In a Spring in which there has been little rain and a reduced number of wildflowers, the vibrant yellow of gumplant has been a welcome sight along Ahmanson's main trail in Upper Las Virgenes Canyon Open Space Preserve near the Victory trailhead.

This appears to be Grindelia hirsutula var. hirsutula, a species considered rare in Ventura County. It is reported that a species of gumplant was used medicinally by the Chumash, and other native peoples within its range, for treatment of pulmonary problems.
