Welcome to all!

Oregonians live in a state with exceptional natural beauty and diversity that ranges from alpine lava fields to coastal sand dunes.

For over 60 years, members of the Native Plant Society of Oregon have been visiting the wild places of Oregon to enjoy, conserve, and study their natural vegetation. Founded in Portland in 1961, NPSO has grown to a statewide network of 11 Chapters with over 1000 members. We invite you to join us!

Exploring Oregon’s Plant Diversity

Help contribute to our knowledge of Oregon’s flora by joining our iNaturalist project, Flora of Oregon: Vascular Plants, a collaboration among OSU Herbarium, OregonFlora, and the NPSO. Learn about our project and read more on how to participate, here!

Call to Action

Over 500 of our native plant species are listed as threatened or endangered by the Oregon Biodiversity Information Center. Native plants provide food and support for wildlife that introduced plants cannot. Conserving and preserving species and habitat for all native species, but especially those in danger is a priority for NPSO.

We Need You

Help us protect our natural diversity and ensure we can offer programs to engage everyone in enjoying and valuing our species and their ecosystems. Become a member to join our community of plant enthusiasts and botanists, or donate to one of our initiatives.
