Convolvulus arvensis (common name: field bindweed)

Propagation: Seed - best sown in situ as soon as it is ripe, it germinates in the autumn[1]. This species can become a real pest in the garden so it is unwise to encourage it.

Cultivation: Prefers a lighter basic soil[2] of low to medium fertility[3].

Bindweed is a very deep-rooting plant with a vigorous root system that extends to a considerable distance and is very hard to eradicate from the soil. Even a small piece of the root will grow into a new plant if it is left in the ground. Once established this plant soon becomes a pernicious weed[4][5]. It is a climbing plant that supports itself by twining around any support it can find and can soon swamp and strangle other plants[5].

The flowers close at night and also during rainy weather[5]. Although visited by numerous insects, the flowers seldom set fertile seed[5]. On sunny days the flowers diffuse a scent of heliotrope[6].

The plant harbours tobacco mosaic virus of the Solanaceae[7] and so should not be grown near potatoes, tomatoes and other members of that family.

Range: Throughout the temperate regions of both Hemishperes, including Britain.

Habitat: Hedgerows, fields, waste places, fences etc[8][9], it can be a troublesome weed of agriculture.

Edibility: The plant has been used as a flavouring in a liqueur called 'Noyeau'[10]. No details are given as to which part of the plant is used[K].

Medicinal: The root, and also a resin made from the root, is cholagogue, diuretic, laxative and strongly purgative[5][7. 9. 13][11]. The dried root contains 4.9% resin[11]. The juice of the root is used in the treatment of fevers[12].

A tea made from the flowers is laxative and is also used in the treatment of fevers and wounds[13].

A cold tea made from the leaves is laxative and is also used as a wash for spider bites or taken internally to reduce excessive menstrual flow[13][14].

Usage: The stem is used as a twine for tying up plants etc[15][16]. It is fairly flexible and strong but not long-lasting.

A green dye is obtained from the whole plant[17].

Pollinators: Bees, flies, self

Soil: Can grow in light and medium soils.

Seed Ripens: Late Summer-Mid Fall

Flower Type: Hermaphrodite
