Euphorbia pulcherrima
Poinsettia
The common name Poinsettia given to Euphorbia pulcherrima (Willd. ex. Koltsch) is a result of its introduction into the United States by Joel Robert Poinsett who, finding these plants growing on the hillsides near Taxco, Mexico sent plants to his home in Greenville, South Carolina shortly after assuming the office of first U.S. ambassador to Mexico in 1825. Poinsettias were grown commercially for Christmas sales in the latter part of the 19th century, and both propagation stock and young plants were offered for sale in the trade magazines of the early 20th century.

Growing and Maintenance Tips:
Light - Poinsettia's longevity is not affected by normal indoor light levels (50 to 100 fc). Avoid direct sunlight since plants will dry out rapidly and damage may occur on the bracts and leaves. Temperature - Maintain plants in cool (68° to 72°F; 20° to 22°C) areas. Location - Place plants near a window but out of direct sunlight. Irrigation - Keep plants uniformly moist at all times. If plants do become dry, it may be necessary to submerge the entire root system in water to thoroughly rewet the peat moss-based media. Drying out will greatly reduce the longevity of most cultivars. Grooming - Remove dead bracts as needed. Disorder - Faded bracts: Bracts that are just showing color when placed into the interior will develop into pale colored bracts. Only purchase plants with more open flowers, or place plants in higher light levels. Cultivars - A number of cultivars-most with excellent longevity-are available with red, pink, white and variegated bracts. Some differences exist in flower drop and sensitivity to drying out.
