Frequently Asked Questions

Are poinsettias poisonous?

Poinsettias are not poisonous. For nearly eight decades, this rumor has continued to circulate because of one unfounded story in 1919: that an Army officer’s two year old child allegedly died after eating a poinsettia leaf. While never proved by medical or scientific fact and later determined to be hearsay, the story has taken on a life of it’s own. But, the defenders of the poinsettia have pulled out all the scientific stops to allay public fears.

The Society of American Florists (SAF) worked with the Academic Faculty of Entomology at Ohio State University (OSU) to exhaustively test all parts of the poinsettia (Euphorbia pulcherrima). OSU researchers established that rats exhibited no adverse effects – no mortality, no symptoms of toxicity, and no changes in dietary intake or general behavior patterns – when given even unusually large amounts of different poinsettia parts. The United States Consumer Product Safety Commission (CPSC) accepts animal tests as valid indicators whether any product or natural growth is harmful to human health.

The OSU research was conducted 23 years ago and other sources have continued to reinforce the poinsettia’s safety.

According to the American Medical Association’s Handbook of Poisonous and Injurious Plants, other than occasional cases of vomiting, ingestion of the poinsettia plant has been found to produce no effect.

After reviewing all available poinsettia related information, the CPSC denied a petition in 1975 to require warning labels for poinsettia plants. Despite its continued circulation, the myth of the poinsettia is gradually losing steam.

How do you get a poinsettia to bloom?

To get a poinsettia to reflower you have to keep it in total darkness between 5 pm and 8 am. Start this around October 1^st and continue until color shows on the bracts; usually around early to mid-December. Any little exposure to light can prevent flowering. Covering the plant with a light-proof bag and placing it in a closet might work. Night time temperatures above 70-75°F can decay or prevent flowering.

How can I make my poinsettia last during the holiday season?

I want to keep my poinsettia plants. When can I take them outside?

Move your poinsettia plant outdoors when all danger of frost has passed. Place it in a sunny area but where it will get moderate shade in the afternoon.

Should I fertilize my poinsettia if I am keeping it past the holiday season?

Fertilize once a month with a water soluble houseplant fertilizer.

How often should I water the poinsettia?
