Detailed explanation-1: -The poinsettia (/pɔɪnˈsɛt(i)ə/; Euphorbia pulcherrima) 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.

Detailed explanation-2: -Plant them in a sunny, well-drained location protected from north winds and frost. The south side of a house or wall is usually a good spot. Make sure the location receives no artificial light at night from flood lights, street lights or porch lights, as this can prevent poinsettias from blooming properly.
