Its Poinsettia Day! Poinsettia (Euphorbia pulcherrima) are part of the spurge family Euphorbiaceae and grow wild along the tropical dry forests from northwestern Mexico to southern Guatemala.
Humans have been cultivating poinsettia since at least the 1500s.
The Aztecs called poinsettia cuetlaxochitl (brilliant flower), the Mayans called it k'alul wits (ember flower), and Flor de Nochebuena (Christmas Eve flower) in Spanish.
In 1828, J. R. Poinsett collected plants near Taxco in northern Guerrero, Mexico and sent specimens to the Bartram Botanical Garden in Philadelphia. They were exhibited to the public the following summer.
Today there are over 300 varieties!
