Oregano, a plant from the mint family, is widely used across cuisines worldwide. Not only are they tasty, they're versatile and easy to grow. They can be planted next to almost anything, and are often used in gardens regardless of culinary use.
Direct sunlight 6-8 hours/day (indoor) or full sun (outdoor). Should be harvested right before or just as they flower.
Pro-tip: An easy way to separate leaves after harvest is to pinch the stem near its tip, then run your fingers down the length of the stem, from top to bottom.
