Yardlong bean seeds — climbing beans up to a metre long

Yardlong beans, also called asparagus beans or snake beans, are vigorous climbers that produce astonishingly long, slender, tender pods — often 40–60 cm and sometimes longer. Their botanical home is Vigna sesquipedalis, and they sit among our legumes within the wider vegetable seeds range. New to beans? Our vegetable growing guide walks you through the essentials.

A heat-loving staple of Asian cooking, they crop heavily through summer and are best picked young and pencil-slim.

Why grow yardlong beans

They bring something different to the bean patch: a warm-climate cousin of the cowpea with a distinctive, nutty flavour and a wonderful crunch in stir-fries. Productive and ornamental on their climbing frames, they're a fun and unusual addition to our legume range, alongside familiar climbing beans.

Growing yardlong beans from seed

These are true heat-lovers, so sow indoors in late spring and don't plant out until the weather is reliably warm. Give them a sturdy support to climb, a sunny, sheltered spot and steady moisture, and pick the pods young and often to keep them coming. Our germination guide helps the seed get away, the sowing calendar shows the timing, and botanical detail lives on the Vigna sesquipedalis page.

In cooler climates, grow them in a greenhouse or polytunnel for the warmth they crave and the heaviest crops.

How long do yardlong beans get?
Pods commonly reach 40–60 cm and can grow longer, but they're best harvested young at pencil thickness, when they're most tender. Are yardlong beans the same as green beans?
No — they're a climbing relative of the cowpea, more heat-loving than common green beans, with a distinctive nutty flavour and crunch. Do yardlong beans need a lot of heat?
Yes. They're true warm-season plants, so sow indoors and plant out only once it's reliably warm; in cool climates grow them under cover. How do I cook yardlong beans?
They're excellent stir-fried, which keeps their crunch, and also good steamed, braised or in curries. Pick them young for the best texture.
