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!
Enjoyment
Engage with other plant enthusiasts to delight in the diversity of Oregon’s 3600+ beautiful and fascinating native plant species.
Conservation
Join us in our citizen science initiatives, learn to garden with native plants, and advocate with us for protection of species and their ecosystems.

Initiatives
Gardening with Natives
We encourage gardeners and landscapers to grow species native to Oregon by providing guidelines and by supporting development of tools that help you select species to meet your native plant gardening goals.
Protecting Rare
Plants
NPSO supports several citizen science projects involving data collection on rare plants including the Adopt a Rare Plant program and the Citizens Rare Plant Watch.
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.
