Some herbs that grow well together include Mediterranean varieties such as thyme, sage, marjoram, lavender, oregano and rosemary. These herbs share similar care requirements. They all need plenty of sunlight and dry, well-drained soil.
A gardener can also place moisture-loving herbs together such as tarragon, parsley, basil and cilantro. These herbs need plenty of water and full sun. When planting the herbs in pots or growing the herbs year-round, prepare to replant the parsley after two years, as it only lives that long.
Lemon-scented plants grow well together such as lemon verbena and lemon thyme. Lemon verbena is a large shrub that spreads out, so planting it in a single pot leaves only room for another small herb. Lemon thyme not only grows around the verbena's base, but it also helps to keep the soil moist.
Herbs in the mint family such as peppermint, spearmint, orange mint, lemon balm and catmint are closely related, but they do not work well together in pots. One reason is that they tend to spread out and grow sideways. A single type of mint plant needs to be placed in a long container or window box, which gives it room to grow. Also, mint plants interbreed, so planting them together creates hybrids.
