Enjoying Oregon's native flora
Oregon has over 3600 species of native plants. Large or small, abundant or rare, each is unique and special.
Student of the flora! (N. Jensen)
Ecoregions ranging from coastal sand dunes and mountain forest to prairie grasslands and alpine lava fields provide a myriad of habitats for these plants.
Local chapters hold meetings, field trips, and plant shows and sales for members and non-members alike, making available the knowledge and wonder of our native plants to everyone.
Conservation & preservation
Over 450 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.
Study and education
NPSO, both at the state level and through individual chapters, provides support for research about native plants.
Classes providing information about native plants are given by local chapters.
The NPSO Bulletin and our journal, Kalmiopsis, provide timely and in-depth coverage of issues relating to native plants.
