Convolvulus arvensis (field bindweed) is a species of bindweed that is rhizomatous and is in the morning glory family (Convolvulaceae), native to Europe and Asia. It is a climbing or creeping herbaceous perennial plant growing to 0.5–2 m high. There are two varieties:

  • Convolvulus arvensis var. arvensis. Leaves broader.
  • Convolvulus arvensis var. linearifolius. Leaves narrower.

Other common names, mostly obsolete, include lesser bindweed, European bindweed, withy wind (in basket willow crops), perennial morning glory, small-flowered morning glory, creeping jenny, and possession vine.


The leaves are spirally arranged, linear to arrowhead-shaped, 2–5 cm long and alternate, with a 1–3 cm petiole. The flowers are trumpet-shaped, 1–2.5 cm diameter, white or pale pink, with five slightly darker pink radial stripes. Flowering occurs in the mid-summer, when white to pale pink, funnel-shaped flowers develop. Flowers are approximately 0.75–1 in (1.9–2.5 cm) across and are subtended by small bracts. Fruit are light brown, rounded and 0.125 inches (3.2 mm) wide. Each fruit contains 2 seeds that are eaten by birds and can remain viable in the soil for decades. The stems climb by twisting around other plant stems in a counterclockwise direction.

Although it produces attractive flowers, it is often unwelcome in gardens as a nuisance weed due to its rapid growth and choking of cultivated plants. It was most likely introduced into North America as a contaminant in crop seed as early as 1739, as an invasive species. Plants typically inhabit roadsides, grasslands and also along streams. Its dense mats invade agricultural fields and reduce crop yields; it is estimated that crop losses due to this plant in the United States exceeded US$377 million in the year 1998 alone.

In one of the tales collected by Jacob and Wilhelm Grimm, Our Lady's Little Glass, this flower is used by Mary, mother of Jesus, to drink wine with when she helps free a wagoner's cart. The story goes on to say that "the little flower is still always called Our Lady's Little Glass."

Ecological impacts

Field bindweed intertwines and topples native species. It competes with other species for sunlight, moisture and nutrients. It poses threats to restoration efforts and riparian corridors by choking out grasses and forbs. It can decrease habitat biodiversity and is one of the most serious weeds of agricultural fields in temperate regions of the world.


Bindweed contains several alkaloids, including pseudotropine, and lesser amounts of tropine, tropinone, and meso-cuscohygrine.

Control and management

Bindweed is difficult to eliminate. Roots may extend as far as nine feet deep, according to one source, or 30 feet, according to another. New plants may sprout from seeds that are up to 20 years old. New plants can also form from root runners and root fragments.

Methods for controlling bindweed include:

  • Physical removal: Bindweed can be controlled by pulling it out by hand or plowing it up every three weeks for up to seven years.
  • Mulching: Applying a barrier to block sun may control bindweed. Black plastic, landscape fabric or cardboard covered with a layer of mulch will prevent light from reaching the bindweed. The light-blocking material must be maintained for up to five years. Plants that emerge on the edges of the covered area must be removed.
  • Biological control: Some insects and mites can eat, distort or stunt bindweed, but do not fully control it.
