Lemon thyme is a favorite of mine for container combinations because of its bright color and refined texture. When bruised, the leaves smell so citrusy you will swear someone has just squeezed a lemon.
Growing thyme in containers enables you to reproduce the well-drained soil conditions of the Mediterranean slopes where it grows wild. Since the soil in my garden is largely heavy clay I have to use caution when planting anything that requires good drainage. For instance, all of the Mediterranean herbs are a challenge for me to grow. Even a plant as durable as thyme can be a total bust if I don’t set the plant up for success by amending the soil with plenty of sand and pea gravel to minimize the effects of excessive moisture. Lemon thyme is evergreen, but when it really gets cold I try to cover the plants with frost blankets to preserve the foliage and help the plant winter over.
