Thymus serpyllum, commonly known as wild or creeping thyme, is dwarf evergreen shrub with woody stems and taproots. Thymus serpyllum belongs to the mint family, Lamiaceae and is native to Europe and north Africa. In its native range, Thymus serpyllum can be found growing in sandy and rocky soils. Thymus serpyllum is known to be able to creep 6-12 inches wide per plant. The leaves of the plant are small with rounded tips and oppositely arranged up square stems. Thymus serpyllum typically blooms in late spring to early summer with fragrant tube-like flowers that range from white to pink in dense clusters at the tips of each stalk. Thymus serpyllum is grown as an ornamental, edible, and medicinal crop. This species is perfect for ground covering needs while also providing culinary herbs for flavoring. The foliage may also be used to make teas that are known to have antiseptic, antifungal, and antibacterial properties. Thymus serpyllum grows best in full sun to partial shade, sitting in well-draining soils. Water the plant adequately during summer and sparingly during the winter. It is a drought-tolerant species and can tolerate a wide range of temperatures. Allow the soil to completely dry out in between waterings. USDA plant hardiness zones 4a to 9b.
Thymus serpyllum seeds benefit from a period of cold stratification to break dormancy. Place the seeds in a moistened paper towel or a mixture of slightly damp peat moss and vermiculite. Seal them in a plastic bag and refrigerate for 2 to 4 weeks. Next, seeds should be sown on top of potting mixture and lightly covered with a thin layer of sand or potting mix, just enough to cover the seeds. Germinating pots should be kept indoors out of extreme light and heat. Ideal germination temperatures range from 60°F to 70°F. Germination typically takes 1 to 2 weeks to occur. Even with optimal conditions, germination may be slow and sporadic.
