POINSETTIA LEAF

Poinsettias are famous as the Christmas plant because of their bright red and greeen leaves.
Joel Robert Poinsett, first U. S. ambassador to Mexico who obtained plants from the wilds of southern Mexico, introduced it to the United States in 1825. The common name for the exotic plant, poinsettia, came from his last name. Botanically, the plant is known as Euphorbia pulcherrima.
This is the last red leaf left on our Christmas Poinsettia as it has been sitting in the sun causing the leaves to revert to green.
