Christmas colour

These are festive poinsettias.

Found this information about them on the Web: "poinsettias were first introduced in the United States in 1825 by Joel Roberts Poinsett. While serving as the first United States Ambassador to Mexico, he visited Taxco and found the flowers growing on the adjacent hillsides. By an Act of Congress, December 12 was set aside as National Poinsettia Day. The date marks the death of Joel Roberts Poinsett who died in 1851."
