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 .

The seed packet indicates they can be seeded in late Summer or early Autumn. I live in Hamilton which I consider to be a cool temperate zone. Can I seed in April? Rana hay

You can buy asparagus peas with the scientific name of Tetragonolobus purpureus from King Seeds in New Zealand (www.kingseeds.co.nz). I assume this is the same thing? I ordered a bunch last week and they were here witnin 3 or 4 days.
