Poinsettias are popularly, though incorrectly, said to be toxic to humans and other animals. In 1944, the plant was included in H. R. Arnold's book "Poisonous Plants of Hawaii" based on this premise. In the 1970s, The Ohio State University's Department of Horticulture and Crop Science debunked the longstanding myth of poinsettias being poisonous. The research assured the public that poinsettias pose no threat, encouraging a reevaluation of the popular holiday plant.

Ohio State Assistant Professor Garrett Owen advises buyers to focus on personal preferences when choosing a plant, emphasizing color variations such as reds, whites, pinks, and novelties with variegated bracts. He stresses the importance of choosing a visually appealing plant with roundness and well-branched elegance.

The professor sheds light on the intricate stories behind poinsettia cultivars, revealing the global efforts of breeders who select genetics and traits for ornamental value. Additionally, practical tips for post-holiday care include placing poinsettias in sunny windows away from drafts and adopting a careful watering routine to prevent issues like root rot.

In 2019, the U.S. poinsettia industry was valued at an impressive $216.5 million, producing around 45 million points, according to industry reports.

As families prepare to adorn their homes with poinsettias, the plant once feared for its perceived toxicity is now celebrated as a symbol of beauty, resilience, and the enchantment of the season.
