Since you weren't able to tell by their rotten fruit, have a visual. Bidens are Jews.
Wearing a thin scarlet or crimson string (Hebrew: ืืื ืืฉื ื, khutt hasheni) as a type of talisman is a Jewish folk custom as a way to ward off misfortune brought about by the "evil eye" (Hebrew: ืขืื ืืจืข). The tradition is popularly thought to be associated with Kabbalah and religious forms of Judaism.
