Description
The spargelbean (*Lotus tetragonolobus*) is a low‑growing legume that produces striking dark‑red flowers and distinctive, winged, square pods. Native to the Mediterranean, it thrives in a warm, sunny spot in the garden or in containers. When harvested young, the pods have a mild, nutty flavor reminiscent of a blend of sugar snap pea and green asparagus.
Care instructions
Spargelbeans prefer full sun and a warm climate with well‑drained, loamy soil. Sow directly in the garden from mid‑May (week 20) once night frosts have passed; the plant is frost‑sensitive. Keep the soil consistently moist but avoid waterlogging, especially during flowering and pod development. Harvest the pods young and tender, about 2–3 cm long, to encourage continued production over several weeks. A light mulch of straw or shredded leaves can help the trailing plant spread without touching the soil.
