"Thymus praecox is a species of thyme. A common name is Mother-of-Thyme; "creeping thyme" and "wild thyme" may be used where Thymus serpyllum, normally called thus, is not found. It is native to central southern, and western Europe.
Thymus praecox is cultivated as an ornamental plant, used as an evergreen groundcover in gardens and pots. When maintained at a lower height it is used between paving stones in patios and walkways. It is drought tolerant when established.
This thyme species (and Thymus serpyllum) has escaped cultivation in North America, and is a weed or invasive species in some habitats in the United States."
