How does a poinsettia turn red?

1 Answer

Poinsettias (Euphorbia pulcherrima) need total darkness, for 14 hours each day, starting about eight weeks before you want to display them. During the day, the plants need bright light, along with the other routine care. However, starting in the evening, the plants must get complete darkness.
