Calystegia silvatica

The morning glory Calystegia silvatica (syn. Calystegia sepium silvatica, C. inflata, and C. sylvestris) is known by the common name giant bindweed or large bindweed. It is the largest species of bindweed and is a strong rampant climber. It is native to southern Europe but has been introduced to many other areas because it is an attractive garden plant. Calystegia silvatica subsp. fraterniflora (Mack. & Bush) Brummitt (short-stalked false bindweed) is native to North America.It has large, arrow-shaped leaves and showy white trumpet-shaped flowers up to 9 centimeters in diameter. It is considered a weed in some areas where it has escaped cultivation and now grows wild. It spreads easily via hardy rhizomes. There are several subspecies.

🌳 Large bindweed is a common and widespread garden weed, recognized for its climbing growth habit. This vine often smothers the plants it climbs on for support, so it's best to remove it as soon as you notice it. However, some gardeners, particularly those who manage wildlife or native gardens, allow large bindweed to grow because of its large, white, and decorative funnel-shaped flowers. It can also be trained to grow over support structures like wire fences.
