Its habit, foliage, and flowers suggest a hybrid involving Thymus praecox subsp. britannicus, without a formal determination being possible. It is presented here with this reservation.
Sub-shrub of the Lamiaceae family, it forms a prostrate, dense, and very spreading carpet, only 2 to 5 cm in height, covering large areas uniformly and tightly. The foliage is small, bright green, visibly ciliated on the edges of the leaves, giving it a slight downy texture perceptible up close, without reaching the distinctly woolly character of some forms of Thymus praecox.
The flowers are pale lilac pink to medium pink, quite light and delicate, arranged in small loose heads that dot the carpet diffusely rather than covering it entirely. This airy and light flowering, irregularly distributed over the surface, contrasts with the forms with dense and homogeneous flowering. In cultivation, flowering is observed in June-July.
It requires well-drained soil, in full sun, and is particularly suitable for large rock gardens where it can spread freely between the stones.
