There are dozens upon dozens of plants that you can pair up with others as you plan your garden. Just think about the needs of the plants and what already does well in your area!

One of the things that you should be sure to avoid when pairing plants is putting a spreading groundcover around other plants. Herbs like mint, marjoram, and oregano can tend to choke out the roots of other plants that it is coupled with and can become a serious issue in the garden if not kept in control. I often like to put these in containers on their own to help ensure that they will not become an issue for my other garden plants.
