Klamath Ruby Redwood Sorrel

Klamath Ruby Redwood Sorrel (Oxalis oregana 'Klamath Ruby') is a striking and vigorous evergreen groundcover native to the coastal forests of the Pacific Northwest. This selection is highly prized for its ornamental value, featuring large, velvety, clover-like leaves that are dark green on top with a brilliant, shimmering burgundy-ruby underside. From spring through fall, the foliage is accented by delicate white-to-pale-pink flowers with elegant pink veining.

As a resilient member of the Oxalis genus, 'Klamath Ruby' is a specialist for the most challenging spots in the garden. It is one of the few plants that truly thrives in deep shade and under the canopy of large trees like Redwoods and Douglas Firs. Its dense, mat-forming habit makes it an excellent weed suppressant and a beautiful "living mulch." One of its most fascinating features is its rapid light response—the leaflets fold downward in bright sun or heavy rain to protect themselves, reopening once conditions soften.

Why you’ll love it:

• Stunning Contrast: Dramatic dark green foliage with deep ruby-red undersides for year-round visual interest.
• Shade Solutions: Thrives in deep, dappled, or partial shade—perfect for woodland gardens and north-facing beds.
• Long Blooming Season: Enjoys a prolific bloom cycle from spring all the way into autumn.
• Wildlife Friendly: Attracts butterflies and pollinators while remaining naturally deer-resistant.
• Tough & Versatile: Tolerates wet conditions, drought once established, and even occasional mowing.

This healthy 4" live flowering plant is a vigorous grower that performs best in moist, organic-rich soil and shaded exposures.
