How to Keep Your Christmas Plant Alive

Every December, homes, shops, and streets fill with an intense red that announces the arrival of Christmas: the Poinsettia, also known as the Christmas Star or simply Christmas plant.
It is a symbol so deeply rooted in this season that it is almost impossible to imagine Christmas decorations without it.

But why has this plant become a Christmas icon? Where does this tradition come from? What curiosities does it hide? And most importantly: how can we keep it alive after the holidays?
At Som Menorca, we tell you all about it.

1. Why is the Christmas Star typical at Christmas?

The popularity of the Poinsettia has two main reasons:

Its intense, festive red color

During the winter months, the plant develops its famous red bracts (often mistaken for petals).
This vibrant color perfectly matches the Christmas aesthetic — red, green, and gold — making it an ideal natural decoration for the season.

Its flowering coincides with December

The Poinsettia is a short-day plant: when daylight hours decrease, its bracts change color.
The change from green to red exactly in December, right in the heart of the Christmas season, turned it into a symbol of the holidays.

2. Origin and Tradition: From Mexico to the World

Although it is now common in Europe, its story begins far away.

An Aztec symbol

The “Christmas Eve plant” originates in Mexico.
The Aztecs called it Cuetlaxóchitl and used it for natural dyes and medicinal preparations.

Its connection to Christmas

A Mexican legend tells that a poor girl had no gift to offer the Baby Jesus.
When she brought some green leaves to the nativity scene, they miraculously turned bright red.
Since then, the plant has been associated with the Christmas spirit.

The ambassador who made it famous

The Poinsettia arrived in the United States thanks to Joel Poinsett, the first U.S. ambassador to Mexico, who exported it to his country and popularized it.
This is where its international name, Poinsettia, comes from.

Its spread to Europe

In the mid-20th century, it was introduced to European nurseries and quickly became a Christmas decoration classic.

3. Curiosities You Might Not Know

The Christmas Star hides some very interesting details:

• The red parts are not flowers but bracts. The true flowers are small and yellow in the center.
• The color depends on the amount of light: for it to turn red, the plant needs long, dark nights.
• There are many colors: white, pink, yellow, marbled, or bicolor, although red remains the most traditional.
• It is more resilient than it seems but very sensitive to sudden temperature changes.
• Although it was traditionally said to be toxic, it is now known to be safe, though it can cause irritation if ingested or handled excessively.

4. How to Keep Your Christmas Plant Alive After the Holidays

The Christmas Star can live many months — even years — with proper care. Here’s a simple guide:

1. Control the temperature

• Ideal: 18–22 ºC
• Avoid: drafts, direct heating, and sudden temperature changes
  These variations are the most common cause of leaf loss.

2. Water moderately

• Water only when the soil feels dry to the touch.
• Avoid waterlogging.
• Tip: once-a-week immersion watering (submerge the pot for 10 minutes and let it drain).
  Too much water kills it faster than too little.

3. Light, but no direct sun

Place it in a bright spot near a window, but without direct intense sunlight.

4. Maintain light ambient humidity

If the house is very dry due to heating, lightly mist water around the plant (not directly on the red bracts).

5. After Christmas: How to Make It Turn Red Again

If you want it to color again the next December:

1. In spring, prune it to about 10–15 cm (4–6 inches).
2. Repot it into a slightly larger pot.
3. From October, it needs 14 hours of complete darkness per day for 6–8 weeks.
   (You can cover it with a box or place it in a closet in the evenings.)

This process activates its winter coloring.

The Christmas Star is not just a holiday ornament: it is a plant full of tradition, symbolism, and natural beauty.
With the right care, it can accompany you all year and add a Mediterranean touch of color to your home.

At Som Menorca, we love traditions that unite, decorate, and make a home.
