Grindelia camporum (Common gumplant) is a native California subshrub in the Asteraceae family, recognized by widespread range, branching pattern, and involucre characteristics.

Common gumplant is a California native perennial found in the Klamath Ranges, northern Coast Ranges, Sierra Nevada foothills, Central Valley, San Francisco Bay Area, southern Coast Ranges, southwestern California, Sierra Nevada eastern slopes, and Mojave Desert in sandy or saline bottomlands and roadsides at elevations below 1,400 meters. Flowering from May to November, this plant produces yellow flower heads with bright yellow ray flowers 5 to 11 millimeters long in clusters 10 to 22 millimeters wide. Growing with erect, much-branched stems 60 to 250 centimeters tall, it forms a robust and spreading habit. Its leaves are lanceolate to ovate, sessile and clasping, ranging 2 to 15 centimeters long, often resinous and yellow- to gray-green with entire or slightly serrate edges. The fruit is 2 to 5 millimeters long, white to golden-brown with ridged tops and paired pappus awns.
