Hemizonia congesta ssp. cleveland (Cleveland's hayfield tarweed)

Plant Description: An annual herb that is native to California, southwestern Oregon and also found elsewhere in western North America.

This is a spindly, thin-stemmed annual herb growing erect to 10 to 80 centimeters in height. Like other tarweeds the stem and foliage are hairy and have an odor reminiscent of tar. Most of the long, narrow, pointed leaves are located on the lower portion of the stem below the branching. The flower clusters are covered in hairy hairs and hold daisylike flower heads. Each head has a center of yellowish dark-tipped disc florets and a fringe of bright yellow to white ray florets, often with purplish striping on the undersides. The ray florets are toothed or lobed on the tips, with the middle tooth thinner than the others.
