An enchanting legend of the Poinsettia dates back to several centuries ago in Mexico. Pepita had no gift for the Christ child. On her way to church, Pepita gathered some weeds. As she approached the altar, the weeds blossomed into brilliant flowers. Then they were called Flores de Noche Buena-Flowers of the Holy Night. Now we call them Poinsettias. Joel Robert Poinsett, an amateur botanist, is credited with bringing poinsettias to the U.S. in 1825. December 12 is National Poinsettia Day.
