Grindelia camporum is a species of flowering plant in the daisy family known by the common names Great Valley gumplant and Great Valley gumweed. It is native to California and Baja California, where it can be found in a number of habitats. Its range may extend into Nevada. This hardy plant readily grows in disturbed and altered areas such as ditches and roadsides. It is a gangly weedlike perennial topping two meters in maximum height. Its erect, branching stems are lined with many stiff, wavy-edged, serrated leaves 2 to 3 centimeters long. Atop the stem branches are inflorescences of a single large flower head up to 3 centimeters wide. The head is a vaguely thistlelike cup of green clawlike phyllaries that bend downward. The center of the head is filled with yellow disc florets and there are usually many yellow ray florets around the circumference. The flower head fills with a copious white exudate, especially during the early stages of blooming. This plant has a number of historical medicinal uses.
