How Did the Mexican Weed Poinsettia Become Associated With Christmas?

One hundred years ago, Dr. Joel Poinsett, the American ambassador to Mexico, introduced the Poinsettia plant to the rest of North America.

A Mexican legend has it that two poor children had nothing to offer the baby Jesus during the Christmas festival.

So on their way to church they picked some green weeds from the road side.

When they placed them at the nativity the green petals turned a bright red in the shape of a star.
