What we refer to as National Poinsettia Day is called "La Flor de la Nochebuena" — or Flower of the Holy Night in Mexico. Poinsettias are revered there because of a legend that recounts the story of a poor little girl who despaired of having no gift for Jesus’ birthday.
Poinsettia Day, also known as National Poinsettia Day, is observed on December 12th every year. This holiday celebrates one of the most recognizable plants of the holiday season.
