common fleabane

<em>Pulicaria dysenterica</em> is a perennial herbaceous plant belonging to the family Asteraceae within the order Asterales. Commonly known as common fleabane or elecampane, this species typically colonizes damp, disturbed habitats including marshes, riverbanks, roadsides, and wet meadows. It is classified as Least Concern on the IUCN Red List, indicating stable and widespread populations. <em>Pulicaria dysenterica</em> is native to Europe and also occurs in the United States. The plant typically produces branching, woolly-stemmed growth reaching up to 60 centimeters in height, bearing yellow daisy-like flowerheads from mid to late summer that attract a range of pollinating insects. Its leaves are clasping and softly hairy, a characteristic that gives the plant a distinctly woolly appearance. Historically, the species was used in traditional medicine and as an insect repellent, with the common name reflecting both its reputed medicinal properties and the flea-deterring use of its dried foliage. Biological traits of this species remain poorly documented in the scientific literature.
