Greek Oregano: With a stronger, more aromatic flavor and scent than regular oregano, Greek Oregano is one of the most important herbs of Italian, Greek, and Mexican cooking. Greek Oregano is a must in Italian dishes, tomato sauces, pizza, fish, and salad dressing. Greek Oregano lives about five years as a useful culinary plant and longer as an ornamental. Greek Oregano is the true wild oregano found originally in Greece. Greek Oregano has a strong oregano aroma and flavor; the flavor stands up to bold flavors like tomatoes, onion, garlic, and beef. The low-growing plants have slightly furry, dark green leaves with white flowers.
