Poinsettias (Euphorbia pulcherrima) is a shrub or small tree. The plant bears dark green dentate leaves that measure 7 to 16 cm 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. The flowers are grouped within the small yellow structures found in the center of each leaf bunch, and they are called cyathia.
