Bindweed is an invasive plant that wraps its stems around other plants in the garden to grow. Field bindweed can be recognized by its small pink flowers, which only open in the presence of sunlight.
Hedge bindweed has white flowers that are a little larger than those of Convolvulus arvensis. Care and perseverance are required to eliminate this stubborn plant, says Tom Meaker, author of the book "Bindweed: A Gardener's Guide to Getting Rid of This Invasive Plant"
