Thymus polytrichus subsp. britannicus
(Mother of thyme, Thyme)
This thyme grows to 6 inches tall, with fuzzy stems and tiny, rounded, fuzzy blue-green leaves. In summer, it produces clusters of very small white to lilac-pink flowers. Plants spread to about 9 inches wide. The leaves are aromatic but the strength of their scent varies according to the plant's site and the time of year.
