Family: Asteraceae · Type: annual · Native

Cleveland's hayfield tarweed is a California native annual found in southern Klamath Ranges, northern Coast Ranges, western edge of northern Sierra Nevada Foothills, and Sacramento Valley in dry grasslands, chaparral openings, and woodland sites at elevations of 40 to 1,600 meters. Flowering from June to November, this plant produces white ray flowers with distinctive purple veining on heads arranged in spike- or raceme-like clusters. Growing with multiple branches and coarse-hairy stems up to several tens of centimeters tall, it forms open, well-developed side branches. Its leaves are notably coarse-hairy to shaggy, with distal leaves often bearing stalked glands and minutely bristly surfaces. The small fruits are compact, with a width approximately two-thirds of their length.
