Here in Costa Rica it is called cilantro as is the small leaf variety. But it is distinguished from that by calling it cilantro coyote because it grows wild here like a weed. I'm delighted when I'm find one that has popped up in my yard. I use it just as a seasoning and I much prefer it to the other variety. I've never thought of using it as vegetable. How do you use it, in stir fries?
As an interesting aside, culantro is not a word that you want to use in Mexico. It is slang for a part of the body of a woman and not used in a complimentary way.
