What is Poinsettia
Poinsettia (Scientific name: Euphorbia pulcherrima) is native to Mexico and is an evergreen shrub of the Euphorbiaceae family. It is Christmas flower to greet the best time in the popular Christmas season. What looks like a red flower is a bract, not a flower. The name poinsettia is derived from Mexican ambassador J. R. Poinset of the United States brought back from Mexico and was disseminated. Because it is a short day plant, beautiful bracts will be for appreciation by suppressing sunshine hours from around September by enclosing it in a cardboard box every evening to the next morning.
