Poinsettia Meaning: The Mexican Legend, Joel Poinsett and the Real Story of the Christmas Flower
What the poinsettia means, the Mexican legend of the Christmas Eve flower, how Joel Poinsett gave it its name and what its colors are said to stand for.
Every December, tens of millions of poinsettias move through American supermarkets, churches and living rooms. This guide explains where the plant comes from, the Mexican legend behind its Christmas role, how it got its English name and what its colors are said to mean. It separates the documented history from the stories, and it does not claim the plant has powers.

The poinsettia is a Mexican shrub, Euphorbia pulcherrima, whose red leaves have become the best-known Christmas plant in the United States. In Mexico it is called flor de Nochebuena, the Christmas Eve flower, after a legend about a poor girl whose roadside weeds turned red at the Nativity scene. The Aztecs knew it as cuetlaxochitl and used it for dye; the US diplomat Joel Roberts Poinsett brought it north in 1828, and December 12, the day he died, is National Poinsettia Day. Its symbolism of humble gifts and Christmas light is tradition; the plant does not bring luck, and it is far less toxic than its reputation.
Joel Roberts Poinsett sent poinsettia cuttings to South Carolina in 1828 and died on December 12, 1851, the date now observed as National Poinsettia Day.

Quick answer
The poinsettia is a Mexican shrub, Euphorbia pulcherrima, whose red leaves have become the best-known Christmas plant in the United States. In Mexico it is called flor de Nochebuena, the Christmas Eve flower, after a legend about a poor girl whose roadside weeds turned red at the Nativity scene. The Aztecs knew it as cuetlaxochitl and used it for dye; the US diplomat Joel Roberts Poinsett brought it north in 1828, and December 12, the day he died, is National Poinsettia Day. Its symbolism of humble gifts and Christmas light is tradition; the plant does not bring luck, and it is far less toxic than its reputation.
What the poinsettia means
In Christian tradition the poinsettia carries three meanings, all of them later than the plant itself. The red stands for the blood of Christ and for love, the green for life that continues in winter. The star shape of the leaves is read as the Star of Bethlehem. And the legend attached to it, told below, makes it a flower of humble gifts: what you can give matters more than what it costs.
In Mexico the plant is simply flor de Nochebuena, the Christmas Eve flower. It decorates churches and Nativity scenes from early December and is carried by children in the processions of Las Posadas, the nine nights before Christmas.
Outside religious use, the poinsettia has become a general symbol of the season, of hospitality and of good cheer. That broad meaning is cultural and commercial at once: in the United States it is the best-selling potted plant of the year, and almost all of those sales happen in a six-week window.
Cuetlaxochitl: the plant before Christmas
Long before it was a Christmas plant, the poinsettia was a wild shrub of the Pacific slope of Mexico and Central America, growing into a lanky bush with tall stems and red leaves that show in the dry winter months.
The Aztecs called it cuetlaxochitl (roughly kwet-la-sho-chitl). They grew it as an ornamental, used its red leaves to make red and purple dyes and used its milky sap in medicine. The Maya knew it as k'alul wits, often translated as "ember flower".
After the Spanish conquest, Franciscan friars around Taxco in the sixteenth century are reported to have used the plant to decorate Nativity scenes, because it turns red at exactly the right time of year. That timing is not a miracle but botany: the poinsettia is a short-day plant, and its leaves color as the nights grow long.
The legend of Pepita and the flower of the holy night
The legend that gave the plant its Christmas meaning exists in many versions. The best known goes like this.
A poor girl, usually called Pepita, walks to church on Christmas Eve. Everyone else brings a gift to the Christ Child in the manger, and she has nothing. A cousin, an angel or a voice tells her that any gift given with love is enough. On the way she gathers a handful of weeds from the roadside. When she lays them at the manger, they burst into brilliant red stars. Those who see it call them flores de la Nochebuena, flowers of the holy night.
Some tellings name the child Pepita, others give a boy named Pedro, and some put the scene in Taxco. The story cannot be dated to a source or an author; it has the shape of a teaching legend, told to children, that explains a familiar sight in church.
Why the legend lasts
The Pepita story is a story about worthiness: the poorest gift is welcomed. That is why many families retell it while setting the plant out. It also explains, in a child's terms, why a common roadside weed became the flower of Christmas Eve.
Joel Roberts Poinsett and how the plant got its English name
The English name comes from Joel Roberts Poinsett of South Carolina, an amateur botanist and the first United States minister (ambassador) to Mexico. In 1828 he sent cuttings home to his greenhouses in Charleston, the first recorded arrival of the plant in the United States.
Poinsett went on to serve as Secretary of War. He died on December 12, 1851, and that date is now National Poinsettia Day, made official by Congress in 2002. December 12 is also the feast of Our Lady of Guadalupe in Mexico, a coincidence many Mexican-American families note.
The plant's American career took off in the twentieth century. Paul Ecke Sr. founded a ranch in Encinitas, California, in 1923 and the family developed compact, long-lasting varieties that could be grown indoors and shipped. For decades the Ecke Ranch supplied a large share of the poinsettias sold in the United States, and the family promoted the plant through television holiday specials.
Some Mexican writers point out that the name honors a diplomat whose career in Mexico was controversial. Many prefer cuetlaxochitl or Nochebuena.
Bracts, not petals: what you are actually looking at
The red "petals" of a poinsettia are not petals. They are bracts, modified leaves that change color. The real flowers are the small yellow-green buds in the center, called cyathia.
The plant colors when nights are long. In nature that happens from late autumn; in greenhouses, growers control it with blackout curtains. If you want a plant to color again next year at home, it needs about fourteen hours of uninterrupted darkness each night for eight to ten weeks, usually starting around October 1, and bright light during the day.
A healthy plant in the store has tight, unopened yellow buds in the center. When the buds have dropped, the plant is older and will lose its bracts sooner.
Is the poinsettia poisonous?
The plant's poisonous reputation is mostly a myth. It is usually traced to a 1919 case of a two-year-old whose death was blamed on a poinsettia leaf without proof. Later data, including the POISINDEX poison information database cited by Ohio State University, found that a 50-pound child would have to eat hundreds of leaves (often quoted as more than 500) to reach a harmful dose.
That does not mean it is food. The milky sap can irritate skin and eyes, and people with a latex allergy may react to it, since the plant is related to rubber-producing species. The ASPCA lists the poinsettia as mildly toxic to cats and dogs, usually causing drooling or an upset stomach. Keep it out of reach of pets that chew plants and wash your hands after pruning.
Poinsettia colors and what people read into them
Poinsettia colors and their modern associations
| Color | Common association | Where it comes from |
|---|---|---|
| Red | Love, sacrifice, the Christmas Eve legend | Traditional Christian reading |
| White | Purity, peace, remembrance | Modern church and wedding use |
| Pink | Gentleness, gratitude | Florist meaning, twentieth century |
| Marbled or speckled | Joy, playfulness | Florist meaning, recent cultivars |
| Dyed blue or glittered | Decorative only | Painted bracts, no tradition |
Only the red carries the old legend. The other meanings come from the language of flowers used by florists and are best read as modern conventions, not folklore.
Temple Tip
Set the plant out on the evening of December 12, National Poinsettia Day, rather than the day you buy it. Tell the Pepita story once, out loud, to whoever is at home. Giving the plant a start date turns a supermarket purchase into a small seasonal ritual.

Voices from practice
People who grew up in Mexican-American homes often describe the poinsettia less as decoration than as part of church: the plant arrives with the Nativity scene and leaves with it.
Gardeners who try to make a plant rebloom commonly report that the darkness schedule is the hard part. One evening of a lamp turned on in the room can delay the color by days.
Many people say the legend changed how they see the plant. Once you know it began as a gift of weeds, the cheap supermarket pot feels less like a cliché and more like the point.
What we don't promise
We do not claim the poinsettia brings luck, protection or prosperity. Those meanings circulate online, but they have no basis in the plant's history or in the legend.
We do not treat the Pepita story as history. It is a teaching legend with many versions and no known author.
And we do not give medical advice. The plant is far less toxic than its reputation, but if a child or pet has eaten a large amount or shows symptoms, call Poison Control or your veterinarian.
Practically: how to work with this
- Choose well. Look for tight yellow buds in the center, no drooping leaves and a plant that was not displayed in a cold doorway.
- Carry it home warm. Poinsettias are tropical. Wrap the plant for the trip; a few minutes below 50°F can damage it.
- Give it light and steady warmth. Bright indirect light, room temperature, away from drafts and heaters. Water when the soil surface is dry and empty the saucer.
- Give it a date. Set it out on December 12 or on the first night of Las Posadas, December 16, and keep it until Epiphany on January 6.
- Add a story and a light. Tell the legend once and light a candle beside the plant on Christmas Eve. Pair it with a Yule simmer pot if you want the house to smell of the season.
- Decide on January. Compost it, or try to keep it: cut it back in spring, put it outside in summer and start the darkness schedule around October 1.

Frequently asked questions
What does the poinsettia symbolize?
In Christian tradition the red stands for love and the blood of Christ, the star-shaped leaves for the Star of Bethlehem and the Mexican legend for the value of a humble gift. More broadly it symbolizes the Christmas season and hospitality.
What is the Mexican legend of the poinsettia?
A poor girl, often called Pepita, has no gift for the Christ Child on Christmas Eve. She brings roadside weeds, which turn into red flowers at the manger. That is why the plant is called flor de Nochebuena, the Christmas Eve flower.
Why is it called a poinsettia?
It is named after Joel Roberts Poinsett, the first US minister to Mexico, who sent cuttings to South Carolina in 1828. In Mexico it is called flor de Nochebuena, and the Aztec name is cuetlaxochitl.
When is National Poinsettia Day?
December 12, the anniversary of Joel Poinsett's death in 1851. Congress made the day official in 2002.
Are poinsettias poisonous to people and pets?
Much less than their reputation suggests. The sap can irritate skin, and the ASPCA lists the plant as mildly toxic to cats and dogs, usually causing drooling or an upset stomach. Keep it out of reach and call Poison Control or a vet if a lot was eaten.
How do I make a poinsettia turn red again?
Give it about fourteen hours of complete darkness each night for eight to ten weeks, usually from around October 1, with bright light during the day. Color begins after six to eight weeks.
