Larger bindweed is able to grow over four metres (13 feet) high in a single summer. This means it stretches up to 20 cm (8 in.) in 24 hours – during its most intense period it is almost possible to watch the plant grow in front of your eyes. Larger bindweed is able to grow so high by winding itself around other plants or a trellis. Young shoots grope around to find a suitable erect and supportive object or plant. Unlike most other plants, larger bindweed always turns anti-clockwise.

Larger bindweed in Finland likes to use seashore willow, meadowsweet and nettles for support. It is often also cultivated as an ornamental on balconies, porches and around pavilions. On the other hand many people regard larger bindweed as an unwanted guest in the garden whose vigorous energy chokes out other vegetation. Wild, freedom-loving larger bindweed easily runs amok outside the garden too, and the species has achieved its current status in the wild in a relatively short space of time. A pink-flowered species is often found in and around gardens, while the original species is always white-flowered.

Field bindweed (Convolvulus arvensis) follows people too but has clearly smaller flowers. Also dwarf morning glory (Convolvulus tricolor) is a possible species in Finland but only in gardens.
