The Redwood Sorrel (Oxalis oregana) is the shamrock of the western rainforest — a lush evergreen groundcover whose clover-like leaves carpet the shaded forest floor and famously fold downward within minutes when direct sun strikes them.1

Offered as a bundle of 3 bare-root plants — see the Planting Guide tab for bare-root handling.

NOTE: Bare-root plants arrive dormant (no leaves) and without soil.

Edible & Medicinal Uses

Both the leaves and flowers are edible, raw or cooked, with a bright, tart, lemon-and-green-apple tang. Like spinach, sorrel is best enjoyed as a flavoring in modest amounts rather than by the bowlful, and cooking softens its sharpness. The sorrel is traditionally eaten with dried fish, and the whole plant used in washes for sore joints and inflammation.1, 4

Ornamental Qualities

As a shade groundcover, Redwood Sorrel is hard to beat: a dense, weed-suppressing evergreen mat 4–8 inches tall with fresh shamrock foliage and dainty white-to-pink spring blooms — a natural native alternative to vinca or ivy. It weaves beautifully around Lady Fern, Spreading Wood Fern, Licorice Fern, Salal, and the huckleberries.2

Environment & Culture

Ecology: Redwood Sorrel carpets the cool, moist Douglas-fir and coast-redwood forests of the Pacific coast, from southwestern British Columbia to northern California. So well adapted to shade that it photosynthesizes in as little as 1/200th of full sunlight, it protects its sensitive leaves from bright light by folding them (a movement called nyctinasty), and its spring flowers support native pollinators.1, 2

Culture: A familiar and well-loved forest plant, Redwood Sorrel appears in the food and medicine traditions of Northwest peoples. We offer it with respect for that knowledge and invite support for Indigenous-led restoration through our Charitable Giving page.4

In the Kitchen

Use it as you would French sorrel: scatter the bright, lemony leaves and flowers raw over a green salad or a plate of smoked fish, stir a handful into soups at the last minute, or blitz it into a tangy sorrel pesto. A little goes a long way — its citrusy zip is a garnish, not a bulk green.5 (Growing and harvest details are on the Planting Guide tab.)

Planting Guide: Redwood Sorrel (Oxalis oregana) — Bundle of 3 Bare-root

Tip: Use it as a living mulch under ferns, shrubs, and trees — its dense evergreen mat shades soil, suppresses weeds, and holds moisture where lawn and most groundcovers fail.

When Your Plant Arrives

Open the box promptly. Your plant travels dormant — no leaves and no soil — which is normal and the healthiest way for it to ship. Keep the roots moist and cool, and unwrap them only when you’re ready to plant. Aim to get it into the ground or a pot within a day or two; if you can’t, tuck the roots into damp soil, sawdust, or a bucket of moist material and hold it somewhere cool and out of frost. Don’t let the roots dry out or sit in standing water. If anything looks amiss, please contact customer service within 7 days of delivery and we’ll make it right.

Choosing a Site

Light: Partial to deep shade — avoid direct sun, which scorches the leaves.

Soil: Cool, moist, humus-rich, slightly acidic.

Space: About 12 in; it carpets by rhizome.

Planting Steps

Plant in fall or spring; set crowns at soil level in compost-enriched ground.

Water in and mulch lightly with leaf litter.

Watering & Care

Establishment: Keep consistently moist while establishing.

After establishment: Low-thirst in suitable shade; occasional summer water in dry spells.

Protection

Wildlife: Spring flowers support native pollinators; a butterfly-friendly groundcover.

Note: A native alternative to ivy for carpeting shade under trees.

Harvest Basics

Use: Pinch young leaves and flowers as needed, in small amounts, for a bright, tart, lemon-and-green-apple note in salads and drinks.

Safety: Like spinach and true sorrel, it is high in oxalic acid — enjoy it as a tart flavoring in moderation, not a bulk green (especially if you are prone to kidney stones).
