Red tends to be the color of the bracts of poinsettias (Euphorbia pulcherrima) in Mexico.

Specifically, bracts are modified leaves. They may be either true or transitional. True bracts are red and surround the plant's dainty, inconspicuous yellow flower. Transitional bracts are located between the true bracts and the plant's regular, green leaves. They start out green but turn red by the end of the year, in sync with the appearance of the poinsettia flower.

Poinsettias are native to southwestern Mexico and southwards through Central America. For centuries there it has tended to be allowed to grow as a late-blooming, perennial shrub in the wild and as a cultivated annual plant for cultural events and religious rituals. But with the scientific and technological changes of the 20th and 21st centuries, it is possible to cultivate poinsettia colors in many different colors, shapes and sizes.
