Thing Named After Green DayMacrocarpaea dies-viridis - a species of night-blooming flowers within the Macrocarpaea genus named after Billie Joe and co.

From what our research has told us, the flower named after Green Day looks more like a dried-up weed. However, when its in a nocturnal bloom, the particular type of Macrocarpaea named after the punk-rock trio probably looks similar to the picture above (which is actually one of its sister species).

According to Rolling Stone, "Harvard researchers bestowed the name "dies-viridis" (Latin for "green day") upon their newly minted species of night-blooming flower after listening to the band while driving throughout Ecuador on their research trips."

We wonder which Green Day tracks made it onto their road trip playlist... we'd put money on 'Welcome to Paradise.'
