renouée grimpante

Climbing Bindweed, Calystegia sepium or related Convolvulus species in the family Convolvulaceae, is a vigorous twining perennial vine native to temperate regions of Europe, Asia, and North America, widely naturalized in disturbed habitats worldwide. The species climbs over hedgerows, fences, tall herbs, and shrubs by twining its flexible stems counterclockwise around supporting structures, sometimes smothering vegetation under dense leafy growth. The leaves are broadly arrow-shaped or hastate, and the funnel-shaped flowers are large, white to pale pink, and open during daylight hours. Like its relatives, Climbing Bindweed has deeply buried, extensively spreading rhizomes that are extremely difficult to eradicate once established. The extensive root system enables survival of herbicide treatments and mechanical disturbance, making the species a persistent weed in gardens, agricultural land, and riparian habitats. Despite its weedy character, the flowers provide nectar for bumblebees and are visited by hawk moths at dusk. The species is not threatened globally; it is considered common and often invasive across temperate regions. It has considerable cultural significance, appearing frequently in art and folklore as a symbol of persistence and entanglement.
