Basil, sweet whole:

Basil has many varieties (spicy globe, Italian, Greek, sweet, etc.) each with a distinct bright flavor, but on the whole they taste similar and are pretty much interchangeable in recipes.  Basil is fantastic used fresh on salads, bruschetta, in soups, sauces, etc.  Dried basil is a decent substitute.  Used heavily in Italian cooking
Suggested uses:  Italian sauces, nearly any soup, great in salad dressing, or fresh on salad.  Excellent paired with fresh tomatoes and fresh Mozzarella.
