Cotton morningglory

Purple bindweed can be found growing in sandy soils in the South Texas Plains and the Edwards Plateau. It is often considered a pest when growing in flower beds and gardens. The leaves are heart-shaped or three-lobed and are approximately 1 1/2 to 2 1/2 inches long. The pink flower has a dark maroon to purple throat and is about 2 inches wide in diameter. Purple Bindweed blooms from April to October. The leaves are eaten by white-tailed deer and the seeds are consumed by quail.
