Oxalis oregana

Oregon Oxalis (aka Redwood Sorrel) is a semi-evergreen, highly attractive ground cover ideal for woodland gardens. In shady undergrowth,  its cheerful shamrock-shaped leaves stick around for most of the year, forming delicate carpets reminiscent of fairy tales. Singular small white blooms suspend above the leaves on a slender stalk. 

  • Plant type/canopy layer: deciduous perennial herbaceous plant/ground cover
  • Size at maturity: 8” tall, spreading laterally via rhizomes 
  • Light requirements: part sun/part shade, full shade
  • Moisture requirements: moist to dry soil, well-drained
  • Bloom time: March - September 
  • Growth rate/ease: moderate growth rate, easy to grow
  • Wildlife support: attracts and provides nectar for adult butterflies, bees and other insect pollinators, caterpillar host plant/larval food source
  • Native habitat/range: Common in moist Douglas-fir and coast redwood forests from the western cascades to the coast, from British Columbia south to California. Portland Plant List - yes. 
  • Special features & uses: groundcover, semi-evergreen, woodland garden, pollinator garden, edible. The tangy leaves are eaten by Native Americans in small quantities since they contain mildly toxic oxalic acid.

Gardening with Oregon Oxalis: Oxalis is ideal under conifers and other overstory trees and shrubs and can spread happily in acidic well-drained soils high in organic matter. It pairs well with native ferns, salal, snowberry and countless other shade-loving small shrubs and perennials.
