An excerpt from the article 16 facts about Poinsettia
It grows best in a bright spot, but not in direct sunlight. Too much direct light may cause its colorful bracts to start lose their color. It likes warm places around 21°C (70 °F) and doesn't tolerate draughts so needs watering when the substrate in the pot gets slightly dry.
