Description: Field bindweed (also called creeping jenny or morningglory) is a perennial reproducing by both seeds and underground roots. The root system is very extensive and may penetrate the soil to a depth of 20 to 30 feet. The plant grows prostate or will climb on any nearby object. The spreading stems are smooth, slender, usually twining, and may reach lengths of 2 to 7 feet on a mature plant. The leaves are alternate with smooth margins, and are arrow-shaped with two basal lobes. The flowers are white to pink, approximately 1 inch in diameter, funnel shaped, and are borne singly on long stalks in the axil of the leaf. The flower stalk has 2 bracts located 1/2 to 2 inches below the flower, which helps to distinguish this weed from hedge bindweed. Flowering occurs from May to September. The seeds are borne in seed pods that are egg-shaped and contain four seeds. The seeds are dark brownish-gray, 1/8 inch long, have a roughened surface, and have one rounded and two flattened sides.
