The bright red flower called the poinsettia has become a traditional part of American Christmas celebrations. But the flower’s common name, which, while it sounds exotic, has nothing to do with the native name for the plant, is a reference to an American diplomat of whom a 1929 edition of the Baltimore Evening Sun wrote “His Career was as flamboyantly colorful as the poinsettia, and yet he is almost forgotten.”
Put simply, rats tend to go where humans go, and these strange bedfellows have had a surprising impact on each other.
