Where does the poinsettia come from? Where was this traditional Christmas plant discovered? Are poinsettias poisonous? Learn more!

No plant symbolizes Christmas quite like the poinsettia. More than 2 million of them will be sold this year, making it the largest potted flower crop grown in the US.

There are over 100 varieties of poinsettias available in shades of red, pink, white,and yellow—solids, streaked, marbled, and multicolored. It makes it hard to pick just one!

Some have even been treated with dyes, painted, or sprayed with glitter.

National Poinsettia Day, December 12, is coming up, so I took advantage of an open house at a local wholesale grower’s greenhouse to view the estimated 40,000 plants they have ready to be shipped out to stores in my region.

Imagine acres of poinsettias in all colors and sizes!

Poinsettia History

The poinsettia is a tropical shrub native to southern Mexico where it grows up to 10 feet tall. The colored “flowers” are actually specialized leaves called brachts, while the true flowers are inconspicuous beads found in the center of the brachts.

Joel Poinsett, the first U.S. ambassador to Mexico, was so impressed by the beauty of these plants that he sent cuttings back to his home in South Carolina in 1828. Soon the plants became popular across the U.S. and were named for him.

For over 150 years, December 12 was considered National Poinsettia Day to honor the day of Poinsett’s death in 1851. In 2002 an Act of Congress made it official.

Are Poinsettias Poisonous?

Let’s lay to rest the myth that poinsettias are poisonous. Years ago, researchers at Ohio State University fed huge quantities of poinsettia parts to rats with no ill effects. To replicate their test, a 50-pound child would have to eat 500 leaves.

That said, people with latex allergies can be sensitive to the milky sap and should be careful when handling the plants to avoid a rash. It’s still best not to have animals or children eating plants; the sap can cause an upset tummy and irritate the skin. Keep plants out of reach.

The USDA reports that it has no evidence of anyone dying from eating poinsettias.

On a related note, holly and mistletoe are toxic to children and pets. They will induce vomiting and diarrhea—and can even be fatal in large quantities.

How to Care for Poinsettias

To get off to a good start, protect your new plant from cold temperatures and chilling winds on the way home from the store. This is a tropical plant, so don’t leave it in a cold car while you run other errands.

At home, place it near a sunny window where it will get bright, indirect light for at least 6 hours a day. Keep it out of direct sun though, which could fade the leaves. Avoid drafts, keeping temperatures between 65 and 70 degrees. Overwatering is a common cause of death, so water when dry and don’t let the plant sit in water. No fertilizer is needed while the plant is in bloom.
