Oxalis oregana is a perennial herb with scaly rhizomes that has no leafy stem above ground.
The scapes have one white to pale pink flower that sometimes has red veins in the petals. The leaves are clover-like with 3
heart shaped leaflets and have long petioles, which are brownish and hairy.
The plants contain oxalic acid, which makes them sour and potentially harmful, but they can be eaten.
(from Western Oregon Flora website)
The leaves of Oxalis oregana were eaten by the Cowlitz, Quileute and Quinault peoples. Like spinach,
they contain mildly toxic oxalic acid, which is named after the genus. (from Wikipedia)
