Redwood Sorrel or Oregon Oxalis (Oxalis oregana) is a species of the wood sorrel family, Oxalidaceae, native to moist Douglas-fir and Coast Redwood forests of western North America from southwestern British Columbia, Washington, Oregon, and California.^[1]^[2]

It 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.^[3]

Redwood sorrel photosynthesises at relatively low levels of ambient light (1/200th of full sunlight). When direct sunlight strikes the leaves they fold downwards; when shade returns, the leaves reopen. Taking only a few minutes, this movement is observable to the eye.^[4]

The leaves of Oxalis oregana were eaten by Native Americans, probably in small quantities, since they contain mildly toxic oxalic acid, whence the genus name.^[5]
