'Red-y' for the holidays. Poinsettia Day

Here's the red poinsettia, one of the plants synonymous with the holiday season across North America. With its striking star-shaped leaves, the poinsettia has become a symbol of Christmas cheer, brightening homes and public spaces during winter. National Poinsettia Day in the United States celebrates the legacy of Joel Roberts Poinsett, the first US ambassador to Mexico, who introduced these vibrant plants to America in the 1820s. He discovered them while exploring the Taxco region in Guerrero and, so taken by their beauty, sent clippings back to his home in Charleston, South Carolina.

The history of the poinsettia can be traced back to ancient civilisations. The Aztecs, who called it cuetlaxóchitl, used it to make a reddish-purple dye and treat fevers. But the plant's association with Christmas has roots in Mexican tradition, where it's known as 'la flor de Nochebuena' or 'Holy Night flower.' According to legend, a young girl, unable to afford a gift for Baby Jesus, was inspired to offer humble weeds, which miraculously transformed into the vibrant poinsettias we know today.
