Oregon Oxalis Redwood
Oxalis oregana
Oxalidaceae · broadleaf · native
You find Oregon Oxalis as a charming groundcover in moist redwood and Douglas-fir forests, with clover-like trifoliate leaves appearing in extensive colonies on the forest floor. The solitary pink or white flowers appear in spring, but this plant is equally appreciated for its attractive foliage. The leaves contain oxalic acid, giving them a pleasant tart flavor.
Oregon Oxalis thrives in moist shaded forest conditions with acidic soil rich in organic matter. This low-maintenance groundcover spreads by rhizomes to form continuous mats. Use as a woodland groundcover or under native trees. Leaves are edible in moderation as a salad green, providing spring nutrients. Once established in appropriate conditions, it requires no supplemental care.
