National Poinsettia Day

National Poinsettia Day, observed on December 12, celebrates one of the most recognizable flowers of the holiday season. With its vivid red bracts and deep green leaves, the poinsettia brings warmth and festive color to homes, workplaces, churches, and community spaces during winter.

The observance also honors the plant’s cultural history and its connection to Joel Roberts Poinsett, the first U.S. minister to Mexico, who introduced the poinsettia to the United States in the 1820s. On December 12, people can mark the occasion by displaying a poinsettia, learning about its origins, or sharing one as a thoughtful seasonal gift.

National Poinsettia Day is observed annually on **December 12**. The date commemorates the death of Joel Roberts Poinsett, the American diplomat, physician, and botanist who introduced the poinsettia to the United States. Poinsett encountered the plant—known in Mexico as *cuetlaxochitl*—while serving as the first U.S. minister to Mexico in the 1820s. He sent cuttings to his home in South Carolina, where he cultivated and shared them with botanical gardens and horticultural contacts.

The plant was later named *Euphorbia pulcherrima*, meaning “the most beautiful euphorbia.” Its familiar red “flowers” are actually modified leaves called bracts, while the small yellow structures at their center are the true flowers. In Mexico, the plant already had cultural importance before its arrival in the United States. Indigenous peoples used it for dye and medicinal purposes, and a Mexican Christmas tradition connected its red foliage with the story of a poor child who brought weeds to an altar, where they miraculously bloomed into poinsettias.

Over time, the poinsettia became closely associated with Christmas in the United States and other countries. Its winter coloring, traditional red-and-green palette, and ability to thrive indoors helped make it a popular seasonal decoration. The Ecke family and their California nursery played a particularly important role in developing modern poinsettia production and marketing, helping transform the plant from a specialty greenhouse specimen into a widespread holiday crop. Breeders have since introduced white, pink, speckled, and other varieties, although red remains the best-known.

National Poinsettia Day developed as a way to recognize both the plant’s botanical history and its place in holiday culture. Observed on **December 12**, it recalls Poinsett’s contribution while celebrating the horticultural industry, Mexican heritage surrounding the plant, and the poinsettia’s enduring symbolism of Christmas and seasonal goodwill. Modern observances commonly include displaying poinsettias, learning about their care and history, and giving the plants as gifts.
