The red patches on a poinsettia's bracts are actually modified leaves, not flowers. These vibrant colors are a result of pigments called anthocyanins, which help attract pollinators and signal the plant's readiness for reproduction. The color change is also influenced by environmental factors, particularly light exposure and temperature, as the plant responds to the shorter days of winter. This adaptation enhances its visual appeal during the holiday season, making it a popular ornamental plant.

How do you turn poinsettia plants red?
To encourage poinsettia plants to turn red, you need to provide them with specific light conditions. Starting in late September, place the plants in complete darkness for at least 14 hours a day, ensuring they receive bright, indirect light during the remaining hours. This darkness triggers the plant's natural response to produce the red bracts. Continue this routine for about 6-8 weeks until the desired color develops.
