The 'Bidens hyperborea' meme, commonly known as 'Chudweed,' is a surreal intersection of botany and niche internet subcultures. It stems from the discovery that Bidens hyperborea is the legitimate scientific name for the Estuary Beggarticks plant. Internet users quickly connected the genus name to Joe Biden and the species name to 'Hyperborea,' a mythical northern land frequently referenced in esoteric 'schizoposting' and 'Chud-core' aesthetics. The meme typically features Joe Biden edited with glowing blue eyes, ancient runes, or grainy VHS filters to suggest a hidden, mystical lineage. It is used to mock political seriousness by blending botanical facts with absurd, high-energy conspiracy aesthetics.
