The plant's association with Christmas began in 16th century Mexico, where legend tells of a young girl who was too poor to provide a gift for the celebration of Jesus' birthday. The tale goes that the child was inspired by an angel to gather weeds from the roadside and place them in front of the church altar. Crimson "blossoms" sprouted from the weeds and became beautiful poinsettias. From the 17th century, Franciscan friars in Mexico included the plants in their Christmas celebrations. The star-shaped leaf pattern is said to symbolize the Star of Bethlehem, and the red color represents the blood sacrifice through the crucifixion of Jesus.
Poinsettias are popular Christmas decorations in homes, churches, offices, and elsewhere across North America. They are available in large numbers from grocery, drug, and hardware stores. In the United States, December 12 is National Poinsettia Day.
Big Spring, Texas is well known for its poinsettias as the "lighted poinsettia capital". When the Comanche Trail Festival of Lights first began the dam at the big spring held four huge poinsettias made of rebar welded together in the shape of a poinsettia flower. Each flower was made up of 5 leaves. The leaves were decorated with red Christmas lights. The four poinsettia flowers were an awesome sight to see entering Big Spring from the south. Each year more flowers were added to the dam and inside the park until Comanche Trail Park has by 2006 added seven poinsettias, making a total of eleven lighted flowers on the dam and countless flowers inside the park, making Comanche Trail Park the Christmas Poinsettia capital.
