Bright Indirect

The orientation of your window defines where to put your plant so it gets bright, indirect sunlight. If your window faces
North, place your plant between 0 and 1 ft away from it.
If it faces East or West, put it 1 to 5 ft away.
If it faces South, place it between 5 to 10 ft away, as sunlight from the South is the strongest.

In the language of the Aztecs, Nahuatl, the plant is called Cuetlaxochitl, which means ‘flower that grows in residues or soil.’ The story tells that a girl who was too poor to bring a gift to Church on Christmas gathered weeds to put on the altar. From the weeds, the Christmas Star blossomed!

Plant story

The Christmas Star, or Euphorbia pulcherrima, as its name indicates, blooms around Christmas time. Although its red, velvety leaves make it look like a flower, it is not. It does have flowers in yellow clustered buds in its center. The plant originates from Central America, from Mexico to Guatemala.

The Christmas Star is also commonly called Poinsettia after Joel Roberts Poinsett, who introduced the plants to the US in the 1820s.



Place of origin

Southern Mexico known as 'Taxco del Alarcon'

Care for your Christmas star like a pro!


Christmas star needs BRIGHT INDIRECT.

To place your plant in the perfect spot, let’s start with understanding how much light it needs and how much light your place gets. To figure this out, you need to find the direction of your window and measure how far the plant is from it. First, using the compass or map on your phone, see what direction your window faces: North, East, West, or South. Here’s what you need to remember:

  1. South-facing windows make for the brightest spots, then East- and West-facing, and then North-facing.
  2. If the window is in between two directions, use the least sunny direction as a base.
  3. Each window has an optimal proximity range. Here’s where to put your Christmas star, based on the direction of your window:
    • not possibl to place in a room with North Window, as not enough sun
    • within 1ft away from East or West window;
    • between 1-5ft away from South window;

Within this range, the closer your plant is to the window, the more light photons it gets, and the better it thrives.

Note: This is a general guideline. Each place is unique, and you know yours best. Is the window view obstructed by the trees and a highrise? Is there a sheer curtain? If so, less light is coming in. Move your plant closer!

Still not sure if your Christmas star will be thriving in the spot you picked?

Another simple way to define brightness levels is by measuring the intensity of the shadow. That’s particularly helpful if the view is somewhat obstructed and it’s hard to estimate how much light actually sneaks in. Place a sheet of paper on the spot where you’d like to grow a plant. Hold your hand about 1 foot (30cm) above the paper. Now, what do you see?

Christmas star is a HEAVY DRINKER.

Check your plant regularly, but only water it when it’s thirsty.

Every plant needs a period of drying for the oxygen to get to its roots. Overwatering damages your plant by preventing that process from happening. So how can you know how much water your
Christmas star
needs? The ideal watering frequency depends on the plant’s drinking habits and how fast the soil dries out in your unique indoor space, so it would be misleading to recommend a fixed schedule. To best meet your plant’s water needs, monitor it, and watch for the signs it’s thirsty.

Here’s how the how to:

Once a week before giving your plant a drink, check the moisture level in the pot by dipping your finger a couple of inches into the soil.

Heavy Drinkers
need to be watered when 1/2′ of the topsoil is dry.

The dislikes of Your Christmas star When It Comes To Water

  • Your Christmas star doesn’t like it when its roots are left sitting in water. They would start to rot and that would irreversibly damage your plant.

What to do: Make sure you always discard the drenched water from the pot or saucer after watering.


Christmas star comes from a Subtropical climate. Aim to provide the air conditions it would find in its natural habitat. At all times, maintain a comfortable room temperature of 55-65°F,13-18°C.

Christmas star
is a resilient and adaptable plant. It feels good in normal humidity (30-40%) but also tolerates low humidity (less than 30%), so it’s likely to enjoy your indoor space as it is.


To provide your Christmas star with the right nutrients, fertilize it from March to September.
It’s a HEAVY eater plant. As a rule of thumb, it should be fertilized once a month.

Liquid fertilizer with NPK formula 10-10-10 (Nitrogen, Phosphorous, Potassium) works best for it.

Otherwise, you can use all-purpose indoor plant fertilizer.

Never fertilize your plant during the winter or fall months. It goes through winter dormancy and its appetite naturally slows down.
