With the arrival of the holidays, the poinsettia flowersPoinsettias, or other flowers, once again become the absolute stars of the show. Christmas decorationIts red, pink or white bracts fill living rooms, shops and squares with color, to the point that it is difficult to imagine a December without this plant in any corner of Spain.
Beyond its image as an ephemeral decoration, the poinsettia is a a species with a history, symbolism, and very specific care requirementsChoosing the right specimen, knowing where to place it, understanding how it is produced in nurseries, and knowing its role in squares and streets helps to enjoy it for much longer, without it becoming a "use and throw away" plant when the Three Kings are over.
A plant with a history and many names
The poinsettia, whose scientific name is Euphorbia pulcherrimait's originally from Mexicowhere it has traditionally been associated with purity and winter celebrations. There it goes by other names, such as Santa Claus, while in Argentina it is known as Federal Star, reflecting its strong symbolic weight in different countries.
In its place of origin it was known as CuetlaxochitlThe word "poinsettia" comes from the Nahuatl word "poinsettia," which translates to "flower that withers." Over time, the plant spread to the rest of the world thanks to Joel Roberts Poinsett, an American diplomat who introduced it to the United States in the 19th century, and whose surname gave rise to the term "poinsettia."
Today, the anniversary of his death, December 12It is commemorated as International Poinsettia Day. Every year, this event serves as an opportunity to promote educational activities and campaigns, reinforcing its status as universal floral symbol of Christmas.
Although its red “flowers” are what attract the most attention, they are actually colored bracts surrounding very small, true flowers of a greenish-yellow hue. These bracts can be red, white, pink, yellow, or bicolored, and their color is intensified by pigments called anthocyaninswhich manifest themselves when the plant goes through prolonged periods of darkness.
Production and prominence in Spain and Europe
In Europe, and especially in Spain, the poinsettia is one of the best-selling ornamental plants in winterIt is estimated that production in Spain alone is around 10 billion units per yearwhich gives an idea of the economic and cultural weight it has during the weeks leading up to Christmas.
Much of this production is concentrated in specialized greenhouses, where every detail of the growing cycle is controlled. In the Marina Alta region, for example, a nursery located between Pego and l'Atzúbia has specialized in grow poinsettias from scratch as a way to complete the period of lower horticultural activity between August and December.
In these production centers, the work with the poinsettia begins in midsummerThe plants are established in August, taking advantage of the heat, so that they can complete their development with the arrival of the cold in DecemberDuring those months, temperatures, ventilation, and humidity are closely monitored, as the poinsettia is very sensitive to sudden changes and to excess water.
To keep the plants healthy, the producers apply pest control treatments such as whiteflies and fungal diseases like botrytisIn addition, recourse is made to growth regulators to control the size of the plants and achieve compact and homogeneous specimens, as demanded by the Christmas decoration market.
The critical moment for cultivation arrives when the time change in October and the hours of daylight decrease. It is then that the plant detects the shortening of the days and the process is triggered. coloration of the bractsIn this phase, treatments that may stain the leaves are suspended and the following are used: thermal screens to protect them from night dew, reducing the risk of rot without soaking the plant.
Urban campaigns and festivals: from greenhouses to squares
Nursery production also has a clear outlet in the public sector. Every December, numerous Spanish cities are filled with color thanks to mass planting campaigns of poinsettias in roundabouts, gardens, squares and flowerpots, with the aim of reinforcing the festive atmosphere in the streets.
In Las Palmas de Gran Canaria, for example, the City Council has installed more than 25.000 copies distributed throughout the city's five districts. Parks, roundabouts, and pedestrian areas are adorned in red to offer a uniform and welcoming Christmas image both residents and visitors.
However, these types of campaigns are not without their problems. In the capital of Gran Canaria, issues have been reported in different seasons. mass thefts of poinsettiaswith hundreds of plants stolen in just a few weeks. In some squares, the number has reached dozens of sudden disappearances, forcing the continuous replacement of specimens and generating considerable economic losses for the municipal coffers.
Officials from the Parks and Gardens department, along with the mayor's office, have described these events as uncivil actsRemembering that these are decorative elements intended for collective enjoyment. The cost of each plant, which can range from about 3 and 10 euros Depending on the size and point of sale, the cost multiplies if the planting and replenishment work is added, resulting in an expense that can easily reach several thousand euros.
In other towns, the approach is more educational. In La Orotava (Tenerife), for example, the City Council promotes campaigns in which Schoolchildren participate in the planting Thousands of poinsettias have been planted in squares and entrances to the municipality. This aims to strengthen the emotional connection of young children with green spaces and convey to them the importance of Do not uproot or damage the plantsmaking them ambassadors of respect for the urban environment.
European events and dissemination of the crop
The role of the poinsettia is not limited to production and retail sales. Initiatives such as Stars for Europe (SfE)A European platform dedicated to promoting the cultivation and use of poinsettias organizes educational events in various cities. In Madrid, for example, International Poinsettia Day was celebrated in the central square of a well-known market, where poinsettias were distributed free of charge. more than five hundred plants.
During these days, hundreds of people come not only to take a flower home, but also to Listen to expert advice about maintenance, decorating tips, and botanical curiosities. The space is adapted for the occasion with a stage full of poinsettias, reinforcing the idea of the plant as undisputed icon of Christmas in European households.
Organizations like SfE often emphasize that the poinsettia is something more than a one-off decorationTheir presence is associated with the warmth of home, tradition, and color during a time when the days are shorter and colder. At the same time, these events highlight the economic importance of cultivation in countries like Spain, where production reaches several million units per year.
These types of campaigns are complemented by messages that encourage choosing quality plants, not treating them as a single-use object, and better understanding their extended life cycleWith proper care, the poinsettia can survive for many years and regain its colorful bracts every December.
How to choose a healthy poinsettia at the store
Much of the success with this plant begins before you even get home. Gardening experts agree that Choose the right poinsettia at the time of purchase This is essential if you want it to last beyond the holidays. Its outward appearance, while striking, doesn't always reveal the plant's true condition.
Poinsettias are sold in many stores. wrapped in decorative plastic with Christmas motifs. That eye-catching wrapping can hide broken stems or damaged parts. That's why it's recommended, whenever possible, carefully lower the plastic to check the internal condition of the plant before going to the checkout.
It's important to make sure the foliage is dense and without yellow leavesThe bracts should be firm and the small central flower buds—yellowish-green in color—should still be closed. This combination indicates that the plant is thriving and will have a longer decorative period.
Another key point is to check that the stems are securely fastened and without breakageThe poinsettia has particularly fragile stems: sometimes a sudden movement is enough to break them, even if they remain green for a few days. If several stems have been damaged, we may find the following when we remove the plastic at home: fewer live branches than we thought.
It's also important to avoid plants that have been exposed to cold drafts or left out in the open at the shop door. Cold damage may not be obvious at the time of purchase, but will appear later with drooping leaves or limp bracts right in the middle of Christmas.
Transport and placement at home: light, temperature and silent enemies
Once the choice has been made, the next challenge is bring the poinsettia home without damaging itSince the stems are brittle, it's best to hold it securely during transport, avoid excessive swaying, and protect it from bumps. If the outside temperature is very low, it's preferable to cover it with a bag or paper to reduce thermal shock.
Once at home, the location where it's placed will greatly influence its survival. Even when used as a houseplant, the poinsettia... It is still a kind of exterior that adapts to the interior temporarily. It needs lots of indirect natural lightTherefore, it usually works well near a bright window, always avoiding direct sunlight which could burn the leaves.
Regarding temperature, specialists recommend keeping it within a range of 18 and 22 ° C During the day, it's warmer, and somewhat cooler at night, around the 16 ° CIdeally, it should not be placed near radiators, stoves or fireplaces, as excessively hot and dry air causes rapid dehydration and premature falling of leaves and bracts.
You also need to be careful with drafts when ventilating. Opening the windows is necessary, but placing the poinsettia directly in the draft can lead to problems. wilted leaves and early fallA well-ventilated and bright room, but with the plant protected from direct air currents, usually gives good results.
A lesser-known but very relevant factor is proximity to certain fruits. Apples, bananas, and tomatoes emit [something - this phrase is unclear and likely a typo or error]. ethylene, a natural ripening gas which accelerates aging processes in plants. If we place the poinsettia very close to a full fruit bowlIts bracts may lose color and vigor prematurely, even if the rest of the care is correct.
Watering, substrate and care schedule
Regarding water, the golden rule with poinsettias is avoid overwateringLike many euphorbias, it doesn't tolerate waterlogging well: the roots rot easily if the substrate remains saturated. It's best to check the soil with your fingers and water only when the top layer is dry.
In a typical winter interior, with a moderate temperature, it is usually enough to a couple of waterings a weekAdjusting the frequency according to the ambient temperature. If the pot has a saucer, avoid letting water accumulate for hours, always removing any excess a few minutes after watering.
Rainwater is a good option, but if that's not available, tap water can be used. letting it rest for at least 24 hours so that some of the chlorine evaporates, thus reducing potential stress on the roots. Another technique that works well is the immersion irrigation: submerge the pot in a container of lukewarm water for about 15 minutes, let it drain and avoid leaving the substrate dripping.
If you decide to transplant the poinsettia, it is advisable to use a light and well-drained substrateThe soil should be enriched with some organic matter but not excessively compacted. Prolonged excess moisture quickly leads to yellowing leaves, bract drop, and even rot at the base of the stems.
To extend its life beyond Christmas, it is helpful to follow a small care scheduleDuring the winter months and well into summer, the plant should be kept with moderate watering, good light, and a stable temperature. In spring, it is recommended prune the branches by half to encourage more compact growth instead of an excessively tall and lanky stature.
How to make it turn red again year after year
One of the most frequent questions is whether the poinsettia can recover their red bracts in the following Christmas. The answer is yes, but it requires some planning and consistency. The reddening is due to the fact that, with long periods of darkness, the plant reduces its chlorophyll production and the red anthocyanins remain visible.
To achieve this, after spring pruning and a possible repotting with suitable substrate, it is necessary to keep it healthy throughout the year. From SeptemberThe plant begins to be exposed to increasingly longer periods of darknessby placing it in a completely dark place or covering it for several hours a day.
In autumn, between October and NovemberThe aim is for those light-free phases to reach a certain 12 to 14 hours of darkness per dayThis photoperiod management triggers the coloration of the bracts in preparation for December, when the plant once again displays the appearance that has made it so popular.
If these timings are respected and stress from sudden temperature changes is avoided, the same poinsettia can accompany for several years Christmas decorations, even growing into small shrubs if grown outdoors in sheltered, mild climates.
When problems arise, such as yellowing or wilted leaves, it's best to remove only those that come off easily, without pulling on those that are still resisting to avoid unnecessary damage. Sometimes, a simple change of soil or a slight improvement in fertilization with a balanced fertilizer is enough. revitalize the plant.
Toxicity and living with pets
One aspect that should not be overlooked is the Poinsettia toxicity for dogs and catsAlthough not usually fatal, its milky latex can cause symptoms in pets such as excessive drooling, nausea, vomiting, mild diarrhea, or irritation of the mouth and gums. The eyes can also be affected by direct contact, with possible redness or conjunctivitis.
Smaller animals, such as cats, puppies or rabbitsThey are especially vulnerable, so the wisest course of action is to place the plant out of their reach and watch them to make sure they don't chew on it. In case of repeated ingestion or the appearance of any noticeable signs, it is advisable to consult a veterinarian.
This contrasts with other winter plants, such as the so-called christmas cactus (Schlumbergera truncata), which is considered much safer for living with pets, as it does not contain dangerous toxins. In any case, even if a species is considered non-toxic, it can always cause mild digestive discomfort if ingested in excess.
A Christmas icon that goes beyond simple decoration
Between the history that connects it to Mexico, its consolidation as a symbol in Europe, the millions of copies produced each year, and its massive presence in homes, businesses and public spacesThe poinsettia has rightfully earned a central role in Christmas. Behind every pot lies careful work in greenhouses, municipal planting campaigns, educational projects with schoolchildren, and technical recommendations to ensure it arrives home in the best possible condition.
Knowing how to choose a good specimen, transport it without damage, avoid extreme heat and cold, control its watering, keep it away from fruit bowls overflowing with ethylene, and understand its pruning schedule and photoperiod transforms the poinsettia into something more than just a seasonal decoration. When this knowledge is combined with responsible use in streets and squares, respecting public plantings and the work of those who care for them, the poinsettia goes from being an impulsive December purchase to a plants to give as Christmas gifts that can accompany many Christmases.
