Cuesta Pass Sidalcea has multiple, ascending stems from 0.4 to 1 m long. Each stem bears many flowers, which are less than 1 inch in diameter and have bright pinkish lavender petals. This species is a typical "fire follower", with 1000's of plants reported within the first 2-3 years following a chaparral fire. However, most populations appear to have relatively few plants after 5 or more years following such fires. Regardless, the documented distribution is restricted to about 4-5 occurrences in an area of no more than 5 square kilometers.
