A trailing or climbing summer annual with light blue flowers that may reach 6-1/2 feet in length. Smallflower morningglory is an isolated weed of agronomic crops, nurseries and landscapes. Cotyledons are rounded with slight indentations and resemble those of a mustard seedling. Mature plants have leaves that occur on petioles arranged alternately along the stem. Leaves are ovate in outline, approximately 1-1/4 to 4-1/2 inches long by 3/4 to 3 inches wide. Hairs occur on the leaf margins and only occasionally on the leaf surfaces.
