Western Regional Plant Introduction Station

The Palouse Region

The Palouse Region

Station facilities are located on the campus of Washington State University (WSU) in Pullman, Washington and on a farm at Central Ferry, Washington. This part of eastern Washington is called the Palouse, a region of extremely rich soil that is extensively farmed. The Palouse is composed of hills created by glacial soil blown in from the west by prevailing winds.
