Our History

The history of the Hardy Plant Society of Oregon started in the 1970’s, when Marvin Black, a Seattle horticulturist, on a gardener’s exploration of England, discovered Great Britain’s Hardy Plant Society. Marvin was impressed with the organization’s possibilities and turned to his gardening friends for support in organizing the first American Hardy Plant Society. In June of 1980, this group sponsored the first Pacific Northwest Hardy Plant Society Study Weekend at Edmonds Community College.

Eventually, a group of Oregonians, tired of traveling to Seattle for garden events, met with Marvin to plan the beginnings of the Hardy Plant Society of Oregon. HPSO has subsequently inspired the development of several other gardening groups. Throughout the years many dedicated volunteers have been responsible for building and continuing the missions of the Hardy Plant Society of Oregon.


Our Mission

The mission of the Hardy Plant Society of Oregon is to encourage interest in herbaceous perennial plants by:

  • Promoting education and understanding of herbaceous perennial plants through workshops, lectures, study weekends, classes, publications, book sales, mentoring, trips and tours.

  • Fostering networks and informal gathering of the membership.

  • Supporting worthwhile community gardening projects.

  • Sponsoring plant and seed sales or exchanges.

  • Encouraging the preservation of special gardens of botanical, horticultural, or historic interest.
