Hollyhock bindweed is a naturalized perennial herb found in southwestern California in disturbed places at elevations below 1,000 meters. Flowering from May to October, this plant produces deep pink to purple funnel-shaped flowers 3 to 4 centimeters long, with a distinctive reflexed peduncle. Growing with climbing stems, it develops distinctively lobed leaves that vary from shallowly notched lower leaves to deeply 3-lobed or multi-lobed upper leaves. Its leaves range from 3 to 4 centimeters long, with an intricate, variable leaf structure that adds visual complexity to the plant. The flower's calyx is 10 to 11 millimeters long, featuring unequal lobes that are widely ovate or spoon-shaped.
