Etymology

Origin of poinsettia

1830–40; < New Latin, named after J. R. Poinsett (1799–1851), American minister to Mexico, who discovered the plant there in 1828; see -ia

Explanation

The bright red potted plants you see everywhere at Christmastime are called poinsettias. This plant is so commonly associated with the holiday that it's also known as Christmas Star. Poinsettias come from Mexico, and they get their name from Joel Roberts Poinsett, the United States' First Minister to Mexico in the 1820s. Besides unsuccessfully attempting to acquire new U.S. territory from Mexico, Poinsett was an amateur botanist who admired the brilliant red and green Flor de Nochebuena, or Christmas Eve flowers. His success lay in introducing the poinsettia to North America.
