  • Space plants: 20 - 25 cm apart
  • Harvest in 8-11 weeks. Pick early, pick often.

  • Pod and flower

This low spreading plant has small trifoliate leaves, and deep crimson flowers are borne in pairs. Harvest pods when approximately 2.5cm (1") long. ( about 80 days) Asparagus pea is easy to cultivate. It needs average moisture, full sun, and ordinary soil. It needs a long growing season to flower and fruit properly, so start it indoors in cooler areas.

Only the pods are edible for Lotus tetragonobolus. The other asparagus pea is the tropical plant Psophocarpus tetragonolobus, also known as Goa bean.

Support with twigs to keep the stems off the ground. Protect from slugs and snails. Pick pods when small as they become hard and dry if left too long.

Culinary hints - cooking and eating Asparagus Pea

Cook quickly by steaming and serve with just a touch of butter and they are said to taste like their namesake .

Will it be possible to obtain a packet of winged been seeds? I have heard about the nutritional value of winged been Regards Prasad

Hi Catherine, I planted 10 seeds early February. Nothing happened for weeks but now most are about 20cms tall. I have to prop them up. My seed packet indicates that no fertiliser is required as it is ‘a very strong nitrogen fixer’ whatever that means. Good luck.

What fertiliser I need to use is blooming now. This is nearly end of autumn. Start to see the bean but quite small. What fertiliser I need to grow bigger bean? First time to see the flower is light blue. How long can it stay in winter ? Let me know. Thank you

I have been harvesting my winged beans at various sizes, and the plant here just out of Darwin has fruited profusely. Unfortunately tho I have not enjoyed them so I have pulled them up to make way for the Borraloolla bean?

Lived Borrolloola for over 2 years and never heard of the Borrolloola pea (heard about a unique cycad from the Loo). Would be interested in trying a Borralloola pea. Do you know where can I get seeds? I live in Wagait Beach

I live in Newcastle and grow winged bean in my garden. It is the second year I tried to grow this plant. First year the plant died in winter but the root is still alive so I continued to grow them last spring. They have some flowers( white/purple) right now and have some fruits already. However, the fruits are very tiny, after two weeks still not much growth. Does it mean the weather in Newcastle is too cold for my winded beans? I got another type of seeds which claims it will flowers in colder climate but need to wait until spring time. Thanks for your time.

I grow winged beans in brisbane and its all set up with drip lines .It's very hot here and dry at the moment and I'm exspiriencing hard dark green beans at the moment. Does anyone know if this is from hot temps or not enough water. Kind Regards Daniel

You will more likely have far better success planting in the early autumn to early spring. Trying to grow things in summer in S E Qld is a hard game in summer(HOT, WINDY, storms) - have a rest and work on building your soil up for March/April planting.

I live in the Adelaide region and my winged bean plant has just completed a massive burst of flowers and crop. This seemed completely out of season as it was planted at least a year ago, barely survived summer without flowering throughout, survived winter without a problem (which seems to contradict its need for higher soil temperatures), then in mid-August took off with growth and flowers. I've just cut it right back so is it possible it will start new growth and survive another season?
