The most characteristic members of the order are twining plants with generally smooth heart-shaped leaves and large showy white or purple flowers, as, for instance, the greater bindweed of English hedges, Calystegia sepium, and many species of the genus Ipomaea, the largest of the order, including the "convolvulus major" of gardens, and morning glory.
The creeping or trailing type is a common one, as in the English bindweed (Convolvulus arvensis), which has also a tendency to climb, and Calystegia Soldanella, the sea-bindweed, the long creeping stem of which forms a sandbinder on English seashores; a widespread and efficient tropical sand-binder is Ipomaea Pes-Caprae.
Convolvulus arvensis (bindweed) is a pest in fields and gardens on account of its wide-spreading underground stem, and many of the dodders (Cuscuta) cause damage to crops.
We have rampant bindweed - is it OK to treat the whole old lawn before the new one is put down?
However, some black bindweed is creeping into the picture.
