To get the most out of your poinsettia, treat it like the tropical plant it is

If you’ve watched the classic TV version of “Frosty the Snowman,” your heart probably sank when he stepped out of the cold and snow into a warm greenhouse.

He melted in the heat, only to come back to life when Santa opened the greenhouse door and let a cold draft of air in.

What you may not have noticed was that the greenhouse was filled with red poinsettias. For them, a cold draft is a dangerous thing.

“Poinsettias don’t like the cold, so you want to keep them away from drafty doors,” said Geoff Royer, Royer’s vice president of central operations.

The juxtaposition of poinsettias, also known as “The Christmas Flower,” with cold and snow belies the fact that they are tropical plants, native to Mexico and Central America.

You must treat them as such if you want to get the most out of your poinsettia this holiday season.

National Poinsettia Day

Of course, December is synonymous with Christmas, but Dec. 12 is National Poinsettia Day. It commemorates the 1851 death of Joel Roberts Poinsett, the first U.S. ambassador to Mexico and the man after whom poinsettias are named.

Poinsett introduced the plant to the United States in 1825, sending samples to friends in his native Charleston, S.C. Poinsettias made their public debut at a Philadelphia flower show in 1829.

For their first hundred years in America, poinsettias were mostly sold as cut flowers. That was until Paul Ecke, a southern California agriculturalist, created varieties that could be shipped in pots.

Poinsettias registered sales of $213.7 million last year, according to Axios, up 40 percent from 2020.

Care tips

But for all the popularity of poinsettias, how to care for them remains much less well known and bear repeating. In fact, we go over poinsettia care tips with our own staff in the lead-up to every holiday season.

Unless you want to end up on someone’s naughty list, here’s what else you need to know to ensure your Christmas Flower lasts well into the new year.

  • Average room temperature is fine. Poinsettias can’t tolerate cold (including icy water) and can suffer from droopy leaves (a condition known as epinasty) if exposed to cold temperatures.
  • Epinasty also can result from a build-up of ethylene gas. Big-box retailers are notorious for leaving poinsettias in plastic sleeves, which trap ethylene and essentially ruin the plant.
  • Bright, ample light is best for the plant, mimicking conditions in Mexico.
  • Keep the plant moist but not sitting in water. Like people, poinsettias don’t like wet feet. The frequency and amount of water will vary depending upon the amount of sunlight, humidity and pot size to which the plant is exposed.
  • Poinsettias are sensitive plants, so you want to avoid banging them into things as they can bruise easily.

We wish you and your family a Happy Poinsettia Day and a Merry Christmas!

Here’s a handy guide to your Christmas poinsettia


Poinsettias have been called the lobster flower and flame leaf flower. By any name, they are the Christmas flower, although their flowers actually aren’t the colorful parts for which they are known.
But like an eager child who hasn’t made a wish list yet can’t wait to open gifts on Christmas morning, we’re getting ahead of ourselves.
First, some poinsettia background:

  • Native to Mexico, poinsettias are perennial shrubs that can grow 10 to 15 feet tall.
  • Poinsettias were introduced to the United States in 1825 by Joel Roberts Poinsett, the first U.S. ambassador to Mexico.
  • Dec. 12 is National Poinsettia Day in America, marking Poinsett’s death in 1851.
  • Poinsettias were first successfully grown outside Mexico by Bartram’s Garden in Philadelphia, a 50-acre National Historic Landmark that still operates.

Some people pronounce it “poinsetta” (three syllables), and others say “poinsettia,” (four syllables). We’re not sticklers either way. It’s more important that you enjoy your poinsettia and get the most out of it.

Grown in Lancaster County

But while there’s leeway when it comes to pronunciation, there are strongly rooted facts about poinsettias:

  • The colored parts of poinsettias aren’t flowers but bracts (leaves).
  • Poinsettias come in more than 100 varieties, from traditional red and white to pink and burgundy, marbled and speckled.
  • Poinsettias are commercially grown in all 50 states. Royer’s are from Lancaster County, Pa.
  • Ninety percent of all poinsettias are exported from the United States.
  • Contrary to popular myth, poinsettias are not poisonous, to humans or pets: An Ohio State study found that a 50-pound child who ate 500 bracts might have a slight tummy ache. Some people with latex allergies have had skin reactions to the sap that comes from poinsettia leaves.

Poinsettia care

Royer’s offers decorated and undecorated poinsettias in multiple color and size options.
Poinsettias are happiest in conditions that approximate their Mexican origin: as much bright light as possible, warm and never sitting in water. Like humans, they don’t like wet feet.
The plants can suffer from droopy leaves, a condition known as epinasty, if they are exposed to cold temperatures or experience a build-up of ethylene gas.
If you’ve ever shopped for poinsettias at a big-box retailer, you may have seen a rack of them still in their protective sleeves. What you’re really seeing is those plants being ruined because the sleeves trap ethylene gas. An experienced florist knows to remove the sleeves as soon as possible.
By any name or pronunciation, poinsettias are a beautiful and safe holiday tradition, a gift of Mexican origin that keeps giving to the world nearly two centuries later.
