Meet Miner's Lettuce
A native North American green eaten by Gold Rush miners to prevent scurvy, producing round leaves and tiny white flowers. Plants prefer cool, moist shade and naturalize easily in Pacific Northwest and similar maritime climates. One of the best winter salad greens for mild climates, staying productive from fall through spring. Slightly succulent leaves have a mild, clean flavor excellent in fresh salads.
When to plant Miner's Lettuce
Sow seeds on the surface of moist soil in early spring or late summer. Press gently without covering as seeds need light and cool temperatures of 40 to 55 degrees to germinate. Stratify seeds in the refrigerator for 2 weeks in damp paper towel to improve germination. Germination takes 10 to 21 days and can be erratic. Self-sown plants are often more vigorous than hand-sown ones.

Used once to set your season · never sharedHow to grow Miner's Lettuce
Miner's lettuce, or claytonia, is a delicate wild green native to western North America, named for its use by Gold Rush miners to prevent scurvy. Direct sow seeds on the surface of moist soil in early spring or late summer. Press seeds gently without covering, as they need light and cool temperatures to germinate. Seeds germinate best at 40 to 55 degrees Fahrenheit over 10 to 21 days.
Miner's lettuce thrives in cool, moist, shady conditions that challenge most other salad greens. It is an excellent crop for partially shaded garden areas, under trees, and in north-facing beds. Keep soil consistently moist, as plants wilt rapidly in dry conditions.
Plants self-seed prolifically and often naturalize in favorable locations, returning as a volunteer crop each autumn. In mild climates, it grows through winter. Minimal care is needed once established. No fertilization is required as miner's lettuce evolved in poor soils. Grow as a ground cover in orchard understories and shady garden areas.

Miner's Lettuce's best neighbours
Miner's lettuce makes an excellent ground cover under taller crops, fruit trees, and berry bushes. It thrives in the shade that most other salad greens cannot tolerate. Pair with other shade-loving edibles like ferns and woodruff. Avoid planting in full sun during summer. It naturalizes well in woodland garden settings.
It flags clashes before you plant, not after
Every plant you place is checked against its neighbours in real time. Good matches glow green; conflicts get flagged on the spot — so a season-wrecking mistake never makes it into the ground.
Feed it well
Miner's lettuce grows naturally in poor to moderate soil and needs no fertilization. It prefers moist, well-drained soil with a pH between 6.0 and 7.0. A light top-dressing of compost in autumn helps overwintering plants. Rich soil produces lush but floppy growth. Container plants need a light potting mix with minimal added fertilizer.

Hardiness Zone Compatibility
From seed to harvest, stage by stage
Seed Germination
Tiny black seeds germinate in cool, moist soil between 5-12°C (41-54°F). The seeds require a period of cold stratification or consistently cool temperatures to break dormancy. Thin, grass-like cotyledons emerge first, easily mistaken for weeds by unfamiliar gardeners.
Basal Rosette
The plant develops a low rosette of spoon-shaped to diamond-shaped basal leaves on long, slender petioles. These early leaves are tender and mild, excellent for baby green harvests. Growth is steady in cool weather, forming a compact mound 5-10 cm across.
Perfoliate Leaf Stage
The plant's signature feature appears — round, disc-shaped leaves (perfoliate leaves) form where the stem appears to grow directly through the center of the leaf blade. These distinctive lily-pad-like discs are the hallmark of miner's lettuce and the prime harvest stage for salad use.
Flowering
Small clusters of tiny white to pink flowers emerge from the center of each disc leaf, creating a charming miniature bouquet effect. Flowers are edible and mildly sweet. The plant begins to stretch upward and leaf flavor may develop a slight mineral tang.
Seed Set and Decline
After pollination, tiny shiny black seeds develop and drop freely around the parent plant. Leaves become smaller and tougher as the plant puts all energy into reproduction. In warm weather above 22°C (72°F), the plant yellows and dies back naturally, completing its annual lifecycle.
Refrigerate seeds for 2 weeks before sowing to simulate winter stratification. Surface-sow or barely cover with 3mm of fine soil — seeds need some light to germinate. Keep soil consistently moist but never waterlogged.
Caring for Miner's Lettuce month by month
What to do each month for your Miner's Lettuce
July
You are hereThe plant is dormant as seed in most climates. Store collected seeds in a cool, dry place. Plan shady growing areas for autumn sowing. This is a good time to improve beds with compost and establish shade structures for next season's crop.
Harvesting Miner's Lettuce
Harvest miner's lettuce when the distinctive round disc-shaped leaves are fully developed, about 40 to 50 days after sowing. Cut entire plants at the base or pick individual leaves and stems. The whole plant including tiny white flowers is edible. For cut-and-come-again production, cut back to 1 inch above soil level. Flavor is mildest in cool weather and partial shade.

Storage & Preservation
Miner's lettuce is very perishable, lasting only 2 to 3 days in the refrigerator. Store in a sealed container with damp paper towel. It does not freeze or dry well due to its delicate, succulent nature. The best preservation strategy is to encourage self-seeding for a naturalized, year-round fresh supply rather than attempting to store the fragile leaves.
What goes wrong — and the fix
Slugs
PestHoles in the succulent round leaves and slimy trails, damage worst in cool damp weather.
Aphids
PestSmall insects on stems and leaf undersides, most common in sheltered growing areas.
Rust
DiseaseOrange-brown pustules on undersides of leaves, usually in warm humid conditions.
Troubleshooting Common Problems
Germination can be unreliable without cool temperatures and light exposure. Plants collapse in hot, dry weather and do not tolerate summer heat. In very rich soil, growth becomes overly lush and prone to rot. Self-seeding can be invasive in favorable conditions. Slugs are attracted to the succulent leaves in the moist conditions that miner's lettuce prefers.
Growing Tips
- Embrace shade as an advantage, not a limitation. Miner's lettuce genuinely prefers partial to full shade and will scorch and bolt prematurely in direct sun. Plant it under deciduous trees, on north-facing slopes, or against north-facing walls where other crops fail.
- Cold-stratify seeds for the best germination. Store seeds in a damp paper towel inside a sealed bag in the refrigerator for 2 weeks before sowing. Without this cold treatment, germination can be sporadic and frustratingly slow.
- Sow seeds on the surface and press gently — do not bury them. Miner's lettuce seeds are tiny and need some light to trigger germination. Simply scatter on moist soil and press with your palm or the back of a rake.
- Water consistently during establishment but avoid overhead irrigation once plants are growing. Miner's lettuce needs steady moisture but its fleshy, succulent leaves are prone to fungal problems in persistently wet conditions. Drip irrigation or gentle ground-level watering is ideal.
- Harvest by cutting entire stems with disc leaves attached rather than picking individual leaves. This gives you the most attractive presentation for salads, encourages new growth from the base, and is far faster than leaf-by-leaf picking.
- Let some plants go to seed every season and resist the urge to clean up completely. Miner's lettuce is a self-sowing champion — seeds that drop in late spring germinate automatically with autumn rains, creating a perennial patch with zero replanting effort year after year.
- Grow miner's lettuce as a living mulch and edible ground cover beneath taller crops. It makes an excellent understory plant beneath tomatoes, peppers, and fruit trees, suppressing weeds, retaining soil moisture, and providing bonus harvests from otherwise wasted space.
- Pair miner's lettuce with your cool-season garden calendar. It fills the gap when warm-season crops are absent — sow in early autumn for winter and spring greens, and let it die back naturally as your tomatoes and squash take over in summer.
Pick your Miner's Lettuce
Claytonia perfoliata
The standard wild type with round leaves pierced by the flowering stem, mild and succulent.
Claytonia sibirica
Siberian spring beauty with larger leaves and pink flowers, more shade-tolerant.
Cuban Spinach
A related species with thicker, more succulent leaves suited to warmer growing conditions.
Miner's lettuce is virtually free once established. A single packet of seeds ($3-5) sows a large patch that self-sows perpetually, producing fresh salad greens every cool season for years with no replanting, fertilizing, or significant watering beyond natural rainfall. With specialty and foraged greens selling for $15-30 per pound at farmers markets and gourmet grocers, a productive self-sowing patch can easily replace $50-150 worth of purchased salad greens per year. Because it grows in shade where nothing else will, it adds food production to garden space that would otherwise be unproductive.

What's inside
Health Benefits
- Exceptionally high in vitamin C for a leafy green — historically proven to prevent and cure scurvy, and providing roughly 33% of the daily value per 100g to support immune function, collagen synthesis, and iron absorption.
- Contains omega-3 fatty acids (alpha-linolenic acid) in unusually high concentrations for a land plant, supporting cardiovascular health, reducing inflammation, and promoting healthy brain function.
- Rich in vitamin A as beta-carotene, providing antioxidant protection for cells and supporting healthy vision, skin integrity, and immune system regulation.
- Provides bioavailable iron paired with its own vitamin C content, which enhances absorption — making it a particularly effective plant source of iron for preventing anemia.
- The mucilaginous quality of the leaves has a soothing effect on the digestive tract, traditionally used by Indigenous peoples to ease stomach complaints and support gentle digestion.
- Very low in oxalates compared to spinach and other dark leafy greens, meaning its calcium and mineral content is more bioavailable and better suited for people prone to kidney stones.
Where Miner's Lettuce comes from
Miner's lettuce (Claytonia perfoliata) is native to western North America, ranging from southern Alaska through British Columbia, down the Pacific Coast to Baja California, and east into the Rocky Mountain states. It grows naturally in moist, shaded habitats — forest understories, stream banks, north-facing slopes, and the edges of meadows from sea level to around 2,400 meters elevation. The plant is a true winter annual, germinating with autumn rains, growing through cool wet months, and completing its lifecycle by early summer as temperatures rise.
Indigenous peoples across western North America harvested miner's lettuce as an important early spring green long before European contact. The Ohlone, Miwok, Chumash, and many other groups ate the leaves, stems, and flowers raw or lightly cooked, and some nations used the plant medicinally. When Spanish missionaries and later Gold Rush settlers arrived in California, they quickly learned the value of this wild green. During the California Gold Rush of 1849, miners working in remote Sierra Nevada camps suffered terribly from scurvy until they discovered that eating large quantities of this abundant local plant — rich in vitamin C — could prevent and even cure the disease. The plant became so closely associated with mining communities that it earned the permanent common name 'miner's lettuce.'
The plant was introduced to Europe in the early 1800s, initially as a botanical curiosity. It quickly escaped cultivation and naturalized in parts of England, Scotland, Ireland, France, and other Western European countries, where it now grows wild in parks, gardens, and woodlands. In recent decades, miner's lettuce has experienced a renaissance among chefs, foragers, and home gardeners who value it as a gourmet salad green, a shade-tolerant edible ground cover, and one of the easiest wild greens to cultivate. It remains largely unknown in mainstream agriculture but is increasingly featured at farmers markets and in restaurant kitchens across North America and Europe.
