Devil's Beggarticks ("Bidens frondosa") is an annual herb in the family Asteraceae, native to North America. It looks similar to a "Dahlia" plant, up to 2 m tall, usually with reddish stems. Its flowers are yellow, produced in early autumn, followed by numerous seeds with hooked barbs that attach onto passing animals' fur or clothing or sometimes even skin which allow the seeds to be dispersed widely. The seeds look similar to a tick and give this plant part of its most popular common name.

This plant is invasive in some parts of the world such as Europe, where it is considered "an important threat to plant health, the environment and biodiversity" [http://www.eppo.org/QUARANTINE/ias_plants.htm] . It is known by a variety of different names, including Common Beggarticks, Common Tickseed, Large-leaved Beggarticks, Devil's Bootjack, Devil's Pitchfork, and Pitchfork Weed.
