Polygonum convolvulus - L.

Common Name Black Bindweed
Family Polygonaceae
USDA hardiness Coming soon
Known Hazards Although no specific mention has been made for this species, there have been reports that some members of this genus can cause photosensitivity in susceptible people. Many species also contain oxalic acid (the distinctive lemony flavour of sorrel) - whilst not toxic this substance can bind up other minerals making them unavailable to the body and leading to mineral deficiency. Having said that, a number of common foods such as sorrel and rhubarb contain oxalic acid and the leaves of most members of this genus are nutritious and beneficial to eat in moderate quantities. Cooking the leaves will reduce their content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[238].
Habitats Waste places, arable land and gardens[17].
Range Europe, including Britain, from Norway south and east to N. Africa and temperate Asia.

Edible Uses

Edible Parts: Seed
Edible Uses:

Seed - ground into a powder and used as a gruel or mixed with cereals[207]. The seed coat should be removed before use, this has caused mechanical injury to the digestive systems of animals who have eaten the seed[4]. The seed is rather small and fiddly to utilize.

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

Succeeds in an ordinary garden soil[1] but prefers a moisture retentive not too fertile soil in sun or part shade[200]. A scrambling climbing plant[207], it is often a troublesome weed of agricultural fields[4]. Plants seem to be immune to the predations of rabbits[233].
