Oxalis oregana (redwood sorrel, Oregon oxalis, shamrock) at the Butchart Gardens in Brentwood Bay, British Columbia, Canada.
Oxalis oregana (redwood sorrel, Oregon oxalis) 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. Oxalis oregana is a short, herbaceous perennial plant with erect flowering stems 5–15 cm tall. The three leaflets are heart-shaped, 1– cm long with purplish undersides, on 5–20 cm stalks. The inflorescence is –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. Redwood sorrel, Oxalis oregana, 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. *** Description sourced from Wikipedia (2018).
