Oxalis (5130)

Oxalis, also called Redwood-Sorrel, is most likely found in areas that are moist and shady. An herb and a member of the Oxalidaceae Family, it grows by Kiosk 08.  Pilchuck Learning Center’s sponsored Western Washington State University SAM Project extinction possibility is slight; abundant, native to Cascadia.  Containing “oxalic acid” they are safe to eat in small quantities as was the practice of the SW Washington and Coastal Indigenous.
