This plant is cool for a lot of reasons. First of all … its name! In Homer’s Odyssey, the magical goddess Circe would invite men to a feast, but would lace the food with an herb which would drug them, then she would turn them into pigs. Early botanists decided that this was the plant and therefore named it Enchanter’s Nightshade and gave it the genus name Circaea. Plants have way better names than birds!
Far less interesting is the fact that the flowers have only two petals, although deeply cleft and look like four. There are only a very few species flowers that only have two petals.
