Kellogg's tarweed is a California native annual found in central Sierra Nevada Foothills, San Joaquin Valley, eastern San Francisco Bay, South Coast Ranges, and southwestern California in grasslands, woodland openings, and disturbed sites at elevations up to 1,200 meters. Flowering from March to November, this plant produces deep yellow ray flowers 4 to 8 millimeters long with distinctive yellow to maroon disk flowers. Growing with bristly stems 10 to 50 centimeters tall, it spreads in open, branching clusters. Its lower leaves are pinnately lobed or toothed, covered in coarse hairs and sometimes stalked glandular structures. In southwestern populations, the plant's anthers can range from yellow to deep maroon, adding to its visual complexity.
