From CooksInfo.com: "In North America, Rocket is usually called Arugula. Many people think that is the Italian name, but it isn’t. The Italian word is for arugula “rucola” or sometimes “rochetta." “Arugula” is an English corruption of the word in some Italian dialect, perhaps from Lombardy where they call it “arigola.” "Eruca" is the Latin word for a variety of cabbage and the word rocket in English, German, and Italian. Yes, it's confusing!!!
