Golden Thyme DNA Study

In 1999 Dr. Madan Thangavelu and I carried out the Golden Thyme DNA Study, which demonstrated that our native golden leaved thymes should be regarded as Thymus pulegioides rather than T. citriodorus.

Golden Thyme DNA Tree

Tree using DNA profiles from the Golden Thyme DNA Study, demonstrating that T. citriodorus hort., now known as T. 'Culinary Lemon' and its cultivars, are distinct from the species T. pulegioides and T. vulgaris and that the lemon scented, golden leaved thymes should be regarded as T. pulegioides.
