Calystegia occidentalis subsp. occidentalis

Family: Convolvulaceae · Type: perennial · Native

Western morning-glory is a California native perennial found in the Klamath Ranges, northern Coast Ranges, high Cascade Range, Sierra Nevada, San Francisco Bay Area, and North Coast Ranges in dry slopes, chaparral, and pine woodland at elevations below 1,200 meters. Flowering from May to July, this plant produces white to pale pink flowers with distinctive showy trumpet-like shapes. Growing with stems that can reach over 1 meter long, it develops decumbent to strongly climbing stems that wind through surrounding vegetation. Its leaves have somewhat indistinct lobes with generally two-tipped edges, creating a soft, irregular leaf structure. The plant's delicate bracts near the flower are narrow and linear-oblong, measuring 4 to 18 millimeters long.
