Trillium (Trillium ovatum) by Richard Droker

Welcome to the Central Puget Sound Chapter (CPS) of the Washington Native Plant Society!

We serve King County and the southern half of Snohomish County, encompassing native forests, alpine areas, wetlands, coastal areas, streams and a booming population.  For numerous ways to discover and protect native plants and their habitats close to home, see below. Whether your interest is in learning all you can about native plants and botany, taking care of native plant habitats at home and beyond, or meeting others who are equally passionate about native plants, the CPS chapter has many ways for you to meet your goals.  Please explore our website, and do not hesitate to contact any of our board members if you would like to jump in or have questions.
