The redwood sorrel, Oxalis oregana, is a lovely shade ground cover which offers beautiful foliage that often remains evergreen through a mild winter. The cute flowers are white or pale pink. Vigorous, so keep an eye on it or plant it in a drier location. This species is native to BC but is only found in limited locations on the southern tip of the Queen Charlotte Islands and near Barkeley Sound on the west coast of Vancouver Island. It is much more common south of the border and into California where it is an understorey plant in the giant redwood forests. Pollinated by native bees and butterflies. It is a larval host for native butterflies and moths.

Redwood sorrel is a short herbaceous perennial plant with erect flowering stems 5?15 cm tall. The three leaflets are heart-shaped with purplish undersides. The flowers are white to pink and the hairy five-chambered seed capsules are egg-shaped. This oxalis is found in moist Douglas Fir and Coast Redwood forests, blanketing the forest floor with its dense foliage, making it a great understory ground cover. The leaves of Oxalis oregana were eaten by Native Americans, probably in small quantities, since they contain mildly toxic oxalic acid, hence the genus name. Bloom period: February - September Native to California and is also found outside of California, but is confined to western North America. Tiny white flowers attract native bees and butterflies. The leaves were eaten by Native Americans, probably in small quantities, since they contain mildly toxic oxalic acid. Found in widespread on the dark, moist forest floor. Communitites located in Redwood Forest, Douglas-Fir Forest Between 0 and 3280 feet.

A Cistus introduction, collected near Rowdy Creek on the Smith River almost directly on the California/Oregon border. This form of the native redwood sorrel grows to 6-8" in height, the leaves dark green above with deep maroon undersides and the flowers, smallish and pale pink in spring and summer. Works well in the deepest dark, dry shade, or in dappled sun. Happy to go dormant in the summer but remains evergreen with some water. Grows vigorously in winter. Cold hardy in USDA zone 7. An excellent small-scale groundcover.
