Thymus serpyllum, commonly known as Wild Thyme or Creeping Thyme, is a low-growing, perennial herbaceous plant native to Europe and parts of Asia. It is a member of the mint family (Lamiaceae) and is prized for its aromatic foliage, tiny flowers and spreading growth habit. Creeping Thyme spreads by sending out runners or stems that root along the ground, allowing the plant to cover large areas relatively quickly. It typically grows to a height of 2 in. to 4 in. and can spread several feet wide, making it an excellent ground cover for sunny, well-drained areas. Thymus serpyllum is hardy in USDA zones 4 through 8, though some varieties may be more cold-tolerant than others. It is capable of withstanding both cold winters and hot summers within this range, making it adaptable to a wide range of climates. Creeping Thyme thrives in full sun and prefers well-drained, slightly alkaline soil. It is drought-tolerant once established and does not require frequent watering. In fact, it can be susceptible to root rot if planted in overly wet or poorly drained soil. This plant is well-suited for rock gardens, slopes, between paving stones, or as a low-maintenance ground cover in sunny borders. Creeping Thyme has a variety of uses in the landscape. It is often used as a ground cover to suppress weeds, prevent erosion and add color and texture to garden beds. Its spreading growth habit also makes it suitable for planting between stepping stones, in rock gardens, or along garden borders.
