Asparagus Pea

Asparagus pea (Lotus tetragonolobus) is a low-growing annual legume native to the Mediterranean. It produces a profusion of striking deep-red flowers followed by uniquely four-winged seed pods. The young pods have a mild, pea-like flavour and a tender texture when harvested small. It thrives in full sun with warm soil.

Growing

Direct sow 2–3 cm deep outdoors once the soil has reached 15 °C. For an earlier crop, start seeds indoors 4 weeks before transplanting, sowing 2–3 cm deep in individual pots. Space plants 30–40 cm apart within rows and keep rows 40–60 cm apart. Germination takes 5–14 days; outdoor germination may take slightly longer than indoors.

Care

Water regularly to keep soil evenly moist but not waterlogged. Being a legume, asparagus pea fixes its own nitrogen and requires little supplemental feeding. Remove weeds early as the low-growing habit means plants can be outcompeted. No staking is necessary. Consistent picking of young pods encourages continued flowering and pod set.

Harvest

Harvest pods when they are no longer than 4 cm — ideally at 2–3 cm — for the best flavour and texture. Pods that are allowed to grow beyond 4 cm become tough and unpleasant to eat. Check plants daily once pod set begins, as pods reach optimum size quickly.

In the kitchen

Steam or stir-fry the young pods briefly — 2–3 minutes is sufficient. They pair well with butter, garlic, and light Asian-style seasonings. Use them whole in the same way as sugar snap peas or mangetout. The mild flavour complements both simple and complex dishes without overpowering other ingredients.

Storing

Use freshly harvested pods within 1–2 days for best quality. Store unwashed in the refrigerator in a paper bag or perforated container for up to 3 days. For longer storage, blanch and freeze: pods keep well for up to 6 months in the freezer.
