Poinsettias at Christmas
A Poinsettia flower
Poinsettia plants are native to Central America, especially an area of southern Mexico known as 'Taxco del Alarcon' where they flower during the winter. The ancient Aztecs called them 'cuetlaxochitl'. The Aztecs had many uses for them including using the flowers (actually special types of leaves known as bracts rather than being flowers) to make a purple dye for clothes and cosmetics and the milky white sap was made into a medicine to treat fevers. (Today we call the sap latex!)
