St. Paul, Minn. (December 3, 2001)—The poinsettia may be a popular plant to buy during the cold and snowy holiday season, but it’s actually a tropical plant with origins in Central America and Mexico. Now cultivated in greenhouses through out the U.S., the poinsettia starts out in summer as a rooted, stem cutting, then is induced to develop the colorful flower bracts by short day growing conditions in late fall and early winter. This long production period, say plant health scientists, can make it a tricky plant to keep healthy. Fortunately, the modern version of the plant is pretty hardy, and along with proper care can remain beautiful even after the holidays.
“There’s really no reason why people can’t continue to enjoy the beauty of this plant for many weeks after the holidays,” says D. Michael Benson, a plant health scientist at North Carolina State University in Raleigh. Benson, along with other scientists, work closely with growers to combat several diseases that routinely threaten the plant. The poinsettia, says Benson, is a small miracle of sorts, having not only survived the transition from a tropical tree to a domestic plant, but also the many diseases that could have prevented its cultivation in this country.
Benson offers some simple advice for keeping poinsettias thriving:
