C. arvensis is a herbaceous perennial growing from a very deep root system. Shoots develop from adventitious buds on the deep root system at almost any depth down to 1 m. Above ground, the stems trail or climb by twining. Stems slender, to 1.5 m long, twining anticlockwise, glabrous or finely pubescent. Leaves alternate, petiolate, variable in shape, lanceolate or ovate to narrow-oblong, 1.2-5.0 cm long, acute at the apex, entire but often hastate-sagittate at the base, glabrous or pubescent with scattered crisped hairs. Flowers axillary, solitary or in cymes 2-3 on peduncles subequal to the subtending leaf;bracteoles linear, 2-4 mm long. Sepals free, obtuse, 2.5-4.5 mm long. Corolla funnel-shaped, pentamerous with 5 radial pubescent bands but not divided into distinct lobes, 10-25 mm long, 10-25 mm diameter, white or pink. Stamens 5, inserted on corolla tube. Style single with two oblong stigmas. Ovary two-celled. Fruit a capsule, globular to ovoid with a persistent style base, breaking open irregularly. Seeds usually 4, compressed-globose, 3-5 mm diameter;testa granular, dark-brown or black.

Impact

C. arvensis, commonly known as bindweed, is a climbing herbaceous perennial native to Eurasia. This species is present in most parts of the world where it has been accidentally introduced as a contaminant of both agricultural and horticultural seed. C. arvensis produces a long lived root system and up to 500 seeds per plant. This species can grow very rapidly where it competes with native vegetation and agricultural and horticultural crops for nutrients, moisture, light and space. As a result, neighbouring plants may become smothered leading to a decrease in biodiversity and a reduction in crop yield. Control of this species is difficult due to the longevity of seeds in the soil bank (up to 20 years) and the ability of small fragments of rhizome to produce new shoots.

Hosts


Annual crops such as cereals and grain legumes are particularly susceptible, and it is also widely reported as a troublesome weed in vineyards. Holm et al. (1977) also list C. arvensis as a weed of sugarbeet, cotton, tobacco, tea, potato, orchards, pineapples, vegetables, flax and lucerne.
