Origin and History
The poinsettia, scientifically known as Euphorbia pulcherrima, is native to Mexico. The plant was first documented by the Spanish physician and botanist, Dr. Joel Poinsett, in the early 19th century.

Cultural Significance

Its bright red and green colors are reminiscent of the blood and foliage of Mexico, which is why it is often associated with the Day of the Dead and Christmas. The plant’s association with these holidays has made it a popular gift during the festive season.
Appearance and Varieties
Poinsettias come in a variety of colors, including red, pink, white, and even marbled or speckled patterns. The plant’s true flowers are small and white, located at the center of the bracts, which are the colorful, leaf-like structures that give the poinsettia its distinctive appearance.

After the holiday season, cut the stems of the poinsettia to about 6 inches in length.
