Calystegia macrostegia subsp. tenuifolia
Family: Convolvulaceae · Type: perennial · Native
morning glory is a California native perennial found in central and southern coastal regions, San Gabriel and Santa Monica Mountains, western Peninsular Ranges, and inland dry areas at elevations generally below 500 meters. Flowering in May, this plant produces white flowers with subtle pink or cream tones in large trumpet-shaped blooms 22 to 40 millimeters long. Growing with trailing or weakly climbing stems that are glabrous to slightly hairy, it spreads across the landscape with a flexible, sprawling habit. Its leaves are distinctively linear to narrowly triangular with rounded or squared sinuses, featuring delicate linear lobes that create an intricate foliage pattern. The bracts surrounding its flowers are narrowly lanceolate, 8 to 14 millimeters long with acute tips, adding to the plant's subtle architectural complexity.
