It is hardy to zone five, but is prone to disease and insect infestation in the deep south. Southern gardeners may want to grow thyme indoors in containers so that conditions may be carefully controlled. Most varieties grow to only six to twelve inches in height, and they make an attractive edging for the perennial border. Leaves are dark gray-green in color, and pale pink flowers bloom at the tips of the stems in summer. You can start thyme from seeds to get a wider selection of varieties.
Most nurseries carry transplants in spring and summer.
It prefers a sandy, dry soil and plenty of sun. If your soil is acidic, add some lime. If you live in a very cold climate, protect the plants in winter by mulching heavily. Once established, the only care will be regular pruning of the plants and removal of dead flowers and pruning to remove old wood. Harvesting Leaves can be harvested for fresh use throughout the summer, but the flavor is best just before flowering.
