About Hazardia squarrosa (Hook. & Arn.) Greene
Hazardia squarrosa, commonly known as sawtooth goldenbush, is a North American shrub species in the Asteraceae family. It is native to California in the United States and Baja California in Mexico. This species grows in coastal and inland scrub and chaparral habitats. It is a variable-sized shrub, ranging from a low, clumpy form to a sprawling plant reaching over 2 metres (6 ft 7 in) in height. The shrub is covered in thick, sharply toothed leaves that are a few centimeters long, and it is generally not very hairy or woolly. It produces numerous flower heads covered with greenish, pointed phyllaries. Each open flower head holds an array of long yellow to slightly reddish disc florets, and has no ray florets. Three varieties of Hazardia squarrosa are recognized: Hazardia squarrosa var. grindelioides (DC.) W.D.Clark, found from Monterey County to Baja California; Hazardia squarrosa var. obtusa (Greene) Jeps., found in Santa Barbara, Ventura, Los Angeles, and Kern Counties; and Hazardia squarrosa var. squarrosa, found from San Benito County to San Diego County.
