High Quality Content by WIKIPEDIA articles! Euphorbia pulcherrima, commonly known as poinsettia, is a species of flowering plant indigenous to Mexico and Central America. The name "poinsettia" is after Joel Roberts Poinsett, the first United States Minister to Mexico, who introduced the plant into the US in 1828. It is also called the Ataturk flower. Euphorbia pulcherrima is a shrub or small tree, typically reaching a height of 0.6 to 4 m (2 to 16 ft). The plant bears dark green dentate leaves that measure 7 to 16 cm (3 to 6 inches) in length. The colored bracts—which are most often flaming red but can be orange, pale green, cream, pink, white or marbled—are actually leaves. The colors come from photoperiodism, meaning that they require darkness for 12 hours at a time to change color. At the same time, the plants need a lot of light during the day for the brightest color.
