From Wikipedia, the free encyclopedia
Psilostrophe cooperi is a flowering plant in the daisy family known by the common names Cooper's paper daisy and whitestem paperflower. It is native to the Mojave and Sonoran Deserts of the United States and Mexico. This is a low, spreading bush with pale green, hairy foliage. The daisylike flower heads have 3 to 8 deeply toothed golden-yellow ray florets. The flower heads are often bunched together at the tops of the stems in a rounded spray. The flowers persist for a time and then dry and become papery while maintaining their yellow color.
