Roses are so predictable – for a Valentine's Day more Addams Family than FTD, why not entice your love with a carnivorous, fly-eating plant? Bonus points for an erotic twist: Named for Venus, the goddess of love, Dionaea muscipula has a bit of a naughty secret. When John Bartram, the Royal Botanist to King George III for the North American Colonies, first sent a specimen back to Europe for further study, he nicknamed the plant "tipitiwitchet" or "Tippity Twitchet" because of its resemblance to human female genitalia. Mr. Bartram!
