Mache

The hardiest salad green there is - small, mild, nutty rosettes that shrug off single-digit cold and give you fresh salad in January. Sow it in late summer, not spring, and let it seed itself into a permanent patch.

Direct-sow thickly from late summer into autumn, a quarter inch deep and covered - it wants cool soil and darkness to germinate. Get rosettes to 4-6 leaves before hard cold, then harvest all winter.

Mâche is direct-sown, always — the plants are far too small to bother transplanting. Broadcast the seed thickly over a prepared patch, or sow in bands, and cover it about a quarter inch deep and firm it in. Two details matter: mache germinates better in darkness than on the surface, and it germinates better cold than warm. Above roughly 70°F soil it stalls, which is exactly the problem with an August sowing in a hot summer — water the bed to cool it, shade it with a board or burlap until the seedlings appear, and sow in the evening. Give it one to three weeks to come up.

Timing is the whole craft. Sow from about ten weeks before your first frost through to a few weeks after it, in short successions every fortnight. The goal is rosettes with four to six leaves before daylength and cold shut growth down — after that the plants hold rather than grow, and what you have in December is roughly what you will be eating in February. In zones 7 and warmer it needs no protection at all; further north, a low tunnel, cold frame or floating row cover is what keeps the leaves clean, unfrozen and worth picking.

It is undemanding about everything else. Any reasonable, well-drained soil is fine and it needs almost no fertility — a rich bed just makes it bolt sooner. Weed once early, while the seedlings are tiny and losing the race, and then leave it. It grows perfectly well in a window box or a shallow container, and it is a natural for the space a summer crop has just vacated.

Almost none. Weed once while the seedlings are small, cover for clean pickable leaves rather than survival, and keep the winter bed on the dry side - soggy ground is the only thing that kills it.

There is very little to do. Weed once, two or three weeks after sowing, because the seedlings are minute and slow and a flush of chickweed will bury them; after that the cold stops the weeds too. Do not fertilize — mâche neither needs it nor benefits, and lush growth bolts sooner and rots more easily.

A cover is worth putting on, but understand what it is for. The plant does not need protection to survive — it lives through hard freezes uncovered, which is its entire reputation. A low tunnel, cold frame or row cover is about harvest quality: leaves stay clean instead of mud-splashed, unfrozen instead of brittle, and reachable instead of buried under snow. Vent covers on mild days so the air moves.

The single real risk is water sitting around the crowns in cold weather. Mache is not fussy about drainage in the way a Mediterranean herb is, but a waterlogged winter bed will rot the rosettes off at the base and grow gray mold under a closed cover. Water enough to establish the crop in autumn, then let the weather take over, vent your covers, and if your ground is heavy, grow it on a slightly raised bed. Slugs will graze it in a mild wet autumn and are the only pest most gardeners ever see.

Cut the whole rosette just above the crown, keeping it intact - that is how it is served. Cut cleanly and it may push a smaller second rosette. Always harvest thawed, at midday in freezing weather.

Mâche is harvested as a whole rosette, not leaf by leaf — the leaves are too small for that, and the intact little cluster is how it is served on the plate. Slide a sharp knife or a pair of scissors under the rosette and cut just above the growing point at the center. Cut cleanly above the crown and many plants push out a second, smaller rosette a few weeks later; cut below it and that plant is done. Either is fine; with a thickly sown patch most gardeners simply work along the bed and resow.

Harvest when the rosette has eight to twelve leaves and is two or three inches across. Size is the cue, not the calendar — growth nearly stops below 40°F, so a rosette can sit at harvest size for weeks in midwinter without deteriorating. That is what makes it a living larder: you are storing the crop in the ground and cutting what you need.

In freezing weather, wait until the plants have thawed, usually the middle of a sunny day under a cover. Frozen leaves shatter when handled and go limp and dark once they warm up indoors. Cut only what you will eat in the next few days, and keep working along the bed until the rosettes elongate in late winter, which is the end of the season.

Better keeping than most salad greens - about a week refrigerated, dry and unwashed. But the real storage is the garden bed itself, which holds a winter crop far better than a fridge does.

Cut rosettes keep about a week in the crisper, which is good for a salad green — better than lettuce, far better than arugula. Store them dry and unwashed in a container or bag with a paper towel, and wash them just before use; damp mache goes slimy in the same way spinach does.

Washing deserves care rather than speed. The rosettes grow flat on the soil and winter rain splashes grit right into the center, so cut above the crown, then swish them in two or three changes of cold water, lifting them out of the water rather than pouring the water off the top of them. Dry gently — the leaves are tender and bruise in a hard-spun salad spinner.

Mostly, though, do not store it. The whole point of this crop is that the garden is the refrigerator: rosettes hold at harvest size in cold ground for weeks, and cutting a bowlful the evening you want it is both easier and far better than keeping a bag of it. There is no useful way to freeze, dry or preserve mache, and no reason to try.

Mild, sweet, faintly nutty and never bitter - dress it very lightly or you will drown it. The classic French winter salad is mache with beets and walnuts; German cooks serve it with bacon and warm potato.

Mâche is a delicate green with a gentle, nutty, almost buttery flavor and a soft texture, and the one rule is dress it lightly. A heavy vinaigrette flattens it completely. A little walnut or hazelnut oil, a few drops of good vinegar or lemon, salt, and nothing else is the traditional treatment, and it is traditional because it is right. Serve the rosettes whole rather than chopping them — they look like little green flowers on the plate.

The classic is the French winter salad: mâche with roasted or boiled beets, toasted walnuts, and a walnut-oil dressing, sometimes with a crumble of blue cheese or goat cheese. In Germany Feldsalat arrives with warm bacon dressing, croutons and sometimes a soft egg or warm potato, which suits its winter timing perfectly. It also pairs beautifully with citrus segments, apple, pear, smoked fish and cured ham.

Beyond salad it wilts in seconds — stir a handful into a soup at the last moment, fold it through hot pasta or an omelette, or lay it under something warm and let the heat do the work. It does not stand up to real cooking, and there is no point trying to make it. And unlike spinach it is not a high-oxalate green, which makes it a genuinely useful alternative for anyone who has been told to cut back on those.

Unusually rich for a salad leaf: high in vitamin C and beta-carotene, good folate and iron, notable omega-3 fatty acids for a green - and low in oxalates, unlike spinach and chard.

For a plant that looks like nothing much, mâche is nutritionally impressive. It is high in vitamin C — historically that mattered, since it was one of the few fresh greens available in a northern winter — along with beta-carotene (vitamin A), folate, vitamin B6, iron and potassium. It also carries a genuinely notable amount of omega-3 alpha-linolenic acid, which is unusual in a leafy vegetable and one of the reasons it is often singled out among salad greens.

The quiet advantage is what it does not contain much of: oxalate. Spinach, chard, beet greens and purslane are all high-oxalate leaves, which matters to people prone to calcium-oxalate kidney stones and limits how much of their calcium and iron you actually absorb. Mâche is not in that group, so it is a good rotation partner if you eat a lot of spinach, or a straightforward substitute if you have been told to cut back.

Eat it raw, dress it with a little fat so the beta-carotene and vitamin K come along for the ride, and enjoy the fact that the most nutrient-dense thing in the garden in February is also the least trouble.

Nothing came up in August because the soil was too warm. Almost no growth in January is normal. Gritty salad comes from splash - cut above the crown and wash three times. Bolting in spring means the season is over.

Nothing germinated from an August or early-September sowing: the soil was too warm — above about 70°F mache stalls. Cool the bed with water, shade it with a board until seedlings appear, or simply sow two weeks later. Thin, patchy germination: the seed was left uncovered; it germinates better in darkness, so cover it a quarter inch and firm it.

It has barely grown since November: normal and expected. Mache holds rather than grows through the coldest, darkest weeks. Harvest what reached size in autumn, and next year sow two weeks earlier. Frozen solid at breakfast: also normal — wait for the midday thaw before cutting.

The salad is gritty: the rosettes sit on the soil and rain splashes dirt into the crowns. Mulch lightly between plants, cut above the crown rather than at the root, and wash in two or three changes of water, lifting the leaves out rather than pouring off the top. Gray fuzz and collapsing rosettes under a cover: botrytis in still, wet air — vent the cover on mild days and thin crowded patches. Rosettes rotting off at the base in a wet winter: soggy ground; grow the next crop on a raised bed and water less in autumn. Ragged holes and slime trails: slugs in a mild wet spell. Everything stretching and flowering in March: bolting, on schedule — the leaves turn tough, so pull most of it and leave a patch to seed itself for next autumn.

The colder your winter, the more this crop earns its keep. Uncovered down to zone 7, under a cold frame or tunnel from zone 3, and a cool-months-only crop in zones 9-10. Heat is its only enemy.

Mâche is defined by cold tolerance. It survives to around 5°F, and lower still under snow or a cover, which puts it in a class of its own among salad greens.

Zones 3-5: the crop that makes a cold frame worth building. Sow in late summer, get rosettes established before hard cold, and harvest through winter under a frame, low tunnel or thick row cover. Buried under a foot of snow it simply waits. Zones 6-7: sow in early autumn and harvest all winter, with a floating cover mainly to keep the leaves clean. Zones 8-9: an easy outdoor winter crop with no protection at all — sow from October, pick through the mild months, and expect it to bolt in early spring. Zone 10 and warmer: restrict it to the coolest months and accept a short run.

Everywhere, the enemy is heat, at both ends of the crop: warm soil stops the seed germinating and warm days end the harvest by bolting it. That is why spring sowings disappoint almost everywhere, and why in a Mediterranean or Southern climate you treat mache as strictly a winter vegetable. In maritime climates with cool damp winters — the Pacific Northwest, the Northeast coast, northern Europe — it is close to unbeatable, with wet-weather gray mold the only thing to manage.

Let a patch bolt in spring and mache plants itself - volunteers come up on their own each autumn, which is how it has been grown in Europe for centuries. Saved seed keeps four or five years.

Seed saving is almost automatic. As spring warms, some plants stretch up and open sprays of tiny pale blue-white flowers, then set small dry seed. Let a square foot of the patch do this rather than pulling everything for the compost, and either collect the dried stems into a paper bag and thresh them, or simply let the seed drop where it stands. It shatters readily and comes up as a carpet of volunteers the following autumn, all by itself, with better timing than you would have chosen. That self-sown patch is how most of Europe has grown corn salad for centuries, and it is why the plant naturalized across North America in the first place.

Mâche is self-pollinating and there is nothing in a typical garden for it to cross with, so saved seed comes true. Store it dry and cool; it stays viable four or five years. One quirk is worth knowing: very fresh seed can be slow and uneven, and many growers find that seed which has rested for a few months germinates far more evenly — so seed saved in spring is at its best for the autumn sowing, and last year's packet is nothing to apologize for.

If volunteers come up somewhere inconvenient, they transplant surprisingly well while very small, and they hoe out easily. This is a self-seeder that stays polite — it is not aggressive, it does not persist through summer, and unwanted plants are gone with one pass of a hoe.

A weed of European grain fields that became a delicacy - which is exactly what 'corn salad' means. Gathered wild for centuries, cultivated from the 1600s, and still a serious winter crop in France and Germany.

The English names give away the whole history. Corn salad means salad from the corn field — ‘corn’ in the old English sense of grain — because Valerianella locusta grew as a weed among wheat and rye, and country people gathered it in winter and early spring when nothing else green was available. Lamb's lettuce comes from its appearing at lambing time, in the same lean part of the year.

It moved from foraged weed to garden vegetable in France and Germany around the seventeenth century, and it never lost its foothold there. France still grows it commercially at scale — the Nantes region produces most of Europe's supply and treats it as a serious winter crop — and in Germany Feldsalat is a fixture of the winter table. Thomas Jefferson grew it at Monticello, and it appears in early American seed lists.

In the United States it then quietly slipped out of the vegetable garden and into the ditches, where it naturalized widely, and for most of the twentieth century it was better known to American botanists than to American cooks. It came back through French cuisine and the salad-mix trade in the 1980s and 90s, usually under its French name. For a home gardener it remains one of the best-value crops there is: it occupies the bed when nothing else will, needs no attention, and re-sows itself.
