Common names: smooth cat's-ear
Hypochaeris glabra (smooth catsear) is an annual flowering herb (family Asteraceae) found throughout California, except in the Great Basin and desert. Smooth catsear prefers disturbed places, such as roadsides, orchards and landscaped areas, as well as grasslands, woodland and scrub. It is commonly found in overgrazed rangeland. The yellow flowers of smooth catsear look similar to dandelion flowers, and produce seeds that are dispersed by the wind, soil movement, and by clinging to animals and humans. Cultivation can be used to control smooth catsear, but grazing, mowing or burning can encourage growth and seed germination. Although smooth catsear is widespread, its impacts appear to be relatively minor.Rating: Limited
