New Hybrids Promise To Rock Your Poinsettia World


New hybrids are changing the poinsettia world

December 12 is National Poinsettia Day, the day Americans honor the plant that has become a symbol of the holiday season. And while not everyone’s a fan, it’s hard not to marvel at the species’ growing popularity. Poinsettias have come a long way since they were first introduced to the United States by Joel Roberts Poinsett. Back then, they were celebrated for their brilliant red color. These days, they come in every shade of white, pink, orange and even blue.


While they are now commonplace in the United States, poinsettias (Euphorbia pulcherrima) are actually native to Mexico. In their natural habitat, they thrive in the moist, humid environments of the tropical forest. Unlike today’s compact varieties, though, native poinsettias are sprawling and vine-like. And they often develop into a small tree or shrub.

Due to their bright red color, poinsettias have been a part of Christmas celebrations in Mexico since the mid 1600s. But in the U.S., the plants were virtually unheard of until the early 1800s. This is when Poinsett, the first U.S. ambassador to Mexico, stumbled upon some while stationed in the country.


Poinsett, in fact, was so struck by the remarkable species that he took cuttings and sent them home to his family in South Carolina. When he later returned to the States, he started propagating the plants on his own. In time, Poinsett began introducing his specimens to gardens and nurseries throughout America.

As their popularity grew, poinsettias became known as the ‘Mexican Fire Plant.’ Just as in Mexico, their scarlet, star-shaped leaves and winter blooms made them a natural addition to holiday households. The plant was eventually renamed poinsettia in honor of its discoverer.


Although they look like flowers, poinsettias’ bright red ‘petals’ are in fact modified leaves. The plant’s actual flowers are the tiny cluster of yellow spheres in the poinsettia’s center. In order to produce the colorful bracts, poinsettias require a daily diet of at least 12 hours of darkness followed by a period of bright sun. This is a long process undertaken by the grower.

During the 1800s, poinsettias remained pretty much a greenhouse curiosity. It wasn’t until the early 1900s that growers began experimenting with additional colors. Then in the 1960s, the introduction of more compact varieties led to mass production and marketing of the holiday ‘flower.’

Today, in addition to traditional red, you can now find the plants in every shade of salmon, pink, yellow, orange and white. There are also a growing number of marbled and striped varieties. And there are more than 100 new cultivars in development.


One of the best places to view the newest varieties is the U.S. Botanic Garden, located just off the grounds of the United States Capitol. Not only are there interesting specimens grouped by color in the entry foyer (part of the DC Landmarks Display), but there are also native Mexican species growing wild in the garden’s atrium.

But the real surprise awaits in the rear of the garden. There, in a sun-splashed hall adjoining the restrooms, around 50 unusual varieties are on display. These are part of the U.S. Botanic Garden’s own private collection. 

Following are some of the standouts from the 2018 exhibit.

Traditional poinsettias are selections of Euphorbia pulcherrima. But a process patented in 2003 has allowed growers to cross Euphorbia pulcherrima with Euphorbia cornastra to create some spectacular hybrids. Many of these new varieties feature much smaller central flowers, placing the focus more on the colorful bracts. Below are some more great examples from the U.S. Botanic Garden’s collection.

When shopping for a poinsettia, make sure to look for a plant that has dark green foliage all the way down to the soil line. And choose plants that have fully-colored bracts and no green around the bract edges. Green edges are a sign that the plant is older and won’t last as long. Most importantly, never buy plants with yellowed leaves, which are sure signs of plant stress.

Although bred to be compact, poinsettia branches break easily. Check to make sure the foil sleeve is not holding up cracked branches. And always remove the sleeve after purchasing. The plants need plenty of air circulation to survive.

Finally, water your plant well and allow it to dry out before re-watering. And avoid fertilizer, which will hasten the decline of the colored bracts. Remember to give your poinsettia plenty of sunlight to help it maintain its bright color.


Although the sap and latex of the poinsettia leaves can cause a mild allergic reaction in some sensitive individuals, the plants themselves are not poisonous. As for the commonly-held belief that the plants are toxic to pets, the Pet Poison Helpline confirms that while poinsettias are listed as toxic to dogs and cats, they are only mildly irritating to the mouth and stomach if swallowed.


Poinsettia is traditionally capitalized since it is named after a person. According to the Oxford Dictionary, it is pronounced poin-set-ee-ah.
