Hypochaeris glabra is an annual herb that is not native to California.
[Cal-IPC] Invasive: Hypochaeris glabra (smooth cat's-ear) is an annual flowering herb (family Asteraceae) found throughout California, except in the Great Basin and desert. Smooth cat?s-ear 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 cat's-ear 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 cat's-ear, but grazing, mowing or burning can encourage growth and seed germination. Although smooth cat's-ear is widespread, its impacts appear to be relatively minor.
