Calystegia collina

Coast range false bindweed

Family: Convolvulaceae · Type: perennial · Native

Coast range false bindweed is a California native perennial herb found in Coast Range bioregions in rocky or gravelly areas. Flowering from May to July, this plant produces white flowers 25 to 55 millimeters long with delicate, slightly flared trumpet-like form. Growing with decumbent stems that spread low to the ground, it forms a low-growing mat with soft, tomentose (woolly) texture. Its leaves are generally less than 3 centimeters wide, distinctively reniform or kidney-shaped with wavy margins and indistinct basal lobes. The plant emerges from underground rhizomes, creating subtle patches in its rocky habitat.
