National Poinsettia Day
December 12

National Poinsettia Day on December 12th celebrates the most iconic, recognizable, and best-selling holiday plant in North America. Decorating porches, living rooms, and religious sanctuaries alike, this vibrant, star-shaped plant is a beloved cornerstone of the Christmas season. However, few people realize that this festive staple carries a rich history spanning hundreds of years, an official Act of Congress, and a unique botanical backstory.

Who Founded National Poinsettia Day?

National Poinsettia Day was officially created by the U.S. House of Representatives in 2002. Congress established the observance to recognize the massive economic impact of the holiday plant industry and to honor the historical significance of the plant's introduction to the United States.

The calendar date of December 12th was intentionally chosen to commemorate the death anniversary of Joel Roberts Poinsett, an American botanist, physician, and the very first U.S. Minister (Ambassador) to Mexico. In the winter of 1825, Poinsett became absolutely captivated by a brilliant red, wild plant growing along the roadsides of Taxco, Mexico. He sent botanical cuttings back home to his personal greenhouses in Charleston, South Carolina. By 1836, the plant had captured the heart of American nurseries and was officially named the "Poinsettia" to recognize the man who discovered it.

(Fun Coincidence: December 12th is also the sacred Mexican holiday of Dia de la Virgen de Guadalupe, where native poinsettias have traditionally been used to decorate streets and altars for centuries!) [1, 2]

The Christmas Legend of the Poinsettia

Long before it arrived in America, the plant was known to native Mexicans as Flor de Nochebuena, meaning "Flower of the Holy Night." Its deep connection to Christmas stems from a touching 16th-century Mexican legend: [1, 2, 3]

According to the story, a young, impoverished girl desperately wanted to present a gift to the baby Jesus at her village church's Christmas Eve nativity display. Having no money, she wept on her way to the chapel, fearing she would have nothing to offer. An angel appeared to her and gently reminded her that any gift given with pure love would be deeply cherished. [1, 2]

The young girl gathered a humble bundle of green weeds from the roadside, walked up to the altar, and placed them at the manger. Miraculously, the moment the weeds touched the display, they burst into brilliant, star-shaped crimson velvet leaves. From that night forward, the star-shaped crimson formations were said to resemble the Star of Bethlehem. [1, 2, 3]

Debunking the Myth: Are Poinsettias Poisonous?

One of the most widespread myths surrounding Christmas is that poinsettias are highly toxic to humans and household pets. This is completely false.

While the plant belongs to the Euphorbia family and produces a milky white sap that can cause mild skin irritation or an upset stomach if chewed on, it is not fatal or severely toxic. A family pet or child would have to consume an entire plant to experience serious illness. While it shouldn't be ingested, you can safely display them on your kitchen counters and coffee tables without worry. [1]

(Botanical Secret: The striking red "petals" of the poinsettia are not actually flowers at all! They are specialized leaves called bracts. The true flowers are the tiny, yellow button-like clusters sitting right in the center of the leaves, known as cyathia).

Expert Tips: How to Care For and Grow Poinsettias

Poinsettias are tropical plants native to warm Mexican climates, which means they require specific conditions to survive the cold winter months indoors. Use these expert guidelines from the University of Minnesota Extension to keep your holiday display thriving long past Christmas Day: [1, 2, 3]

1. Lighting and Warmth

• Provide bright, indirect sunlight: Place your plant in a room that receives plenty of bright natural light, but keep it out of harsh, direct afternoon sun rays.

• Maintain steady temperatures: Poinsettias thrive in environments between 65 and 70 degrees Fahrenheit

• Avoid drafts: Keep your plants far away from cold windows, chilly exterior doorways, fireplaces, space heaters, and drying heating vents. Exposure to temperatures below 50 degrees Fahrenheit will cause their leaves to droop and drop rapidly. [1, 2, 3]

Strategic Watering (The Golden Rules)

• Check the soil daily: Water your plant only when the surface of the soil feels dry to a light touch, or when the pot feels noticeably lightweight when lifted.

• Never let them sit in standing water: Most festive poinsettias come wrapped in decorative foil. Take the plant completely out of the foil cover, place it in the sink, and water it thoroughly until moisture drains freely out of the bottom holes. Let it drain fully before placing it back into its decorative sleeve. Soggy, trapped water will rapidly rot the roots and kill the plant.

3. How to Make Your Poinsettia Rebloom Next Year

Most people throw their plants away in January, but you can easily grow them year-round as lush green houseplants and force them to turn bright red again for next Christmas! [1, 2]

• Spring Pruning (March/April): When the red bracts begin to fade and drop, prune each branch back to about 4 to 6 inches in height to promote a compact, bushy shape. Begin feeding it once a month with half-strength houseplant fertilizer. [1, 2, 3]

• Summer Outdoor Move: Once nighttime temperatures stay reliably above 50 degrees Fahrenheit, you can move your pot outdoors into a part-sun garden area. Pinch back the tips of the stems a few times during the summer to encourage side branching. [1, 2, 3]

• The Autumn Blackout Routine (September/October): Poinsettias are "short-day" plants, meaning they require long periods of uninterrupted darkness to stop producing green chlorophyll and start turning red. Starting around October 1st, give your plant 14 hours of absolute darkness every single night. Cover it with a heavy cardboard box or place it in a pitch-black closet from 5:00 PM to 8:00 AM daily. [1, 2, 3]

• Christmas Bloom: After 8 to 10 weeks of this strict light control, your beautiful red holiday bracts will be fully formed and ready to take center stage for National Poinsettia Day! [1, 2]
