Christmas-flower
The Christmas flower (Euphorbia pulcherrima), universally known as the poinsettia, is a shrub or small tree in the family Euphorbiaceae, native to Mexico and Central America. In its native habitat it can reach heights of several meters, growing in seasonally dry tropical forests and woodland margins. The species is globally recognized as the quintessential Christmas ornamental plant, grown commercially on a massive scale for the holiday season in the Northern Hemisphere. What appear to be colorful flowers are in fact specialized leaf bracts — modified leaves in red, pink, white, or multicolored forms — that surround the small, true flowers called cyathia. Flowering is triggered by short days and long nights, a photoperiodic response that in nature aligns with the shortening days of autumn and winter. The milky white latex sap of poinsettias is mildly irritating to skin and mucous membranes, though contrary to popular belief the plant is not highly toxic to humans or most animals. In Mexico, the poinsettia has been cultivated for centuries and holds cultural and medicinal significance in traditional practices. Wild populations in Mexico face some pressure from habitat loss, though the species is not considered globally threatened.
