Plagiobothrys hirtus is an annual herb in the borage family (Boraginaceae). Individual plants are between 7 (2.75 inches) to 60 cm (23.6 inches) tall, with narrow hairy leaves along hairy stems. Flowers are five-petaled, trumpet-shaped, mostly white with yellow centers, and positioned in a hairy calyx. Flowers occur on paired coiled inflorescences. Each flower produces four tan to black-colored nutlets which will germinate readily (Amsberry and Meinke 2009).
