Colorful Poinsettia
The poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch) is a flowering plant in the Euphorbiaceae family, native to Mexico and Central America. Known for its red and green leaves, it is commonly used in Christmas decorations. The plant became a symbol of Christmas, thanks in part to European missionaries and an American diplomat named Joel Poinsett. Cultivated varieties feature white, pink, mottled, and striped bracts, although solid red varieties are most popular during the Christmas season. Poinsettias change color in response to shorter winter days. The plant has hairless branches, thin leaves, and produces tiny, petal-less flowers. The leaves are typically 12-20 cm long with pointed tips. The flowers are surrounded by male flowers in a cup-shaped series of bracts called a cyathium, with each cyathium featuring two-lipped, yellow glands. The cyathia are green and yellow, surrounded by large, bright red bracts. The plant produces tri-lobed capsules, about 1.5 x 1.5-2.0 cm in size, and the seeds are oval and pale grey. Poinsettias are the bestselling potted plant in the United States and Canada. While not harmful to animal or human health, the plant's sticky white sap can cause skin rashes. Poinsettia plants with colorful red and green leaves were observed in the Tehatta, West Bengal, India, garden on March 29, 2024. (Photo by Soumyabrata Roy/NurPhoto)
