Golden Thyme DNA Study
In 1999 Dr. Madan Thangavelu and I carried out the Golden Thyme DNA Study, as a result of which our native
golden leaved thymes were placed in T. pulegioides rather than T. citriodorus in which they had
mistakenly been placed because the leaves were lemon scented.

DNA profiles for the Golden Thyme DNA Study, demonstrating that the golden leaved lemon
scented thymes (Group 4) belong in Thymus pulegioides (Group 6) and not in Thymus citriodorus (Group 3).

Tree based on DNA profiles from the Golden Thyme DNA Study, demonstrating that Thymus
citriodorus and its cultivars are distinct from the species T. pulegioides and T. vulgaris
and that the lemon scented, golden leaved thymes belong in the species T. pulegioides.
