Appearance

"Oxalis oregana" is a short, herbaceous perennial plant with erect flowering stems 5–15 cm tall. The three leaflets are heart-shaped, 1–4.5 cm long with purplish undersides, on 5–20 cm stalks. The inflorescence is 2.4–4 cm in diameter, white to pink with five petals and sepals. The hairy five-chambered seed capsules are egg-shaped, 7–9 mm long; seeds are almond shaped.
Oxalis These lovely little plants are native, but they have also become a fast favorite with shade gardeners (in fact I have some planted along the side of my own house) and are often sold around St. Patrick's day as "Shamrock" house plant. Oxalis is edible, with a slightly sour taste, but don't eat too much, the oxalic acid in them can be toxic in very large doses (same as in rhubarb leaves). The leaves are rather sensitive to the sun and will fold up into little pyramids if they get too hot. Geotagged,Oxalis oregana,United States,Winter

Food

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.
