Calystegia macrostegia subsp. arida

Family: Convolvulaceae · Type: perennial · Native

Coastal morning glory is a California native perennial found in southern California, including the Santa Barbara Mountains, San Bernardino Mountains, and northern Peninsular Ranges in coastal scrub and chaparral at elevations below 1,000 meters. Flowering from May to June, this plant produces white flowers with pale pink or cream shading, emerging from lanceolate bracts 10 to 21 millimeters wide. Growing with slender, trailing or weakly climbing stems that are distinctly hairy, it spreads across the landscape with a flexible growth habit. Its leaves have rounded to square-shaped sinuses with single-tipped lobes, creating a delicate and intricate foliage pattern. The sepals measure 9 to 12 millimeters long, supporting a corolla that ranges from 24 to 34 millimeters in length.
