The common name for the plant Euphorbia pulcherrima is the poinsettia. Native to Central America, this flowering plant is especially popular during the Christmas season, characterized by its vibrant red and green foliage. The poinsettia's name honors Joel Poinsett, the first U.S. ambassador to Mexico, who introduced the plant to the United States in the 1820s. Poinsettias are often used in holiday decorations and are marketed during this festive period. While they are often thought to be poisonous to pets, studies indicate that they are relatively non-toxic, making them a favored choice for seasonal decor.
