Euphorbia pulcherrima Willd. ex Klotzsch

Euphorbia pulcherrima Willd. ex Klotzsch. The poinsettia is a commercially important flowering plant species of the diverse spurge family Euphorbiaceae. Indigenous to Mexico and Central America, the poinsettia was first described by Europeans in 1834. It is particularly well known for its red and green foliage and is widely used in Christmas floral displays. It derives its common English name from Joel Roberts Poinsett, the first United States minister to Mexico, who is credited with introducing the plant to the US in the 1820s; however, there have been recent efforts to rename the flower to its Nahuatl name, "cuetlaxōchitl", due to Poinsett's involvement in slavery and the Trail of Tears. Poinsettias are shrubs or small trees, with heights of 0.6 to 4 m. Though often stated to be highly toxic, the poinsettia is not dangerous to pets or children. Exposure to the plant, even consumption, most often results in no effect, though it can cause nausea, vomiting, or diarrhea.
