Neither asparagus nor a pea but it does have pods which are eaten like a 'mangetout' pea and does have a taste reminiscent of asparagus!
Easy to grow producing numerous winged pods which should be picked at about 2.5cm (1in) long and steamed or sautéed whole.
Sow & Grow :
Outdoors: sow thinly, April-June where they are to crop, 2.5cm (1") deep, directly into finely-prepared, fertile, well-drained soil, which has already been watered.
Provide cloche protection or delay sowing if soil is still cold. Allow 30cm (1') between rows. Seedlings usually appear in 7-21 days. Thin seedlings to 45cm (18") apart. Water well until plants are established.
Two or three sowings will provide a successional crop.
Hints & Tips:
Pick regularly to encourage further pods to form. Top and tail and boil whole pods.
