Plagiobothrys canescens is an annual herb with a spreading or erect stem 10 to 60 centimeters in length. The leaves are located in a basal rosette about the base of the stem, with smaller ones located along the stem's length. The plant is coated in long, rough hairs and sometimes bristles. It is purple-edged and -veined and leaks purple juice when crushed. The inflorescence is a series of tiny flowers and hairy bracts. Each five-lobed white corolla measures 2 to 3 millimeters wide. The fruit is a rounded, arched nutlet no more than 2 millimeters long texured with cross-ribs.
