- Convolvulus arvensis is a perennial vine. It is weak-stemmed and prostrate. Stems twine and can grow to 5 ft. (1.5 m) or longer. C. arvensis has deep, spreading roots and rhizomes. It is native to Africa, temperate and tropical Asia and Europe.
- Leaves are round to arrow-shaped, 1-2.25 in. (2.5-5.7 cm) long, and alternate.
- 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 0.13 in. (0.3 cm) wide. Each fruit contains two seeds.
- Ecological Threat
- C. arvensis most likely was introduced in North America as a contaminant in crop seed as early as 1739. Plants typically inhabit roadsides and grasslands and live along streams.
