When can I sow and harvest lamb's lettuce?

Sow August to October for autumn–winter–spring cropping. Don't sow March–July — plants bolt almost immediately in warm weather. Harvest from October through to April, peaking in October–November and again in March–April with slow steady cropping through December–February. Cut whole rosettes at 5–7 cm rather than picking individual leaves.

Will lamb's lettuce survive a UK winter?

Yes — it's one of the hardiest winter salads (RHS H7). Survives normal UK winters in the open, including frost and snow. Frost-rimed leaves taste sweeter. In hard winters (-10°C and below), cover with a cloche or fleece for protection — but most years no protection is needed. Snow cover acts as natural insulation. Lamb's lettuce is one of the few culinary crops that genuinely produces leaves in January and February.

What does lamb's lettuce taste like?

Mild, faintly nutty, with a soft buttery texture. Much less sharp than rocket or watercress; far milder than mustard greens or chicory. The flavour is delicate — pairs well with sharp citrus dressings, sweet beetroot, walnuts, blue cheese, smoked salmon. Classic French use: mâche salad with hot bacon dressing and warm croutons. UK gardeners: think of lamb's lettuce as a less aggressive substitute for rocket through winter when rocket is bolting or absent.

Can I grow lamb's lettuce in pots?

Yes — perfect for pots and windowboxes. A 25 cm pot of peat-free compost holds 10–15 rosettes. Sow in September, water consistently. Pot lamb's lettuce gives the same winter cropping as in-ground plants with the convenience of moving the pot to a sheltered position in hard weather. Three pots in rotation gives continuous winter salad. For a cloche-protected pot: place a glass cloche or inverted plastic bottle over the pot in hard frost.

Is lamb's lettuce the same as corn salad?

Yes — different names, same plant. Lamb's lettuce (UK common name), corn salad (older UK name, traditional), mâche (French name, often used in UK food writing). All three names refer to Valerianella locusta. The corn in corn salad refers to grain fields where the plant naturally self-seeds as a winter annual weed — hence corn in the British sense of cereal grains, not American sweetcorn.

Why do my lamb's lettuce rosettes stay small?

Three usual causes. (1) Wrong season: summer-sown plants bolt before sizing up. Sow August–October only. (2) Crowded planting: thin seedlings to 10 cm; overcrowded plants stay small. (3) Hard winter conditions: rosettes grow slowly in December–February — that's normal. Spring flush (March–April) brings the largest rosettes of the year. Patience is the rule; lamb's lettuce isn't a fast-growing crop.

Mâche

Valerianella locusta

Sow lamb's lettuce direct from August to October, in sun or part shade in well-drained soil — it's a very hardy winter salad green (RHS H7) that fills the gap when most other salads are dormant, cropping through autumn, winter, and into spring. Lamb's lettuce forms small flat rosettes of soft mild oval leaves with a faintly nutty flavour. Outdoors it crops through frost and snow — one of the few salad greens that genuinely produces useable leaves in January and February. Sown in spring it bolts almost immediately in warm weather; this is fundamentally an autumn-winter-spring crop. Cut whole rosettes when leaves are 5–7 cm long — pick individual leaves and the plant disappoints. Self-seeds modestly. Distinct from lettuce (different family entirely).
