Convolvulus arvensis

Warning: this plant is moderately invasive in Toronto.

[Photo: Convolvulus arvensis.]Convolvulus arvensis, known in English as "field bindweed" and in French as liseron des champs, is a perennial native to Eurasia which is now found throughout most of North America. The flowers are white, turning pink with age, and show a clear resemblance to their cousins the morning glories (e.g. Ipomoea purpurea, Ipomoea tricolor).

According to Invasive Exotic Species Ranking for Southern Ontario, field bindweed is moderately invasive here. A native which looks similar, only with larger, showier flowers, is hedge false bindweed (Calystegia sepium).

I photographed this plant in Almonte, Ontario.
