Common names: Spanish false fleabane, Spanish sunflower

Pulicaria paludosa Link (Spanish false fleabane; Asteraceae) is an annual, biennial, or short-lived perennial that thrives in moist areas. It has simple, clasping leaves, a branched growth habit, and can grow up to a meter tall with a woody rhizomatous root system. It is native to the Mediterranean region of Portugal and Spain and was first reported in Orange County, California, in 1946. Pulicaria paludosa has since spread across Southern California and now occurs in in Clark County Nevada and Western Arizona, favoring disturbed sites along roadsides, wetlands, riparian corridors, and other damp, disturbed sites. It can form monocultures where it has become established and is considered a threat to native riparian species. Seed morphology suggests that it disperses mostly by wind, water, and soil movement. It is difficult to control due to its ability to resprout from rhizomes.
