Poisonous Holiday Plants ? Or Urban Legends? « The Wired Gardener

a post from Jessica Story, Meadowbrook Farm

Poinsettias are NOT poisonous, they are the most studied decorative plant ever and no toxic effects have been found. In 1919 a 2 year old child of an army officer was found dead under a Poinsettia tree in Hawaii with poinsettia leaves in her hand. The investigation cleared the plant, but the record was never set straight and it has become an urban legend.

In nearly 23,000 recorded cases of Poinsettia ingestion, no life-threatening effect has ever been reported. The equivalent of a child eating over 600 leaves was tested and found to have little or no effect. Vomiting and diarrhea, while unpleasant, is the most likely result for a child or animal that did consume the leaves.

Interesting note-the Poinsettia and the Pennsylvania Horticultural Society have a long history together-the first public introduction of the plant was at the first Pennsylvania Horticultural Society Flower Show in 1829)

Like a number of common houseplants, many common holiday plants are mildly toxic, but are so foul-tasting that ingesting enough to cause harm would be difficult. Holly and Mistletoe probably pose the most risk, because the berries can be swallowed whole. Jerusalem Cherry is extremely toxic and should be avoided in households with young children. Ornamental peppers may cause discomfort like any other hot pepper, but are not toxic.

Other common “toxic” holiday plants (safe to use, just use common sense too!)

Poinsettias, pines and presents

Christmas is right around the corner and shoppers are out in record numbers. Folks are almost obsessed with getting their trees, poinsettias and gifts for family and friends. If you enjoy giving living plants for Christmas, consider giving poinsettias.

Last week, Russell Nagata wrote about the history of poinsettias. Today, let’s focus on purchase, propagation and care of this amazing plant.

Poinsettias, especially in Kona, are in spectacular color now. Although mainland folks think of the poinsettia as a Christmas flower, for us it blooms from late October through March. So if you don’t have a showy supply in your home and garden, now’s the time to start looking for them on the market.

Purchasing potted stock from a garden center or nursery is the easiest way to establish plantings of the holiday ornamental. However, some green thumb operators scavenge the neighborhood for hardwood cuttings when fellow gardeners prune their poinsettias following the flowering season. Getting plants this way can make you feel like a turkey if you choose cuttings from disease infected plants. If you get healthy plants, you can be sure to avoid “fowl” play.

There are a number of poinsettias available. They come in traditional reds or you can enjoy color combinations indoors and in the garden if you mingle the red plantings with white and pink varieties.

Poinsettia: It’s all about the leaves

by Russell T. Nagata

If it weren’t for the highly colored leaves, the poinsettia would be best known by some other name. Its scientific name, Euphorbia pulcherrima, literally means “most beautiful Euphorbia.” The true flowers of the poinsettia are called cyathia and are the green and white beads tipped with yellow and red in the center of the flowers. The showy parts of the plants are actually modified leaves called bracts.

The poinsettia grows wild in southern Mexico and naturally blooms under the shorter daylight hours of the fall season. The Aztec name for this plant was cuetlaxochitl and was use in many ways. A purplish dye was extracted from the colorful bracts to be used in textiles and cosmetics and the latex sap was used to treat fevers.

The plant was introduced into the United States by Joel Poinsett, the first U.S. ambassador to Mexico from 1825-29. Although trained in the medical profession, Poinsett’s real love was botany. On a trip to the Taxco area in 1828, he collected the brilliant red flowering plants and grew them at his South Carolina farm. He distributed the plants to friends, who distributed it to their friends and so on. It’s easy to see how the name originated.

Poinsettias – Symbols of the Holiday Season

It just wouldn’t be Christmas without the poinsettia. And in case you have forgotten your poinsettia facts since last year here’s a refresher on what you need to know about this festive plant.
Whether poinsettias are in the traditional velvety red color or any of the new streaked, spotted or dyed forms of plum, peach, blueberry, orange or cranberry colors, these plants help set the stage for a great holiday celebration.

For all the cheer that poinsettias bring, there are still some people that look upon this festive plant as poison. Stop, let it be said up front — poinsettias are not poisonous! This myth started almost ninety years ago in Hawaii and amazingly still continues to this day. Apparently an Army officer’s two-year-old child died after supposedly eating a poinsettia leaf. The Physician who made the diagnosis later realized he had identified the wrong plant. He had planned to return to the mainland to correct his error when he suddenly died (unrelated to poinsettias) and the story spread and spread. Although it was later determined to be a case of incorrect plant identification, many people still believed that poinsettias are poisonous.

As recently as 1995, sixty-six percent of people surveyed by the Society of American Florists believed that poinsettias were poisonous even though there was a lot of evidence to disprove this myth. Researchers at Ohio State University tested the effects of ingesting high doses of leaves, stems and sap and found the plant non-toxic.

Overnight red a good sign for Growing Greens

KAPA‘A — Almost overnight, everything turned red, said Marit McHugh, manager of Growing Greens Nursery in Kapahi.

“It was starting to turn, we had some signs of red, and all of a sudden, it’s all red,” she said Friday. “It must be the weather.”

McHugh was talking about the 2010 crop of poinsettia which is scheduled to start shipping next week to various commercial outlets, malls, churches and people with standing orders.

This year’s crop included about 5,400 plugs that were brought in August and raised at the Kapahi location. Now that they are in bloom with the holidays looming, the deliveries will start going out.

“This isn’t the biggest crop we’ve had,” McHugh said. “But then, the economy dictates what we need to do. Our best year, we had about 8,000 plants going out.”

Included among her plantings is “Ice Crystal,” a new variety brought in last year that has proven to be a solid seller, McHugh said.

“We brought in just a few last year and people grabbed them up almost immediately,” she said. “This year, we’ve brought in a few more and, already, half of the crop is going to Marriott’s Waiohai Beach Club and some of the jewelry shops around the island. We’ve also put some in lava rock for decorations.”

The lava rock poinsettias are something new Growing Greens is trying out this year, the plugs being placed into specially drilled-out lava rock and growing bonsai-style.

Chaconia/Wild Poinsettia,

When I lived in Hawaii one of my favorite trees was the chaconia or Wild poinsettia, Warszewiczia coccinea. I have been trying to locate this tree on the mainland and am not having a very easy time. Does anyone know of, or have one themselves, that I could purchase?

Thanks much-

I have only ever seen poinsettias near christmas time. I live in the north where they aren’t landscape plants though so maybe you could find them at a local nursery.
