The History of Thyme: Know Before Growing Thyme

Thyme or Thymus vulgaris is from the family Lamiaceae and is native to the Mediterranean area. The first recorded use of thyme was in the first century AD. Sumerian cuneiform tablets (not our electronic kind) from 2750 BC show thyme being dried and ground with certain fruits and water for use as a poultice.

Thyme is an important herb for both culinary and medicinal uses; thyme was once used by the Egyptians in their embalming process. Romans used thyme on their floors to keep away venomous creatures. 

The symbolism of thyme is courage; Roman soldiers bathed in thyme because they believed it would help them be courageous. Soldiers took thyme into battle to bolster their courage.

One way to do that is to grow your thyme in a planter or pot rather than in a bed with other plants that have different watering needs. Another option is to plant your thyme in the warm, south-facing bed and keep that soil drier than other areas of the bed as thyme is drought tolerant.

Many people prefer buying a thyme plant or starting with cuttings as growing thyme from seeds is a long process. If you do want to start thyme from seeds they should be planted 1/4″ deep and the plant will not be mature until it is two years old. Thyme grows to a width of 12–18″ and can grow between 5–12″ tall.

Thyme watering needs are very light. In fact, if you water thyme too much it is susceptible to rot or mildew. Thyme prefers dry, well-drained, rocky soil since it is drought tolerant.
