The Hardy Plant Society of Oregon, commonly known as HPSO, is a non-profit volunteer organization for all gardeners: beginning or experienced, amateur or professional. Founded in 1984 the Society currently has over 2,500 members throughout the Pacific Northwest in Oregon, Southwest Washington, and beyond.

Special notice: We are monitoring the Covid-19 epidemic regarding its impact on HPSO activities. At this time, the HPSO office is closed to meetings and visitors. Our Open Gardens program has restarted on an appointment-only basis. Most of our 2021 overseas garden tours are postponed to 2022. With the cancellation of last year's Hortlandia, a virtual site is now active with links to our vendors’ own websites: https://blog.hardyplantsociety.org/hortlandia-2020/
