Family: Convolvulaceae · Type: perennial · Native

Morning glory is a California native perennial found in southern coastal regions including the Southern California Coast, southern Channel Islands, southern Western Transverse Ranges, San Gabriel Mountains, and northern Peninsula Ranges at elevations generally below 200 meters. Flowering from March to August, this plant produces white to pale pink flowers large and bell-shaped, approximately 32 to 40 millimeters long. Growing with trailing or climbing stems that are glabrous to slightly hairy, it spreads across coastal and inland hills with flexible, sprawling habit. Its leaves have rounded to slightly angular lobes with acute to rounded sinuses, creating a distinctive heart-shaped outline. The plant's large bracts are lanceolate, 10 to 20 millimeters long and 6 to 12 millimeters wide, providing additional structural interest.
