A cold-hardy, self-seeding salad green that thrives in the cool, low-light conditions that defeat most other crops.
Claytonia perfoliata · also called winter purslane, Indian lettuce

Miner's lettuce fills the hungry gap between late autumn and early spring when few salad crops are productive. Its mild, succulent leaves need no cooking and are ready weeks before standard lettuces can be sown outdoors.
A little history. Native to western North America, where it was documented as a dietary green during the California Gold Rush. The distinctive disc-shaped leaf that encircles the flower stem is a fused pair of stem leaves, a structure unique to this genus.
Aim for 4 inches (10 cm) between plants once thinned. Press seeds lightly onto moist soil — they need light to germinate. Do not cover with soil. Keep surface evenly moist until sprouts appear. Seedlings emerge in 7–14 days.
Water when the top inch of soil feels dry; in cool weather this is typically once or twice a week. Water when leaves look slightly less plump or soil surface is dry to the touch. Aim for about 1 inch per week including rain.
One light feed at sowing; no further feeding needed for a short crop. What to use: rake in a thin layer of compost before sowing; avoid high-nitrogen fertilizers that promote soft, disease-prone growth.
Pinch out any emerging flower stems promptly to extend the harvest window by 1–2 weeks before the plant bolts fully.
It's ready when harvest when the round basal leaves (the broad, spoon-shaped leaves at the base) are 1–2 inches across. The disc-shaped stem leaves signal peak maturity but are still mild at that stage. Cut individual outer leaves or whole rosettes with scissors 1 inch above soil level. Leave the root and inner growing point intact for regrowth. Harvest in the morning when leaves are most turgid.
Refrigerate unwashed in a sealed bag or container lined with a dry paper towel; use within 5 days. Leaves wilt quickly once cut.
Sow every 3 weeks from early fall through late winter for a continuous cut-and-come-again supply. Allow one or two plants to set seed — they will self-sow reliably for future seasons.
In climates with hard winters, cover with a cold frame or row cover (spunbond fabric) to maintain harvestable leaves through freezes. Plants resume growth as soon as temperatures rise above 40 °F (4 °C).
Radish
Radish sends a swelling taproot down while miner's lettuce feeds in the top few inches, so the two rarely compete for water. Radishes also pull out within a month, opening room just as the rosettes broaden.
Spinach
Sown between spinach rows, the low sprawling rosettes shade the soil surface, hold cool-season moisture, and crowd out winter weeds that would otherwise seed in the gaps.
Garlic
Garlic's strong-smelling foliage can help hide tender salad leaves from aphids that locate hosts by scent. The effect is modest, but garlic overwinters on the same schedule and takes no space the greens need.
Cilantro
Let a few cilantro plants bolt (shift from leaf growth to flowering) and the flat flower clusters draw in hoverflies, lacewings, and tiny parasitic wasps whose larvae feed on the aphids that cluster under salad leaves.
Fennel
Fennel roots release substances that stunt most garden vegetables, and a shallow-rooted salad green is easily set back. Give fennel its own corner well away from the bed — its flowers do feed hoverflies and tiny parasitic wasps, so it still earns a place in the garden.
Easy-going — Miner's Lettuce can grow almost anywhere in the rotation without a strict rest.
The pea and bean family, the cabbage family or the tomato family thrive in this ground next season.
A light feeder that takes little from the bed and leaves the surface loose and weed-free, with no major soil-borne disease to pass on. Wait one season before returning purslane-family greens to the same ground. Beans and peas, cabbage-family crops, or tomatoes and peppers all follow well.
Set your garden's location and every window above becomes a real date — then Verdie reminds you when it's time to sow, transplant, water, and pick.
