Heritage Crops

Celtuce

Lactuca sativa var. angustata

A lettuce grown for a thick, crisp edible stem as well as its leaves — crunchy, mild and completely unlike the supermarket lettuce most people know.

This plant is currently awaiting restock.
LifecycleAnnual vegetable; best grown as a spring to early-summer crop in the UK
PositionFull sun to light partial shade; some afternoon shade can help in warm weather
SoilFertile, moisture-retentive but well-drained soil enriched with compost. Consistent moisture helps produce a thick, tender stem rather than a tough, stressed one.
Garden sizeUsually 30–60 cm tall; allow roughly 25–30 cm between plants so the stem can thicken
ContainerSuitable for containers; use a pot at least 25–30 cm deep and wide for one well-grown plant
Historic eras—
Worth knowing: Like other lettuces, older plants become increasingly bitter and latex-rich as they bolt; harvest stems while still tender.

Why it belongs in a forgotten garden

Celtuce — the story

Why grow it?

One plant gives two genuinely useful harvests: tender leaves first, then a thick crisp stem that looks unusual enough to start a conversation and cooks like a vegetable in its own right.

History & context

Stem lettuce has a long culinary history in East Asia, especially China, where both the leafy tops and thick stems are used as vegetables. It belongs to the same species as ordinary lettuce, but generations of selection produced a crop built around the stem rather than the head.

Growing guide

How to grow Celtuce

Soil & position

Fertile, moisture-retentive but well-drained soil enriched with compost. Consistent moisture helps produce a thick, tender stem rather than a tough, stressed one.

Light: Full sun to light partial shade; some afternoon shade can help in warm weather

Water

Water regularly, especially in containers and dry spring weather. Avoid repeated drought followed by heavy watering.

Propagation

Grow from seed. Sow in spring at about 0.5 cm deep, either in modules or directly once conditions are suitable. Transplant carefully and keep growth moving without long checks.

Sowing referenceSow Apr–MayDepth: 0.5 cm • Cold treatment: No

Ongoing care

Keep weed-free, maintain even moisture and give each plant enough room to build a thick stem. Harvest before a flower stalk begins to extend strongly.

From garden to kitchen

Harvesting & eating it

When to harvest

Young leaves can be taken within the first part of the season; harvest the main stem once it is well thickened but still tender, before obvious bolting.

Outer leaves can be picked while young. For the main crop, harvest the thick central stem before the plant bolts and becomes fibrous. Strip the leaves, peel away the tougher outer skin and use the pale crisp centre.

What is edible?

Young leaves and the peeled central stem.

Flavour & cooking

The peeled stem can be sliced raw into salads, cut into batons for pickling, or quickly stir-fried so it keeps some crunch. Young leaves can be used much like lettuce or cooked greens.

Food value

The stem is crisp, water-rich and low in calories, with fibre and useful micronutrients. Extension literature on stem lettuce highlights vitamin C together with potassium and magnesium as notable components.

Traditional medicinal uses, where mentioned in the historical material, are included as history rather than medical advice.

Kitchen history

Garlic, sesame & celtuce stir-fry

A quick stir-fry keeps the stem crisp and lets its mild flavour carry stronger seasonings.

Celtuce is best known as a stem vegetable in Chinese cooking, where the stem and leafy portion may be treated as separate vegetables.

You’ll need

  • 2 thick celtuce stems
  • 2 spring onions, sliced
  • 1 garlic clove, finely chopped
  • 1 tsp sesame oil
  • 1 tbsp neutral cooking oil
  • 1 tbsp light soy sauce
  • 1 tsp rice vinegar
  • 1 tsp toasted sesame seeds

Method

  1. Strip the leaves from the celtuce, peel the tough outer skin from the stems and slice the tender centres into thin batons.
  2. Heat the neutral oil in a wide frying pan or wok and stir-fry the celtuce for 2–3 minutes.
  3. Add the garlic and spring onion and cook for another minute.
  4. Add the soy sauce and rice vinegar, toss briefly, then remove from the heat.
  5. Finish with sesame oil and toasted sesame seeds.

How tough is it?

Resilience, pests & garden value

Resilience

Easy to grow in the same broad conditions as lettuce, but steady growth matters. Drought, crowding or prolonged heat can push plants toward bolting before the stem reaches its best size.

Pests & practical problems

The main practical problem is bolting: heat, drought or delayed harvest can turn the stem hollow, fibrous or bitter. Slugs, snails and aphids are the most likely routine pests.

Wildlife value

If allowed to flower, the small lettuce-type flowers can be visited by insects, although most plants are harvested before flowering.

Growing in a container

Suitable for containers; use a pot at least 25–30 cm deep and wide for one well-grown plant

Container plants generally need more frequent watering and feeding than the same plant in open ground.
