In early- to mid-summer, this mat-forming thyme erupts with masses of 6-inch-high spikes covered with pink flowers. The light green, tiny foliage, hugging the ground in mats, has a pleasing lemon fragrance when crushed. This plant shines when spilling over stone walls or between the cracks in paving stones, where passersby can tread on the leaves and release the lemony scent.

Woolly thyme—the wooliest of all thymes—forms a dense ground-covering mat of tiny, densely hairy leaves. The foliage has barely any fragrance and is unsuitable for culinary use. In summer, tiny pink tubular flowers appear. Plants grow to only one inch or so in height and spread to about a foot across.

One of the first thymes to flower each year, this charming and reliable cultivar bursts into bloom in early spring with unique salmon-pink flowers. Its fuzzy olive-green foliage forms a mat 1 to 2 inches tall and 18 inches wide. It is one of the most tolerant of thymes of dry conditions, but grows robustly with plenty of water.

This plant is an elegant addition to an herb or ornamental garden. It has lemon-scented green leaves edged in silver and produces lilac flowers in early summer.
