Perideridia oregana

Eepah or Yampah is a native perennial in the carrot family that was used as an important food source for first nation people. To 20″ tall 1-3 stems emerge from swollen edible roots  and produce pure white umbels of flowers. All parts of this plant are edible and the roots are high in vitamin c, protein, and Potassium. Eaten fresh it has a juicy crispy texture and taste similar to a water chestnut. Cooking Eepah root yields a nutty flavor with a sweet consistency of sweet potato. The large green seeds have a flavor very similar to Caraway and were eaten fresh or dried. Simple looking perennial that is very similar in appearance to introduced wild carrot or Queen Ann’s Lace Daucus carota.  Oregon Eepah is native from extreme southwest Washington, much more common in Oregon and northern California. It has lost large amounts of its lowland population to invasive weeds and development. Where it occurs much more frequently is at higher elevations where there is less weed competition. Full sun to very light shade in average to rich soil. Irrigate for the first season, in subsequent years it can survive on rainfall alone. Winter deciduous. NEVER EAT A WILD PLANT unless you are 100% certain of its identity, if not ask an expert before consuming any unknown plant. Great plant for butterflies and pollinators. Its wild appearance lends it to cottage gardens, serious vegetable gardens.  Blooms May-july. Its a very pretty cut flower and was once a common component of Willamette Valley meadows (mainly on hillsides).      Oregon native plant
