Family: Convolvulaceae · Type: perennial · Native

Coastal morning-glory is a California native perennial vine found in the northern Channel Islands in coastal scrub habitats at elevations generally below 500 meters. Flowering from April to July, this plant produces white to pale pink flowers with trumpet-shaped corollas 36 to 60 millimeters long. Growing as a climbing vine often exceeding 4 meters in length, it develops nearly smooth stems with age. Its leaves have distinctive two-tipped lobes and widely rounded sinuses, creating a unique leaf structure. The plant is characterized by large, widely ovate bracts 13 to 26 millimeters wide that are strongly keeled and sometimes sac-like in appearance.
