Ragweeds (Ambrosia), also called bitterweeds or bloodweeds, are a genus of flowering plants from the sunflower family (Asteraceae). The scientific name of this genus is sometimes claimed to be derived from the Ancient Greek term for the perfumed nourishment of the gods, ambrosia (ἀμβροσία), which would be ironic, since the genus is best known for one fact: its pollen produces severe and widespread allergies. However, the generic name is actually cognate with the name of the divine dish, both being derived from ambrotos (άμβροτος), "immortal". In the case of the plants, this aptly refers to their tenacity, which makes it hard to rid an area of them if they occur as invasive weeds.
