwhile community gardening projects through grants, sponsor plant and seed sales or exchanges, and encourage the preservation of special gardens of botanical, horticultural, or historic interest.
HPSO is a tax-exempt, 501c(3), non-profit, charitable and educational organization, incorporated under the laws of the State of Oregon and governed by a Board of Directors elected by the Society's members.
