Cilantro, or Mexican parsley, looks like Italian parsley. The one distinguishing feature of Cilantro, is the scent. Parsley is not nearly as fragrant as Cilantro. Cilantro is sought after for it's unique flavor, which you can sometimes smell from several feet away. Cilantro's small leaves are dark green, grow in bunches, and the bottom half of the stem doesn't grow any leaves.
